[0056] In a specific implementation, the battery bracket 1 includes a bracket body 11 for mounting the movable battery 3, and a bracket connection structure 12 for mounting the bracket body 11 onto the smart glasses, so as to facilitate the installation of the device.

[0057] Specifically, the bracket connection structure 12 can be a collar, through which the power supply device is sleeved onto the temple 42 of the smart glasses 4, which enables convenient installation of the device;

[0058] The bracket connection structure 12 can also be a hook, through which the power supply device can be attached to the frame 41 or temple 42 of the smart glasses, enabling convenient installation of the device;

[0059] The bracket connection structure 12 can also be a reusable adhesive, which can be used to attach the power supply device to the frame 41 or temple 42 of the smart glasses, thus enabling convenient installation of the device.

[0060] The bracket connection structure 12 can also be a magnetic component, which can be used to attach the power supply device to the smart glasses made of ferromagnetic metal, thus enabling convenient installation of the device.

[0061] The bracket connection structure 12 can also be a plug-in component, which can be an adaptable pin and slot. The slot can be opened in the frame of the smart glasses, more specifically in the frame 41 or the temple 42, and the pin is fixed to the bracket body 11. Alternatively, the pin can be fixed in the frame and the slot can be opened in the bracket body 11 to achieve a plug-in connection.

[0062] As a preferred embodiment, the battery holder 1 includes a detachable battery structure, through which the movable battery is detachably connected to the battery holder. The detachable battery structure is one of a detachable collar, a detachable hook, a detachable adhesive, or a detachable magnetic structure.

[0063] In practice, to facilitate the charging and discharging of the portable battery 3, the portable battery 3 and the battery bracket 1 can be designed as a detachable structure. When the portable battery 3 needs to be charged, it is only necessary to remove the portable battery 3 and charge it separately.

[0064] Specifically, the detachable battery structure can be a detachable collar, through which the movable battery is installed on the battery bracket, enabling convenient installation and removal of the movable battery;

[0065] The detachable battery structure can also be a detachable hook, which allows the movable battery to be installed on the battery holder, enabling convenient installation and removal of the movable battery.

The magnetic structure consists of magnets with opposite magnetic poles respectively located in the movable battery 3 and the holder body 11. For example, a connecting magnet is provided in the movable battery 3, and a battery connecting magnet is provided in the battery holder 1, with the opposing magnetic poles of the connecting magnet and the battery connecting magnet having opposite poles. Similarly, the movable battery 3 and the battery holder 1 can also have one being a magnet and the other a ferromagnetic material. Specifically, the types of magnets include, but are not limited to, samarium cobalt magnets, neodymium iron boron magnets, ferrite magnets, AlNiCo magnets, and iron-chromium-cobalt magnets, and the ferromagnetic materials include, but are not limited to, metals such as iron, cobalt, and nickel.

[0068] In this preferred embodiment, the connecting line 2 is provided with a connecting line terminal 21, and the smart glasses 4 is provided with a power interface. The connecting line 2 is electrically connected to the power interface of the smart glasses 4 through the connecting line terminal 21.

[0069] In practice, smart glasses, including but not limited to AR glasses, all have built-in non-removable batteries. When charging is required, a charger needs to be connected to the power interface of the smart glasses to charge them. These power interfaces are often pre-designed by the manufacturer. Therefore, it is only necessary to set the connector terminal 21 to a plug corresponding to these interfaces to easily connect to the smart glasses and transmit power.

[0070] In this preferred embodiment, the power interface is one of a Type-C interface, a micro USB interface, or a DC interface, and the connecting wire terminals are correspondingly provided Type-C plugs, micro USB plugs, or DC plugs.

[0071] In practice, a power interface can be provided on the frame or temple of the smart glasses, using one of the following: a Type-C interface, a micro USB interface, or a DC interface. The connecting cable terminals are the corresponding Type-C plug, micro USB plug, or DC plug, which can be used to match the charging port of the smart glasses, allowing users to easily connect and charge them.

[0072] In a preferred embodiment, the connecting wire terminal 21 is provided with a terminal conductive structure, the power interface includes an interface conductive structure, and the terminal conductive structure is electrically connected to the interface conductive structure.

[0073] In practical implementation, to further reduce the space occupied by the power interface on the smart glasses, the power interface needs to be designed to be more miniaturized and compact. The interface conductive structure includes a positive conductive metal sheet and a negative conductive metal sheet. Correspondingly, the terminal conductive structure includes a positive conductive element and a negative conductive element. When the connecting wire terminal is connected to the power interface, the positive conductive element of the connecting wire terminal is electrically connected to the positive conductive metal sheet of the power interface, and the negative conductive element of the connecting wire terminal is electrically connected to the negative conductive metal sheet of the power interface, thus realizing the electrical connection between the connecting wire terminal and the power interface. The positive and negative conductive elements can be elastic metal sheets, metal protrusions, or spring pins.

[0074] In a preferred embodiment, the connecting terminal 21 is provided with a terminal fixing structure, which is used to fix the terminal conductive structure at the power interface so that the terminal conductive structure is electrically connected to the interface conductive structure.

[0075] In practice, to ensure the stability and reliability of the electrical connection between the connector terminal and the power interface, the connector terminal is equipped with a terminal fixing structure, which can stably and reliably fix the connector terminal to the power interface.

[0076] As a preferred embodiment, the terminal fixing structure is a snap-fit ​​component or a magnetic component.

[0077] In specific implementation, taking the placement of the conductive interface structure on the frame beam as an example, to fix the connecting wire terminal to the frame beam, the connecting wire terminal has an "n"-shaped clip structure. By snapping the "n"-shaped clip structure connecting wire terminal 21 onto the frame beam of the smart glasses 4, the connecting wire 2 and the smart glasses 4 can be fixedly connected. When the connecting wire terminal is fixed to the frame beam, the positive conductive part of the connecting wire terminal is electrically connected to the positive conductive metal piece of the power interface, and the negative conductive part of the connecting wire terminal is electrically connected to the negative conductive metal piece of the power interface, thus achieving electrical connection.

[0078] To facilitate the expansion of the power supply device, the connecting terminal 21 is provided with two terminal conductive structures. One terminal conductive structure is electrically connected to the interface conductive structure of the smart glasses 4, and the other terminal conductive structure is electrically connected to the terminal conductive structure of another power supply device. This allows multiple power supply devices to be connected in parallel, thereby providing the smart glasses with a longer battery life and making it convenient for users to replace the removable batteries one by one.

[0079] Similarly, a magnetic connector can be provided at the power interface, and the terminal fixing structure can be a corresponding magnetic connector. Specifically, by providing a magnetic connector for connecting to the smart glasses and a conductive structure for electrical connection at the connector terminal 21, and by providing a magnet for connecting to the connector terminal 21 and a conductive structure for electrical connection at the power interface of the smart glasses, when the connector terminal 21 is magnetically attached to the power interface of the smart glasses, the conductive structure and the conductive structure are electrically connected. Alternatively, a magnet can be provided at the connector terminal 21, and a ferromagnetic material can be provided at the power interface to achieve the same magnetic connection effect, and vice versa.

[0080] To facilitate the expansion of the power supply device, the connecting cable 2 is equipped with two terminal conductive structures. One terminal conductive structure is electrically connected to the interface conductive structure of the smart glasses 4, and the other terminal conductive structure is electrically connected to the terminal conductive structure of another power supply device. This allows multiple power supply devices to be connected in parallel, thereby providing the smart glasses with a longer battery life and making it convenient for users to replace the removable batteries one by one.

[0081] In this preferred embodiment, each end of the connecting line 2 is provided with a battery bracket 1, and the battery bracket 1 is electrically connected to the power interface of the smart glasses through the connecting line terminal 21.

[0082] In practical implementation, the connecting wire terminal 21 is located in the middle of the connecting wire 2, and a battery bracket 1 is set at each end of the connecting wire 2. This allows the smart glasses 4 to be powered simultaneously by two movable batteries 3, and also enables the replacement of the movable batteries 3 without interrupting the power supply to the smart glasses 4. Correspondingly, the power interface of the smart glasses 4 is located in the middle of the frame 41, and the two battery brackets 1 are respectively set on the two temples 42, which helps the smart glasses 4 maintain balance and ensures the comfort of wearing the smart glasses 4.

[0083] To avoid the connecting cable 2 appearing obtrusive when mounted on the smart glasses 4, the connecting cable 2 can be a flexible FPC cable. Corresponding cable routing grooves are provided on the surfaces of the frame 41 and temples 42 of the smart glasses 4, ensuring that the connecting cable 2 does not protrude from the outer surface of the smart glasses 4 and maintaining an aesthetically pleasing appearance.

[0084] In a preferred embodiment, the smart glasses 4 include a frame 41 and temples 42, the battery holder 1 is connected to the temples 42, and the battery holder 1 is located behind the wearer's ear.

[0085] In practice, the balance of the smart glasses 4, which has a power supply device installed, can be adjusted by adjusting the position of the battery holder 1 on the temple 42. Preferably, connecting the battery holder 1 to the end of the temple 42 away from the frame 41 ensures the balance of the smart glasses 4 in the front-to-back direction. Simultaneously, the battery holder 1 is made of a flexible, non-slip material. When the battery holder 1 is placed against the back of the user's ear, it provides a limiting and anti-slip function for the smart glasses 4, ensuring the stability of the user wearing the smart glasses 4.

[0086] In a preferred embodiment, the battery holder is provided with a holder conductive connection structure, the movable battery is provided with a battery conductive connection structure, and the movable battery is electrically connected to the connecting line through the holder conductive connection structure.

[0087] In practical implementation, in order to facilitate the electrical connection between the movable battery and the battery holder, the battery holder is provided with a bracket conductive connection structure, and the movable battery is provided with a battery conductive connection structure. The movable battery is electrically connected to the connecting wire through the bracket conductive connection structure. The bracket conductive connection structure and the battery conductive connection structure can be adapted contact connectors or adapted plug-in connectors.

[0088] In this preferred embodiment, the conductive connection structure of the bracket and the conductive connection structure of the battery are compatible contact connectors, and the contact connectors are disposed on the side of the battery bracket that is in contact with the movable battery.

[0089] In practical implementation, the conductive connection structure of the battery bracket can be set as a POGOPIN connector, and the conductive connection structure of the battery can be set as a metal contact. When the removable battery is installed in the battery bracket, electrical connection is achieved through the POGOPIN connector and the metal contact, ensuring the electrical performance and connection reliability between the battery bracket and the removable battery. The reverse is also true.

[0090] In this preferred embodiment, the conductive connection structure of the bracket is a group of conductive sheets, and the conductive connection structure of the battery is a group of metal bumps; or the conductive connection structure of the bracket is a group of metal bumps, and the conductive connection structure of the battery is a group of conductive sheets.

[0091] In practical implementation, the conductive connection structure of the battery bracket can be set as a group of conductive plates, and the conductive connection structure of the battery can be set as a group of metal bumps. Specifically, the group of metal bumps can be a pair of metal bumps, which respectively form the positive and negative terminals of the movable battery. When the movable battery is installed in the battery bracket, electrical connection is achieved through contact between the group of metal bumps and the group of conductive plates. Specifically, the group of conductive plates can be conductive metal sheets, which are located on the bracket body. When the movable battery is installed on the bracket body, a pair of metal contacts are electrically connected to the conductive metal sheets, ensuring the electrical performance and connection reliability between the battery bracket and the movable battery. Similarly, setting the conductive connection structure of the bracket as a group of metal bumps and the conductive connection structure of the battery as a group of conductive plates can achieve the same electrical connection effect.

[0092] In a preferred embodiment, the bracket body is provided with a accommodating space for accommodating a movable battery. The movable battery can be installed in the accommodating space. The accommodating space is one of a groove, accommodating cavity, hole or notch, and the external structure of the movable battery is adapted to the shape structure of the accommodating space.

[0093] In practice, the support body is processed to form grooves, accommodating cavities, holes, or notches to accommodate the movable battery.

[0094] The external structure of the movable battery is adapted to the shape of the accommodating space.

[0095] The following explanation uses a circular groove as the accommodating space of the battery holder and a flat, round removable battery similar to a Go piece as an example. The circular groove can accommodate the lower half of the removable battery. A ring-shaped support magnet is set in the circular groove, and a ring-shaped connecting magnet is set in the removable battery. The opposing sides of the support magnet and the connecting magnet have opposite magnetic properties, so the removable battery can be connected to the battery holder by magnetic attraction, and the removable battery is confined in the circular groove of the battery holder. A circular conductive contact and an annular conductive contact are provided at the physical center of the bottom of the flat, oval-shaped removable battery. A first conductive spring pin / first metal protrusion is provided at the bottom of the circular groove of the battery holder, corresponding to the circular conductive contact, and a second conductive spring pin / second metal protrusion is provided at the bottom of the annular conductive contact. When the removable battery is installed on the battery holder, the first conductive spring pin / first metal protrusion is electrically connected to the circular conductive contact, and the second conductive spring pin / second metal protrusion is electrically connected to the annular conductive contact. The correct electrical connection can be achieved regardless of how the removable battery is rotated, thereby ensuring the reliability and stability of the electrical connection between the removable battery and the battery holder.

[0096] Please see Figures 5 to 7 This utility model also relates to a charging device for charging a portable battery of a power supply device for smart glasses, including a housing 5, a main control board 6 and a rechargeable battery 7. The main control board 6 and the rechargeable battery 7 are disposed inside the housing 5. The housing 5 is provided with a battery charging connection structure.

[0097] In specific implementation, the housing 5 includes a bottom shell 51 and a top shell 52, forming a first accommodating space between them. The main control board 6 and the rechargeable battery 7 are disposed in this first accommodating space.

When a movable battery 3 needs to be replaced, one is replaced at a time to ensure uninterrupted power to the smart glasses 4. After replacing both spare batteries, the two removed batteries 3 can be returned to the charging device for recharging, ready for the next replacement. After using the smart glasses 4, the two remaining movable batteries 3 are also returned to the charging device, thus achieving storage and charging of all four movable batteries 3.

[0101] In this preferred embodiment, the battery placement position 521 is a battery slot 521 adapted to the shape of the movable battery 3, and the battery charging connector is located inside the battery slot.

[0102] In practice, the battery fixing position 521 is set as a groove-shaped structure that is adapted to the shape of the battery, which can accommodate the movable battery 3 and limit the movable battery 3 in four directions, effectively preventing the movable battery 3 from losing electrical connection with the battery charging connector due to accidental displacement, which would lead to charging failure.

[0103] Similarly, the battery fixing position 521 can also be a battery clip or hook structure.

[0104] As a preferred embodiment, the battery placement position 521 is provided with a battery positioning structure.

[0105] In practice, to prevent the movable battery 3 from being placed in the wrong direction and having the opposite polarity to the battery charging connector 61, which could lead to a malfunction, the battery placement position 521 is provided with a battery positioning structure. Through the battery positioning structure, the placement direction and position of the movable battery 3 can be effectively limited, thereby ensuring that the polarity of the movable battery 3 and the battery charging connector 61 are consistent and that it can be charged smoothly.

[0106] Battery positioning structures include, but are not limited to, compatible anti-foolproof grooves / protrusions, magnetic anti-foolproof structures, etc.

[0107] In this embodiment, the battery positioning structure is a positioning magnet, and the movable battery 3 is provided with a corresponding battery positioning magnet.

[0108] In practice, a positioning magnet is set inside the housing 5, and a corresponding battery positioning magnet is set in the movable battery 3. The magnetic poles of the positioning magnet and the battery positioning magnet are opposite. When the movable battery 3 is placed in the battery placement position 521, the movable battery 3 can be placed in the correct direction under the magnetic force of the battery positioning magnet and the positioning magnet.

[0109] Similarly, a positioning magnet can be set inside the housing 5, and a corresponding ferromagnetic material can be set in the movable battery 3 to achieve the same magnetic positioning effect.

[0110] To reduce space waste, when the removable battery 3 has a built-in connecting magnet, this connecting magnet can be used as a positioning magnet. For example, the removable battery 3 has a ring-shaped connecting magnet with conductive contacts located in the middle of the ring-shaped connecting magnet. Correspondingly, a ring-shaped housing positioning magnet is provided in the battery placement position 521 of the housing 5 of the charging device, wherein the magnetic poles of the connecting magnet and the housing positioning magnet are opposite on opposite sides. The battery charging connector 61 is placed in the middle of the ring-shaped housing positioning magnet, corresponding to the conductive contacts 31 of the removable battery 3. When the removable battery 3 is placed in the battery placement position 521, the removable battery 3 can be magnetically attached to the battery placement position 521 and electrically connected to the battery charging connector 61 of the charging device, which is very convenient.

[0111] As a preferred embodiment, the housing 5 further includes a cover 53, which forms an accommodating space for accommodating the movable battery 3 when it is closed on the housing 5.

[0112] In specific implementation, in order to ensure that the housing 5 fixes the movable battery 3, the housing 5 also includes a base cover 53. When the base cover 53 can cover the side of the housing 5 where the battery placement position 521 is provided, that is, when the base cover 53 covers the front shell 52, a second housing accommodating space is formed between the base cover 53 and the front shell 52. The movable battery 3 placed in the battery placement position 521 is wrapped in the second housing accommodating space formed between the front shell 52 and the base cover 53 of the housing 5, thereby realizing the limitation and protection of the movable battery 3.

[0113] As a preferred embodiment, the housing 5 is provided with a wireless charging receiving coil, which is disposed inside the housing 5 and electrically connected to the main control board 6.

[0114] In practice, to enrich the charging methods of the charging device, a wireless charging receiving coil is provided inside the housing 5. The wireless charging receiving coil is electrically connected to the main control board 6. The wireless charging receiving coil is located on the side of the housing 5 away from the battery placement position 521. When the rechargeable battery 7 of the charging device needs to be charged, the housing 5 is placed on the wireless charging board, and the main control board 6 can convert the electromagnetic energy sensed by the wireless charging receiving coil into electrical energy and charge the rechargeable battery 7 inside the housing 5, which is very convenient.

[0115] In a preferred embodiment, the housing 5 is provided with a charging interface for charging the rechargeable battery, and the charging interface is electrically connected to the main control board 6.

[0116] In practical implementation, to facilitate power supply to the charging device, the housing 5 is equipped with a charging interface for charging the rechargeable battery 7. The charging interface is electrically connected to the main control board 6, and can be connected to a charging head to power the charging device. The charging interface includes, but is not limited to, a Type-C port, a micro USB port, a USB port, or a DC port.

[0117] It should be noted that the smart glasses in the above embodiments include, but are not limited to, AR glasses.

[0118] It will be readily understood by those skilled in the art that the above embodiments can be freely combined and superimposed without conflict.

[0119] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
