This embodiment proposes a smart electronic product 1 with a wireless charging function, which includes a wearable device 10, a base 30, and a wireless charging device 40.

The wearable device 10 includes a main bead 110 and a sub-bead string 120. The shape of the main bead 110 is, for example, a bead shape, which contains various electronic components (not shown), and can implement functions such as counting the number of shaking of the main bead 110, but the invention is not limited thereto. The sub-bead string 120 is, for example, formed by connecting a plurality of beads (not labeled), and the material and structure of each bead are not limited. The main bead 110 is located between two beads of the sub-bead string 120, and is connected with a string (not labeled) to form a ring structure. The ring structure is suitable for wearing on the limbs or neck of the human body. . In one application, the main bead 110 and the bead body constituting the sub-bead string 120 may be made into the form of a bead, so that the user can wear the wearable device 10 as a bead string on his hand or on his neck. However, it is reminded that the present invention is not limited to the structure that can be formed by the main beads, sub-bead strings, or a combination thereof. For example, in other embodiments, the shapes formed by the main beads, sub-bead strings, or a combination thereof can be based on actual Uses, visual needs, or where to wear are adjusted.

The base 30 has an accommodating surface 31 at the top thereof. The accommodating surface 31 is a downwardly concave curved surface to form an accommodating groove S1. The shape of the accommodating groove S1 matches the shape of the main bead 110 described above. . The main bead 110 is adapted to be detachably accommodated in the accommodating slot S1 and has a charging position and a non-charging position. However, for a description of the charging position and the non-charging position, please refer to the subsequent description.

In addition, the base 30 also has two yielding gaps S2, which are respectively located on opposite sides of the receiving slot S1, and when the wearable device 10 is disposed on the base 30, the yielding gap S2 is located between the main bead 110 and the sub-bead string 120. (See Figure 3). In addition, the surface of the base 30 forming the yielding gap S2 is a curved surface. Thereby, when the main bead 110 is located in the accommodation groove S1, it is adjacent to the main bead 110 The bead of the child bead string 120 can be laid down through the yielding gap S2, thereby helping to improve the aesthetics of the display.

The wireless charging device 40 includes a wireless power receiving module 410 and a wireless power transmitting module 420. Specifically, in this embodiment, the main bead 110 has a first side 11 and a second side 12 opposite to each other, and the wireless power receiving module 410 is a receiving end for wireless charging, which is located in the main bead 110, and It is located closer to the first side 11. The wireless power transmitting module 420 is a transmitting end for wireless charging. It is located in the base 30 and is located closer to the receiving surface 31.

In this embodiment, the wireless power receiving module 410 and the wireless power transmitting module 420 are in the form of a coil. When the main bead 110 is correctly accommodated in the receiving slot S1 (as shown in FIG. 3), the wireless power receiving module 410 is enabled. It is close to the wireless power transmitting module 420 and kept within a predetermined distance and parallel to each other, thereby allowing the wireless power receiving module 410 and the wireless power transmitting module 420 to form a charging circuit to wirelessly charge the main bead 110. Therefore, the main bead 110 can be charged in a wireless manner, so the main bead 110 does not need to expose any contact-type power connection plugs or sockets, which helps maintain the appearance integrity of the main bead 110 and help maintain the overall improvement. Visual effects.

However, it is reminded that the present invention is not limited to the aforementioned predetermined distance, as long as it is a distance that allows the wireless power receiving module 410 and the wireless power transmitting module 420 to form a charging circuit, all fall within the scope of the predetermined distance.

It should be emphasized that since the wearable device 10 of the smart electronic product 1 of this embodiment uses the wireless charging device 40 to charge the main bead 110, the space occupied by the charging structure in the main bead 110 is small. Compared with conventional wearable electronic products using a larger pogo pin module, the volume of the main bead 110 of the present invention can be relatively small, which helps the overall design of the smart electronic product 1.

In addition, in order to ensure that the main bead 110 can still be wirelessly charged with a slight misalignment, the wireless power receiving module 410 needs to be at least slightly smaller than the wireless power transmitting module 420.

Specifically, please refer to FIG. 5, which is a partially enlarged view of FIG. 4. In this embodiment, the width w1 of the wireless power receiving module 410 is smaller than the width of the wireless power transmitting module 420 Degree w2. This can ensure that the wireless power receiving module 410 falls within the effective power transmission range of the wireless power transmitting module 420 when the main power source 110 is slightly misaligned and the wireless power receiving module 410 is not level with the wireless power transmitting module 420. Formation of the charging circuit.

In addition, please refer to FIG. 4 again, in order to ensure that the main bead 110 is correctly placed on the base 30 for wireless charging, the smart electronic product 1 of this embodiment further includes a first magnet group 50 and a second magnet group 60 And a third magnet group 70.

The first magnet group 50 includes a first magnet 510 and a second magnet 520 with different magnetic poles, and the second magnet group 60 includes a third magnet 610 and a fourth magnet 620 with different magnetic poles, wherein the first magnet 510 The magnetic poles of the third magnet 610 are the same, and the magnetic poles of the second magnet 520 and the fourth magnet 620 are the same. In this embodiment, the magnetic poles of the first magnet 510 and the third magnet 610 are, for example, S poles, and the magnetic poles of the second magnet 520 and the fourth magnet 620 are, for example, N poles, but the present invention is not limited thereto. Therefore, when the first magnet 510 is close to the second magnet 520 or the fourth magnet 620, or the third magnet 610 is close to the second magnet 520 or the fourth magnet 620, magnetic phase attraction occurs.

Looking further, the first magnet 510 and the third magnet 610 are located in the main bead 110 and are located near the first side 11. The wireless power receiving module 410 is located between the first magnet 510 and the third magnet 610. The first magnet 510 and the third magnet 610 are symmetrically disposed through the threading hole H of the main bead 110. Therefore, when the main bead 110 rotates around the threading hole H as an axis (therefore, the threading hole H can also be seen as the axis of rotation of the main bead 110), the first magnet 510, the third magnet 610, and the wireless power receiving module 410 also rotate. It will also rotate around the threading hole H as the axis of rotation.

On the other hand, the second magnet 520 and the fourth magnet 620 are located in the base 30 and near the accommodating surface 31. The wireless power transmitting module 420 is interposed between the second magnet 520 and the fourth magnet 620.

The third magnet group 70 includes a fifth magnet 710 and a sixth magnet 720 with the same magnetic poles. In this embodiment, the magnetic poles of the fifth magnet 710 and the sixth magnet 720 are the same as the magnetic poles of the second magnet 520 and the fourth magnet 620, for example, they are all N poles. So when the fifth When the magnet 710 approaches the second magnet 520 or the fourth magnet 620, or the sixth magnet 720 approaches the second magnet 520 or the fourth magnet 620, magnetic repulsion occurs.

Looking further, the fifth magnet 710 and the sixth magnet 720 are located in the main bead 110 and near the second side 12. Furthermore, the fifth magnet 710 and the sixth magnet 720 are symmetrically disposed with the threading hole H of the main bead 110, and the fifth magnet 710 and the sixth magnet 720 are substantially respectively connected to the first magnet 510 and the third magnet on the other side. The magnets 610 are oppositely disposed. Therefore, similarly, when the main bead 110 rotates around the threading hole H as the axis, the fifth magnet 710 and the sixth magnet 720 also rotate around the threading hole H as the axis of rotation. .

First, for example, as shown in FIG. 4, when the main bead 110 is to be accommodated in the accommodating slot S1, at this time, the first magnet 510 and the second magnet 520 of the first magnet group 50 generate magnetic attraction, and the first The third magnet 610 and the fourth magnet 620 of the two magnet groups 60 generate magnetic forces to attract each other, and these attracting forces can position the main bead 110 on the base 30. And in design, when the first magnet group 50 and the second magnet group 60 are magnetically attracted to position the main bead 110, the wireless power receiving module 410 is substantially horizontal to the wireless power transmitting module 420, so that the wireless power receiving module The group 410 and the wireless power transmitting module 420 may form a charging circuit to wirelessly charge the main bead 110. That is, the main bead 110 can be positioned at the charging position by the magnetic attractive force generated by the first magnet group 50 and the second magnet group 60.

It is worth noting that even if the user does not accurately place the main bead 110 in the receiving slot S1 as shown in FIG. 4, the main bead 110 can still be corrected by the first magnet group 50 and / or the second magnet group 60. Its location.

For example, please refer to FIG. 6, which is a usage scenario diagram of the charging operation of the smart electronic product of FIG. 1. As shown in the figure, when the main bead 110 is placed in the accommodation slot S1 in a slightly skewed manner, at this time, the wireless power receiving module 410 and the wireless power transmitting module 420 are misaligned or exceed the distance capable of transmitting electric energy, which results in The main bead 110 is located in a non-charging position, but the main bead 110 can be guided back by the magnetic attraction between the first magnet 510 and the second magnet 520 of the first magnet group 50 (as shown by arrow A1) in FIG. 4 described above.示 的 位置。 Show location. That is, it is slightly skewed to a non-charged position The main bead 110 can be automatically guided from the non-charged position to the charged position by the magnetic attractive force of the first magnet group 50 and / or the second magnet group 60.

Alternatively, when the user intentionally or unintentionally puts the main bead 110 into the accommodation slot S1 in a reverse direction or with a large position deviation, the main bead 110 may remind the user and assist it automatically with the help of the third magnet group 70 Correct.

For example, please refer to FIG. 7. FIG. 7 is another usage scenario diagram of the charging operation of the smart electronic product of FIG. 1. As shown in the figure, when the user places the main bead 110 into the accommodating slot S1 with the second side 12 facing the charging base 30, the main bead 110 is also in the non-charging position at this time, but because the third magnet group 70 The magnetic poles of the fifth magnet 710 and the sixth magnet 720 are the same as those of the first magnet 510 and the fourth magnet 620. Therefore, a magnetic repulsive force is generated between the main bead 110 and the base 30 and the main bead 110 is turned (such as arrow A2). (Or A3), so that the main bead 110 can be rotated from the non-charging position to the charging position, and then the main bead 110 can be returned to the position shown in FIG. 4.

It can be known that, by setting the first magnet group 50 to the third magnet group 70 described above, it is convenient for the user to complete the action of wireless charging, and the problem of the user not turning on the wireless charging function due to incorrect placement can be avoided.

Compared with the conventional smart electronic products that are directly plugged with pogo pins for charging, the smart electronic product 1 of the present invention can smoothly complete the charging operation without requiring the user to accurately align.

In addition, please refer to FIGS. 1 and 3 again. The smart electronic product 1 further includes a visual pattern 80 on the surface of the second side 12 of the main bead 110. More specifically, the position of the visual pattern 80 is substantially opposite to the wireless power receiving module 410, and the main bead 110 has a hollow structure at the visual pattern 80, so that the light-emitting element (not shown) in the main bead 110 is provided. ) Light is transmitted through the visual pattern 80 to produce visual effects such as colored light or light and shadow changes. In addition, the visual pattern 80 also functions as an indicator to let the user know the direction of the main bead 110 or let the user know the progress of charging.

Finally, it should be stated that although the smart electronic product 1 in the foregoing embodiment includes the first magnet group 50, the second magnet group 60, and the third magnet group 70 at the same time, the present invention does not Not limited to this, in fact, the second magnet group 60 and the third magnet group 70 are selected. For example, in other embodiments, the smart electronic product may omit the second magnet group 60 and the third magnet group 70 and retain only the first magnet group 50. In addition, the present invention is not limited to the magnetism of each of the foregoing magnet groups. As long as the relationship between the polarities in each of the magnet groups satisfies the aforementioned requirements, it belongs to the scope of the present invention.

To sum up, the above-mentioned smart electronic products use wireless charging to charge their main beads, so they occupy less space in the main beads, which helps reduce the size of the main beads and reduce the size of wearable devices. The overall volume. In addition, wireless charging does not need to be plugged in to form a charging circuit, so the appearance of the main bead does not need to expose any connectors to maintain integrity.
