Description

Technical Field

[0001] The present application relates to the field of wireless charging, and in particular to magnetic wireless charging components and devices. Background Art

[0002] The main components of a traditional magnetic wireless charging device include a magnet assembly and a coil. For example, in a magnetic wireless charging device, the magnet assembly is approximately 2mm thick, while the coil is approximately 1.2mm thick, meaning the magnet assembly is 0.8mm taller than the coil. This results in wasted space, as the magnet assembly is thicker than the coil, creating redundant thickness in the overall product structure. This results in a non-compact and bulky structure for traditional magnetic wireless charging devices.

[0003] In order to solve this problem, in order to achieve a compact structure and a small overall volume, a conventional magnetic wireless charging device generally adopts a method of providing a mounting groove on the upper cover and placing a magnet group therein.

[0004] However, it was found in actual products that this would bring new problems: low product reliability and magnetic performance that did not meet the requirements. The specific explanations are as follows.

[0005] First, to ensure the product's magnetic attraction performance, a sufficiently deep mounting slot must be created in the top cover without changing the thickness of the magnet assembly. However, due to the thinness of the top cover, creating a sufficiently deep mounting slot in such a thin cover would significantly reduce product reliability. This issue is particularly severe for ultra-thin product designs.

[0006] Second, to ensure product reliability, a mounting slot was provided on the upper cover; the depth of the mounting slot ensured product reliability, and the thickness of the magnet assembly was reduced. However, this reduced thickness resulted in the magnet assembly's magnetic attraction performance failing to meet product requirements. Utility Model Content

While achieving a compact product structure and a small overall volume, it ensures that the product meets the requirements of magnetic performance and the product has high reliability; on the other hand, it is conducive to adjusting the thickness of the magnetic component to achieve an ultra-thin product design under the premise of ensuring that the product meets the magnetic performance; on the other hand, it is conducive to reducing the thickness of the magnetic component under the premise of ensuring product reliability, and providing sufficient magnetic adsorption function for the objects to be adsorbed on the outer surface. The following is combined with Figures 1 to 14 , the magnetic wireless charging component and device are described in detail.

[0057] In one embodiment, a magnetic wireless charging device 900 is as follows: Figure 1 As shown, it includes a main body 200 and a magnetic wireless charging component 100, and the magnetic wireless charging component 100 is connected to the main body 200. The magnetic wireless charging component 100 is the magnetic wireless charging component 100 described in any embodiment of this document.

[0058] As an example, the magnetic wireless charging component 100 is covered on the main body 200. It can also be understood that the main body 200 has a shell, and the magnetic wireless charging component 100 is covered on the shell, so that the functional components of the main body 200 arranged in the shell are enclosed by the magnetic wireless charging component 100 and the shell, that is, the magnetic wireless charging component 100 and the shell together form a closed box body, and the functional components of the main body 200 arranged in the shell are all enclosed in the box body.

[0059] As an example, combined with Figure 5 The magnetic wireless charging component 100 is provided with a coil 130 for wireless charging, and the coil 130 of the magnetic wireless charging component 100 is conductively connected to the battery of the main body 200, and is used to emit an electromagnetic signal under the action of electricity, so that the terminal to be charged, such as the mobile terminal to be charged, receives the electromagnetic signal and converts the electromagnetic signal into current, thereby realizing wireless charging for the mobile terminal.

[0060] In one embodiment, a magnetic wireless charging device 900 is as follows: Figure 2 As shown, Figure 1 Unlike the illustrated embodiment, in this embodiment, the magnetic wireless charging assembly 100 of the magnetic wireless charging device 900 is further provided with an identification position 114 for identifying the position of the coil 130. In other words, the identification position 114 is used to identify the wireless charging position of the coil 130. This design facilitates accurate use of the magnetic wireless charging device 900.

[0061] In one embodiment, a magnetic wireless charging device 900 is as follows: Figure 3 As shown, Figure 2 Unlike the illustrated embodiment, the magnetic wireless charging device 900 also includes a charging cable 300, the ends of which are pluggably connected to the two ports of the main body 200. This design facilitates storage of the charging cable 300 and protects both ends of the charging cable 300 when not in use. It also protects the two ports of the main body 200, providing a certain degree of protection.

[0062] In one state of use, one end of the charging cable 300 is connected to a port of the main body 200, and the other end is connected to a power source or a power adapter, for charging the battery of the main body 200 of the magnetic wireless charging device 900. In another state of use, one end of the charging cable 300 is connected to a port of the main body 200, and the other end is connected to the terminal to be charged, and the magnetic wireless charging device 900 charges the terminal to be charged through the charging cable 300. In yet another state of use, the two ends of the charging cable 300 are respectively connected to the two ports of the main body 200, or the two ends of the charging cable 300 are pulled out from the two ports of the main body 200, that is, the two ends of the charging cable 300 are not connected to the two ports of the main body 200, the magnetic wireless charging device 900 does not work, or the magnetic wireless charging device 900 charges the terminal to be charged in a wireless charging manner through the coil 130.

[0063] In one embodiment, a magnetic wireless charging component 100 is as follows Figure 4 and Figure 5 As shown, the magnetic wireless charging assembly 100 includes a cover 110, a magnetic assembly 120, and a coil 130; the magnetic assembly 120 and the coil 130 are both disposed on the cover 110. As an example, the cover 110 has an outer surface 111 and an inner surface 112 facing each other. Exemplarily, the outer surface 111 faces the outside, and the inner surface 112 faces the main body 200.

[0064] like Figure 5 As shown, the magnetic component 120 and the coil 130 are arranged on the inner surface 112 of the cover 110, and the magnetic component 120 is arranged outside the coil 130; the magnetic component 120 is configured to magnetically attract the object to be attracted on the outer surface 111. Exemplarily, the magnetic attraction force of the magnetic component 120 for the object to be attracted on the outer surface 111 reaches more than 13N. Such a structural design is conducive to changing the thickness of the magnetic component 120 to achieve an ultra-thin product design while ensuring that the product meets the magnetic attraction performance. That is, while achieving a compact product structure and a small overall volume, it can ensure that the product meets the magnetic attraction performance requirements. Among them, the object to be attracted includes but is not limited to the back shell of the terminal to be charged, magnetic accessories or iron sheets, etc., so that the terminal to be charged is positioned on the cover 110, and then the magnetic wireless charging device 900 can charge the terminal to be charged in a wireless charging manner through the coil 130.

[0065] In various embodiments, the magnetic component 120 is configured to magnetically attract an object to be attracted on the outer surface 111, and the magnetic component 120 has a shape that is at least partially annular, and the inner edge 121 of the magnetic component 120 is adapted to the outer edge of the coil 130. As an example, the magnetic component 120 has a shape that is at least partially annular, including the magnetic component 120 being annular as a whole, the magnetic component 120 being partially annular, the magnetic component 120 being a portion of a complete ring, and the magnetic component 120 being a portion of a complete ring. For the partial ring, the partial ring has a certain ring width, which can also be called width, that is, the magnetic component 120 has a certain ring width. The outer edge 122 of the magnetic component 120 is configured to extend outward to increase the ring width of the magnetic component 120, so that when the magnetic component 120 magnetically absorbs the object to be absorbed on the outer surface 111, the thickness difference between the magnetic component 120 and the coil 130 is lower than a preset thickness; wherein the preset thickness is less than or equal to 0.3 mm. As an example, the ring width of the magnetic component 120 is configured so that when the magnetic component 120 magnetically attracts an object on the outer surface 111, the difference in thickness between the magnetic component 120 and the coil 130 is less than a preset thickness. Since the thickness, or height, of the magnetic component 120 is reduced, the outer edge 122 of the magnetic component 120 needs to extend outward to increase the ring width of the magnetic component 120, thereby enhancing the magnetic attraction force of the magnetic component 120, ensuring that the magnetic component 120 can magnetically attract the object on the outer surface 111, thereby ensuring that the magnetic wireless charging device 900 can wirelessly charge the object via the coil 130. This structural design, by adjusting the ring width of the magnetic component 120 to achieve the magnetic attraction function, and by designing the thickness difference between the magnetic component 120 and the coil 130, reduces the thickness of the magnetic component 120 while ensuring product reliability, and provides sufficient magnetic attraction for the object on the outer surface 111.

[0066] Compared with traditional magnetic components, as an example, the magnetic component 120 described in the present application is thinned and widened at the same time, so as to increase the ring width while reducing the thickness to maintain a certain magnetic adsorption force, ensuring that the magnetic component 120 can magnetically adsorb the object to be adsorbed on the outer surface 111, thereby realizing the designed wireless charging function.

[0067] For example, Figure 6 and Figure 7As shown, the thickness H1 of the magnetic assembly 120 and the thickness H2 of the coil 130 have a thickness difference H3, and the thickness difference H3 is less than the predetermined thickness. In one embodiment, the predetermined thickness is less than or equal to 0.3 mm. As an example, the predetermined thickness is 0.25 mm, 0.28 mm, or 0.3 mm. As described in the background technology, this is because the thickness of the magnetic component 120 is usually much higher than the thickness of the coil 130, resulting in redundant thickness in the product structure. On the premise of keeping the thickness of the coil at about 1.2 mm unchanged, the thickness of the magnetic component 120 is reduced from 2 mm to the preset thickness less than or equal to 0.3 mm. As an example, the thickness of the magnetic component 120 is less than or equal to 1.5 mm; exemplarily, the thickness of the corresponding coil is about 1.2 mm, and the thickness of the magnetic component 120 is 0.9 mm to 1.5 mm. exemplarily, the thickness of the magnetic component 120 is 1.2 mm to 1.5 mm. Accordingly, in this state, the ring width of the magnetic component 120 needs to be increased. As an example, the ring width of the magnetic component 120 is greater than or equal to 58 mm relative to the ring width of 56 mm or other widths before the thickness adjustment, so as to enhance the magnetic adsorption force of the magnetic component 120. That is, the thickness of the magnetic component 120 is reduced according to the requirement of the preset thickness, so that the thickness difference between the magnetic component 120 and the coil 130 is lower than the preset thickness. However, since the thickness of the magnetic component 120 is reduced, the magnetic adsorption force of the magnetic component 120 is reduced. Therefore, the ring width of the magnetic component 120 is appropriately increased to enhance the magnetic adsorption force of the magnetic component 120 and compensate for the magnetic adsorption force decreased due to the reduction of the thickness of the magnetic component 120. In this way, under the premise of reducing the thickness of the magnetic component 120, the magnetic component 120 is ensured to be roughly flush with the coil 130, and the magnetic attraction is maximized. The internal space of the magnetic wireless charging component 100 is reduced, which is conducive to reducing the thickness of the product. While achieving a compact product structure and a small overall volume, it ensures that the product meets the requirements of magnetic attraction performance and has high reliability. That is, by compensating for the magnetic attraction force that decreases due to reducing the thickness of the magnetic attraction component 120, it is ensured that the magnetic attraction component 120 can magnetically attract the object to be attracted on the outer surface 111, thereby ensuring the wireless charging function of the magnetic wireless charging component 100 and the magnetic wireless charging device 900 using the magnetic wireless charging component 100 for the terminal to be charged, such as a mobile terminal to be wirelessly charged.

[0068] In one embodiment, Figure 8 and Figure 9 As shown, the magnetic component 120 is arranged outside the coil 130; as an example, the magnetic component 120 and the cover 110 are combined in an embedded manner. Figure 10The cover 110 has a first mounting groove 115 on its inner surface 112, and the magnetic component 120 is embedded therein. In other embodiments, the cover 110 and the magnetic component 120 can also be assembled and installed by injection molding or snap-fitting.

[0069] In one embodiment, Figure 10 As shown, the cover 110 is provided with a first mounting groove 115 and a second mounting groove 116 on its inner surface 112, wherein the first mounting groove 115 is arranged outside the second mounting groove 116; the magnetic assembly 120 is at least partially accommodated in the first mounting groove 115, and the coil 130 is at least partially accommodated in the second mounting groove 116; or, the magnetic assembly 120 is accommodated in the first mounting groove 115, the coil 130 is accommodated in the second mounting groove 116, and the depth difference between the first mounting groove 115 and the second mounting groove 116 is equal to the predetermined thickness. Such a structural design is not only conducive to positioning and installing the magnetic assembly 120 and the coil 130, but also conducive to increasing the structural strength of the cover 110, and is particularly suitable for the cover 110 made of plastic.

[0070] Combined Figure 7 For example, the depth of the first mounting groove 115 is equal to the thickness H1 of the magnetic component 120. In this state, the magnetic component 120 is completely accommodated in the first mounting groove 115; similarly, the depth of the second mounting groove 116 is equal to the coil thickness H2 of the coil 130. In this state, the coil 130 is completely accommodated in the second mounting groove 116. The depth difference between the first mounting groove 115 and the second mounting groove 116 is equal to the thickness difference H3. When the thickness difference H3 is equal to the preset thickness, the depth difference between the first mounting groove 115 and the second mounting groove 116 is equal to the preset thickness.

[0071] In one embodiment, a magnetic wireless charging component 100 includes a cover 110, a magnetic component 120 and a coil 130; the cover 110 has an outer surface 111 and an inner surface 112 opposite to each other, the magnetic component 120 and the coil 130 are arranged on the inner surface 112 of the cover 110, and the magnetic component 120 is arranged around the coil 130; the magnetic component 120 is configured to magnetically attract an object to be attracted on the outer surface 111, and the magnetic component 120 has an at least partially annular shape, and the inner edge 121 of the magnetic component 120 is adapted to the outer edge of the coil 130; the magnetic component 120 is arranged on the inner surface 112 of the cover 110 by injection molding, so that when the magnetic component 120 magnetically attracts the object to be attracted on the outer surface 111, the height difference between the magnetic component 120 and the coil 130 is lower than a preset height; wherein the preset height is less than or equal to 0.3 mm. As an example, the magnetic assembly 120 only includes the magnetic member 123. This structural design, because the magnetic assembly 120 is injection-molded into the cover 110, makes the magnetic assembly 120 and the cover 110 form a single unit in appearance, which helps to further simplify the structure of the magnetic assembly 120, thereby helping to reduce the height of the magnetic assembly 120, thereby ensuring that the magnetic assembly 120 is roughly flush with or even completely flush with the coil 130, thereby reducing the thickness of the product.

[0072] In one of the embodiments, the thickness of the magnetic component 120 is less than or equal to 1.5 mm. As an example, the thickness of the magnetic component 120 is 1.2 mm, 1.32 mm, 1.38 mm, 1.45 mm or 1.5 mm. In one of the embodiments, the ring width of the magnetic component 120 is greater than or equal to 58 mm. As an example, the ring width of the magnetic component 120 is 58 mm, 59 mm, 60 mm or 62 mm. Exemplarily, the ring width of the magnetic component 120 is set according to the thickness of the magnetic component 120. As an example, the ring width of the magnetic component 120 is inversely proportional to the thickness of the magnetic component 120. In one of the embodiments, the thickness of the magnetic component 120 is 1.2 mm, and the ring width of the magnetic component 120 is 58 mm. The remaining embodiments are similar and will not be described in detail.

[0073] The following describes an embodiment of providing mounting grooves on the cover 110 and embedding the magnetic assembly 120 therein, in conjunction with a design for a specific application. Taking the above example where the thickness of the magnetic assembly 120 is 1.5 mm and the thickness of the coil 130 is 1.2 mm, a groove is formed on the cover 110, and the coils 130 of the magnetic assembly 120 are embedded therein; wherein the depth of the first mounting groove 115 in the area corresponding to the cover 110 and the magnetic assembly 120 is 1.5 mm, and the depth of the second mounting groove 116 in the area corresponding to the cover 110 and the coil 130 is 1.2 mm, i.e., the difference in depth between the two grooves is 0.3 mm. In this way, the magnetic component 120 can be ensured to be flush with the coil 130, thereby maximizing the use of the space of the magnetic wireless charging device 100. Moreover, since the area of ​​the coil 130 is larger than the area of ​​the magnetic component 120, the depth of the second mounting groove 116 in the area corresponding to the coil 130 is set to be shallower than the depth of the first mounting groove 115 in the area corresponding to the magnetic component 120, which can better ensure the reliability of the product.

[0074] In one embodiment, Figure 8 and Figure 11 As shown, the inner edge 121 of the magnetic component 120 is adapted to the arrangement of the coil 130, and the ring width of the magnetic component 120 is configured so that the outer edge 122 of the magnetic component 120 extends outward for expansion. That is, when the ring width of the magnetic component 120 is increased, the inner edge 121 of the magnetic component 120 remains unchanged to avoid affecting the coil 130, thereby requiring additional design of the parameters of the coil 130 and related production processes; the outer edge 122 of the magnetic component 120 is expanded outward to achieve the increase in the ring width of the magnetic component 120; Figure 11 and Figure 12 As shown, the shape of the magnetic component 120 is roughly similar to a ring, and can also be a partial ring. When the ring width of the magnetic component 120 is set, that is, when the ring width of the magnetic component 120 is configured, that is, when the ring width of the magnetic component 120 is increased, the inner diameter of the partial ring remains unchanged, and the outer diameter increases, so that the outer edge 122 of the magnetic component 120 extends outward for expansion. Figure 13 The dotted line represents the outer edge 122 of the magnetic assembly 120 before widening. The outer edge 122 of the magnetic assembly 120 after widening is located outside the dotted line. This structural design helps ensure that the product meets the magnetic attraction performance requirements, that is, ensures that the magnetic assembly 120 magnetically attracts the object to be attracted on the outer surface 111, thereby achieving the wireless charging function.

[0075] In one embodiment, Figure 13As shown, when the preset thickness is 0.3 mm and the thickness of the coil 130 is 1.2 mm, the thickness of the magnetic component 120 needs to be adjusted to less than 1.5 mm, for example, the thickness of the magnetic component 120 is adjusted from 2 mm to about 1.5 mm. In order to ensure that the magnetic component 120 can magnetically adsorb the object to be adsorbed on the outer surface 111, the ring width of the magnetic component 120 needs to be increased. As mentioned above, for the magnetic component 120 having a partial annular shape, while ensuring that the inner circle diameter remains unchanged, the diameter of the outer circle is increased, thereby increasing the ring width of the magnetic component 120; as an example, the outer diameter of the magnetic component 120 is adjusted from 56 mm to about 58 mm, thereby reducing the thickness of the magnetic component 120 while increasing the ring width of the magnetic component 120, thereby ensuring that the magnetic component 120 can magnetically adsorb the object to be adsorbed on the outer surface 111.

[0076] In one embodiment, Figure 11 As shown, the magnetic attraction assembly 120 includes a magnetic member 123 and an assembly sheet 124; Figure 12 and Figure 14 , the magnetic part 123 is magnetically adsorbed on the assembly piece 124, and the magnetic part 123 is located between the assembly piece 124 and the cover body 110. As an example, the assembly piece 124 is an iron sheet, so that the magnetic part 123 can be magnetically adsorbed on the assembly piece 124. In this embodiment, the contour shape of the magnetic part 123 is the same as the contour shape of the assembly piece 124, that is, after the assembly is completed, the magnetic part 123 completely overlaps with the assembly piece 124, and the projections of the two on a certain plane coincide with each other. In other embodiments, the contour shape of the magnetic part 123 may also be larger than the contour shape of the assembly piece 124, that is, on a certain plane, the projection of the magnetic part 123 covers the projection of the assembly piece 124 and is larger than the projection of the assembly piece 124.

[0077] For the magnetic attraction assembly 120 having a magnetic member 123 and an assembly piece 124, in one embodiment, the number of the magnetic member 123 is one, and the contour shape of the magnetic member 123 is the same as the contour shape of the assembly piece 124, or the contour shape of the magnetic member 123 is larger than the contour shape of the assembly piece 124; or, in one embodiment, as Figure 11 and Figure 12As shown, the magnetic assembly 120 includes a mounting plate 124 and a plurality of magnetic members 123. The plurality of magnetic members 123 form a ring, and the mounting plate 124 is attached to one side of the ring. The mounting plate 124 fits within the ring formed by the plurality of magnetic members 123. In this embodiment, the thickness of the magnetic assembly 120 is the sum of the thicknesses of the mounting plate 124 and the magnetic members 123. The outer diameter refers to the outer diameter of the ring formed by the mounting plate 124 or the plurality of magnetic members 123.

[0078] In one embodiment, Figure 12 and Figure 13 As shown, there are multiple magnetic members 123, each of which is magnetically attached to the assembly sheet 124. The overall outline of all of the magnetic members 123 is the same as the outline of the assembly sheet 124. In other embodiments, the overall outline of all of the magnetic members 123 may be larger than the outline of the assembly sheet 124. The assembly sheet 124 not only positions and combines the multiple magnetic members 123, but also facilitates isolation of other components in the main body 200 when necessary.

[0079] In other embodiments, the assembly piece 124 may not be provided, and the position of the magnetic assembly 120, which only includes at least three regularly arranged magnetic members 123, may be restricted by the first mounting groove 115 or other structures. In one embodiment, the magnetic assembly 120 is provided on the inner surface 112 of the cover 110 by injection molding. In this way, the magnetic assembly 120 and the cover 110 are integrally formed in appearance; that is, when the cover 110 is formed, the magnetic assembly 120 can be placed therein, and the final form is that the magnetic assembly 120 is covered by the material forming the cover 110. The material forming the cover 110 may partially cover the magnetic assembly 120, or it may completely cover the magnetic assembly 120. It should be noted that the position of the magnetic assembly 120 in the cover 110, as well as the parameters of the ring width and outer diameter of the magnetic assembly 120 need to be controlled to meet the requirements, and can be set with reference to the previous embodiment.

[0080] In one embodiment, the magnetic assembly 120 is injection molded onto the inner surface 112 of the cover 110 ; further, the magnetic assembly 120 includes only the magnetic member 123 , i.e., the magnetic assembly 120 does not include the mounting plate 124 or other structural components. In one embodiment, the magnetic assembly 120 is injection molded onto the inner surface 112 of the cover 110 ; further, the magnetic assembly 120 includes only at least three magnetic members 123 arranged in a regular pattern. The remaining embodiments are similar and are not further described. Such a design, on the one hand, for an embodiment in which the magnetic component 120 is arranged on the inner surface 112 of the cover body 110 by injection molding, the magnetic component 120 can be integrally formed with the cover body 110 in appearance by injection molding. On the other hand, for an embodiment in which the assembly sheet 124 is not adopted, that is, an embodiment in which the magnetic component 120 only includes at least three magnetic parts 123 arranged in a regular pattern, the thickness of the magnetic component 120 can be further controlled or adjusted by abandoning the assembly sheet 124. On the basis of increasing the ring width of the magnetic component 120, it is beneficial to improve the magnetic adsorption force of the magnetic component 120, thereby improving the magnetic fixing effect of the magnetic component 120 on the object to be adsorbed on the outer surface 111; and on the basis of not increasing or only slightly increasing the ring width of the magnetic component 120, the magnetic adsorption force of the magnetic component 120 can be guaranteed, thereby ensuring the magnetic fixing effect of the magnetic component 120 on the object to be adsorbed on the outer surface 111.
