Description

Technical Field

[0001] The present invention relates to the technical field of head-mounted devices, and in particular to a detachable earpiece support leg and a head-mounted smart device. Background Art

[0002] The front frames and temples of existing ordinary glasses are usually fixed and non-detachable, forming a single unit. Existing smart glasses and smart AI glasses also typically have a single-piece design with the front frames and temples. These are typically manufactured by the same manufacturer, lacking a standard interface. Disassembly, replacement, and scalability are poor, making them particularly inconvenient for people with myopia. The specific structure of current glasses is not conducive to the upgrade and iteration of smart AI glasses. Upgrading to smart AI glasses requires purchasing a separate set of products and matching lenses, which increases costs.

[0003] Some improved smart glasses keep the front frame fixed and replace the entire temple. The front frame and temple can be separated by removing screws, plugging or buckling. However, this method still has the following defects: (1) From the perspective of production technology, the production method of separating the front frame and temple is highly specific and poorly matched, which not only reduces the compatibility between components, 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 forced to be idle. This inseparable replacement model not only increases the economic burden on consumers, but also causes a large amount of unnecessary loss of social resources.

It does not necessarily belong to the prior art of this patent application. In the absence of clear evidence that the above content has been disclosed on the filing date of this patent application, the above background technology should not be used to evaluate the novelty and creativity of this application.

[0016] The attraction surface of the magnetic seat is a positioning surface, which is perpendicular to the insertion path direction; thus, the detachable earpiece leg is configured to cooperate with the external connector to achieve a linear plug-in connection that can be repeatedly inserted and removed by rubbing with one hand without overcoming the side wall friction.

[0044] Compared with the prior art, the beneficial effects of the present invention are: the detachable earpendant leg disclosed in the present invention is used to be connected to the pluggable external connector assembly in a removable manner by hand, and a positioning component and a limiting component are arranged in the first cavity in the shell that is connected to the first opening to form a stable connection structure with the pluggable external connector assembly, so that the detachable earpendant leg can form a quick-plug and removable structure by hand between the detachable earpendant leg and the pluggable external connector assembly, and a standardized interface design of the earpendant leg that can be removable by hand is realized, which can improve interchangeability to be compatible with multiple types of frames and reduce production complexity, thereby solving the technical problems of existing smart glasses legs and other head-mounted smart devices that are inconvenient to disassemble, high production costs and low resource utilization; consumers no longer have the difficulty of choosing whether to wear ordinary glasses or smart glasses when going out, but only need to carry an accessory similar to an "earphone charging case" that contains the removable temple interface assembly of the present application.

[0045] In a further embodiment, the present invention also has the following beneficial effects:

[0046] (1) By arranging the positioning component on the inner side wall or the limiting component in the direction of the path in which the housing is inserted from the first opening, it is convenient for the user to repeatedly insert, remove and disassemble the housing by hand.

[0047] (2) When the positioning component is a positioning bead or a clamp, at least two positioning beads or clamps can be provided on opposite inner walls of the first cavity to enhance the connection stability between the pluggable external connector assembly and the detachable earpiece leg.

[0048] (3) A plurality of positioning beads or clamps of different sizes are arranged in the direction of the path of insertion of the first end of the pluggable external connector assembly from the first opening. On the one hand, they can adapt to pluggable external connector assemblies of different sizes, and on the other hand, they can also adjust the length of the overall earpiece leg.

[0049] (4) When the positioning component is a magnetic seat, the positioning component and the position setting of the limiting component of the present application, as well as the setting of the guide cavity, determine that the plugging and unplugging is done forward and backward, without the need for rotation operation, and without swinging or shaking during operation; combined with the design of the appropriate plugging and unplugging force and the design of the plug moving distance during plugging and unplugging, an average adult can "rub open" the connection between the interface and the connector in a straight line with one hand during disassembly (the thumb and index finger pinch the front end, the other three fingers hold the back end, and use the pinching friction of the thumb and index finger to push forward with force), thus avoiding the problem of glasses being damaged or thrown off due to excessive force during two-handed operation. Since there is no need to overcome the friction of the side wall, wear can be reduced and more plugging and unplugging times can be achieved.

[0050] (5) This application uses the ear bend (bend) as the boundary, with the rear speaker and the front sound outlet. The speaker and the sound outlet are not adjacent to each other, but are connected through a sound guide channel. On the one hand, the sound quality is improved by the reflection and resonance of the sound in the sound guide channel. On the other hand, it greatly explains the position limitation of the speaker and makes valuable design space for the interface component. The sound outlet is directed to the inner side of the wearer's auricle. In this way, most of the sound emitted is collected and directed by the auricle, which not only does not affect the sound quality, but also does not cause interference to people nearby. This solves the contradiction that earplugs make people feel impolite while playing sound outside affects others.

[0051] Other beneficial effects of the embodiments of the present invention will be further described below. BRIEF DESCRIPTION OF THE DRAWINGS

[0073] The following is a detailed description of the embodiments of the present invention. It should be emphasized that the following description is only exemplary and is not intended to limit the scope of the present invention and its application.

[0074] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element. In addition, the term "connected" can be used for both fixing and circuit / signal communication.

[0075] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and 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, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0076] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0077] It is worth noting that the “front” and “rear” mentioned in this application are distinguished along the length direction of the shell.

[0078] like Figure 1 and Figure 2As shown, a preferred embodiment of the present invention is a detachable earpiece leg 10, which is used to be connected to a pluggable external connector assembly 20 by being repeatedly detachable by hand, and includes a shell 11 and an interface assembly 12, wherein the shell has an ear bend portion for matching with the wearer's auricle; a first opening portion 111 is provided at a first end of the shell 11, and the interface assembly 12 includes a positioning component 121 and a limiting component 122, both of which are arranged in a first cavity 112 in the shell 11 that is connected to the first opening portion 111, and the positioning component is used to position the connector in the pluggable external connector assembly; the limiting component 122 is arranged away from the positioning component 121 Or a side close to the first opening portion 111 is used to limit the pluggable external connector, limit the insertion depth of the external connector after breaking through the positioning of the positioning component during insertion, or limit the positioning component to limit the degree of rearward movement of the positioning component caused by the impact of the external connector insertion; thereby, the connector end of the pluggable external connector assembly 20 can be simultaneously adapted to the positioning component 121 and the limiting component 122 after being inserted from the first opening portion 111; a second cavity is provided at one end of the shell away from the first opening portion, and an electronic module is also provided in the second cavity; thereby, the electronic module can be repeatedly removed and worn on the ear by hand through the shell and the interface assembly.

[0079] The detachable earpendant leg 10 is, for example, a detachable back leg of glasses, the outer shell 11 is a shell, the first opening 111 corresponds to an opening, and the first end of the pluggable external connector assembly 20 is, for example, the front temple 2 of the external glasses frame 1, and a positioning recess is provided on the front temple for snapping and connecting with the positioning component 121.

[0080] The positioning component 121 is provided on the inner wall of the first cavity 112 in the direction of the path along which the first end of the pluggable external connector assembly 20 is inserted from the first opening 111 .

[0081] refer to Figure 2 and Figure 3In some embodiments, the positioning component 121 is a positioning bead 121A, which is protruded from the inner wall of the first cavity 112. The positioning bead 121A is a spherical elastic protrusion or a hemispherical elastic protrusion. When the positioning bead 121A is a spherical elastic protrusion, the lower hemispherical shape is elastically embedded in the inner wall of the first cavity 112, and the upper hemispherical shape is protruded from the inner wall of the first cavity 112. When the positioning bead 121A is a hemispherical elastic protrusion, an elastic component can be provided below the hemispherical structure to directly form 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 elastic force of the positioning bead is 8N to 12N. The anti-slip layer has a surface corrugated texture, for example. In other embodiments, a layer of flexible material with a Shore hardness of 20A to 50A may be provided on the surface of the positioning bead 121A to provide an anti-slip effect. Figure 4 and Figure 5 In other embodiments, the positioning component 121 is a clamping head 121B, which is also protruded from the inner wall of the first cavity 112, wherein the clamping head 121B is a boss-shaped elastic protrusion.

[0082] refer to Figure 2 and Figure 4 In some embodiments, the number of the positioning bead 121A or the clamp 121B is one, which is protruded on the lower side wall or the upper side wall of the first cavity 112. Figure 3 and Figure 5 In some embodiments, the number of positioning beads 121A or clamps 121B is two, and the two positioning beads 121A or clamps 121B are relatively arranged on the inner wall of the first cavity 112, for example, the two positioning beads 121A or clamps 121B are relatively protruded on the upper side wall and the lower side wall, or relatively protruded on the left side wall and the right side wall. In other embodiments, the number of positioning beads 121A or clamps 121B can be three or even more, and multiple positioning beads 121A or clamps 121B can be relatively arranged on the inner wall of the first cavity 112, or can be arranged on the inner wall of the first cavity 112 along the path direction of the first end of the pluggable external connector assembly 20 inserted from the first opening portion 111, so that the distance between each positioning bead 121A or clamp 121B and the first opening portion 111 is different, and the overall length of the earpendant leg can be adjusted. In addition, the size of each positioning bead 121A or clamp 121B can also be different to accommodate pluggable external connector assemblies 20 of different sizes.

[0083] In some other embodiments, the positioning component 121 can be a pin, a thread, a magnetic part or other structures in addition to the positioning bead 121A or the clamp 121B. Correspondingly, the adapter structure provided in the pluggable external connector assembly 20 is also adjusted accordingly according to the positioning component 121.

[0084] refer to Figure 2 The limiting component 122 is a limiting baffle provided in the first cavity 112 on the side away from the first opening 111, and the limiting baffle is perpendicular to the path direction of the first end of the pluggable external connector assembly 20 inserted from the first opening 111, and the distance between the limiting baffle and the positioning component 121 is equal to the distance between the first end of the pluggable external connector assembly 20 and the corresponding groove, so that after the first end of the pluggable external connector assembly 20 is inserted from the first opening 111, the end of its first end can be blocked by the limiting baffle to achieve the limiting effect.

[0085] In some embodiments, the distance between the interface component 12 and the end of the housing 11 away from the first opening 111 is 8 cm to 13 cm, or the entire length of the housing 11 is 8 cm to 13 cm.

[0086] refer to Figure 6 The pluggable external connector assembly 20 includes a bracket body 21 and a connector 22. A recessed portion is provided on the sidewall of the bracket body 21 near the first end. The recessed portion forms the connector 22. When the first end of the bracket body 21 is inserted into the housing 11 through the first opening 111, the connector 22 mates with the positioning member 121, and the end of the first end of the bracket body 21 mates with the stop member 122. The recessed portion forming the connector 22 can accommodate the positioning bead 121A or the clamp 121B that constitutes the positioning member 121. The end of the first end of the bracket body 21 abuts against the stop member 122, forming a stable connection. The size of the first opening 111 matches the size of the first end of the bracket 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 bracket body 21, or there is a clearance fit between the two. This further ensures a secure connection between the detachable earpiece leg 10 and the pluggable external connector assembly 20, and restricts the first end of the pluggable external connector assembly 20 from shaking within the first cavity 112 through the housing 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 temple end of the eyeglass frame.

[0087] refer to Figure 7 and Figure 8 In some embodiments, the detachable earpiece leg further includes an electronic module. A second cavity 113 is provided at one end of the housing 11 away from the first opening 111, and the electronic module is disposed in the second cavity 113. Figure 9 The shell 11 is provided with a bending portion 114, and the bending portion 114 is provided at a position above the shell 11 corresponding to the wearer's auricle 30, the first cavity 112 is provided in the shell 11 at a position corresponding to the front of the wearer's auricle, and the second cavity 113 is provided in the shell 11 at a position corresponding to the back of the wearer's auricle 30. Such a design can place electronic modules with larger volume or weight behind the auricle 30, effectively utilize the internal space of the detachable ear wear leg 10, reduce the weight in front of the bending portion 114 (in front of the auricle), balance the pressure of the front structure of the head-mounted smart device on the bridge of the nose and the pressure of the detachable ear support 10 on the auricle 30, and improve wearing comfort. For example, in a specific example, a bending portion 114 is provided on the shell, the first cavity 112 is provided at the front end of the bending portion 114, and the second cavity 113 is provided at the rear end of the bending portion 114.

[0088] The housing 11 is provided with a charging port connected 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 is provided with a power interface, which 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 wireless WIFI module. For example, the housing is provided with a charging port connected to the second cavity 113, and the charging port is connected to the power supply.

[0089] In some embodiments, the detachable earpiece leg further includes an audio device 15. A third cavity 115 is provided within the housing 11 between the second cavity 113 and the first cavity 112. A sound outlet 116 is provided on the housing 11, communicating with the third cavity 115. The audio device 15 is disposed within the third cavity 115 or the second cavity 112. In this embodiment, the sound outlet 116 is provided on the housing 11 at a position corresponding to the front of the wearer's auricle 30 (e.g., at the temple), with the sound output of the sound outlet directed toward the inner side of the wearer's auricle. The audio device 15 is disposed within the housing 11 at a position corresponding to the rear of the wearer's auricle 30 within the second cavity 112 or the third cavity 115. A sound guide channel is provided within the third cavity 115, communicating with the sound outlet 116 through the sound guide channel. The audio device 15 may be, but is not limited to, a speaker or a miniature speaker. By placing the audio device 15 at the rear, separating it from the sound outlet 116, the audio device 15 is connected to the sound outlet 116 via 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. Thus, since the audio device 15 is located away from the sound outlet 116, the sound does not directly exit the sound outlet 116 immediately after being emitted, but must first pass through the sound guide channel. This not only makes the position design of the sound outlet 116 and the audio device 15 more flexible, but also provides space for sound quality design. The special design of the sound guide channel allows the sound to reverberate and resonate within the cavity, improving the 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 0.5 mm to 2 mm. In a specific example, the sound outlet 116 is arranged on the shell near the front end of the third cavity 115; the audio device 15 is arranged near the rear end of the third cavity 115 or near the third cavity 115 in the second cavity 112; the audio device 15 is connected to the sound outlet 116 through the sound transmission channel (i.e., the sound guide channel) in the third cavity 115.

[0090] In some embodiments, the outer shell 11 may be, but is not limited to, plastic titanium, which has the advantages of being ultra-light, impact-resistant, high-temperature resistant (can withstand temperatures of 110°C), and highly elastic. The outer shell 11 may also be made of a silicone material, which has the advantages of being highly elastic and aging-resistant, such as thermoplastic rubber (TPR) or thermoplastic elastomer (TPE). Furthermore, at least a portion of the outer wall of the outer shell 11 is provided with a layer of flexible material, elastic material, or magnetic material. This flexible material layer, such as plastic, can enhance the comfort of the temples.

[0091] refer to Figures 10 to 12Another preferred embodiment of the present invention discloses a pair of smart glasses, comprising an eye socket component 40 (i.e., a frame), a pluggable external connector assembly 20 (i.e., a front temple), and a detachable earpiece leg 10 (i.e., a detachable temple). The second end of the pluggable external connector assembly 20 is fixedly connected to the eye socket component 40 (e.g., fixedly connected by screws). The detachable earpiece leg 10 and the pluggable external connector assembly 20 are adapted to be combined to form an integral temple portion of the glasses. The detachable earpiece leg 10 is equivalent to the rear temple portion of the glasses, and the pluggable external connector assembly 20 is equivalent to the front temple portion of the glasses. The housing 11 of the detachable earpiece leg 10 can be a plastic housing or a metal housing. 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 front temples) constitute the eyeglass frame portion, one end of the front temple is connected to the frame, and the other end of the front temple is inserted into the opening of the detachable temple, and the positioning recess set on the front temple is engaged with the positioning component.

[0092] The length of the detachable earpiece leg 10 can be less than or equal to 1 / 2 of the total length of the temple of the glasses, for example, 1 / 3, or the length of the detachable earpiece leg 10 can be the 8 cm to 13 cm portion of the tail of the temple of the glasses. For example, in a specific embodiment, the length of the detachable temple is 1 / 2 to 1 / 4 of the length of the entire pair of glasses.

[0093] The front end of the shell 11 of the detachable earpendant leg 10 provided in the preferred embodiment of the present invention is provided with a first opening portion 111 and a first cavity 112, and a limiting component 121 is provided in the first cavity 112. For the manufacturer, it is only necessary to drill a hole or open a limiting groove (collectively referred to as "positioning groove") on the front leg of the temple of an ordinary frame, so that it can be docked with the detachable earpendant leg 10 (the rear leg part of the temple) of the present application; for the user, when upgrading to smart glasses, there is no need to buy a whole pair of glasses, only the rear leg part of the temple (that is, the detachable earpendant leg 10) is needed. When replacing the lens, there is also no need to buy a whole pair of glasses, and the frame can be docked with the temple of the present application; it is more convenient for both the manufacturer and the user, and improves the convenience and compatibility of the production and replacement of glasses. In addition, the present invention also provides a limiting component 122 at the end of the first cavity 112 away from the opening. After the front leg part of the temple on the frame (that is, the pluggable external connector assembly 20) passes through the first opening 111, it can be matched with the positioning component 121 more quickly through the limitation of the limiting component 122, thereby achieving rapid fixation and further improving the convenience of use.

[0094] All the electronic components in this embodiment are located in the housing 11 of the detachable earpend leg 10, while the pluggable external connector assembly 20 does not have any electronic components. This makes it very easy for glasses manufacturers to produce, allowing a large number of glasses manufacturers to enter the smart glasses market simply by setting connectors, greatly enriching the styles of smart glasses. On the other hand, smart wearable device manufacturers do not need to consider the production process and style of glasses. They only need to keep one interface assembly to adapt to thousands of types of glasses. The pluggable external connector assembly and the interface assembly form a standard connection, which is very conducive to standardized large-scale production.

[0095] The embodiment of the present invention optimizes the layout of the core components of smart glasses by integrating the electronic components 13, power supply 14, audio device 15 and other large components (refer to Figure 7 and Figure 8 ), making full use of the space at the back of the temples, effectively solving the problem of idle space at the contact point between the temples and 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.

[0096] Figures 10 to 12 The figure shows a pair of smart glasses with quick-detachable temples. The principle is to improve on the basis of conventional glasses so that the temples can be repeatedly detached by hand. After being disassembled, they become the separately saleable front temples (corresponding to the aforementioned pluggable external connector assembly 20) and rear temples (corresponding to the aforementioned detachable ear-worn temples 10), which become a whole after being plugged in. Among them, the rear temples have built-in functional modules (such as audio devices) or electronic modules. The front temples may or may not contain functional modules or electronic modules. The situation in which the front temples and rear temples of the glasses become a whole after being plugged in is shown in FIG. Figure 10 As shown, the state where the front legs and the back legs of the glasses are separated is as follows Figure 11 As shown, the front frame of the glasses is separated from the front legs and the back legs of the glasses. Figure 12 shown.

[0097] The back legs of the glasses can be ordinary plastic legs, or they can be made of special materials such as silicone rubber, antibacterial materials, titanium alloys, silver-containing materials, expensive metals or jewelry to increase their comfort, antibacterial properties or sense of nobility (so people tend to replace the front legs and keep the back legs); the back legs can also be different fashionable fast-moving consumer goods styles to enhance the sense of fashion (so people tend to replace the back legs and keep the front legs); the back legs can also be only partially removed; all functional modules are located in the detachable part, so that the other part can still be hung on the ear after removal without affecting the wearing of glasses.

[0098] The design principle of the embodiment of the present invention is based on existing ordinary glasses. Its front frame and front temple (front end of the temple) are still integrated and the basic structure of the original glasses is maintained as much as possible. However, the interface component 8cm to 13cm away from the back temple (end of the temple) is designed as a detachable section to connect with the smart glasses temple module and the ordinary temple module that can be quickly detached. The front temple corresponds to the pluggable external connector assembly 20, and the back temple corresponds to the detachable earpiece support leg 10. The two are connected by a special docking method, including but not limited to, for example, a clamp (the length and width of the clamp are 2mm to 4mm, and the clamping force is 8N to 12N; preferably, it is 3.0mm long * 3.0mm wide * 1.5mm high, and the clamping force is 10N), a positioning bead (the main body diameter of the positioning bead is 2mm to 4mm, the elastic force is 8N to 12N, preferably, the main body diameter of the positioning bead is 3mm, and the elastic force is 10N), a pin, a thread, etc., and the temple and front frame are integrated into a whole, so that the smart glasses can be switched between ordinary glasses. This docking method, which allows for quick and repeated manual removal from glasses, expands the intelligent application upgrades of ordinary glasses. It can be docked with AI smart modules, Bluetooth headsets, and audio modules to enhance their technological appeal. It can also be docked with ordinary plastic temples made of TR-90 (plastic titanium), which is ultra-light, impact-resistant, heat-resistant (can withstand temperatures of 110°C), and highly elastic. Silicone temples are made of TPR and TPE, which are highly elastic and age-resistant. Other special materials can also be used to enhance comfort.

[0099] like Figures 13 to 19 , is a schematic diagram of another embodiment of the present invention. Figure 14 It is an exploded schematic diagram of the interface structure (including connector components and interface components). Figure 15 The figure is a schematic diagram of an exploded view of glasses with detachable temples. Magnets 52 are provided inside the magnetic seat 50 and the magnetic head 51. The magnetic seat 50 includes a cylindrical or disc-shaped magnet embedded in or bonded to the limiting component 122. The magnetic seat 50 is provided on the limiting component 122. The engaging surface of the magnetic seat is a positioning surface, which is perpendicular to the insertion path direction. Thus, the detachable earpiece legs are configured to cooperate with the external connector to achieve a single-handed removable connection. In the detachable temple interface assembly of this embodiment, the interface structure adopts magnetic positioning, such as Figure 13 As shown, the interface assembly positioning component is a magnetic base 50, which cooperates with the magnetic head 51 provided on the connector to achieve positioning through attraction. The magnetic base has a magnetic force level between N42 and N55, preferably N52. The base is cylindrical and 4-6mm long, preferably 5mm long. It is embedded within the interface assembly body by 1-2mm, preferably 1.5mm, and exposed by 2-5mm, preferably 3.5mm. The diameter is 2-5mm, preferably 3mm. The exposed end surface is the engagement surface.

[0100] The guide cavity 16 has a square or flat cross-section along at least part of its length. This prevents the connector assembly from rotating during insertion. The detachable earpiece leg is thus configured to cooperate with the external connector to achieve a single-handed, reproducible, linear plug-in and pull-out connection, eliminating the need to overcome sidewall friction and limiting wobbling or swinging during insertion and removal.

[0101] The distance for the external connector to move in the guide cavity is less than 7 mm, and this distance can be achieved by rubbing with one hand.

[0102] The magnetic head 51 has a magnetic force rating between N42 and N55, preferably N52. It is cylindrical and 4-6 mm (preferably 5 mm) long, with 1-2 mm (preferably 1.5 mm) of it embedded within the connector assembly, leaving 2-5 mm (preferably 3.5 mm) exposed. It has a diameter of 2-4 mm (preferably 3 mm). The exposed end surface serves as the engaging surface. The connector assembly body has a square or flat cross-section along at least a portion of its length, matching the guide cavity. Figure 16 The corresponding dimensions are marked.

[0103] The interface method in this application is not limited to the clamp 6, positioning beads 5, and magnets; it can also be a pin, thread, or other structure. The magnetic structure is preferred. The magnetic structure is the only structure that uses end-face positioning. Its advantages are a large end-face engagement area, a close face-to-face fit between the magnetic base and the magnetic head, and a low risk of wobble and swing. It also eliminates the need for frictional connection during insertion and frictional resistance during removal, which reduces wear and increases the number of insertions and removals. The side of the plug only serves as a guide and further helps reduce wobble and swing. Other structures use side-face positioning, such as positioning posts and snaps that are located on the side of the connector rather than the end face. If too loose, the plug cannot be prevented from wobble or swing; if too tight, it is difficult to remove. Furthermore, relying on friction for positioning can cause wear after frequent insertions and removals. Even if there is no wobble or swing at first, it will gradually develop over time. Consequently, when removing glasses with one hand, the "twisting legs" phenomenon caused by wobble or swinging at the interface and connector can easily occur. This embodiment solves this problem.

[0104] like Figure 17 , which is a schematic diagram of the entire glasses when the magnetic connector is used in the present invention. Figure 18 This is the situation when 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 headphones) and the other without electronic components. Figure 19 This is the situation when the connector assembly is installed in the charging case. There is only one type of connector assembly, which is the one with electronic components (earphone form).

[0105] The detachable earpiece legs and head-mounted smart devices proposed in various embodiments of the present invention, by providing a first opening in the housing of the detachable earpiece legs and providing a positioning component and a limiting component within a first cavity communicating with the first opening, can be adapted to a pluggable external connector assembly, thereby enabling a manually removable structure for quickly plugging and unplugging the front frame and temples of ordinary glasses. This can promote the separate production of front frames and temples, and promote the mass and systematic production of ordinary glasses combined with smart temples according to the standard of manually removable detachability. 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 standard of manually removable detachability, 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, and other eyewear needs to upgrade from ordinary glasses to smart glasses. This not only significantly reduces the physical and psychological discomfort caused by replacing an entire set of glasses, but also maximizes the appearance of the ordinary glasses selected by consumers based on their own tastes, which is conducive to expanding the intelligent application upgrade of ordinary glasses.

[0106] In other embodiments, the detachable earpendant legs can also be used with other head-mounted smart devices, such as smart helmets, AR head-mounted display devices, headphones, etc. The detachable earpendant legs of the present invention can improve the convenience and versatility of production and replacement of head-mounted smart devices, and facilitate compatibility between manufacturers.

[0107] The detachable ear-worn support leg in the present application is provided with an interface component, so that it can be connected to a glasses-type bracket provided with a joint component, and the glasses-type bracket is actually half of the glasses leg; in this way, the detachable ear-worn support leg in the present application can be used as a universal component for connecting the glasses leg, and can be plugged into various different glasses, so it has strong versatility, forming a new category, which can be called "Wan'ertong", meaning "all kinds of glasses can be used universally"; or called "mirror-eartong", "ear-mirrortong"; because it has the function of headphones and can be used as part of the glasses leg, it can also be called "mirror-earphone"; and the glasses part is still a new category because it has only half of the glasses leg and has an additional joint device than ordinary glasses legs, so it can be called "Wan'ertong", meaning "all kinds of headphones can be used universally"; or called "tong'erjing", meaning "glasses connected to headphones"; it can also be called "otoscope" or "ear-glasses", "eye-otoscope".
