Description

Technical Field

[0001] This application relates to the field of charging technology, specifically to a charging adapter and charging device. Background Technology

[0002] Smart wearable devices can achieve functions such as health monitoring, motion tracking, information reminders, voice assistants, navigation, and playback control. With the development of technologies such as AR (Augmented Reality), VR (Virtual Reality), and MR (Mixed Reality), wearable devices such as headbands can bring users a deeper digital experience, and at the same time, accessories such as rings and bracelets that enhance the interactive experience have emerged.

[0003] Providing charging solutions for devices such as rings is a basic product function. However, existing charging cables for smartphones and other smart terminals have difficulty achieving compatibility and adaptation of charging interfaces for ring products. Therefore, providing better compatibility and convenience during the charging process has become an urgent need. Summary of the Invention

[0004] In view of this, this application provides a charging adapter and a charging device to solve at least one of the problems of poor compatibility and portability of existing charging components.

[0005] To address the aforementioned technical problems, in a first aspect, this application provides a charging adapter for charging wearable devices, comprising:

[0006] A housing, the housing including a receiving cavity;

[0007] A first terminal is disposed in the accommodating cavity and is at least partially exposed relative to the housing. The first terminal is used for electrical connection to an external power supply.

[0008] A second terminal is disposed in the accommodating cavity and is at least partially exposed relative to the housing. The second terminal is electrically connected to the first terminal. The second terminal is used for electrically connecting the wearable device. The shape of the first terminal is different from the shape of the second terminal.

[0009] The first terminal is disposed in a first direction toward the housing;

[0010] The second terminal is disposed in a second direction of the housing; the first direction and the second direction form an angle with each other, the second terminal is configured to physically connect to the wearable device and charge the wearable device by connecting to an external power source through the first terminal, and allow the second direction of the housing and the support plane to be perpendicular to each other, the support plane being used to support the wearable device.

[0011] Secondly, this application also provides a charging device, including a data cable and a charging adapter as described above, wherein the output end of the data cable is electrically connected to the first terminal.

[0012] The beneficial effects of this application are as follows: The first terminal and the second terminal of this application have different shapes, which can be adapted to different types of data cable adapters for charging. The first terminal and the second terminal are respectively set at an angle in different directions of the housing, which effectively improves the charging compatibility, improves the connection stability during the charging process, and allows the wearable device to be supported vertically relative to the supporting plane. Compared with the existing charging mode that only allows the wearable device to be placed at a fixed angle, this application effectively improves the reliable charging of the wearable device at a more flexible placement angle.

[0027] See also Figure 1-9This application provides a charging adapter 100 for charging a wearable device 200. The wearable device 200 can be a ring, bracelet, etc., and in other embodiments, the wearable device can also be smart glasses, headphones, or similar products. In some embodiments, such as Figure 3 and 9 Taking wearable device 200 as an example of a ring, device 200 can communicate with smart glasses 230 and terminal 240 (terminal 240 can be a mobile phone, tablet, computer, etc.). Wearable device 200 can function as an independent vital sign detection device, or as an interaction device for smart glasses 230 and / or terminal 240, such as performing playback, page swiping, and other related operations. In some embodiments, wearable device 200 may include a housing 201, operation buttons 204, and charging interface 203, etc. The housing 201 has a receiving hole 202 to accommodate the user's finger. Wearable device 200 may also include components such as a communication module, processor, and battery to achieve basic functions (not shown in the figure). For the internal structure of ring 200, please refer to the description in patent 2025206890015.

[0028] In another embodiment, the charging interface 203 can also be applied to other wearable devices 200 such as headphones, wristbands, and glasses.

[0029] See Figure 1-2 6-7. The charging adapter 100 provided in this application includes a housing 10, a first terminal 20, and a second terminal 30. The housing 10 includes a receiving cavity 101, which may be formed by assembling two or more sub-housings. The first terminal 20 is disposed in the receiving cavity 101 and is at least partially exposed relative to the housing 10. The first terminal 20 is used for electrical connection to an external power source; wherein the first terminal 20 can be directly electrically connected to an external power source and indirectly electrically connected to an external power source (not shown) via other intermediate data lines or extension cables 301 or plugs (not shown). Cables or accessories with power output can be understood as the external power source portion of this application.

[0030] The second terminal 30 is disposed in the accommodating cavity 101 and is at least partially exposed relative to the housing 10. The second terminal 30 is electrically connected to the first terminal 20. It can be understood that both the first terminal 20 and the second terminal 30 have portions located within the accommodating cavity 101 and portions exposed relative to the housing 10. The second terminal 30 is used for electrical connection to the wearable device 200, for example, through magnetic connection, snap-fit, or plug-in connection. The second terminal 30 can be electrically connected to the charging interface 203, and the two can be corresponding male and female connectors. The shape of the exposed portion of the first terminal 20 differs from the shape of the exposed portion of the second terminal 30. The first terminal 20 can adopt various types of the USB (Universal Serial Bus) standard, such as Lightning (Apple interface), Micro-USB, USB-C (TYPE-C), etc.; the second terminal 30 can adopt a pogo pin connector, magnetic contact connector, spring contact connector, solid pin contact connector, etc.

[0031] Combination Figure 1-2 4-5, the exposed portion of the first terminal 20 is positioned towards the first direction X of the housing 10; the exposed portion of the second terminal 30 is positioned towards the second direction Y of the housing 10; the first direction X and the second direction Y form an angle with each other, for example, the two directions are perpendicular to each other, or the angle is 30°, 45°, 60°, etc. That is, the first direction X and the second direction Y are not parallel. The second terminal 30 is configured to physically connect to the wearable device 200 and connect to an external power source through the first terminal 20 to charge the wearable device 200, and allows the second direction Y of the housing 10 to be perpendicular to the support plane S. The support plane S is used to support the wearable device 200. Taking the ring 200 as an example, the outer ring surface of the ring 200 and the support plane S can be tangent. This application allows the ring 200 to be charged upright relative to the support plane S. Compared with traditional charging docks that only allow the device 200 to be charged at a fixed horizontal placement angle, this effectively improves the charging flexibility of the ring 200. The second terminal 30 can also be located within the inner ring of the wearable device 200, in which case the charging adapter component 100 can also jointly support the ring 200. The first and second terminals of this application have different shapes, thus adapting to different types of data cable charging. The first and second terminals are respectively angled and positioned in different directions of the housing, effectively improving charging compatibility, enhancing connection stability during charging, and allowing the wearable device to be vertically supported relative to the supporting plane. Compared to existing charging modes that only allow wearable devices to be placed at a fixed angle, this application effectively improves the reliability of charging the wearable device at a more flexible placement angle.

[0032] In some embodiments, such as Figure 1 , 45. The first direction X and the second direction Y are perpendicular to each other. The first terminal 20 and the second terminal 30 are spaced apart. The second terminal 30 is also configured to physically connect to the wearable device 200 and allow the second direction Y of the housing 10 and the supporting plane S to be parallel to each other. It can be understood that the second terminal 30 can be placed in the inner ring of the ring 200. Since the orientation of the first terminal 20 of the charging adapter component 100 as a power input interface and the orientation of the second terminal 30 as a power output interface (relative to the ring 200 as an input interface) are perpendicular to each other, the ring can be charged at different placement angles, i.e., charging upright and charging flat, effectively improving the flexibility of charging scenarios. The housing 10 can be made of rigid material, unlike the flexible or braided materials of some existing charging cables. The charging adapter component 10 is beneficial for providing partial stable support for the ring 200 during charging, making it less prone to tangling and knotting, thus facilitating carrying, and less likely to damage the internal electronic components. In the second direction Y, the projected area of ​​the first terminal 20 relative to the housing 10 is greater than the projected area of ​​the second terminal 30 relative to the housing 10, that is, the second terminal 30 is smaller than the first terminal 20, which is beneficial for the second terminal 30 to be placed on the ring.

[0033] In some embodiments, such as Figure 1 , 2 In the second direction Y, the thickness H2 of the housing 10 to which the second terminal 30 is located is less than the thickness H1 of the housing 10 to which the first terminal 20 is located. It can be understood that the thickness H2 being less than the thickness H1 allows the portion of the housing 10 exposed relative to the inner ring of the ring 200 to be supported on the support plane S during charging if the ring 200 is upright. The maximum width D2 of the projection profile of the second terminal 30 relative to the housing 10 in the second direction Y is less than the maximum width D1 of the projection profile of the first terminal 20 relative to the housing 10 in the first direction X. The projection outline of the second terminal 30 relative to the housing 10 in the second direction Y can be circular, and the maximum width D2 can be the diameter of the circle. The projection outline of the first terminal 20 relative to the housing 10 in the first direction X can be capsule-shaped or elliptical, and the maximum width D1 can be the maximum length of the shape, such as the long side of an ellipse. It is understood that since the ring 200 needs to meet the finger sizes of different users, the ring 200 has different inner diameters. Sizes that are too wide, such as Type-C, are not easy to be placed in the inner ring of the ring 200 with a smaller inner diameter for charging. In this application, the maximum width of the projection outline of the second terminal 30 is designed to be smaller than that of the first terminal 20. The second terminal 30 is smaller than the first terminal 20 in both projection area and outer outline size, which is conducive to the second terminal 30 being placed in the inner ring of the ring 200 for charging, thus meeting the charging needs of rings 200 with different inner diameters.

[0034] In some embodiments, combined with Figure 1-24-7, the charging adapter assembly 100 also includes an electrical conductor 40, which can be a printed circuit line, a metal conductor, or a flexible conductor, etc.; the first terminal 20 includes a Type-C interface 22 and a first circuit board 24 electrically connected to each other. The Type-C interface 22 can be a male or female connector, and the first circuit board 24 can be rectangular, quadrilateral, or elliptical, etc. The Type-C interface 22 and the first circuit board 24 can be electrically soldered to each other; the second terminal 30 includes contact terminals 32 and a second circuit board 34 electrically connected to each other. The second circuit board 34 can be circular, square, etc. The electrical conductor 40 electrically connects the first circuit board 24 and the second circuit board 34; the Type-C interface 22 is used for electrically connecting to an external power source, specifically through a data cable and plug, such as household AC power or a power bank. Contact terminals 32 and 33 are used for electrically connecting to the wearable device 200, meaning that contact terminals 32 and 33 can be electrically connected to the charging interface 203. The contact terminals can be pogo pins, metal contacts, etc. Figure 8 As shown, the first circuit board 24 can be a rectangular rigid printed circuit board. The 24 pins in the upper and lower rows inside the Type-C interface 22 are electrically soldered to the first circuit board 24. The first circuit board 24 may also have a first resistor R1 and a second resistor R2, which are electrically connected to the CC1 and CC2 pins inside the Type-C interface 22, respectively. The second circuit board 34 can be a circular rigid printed circuit board. The end face of the second circuit board 34 has a central soldering area 341 and a peripheral soldering area 342 surrounding the central soldering area 341. Contact terminals 32 and 33 include a central contact terminal 32 and peripheral contact terminals 33. The peripheral contact terminals 33 surround the central contact terminal 32 and are spaced apart from it. The central contact terminal 32 and the central soldering area 341 are electrically connected. The peripheral contact terminal 33 and the peripheral soldering area 342 are electrically connected. The electrical wire 40 may include two wires. One end of the electrical wire 40 is electrically connected to the first circuit board 24 and indirectly to the VBUS pin of the Type-C interface 22, and the other end is electrically connected to the center soldering area 341 of the second circuit board 34 and electrically connected to the center contact terminal 32. The other electrical wire 40 is electrically connected to the first circuit board 24 and indirectly to the GND pin of the Type-C interface 22, and the other end is electrically connected to the peripheral soldering area 342 of the second circuit board 34 and electrically connected to the peripheral contact terminal 33. The above method converts the power entering from the Type-C interface 22 into the input power of the smaller center contact terminal 32 and peripheral contact terminal 33, thereby charging the ring 200.

[0035] In some embodiments, combined with, for example Figure 1-24-7, the housing 10 includes a first housing 12 and a second housing 14, which form a receiving cavity 101. The first housing 12 has a first notch 120, and the second housing 14 has a first through hole 141 and a second notch 140. The Type-C interface 22 and the first circuit board 24 are arranged parallel to the bottom wall 124 of the first housing 12. The Type-C interface 22 is at least partially exposed relative to the first notch 120 and the second notch 140. The outer contour formed by the first notch 120 and the second notch 140 is exactly matched with the outer contour size of the Type-C interface 22. It can be understood that most of the Type-C interface 22 is housed in the receiving cavity 101, with only the end in the first channel 120 and the second notch 140. The opening 140 is exposed; the second circuit board 34 is arranged parallel to the bottom wall 124, and the contact terminals 32 and 33 extend in a direction away from the bottom wall 124 and are arranged perpendicular to the second circuit board 34, that is, the center contact terminal 32 and the peripheral contact terminal 33 are arranged perpendicular to the second circuit board 34. The contact terminal 32 is located in the first through hole 141 and is exposed relative to the first through hole 141. Most of the center contact terminal 32 and the peripheral contact terminal 33 are located inside the receiving cavity 101, and only the ends are exposed relative to the first through hole 141. The height of the center contact terminal 32 can be higher than the height of the peripheral contact terminal 33. The center contact terminal 32 can be an elastic metal contact, that is, the center contact terminal 32 can elastically expand and contract relative to the peripheral contact terminal 33. In some embodiments, if the contact terminal 32 is a plurality of metal contacts arranged at intervals, the first through hole 141 can be a plurality of spaced-apart metal contacts, with each through hole corresponding to a metal contact.

[0036] In the second direction Y, the projected area of ​​the Type-C interface 22 relative to the first housing 12 is larger than the projected area of ​​the second circuit board 34 relative to the first housing 12. It can be understood that the second circuit board 34 has a smaller projected area relative to the Type-C interface 22, allowing the contact terminal 32 to maintain the same or smaller projected area as the second circuit board 34. Consequently, the entire second terminal 30 has a smaller projected area relative to the entire first terminal 20. Therefore, the second terminal 30 can be inserted into more rings 200 with different inner diameters for charging, improving the compatibility and convenience of the charging adapter assembly 100.

[0037] In some embodiments, such as Figure 4-7The second housing 14 is also provided with a plurality of first protrusions 142 and second protrusions 143. For example, the first protrusions 142 may include two or three; the second protrusions 143 may include four, five or six, etc. The plurality of second protrusions 143 are arranged at intervals along the circumference of the second housing 14. The first circuit board 24 is provided with spaced positioning holes 242. The positioning holes 242 can be through holes, and the number of positioning holes 242 can be the same as the number of first protrusions 142. The first housing 12 is provided with a plurality of first connecting holes 121 and second connecting holes 122. Both the first connecting holes 121 and the second connecting holes 122 can be blind holes. The number of the first connecting holes 121 and the second connecting holes 122 can be the same as the number of the first protrusions 142 and the second protrusions 143. The plurality of second connecting holes 122 are spaced apart along the circumference of the first housing 12. The first protrusions 142 pass through the positioning holes 242 and connect to the first connecting holes 121. The second protrusions 143 connect to the second connecting holes 122 to connect the first housing 12 and the second housing 14. The first connecting holes 121, the second connecting holes 122, the first protrusions 142 and the second protrusions 143 can be integrally formed with the corresponding housings. The first protrusions 142 and the second protrusions 143 have columnar structures. The above method can realize the fixed assembly of the first circuit board 24, and at the same time realize the fixed assembly of the first housing 12 and the second housing 14, effectively improving the overall assembly efficiency.

[0038] Continuing with examples 1-7, the second housing 14 is provided with a protrusion 145. In the second direction Y, the end face of the protrusion 145 is higher than the end face of the first through hole 141. The protrusion 145 is used to contact the supporting plane S. It can be understood that in the above embodiments, the thickness H1 can be formed by the protrusion 145. The end face of the protrusion 145 facing away from the first housing 12 can be a plane, such as... Figure 5 As shown, after the housing 10 and accessory 300 are plugged in, the protrusion 145 can contact the supporting plane S, thereby preventing the ring 200 from rotating when it is standing upright for charging. This is beneficial for the charging adapter to provide stable support for the wearable device 200 (ring 200) when it is placed for charging.

[0039] See Figure 6-7 The first housing 12 has a shallow groove 123 surrounding the second connecting hole 122 in the circumferential direction, and the second housing 14 has a flange 144 surrounding the second protrusion 143 in the circumferential direction. The shallow groove 123 and the flange 144 are sealed together. For example, glue can be placed in the shallow groove 123 and then the flange 144 can be placed into the shallow groove 123 and the two can be sealed together with glue, which effectively reduces the risk of the housing 10 becoming loose and makes the charging adapter assembly more robust overall.

[0040] In some embodiments, such as Figure 6-7The contact terminals 32 and 33 may also include a center contact terminal 32, a peripheral contact terminal 33, and a magnet 35. The peripheral contact terminal 33 surrounds the center contact terminal 32 and is spaced apart from the center contact terminal 32. A magnet 35 is provided between the center contact terminal 32 and the peripheral contact terminal 33. The second circuit board 34 is provided with a center soldering area 341 and a peripheral soldering area 342. The center contact terminal 32 and the center soldering area 341 are electrically connected, and the peripheral contact terminal 33 and the peripheral soldering area 342 are electrically connected. It can be understood that the charging interface 203 is also provided with a center metal contact and a peripheral metal contact (not shown in the figure) corresponding to the contact terminal type. The magnet 35 can magnetically attract the charging interface 203 on the ring, making the physical connection between the center contact terminal 32, the peripheral contact terminal 33, and the charging interface 203 more secure and ensuring the stability of the charging process.

[0041] Continue reading Figure 6 A slot 222 is provided on the side of the Type-C interface 22 away from the plug-in port 221. The first circuit board 24 is snapped into the slot 222. The slot 222 can be located in the middle of the Type-C interface 22. The slot 222 can effectively prevent the first circuit board 24 from becoming loose in the second direction Y. The upper and lower rows of electrical pins of the Type-C interface 22 will be electrically connected to the first circuit board 24 located in the middle with a shorter distance. In some embodiments, the upper and lower rows of electrical pins of the Type-C interface 22 can be electrically soldered to two different surfaces of the first circuit board 24 respectively. The above design can effectively save the installation space of the first circuit board 24 and the Type-C interface 22, and make the electrical connection between the upper and lower rows of electrical pins of the Type-C interface 22 and the first circuit board 24 more secure.

[0042] In some embodiments, such as Figure 4 , 6 -7. The charging adapter 100 also includes a snap-fit ​​part 50. One end of the snap-fit ​​part 50 is connected to the housing 10, and the other end is away from the housing 10 and has a latch 52. The latch 52 is configured with a variable opening shape and is used to snap onto an external accessory 300. The snap-fit ​​part 50 can be made of flexible, elastic, or textile materials, etc. The external accessory 300 can be a data cable, extension cable, or charging plug, etc. Taking the external accessory 300 as a data cable as an example, the Type-C interface 22 can be a male connector, and the data cable has a Type-C female connector. The external accessory 300 can be snapped into the latch 52 first, and then the Type-C male and female connectors can be plugged in, effectively preventing the risk of the charging adapter 100 falling off during charging.

[0043] In some embodiments, such as Figure 4 , 6-7. The snap-fit ​​part 50 includes a flexible connecting section 51, a slider 53, and a knot 55. The flexible connecting section 51 and the knot 55 can be made entirely of textile material, while the slider 53 can be made of plastic, rubber, or other materials. The knot 55 is formed by knotting the flexible connecting section 51 and is located at both ends of the flexible connecting section 51. The housing 10 also has a second through hole 146, for example, two second through holes 146. The knot 55 is connected to the end of the flexible connecting section 51. The knot 55 is located inside the receiving cavity 101 and its outer contour dimension is larger than the second through hole 146, which can prevent the flexible connecting section 51 from detaching from the second housing 14. The flexible connecting section 51 passes through the second through hole 146 and the slider 53, and divides the snap-fit ​​52 into a first snap-fit ​​521 and... The second latch 522 and slider 53 are configured to allow sliding on the flexible connecting section 51 and to allow adjustment of the opening size of the first latch 521 and the second latch 522. The first latch 521 and / or the second latch 522 are used to latch the external accessory 300. Therefore, the user can adjust the latching position of the latching part 50 according to the structure of the external accessory 300, and can choose to connect using the first latch 521 or the second latch 522 according to their preference. This latching can be understood as a binding, binding, or hanging connection method, such as... Figure 5 As shown, the second latch 522 can pass over the plug of the accessory 300 and be secured to the cable end of the accessory 300. The user can adjust the slider 53 to adjust the opening size and securing position of the second latch 522. This can improve the connection stability of the adapter component 100 during charging. In other embodiments, the first latch 521, the second latch 522, and the latch 52 can also be attached to items such as keychains, backpacks, accessories, or shelves, which is convenient for storage and reduces the probability of the charging adapter component 100 being lost.

[0044] One assembly method of the charging adapter assembly 100 of this application is to pass the flexible connecting section 51 through the second through hole 146 and then tie it at the end to form a joint 55; electrically connect the first terminal 20 and the second terminal 30; then snap the first protrusion 142 of the second housing 14 into the positioning hole 242 of the first circuit board 24; apply glue into the shallow groove 123 of the first housing 12; and then snap the first protrusion 142 and the second protrusion 143 of the second housing 14 into the first connecting hole 121 and the second connecting hole 122 of the first housing 12, respectively, and press the first housing 12 and the second housing 14 together. The above assembly method is efficient and low in cost.

[0045] This application also provides a charging device, including a data cable and the aforementioned charging adapter 100. The output end of the data cable is electrically connected to the first terminal 20.
