In this embodiment, charging

coil

12 and 11 Laser Direct Structuring (LDS) of casing to make charging

coil

12 and 11 form reliable connection, and simplify processing and the assembly process of charging coil 12, reduce charging

coil

12 and 11 connection structure's of casing occupation space. The principle of laser direct forming is to give an electrical interconnection function to a common plastic component, which generally contains metal components, and to irradiate the plastic component by using a laser technology, so that the metal in the plastic component can be precipitated, thereby forming a metal circuit or a pattern. The laser direct forming technology has the advantages of low proofing cost, convenient modification in the development process, small product volume, short design and development time, easy customization, high production efficiency and the like.

In the correlation technique, a charging coil 12 for wireless charging generally adopts the copper wire coiling to form, and the charging coil 12 that the coiling formed forms smooth sheet-like, and the both ends face of its coiling direction (be the axial) generally is the plane, and generally need through the viscose layer or separate the magnetic sheet and install to smooth structure on to reduce the thickness that charging coil 12 occupy and do benefit to the coupling in magnetic field. The magnetism isolating sheet is generally made of ferrite wave-absorbing materials, has excellent magnetic conductivity, can increase the magnetic flux of the charging coil 12 and reduce the loss of the charging coil 12, enables a magnetic induction line to tightly surround the surrounding area taking the magnetism isolating sheet as the center so as to increase the electromagnetic induction intensity, and improves the electromagnetic conversion efficiency. The connecting structures such as the adhesive layer, the magnetic separation sheet and the like all need to occupy the installation space.

And in this embodiment, because charging coil 12 laser direct forming is in shell 10, need not to carry out the coiling of charging coil 12 and the equipment of casing 11, consequently can simplify processing and the assembling process of charging coil 12, promote the efficiency of production. Adopt laser forming process to form in the charging coil 12 on casing 11 surface, need not to set up between charging coil 12 and casing 11 and be used for fixed viscose layer, also need not to set up intermediate junction spare such as magnetism sheet, consequently can save the inside installation space of equipment to the compactness that the inside device of lifting means arranged, and be favorable to the frivolous design of equipment.

Further, since the charging coil 12 is formed on the surface of the case 11 using a laser forming process, the pattern of the charging coil 12 is not limited to a planar pattern. For example, in some embodiments, the charging coil 12 is disposed on the side of the first surface 11a, the first surface 11a may include a planar area 11a1 and a curved area 11a2 connected to the planar area 11a1, and the charging coil 12 may be entirely distributed in the planar area 11a1, may extend from the planar area 11a1 to the curved area 11a2, and may be entirely distributed in the curved area 11a2 to adapt to the shape of the first surface 11a, so as to improve the utilization rate of space. In other words, the charging coil 12 on the side of the first surface 11a may be in a planar pattern or may be in a three-dimensional pattern. Planar graphics are understood to mean graphics lying substantially in the same plane, and three-dimensional graphics are understood to mean graphics having a distinction between concave or convex portions.

Referring to fig. 3 and 4, of course, in some embodiments, the charging coil 12 may be disposed on the side of the second surface 11b, the second surface 11b may also include a planar area 11b1 and a curved area 11b2 connected to the planar area 11b1, and the charging coil 12 may be entirely distributed in the planar area 11b1, may also extend from the planar area 11b1 to the curved area 11b2, and may also be entirely distributed in the curved area 11b2 to adapt to the shape of the second surface 11b, so as to improve the utilization rate of space. In other words, the charging coil 12 on the side of the second surface 11b may be in a planar pattern or may be in a three-dimensional pattern.

The distinction of the first surface 11a and the second surface 11b may be determined using the inside and the outside of the device. For example, in some embodiments, the first surface 11a is an interior surface of the device, which is generally obscured; the second surface 11b is an outer surface of the device, and the second surface 11b may be exposed to be touched by a user, or the side of the second surface 11b may be abutted to a device provided with a transmitting coil (or a receiving coil) such as a charging stand, a mobile power supply, or the like. Of course, the second surface 11b may be covered with a decorative layer such as ink or paint to beautify the appearance of the housing 10 and protect the housing 10. In this embodiment, the second surface 11b and the charging coil 12 may be hidden from view by the decoration layer, but it is still understood that the charging coil 12 is disposed on the side of the second surface 11 b.

In other embodiments, the first surface 11a and the second surface 11b may be defined by other structures. For example, referring to fig. 3, in some embodiments, the housing 11 is provided with a mounting space 11c, and the mounting space 11c may be used to house at least a portion of the components of the apparatus. The second surface 11b is located on a side of the housing 11 facing away from the installation space 11 c. Taking the case 10 as an example of an application of the smart watch, the installation space 11c may be used to accommodate devices such as a battery and a circuit board of the smart watch, and these devices may be connected to the case 11 of the case 10 to achieve the assembling location through the case 11. Taking the case 10 applied to the earphone box as an example, the installation space 11c may be used for accommodating devices such as a battery and a circuit board of the earphone box, and these devices may be connected to the housing 11 of the case 10 to achieve the assembling location through the housing 11. In such an embodiment, the first surface 11a faces the interior of the device and may therefore be referred to as the inner surface, and the second surface 11b faces the exterior and may therefore be referred to as the outer surface.

Taking the first surface 11a as the inner surface of the device, the second surface 11b as the outer surface of the device as an example, in the embodiment where the charging coil 12 is disposed on the side of the first surface 11a, compared with the scheme that the charging coil 12 is fixed by an adhesive layer or a magnetism isolating sheet in the related art, when the housing 10 abuts against the device provided with the transmitting coil (or the receiving coil) and performs wireless charging, the charging coil 12 of the embodiment of the present application may be closer to the transmitting coil (or the receiving coil), so as to reduce the electromagnetic loss in the wireless charging process and improve the efficiency of wireless charging.

Similarly, set up in the embodiment of second surface 11b place side at charging coil 12, compare in the scheme that adopts viscose layer or magnetism isolating sheet to fix charging coil 12 among the correlation technique, when shell 10 supports to the equipment that is equipped with transmitting coil (or receiving coil) and carries out wireless charging, charging coil 12 of this application embodiment also can be more close to transmitting coil (or receiving coil), thereby can reduce the electromagnetic loss in the wireless charging process, and promote wireless charging's efficiency. In this embodiment, compared with a scheme in which the charging coil 12 is disposed on the side of the first surface 11a, the charging coil 12 is also close to the transmitting coil (or the receiving coil), so that electromagnetic loss during the wireless charging process can be further reduced, and the efficiency of the wireless charging process can be further improved.

Further, since the material removal process is typically involved in the laser direct structuring process, in some embodiments, the charging coil 12 may not protrude from the same side surface of the housing 11. For example, in the embodiment in which the charging coil 12 is provided on the first surface 11a, the charging coil 12 may not protrude from the first surface 11 a. Similarly, in the embodiment where the charging coil 12 is disposed on the second surface 11b side, the charging coil 12 may not protrude from the second surface 11 b. A surface that does not protrude above may be understood as being recessed or flush with the surface. In other words, compared with the related art, under the condition that the thickness of the housing 11 is the same, the thickness of the charging coil 12 of the present embodiment can avoid overlapping with the thickness of the housing 11, and therefore the thickness of the housing 10 in the area where the charging coil 12 is located is necessarily smaller than the case where the housing 11 and the charging coil 12 overlap in the related art. Therefore, when the shell 10 of the scheme is applied to equipment with the wireless charging function, the internal installation space of the equipment occupied by the charging coil 12 can be reduced, so that the compactness of the arrangement of internal components of the equipment is improved, and the light and thin design of the equipment is facilitated.

Referring to fig. 5 and 6, in other embodiments, the first surface 11a and the second surface 11b may be provided with charging coils 12, and the charging coils 12 of the two sides are oppositely disposed. This arrangement may further increase the coupling effect of the magnetic field to improve the efficiency of wireless charging. The housing 10 of this embodiment can still save the installation space 11c inside the device compared to the arrangement of the charging coil 12 in the related art, so as to improve the compactness of the device arrangement inside the device and facilitate the light and thin design of the device.

In the embodiment where the charging coils 12 are disposed on both the first surface 11a side and the second surface 11b side, the charging coil 12 on the first surface 11a side and the charging coil 12 on the second surface 11b side may be isolated by the housing 11. In other words, the charging coil 12 on the side of the first surface 11a and the charging coil 12 on the side of the second surface 11b may be respectively conducted with the circuit board of the device. It will be appreciated that in such an embodiment, the spacing between the charging coil 12 on the side of the first surface 11a and the charging coil 12 on the side of the second surface 11b may be very small, for example less than 1 mm, so that the spacing between two opposing charging coils 12 may be set very small. The structure can improve the coupling efficiency of the magnetic field, reduce the electromagnetic loss and further improve the wireless charging efficiency.

Referring to fig. 7, in another embodiment, the housing 11 may be provided with a through hole 11d, the through hole 11d extends from the second surface 11b to the first surface 11a, a conductor 13 may be filled in the through hole 11d, and the conductor 13 is respectively conducted with the charging coil 12 on the side of the first surface 11a and the charging coil 12 on the side of the second surface 11 b. In this embodiment, in the process of forming the charging coil 12 by laser direct structuring, the housing 11 may be perforated by laser to deposit the metal component of the housing 11 in the through hole 11d, so that the charging coil 12 on the side of the first surface 11a is conducted to the charging coil 12 on the side of the second surface 11 b. Of course, the through hole 11d may be further filled with other conductors 13, such as nano silver paste, to ensure the reliability of the electrical connection between the charging coil 12 on the side of the first surface 11a and the charging coil 12 on the side of the second surface 11 b.

Further, referring to fig. 5, the charging coil 12 may be spirally disposed on the housing 11, and a terminal of an outermost circle and a terminal of an innermost circle of the charging coil 12 are respectively provided with the contact 121. The contact 121 may be used to contact a metal conductor of the circuit board, such as a metal thimble, so as to electrically connect the charging coil 12 and the circuit board, and further wirelessly charge the battery of the device by using the wireless charging coil 12. In particular, the helical shape should be understood such that a substantially helically extending pattern is obtained when the charging coil 12 is orthographically projected into the horizontal plane. For charging coils 12 distributed over a planar area 11a1 of the first surface 11a, a spiral pattern is easier to observe; for a charging coil 12 extending from the planar area 11a1 to the curved area 11a2 of the first surface 11a or distributed entirely over the curved area 11a2, a substantially helically extending pattern may be observed by projection or looking at the charging coil 12 in the winding direction of the charging coil 12. It will be appreciated that the spacing between adjacent turns of the helical charging coil 12 may be uniformly arranged, but such an arrangement is not required.

Compared with the related art, the forming process of the charging coil 12 of the shell 10 is simple and high in yield; the charging coil 12 can be integrated onto the housing 11, so that thinner and lighter products can be stacked; the coil 12 of the present application can be processed into a planar form, and can also be formed on a curved surface, thereby providing a larger shaping space for product design; moreover, the coil 12 can be manufactured by using a laser direct forming process, so that the cost for manufacturing the coil 12 can be saved, and the process of assembling the coil 12 can be saved; moreover, the charging coil 12 is arranged on the surface of the housing 11, so that the distance between the charging coil 12 and the induction coil (external transmitting coil or receiving coil) can be reduced, and the wireless charging efficiency is improved.

The following describes an application of the housing 10 to the wearable device 20 (see fig. 8 and 9) and the earphone box 30 (see fig. 11 and 12), respectively, as an example.

After the wearable device 20 is worn to the user's wrist, at least a portion of the surface of the housing 10 conforms to the user's wrist.
