Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0039] The specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this application will not be described separately.

[0040] In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate that the objects have the sameness or relationship. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the orientation under normal use conditions, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use conditions.

[0041] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0042] Please refer to Figure 6 This application provides a support 10, which includes a neck strap assembly 11 and a cable 12. The neck strap assembly 11 includes a neck strap body 111, a first receiving structure 112, and a second receiving structure 113. The neck strap body 111 is flexible and is used to hang on a person's neck.

[0043] The neck halter body 111 is flexible, which means that the neck halter body 111 can undergo elastic or plastic deformation without breaking when subjected to bending stress. In other words, the neck halter body 111 has a high elongation at break and a low modulus, which allows the neck halter body 111 to remain intact within a large deformation range. This allows the neck halter body 111 to adjust its width to fit different people's necks.

[0044] In some embodiments, the first receiving structure 112 is connected to one end of the neck hanger body 111 and is used to receive the first power supply 20;

[0045] The second accommodating structure 113 is connected to the neck hanger body 111 and is far away from the first accommodating structure 112. The second accommodating structure 113 is used to accommodate the second power supply 30.

[0046] One end of the wire 12 is electrically connected to the first power source 20, and the other end of the wire 12 is electrically connected to the second power source 30, so that the first power source 20 charges the second power source 30 through the wire 12.

[0047] In this embodiment, the first power source 20 charges the second power source 30 via the cable 12, thereby increasing the battery life of the second power source 30.

[0048] It is understood that the first power source 20 in this application embodiment refers to a power supply device capable of charging the second power source 30, such as a power bank. The second power source 30 in this application embodiment refers to a power supply device capable of supplying power to electronic devices, such as a power module for a head-worn device. The head-worn device can be VR / AR glasses, Bluetooth headsets, or other portable electronic devices. This application embodiment will use the example of the second power source 30 being a power module for a head-worn device for explanation.

[0049] The bracket 10 provided in this embodiment can be hung on the neck of a person via the neckband body 111. It also houses the first power supply 20 and the second power supply 30, and the first power supply 20 can charge the second power supply 30, thereby increasing the battery life of the second power supply 30, which in turn increases the battery life of the head-wearing device. Moreover, having the second power supply 30 hung on the neck of a person via the bracket 10 also helps reduce the weight of the head-wearing device, thus increasing the wearing comfort of the head-wearing device.

[0050] It is understood that the second accommodating structure 113 is connected to the neck hanger body 111 and is far away from the first accommodating structure 112, meaning that the second accommodating structure 113 can be located at the other end of the neck hanger body 111 or at other locations on the neck hanger body 111.

[0051] In some embodiments, such as Figure 1 , Figure 2 and Figure 8 As shown, the neck strap body 111 includes a curved portion 1111 and a connecting portion 1112 connected to each other. The curved portion 1111 is used to rest against the back of a person, and the connection between the curved portion 1111 and the connecting portion 1112 is used to rest against the shoulders of a person. The connecting portion 1112 is used to extend from the end of the curved portion 1111 to the front of the person. A first receiving structure 112 is connected to the end of the connecting portion 1112 away from the curved portion 1111, and a second receiving structure 113 is connected to the curved portion 1111.

[0052] By using the connection between the curved part 1111 and the connecting part 1112 to rest against the human shoulder, the shoulder bears the weight of the support 10, which helps to reduce the pressure of the support 10 and the first power supply 20 and the second power supply 30 placed on the support 10 on the human neck.

[0053] The curved portion 1111 rests against the back of the human body, which helps the second receiving structure 113 to rest against the back of the human body. When the second receiving structure 113 is placed on the second power source 30, it allows the second power source 30 to rest against the back of the human body, thus helping to make the second power source 30 fit snugly against the back of the human body and improving the overall aesthetics of the support 10 placed on the human body. The connecting portion 1112 extends from the end of the curved portion 1111 to the front of the human body, that is, the first receiving structure 112 is located at the front of the human body.

[0054] In some embodiments, please refer to Figure 1There are two connecting parts 1112, which are respectively connected to the two ends of the curved part 1111. This arrangement facilitates the installation of two first receiving structures 112, and also allows the two connection points of the curved part 1111 and the connecting parts 1112 to rest on both sides of the human shoulder, making it easier for the bracket 10 to be placed on the human shoulder and neck as a whole.

[0055] In some embodiments, the cable includes a cable body, a first interface 121, and a second interface 122. One end of the first interface 121 is electrically connected to the cable body, and the other end of the first interface 121 is electrically connected to a first power supply 20. One end of the second interface 122 is electrically connected to the cable body, and the other end of the second interface 122 is electrically connected to a second power supply 30. The cable body is disposed inside the neckband body 111. The placement of the cable body inside the neckband body 111 helps improve the aesthetic appearance of the neckband body 111.

[0056] In some embodiments, the second interface 122 includes an interconnected cable portion and a connector, both of which are exposed outside the bend 1111. The connector is used for plugging and unplugging into the charging interface of the second power supply 30. Thus, the second power supply 30 is charged using the cable portion and the connector.

[0057] In some embodiments, please refer to Figure 6 The outer surface of the curved portion 1111 has a storage groove 1111a, which is used to accommodate the cable section and the connector. In this way, the cable section and the connector are stored, making the structure of the bracket 10 neat and minimizing the interference of the cable section and the connector with the neck or back of the user.

[0058] For example, please continue reading Figure 6 The storage slot 1111a is located on the side of the curved portion 1111 away from the second receiving structure 113. That is, the storage slot 1111a is located on the side of the curved portion 1111 closer to the neck of the human body. When the second interface 122 does not need to charge the second power supply 30, the second interface 122 can be located in the storage slot 1111a. The storage slot 1111a is located on the side of the curved portion 1111 closer to the neck of the human body, which makes it easy to hide the second interface 122 and helps to improve the appearance of the bracket 10.

[0059] In some embodiments, such as Figure 7 As shown, the sidewall of the storage slot 1111a has a protrusion 1111b, which is press-fitted with the cable section to achieve a snap-fit ​​connection. When the second interface 122 needs to be used, the cable section can be pulled out by force. When the second interface 122 needs to be stored, the cable section can be snapped into the storage slot 1111a and press-fitted with the protrusion 1111b.

[0060] For example, protrusions 1111b are formed on both sides of the sidewall of the storage groove 1111a.

[0061] In some embodiments, such as Figure 6 As shown, the first interface 121 includes a first conductive terminal disposed on the bottom wall of the first accommodating structure 112. The first conductive terminal is used for conductive contact with the terminal of the first power supply 20. This enables conductive contact between the first power supply 20 and the wire 12, so that the first power supply 20 can supply power to the wire 12 through the first conductive terminal, thereby supplying power to the second power supply 30.

[0062] For example, such as Figure 6 As shown, the bracket 10 includes a first magnetic structure 13, which is disposed in the first receiving structure 112. The first magnetic structure 13 is used to magnetically engage with the first power supply 20. The magnetic attraction of the first power supply 20 by the first magnetic structure 13 secures the first power supply 20 and facilitates its removal from the first receiving structure 112. In other words, this achieves a detachable connection between the first power supply 20 and the first receiving structure 112, allowing the user to easily remove the first power supply 20 for charging.

[0063] It is understood that the first magnetic structure 13 may include a magnet or other components with magnetic attraction.

[0064] In some embodiments, the first magnetic attraction structure 13 is disposed on the bottom wall of the first receiving structure 112. This arrangement helps to align the first power supply 20 by utilizing the magnetic attraction force generated by the first magnetic attraction structure 13 on the bottom wall of the first receiving structure 112 when the first power supply 20 is installed. Furthermore, the first magnetic attraction structure 13 being disposed on the bottom wall of the first receiving structure 112 allows for a larger area of ​​the surface of the first power supply 20 that is in contact with the first magnetic attraction structure 13, thereby increasing the stability of the first power supply 20 when installed in the first receiving structure 112.

[0065] In some embodiments, the first magnetic attraction structure 13 is ring-shaped. The magnetic field generated by the ring-shaped first magnetic attraction structure 13 is more uniform in the central region. This helps the first power supply 20 to be subjected to magnetic force more evenly when placed, reducing localized areas of excessively strong or weak magnetic force. The ring shape also allows the first magnetic attraction structure 13 to provide magnetic force in multiple directions, thereby helping to enhance the stability of the first power supply 20 installed in the first receiving structure 112. Moreover, the ring-shaped first magnetic attraction structure 13 also facilitates the provision of space inside and outside the ring for the installation of other components, such as the first conductive terminal.

[0066] In the embodiment where the first conductive terminal is located on the bottom wall of the first accommodating structure 112, since the annular first magnetic attraction structure 13 is also located on the bottom wall of the first accommodating structure 112, it helps to further increase the stability of the conductive contact between the first conductive terminal and the conductive terminal of the first power supply 20, thereby helping to improve the stability of the first power supply 20 supplying power to the second power supply 30.

[0067] In some embodiments, such as Figure 4 As shown, the second accommodating structure 113 includes a base 1132 and a protective shell 1133. The protective shell 1133 is connected to the base 1132 and has the second accommodating structure 113. The protective shell 1133 is used to provide protection for the second power supply 30.

[0068] In some embodiments, the inner wall of the protective shell 1133 is interference-fitted with the second power supply 30, which helps to improve the stability of the second power supply 30 within the protective shell 1133, that is, helps to increase the stability of the power module of the head-worn device within the protective shell 1133.

[0069] In some embodiments, the bracket 10 includes a second magnetic structure 14 disposed within the protective shell 1133. The second magnetic structure 14 is used to magnetically engage with the second power supply 30. The second magnetic structure 14 enables a detachable connection between the second power supply 30 and the protective shell 1133; that is, the second magnetic structure 14 can both fix the second power supply 30 and allow it to be separated from the protective shell 1133.

[0070] In some embodiments, the second magnetic structure 14 includes a plurality of magnets spaced apart along the extension direction of the bottom wall of the protective shell 1133, which is at the height of the human body. The multiple spaced magnets can provide magnetic force at multiple points to the second power supply 30, which helps to ensure the stability of the second power supply 30 installed in the second housing structure 113.

[0071] For example, the bracket 10 includes a third magnetic structure, which is disposed on the base 1132, and the protective shell 1133 is fixed to the base 1132 by the third magnetic structure. That is, the protective shell 1133 and the second power supply 30 are detachably connected to the base 1132. The user can choose to remove only the second power supply 30, or remove the protective shell 1133 and the second power supply 30 as a whole.

[0072] In some embodiments, the third magnetic structure includes multiple magnets spaced apart along the extension direction of the bottom wall of the base 1132, which extends in the direction of the height of the human body. The multiple spaced magnets can provide magnetic force at multiple points for the protective shell 1133, which helps to increase the stability of the protective shell 1133 when mounted on the base 1132.

[0073] In some embodiments, the base 1132, the bent portion 1111, the connecting portion 1112, and the first accommodating structure 112 are integrally formed. This facilitates manufacturing, helps reduce installation steps, thereby reducing splicing and installation marks on the bracket 10, making the overall appearance of the bracket 10 more harmonious and neat, and helping to improve the aesthetics of the bracket 10.

[0074] In some embodiments, the base 1132, the curved portion 1111, the connecting portion 1112, and the first accommodating structure 112 are integral silicone parts. The silicone parts are elastic and soft, allowing the neckband body 111 to conform to the curves of the neck and shoulders of the human body, providing a comfortable wearing experience. Moreover, the silicone material has a smooth surface and a soft touch, does not irritate the skin, and is suitable for long-term wear.

[0075] Based on the bracket 10 provided in the embodiments of this application, please refer to Figure 1 , Figure 2 , Figure 3 This application also provides a power supply device, including a first power supply 20 and a bracket 10 provided in any embodiment of this application. The first power supply 20 is detachably disposed in the first accommodating structure 112.

[0076] In other words, the first power supply 20 can be removed from the first accommodating structure 112 to facilitate charging of the first power supply 20. After the first power supply 20 is fully charged, it can be reassembled into the first accommodating structure 112.

[0077] In an embodiment where the bracket 10 has two first receiving structures 112, that is, the two first receiving structures 112 can simultaneously house the first power supply 20, and the two first power supplies 20 alternately supply power to the second power supply 30. This helps to further increase the battery life of the second power supply 30, and there is no need to remove the wearable device to charge it.

[0078] It is understood that in other embodiments, the number of first power sources 20 may also be only one, which can be determined based on the power capacity of the second power source 30 itself, the power capacity of the first power source 20, and the battery life of the wearable device.

[0079] In some embodiments, the first power supply 20 includes a housing 21, an energy storage element 22, and a second conductive terminal 23. The energy storage element 22 is disposed inside the housing 21, one end of the second conductive terminal 23 is electrically connected to the energy storage element 22, and the other end of the second conductive terminal 23 is exposed on the outer surface of the housing 21 (see [link]). Figure 3 The second conductive terminal 23 is used to make conductive contact with the first conductive terminal 121. Thus, by making conductive contact with the first conductive terminal, the first power supply 20 supplies power to the wire 12.

[0080] For example, the first conductive terminal and the second conductive terminal 23 can be spring pins or spring sheets, etc.

[0081] It is understandable that the energy storage element 22 can be a lithium-ion battery, a polymer lithium-ion battery, etc.

[0082] In some embodiments, the first power source 20 further includes a conversion circuit and a magnetic induction coil. The magnetic induction coil is electrically connected to the energy storage element 22 through the conversion circuit, which converts the direct current (DC) power of the energy storage element 22 into alternating current (AC). This configuration allows the first power source 20 to function as a standalone wireless charging bank for charging other electronic devices such as mobile phones, tablets, and smart bracelets after being detached from the first housing structure 112.

[0083] In some embodiments, such as Figure 5 As shown, the first power supply 20 includes a magnetic suction component 24, which is fixed to the inner wall of the housing 21 near the second conductive terminal 23. That is, the magnetic suction component 24 can be used to magnetically fix the housing 21 to the first receiving structure 112, and also facilitates the removal of the first power supply 20 from the first receiving structure 112. Furthermore, since the magnetic suction component 24 is fixed to the inner wall near the second conductive terminal 23, while the second conductive terminal 23 is in conductive contact with the first conductive terminal, the magnetic suction component 24 also fixes the first power supply 20 to the first receiving structure 112, thus helping to increase the stability of the conductive contact between the second conductive terminal 23 and the first conductive terminal.

[0084] In an embodiment where the bracket 10 has a first magnetic attraction structure 13, the magnetic attraction between the first magnetic attraction structure 13 and the magnetic attraction component 24 can be used to further improve the stability of the first power supply 20 within the first accommodating structure 112.

[0085] It is understood that in embodiments where the first magnetic attraction structure 13 is annular, the magnetic attraction component 24 is also annular, and the cross-section of the annular first magnetic attraction structure 13 along its thickness direction is the same as the cross-section of the annular magnetic attraction component 24 along its thickness direction. This facilitates the fitting and fixing of the annular first magnetic attraction structure 13 and the annular magnetic attraction component 24.

[0086] In some embodiments, such as Figure 5 As shown, the first power supply 20 includes a housing 21 and a lifting structure 25. The lifting structure 25 is fixedly mounted on the housing 21. The groove sidewall of the first receiving structure 112 has an opening 1122 for the lifting structure 25 to enter and exit. The lifting structure 25 passes through the opening 1122 and extends to the outside of the first receiving structure 112. This allows the user to easily remove the first power supply 20 from the first receiving structure 112 using the lifting structure 25.

[0087] In some embodiments, the lifting structure 25 is strip-shaped, with both ends fixed inside the housing 21 to form a closed loop on the outside of the housing 21. This allows the user's fingers to easily insert into the closed loop to apply force and detach the first power supply 20. Furthermore, a lanyard can be attached to the closed loop formed by the lifting structure 25, making the first power supply 20 easy to carry when it is removed and used as a wireless charging bank.

[0088] In some embodiments, such as Figure 5 As shown, the first power supply 20 includes a pressure block 26 and a fastener (not shown in the figure). The pressure block 26 is used to fix the two ends of the lifting structure 25 to the inner wall of the housing 21, and the fastener is used to fasten the pressure block 26 to the inner wall of the housing 21. In this way, the two ends of the lifting structure 25 are fixed to the inner wall of the housing 21.

[0089] Understandably, fasteners can be bolts, screws, pins, etc.
