Description

[0001] This application is a divisional application of patent application No. 202580001953.6, entitled "A Pluggable Ear-Wearing Leg and Head-Wear Smart Device", filed on September 9, 2025, with a first priority date of June 4, 2025 and a second priority date of August 19, 2025. Technical Field

[0002] This invention relates to the field of head-mounted device technology, and more particularly to a detachable earpiece leg and a head-mounted smart device. Background Technology

[0003] Existing conventional eyeglasses typically have a fixed, non-detachable frame and temples, forming a single unit. Similarly, existing smart glasses and AI glasses often use a single-unit design for the frame and temples, meaning they are generally manufactured by the same company, lacking standardized interfaces, and offering poor disassembly, replacement, and expandability. This is particularly inconvenient for people with nearsightedness. Furthermore, the current structure of eyeglasses hinders the upgrade and iteration of smart AI glasses. Upgrading to smart AI glasses requires purchasing a complete set of products and lenses separately, increasing costs.

[0004] Some improved smart glasses replace the entire temple while keeping the front frame fixed. This is achieved by removing screws, plugging or snapping the temples together. However, this method still has the following drawbacks: (1) From the perspective of production process, the existing production method of separating the front frame and temples can only be adapted between specific manufacturers' own products. It is highly specific and has poor compatibility. This not only reduces the compatibility between components, especially since smart glasses temples are incompatible with ordinary glasses temples, but also increases the complexity of assembly, ultimately affecting production efficiency and restricting the large-scale application of smart glasses. (2) From the perspective of economic cost, when a single component (front frame or temple) is damaged, consumers are forced to replace the entire glasses system, resulting in the original intact optical lenses and corresponding frame components being left idle. This indivisible replacement mode not only increases the economic burden on consumers, but also causes a large amount of unnecessary waste of social resources.

[0005] The above background information is provided only to aid in understanding the concept and technical solution of this invention. It does not necessarily belong to the prior art of this patent application. In the absence of clear evidence that the above information was disclosed on the filing date of this patent application, the above background information should not be used to evaluate the novelty and inventiveness of this application. Summary of the Invention

[0006] To address the aforementioned technical issues, this invention proposes a pluggable ear-mounted support leg and a head-mounted smart device, which facilitates a reliable connection between the functional modules of the head-mounted device (especially smart glasses) and the supporting structure, and allows for quick manual replacement, thereby promoting standardization, modularization, and personalized customization, thus reducing costs and improving user experience.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: In a first aspect, the present invention discloses a pluggable earpiece leg for repeatedly plugging and unplugging by hand onto a pluggable external connector assembly, comprising a housing and an interface assembly. The housing has an ear-bend portion for fitting the wearer's auricle. A first opening is formed at a first end of the housing. The interface assembly includes a positioning component and a limiting component, both of which are disposed within a first cavity of the housing communicating with the first opening. The positioning component is used to position the connector in the pluggable external connector assembly. The limiting component is located at a position away from or near the first opening from the positioning component. The side is used to limit the insertion depth of the pluggable external connector after it breaks through the positioning member during insertion, or to limit the axial displacement of the positioning member caused by the impact of the external connector insertion. This allows the connector end of the pluggable external connector assembly to be adapted to the positioning member and the limiting member after being inserted from the first opening. A second cavity is provided at the end of the housing away from the first opening, and an electronic module is also provided in the second cavity. This allows the electronic module to be repeatedly plugged and unplugged by hand and worn on the ear through the housing and interface assembly.

[0008] Furthermore, the size of the first opening matches the size of the first end of the pluggable external connector assembly.

[0009] Furthermore, the positioning component is provided with at least one layer of flexible material, elastic material, or magnetic material.

[0010] Furthermore, the outer shell is provided with a bent portion, which is located on the outer shell above the wearer's auricle. The first cavity is located inside the outer shell in front of the wearer's auricle, and the second cavity is located inside the outer shell behind the wearer's auricle.

[0011] Furthermore, the outer casing has a charging port that communicates with the second cavity. The electronic module includes a power supply and electronic components. The electronic components are electrically connected to the power supply. The power supply has a power interface that is exposed at the charging port. The electronic components include at least one of an artificial intelligence module, a Bluetooth module, a wireless communication module, and an audio processing module.

[0012] Furthermore, the pluggable ear-wearing leg also includes an audio device. The outer shell has a third cavity located between the second cavity and the first cavity. The outer shell has a sound outlet hole that communicates with the third cavity. The sound outlet hole is directed towards the inside of the wearer's auricle. The audio device is located in the third cavity or the second cavity.

[0013] Furthermore, the sound outlet is located on the outer shell at a position corresponding to the front of the wearer's auricle, and the audio device is located in the second cavity or the third cavity inside the outer shell at a position corresponding to the back of the wearer's auricle. The third cavity is provided with a sound guiding channel, and the audio device communicates with the sound outlet through the sound guiding channel.

[0014] Furthermore, at least a flexible material layer is provided at at least a portion of the outer wall of the housing; the length of the pluggable earpiece leg is set such that the interface connecting the interface assembly to the pluggable external connector assembly is located between the front edge of the wearer's auricle and the front edge of the temple.

[0015] Furthermore, the positioning component is a positioning bead, a locking head, or a magnetic base. The positioning bead or the locking head protrudes from the inner wall of the first cavity along the path in which the first end of the pluggable external connector assembly is inserted from the first opening. The magnetic base is disposed on the limiting component.

[0016] The magnetic base includes at least one cylindrical or disc-shaped permanent magnet embedded or bonded to the limiting component. The magnetic base's attraction surface is a positioning surface, and the axis of the positioning surface is parallel to the insertion path direction. The limiting component and the magnetic base are configured such that the magnetic base can align and engage with the magnetic head of the inserted external connector. Thus, the interface is configured to be stably connected to the external connector by hand, allowing for repeated insertion and removal with near-zero resistance during insertion and near-zero friction during removal.

[0017] The flatness, planarity, and roughness of the permanent magnet in the magnetic holder, as well as its coaxiality, parallelism of the contact surface, and fit with the permanent magnet in the magnetic head of the external connector, are configured such that the magnet can automatically adjust to an axial alignment state by utilizing the self-centering effect provided by magnetic force, and the lateral deviation is corrected by the restoring force formed by the magnetic field gradient force, and the axial rotation is constrained by the magnetic moment, thus achieving automatic stabilization of multiple degrees of freedom; thereby, the pluggable earpiece support leg is configured to cooperate with the external connector to achieve single-handed linear hand-rubbed removal with minimal need to overcome sidewall friction.

[0018] Furthermore, the flatness, planarity, and roughness of the permanent magnet in the magnetic holder, as well as its coaxiality, parallelism of the contact surface, and fit with the permanent magnet in the magnetic head of the external connector, are configured such that the permanent magnet can automatically adjust to an axial alignment state by utilizing the self-centering effect provided by the magnetic force, and the lateral offset can be corrected by the restoring force formed by the magnetic field gradient force, and the axial rotation can be constrained by the magnetic moment. This, together with the external pluggable temple connector assembly, achieves multi-degree-of-freedom automatic stabilization after attraction.

[0019] Furthermore, the interface also includes a guide cavity, through which the external connector can be inserted from the opening end of the interface and moved along the guide cavity until it is attracted and positioned by the magnetic base; the magnetic pole direction of the permanent magnet in the magnetic base is parallel to the length direction of the guide cavity, and the permanent magnet is at least partially embedded in the base within the interface assembly body or bonded to the base within the interface assembly body, and at least one end face of the permanent magnet faces the opening end, the end face facing the opening end being a magnetic attraction surface for attracting the external connector, and the direction of the attraction force is parallel to the guiding direction of the guide cavity; the length of the temple interface assembly is configured to be gripped by the middle, ring, and little fingers; thus, the interface is configured to be able to be rubbed apart from the external connector with one hand in a straight line with minimal need to overcome sidewall friction.

[0020] Furthermore, the positioning bead is a spherical elastic protrusion or a hemispherical elastic protrusion, and the locking head is a boss-shaped elastic protrusion.

[0021] Furthermore, there are at least two positioning beads or locking heads, and at least two positioning beads or locking heads are respectively fixed on opposite inner walls of the first cavity.

[0022] Furthermore, there are at least two positioning beads or locking heads, each of which is arranged along the path direction from the first opening into the first end of the pluggable external connector assembly, and each of which has a different size.

[0023] Furthermore, the positioning bead or the locking head comprises a metal or plastic body, and the metal or plastic body is provided with an anti-slip layer. The diameter of the metal or plastic body of the positioning bead is 2mm~4mm, and the elasticity of the positioning bead is 8N~12N. The length of the metal or plastic body of the locking head is 2mm~4mm, the width is 2mm~4mm, the height is 1.3mm~1.7mm, and the locking force of the locking head is 8N~12N.

[0024] The magnetic holder is made of N42-N55 grade neodymium iron boron high energy product material (BHmax, measured in MGOe or kJ / m³). The magnetic holder is cylindrical with a length of 4-6 mm, of which 1-2 mm is embedded in the interface assembly body, and 2-5 mm is exposed. Its diameter is 2-4 mm, and the exposed end face is the attraction surface. Its dimensions, magnetization direction, and layout are configured to generate an axial attraction force of 0.45-11.5 N with the magnetic head of the external connector. It also includes a guide cavity 16, the cross-section of which is square or flat in at least a portion along its length, and the magnetic poles of the permanent magnet are primarily parallel to the length of the guide cavity. This restricts rotation between the pluggable earpiece legs and the external connector, thereby providing dynamic passive stability during insertion or after disengagement from automatic stabilization, resulting in a better user experience. For example, the force, direction of force, and force application mode are more in line with user habits, especially for straight insertion and removal, avoiding rotation and shaking, thus improving the user experience during insertion and removal. The interface is configured to be able to be straight-line tucked away from the external connector with one hand, reducing the chance of touching the sidewalls. Ideally, there should be virtually no need to overcome sidewall friction, reducing wear and allowing for more insertion and removal cycles.

[0025] Furthermore, the limiting component is a limiting plate, limiting wall, limiting rib, or limiting post disposed in the first cavity on the side away from the first opening, and the surface of the limiting component is perpendicular to the path direction of the first end of the pluggable external connector assembly inserted from the first opening, which can axially limit the magnetic base. The magnetic base is made of N52 grade neodymium iron boron high magnetic energy product material; its size, magnetization direction, and layout are configured to generate an axial attraction force of 1.2-8N with the magnetic head of the external connector; the distance for the external connector to move within the guide cavity is less than 10mm.

[0026] In a second aspect, the present invention discloses a head-mounted smart device, comprising a device body, a pluggable external connector assembly, and the pluggable ear support legs described in the first aspect. The pluggable ear support legs are repeatedly plugged and unplugged by hand to a first end of the pluggable external connector assembly, and the second end of the pluggable external connector assembly is fixedly connected to the device body.

[0027] Furthermore, the head-mounted smart device is one of smart glasses, smart helmets, AR head-mounted displays, or headphones, and its electronic components are only housed within the detachable earpiece legs; the length of the detachable earpiece legs and the length of the front legs are configured to be gripped by the middle, ring, and little fingers, thereby enabling the head-mounted smart device to be detached by a single hand in a straight line from both directions.

[0028] Thirdly, the present invention discloses a pluggable temple for eyeglasses, the temple comprising a pluggable connector assembly and a pluggable earpiece as described in the first aspect, the pluggable earpiece being repeatedly plugged and unplugged by hand to the first end of the pluggable connector assembly; the length of the pluggable earpiece and the length of the foreleg are both configured to be gripped by the middle, ring, and little fingers, thereby the pluggable temple is configured to be able to be pulled open by a single hand in a straight line from both directions.

[0029] Furthermore, the size of the opening matches the size of the temple end of the eyeglass frame.

[0030] Furthermore, the positioning component is provided with at least one layer of flexible material.

[0031] Furthermore, the temple of the glasses also includes an electronic module, and a second cavity is provided inside the housing, in which the electronic module is placed.

[0032] Furthermore, the housing is provided with a bent portion, the first cavity is provided at the front end of the bent portion, and the second cavity is provided at the rear end of the bent portion.

[0033] Furthermore, the housing is provided with a charging port that communicates with the second cavity. The electronic module includes a power supply and electronic components. The electronic components are connected to the power supply, and the charging port is connected to the power supply.

[0034] Furthermore, a third cavity is disposed within the housing between the second cavity and the first cavity, and a sound outlet is provided on the housing communicating with the third cavity; the temple of the eyeglasses also includes an audio device, which is disposed in the third cavity or the second cavity.

[0035] Furthermore, the electronic components include an artificial intelligence module, a Bluetooth module, a wireless communication module, or an audio processing module.

[0036] Furthermore, the sound outlet is located on the housing near the front end of the third cavity; the audio device is located near the rear end of the third cavity or in the second cavity near the third cavity; the audio device is connected to the sound outlet through the sound transmission channel in the third cavity.

[0037] Furthermore, at least one layer of plastic is provided on the outside of the housing.

[0038] Furthermore, the positioning component is a positioning bead.

[0039] Furthermore, the positioning bead has a diameter of 2-4mm and a length of 2-4.0mm, and an elasticity of 8-12N.

[0040] Furthermore, the positioning component is a snap-fit.

[0041] Furthermore, the fixed buckle is 2-4mm long * 2-4mm wide * 1.3-1.7mm high, and the buckling force is 8-12N.

[0042] Furthermore, the sound outlet is located at the temple corner in front of the ear when worn.

[0043] Fourthly, the present invention discloses a pluggable eyeglass, which includes an eyeglass frame and the pluggable temples described in the third aspect; the eyeglass frame includes a lens frame and at least two front temples, one end of the front temples is connected to the lens frame, and the other end of the front temples is inserted into the opening of the pluggable temples and positioned in cooperation with the positioning component.

[0044] Furthermore, the length of the pluggable earpiece temple is 3 / 4 to 1 / 4 of the total temple length of the glasses. When an electronic module is included, the electronic module is only located inside the pluggable temple.

[0045] In the above technical solution, the length of the pluggable earpiece leg and the length of the front leg are both configured to be able to be held by the middle finger, ring finger and little finger, so that the pluggable glasses are configured to be able to be pulled open by one hand in a straight line from both directions.

[0046] Compared with the prior art, the beneficial effects of the present invention are as follows: The pluggable earpiece leg disclosed in the present invention is used to be repeatedly pluggable and detachable by hand to a pluggable external connector assembly. A positioning component and a limiting component are provided in a first cavity communicating with a first opening inside the outer shell, so as to form a stable connection with the pluggable external connector assembly. This achieves a quick pluggable and detachable structure between the pluggable earpiece leg and the pluggable external connector assembly, realizing a standardized interface design for the manually repeatedly pluggable earpiece leg, improving interchangeability to be compatible with multiple types of frames, and By reducing production complexity, this invention addresses the technical problems of inconvenient disassembly, high production costs, and low resource utilization in existing smart glasses and other head-mounted smart devices. Consumers no longer face the dilemma of choosing between regular glasses, smart glasses, or two pairs; instead, they simply carry an accessory similar to an earphone charging case containing the reusable, manually pluggable temple interface component described in this application for easy replacement. Since earphone charging cases are already a necessity for many, carrying an additional accessory like this will not be inconvenient for most consumers. Therefore, this invention, through a standardized and user-friendly quick-change interface, decouples the functional modules of the head-mounted device from its supporting structure, ultimately significantly improving product compatibility, maintainability, customizability, and user experience, while reducing the overall lifecycle cost.

[0047] In some embodiments, the glasses can be opened with one hand in both directions. This eliminates the need to adjust the direction of the temples during operation, making it more convenient.

[0048] In a further embodiment, the present invention also has the following beneficial effects: (1) By placing the positioning component on the inner sidewall or limiting component in the path direction of the housing from the first opening, it is convenient for the user to repeatedly insert and remove the housing by hand.

[0049] (2) When the positioning component is a positioning bead or a locking head, at least two positioning beads or locking heads can be provided on the opposite inner sidewalls of the first cavity to enhance the connection stability between the pluggable external connector assembly and the pluggable earpiece legs.

[0050] (3) Multiple positioning beads or clips are arranged in the path direction from the first opening of the first end of the pluggable external connector assembly, and the sizes are different. On the one hand, they can be adapted to pluggable external connector assemblies of different sizes, and on the other hand, the length of the overall ear support leg can be adjusted.

[0051] (4) When the positioning component is a magnetic base, the position setting of the positioning component and the limiting component, as well as the setting of the guide cavity, determine that it is inserted and removed back and forth without rotation or swinging during operation. With the appropriate insertion and removal force design and the design of the plug movement distance during insertion and removal, ordinary adults can easily "rub open" the connection between the interface and the connector with one hand in a straight line when disassembling (pinch the front end with the thumb and forefinger, hold the back end with the other three fingers, and use the pinching friction of the thumb and forefinger to push forward forcefully), avoiding the problem of breaking or knocking off glasses due to excessive force when operating with both hands. Since there is basically no need to overcome the friction of the side wall, wear can be reduced and the number of insertions and removals can be increased. The magnetic attraction of this application provides a static automatic stabilization mechanism with main connection force and self-alignment, and the guide cavity and the limiting component work together to restrict the degree of freedom, providing a dynamic passive stabilization mechanism; their synergistic effect achieves a stable connection and facilitates freehand operation, solving the contradiction between stability and convenience.

[0052] (5) This application uses the ear bend (bent part) as the boundary, with a rear speaker and a front sound outlet. The speaker and the sound outlet are not adjacent, but connected by a sound guide channel. On the one hand, the sound quality is improved by the reflection and resonance of sound in the sound guide channel (the length and cross-sectional changes of the sound guide channel can be used for necessary acoustic tuning to adapt to the characteristics of audio devices). On the other hand, it greatly removes the positional restrictions on the speaker, freeing up valuable design space for the interface components. The sound outlet is directed towards the inside of the wearer's auricle. In this way, most of the sound emitted is focused and directed by the auricle, which not only does not affect the sound quality, but also does not cause interference to people next to you, thus solving the contradiction that earplugs are impolite and that playing sound out loud affects others.

[0053] Other beneficial effects of the embodiments of the present invention will be further described below. Attached Figure Description

[0061] The embodiments of the present invention will be described in detail below. It should be emphasized that the following description is merely exemplary and not intended to limit the scope and application of the present invention.

[0062] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it can be directly or indirectly attached to that other component. When a component is referred to as "connected to" another component, it may be directly or indirectly connected to that other component. Furthermore, a connection can be used for both fixing and circuit / signal connectivity.

[0063] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0064] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of the present invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0065] It is worth noting that the terms "front" and "rear" in this application are distinguished by their length along the outer shell.

[0066] Example 1 like Figure 1 and Figure 2 As shown, a preferred embodiment of the present invention provides a pluggable earpiece leg 10 for repeatedly pluggable and detachable connection to a pluggable external connector assembly 20 by hand. It includes a housing 11 and an interface assembly 12. The housing has an ear-bend portion for matching the wearer's auricle. A first opening 111 is formed at the first end of the housing 11. The interface assembly 12 includes a positioning component 121 and a limiting component 122. Both the positioning component 121 and the limiting component 122 are disposed within a first cavity 112 communicating with the first opening 111 inside the housing 11. The positioning component is used to position the connector in the pluggable external connector assembly. The limiting component 122 is located away from or away from the positioning component 121. Near the first opening 111, a limiting device is provided for the pluggable external connector, limiting the insertion depth of the external connector after it breaks through the positioning member during insertion, or limiting the positioning member to limit the degree of axial displacement of the positioning member caused by the impact of the external connector insertion; thereby enabling the connector end of the pluggable external connector assembly 20 to be simultaneously adapted to the positioning member 121 and the limiting member 122 after being inserted from the first opening 111; a second cavity is provided at the end of the housing away from the first opening, and an electronic module is also provided in the second cavity; thereby enabling the electronic module to be repeatedly plugged and unplugged by hand and worn on the ear through the housing and interface assembly.

[0067] "Can be repeatedly inserted and removed by hand" means that it can be done by hand without the need for tools such as screwdrivers, including insertion and removal with both hands or one hand.

[0068] In order to be able to pry it open by hand, the pinching force of an adult's thumb and forefinger, the material and coefficient of friction of the interface component 12 and the pluggable external connector component 20 described below, and the dimensions (mainly thickness) of the interface component 12 and the pluggable external connector component 20 described below must be taken into consideration. A detailed discussion follows: Assuming the total outer diameter of the interface component housing is between 3-9mm (the cross-sectional length and width are between 3-9mm; note: the matching relationship between the magnet size and the housing size should ensure that the housing still has a reasonable wall thickness after the magnet is embedded (recommended not less than 0.5mm)), then when pulling it out with both hands, the ideal upper limit of the pull-out force under wet conditions is 1.8-8N, and the maximum ideal upper limit can reach 11.5N in a dry environment; when pulling it out with one hand, the ideal upper limit of the pull-out force under wet conditions is 1.5-5.5N, and the maximum ideal upper limit can reach 8N in a dry environment; however, the above ideal upper limit range is only for discussion and is not a limitation on the upper limit range; the upper limit range can also be improved through dynamic reinforcement measures, such as: adding cross groove patterns to the housing surface, using diamond micro-etching, and high friction coefficient TPU coating, etc.

[0069] This embodiment allows for manual insertion and removal without tools, providing a foundation for standardization. This is because when tools are required for insertion and removal, consumers typically rely on manufacturers and repair shops. These shops have the opportunity to market their own parts, and manufacturers tend to make their interfaces incompatible, thus increasing sales. However, if consumers can perform insertion and removal manually, they can replace parts without relying on manufacturers or repair shops. Consumers will then tend to seek standard interfaces to increase their choices. Manufacturers, in turn, are more inclined to adopt standardized interfaces to expand sales. Therefore, the ability to repeatedly insert and remove parts manually provides a foundation for standardization.

[0070] In this embodiment, the pluggable earpiece temple 10 can be used as the pluggable eyeglass temple. The first end of the pluggable external connector assembly 20 is, for example, the front temple 2 of the external eyeglass frame 1, and the front temple is provided with a positioning mating part to cooperate with the positioning component 121.

[0071] The positioning component 121 may be disposed on the inner sidewall of the pluggable external connector assembly 20 within the first cavity 112 along the path in which the first end is inserted from the first opening 111. The positioning component 121 is provided with at least one layer of flexible material, elastic material, or magnetic material.

[0072] refer to Figure 2 and Figure 3In this example, the positioning component 121 is a positioning bead 121A, which protrudes from the inner wall of the first cavity 112. The positioning bead 121A is either a spherical or hemispherical elastic protrusion. When the positioning bead 121A is a spherical elastic protrusion, the lower hemisphere is elastically embedded in the inner wall of the first cavity 112, and the upper hemisphere protrudes from the inner wall of the first cavity 112. When the positioning bead 121A is a hemispherical elastic protrusion, an elastic component can be directly formed below the hemispherical structure to create the positioning bead 121A. Furthermore, the positioning bead 121A includes a metal or plastic body, and the metal or plastic body is provided with an anti-slip layer. The diameter of the metal or plastic body is 2mm to 4mm, and the elasticity of the positioning bead is 8N to 12N. The anti-slip layer is, for example, a surface corrugated texture. In other embodiments, a flexible material layer with a Shore hardness of 20A to 50A can also be disposed on the surface of the positioning bead 121A to provide an anti-slip function. (See reference) Figure 4 and Figure 5 In other embodiments, the positioning component 121 is a locking head 121B, which also protrudes from the inner wall of the first cavity 112. The locking head 121B is a boss-shaped elastic protrusion. Further, the locking head 121B also includes a metal or plastic body, and the metal or plastic body is provided with an anti-slip layer. The length of the metal or plastic body of the locking head is 2mm~4mm, the width is 2mm~4mm, the height is 1.3mm~1.7mm, and the locking force of the locking head is 8N~12N.

[0073] refer to Figure 2 and Figure 4 In this example, there is one positioning bead 121A or one locking head 121B, which protrudes from the lower or upper side wall of the first cavity 112. (See reference) Figure 3 and Figure 5 In some embodiments, there are two positioning beads 121A or two locking heads 121B. The two positioning beads 121A or two locking heads 121B are disposed opposite to each other on the inner sidewall of the first cavity 112. For example, the two positioning beads 121A or two locking heads 121B protrude opposite to each other on the upper sidewall and the lower sidewall, or opposite to each other on the left sidewall and the right sidewall. In other embodiments, the number of positioning beads 121A or locking heads 121B can be three or more. Multiple positioning beads 121A or locking heads 121B can be arranged relative to each other on the inner wall of the first cavity 112, or they can be arranged on the inner wall of the first cavity 112 along the path direction of insertion from the first opening 111 at the first end of the pluggable external connector assembly 20, so that the distance between each positioning bead 121A or locking head 121B and the first opening 111 is different, so that the overall length of the earpiece support leg can be adjusted. In addition, the size of each positioning bead 121A or locking head 121B can also be different to accommodate pluggable external connector assemblies 20 of different sizes.

[0074] In other embodiments, the positioning component 121 may be a positioning bead 121A or a locking head 121B, or it may be a pin, thread, magnetic clasp, or other structure. Correspondingly, the adapter structure of the pluggable external connector assembly 20 is also adjusted according to the positioning component 121.

[0075] refer to Figure 2 The limiting component 122 is a limiting plate, limiting wall, limiting rib, or limiting post disposed in the first cavity 112 on the side away from the first opening 111. The surface of the limiting component is perpendicular to the path direction of the first end of the pluggable external connector assembly 20 inserted from the first opening 111. The distance between the limiting component 122 and the positioning component 121 is equal to the distance between the first end of the pluggable external connector assembly 20 and its corresponding groove. This allows the first end of the pluggable external connector assembly 20 to be blocked by the limiting component after it is inserted from the first opening 111, thus achieving the limiting function.

[0076] In some embodiments, the distance between the interface component 12 and the end of the housing 11 away from the first opening 111 is 80mm to 150mm, or the overall length of the housing 11 is 80mm to 150mm, preferably 130mm.

[0077] refer to Figure 6The pluggable external connector assembly 20 includes a bracket body 21 and a connector 22. A recess is provided on the side wall of the bracket body 21 near its first end, forming the connector 22. After the first end of the bracket body 21 is inserted into the housing 11 through the first opening 111, the connector 22 is adapted to the positioning member 121, and the end of the first end of the bracket body 21 is adapted to the limiting member 122. The recess forming the connector 22 can receive the positioning bead 121A or the locking head 121B that constitutes the positioning member 121. The end of the first end of the bracket body 21 abuts against the limiting member 122, forming a stable connection. The size of the first opening 111 matches the size of the first end of the support body 21. For example, the shape and size of the first opening 111 are equal to the shape and size of the cross-section of the first end of the support body 21, or there is a gap fit between the two. This further ensures a stable connection between the pluggable earpiece temple 10 and the pluggable external connector assembly 20, so as to limit the first end of the pluggable external connector assembly 20 from shaking in the first cavity 112 through the outer shell 11. For example, the pluggable external connector assembly is the front temple 2 of the eyeglass frame 1, and the size of the opening matches the size of the end of the temple of the eyeglass frame. The length of the pluggable earpiece temple is set so that the interface connecting the interface assembly 12 and the pluggable external connector assembly 20 is located between the front edge of the wearer's auricle and the front edge of the temple, so that the interface can be hidden in the temple hair and not easily noticed. This makes it look like an ordinary pair of glasses, which is convenient for fashionable clothing.

[0078] Furthermore, another advantage of having a functional module or electronic module located only within the interface component body 3 of the pluggable temple interface component is that, when worn, with the ear as the fulcrum, the functional module or electronic module and the lens become a counterweight to balance each other, reducing the weight on the bridge of the nose and transferring some or all of the pressure to the ear; ideally, it can achieve near-zero weight on the bridge of the nose, thereby relieving the pressure on the bridge of the nose of people who wear glasses for a long time.

[0079] Example 2 refer to Figure 7 and Figure 8 In this example, the detachable earpiece leg also includes an electronic module. A second cavity 113 is provided at the end of the outer shell 11 away from the first opening 111, and the electronic module is disposed within the second cavity 113. Figure 9The outer shell 11 has a bent portion 114, which is located above the wearer's auricle 30. A first cavity 112 is located inside the outer shell 11 in front of the wearer's auricle, and a second cavity 113 is located inside the outer shell 11 behind the wearer's auricle 30. This design allows for the placement of larger or heavier electronic modules behind the auricle 30, effectively utilizing the internal space of the pluggable ear support leg 10. This reduces weight in front of the bent portion 114 (in front of the auricle), balancing the pressure of the front structure of the head-mounted smart device on the bridge of the nose and the pressure of the pluggable ear support 10 on the auricle 30, thus improving wearing comfort. For example, in a specific embodiment, the outer shell has a bent portion 114, the first cavity 112 is located at the front end of the bent portion 114, and the second cavity 113 is located at the rear end of the bent portion 114.

[0080] The outer casing 11 has a charging port that connects to the second cavity 113. The electronic module includes a power supply 14 and an electronic component 13. The electronic component 13 is electrically connected to the power supply 14. The power supply 14 has a power interface that is exposed at the charging port. The electronic component 13 is, for example, a PCBA (Printed Circuit Board Assembly), which includes at least one of an artificial intelligence module, a Bluetooth module, a wireless communication module, and an audio processing module. The wireless communication module can be, but is not limited to, an NFC module or a Wi-Fi module. For example, the casing has a charging port that connects to the second cavity 113 and is connected to the power supply.

[0081] In some embodiments, the pluggable earpiece leg further includes an audio device 15. A third cavity 115 is also provided within the outer shell 11, located between the second cavity 113 and the first cavity 112. A sound outlet 116 communicating with the third cavity 115 is provided on the outer shell 11. The audio device 15 is disposed in either the third cavity 115 or the second cavity 112. In this embodiment, the sound outlet 116 is located on the outer shell 11 at a position corresponding to the front of the wearer's auricle 30 (e.g., at a position corresponding to the temple), and the sound outlet direction is aligned with the inner side of the wearer's auricle. The audio device 15 is disposed within the second cavity 112 or the third cavity 115 within the outer shell 11 at a position corresponding to the rear of the wearer's auricle 30. A sound guide channel is provided in the third cavity 115, and the audio device 15 communicates with the sound outlet 116 through the sound guide channel. The audio device 15 may be, but is not limited to, a loudspeaker, a megaphone, or a miniature speaker. By placing the audio device 15 at the rear and separating it from the sound outlet 116, the audio device 15 is connected to the sound outlet 116 through a sound guide channel in the third cavity. That is, the sound emitted by the audio device 15 first passes through the sound guide channel before being emitted from the sound outlet 116. In this way, the audio device 15 is further away from the sound outlet 116, and the sound is not directly emitted and then transmitted from the sound outlet 116, but must first pass through the sound guide channel. This not only allows for more flexible positioning of the sound outlet 116 and the audio device 15, but also provides space for sound quality design. Through the special design of the sound guide channel, sound can undergo reverberation and resonance within the cavity, improving sound quality before being emitted from the sound outlet 116. The sound outlet 116 can, for example, be an array of circular holes with a diameter of 0.5mm to 2mm. In a specific example, the sound outlet 116 is located on the housing near the front end of the third cavity 115; the audio device 15 is located near the rear end of the third cavity 115 or in the second cavity 112 near the third cavity 115; the audio device 15 is connected to the sound outlet 116 through the sound transmission channel (i.e., the sound guiding channel) in the third cavity 115.

[0082] In some embodiments, the outer shell 11 may be, but is not limited to, plastic titanium, which has the advantages of being ultra-lightweight, impact-resistant, high-temperature resistant (able to withstand high temperatures of 110°C), and highly elastic. The outer shell 11 may also be made of silicone material, which has the advantages of being highly elastic and resistant to aging, such as thermoplastic rubber (TPR) or thermoplastic elastomer (TPE). In addition, at least a portion of the outer wall of the outer shell 11 is provided with a flexible material layer, an elastic material layer, or a magnetic material layer, such as plastic, which can increase the comfort of the temples.

[0083] This invention also provides a head-mounted smart device, including a device body, a pluggable external connector assembly, and the aforementioned pluggable earpiece legs. The pluggable earpiece legs are repeatedly pluggable and detachable by hand to the first end of the pluggable external connector assembly, and the second end of the pluggable external connector assembly is fixedly connected to the device body. The head-mounted smart device can be one of smart glasses, AR head-mounted displays, or headphones, and its electronic components are only housed within the pluggable earpiece legs. The length of the pluggable earpiece legs and the length of the front legs are configured to be gripped by the middle, ring, and little fingers, thereby enabling the head-mounted smart device to be opened and closed by a single hand in a straight line from both directions. The electronic components of the head-mounted smart device are only housed within the pluggable earpiece legs.

[0084] refer to Figures 10 to 12 Another preferred embodiment of the present invention discloses a smart glasses, including an eye socket component 40 (i.e., a frame), a pluggable external connector assembly 20 (i.e., a front temple), and a pluggable earpiece temple 10 (i.e., a pluggable eyeglass temple). The second end of the pluggable external connector assembly 20 is fixedly connected to the eye socket component 40 (e.g., by screws). The pluggable earpiece temple 10 and the pluggable external connector assembly 20 are adapted to form an integral eyeglass temple portion, i.e., the pluggable earpiece temple 10 corresponds to the rear temple portion of the eyeglass temple, and the pluggable external connector assembly 20 corresponds to the front temple portion of the eyeglass temple. The outer shell 11 of the pluggable earpiece temple 10 can be a plastic shell or a metal shell. In a specific example, the eye socket component 40 (i.e., the frame) and at least two pluggable external connector assemblies 20 (i.e., the temples) constitute the eyeglass frame part. One end of the temple is connected to the frame, and the other end of the temple is inserted into the opening of the pluggable temple. The positioning recess provided on the temple is engaged with the positioning component.

[0085] The length of the detachable earpiece temple 10 can be less than or equal to 1 / 2 of the overall length of the eyeglass temple, for example, 1 / 3, or the length of the detachable earpiece temple 10 can be 80mm to 150mm of the tail portion of the eyeglass temple. For example, in a specific instance, the length of the detachable earpiece temple 10 is 3 / 4 to 1 / 4 of the total length of the eyeglasses.

[0086] The preferred embodiment of the present invention provides a first opening 111 and a first cavity 112 at the front end of the outer shell 11 of the pluggable ear-wearing leg 10. A limiting component 121 is provided in the first cavity 112. For the manufacturer, as long as a hole is drilled or a limiting groove (collectively referred to as "positioning recess") is opened on the front leg of a regular eyeglass frame, it can be connected to the pluggable ear-wearing leg 10 (the rear leg part of the eyeglass frame) of this application. For the user, when upgrading to smart glasses, it is not necessary to buy the entire pair of glasses, but only the rear leg part of the eyeglass frame (i.e., the pluggable ear-wearing leg 10). When changing lenses, it is also not necessary to buy the entire pair of glasses, but only the frame can be purchased to connect with the eyeglass frame of this application. This is more convenient for both the manufacturer and the user, and improves the convenience and compatibility of eyeglass production and replacement. In addition, the present invention provides a limiting component 122 at the end of the first cavity 112 away from the opening. After the front part of the temple on the frame (i.e., the pluggable external connector assembly 20) passes through the first opening 111, it can be matched with the positioning component 121 more quickly by the limitation of the limiting component 122, so as to achieve quick fixation and further improve the convenience of use.

[0087] In this embodiment, all electronic components are located within the housing 11 of the pluggable earpiece leg 10, while the pluggable external connector assembly 20 contains no electronic components. This makes it very easy for eyewear manufacturers to produce, allowing them to enter the smart glasses market simply by setting up a connector, greatly enriching the styles of smart glasses. On the other hand, smart wearable device manufacturers do not need to consider eyewear manufacturing processes and styles; they only need to provide an interface component to adapt to thousands of different eyewear styles. The pluggable external connector assembly and the interface component form a standard interface, which is very beneficial for standardized mass production.

[0088] This invention optimizes the layout of core components for smart glasses by integrating larger components such as electronic components 13, power supply 14, and audio devices 15 at the rear (see reference). Figure 7 and Figure 8 This design fully utilizes the space at the back of the temples, effectively solving the problem of unused space at the point where the temples contact the ears, improving the flexibility of the internal component layout, optimizing the overall performance of the device, and providing more possibilities for the functional expansion of smart glasses.

[0089] Figures 10 to 12The image shows a smart glasses with quick-release temples. Its principle is an improvement on conventional glasses, making the temples removable by hand. When disassembled, they consist of separately sold front temples (corresponding to the aforementioned removable external connector assembly 20) and rear temples (corresponding to the aforementioned removable earpiece support 10), which, when plugged in, form a single unit. The rear temple contains a built-in functional module (e.g., an audio device) or electronic module. The front temple may or may not contain a functional or electronic module. The image shows the front and rear temples plugged in as a single unit. Figure 10 As shown, the front and back temples of the glasses are separated as follows: Figure 11 As shown, the front frame of the glasses is separated from both the front and back temples. Figure 12 As shown.

[0090] The temples can be made of ordinary plastic, or special materials such as silicone rubber, antibacterial materials, titanium alloy, silver-containing materials, expensive metals, or jewelry to increase comfort, antibacterial properties, or a sense of luxury (so people tend to replace the front temples while keeping the back temples); the temples can also be different fashionable fast-fashion styles to enhance the sense of style (so people tend to replace the back temples while keeping the front temples); the temples can also be partially detachable; all functional modules are located in the pluggable part so that the other part can still be hooked on the ear after disassembly, without affecting the wearing of the glasses.

[0091] The design principle of this invention is based on existing ordinary glasses, where the front frame and the front temple (front end of the temple) are still a whole, and the basic structure of the original glasses is maintained as much as possible. The only difference is that the interface component located 8cm to 13cm away from the rear temple (end of the temple) is designed as a pluggable section (i.e., the distance between the interface of the temple interface component and the end is 8cm to 13cm), which is called a pluggable temple connector component. It can be connected to the pluggable temple interface component. The pluggable temple interface component can be a smart glasses temple module that can be quickly detached or an ordinary temple module. The front temples of the glasses feature a pluggable external connector assembly 20, while the rear temples feature pluggable earpiece supports 10. These components are connected via a special method, including but not limited to structures such as clips (2mm-4mm in length and width, with a clamping force of 8N-12N; preferably 3.0mm long * 3.0mm wide * 1.5mm high, with a clamping force of 10N), positioning beads (2mm-4mm in diameter, with a spring force of 8N-12N; preferably 3mm in diameter, with a spring force of 10N), pins, and threads. This allows the glasses to be integrated with the temples and front frame, enabling switching between smart glasses and regular glasses. This quick, manual plugging and unplugging method expands the smart application upgrades of regular glasses, allowing them to connect to AI smart modules, Bluetooth headsets, and audio modules to enhance their technological appeal, as well as ordinary plastic temples. It can use TR-90 (plastic titanium), which is ultra-lightweight, impact-resistant, high-temperature resistant (can withstand temperatures up to 110℃), and highly elastic; or silicone temples, such as those made of TPR or TPE, which are highly elastic and resistant to aging. In addition, other special materials can be used to enhance comfort. For example... Figure 20 As shown, when using smart glasses, insert the pluggable external connector assembly 20 (front temple of glasses) of the smart glasses (optical frame) with optical lenses into the pluggable earpiece temple 10 (back temple of glasses) as indicated by the arrow in the figure.

[0092] Example 3 like Figures 13 to 19 This is a schematic diagram of another embodiment of the present invention. Figure 14 This is an exploded view of the interface structure (including connector components and interface components). Figure 15This is an exploded view of an eyeglass with detachable temples. Both the magnetic base 50 and the magnetic head 51 are equipped with permanent magnets 52, which are made of materials such as AlNiCo, IronChromiumCo, SamariumCo, NeodymiumIronBoone, permanent magnet ferrite, composite permanent magnet, rare earth cobalt (such as SamariumCo), and platinum-cobalt alloy. The magnetic base 50 includes at least one cylindrical or disc-shaped permanent magnet embedded or bonded to the limiting member 122. The magnetic base 50 is disposed on the limiting member (base 53), and the magnetic base's attraction surface is a positioning surface, with the axis of the positioning surface parallel to the insertion path direction. The limiting member and the magnetic base are configured such that the magnetic base can align and engage with the magnetic head of the inserted external connector. Thus, the interface is configured to be stably connected to the external connector by hand with repeated insertion and removal, approaching zero resistance during insertion and approaching zero friction during removal. Utilizing the self-centering effect provided by magnetic force, the magnet automatically adjusts to an axially aligned state, and lateral deviation is corrected by the restoring force formed by the magnetic field gradient force, while axial rotation is constrained by the magnetic moment, achieving multi-degree-of-freedom automatic stabilization. Thus, the pluggable earpiece leg is configured to cooperate with the external connector to achieve repeated single-handed insertion and removal with no friction during removal. The limiting plate axially limits the magnetic base 50, restricting its axial displacement caused by the insertion impact of the pluggable external connector assembly. It also buffers and protects the permanent magnet 52 from insertion and removal impacts. The limiting plate is constructed to axially limit the magnetic base; its elasticity buffers and protects the permanent magnet from insertion and removal impacts. Materials used include PP, PC, EPP, TPR, and TPE. In this embodiment, the pluggable temple interface assembly uses magnetic positioning for the interface structure. Figure 13 As shown, the positioning component of the interface assembly is a magnetic base 50, which cooperates with the magnetic head 51 on the connector for positioning through magnetic attraction. The magnetic force level of the magnetic base is selected between N42 and N55, preferably N52. The magnetic base is cylindrical, with a length of 4-6mm, preferably 5mm, of which 1-2mm, preferably 1.5mm, is embedded in the interface assembly body, and 2-5mm, preferably 3.5mm, is exposed. The diameter is 2-5mm, preferably 3mm. A magnetic base diameter <1.5mm is not recommended, as the magnetic base area is close to a pinhead and inoperable. Its exposed end face is the attraction surface. The magnetic field configuration of the magnetic base 50 and the magnetic head 51 provides sufficient lateral restoring force to ensure automatic magnetic alignment when there is an initial lateral deviation between the connector and the interface less than a specified value (e.g., 0.5mm).

[0093] The flatness, planarity, and roughness of the permanent magnet in the magnetic holder, as well as its coaxiality, parallelism of the contact surface, and fit with the permanent magnet in the magnetic head of the external connector, are configured such that the permanent magnet can automatically adjust to an axial alignment state by utilizing the self-centering effect provided by magnetic force, and the lateral offset can be corrected by the restoring force formed by the magnetic field gradient force, and the axial rotation can be constrained by the magnetic moment. This, together with the external pluggable temple connector assembly, achieves multi-degree-of-freedom automatic stabilization after attraction.

[0094] The “embedding” can be done in one of the following ways: (1) the permanent magnet is pressed into the precision hole on the limiting plate by interference fit; (2) the limiting plate is provided with a claw / ring structure to lock the permanent magnet axially; (3) after the permanent magnet is embedded, it is fixed by injection molding.

[0095] If bonding is used, a high-strength, aging-resistant structural adhesive should be selected, and the bonding surfaces should be kept clean. The bonding strength should be verified by insertion and extraction tests.

[0096] Alternatively, embedding and bonding can be used to further increase stability.

[0097] For stable attraction, the ideal lower limit of the attraction force for permanent magnets with a diameter of 2-5mm is 0.45-1.5N. However, the lower limit of the attraction force is also affected by other factors and can be lowered through certain measures, such as reducing the air gap size, using multi-pole magnetization or a Halebeck array, selecting high coercivity materials, and selecting high remanence materials. This can achieve a lower lower limit of the attraction force while still maintaining stable attraction. Adding magnetically conductive materials (such as electrical pure iron) to the magnetic base 50 and magnetic head 51 can guide the magnetic field distribution, reduce magnetic leakage, and improve the effective attraction force. The aforementioned "assuming the total outer diameter of the interface assembly housing is between 3-9mm" refers to the size of the housing after the permanent magnet is fitted with a housing.

[0098] In summary, and considering the upper limit of the pull-out force in Example 1, the magnetic attraction force is recommended to be between 0.45-11.5N, preferably 1.2-8N.

[0099] In addition to setting a reasonable suction force, the length of the interface component 12 and the pluggable external connector component 20 also needs to be considered. They are configured to be gripped by the middle, ring, and little fingers, allowing for one-handed operation. Otherwise, insufficient grip length may cause inconvenience for one-handed operation. Typically, based on the average adult finger width, the grip length can be set to no less than 4.5mm. If a magnetic suction solution is used, the feel is even better when rubbing with one hand, as the friction is almost zero during rubbing.

[0100] If both the interface assembly 12 and the pluggable external connector assembly 20 meet the requirement of a length of not less than 4.5mm, they can be opened with one hand from either direction. That is, they can be opened with one hand in both directions: one side can be pinched with the thumb and forefinger, and the other three fingers can be used to hold the other side, and then they can be opened by rubbing. The specific length is not limited, and the actual length depends on whether it is possible to open with one hand in both directions.

[0101] The interface assembly also includes a guide cavity 16. A pluggable external connector assembly can be inserted from the open end of the interface assembly and moved along the guide cavity 16 until it is attracted and positioned by the magnetic base 50. The magnetic pole direction of the permanent magnet 52 in the magnetic base 12 is parallel to the length direction of the guide cavity 16. The permanent magnet 52 is at least partially embedded in the base inside the interface assembly body or bonded to the base inside the interface assembly body. At least one end face of the permanent magnet faces the open end, and the end face facing the open end is a magnetic attraction surface for attracting the external connector. The direction of the attraction force is parallel to the guiding direction of the guide cavity 16. The length of the temple interface assembly is configured to be able to be held by the middle, ring, and little fingers. Thus, the interface is configured to be able to be pulled apart and retracted by a single hand in a straight line with minimal sidewall friction. This achieves a stable connection between the pluggable external connector assembly and the interface assembly, with near-zero resistance during insertion and near-zero friction during removal. The guide cavity 16 has a square or flat cross-section in at least a portion of its length direction. This square or flat cross-section primarily constrains the rotational freedom of the pluggable external connector assembly around the insertion / removal axis. The dominant forces during insertion and removal are magnetic attraction and magnetic restoring force. The cavity sidewalls mainly serve as guides and limiters, providing further constraint forces on top of automatic static stability, preventing the permanent magnets 52 in the magnetic base 50 and magnetic head 51 from disengaging or falling off, thus achieving passive stability during dynamic operation. Since mechanical clamping constraint is not required during static operation, the resulting frictional force is much smaller than the magnetic attraction force, ensuring smooth insertion and removal. Furthermore, because the magnetic poles of the permanent magnets are mainly parallel to the length direction of the guide cavity 16, the connector assembly only undergoes linear motion and not rotational motion during insertion. Therefore, the pluggable earpiece support leg is configured to cooperate with the external connector to achieve smooth, repetitive linear insertion and removal by hand, with minimal need to overcome sidewall friction and limiting wobbling or swinging during insertion and removal.

[0102] The phrase "basically no need to overcome sidewall friction" and the phrases "approaching zero resistance" and "approaching zero friction" mentioned elsewhere in the text refer to the fact that the sidewall does not participate in positioning and limiting functions. Therefore, the friction on the sidewall is neither utilized nor overcome. The aim is to minimize the sidewall friction during insertion and removal. Its main guiding and static stabilizing functions are accomplished by the magnetic centering effect without relying on the sidewall. It does not mean that there is an absolute requirement for no resistance or no friction, and it does not exclude the possibility of scraping or touching the sidewall or even full contact during insertion and removal.

[0103] The distance for the external connector to move within the guide cavity is less than 10mm. This distance allows for operation with a single hand rubbing; if it were too long, it would be difficult to pull out with one hand. The length of the detachable earpiece temple and the length of the front temple are both configured to be gripped by the middle, ring, and little fingers, thus enabling the detachable temple to be pulled out in a straight line with one hand from both directions.

[0104] The magnetic suction head is made of N42-N55 grade neodymium iron boron high magnetic energy product material. Its size, magnetization direction and layout are configured to generate an axial attraction force of 0.45-11.5N with the magnetic suction head of the external connector.

[0105] In one specific example, the magnetic suction head 51 is made of N52 grade neodymium iron boron high energy product material; its size, magnetization direction, and layout are configured to generate an axial attraction force of 1.2-8N with the magnetic suction head of the external connector; the magnetic suction head is cylindrical, with a length of 4-6mm, preferably 5mm, of which 1-2mm, preferably 1.5mm, is embedded in the connector assembly body, and 2-5mm, preferably 3.5mm, is exposed, with a diameter of 2-4mm, preferably 3mm; its exposed end face is the attraction surface. The connector assembly body has a square or flat cross-section in at least a portion of its length direction, matching the guide cavity. Figure 16 The corresponding dimensions were selected.

[0106] The polarity matching of the permanent magnets 52 in the magnetic base 50 and the magnetic head 51 should ensure that they attract rather than repel each other. That is, according to the principle of "like poles repel and unlike poles attract", the polarization directions of the two permanent magnets 52 at the attraction surface should be opposite, i.e., one is N and the other is S.

[0107] Because the static multi-degree-of-freedom automatic stabilization is achieved by utilizing the centering effect, the restoring force correction formed by the magnetic field gradient force, and the magnetic moment constraint under axial rotation, the permanent magnets 52 in the magnetic chuck 50 and magnetic chuck 51 can withstand vibrations and impacts of a certain intensity after they are attracted together. Therefore, it is not necessary to provide overly tight mechanical constraints, especially at the attraction surfaces of the two permanent magnets. When the vibration or impact is too great and exceeds the multi-degree-of-freedom stabilization mechanism provided by the magnetic force, the mechanical structures such as the base and guide cavity provide further constraint forces (as described above) to prevent the permanent magnets 52 in the magnetic chuck 50 and magnetic chuck 51 from disengaging or falling off, thus achieving passive stabilization in dynamic conditions. Since this stabilization is formed by being constrained by the external constraint structure after deviating from static stability, it is called dynamic passive stabilization. This dynamic passive stabilization mechanism is also suitable for ensuring stable insertion.

[0108] The advantages of this dual active and passive stabilization mechanism are as follows: Due to the presence of multi-degree-of-freedom automatic stabilization, there is no need for overly tightly integrated stabilizing mechanical structures on the cavity sidewalls, such as friction structures or clamping mechanisms. Thus, the dominant forces during insertion and removal are magnetic attraction and magnetic restoring force, with the cavity sidewalls primarily serving a guiding and limiting function. The frictional force generated is far less than the magnetic attraction force, ensuring smoother manual insertion and removal operations. On the other hand, the dynamic passive stabilization mechanism prevents the connector assembly and interface components from disengaging or falling off. Furthermore, the base, guide cavity, and other mechanical structures provide further constraint, allowing the product to adapt to hand tremors, shaking, and alignment deviations during insertion, thereby achieving high insertion reliability. This resolves the contradiction between stability / reliability and operational smoothness in existing technologies.

[0109] If a multi-pole array is used, the N and S poles must be arranged alternately, rather than a single pole pair. This design can form a closed magnetic circuit, enhancing the adsorption force and expanding the effective adsorption range. However, it increases the difficulty of production.

[0110] Magnetic materials (such as electrical pure iron) can also be added to the magnetic base 50 and the magnetic head 51 to guide the magnetic field distribution, reduce magnetic leakage, and improve the effective adsorption force.

[0111] Although magnetic connections are generally susceptible to interference from strong magnetic fields, the strength of the permanent magnets and their placement in this solution have been taken into account for everyday use environments, thus typically avoiding such problems. If the situation exceeds the limits of everyday use or requires enhanced anti-interference capabilities, this embodiment allows for the addition of mitigation measures, such as applying soft magnetic shielding material to the non-contact surfaces.

[0112] The interface method in this application is not limited to the card head 6, positioning bead 5, or magnetic attraction; it can also be a pin, thread, or other structures. The magnetic attraction structure in Embodiment 3 is preferred. The magnetic attraction structure is the only structure that uses end-face positioning. Its advantages include a large end-face contact area, tight face-to-face contact between the magnetic base and the magnetic head, and multi-degree-of-freedom automatic stabilization, making it less prone to shaking and wobbling. Furthermore, it does not require frictional force for connection during insertion and virtually eliminates the need to overcome friction during removal, thus reducing wear and increasing the number of insertions and removals. The side of the plug only serves as a guide, further assisting in reducing shaking and wobbling. Existing connection solutions either require excessive insertion force, causing wear during removal, or lack stability. Therefore, increasing stability and reducing insertion force are contradictory in existing connection solutions. This application cleverly solves this contradiction.

[0113] Other embodiments of this application also employ a positioning method on the side of the plug, such as positioning pins or clips, which are secured to the side of the connector rather than the end face. These methods also suffer from the same drawbacks: if too loose, they cannot prevent the plug from shaking or wobbling; if too tight, they are difficult to remove. Furthermore, relying on friction for positioning leads to wear after repeated insertions and removals, causing the plug to gradually shake or wobble even if there is no initial shaking or wobbling. This can easily lead to a "crooked leg" phenomenon caused by shaking or wobbling at the interface and connector when removing glasses with one hand. Embodiment 3 solves this problem.

[0114] like Figure 17 The image shown is a schematic diagram of the glasses when using a magnetic connector in this embodiment. Figure 18 This refers to the case where the connector assembly is installed in the charging case. There are two types of connector assemblies: one with electronic components (made in the form of an earphone) and one without electronic components. Figure 19 This refers to the case where the connector assembly is installed in the charging case. There is only one type of connector assembly, which is equipped with electronic components (earphone type).

[0115] like Figure 21 and Figure 22 The diagram shown is an assembly diagram of the eye socket component and the pluggable earpiece leg of the wireless charging smart glasses according to Embodiment 3 of the present invention. The pluggable earpiece leg includes an audio device 15, a charging contact 62 for charging, a microphone 60 with a receiving function, and a touch area 61 for touch control.

[0116] The pluggable ear-mounted temples and head-mounted smart devices proposed in various embodiments of the present invention, by opening a first opening in the outer shell of the pluggable ear-mounted temples and providing positioning and limiting components in a first cavity communicating with the first opening, can be adapted to pluggable external connector assemblies. This enables a quick, reusable pluggable structure between the front frame and temples of ordinary glasses, thereby promoting the separate production of the front frame and temples. It also promotes the mass and systematic production of ordinary glasses combined with smart glasses temples according to the standard of reusable pluggable technology. This not only effectively improves the production efficiency and large-scale application of smart glasses, but also allows for arbitrary adaptation to various models of front frames and temples produced according to the reusable pluggable standard, achieving a high degree of interchangeability, saving social resources, and reducing the economic burden on consumers. In particular, it provides a more convenient solution for people with myopia, hyperopia, or other vision problems to upgrade their ordinary glasses to smart glasses. This not only significantly reduces the physical and psychological discomfort caused by replacing the entire set of glasses, but also maintains the appearance of ordinary glasses chosen by consumers according to their own taste to the greatest extent, which is conducive to expanding the smart application upgrade of ordinary glasses.

[0117] In other embodiments, the detachable earpiece legs can also be used in other head-mounted smart devices, such as smart helmets, AR headsets, and headphones. The detachable earpiece legs of this invention improve the convenience and versatility of head-mounted smart device production and replacement, and facilitate interoperability between manufacturers.

[0118] The pluggable earpiece temple in this application has an interface component, allowing it to connect to an eyeglasses-style frame with a connector component. This eyeglasses-style frame is essentially half of an eyeglass temple. Therefore, the pluggable earpiece temple can be used as a universal component for connecting eyeglasses temples, compatible with various types of eyeglasses. This gives it strong versatility, creating a completely new product category, which can be called "Universal Eyeglasses Connector," meaning "compatible with all types of eyeglasses"; or "Ear-Ear Connector," or "Ear-Ear Connector." Because it has an earphone function and can also be used as part of an eyeglass temple, it can also be called "Ear-Ear Connector." The eyeglass portion, being only half an eyeglass temple and having an additional connector device compared to ordinary eyeglass temples, remains a completely new product category and can be called "Universal Ear Connector," meaning "compatible with all types of earphones"; or "Ear-Connecting Eyeglasses," meaning "eyeglasses connected to earphones"; or simply "Ear Mirror," "Ear Glasses," or "Eye-Ear Mirror."
