Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to a wireless charging structure and electronic equipment for a watch. Background Technology

[0002] A smartwatch is a watch with information processing capabilities that meets the basic technical requirements of a watch. In addition to telling time, a smartwatch should also have one or more functions such as reminders, navigation, calibration, monitoring, and interaction; the display methods include pointers, numbers, and images.

[0003] Currently, smartwatches are charged wirelessly. A wireless charger consists of a wireless charging coil and a magnet. When a smartwatch needs charging, the magnet on the smartwatch attracts the magnet on the wireless charger, securing the smartwatch and allowing the wireless charging coil to charge it. However, this design means that each wireless charger can only charge one type of smartwatch. Different types of smartwatches require different wireless chargers, leading to incompatibility between different smartwatches and different charger types. For example, Apple Watches and Samsung Watches have different magnetic polarities. If an Apple Watch uses an S-pole magnet, the compatible charger must have the N-pole facing up; if a Samsung Watch uses an N-pole magnet, the compatible charger must have the S-pole facing up. This reduces the convenience of charging smartwatches.

[0004] In view of the above problems, some wireless charging structures for watches (such as the prior patent with authorization announcement number CN220754406U) set a wireless charging coil on the N pole and S pole of the magnet respectively. By switching the orientation of the wireless charging structure on the smartwatch, the N pole or S pole of the magnet is facing upwards, thereby adapting to the charging needs of different types of smartwatches.

[0005] With the diversification of electronic device functions, more and more electronic devices are equipped with this highly compatible wireless charging structure for watches. This type of wireless charging structure for watches is generally rotatably mounted on electronic devices via a pivot, and the magnetic pole orientation can be switched by rotating the wireless charging structure.

[0006] In actual use, because the circuit board in the wireless charging structure of the watch needs to be electrically connected to the circuit board in the electronic device, a wire hole or wire groove is opened in the hinge to avoid the gap for the wire. This reduces the structural strength of the hinge itself and increases the risk of failure. The weight of the smartwatch and the weight of the wireless charging structure are both supported by the hinge. Due to the excessive load on the hinge, the risk of hinge failure is further increased. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a wireless charging structure and electronic device for watches, so as to solve the problem that the existing flip-type compatible wireless charging structure for watches has a significantly reduced structural strength and a high risk of failure because the hinge needs to open a wire hole to connect the circuit and bear the entire weight of the smartwatch and charging components at the same time.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a wireless charging structure for a smartwatch, comprising a charging component and a rotating shaft, wherein the charging component rotates around the central axis of the rotating shaft, and the charging component has magnetic charging positions for wirelessly charging a smartwatch on opposite sides, and further comprising a support base and an auxiliary shaft, wherein the rotating shaft is rotatably mounted on the support base, the auxiliary shaft is rotatably mounted between the support base and the charging component, the charging component is rotatably connected to the auxiliary shaft, and the central axis of the auxiliary shaft coincides with the central axis of the rotating shaft.

[0009] Furthermore, the support base is provided with a support ring extending around the outer side wall of the charging assembly, and the auxiliary shaft is disposed on the support ring.

[0010] Furthermore, when the smartwatch is wirelessly charged, the support ring directly contacts and supports the smartwatch.

[0011] Furthermore, the auxiliary shaft and the support ring are integrally formed as a single structure.

[0012] Furthermore, the support base is provided with a connecting groove and a rotating hole, the connecting groove is used to connect electronic devices, the rotating shaft is rotatably mounted in the rotating hole, and the rotating shaft is provided with a wire-passing hole that connects the connecting groove and the inside of the charging component.

[0013] Furthermore, the outer side wall of the rotating shaft is provided with a first snap-fit ​​protrusion and a second snap-fit ​​protrusion on opposite sides, and the connecting groove is provided with a snap-fit ​​groove; when one of the two magnetic charging positions of the charging component is vertically upward, the first snap-fit ​​protrusion snaps into the snap-fit ​​groove; when the other magnetic charging position of the two magnetic charging positions of the charging component is vertically upward, the second snap-fit ​​protrusion snaps into the snap-fit ​​groove.

[0014] Furthermore, the connecting groove is also provided with a first limiting protrusion and a second limiting protrusion, and the outer side wall of the rotating shaft is provided with a third limiting protrusion; when the first locking protrusion is locked in the locking groove, the third limiting protrusion abuts against the first limiting protrusion; when the second locking protrusion is locked in the locking groove, the third limiting protrusion abuts against the second limiting protrusion.

[0015] Furthermore, both of the magnetic charging positions are equipped with an identification structure.

[0016] Furthermore, the identification structure is a positioning groove located at the magnetic charging position, and the positioning groove is used to connect with the charging contact part of the smartwatch.

[0017] To solve the above-mentioned technical problems, this utility model also provides an electronic device, including the above-mentioned wireless charging structure for watches.

[0018] The beneficial effects of this utility model are as follows: The wireless charging structure and electronic device for watches provided by this utility model, by setting an auxiliary shaft coaxial with the rotating shaft between the support base and the charging component, makes the charging component form a simply supported beam structure with double-point support, which constrains radial movement and axial sway to enhance rotational stability, reduce fatigue wear of the rotating shaft and extend its life, thereby avoiding the risk of fracture failure caused by weakened structural strength when the rotating shaft is provided with a clearance structure to connect the internal circuit, significantly improving reliability and service life, maintaining the compatibility advantage of flipping and switching the dual-sided magnetic charging position, reducing the structural precision requirements, and ensuring a stable and shaky charging process.

[0021] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0022] Please refer to Figure 2 as well as Figure 4 A wireless charging structure for a smartwatch includes a charging component 2 and a rotating shaft 3. The charging component 2 rotates around the central axis of the rotating shaft 3. The charging component 2 has magnetic charging positions 21 for wirelessly charging the smartwatch on opposite sides. It also includes a support base 1 and an auxiliary shaft 4. The rotating shaft 3 is rotatably mounted on the support base 1. The auxiliary shaft 4 is rotatably mounted between the support base 1 and the charging component 2. The central axis of the auxiliary shaft 4 coincides with the central axis of the rotating shaft 3.

[0023] The working principle of the wireless charging structure for the watch is as follows: the load-bearing and rotation are decoupled through functional separation: the charging component 2 rotates stably in the support base 1 with the rotating shaft 3 and the auxiliary shaft 4 as the rotation center, so that one of the magnetic charging positions 21 on both sides faces upward to adapt to smart watches with different polarities; when the smart watch is placed in the charging position, its bottom gravity is directly transmitted to the rotating shaft 3 and the auxiliary shaft 4. The rotating shaft 3 only transmits the torque required to drive the charging component 2 to rotate without bearing the bending moment and shear force generated by the weight of the watch itself. Thus, when the rotating shaft 3 is provided with an open structure for circuit connection, the risk of strength failure due to structural weakening is avoided.

[0024] As can be seen from the above description, the beneficial effects of this utility model are as follows: by sharing the weight of the smartwatch with the auxiliary shaft 4, the load on the rotating shaft 3 is reduced, thereby avoiding the risk of breakage failure caused by weakened structural strength when the rotating shaft 3 is equipped with an air-proof structure to connect the internal circuit, significantly improving reliability and service life, maintaining the compatibility advantage of the dual-sided magnetic charging position 21 flip switching, reducing the structural precision requirements, and ensuring a stable and vibration-free charging process.

[0025] Please refer to Figure 1 Furthermore, the support base 1 is provided with a support ring 13 extending around the outer side wall of the charging assembly 2.

[0026] As described above, by having the support ring 13 surrounding the outer wall of the charging component 2 contact the annular area at the bottom of the watch, the gravity is evenly distributed to avoid stress concentration, forming a physical protective barrier to prevent external collisions and prevent users from contacting rotating parts, thereby improving safety and enhancing the visual integration with the electronic device itself.

[0027] Furthermore, when the smartwatch is wirelessly charged, the support ring directly contacts and supports the smartwatch.

[0028] As described above, by having the support ring 13 contact and support the smartwatch, the load on the rotating shaft 3 can be further reduced, thus further reducing the risk of failure.

[0029] Please refer to Figure 4 Furthermore, the auxiliary shaft 4 and the support base 1 are integrally formed as a single structure.

[0030] As described above, the auxiliary shaft 4 and the support base 1 are integrally formed, eliminating the need for separate processing and assembly, reducing the number of parts and reducing error accumulation, eliminating the connection interface to maximize structural rigidity, avoiding the risk of loosening and breakage, and eliminating the mating gap to prevent dust and liquid from seeping in, thereby improving the protection level.

[0031] Please refer to Figure 3 Furthermore, the support base 1 is provided with a connecting groove 14 and a rotating hole 15 that are connected. The connecting groove 14 is used to connect electronic devices. The rotating shaft 3 is rotatably mounted in the rotating hole 15. The rotating shaft 3 is provided with a wire-passing hole 31 that connects the connecting groove 14 and the inside of the charging component 2.

[0032] As described above, the support base 1 is provided with a connecting groove 14 that connects the electronic device and the rotating hole 15, and the rotating shaft 3 is provided with a wire hole 31, so that the connecting wire of the charging component 2 is hidden in the internal channel throughout, avoiding entanglement and wear caused by exposure. When flipping, the wire is regularly tensioned and relaxed to prevent motion interference. In addition, the connecting groove 14 can be used as a standardized interface to adapt to a variety of electronic devices.

[0033] Furthermore, the outer side wall of the rotating shaft 3 is provided with a first snap-fit ​​protrusion 32 and a second snap-fit ​​protrusion 33 on opposite sides, and the connecting groove 14 is provided with a snap-fit ​​groove 141; when one of the two magnetic charging positions 21 of the charging component 2 is vertically upward, the first snap-fit ​​protrusion 32 snaps into the snap-fit ​​groove 141; when the other magnetic charging position 21 of the two magnetic charging positions 21 of the charging component 2 is vertically upward, the second snap-fit ​​protrusion 33 snaps into the snap-fit ​​groove 141.

[0034] As described above, the outer wall of the rotating shaft 3 is provided with a first snap-fit ​​protrusion 32 and a second snap-fit ​​protrusion 33, and the connecting groove 14 is provided with a snap-fit ​​groove 141. When the charging component 2 is flipped to face any magnetic charging position 21, the corresponding snap-fit ​​protrusion and snap-fit ​​groove 141 engage, providing mechanical limit and positioning feedback to ensure accurate alignment of the magnetic pole direction, and forming a self-locking force to resist unintended flipping, while providing a tactile feel for easy status identification.

[0035] Furthermore, the connecting groove 14 is also provided with a first limiting protrusion 142 and a second limiting protrusion 143, and the outer side wall of the rotating shaft 3 is provided with a third limiting protrusion 34; when the first locking protrusion 32 is locked in the locking groove 141, the third limiting protrusion 34 abuts against the first limiting protrusion 142; when the second locking protrusion 33 is locked in the locking groove 141, the third limiting protrusion 34 abuts against the second limiting protrusion 143.

[0036] As described above, a first limiting protrusion 142 and a second limiting protrusion 143 are added inside the connecting groove 14, and a third limiting protrusion 34 is provided on the outer side wall of the rotating shaft 3. When the locking protrusions are engaged, the third limiting protrusion 34 abuts against the corresponding limiting protrusion, forming a secondary rigid limit to prevent the risk of over-rotation after the locking structure wears and fails, and to buffer the impact energy at the moment of positioning to extend the service life of the locking structure. At the same time, an additional support point is formed between the support base 1 and the rotating shaft 3 to enhance local rigidity.

[0037] Please refer to Figure 1 and Figure 2 Furthermore, both magnetic charging positions 21 are provided with an identification structure 22.

[0038] As described above, both magnetic charging positions 21 are equipped with recognition structures 22, allowing users to quickly determine the current orientation by touch or vision without having to memorize the polarity correspondence. This prevents the watch from being placed upside down and thus not fitting properly, avoids trial and error, and improves operational convenience. At the same time, it ensures polarity matching to optimize charging efficiency.

[0039] Furthermore, the identification structure 22 is a positioning groove provided in the magnetic charging position 21, and the positioning groove is used to connect with the charging contact part of the smartwatch.

[0040] As described above, the identification structure 22 uses a positioning groove that matches the shape of the watch charging contact area. It restricts the unique correct placement posture through physical structure to achieve reliable foolproofing. The side wall of the groove guides the placement process to automatically align with the center of the coil, while limiting the horizontal sliding of the watch to enhance the anti-vibration stability in conjunction with the magnetic attraction.

[0041] Please refer to Figure 5 To solve the above-mentioned technical problems, this utility model also provides an electronic device, including the above-mentioned wireless charging structure for watches.

[0042] As described above, by integrating the wireless charging structure of watches into electronic devices such as chargers, car mounts, power banks, desk lamps, or speakers, the devices can be made compatible with charging watches from multiple brands, thereby increasing added value. This also allows for the reuse of the electronic device's structure and power supply system to reduce costs, promotes the standardization of charging infrastructure, meets the needs of multiple scenarios, and reduces electronic waste.

[0043] Embodiment 1 of this utility model is as follows: Please refer to Figure 2 as well as Figure 4A wireless charging structure for watches is proposed, which is suitable for various electronic device integration scenarios that require compatibility with the different magnetic charging polarities of multiple brands of smartwatches. The support base 1 supports the weight of the watch while the hinge 3 only performs the flipping function, which significantly reduces the risk of hinge 3 failure due to internal wiring. It is especially suitable for use environments with high requirements for structural reliability and multi-device versatility, such as three-in-one wireless chargers, car mounts, power banks, desktop lamps, and audio equipment.

[0044] Specifically, the wireless charging for the smartwatch includes a charging component 2 and a rotating shaft 3. The charging component 2 rotates around the central axis of the rotating shaft 3. The charging component 2 has magnetic charging positions 21 on opposite sides for wirelessly charging the smartwatch. It also includes a support base 1 and an auxiliary shaft 4. The auxiliary shaft 4 is rotatably mounted between the support base 1 and the charging component 2. The central axis of the auxiliary shaft 4 coincides with the central axis of the rotating shaft 3.

[0045] Optionally, the auxiliary shaft 4 can be rotatably connected to the support base 1 and / or the charging component 2; alternatively, the auxiliary shaft 4 can be fixed to the support base 1 and rotatably connected to the charging component 2; or, the auxiliary shaft 4 can be fixed to the charging component 2 and rotatably connected to the support base 1; or, the auxiliary shaft 4 can be rotatably connected to both the charging component 2 and the support base 1. The specific configuration can be tailored to the specific application requirements.

[0046] The rotating shaft 3 is rotatably mounted on the support base 1. When the smartwatch is wirelessly charged, the support base 1 directly contacts the bottom of the smartwatch and supports it. The load-bearing and rotation are decoupled through functional separation: the charging component 2 rotates stably within the support base 1 with the rotating shaft 3 as the rotation center, so that one of the two magnetic charging positions 21 faces upward to adapt to smartwatches with different polarities. When the smartwatch is placed in the charging position, its bottom gravity is directly transmitted to the support surface of the support base 1 and rigidly supported by the support base 1. The rotating shaft 3 only transmits the torque required to drive the charging component 2 to rotate without bearing the bending moment and shear force generated by the weight of the watch. Thus, when the rotating shaft 3 has an open structure for circuit connection, the risk of strength failure due to structural weakening is avoided.

[0047] In detail, the support base 1 includes an upper shell 11 and a lower shell 12 connected to the upper shell 11, and the rotating shaft 3 is rotatably engaged between the upper shell 11 and the lower shell 12.

[0048] Please refer to Figure 1The support base 1 is provided with a support ring 13 extending around the outer wall of the charging component 2. The support ring 13 is formed on the upper shell 11. By having the support ring 13 around the outer wall of the charging component 2 contact the annular area at the bottom of the watch, the gravity is evenly distributed to avoid stress concentration, forming a physical protective barrier to prevent external collisions and prevent users from contacting rotating parts, thereby improving safety and enhancing the visual integration with the electronic device body.

[0049] Please refer to Figure 2 and Figure 4 In this embodiment, the auxiliary shaft 4 and the support ring 13 are integrally formed, eliminating the need for separate processing and assembly, reducing the number of parts and reducing error accumulation, eliminating the connection interface to maximize structural rigidity, avoiding the risk of loosening and breakage, and eliminating the mating gap to prevent dust and liquid from seeping in, thereby improving the protection level.

[0050] Please refer to Figure 3 The support base 1 is provided with a connecting groove 14 and a rotating hole 15. The connecting groove 14 is used to connect electronic devices. The rotating shaft 3 is rotatably mounted in the rotating hole 15. The rotating shaft 3 is provided with a wire-passing hole 31 connecting the connecting groove 14 and the interior of the charging component 2. It can be understood that the support base 1 is provided with a connecting groove 14 connecting the electronic device and the rotating hole 15, and the rotating shaft 3 is provided with a wire-passing hole 31, so that the connecting wire of the charging component 2 is completely hidden in the internal channel, avoiding tangling and wear caused by exposure. During rotation, the wire is regularly tensioned and relaxed to prevent movement interference. Furthermore, the connecting groove 14 can serve as a standardized interface to adapt to various electronic devices. Specifically, the rotating shaft 3... The outer side wall has a first snap-fit ​​protrusion 32 and a second snap-fit ​​protrusion 33 on opposite sides, and the connecting groove 14 has a snap-fit ​​groove 141. When one of the two magnetic charging positions 21 of the charging component 2 is vertically upward, the first snap-fit ​​protrusion 32 snaps into the snap-fit ​​groove 141. When the other magnetic charging position 21 of the two magnetic charging positions 21 of the charging component 2 is vertically upward, the second snap-fit ​​protrusion 33 snaps into the snap-fit ​​groove 141. In this way, mechanical limiting and positioning feedback can be provided to ensure accurate alignment of the magnetic pole direction and form a self-locking force to resist unexpected flipping, while providing an operating feel for easy status identification.

[0051] Preferably, a limiting structure is provided at the rotating shaft and / or the auxiliary shaft. The limiting structure is used to control the rotation angle of the charging component. The rotation angle is 180°. When it is necessary to switch the magnetic charging position, the charging component rotates 180° in one direction. When it is necessary to switch the magnetic charging position again, the charging component needs to be rotated 180° in the opposite direction. In this way, the charging component can be prevented from rotating infinitely around the same direction, avoiding knots or tangles in the electrical connection wires and greatly reducing the risk of electrical connection wire breakage.

[0052] Specifically, in this embodiment, the limiting structure consists of a first limiting protrusion 142 and a second limiting protrusion 143 located in the connecting groove 14 of the support base 1, and a third limiting protrusion 34 located on the outer side wall of the rotating shaft 3. When the first snap-fit ​​protrusion 32 snaps into the snap-fit ​​groove 141, the third limiting protrusion 34 abuts against the first limiting protrusion 142; when the second snap-fit ​​protrusion 33 snaps into the snap-fit ​​groove 141, the third limiting protrusion 34 abuts against the second limiting protrusion 143. It can be understood that the first limiting protrusion 142 and the second limiting protrusion 143 are added in the connecting groove 14, and the third limiting protrusion 34 is provided on the outer side wall of the rotating shaft 3. When the snap-fit ​​protrusions are engaged, the third limiting protrusion 34 abuts against the corresponding limiting protrusion, forming a secondary rigid limit to prevent the risk of over-rotation after the snap-fit ​​structure wears and fails, and to buffer the impact energy at the moment of positioning to extend the life of the snap-fit ​​structure. At the same time, an additional support point is formed between the support base 1 and the rotating shaft 3 to enhance local rigidity.

[0053] In other embodiments, the limiting structure may be a first limiting protrusion and a second limiting protrusion provided on the support base 1, and a third limiting protrusion provided on the outer side wall of the auxiliary shaft; when one of the two magnetic charging positions of the charging component is vertically upward, the third limiting protrusion abuts against the first limiting protrusion; when the other magnetic charging position of the two magnetic charging positions of the charging component is vertically upward, the third limiting protrusion abuts against the second limiting protrusion.

[0054] Please refer to Figure 1 and Figure 2 Both magnetic charging positions 21 of the charging component 2 are equipped with identification structures 22. It is understood that the identification structures 22 on both sides of the magnetic charging positions 21 allow users to quickly determine the current orientation through touch or vision without needing to memorize polarity correspondences. This prevents the watch from being placed upside down, thus avoiding trial and error and improving operational convenience. Simultaneously, it ensures polarity matching to optimize charging efficiency. Optionally, the identification structure 22 can be two different stickers, coatings, etc., attached to the magnetic charging positions 21. Specifically, in this embodiment, the identification structure 22 is a positioning groove on the magnetic charging position 21, which connects to the charging contact part of the smartwatch. The area or shape of the two positioning grooves can be set differently, using physical structure to restrict a unique correct placement posture for reliable error prevention. The sidewalls of the grooves also guide the automatic alignment with the coil center during placement, while limiting horizontal slippage of the watch to enhance vibration resistance in conjunction with the magnetic force.

[0055] Please refer to Figure 5The second embodiment of this utility model is: an electronic device. Specifically, in this embodiment, the electronic device is a three-in-one wireless charger. The three-in-one wireless charger includes a base 5, an earphone wireless charging structure 6, a support rod 7, a mobile phone wireless charging structure 8, and a watch wireless charging structure. The earphone wireless charging structure 6 is disposed on the base 5 and is used to charge smart earphones. The support rod 7 is installed on the base 5. The mobile phone wireless charging structure 8 and the watch wireless charging structure are both disposed on the top of the support rod 7. The support rod 7 has a hollow structure, through which the wires of the watch wireless charging structure and the mobile phone wireless charging structure 8 are arranged.

[0056] In other embodiments, the wireless charging structure for watches can also be integrated into electronic devices such as car mounts, power banks, desk lamps, or speakers, enabling the devices to be compatible with charging multiple brands of watches to increase added value, reuse the structure of the electronic device itself and the power supply system to reduce costs, promote the standardization of charging infrastructure, meet the needs of multiple scenarios, and reduce electronic waste.

[0057] In summary, the wireless charging structure and electronic device for watches provided by this utility model, by setting an auxiliary shaft coaxial with the rotating shaft between the support base and the charging component, makes the charging component form a simply supported beam structure with two-point support. This restrains radial movement and axial sway to enhance rotational stability, reduce fatigue wear of the rotating shaft and extend its lifespan. Thus, when the rotating shaft is equipped with a clearance structure to connect the internal circuit, the risk of fracture failure caused by weakened structural strength is avoided, significantly improving reliability and service life. It also maintains the compatibility advantage of switching between the two magnetic charging positions, reduces the structural precision requirements, and ensures a stable and undisturbed charging process.

[0058] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
