Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, specifically relating to a protective case for an electronic device and the electronic device itself. Background Technology

[0002] In related technologies, protective cases with integrated brackets are generally not suitable for electronic devices that do not have wireless charging capabilities. This is because the brackets of protective cases are usually made of metal to improve support and lifespan.

[0003] The magnetic field generated by the wireless charging of electronic devices can create eddy currents on the surface of the charging stand, generating heat. This can cause the stand to heat up quickly, potentially burning the back of the electronic device or burning the user. Summary of the Invention

[0004] This application aims to provide a protective case and an electronic device that can solve one of the technical problems in the related art where protective cases with brackets cannot be used for wireless charging electronic devices.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] In a first aspect, this application provides a protective case for an electronic device, comprising:

[0007] main body;

[0008] The bracket is installed on the main body;

[0009] The first magnetic conductive element is disposed on the first side of the bracket;

[0010] The second magnetic conductor is located on the second side of the bracket.

[0011] Secondly, this application provides an electronic device, comprising:

[0012] The protective case for the electronic device provided in the first aspect embodiment.

[0013] In the embodiments of this application, the protective shell of the electronic device includes a main body, a bracket, a first magnetic conductive element and a second magnetic conductive element. The bracket has a first side and a second side, which are opposite to each other. The first magnetic conductive element is disposed on the first side of the bracket, and the second magnetic conductive element is disposed on the second side of the bracket. The first magnetic conductive element can face the receiving coil of the electronic device, and the second magnetic conductive element can face the transmitting coil of the charger.

[0014] The protective case for the electronic device can be the back cover or a protective sleeve. When the electronic device is wirelessly charged, the first magnetic conductor faces the receiving coil of the electronic device, and the second magnetic conductor faces the transmitting coil of the charger. As a result, the magnetic field lines generated during charging will preferentially pass through the path with higher magnetic permeability. In other words, the first and second magnetic conductors reduce the number of magnetic field lines passing through the bracket, thereby reducing the attempt of eddy currents on the bracket, reducing the possibility of the bracket overheating, and ensuring the wireless charging effect of the electronic device.

[0035] The following is combined Figures 1 to 12 This application describes a protective case 100 and an electronic device 200 according to embodiments of the present application.

[0036] like Figure 1 , Figure 3 , Figure 5 and Figure 7 As shown, this application provides a protective case 100 for an electronic device, including: a main body 110; a bracket 120 disposed on the main body 110; a first magnetic conductive element 130 disposed on a first side of the bracket 120; and a second magnetic conductive element 140 disposed on a second side of the bracket 120. Specifically, the bracket 120 is made of metal.

[0037] In the embodiments of this application, the protective case 100 of the electronic device includes a main body 110, a bracket 120, a first magnetic conductive element 130 and a second magnetic conductive element 140. The bracket 120 has a first side and a second side, which are opposite to each other. The first magnetic conductive element 130 is disposed on the first side of the bracket 120, and the second magnetic conductive element 140 is disposed on the second side of the bracket 120. The first magnetic conductive element 130 can face the receiving coil 210 of the electronic device 200, and the second magnetic conductive element 140 can face the transmitting coil 310 of the charger 300.

[0038] The protective case 100 of the electronic device can be the back cover of the electronic device 200. After it is installed on the electronic device 200, when the electronic device 200 is wirelessly charged, the first magnetic conductor 130 faces the receiving coil 210 of the electronic device 200, and the second magnetic conductor 140 faces the transmitting coil 310 of the charger 300. As a result, the magnetic field lines generated during charging will preferentially pass through the path with higher magnetic permeability. That is, the number of magnetic field lines passing through the bracket 120 is reduced by the first magnetic conductor 130 and the second magnetic conductor 140, thereby reducing the generation of eddy currents on the bracket 120, reducing the possibility of the bracket 120 overheating, and ensuring the wireless charging effect of the electronic device 200. Moreover, there is no need to cut or offset the receiving coil 210 of the electronic device 200 or the transmitting coil 310 of the charger 300, which is highly adaptable.

[0039] Or, such as Figure 3 and Figure 5As shown, the protective case 100 of the electronic device can be a protective sleeve for the electronic device 200. One side of its main body 110 includes a connecting portion 112, which is disposed on one side of the main body 110 for connection with the electronic device 200. A first side of the bracket 120 is close to the connecting portion 112, and a second side of the bracket 120 is away from the connecting portion 112. After being installed on the electronic device 200, when the electronic device 200 uses wireless charging, the first magnetic conductor 130 faces the receiving coil 210 of the electronic device 200, and the second magnetic conductor 140 faces the charger 3. The transmitting coil 310 of the 00, and the magnetic field lines generated during charging, will preferentially pass through the path with higher magnetic permeability. That is, the number of magnetic field lines passing through the bracket 120 is reduced by the first magnetic conductor 130 and the second magnetic conductor 140, thereby reducing the generation of eddy currents on the bracket 120 and reducing the possibility of the bracket 120 overheating. This makes the protective case of the electronic device 200 suitable for wireless charging scenarios. Moreover, there is no need to cut or offset the receiving coil 210 on the electronic device 200 or the transmitting coil 310 of the charger 300, which is highly adaptable.

[0040] like Figure 2 As shown, when the protective case 100 of the electronic device is installed on the electronic device 200, it directly corresponds to the position of the receiving coil 210 of the electronic device 200, and the bracket 120 only partially blocks the receiving coil 210.

[0041] like Figure 4 As shown, the first magnetic guide 130 is located between the bracket 120 and the electronic device 200 and the receiving coil 210, and the second magnetic guide 140 is located between the bracket 120 and the transmitting coil 310 of the charger 300. The first magnetic guide 130 guides magnetic field lines, reducing the number of magnetic field lines passing through the bracket 120, thereby reducing eddy currents generated on the bracket 120 and lowering the temperature rise of the bracket 120 during charging. Figure 4 The arrows in the diagram represent magnetic field lines.

[0042] Furthermore, the first magnetic conductive element 130 covers the entire first side of the bracket 120, meaning that the bracket 120 is projected onto the first magnetic conductive element 130 and is entirely within the first magnetic conductive element 130. The second magnetic conductive element 140 covers the entire second side of the bracket 120, meaning that the bracket 120 is projected onto the second magnetic conductive element 140 and is entirely within the second magnetic conductive element 140. This allows the first magnetic conductive element 130 and the second magnetic conductive element 140 to completely isolate the bracket 120, further reducing the generation of eddy currents on the bracket 120 and reducing the possibility of the bracket 120 overheating. As a result, the protective case 100 for electronic devices is suitable for wireless charging scenarios.

[0043] like Figure 3 , Figure 5 and Figure 7As shown, in one possible implementation, the bracket 120, the first magnetic conductor 130, and the second magnetic conductor 140 are embedded in the main body 110.

[0044] Specifically, the main body 110 has a mounting groove, and the first magnetic conductor 130 and the second magnetic conductor 140 are embedded in the main body 110 and located in the mounting groove, thereby reducing the thickness of the protective shell 100 of the electronic device and improving the wireless charging effect.

[0045] like Figure 5 and Figure 6 As shown, as one possible implementation, it further includes: a third magnetic conductor 150, connected between the first magnetic conductor 130 and the second magnetic conductor 140, and located on the side of the bracket 120.

[0046] Specifically, the protective case 100 of the electronic device also includes a third magnetic conductive element 150, which is located on the side of the bracket 120. The third magnetic conductive element 150 is connected to the first magnetic conductive element 130 and the second magnetic conductive element 140. The third magnetic conductive element 150 can guide at least a portion of the magnetic field lines to flow between the first magnetic conductive element 130 and the second magnetic conductive element 140, thereby reducing magnetic leakage, reducing eddy current losses in the bracket 120, and further reducing the temperature of the bracket 120.

[0047] like Figure 6 As shown, the cross-sections of the first magnetic conductive element 130, the second magnetic conductive element 140, and the third magnetic conductive element 150 form a "C" shape, semi-enclosing the bracket 120. Furthermore, the third magnetic conductive element 150 alters the magnetic field line path, guiding the magnetic field lines entering through the second magnetic conductive element 140 into the first magnetic conductive element 130, thereby reducing magnetic leakage, increasing charging power, and lowering eddy current losses in the bracket 120. Figure 6 The arrows in the diagram represent magnetic field lines.

[0048] like Figure 7 and Figure 8 As shown, in one possible implementation, the third magnetic conductor 150 has a ring structure, and the first magnetic conductor 130, the second magnetic conductor 140 and the third magnetic conductor 150 form a receiving cavity, with the support 120 located inside the receiving cavity.

[0049] Specifically, the third magnetic conductive element 150 has a ring-shaped structure that surrounds the support 120. The first magnetic conductive element 130, the second magnetic conductive element 140, and the third magnetic conductive element 150 are combined to form a receiving cavity. The support 120 is placed in the receiving cavity, and the entire surface of the support 120 is covered by the first magnetic conductive element 130, the second magnetic conductive element 140, and the third magnetic conductive element 150. In other words, the first magnetic conductive element 130, the second magnetic conductive element 140, and the third magnetic conductive element 150 completely surround the support 120, minimizing the formation of eddy currents on the support 120.

[0050] like Figure 8 As shown, the first magnetic conductor 130 is located between the bracket 120 and the receiving coil 210, the second magnetic conductor 140 is located between the bracket 120 and the transmitting coil 310, and the third magnetic conductor 150 is disposed on the side of the bracket 120 and connects the first magnetic conductor 130 and the second magnetic conductor 140. The third magnetic conductor 150 alters the magnetic field path, guiding the magnetic field lines entering through the second magnetic conductor 140 into the first magnetic conductor 130, thereby reducing magnetic leakage, increasing charging power, and reducing eddy current losses in the bracket 120. Figure 8 The arrows in the diagram represent magnetic field lines.

[0051] That is, the first magnetic conductor 130 guides the magnetic field lines, reducing the number of magnetic field lines passing through the bracket 120, thereby reducing the eddy currents generated on the bracket 120 and reducing the temperature rise of the bracket 120 during charging.

[0052] As one possible implementation, the first magnetic conductive element 130, the second magnetic conductive element 140, and the third magnetic conductive element 150 are an integral structure.

[0053] Specifically, the first magnetic conductive element 130, the second magnetic conductive element 140, and the third magnetic conductive element 150 are integrated into one piece, which improves the connection strength between the first magnetic conductive element 130, the second magnetic conductive element 140, and the third magnetic conductive element 150, reduces the possibility of the first magnetic conductive element 130, the second magnetic conductive element 140, and the third magnetic conductive element 150 falling off, and improves the reliability of the magnetic conduction of the first magnetic conductive element 130, the second magnetic conductive element 140, and the third magnetic conductive element 150.

[0054] like Figure 10 , Figure 11 and Figure 12 As shown, in one possible implementation, the bracket 120 is provided with a plurality of empty portions 122, each empty portion 122 including a groove or a through hole. The groove is recessed from the first side of the bracket 120 toward the second side of the bracket 120, or from the second side of the bracket 120 toward the first side of the bracket 120, and the through hole connects the first side of the bracket 120 and the second side of the bracket 120.

[0055] Specifically, the bracket 120 is provided with a plurality of empty portions 122, which can be grooves or through holes.

[0056] The groove is recessed from the first side of the bracket 120 toward the second side of the bracket 120, or from the second side of the bracket 120 toward the first side of the bracket 120, thereby cutting off the eddy current circuit by utilizing the vacancy 122, reducing the temperature rise of the bracket 120 during charging, and improving the wireless charging effect of the electronic device 200 and the charger 300, and increasing the charging power of the electronic device 200.

[0057] The through-hole conductive bracket 120 has openings on both the first and second sides of the bracket 120. This allows the eddy current circuit to be cut off by the vacancy 122, reducing the temperature rise of the bracket 120 during charging. Furthermore, it can improve the wireless charging effect of the electronic device 200 and the charger 300, and increase the charging power of the electronic device 200.

[0058] Furthermore, the first magnetic conductive element 130 and the second magnetic conductive element 140 enclose the rest of the bracket 120, thereby reducing the influence of the magnetic field on the bracket 120.

[0059] Among them, such as Figure 9 As shown, without the missing portion 122, a complete vortex will be formed on the support 120. Figure 9 The arrows in the diagram represent eddies. And as... Figure 10 , Figure 11 and Figure 12 As shown, the eddy current is interrupted by the vacancy 122, reducing the temperature rise of the bracket 120 during charging. Figure 10 , Figure 11 and Figure 12 The arrows in the diagram represent eddies.

[0060] like Figure 10 , Figure 11 and Figure 12 As shown, in one possible implementation, the multiple vacant portions 122 are all strip-shaped structures, and the multiple vacant portions 122 extend in the same direction.

[0061] Specifically, the multiple vacant portions 122 all adopt a strip structure, and the multiple vacant portions 122 extend in the same direction, thereby improving the ability of the vacant portions 122 to cut off the eddy current circuit and further reducing the temperature rise of the bracket 120 during charging.

[0062] like Figure 10 As shown, the extension direction of the multiple vacant portions 122 can be transverse, and the transversely truncated vortex, such as... Figure 11 As shown, the extension direction of the multiple vacant portions 122 can be oblique, obliquely truncating the vortex, such as... Figure 12 As shown, the extension direction of the multiple vacant parts 122 can be longitudinal, which is a longitudinal truncation vortex.

[0063] The multiple vacant sections 122 can be a single-row or multi-row array structure.

[0064] like Figure 10 , Figure 11 and Figure 12 As shown, in one possible implementation, the length of the vacancy 122 is greater than half the length of the bracket 120 in the extending direction of the vacancy 122.

[0065] Specifically, in the extension direction of the vacancy 122, the length of the vacancy 122 is greater than half of the support 120, thereby ensuring that the vacancy 122 has sufficient length to ensure the effectiveness of the vacancy 122 in cutting off the eddy current circuit, so as to reduce the temperature rise of the support 120 during charging.

[0066] In one possible implementation, the first magnetic conductive element 130 or the second magnetic conductive element 140 covers the groove; or the first magnetic conductive element 130 and the second magnetic conductive element 140 cover the through hole.

[0067] Specifically, when the empty portion 122 is a groove, the first magnetic conductive element 130 or the second magnetic conductive element 140 covers the opening of the groove, reducing the exposed area of ​​the bracket 120, reducing the bracket 120 from directly facing the receiving coil 210 and the transmitting coil 310 due to edge breakage of the first magnetic conductive element 130 or the second magnetic conductive element 140, and improving the reliability of the first magnetic conductive element 130 and the second magnetic conductive element 140 covering the bracket 120.

[0068] When the vacancy 122 is a through hole, the first magnetic conductive element 130 and the second magnetic conductive element 140 cover the opening of the through hole, reducing the exposed area of ​​the bracket 120, reducing the bracket 120 from being directly in front of the receiving coil 210 and the transmitting coil 310 due to edge breakage of the first magnetic conductive element 130 and the second magnetic conductive element 140, and improving the reliability of the first magnetic conductive element 130 and the second magnetic conductive element 140 covering the bracket 120.

[0069] In one possible implementation, the bracket 120 and the main body 110 are rotatably connected.

[0070] Specifically, the bracket 120 and the main body 110 are connected by a pivot, so the bracket 120 has two states: supported and retracted. This makes it convenient for users to take the electronic device 200 out through the protective case 100 of the electronic device, and also makes it convenient for the bracket 120 to support the electronic device 200.

[0071] The protective case 100 for electronic devices can be used with electronic devices 200, including mobile phones, tablets, and wearable devices.

[0072] This application provides an electronic device 200, including a protective case 100 for the electronic device as provided in the first aspect embodiment.

[0073] The electronic device 200 provided in this application includes the protective case 100 of the electronic device as provided in the first aspect embodiment, and therefore has all the beneficial effects of the protective case 100 of the electronic device as provided in the first aspect embodiment, which will not be described in detail here.

[0074] Electronic devices can be mobile phones, tablets, and wearable devices, etc.

[0075] Specifically, the electronic device 200 also includes a frame, on which the protective case 100 of the electronic device is mounted.
