[0084] Next, the embodiments of this specification are described in detail.

[0085] At present, in the process of wireless charging, the electronic device and the charging device are generally fixed by magnetism. For electronic devices that do not have magnetic components, a shell can be placed on the electronic device, and a magnetic component can be set on the shell to fix the electronic device. However, the magnetic source itself will generate an interfering magnetic field, which seriously affects the charging effect. Therefore, it is necessary to provide a magnetic component to solve the above problem.

[0086] The present disclosure provides a housing 100 . Figure 1 is a schematic structural diagram of a housing 100 in an exemplary embodiment of the present disclosure. Figure 1 As shown, the housing 100 includes a main body 50 and a magnetic attraction assembly 30 assembled on the main body 50. The magnetic attraction assembly 30 includes a magnetic conductive member 20 and a magnetic source structure 10, one side of the magnetic source structure 10 is connected to the main body 50, and the other side of the magnetic source structure 10 is connected to the magnetic conductive member 20, and the magnetic source structure 10 includes a magnetic attraction portion 11 and at least one non-magnetic portion 12.

[0087] In this embodiment, by setting the magnetic source structure 10 and the magnetic conductive part 20 on the main body 50 of the shell 100, the shell 100 can be magnetically fixed when applied to electronic equipment and charging equipment, which is convenient and quick. The magnetic conductive part 20 is placed on one side of the magnetic source structure 10 to achieve leakage magnetic shielding. The non-magnetic part 12 is set in the magnetic source structure 10 to reduce the volume of the magnetic field. Combined with the leakage magnetic shielding of the magnetic field by the magnetic conductive part 20, the magnetic field interference can be reduced.

[0088] The magnetic source structure 10 and the magnetic conductive member 20 can be annular to optimize the magnetic field distribution and improve the fixing effect on the electronic device. In other embodiments, the magnetic source structure 10 and the magnetic conductive member 20 can also be a structure that matches the shape of the electronic device or charging device. The material of the magnetic conductive member 20 can be any magnetic conductive material such as iron.

[0089] In some embodiments, the magnetic conductive member 20 is provided with at least one first notch 22, and the magnetic conductive member 20 is disconnected at the first notch 22. Providing the first notch 22 on the magnetic conductive member 20 can prevent the magnetic conductive member 20 from being disconnected due to foreign object detection, thereby improving the charging efficiency and avoiding eddy currents generated by the closing of the magnetic conductive member 20.

[0090] In one embodiment, if Figure 2 As shown, a first notch 22 may be provided in the magnetic conductive member 20, and the magnetic conductive member 20 is disconnected at the first notch 22. In another embodiment, as shown in FIG. Figure 3 , Figure 4 As shown, two or more second notches may be provided in the magnetic conductive member 20 to divide the magnetic conductive member 20 into a plurality of sub-magnetic conductive members 21 distributed along the circumference.

[0091] In one embodiment, if Figure 5As shown, the magnetic source structure 10 and the magnetic conductive member 20 are stacked in the magnetic attraction direction, and the projection of the first notch 22 in the stacking direction covers the projection of the non-magnetic portion 12 in the stacking direction. This arrangement can prevent eddy currents from being generated on the magnetic attraction component 30, thereby causing the magnetic attraction component 30 to heat up, thereby improving the safety performance of the magnetic attraction component 30. In other embodiments, insulating glue can be provided between the magnetic conductive member 20 and the magnetic source structure 10 to prevent the magnetic source structure 10 from connecting the two ends of the first notch 22.

[0092] In one embodiment, the magnetic conductive member 20 and the magnetic source structure 10 are stacked in the magnetic attraction direction. In the stacking direction, the magnetic conductive member 20 covers the magnetic attraction portion 11, thereby improving the leakage magnetic shielding effect.

[0093] It should be noted that the first notch 22 may include a slit structure and / or a strip structure. For example, the first notch 22 is a slit structure, so that the magnetic conductive part 20 is disconnected through the slit structure, while reducing the impact on the shielding effect and structural strength of the magnetic conductive part 20. Alternatively, the first notch 22 is a strip structure, so as to match the position of the non-magnetic part 12, reduce the structural cost of the magnetic conductive part 20, and avoid the magnetic conductive part 20 from closing due to interference from other structures and position movement, thereby causing eddy currents to be generated.

[0094] It should be noted that the magnetic attraction portion 11 may be a magnetized section disposed in the magnetic source structure 10, and the non-magnetized portion 12 may be a non-magnetized section disposed in the magnetic source structure 10. Alternatively, the magnetic attraction portion 11 may be a magnetized section disposed in the magnetic source structure 10, and the non-magnetized portion 12 may include at least one second notch formed in the magnetic source structure 10.

[0095] The non-magnetic portion 12 may be a slit-shaped structure and / or a strip-shaped structure. For example, the non-magnetic portion 12 is a slit-shaped structure, so that the magnetic attraction portion 11 is disconnected through the slit-shaped structure, while reducing the shielding effect and structural strength of the magnetic conductive member 20. Alternatively, the non-magnetic portion 12 is a strip-shaped structure, so as to reduce the volume of the magnetic source and reduce the structural cost of the magnetic source structure 10.

[0096] In the above embodiment, the magnetic attraction portion 11 and the non-magnetic portion 12 may be distributed along the circumferential direction, and the magnetic attraction portion 11 is disconnected at the non-magnetic portion 12. And / or, the magnetic attraction portion 11 and the non-magnetic portion 12 are distributed along the radial direction.

[0097] The following is an exemplary description of the distribution scheme of the magnetic attraction portion 11 and the non-magnetic portion 12:

[0098] In some embodiments, the magnetic attraction portion 11 is an annular structure, and the non-magnetic portion 12 is formed in an annular region radially inside and / or outside the magnetic attraction portion 11. Figure 6As shown, the annular magnetic attraction portion 11 and the non-magnetic portion 12 located radially inside the annular magnetic attraction portion 11 form a magnetic source structure 10. The non-magnetic portion 12 can be an annular non-magnetized structure, or an annular gap located inside the magnetic attraction portion 11, so as to reduce the volume of the magnetic source through the non-magnetic portion 12, thereby reducing the magnetic source interference. Figure 7 As shown, the annular magnetic attraction portion 11 and the non-magnetic portion 12 located radially outside the annular magnetic attraction portion 11 form a magnetic source structure 10. The non-magnetic portion 12 can be an annular non-magnetized structure, or an annular gap located inside the magnetic attraction portion 11, so as to reduce the volume of the magnetic source through the non-magnetic portion 12, thereby reducing the magnetic source interference.

[0099] In this embodiment, the magnetic source structure 10 may be an integrated structure. Alternatively, when the non-magnetic portion 12 is a ring-shaped non-magnetized structure, the magnetic attraction portion 11 and the non-magnetic portion 12 of the magnetic source structure 10 may be independent structures.

[0100] In one embodiment, the magnetic source structure 10 includes a first magnetic source component 13 and a second magnetic source component 14 radially located outside the first magnetic source component 13, and at least one of the first magnetic source component 13 and the second magnetic source component 14 includes an annular magnetic attraction portion 11 and a non-magnetic portion 12 radially inside and / or outside the magnetic attraction portion 11. By providing two magnetic source components, the magnetic force can be increased and the fixing effect can be improved. In addition, the annular magnetic attraction portion 11 in the first magnetic source component 13 or the second magnetic source component 14 can ensure the attraction effect, and the non-magnetic portion 12 can reduce magnetic source interference. For example Figure 8 As shown, the first magnetic source 13 includes an annular magnetic attraction portion 11 and a non-magnetic portion 12 located radially outside the magnetic attraction portion 11 , and the second magnetic source 14 includes an annular magnetic attraction portion 11 and a non-magnetic portion 12 located radially inside the magnetic attraction portion 11 .

[0101] For example, one of the first magnetic source 13 and the second magnetic source 14 includes an annular magnetic attraction portion 11 and a non-magnetic portion 12 located radially inside and / or outside the magnetic attraction portion 11, and the other of the first magnetic source 13 and the second magnetic source 14 is an annular magnetic attraction portion 11. Fig. 9 As shown, the first magnetic source 13 includes an annular magnetic attraction portion 11 and a non-magnetic portion 12 located radially inside the magnetic attraction portion 11, and the second magnetic source 14 is an annular magnetic attraction portion 11. Fig.10 As shown, the first magnetic source 13 includes an annular magnetic attraction portion 11 and a non-magnetic portion 12 located radially outside the magnetic attraction portion 11, and the second magnetic source 14 is an annular magnetic attraction portion 11. Fig.11 As shown, the second magnetic source 14 includes an annular magnetic attraction portion 11 and a non-magnetic portion 12 located radially inside the magnetic attraction portion 11, and the first magnetic source 13 is an annular magnetic attraction portion 11. Fig.12As shown, the second magnetic source component 14 includes an annular magnetic attraction portion 11 and a non-magnetic portion 12 located radially outside the magnetic attraction portion 11 , and the first magnetic source component 13 is an annular magnetic attraction portion 11 .

[0102] In some embodiments, the magnetic source structure 10 may include a first magnetic source component 13 and a second magnetic source component 14 radially outside the first magnetic source component 13, and at least one of the first magnetic source component 13 and the second magnetic source component 14 includes a plurality of magnetic attraction portions 11 and a plurality of non-magnetic portions 12 alternately arranged in the circumferential direction. By providing a plurality of non-magnetic portions 12, the size of the magnetic source is reduced, and the influence of the magnetic attraction component 30 on the outside is reduced. The magnetic attraction portions 11 are arranged at intervals along the circumferential direction to improve the fixing effect.

[0103] For example, one of the first magnetic source 13 and the second magnetic source 14 includes a plurality of magnetic attraction portions 11 and a plurality of non-magnetic portions 12 arranged alternately, and the other of the first magnetic source 13 and the second magnetic source 14 is a non-magnetic portion 12 or a magnetic attraction portion 11. When the other is a non-magnetic portion 12, the size of the magnetic source can be reduced, and when the other is a magnetic attraction portion 11, the magnetic attraction fixing effect can be improved. Fig.13 As shown, the first magnetic source 13 includes a plurality of magnetic attraction portions 11 and a plurality of non-magnetic portions 12 arranged alternately, and the second magnetic source 14 is a non-magnetic portion 12. Fig.14 As shown, the second magnetic source component 14 includes a plurality of magnetic attraction portions 11 and a plurality of non-magnetic portions 12 that are alternately arranged, and the first magnetic source component 13 is a non-magnetic portion 12 .

[0104] like Fig.15 As shown, the first magnetic source 13 and the second magnetic source 14 each include a plurality of magnetic attraction portions 11 and a plurality of non-magnetic portions 12 that are alternately arranged, the radial projections of the magnetic source portions of the first magnetic source 13 and the second magnetic source 14 overlap, and the radial projections of the non-magnetic portions 12 of the first magnetic source 13 and the second magnetic source 14 overlap. By reducing the volume of the magnetic attraction portions 11 in the first magnetic source 13 and the second magnetic source at the same time, the size of the magnetic source is further reduced, and its interference with the inside of the electronic device is reduced. At the same time, the magnetic attraction portions 11 that are arranged in the first magnetic source 13 and the second magnetic source 14 in a counterpositioned manner ensure the attraction and fixing effect of the magnetic source structure 10 that is spaced apart in the radial direction.

[0105] like Fig.16As shown, the first magnetic source 13 and the second magnetic source 14 both include a plurality of magnetic attraction parts 11 and a plurality of non-magnetic parts 12 that are alternately arranged, the radial projections of the magnetic attraction parts 11 of the first magnetic source 13 and the non-magnetic parts 12 of the second magnetic source 14 overlap, and the radial projections of the non-magnetic parts 12 of the first magnetic source 13 and the magnetic attraction parts 11 of the second magnetic source 14 overlap. By reducing the volume of the magnetic attraction parts 11 in the first magnetic source 13 and the second magnetic source at the same time, the size of the magnetic source is further reduced, and its interference with the inside of the electronic device is reduced. At the same time, the distribution of the magnetic attraction parts 11 that are staggered in the first magnetic source 13 and the second magnetic source 14 ensures the overall circumferential attraction and fixing effect of the magnetic source structure 10.

[0106] like Fig.17 As shown, the magnetic source structure 10 includes a first magnetic source component 13 and a second magnetic source component 14 radially located outside the first magnetic source component 13, at least one of the first magnetic source component 13 and the second magnetic source component 14 includes a magnetic attraction portion 11 and a non-magnetic portion 12, and the magnetic attraction portion 11 is disconnected at the non-magnetic portion 12. Disconnecting the magnetic attraction portion 11 by a non-magnetic portion 12 can avoid the eddy current heating problem caused by the closure of the first magnetic source component 13 and / or the second magnetic source component 14, and can also reduce the volume of the magnetic attraction portion 11, while ensuring the overall attraction effect of the magnetic source structure 10.

[0107] In the above embodiment, any two magnetic attraction parts 11 in the first magnetic source 13 have the same magnetism on the same side end surface, and any two magnetic attraction parts 11 in the second magnetic source 14 have the same magnetism on the same side end surface, and the magnetic attraction parts 11 of the first magnetic source 13 and the magnetic attraction parts 11 of the second magnetic source 14 have different magnetism on the same side end surface. The magnetic assembly can automatically attract to the corresponding position under the driving force of the magnetic alignment, and the accuracy of magnetic attraction is improved when the magnetic source structure 10 is easy to process and shape.

[0108] Alternatively, at least one of the first magnetic source 13 and the second magnetic source 14 includes two magnetic attraction parts 11 with different magnetic properties on the same side end surface. The magnetic assembly can be automatically attracted to the corresponding position under the magnetic force generated by the alignment of the magnetic attraction parts 11 with different magnetic properties, thereby improving the accuracy of magnetic attraction.

[0109] In the embodiments of the present disclosure, the magnetizing direction of the magnetic attraction portion 11 is parallel to the magnetic attraction direction, or the magnetizing direction of the magnetic attraction portion 11 is parallel to the radial direction, and the present disclosure is not limited to this.

[0110] In such Fig.18In the illustrated embodiment, the magnetic source structure 10 includes a first part 15 and a second part 16 alternately arranged in the circumferential direction, the first part 15 includes a first magnetic source part 13 and a second magnetic source part 14 located radially outside the first magnetic source part 13, at least one of the first magnetic source part 13 and the second magnetic source part 14 includes a magnetic attraction part 11 magnetized in parallel to the magnetic attraction direction, and at least one second part 16 includes a magnetic attraction part 11 magnetized in parallel to the radial direction. The combination of the two magnetic pole distribution methods further improves the accuracy and reliability of the alignment magnetic attraction. The magnetic attraction direction can be the direction of the attraction force formed between the magnetic attraction part 11 and the external device when the shell 100 is fixed to the external device by attraction.

[0111] like Fig.18 As shown, the first magnetic source component 13 and the second magnetic source component 14 include a magnetic attraction portion 11 and a non-magnetic portion 12, and the magnetic attraction portion 11 is magnetized along a direction parallel to the magnetic attraction direction.

[0112] In one embodiment, in each first portion 15, the magnetizing directions of the first magnetic source components 13 when serving as the magnetic attraction portion 11 may be the same, so that the magnetic poles of the first magnetic source components 13 facing the same side of the magnetic source structure 10 when serving as the magnetic attraction portion 11 are the same. Similarly, the magnetizing directions of the second magnetic source components 14 when serving as the magnetic attraction portion 11 may be the same, so that the magnetic poles of the second magnetic source components 14 facing the same side of the magnetic source structure 10 when serving as the magnetic attraction portion 11 are the same. In other embodiments, in each first portion 15, the magnetizing directions of at least two first magnetic source components 13 when serving as the magnetic attraction portion 11 may be different, so that the magnetic poles of the corresponding magnetic attraction portion 11 facing the same side of the magnetic source structure 10 are different. Alternatively, the magnetizing directions of at least two second magnetic source components 14 when serving as the magnetic attraction portion 11 may be different, so that the magnetic poles of the corresponding magnetic attraction portion 11 facing the same side of the magnetic source structure 10 are different. The present disclosure does not limit the magnetic pole distribution when the first portion 15 serves as the magnetic attraction portion 11.

[0113] In another embodiment, the radial magnetization directions of the second parts 16 when used as the magnetic attraction part 11 can be the same. Alternatively, in other embodiments, the radial magnetization directions of at least two second parts 16 when used as the magnetic attraction part 11 can be different, and the present disclosure does not limit the magnetic pole distribution when the second parts 16 are used as the magnetic attraction part 11.

[0114] In the above embodiment, the magnetic source structure 10 can be a continuous annular structure, or the first part 15 and the second part 16 are spliced ​​along the circumferential direction to form the magnetic source structure 10. When the magnetic source structure 10 is a continuous annular structure, the magnetic source structure 10 can be obtained by controlling the magnetization position and the magnetization direction, which helps to simplify the assembly process. When the magnetic source structure 10 is formed by splicing, complex magnetization control can be avoided, which helps to simplify the processing process.

[0115] In some embodiments, Figure 1The housing 100 shown also includes an identification module 40 disposed on the main body 50, which is used to identify the identity information of the magnetic component 30, and the identification module 40 is electrically connected to at least one of the electronic device or the charging device. The identification module 40 is used to identify the identity information of the magnetic component 30. When the electronic device or the charging device detects the presence of the magnetic component 30, the electronic device or the charging device will control the charging power to avoid high-power charging causing the magnetic component 30 to heat up. The charging process can be a process in which the charging device charges the electronic device, or the electronic device reversely charges the outside world.

[0116] The specific type of the identification module 40 is not limited. For example, the identification module 40 can be an NFC (Near Field Communication) module, and the electronic device or charging device can detect the NFC module. The identification module 40 can also be a magnetic module, and the electronic device or charging device can detect the magnetic module according to the change of external inductance.

[0117] like Figure 1 As shown, the main body 50 is surrounded by a groove structure, and the groove structure matches at least a part of the electronic device and / or the charging device structure to accommodate the electronic device or the charging device. In this embodiment, the housing 100 can be used as a protective shell for the electronic device or the charging device.

[0118] The housing 100 further includes a positioning magnetic source fixed to the main body 50 for positioning the housing 100. Fig.19 As shown, the positioning magnetic source includes a rectangular structure. The rectangular structure includes a pair of first sides 61 and a pair of second sides 62, and the length of the first side 61 is greater than the second side 62. The first side 61 is arranged toward the magnetic attraction component 30. In another embodiment, as Fig. 20 As shown, the second side 62 is disposed toward the magnetic attraction assembly 30 .

[0119] In another embodiment, if Fig.21 and Fig. 22 As shown, the positioning magnetic source 60 includes at least two rectangular sub-positioning magnetic sources 601. The sub-positioning magnetic sources 601 are arranged in an array along the length direction and / or width direction of the rectangle.

[0120] The present disclosure further provides a housing, which includes: a main body 50 and a magnetic attraction assembly 30 assembled on the main body 50. The magnetic attraction assembly 30 includes a magnetic conductive member 20 and a magnetic source structure 10, one side of the magnetic source structure 10 is connected to the main body 50, and the other side of the magnetic source structure 10 is connected to the magnetic conductive member 20. Fig.23As shown, the magnetic source structure 10 includes a first part 15 and a second part 16 alternately arranged along the circumferential direction. The first part 15 includes a first magnetic source part 13 and a second magnetic source part 14 located radially outside the first magnetic source part 13, and the first magnetic source part 13 and the second magnetic source part 14 include a magnetic attraction part 11 magnetized along a direction parallel to the magnetic attraction direction. The second part 16 includes a magnetic attraction part 11 magnetized along a direction parallel to the radial direction. The combination of the two magnetic pole distribution methods further improves the accuracy and reliability of the alignment magnetic attraction. Among them, the magnetic attraction direction can be the direction of the attraction force formed between the magnetic attraction part 11 and the external device when the shell 100 is fixed by attraction with the external device.

[0121] In some embodiments, the magnetization directions of any two first magnetic source components 13 are the same, and the magnetization directions of any two second magnetic source components 14 are the same, so that the magnetic poles of the magnetic attraction portion 11 facing the same side of the magnetic source structure 10 are the same. And / or, the magnetization directions of any two second parts are the same.

[0122] In other embodiments, the magnetization directions of at least two first magnetic source components 13 are different, and the magnetization directions of at least two second magnetic source components 14 are different, so that the magnetic poles of the corresponding magnetic attraction parts 11 facing the same side of the magnetic source structure 10 are different. And / or, the magnetization directions of at least two second parts are different. It should be noted that the present disclosure does not limit the magnetic pole distribution scheme in the first part 15 and the second part 16.

[0123] The present disclosure further provides a housing 200, such as Fig.24 , Fig.25 As shown, the housing 200 includes a main body 50 and a magnetic attraction component 30 assembled on the main body 50 . The magnetic attraction component 30 includes a magnetic source structure 10 . The magnetic source structure 10 includes a magnetic attraction portion 11 and at least one non-magnetic portion 12 .

[0124] The electronic device is fixed to the charging device by the magnetism of the magnetic source structure 10 itself, thereby improving the fixing strength of the electronic device. In addition, since the magnetic source structure 10 is provided with the non-magnetic part 12, the volume of the magnetic attraction part 11 is reduced, thereby reducing the magnetic interference of the magnetic source structure 10 on components in the electronic device such as cameras, speakers, vibration motors, inductors, etc.

[0125] The present disclosure further provides an electronic device, which includes any one of the two housings 100 and 200 mentioned above.

[0126] The type of electronic device is not limited as long as it can be wirelessly charged. Specifically, the electronic device can be a mobile phone, a tablet computer, a smart bracelet, etc.

[0127] The above-mentioned shell can be used as an assembly shell of an electronic device, such as a back shell. Since the heat generated by the magnetic attraction component 30 is relatively small, the temperature of the electronic device during self-charging and external reverse charging is relatively low, the safety performance is high, and the user experience is good. In the embodiment in which the magnetic source structure 10 is provided, the fixing effect of the electronic device is better. In the embodiment in which the magnetic source structure 10 and the magnetic conductive part 20 are provided and the first notch 22 is provided on the magnetic conductive part 20, the magnetic attraction component 30 will not be detected by foreign objects, the disconnection rate of the electronic device is low, the charging efficiency of the electronic device is improved, and the user experience is optimized. The above-mentioned magnetic source structure 10 is provided with a non-magnetic part 12, which reduces the volume of the magnetic field.

The housing is a protective shell, and the housing is used to be mounted on the device body, and the housing enables the electronic device, which is not magnetic itself, to be fixed to the charging device by magnetic attraction.

[0129] The present disclosure further provides a charging device, which includes any one of the two shells mentioned above. The charging device can be any form of wireless charger. Due to the provision of the magnetic suction component 30, the electronic device can be mounted on the charging device more firmly. When the electronic device is placed on the charging device, the electronic device will be fixed to the corresponding position according to the magnetic pole. After the fixing is completed, the charging coil inside the electronic device is arranged relative to the coil of the charging device, which improves the fixing efficiency and charging efficiency and improves the user experience.

[0130] The above-mentioned shell can be used as an assembly shell of a charging device, such as an upper shell. Since the heat generated by the magnetic attraction component 30 is relatively small, the temperature of the charging device during reverse charging is relatively low, the safety performance is high, and the user experience is good. In an embodiment in which only a magnetic source structure 10 is provided, the fixing effect of the charging device is better. In an embodiment in which a magnetic source structure 10 and a magnetic conductive part 20 are provided and a first notch 22 is provided on the magnetic conductive part 20, the magnetic attraction component 30 will not be detected by foreign objects, the charging device has a low disconnection rate, the charging efficiency of the charging device is improved, and the user experience is optimized. The above-mentioned magnetic source structure 10 is provided with a non-magnetic part 12, which reduces the volume of the magnetic field. Combined with the leakage magnetic shielding of the magnetic field by the magnetic conductive part 20, the magnetic field interference can be reduced.

[0131] In one embodiment, the charging device may further include a device body. The shell is a protective shell, and the shell is used to be mounted on the device body. The shell is a protective shell, and the shell is used to be mounted on the device body, and the shell enables the charging device that is not magnetic itself to be fixed to the charging device by magnetic attraction.

[0132] When the shell is used as a shell independent of the electronic device and the charging device body 50, the body 50 may include a groove-shaped structure, which matches at least a part of the electronic device and / or the charging device structure to accommodate the charging device or the charging device.
