Description

Technical Field

[0001] This disclosure relates to the field of terminal technology, and in particular to a magnetic protective sleeve and a device module. Background Technology

[0002] Magnetic protective cases are popular among users because they allow for quick and stable detachable connection to bases or charging docks. However, when electronic devices are assembled inside the magnetic protective case, the projection of the magnet inside the case is likely to overlap with the near-field antenna radiator inside the electronic device. This significantly impacts the performance of the near-field antenna radiator and affects the near-field communication performance of the electronic device. Utility Model Content

[0011] Magnetic protective sleeve as described in any of the foregoing embodiments;

[0012] An electronic device, which is detachably assembled to the magnetic protective sleeve, includes a near-field antenna radiator, and the metal component is located between the near-field antenna radiator and the magnetic component in the thickness direction of the electronic device.

[0013] Optionally, the distance between the metal part and the near-field antenna radiator is greater than or equal to 0.5 mm and less than or equal to 1 mm;

[0022] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0023] As can be seen from the above embodiments, after the magnetic protective sleeve of this disclosure is assembled with the electronic device, the metal part can be set relatively close to the near-field antenna radiator of the electronic device. When the near-field antenna radiator is excited by current, the metal part can couple with the near-field antenna radiator to improve the radiation performance of the near-field antenna radiator, thus taking into account both the near-field communication performance and the magnetic attraction effect of the magnetic protective sleeve.

[0031] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0032] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The singular forms “a,” “the,” and “the” as used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0033] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0034] Figure 1 This is a schematic diagram of the structure of a magnetic protective sleeve according to an exemplary embodiment. Figure 2 This is a cross-sectional schematic diagram of a magnetic protective sleeve according to an exemplary embodiment. For example... Figure 1 and Figure 2As shown, the magnetic protective sleeve includes a magnetic component 1 and a metal component 2. The magnetic component 1 and the metal component 2 are stacked and spaced apart, with the metal component 2 positioned relative to the magnetic component 1 closer to the inner side of the magnetic protective sleeve. This inner side of the magnetic protective sleeve can be understood as facing the outer surface of the electronic device after assembly. With this configuration, after assembly, the metal component 2 is located between the electronic device and the magnetic component 1, allowing it to be positioned relatively close to the near-field antenna radiator of the electronic device. When the near-field antenna radiator is excited by a current, the metal component 2 can couple with the near-field antenna radiator, improving its radiation performance and balancing near-field communication performance with the magnetic attraction effect of the magnetic protective sleeve.

[0035] In some embodiments, still using Figure 1 As shown, the magnetic chuck 1 can be a magnetic ring, such as a loop formed by multiple magnets arranged end-to-end. This magnetic ring can have one or more breaks 11. These breaks 11 help reduce the overlap area between the near-field antenna radiator and the magnetic chuck 1, improving near-field communication performance. For example, depending on the size of the overlap area between the near-field antenna radiator and the magnetic chuck 1, a location with a larger overlap area or a location with better near-field antenna radiator performance can be selected to create the breaks, ensuring good near-field communication performance. The central angle corresponding to the break 11 can be greater than or equal to 10° and less than or equal to 20°. For example, the central angle corresponding to the break 11 can be 15°. This allows for consideration of the radiation performance of the near-field antenna radiator while avoiding significant weakening of the magnetic attraction capability of the magnetic chuck 1.

[0036] In some embodiments, considering that the near-field antenna radiator in an electronic device is typically arranged in a ring or quasi-ring structure, the metal component 2 may include a metal ring, and the metal ring has an antenna slot. Thus, the arrangement of the metal ring helps to increase the coupling area between the near-field antenna radiator and the metal component 2, improving near-field communication performance. Furthermore, the antenna slot ensures that electromagnetic wave signals on the metal component 2 can be transmitted for communication.

[0037] Based on the technical solution disclosed herein, such as Figure 3As shown, this disclosure also provides a device module, which includes an electronic device 100 and the magnetic protective sleeve described in any of the foregoing embodiments. The electronic device is detachably assembled to the magnetic protective sleeve, which enables the magnetic function of the electronic device. The electronic device 100 includes a near-field antenna radiator 3. In the thickness direction of the electronic device 100, the metal part 2 of the magnetic protective sleeve is located between the near-field antenna radiator 3 and the magnetic part 1. This facilitates the coupling between the near-field antenna radiator 3 and the metal part 2, allowing a near-field communication current to be excited on the metal part 2, thereby improving the near-field communication effect.

[0038] Of course, to ensure smooth coupling, the projections of the near-field antenna radiator 3 and the metal part 2 should at least partially overlap, and the distance between the metal part 2 and the near-field antenna radiator 3 can be greater than or equal to 0.5 mm and less than or equal to 1 mm. Setting a minimum distance of 0.5 mm can reduce the design requirements for the thickness of the magnetic protective sleeve and the fitting gap requirements between the magnetic protective sleeve and the electronic device. Setting a maximum distance of 1 mm can ensure the coupling effect between the near-field antenna radiator 3 and the metal part 2.

[0039] Considering that the signal radiation of the near-field antenna radiator 3 is mainly affected by the obstruction of the magnetic accumulator 1, in some embodiments, the overlap between the projection of the near-field antenna radiator 3 and the projection of the magnetic accumulator 1 is less than or equal to 1 mm. For example, as... Figure 4 As shown, the projection of the near-field antenna radiator 3 and the projection of the magnetic accumulator 1 are partially offset, partially tangent, or partially overlapped, with the overlap size being less than or equal to 1 mm. Alternatively, the projection of the near-field antenna radiator 3 and the projection of the magnetic accumulator 1 can be completely offset. The specific design can be customized as needed.

[0040] In some other embodiments, such as Figure 4 As shown, the magnetic accumulator 1 is provided with one or more breaks 11, and at least 2 / 3 of the width of the near-field antenna radiator 3 is smaller than that of the magnetic accumulator 1, which can be exposed through the breaks 11. In this way, by setting the breaks, the break 11 is designed in the area where the magnetic accumulator 1 and the near-field antenna radiator 3 have a large overlapping area, that is, the area that has a great impact on the performance of the near-field antenna radiator 3. This increases the exposed area of ​​the near-field antenna radiator 3 and reduces the overlapping area between the near-field antenna radiator 3 and the magnetic accumulator 1, thereby improving the near-field communication performance of the near-field antenna radiator 3.

[0041] In the above embodiments, such as Figure 5As shown, the electronic device also includes a substrate 4 and a high-permeability element 5. A near-field antenna radiator 3 is disposed on one side of the substrate 4, and the high-permeability element 5 is disposed on the opposite side of the substrate 4. The high-permeability element 5 and the near-field antenna radiator 3 are stacked and spaced apart, and the projection of the high-permeability element 5 covers and extends beyond the projection of the near-field antenna radiator 3. Utilizing the high magnetic response capability of the high-permeability element 5 to magnetic fields, the magnetic flux is increased, thereby improving near-field communication performance. For example, the projection extension distance of the high-permeability element 5 can be greater than or equal to 2 mm. This disclosure does not limit the scope of the near-field antenna radiator 3's projection to the projection of the high-permeability element 5, which may or may not be limited to a specific projection area of ​​the near-field antenna radiator 3.

[0042] In some embodiments, such as Figure 5 As shown, the near-field antenna radiator 3 can include a corner segment 23 and a straight segment 24. The projection distance of the high permeability element 5 corresponding to the corner segment 23 is greater than that of the high permeability element 5 corresponding to the straight segment 24. In other words, the high permeability element 5 is wider at the corner segment 23 and relatively narrower at the straight segment 24. This utilizes the characteristic that the corner segment 23 can concentrate a stronger magnetic field, thus having a greater impact on near-field communication performance. Setting a relatively wider high permeability element 5 can further enhance the communication performance of the corner segment 23, resulting in a more significant improvement in near-field communication performance. The straight segment 24 does not refer to a strictly straight line; it can certainly have a certain polygonal shape. The straight segment 24 can mainly include areas where the current does not change direction, while the corner segment 23 can mainly include areas where the current does change direction.

[0043] In some embodiments, the near-field antenna radiator 3 may include a corner segment 23 and a straight segment 24, and the width of the corner segment 23 is greater than the width of the straight segment 24. This widening of the corner segment 23, which is highly sensitive to near-field performance, increases the coupling area and improves radiation efficiency. In addition, the increased width of the corner segment 23 helps to reduce impedance and improve near-field communication performance.
