After the electronic device 200 is installed in the installation cavity 113, the electronic device 200 and the protective electronic device case 100 are relatively fixed. At this time, the first positioning assembly 120 on the main body 110 and the second charging assembly 320 on the charger are connected, so that the electronic device protection case 100 and the charging device 300 are kept relatively fixed. Accordingly, the electronic device 200 and the charging device 300 are fixed relative to each other.

And, the disposed positions of the first and

second positioning assemblies

120 and 320 are such that the first and second charging coils 210 and 310 are maintained coaxially disposed to optimize the charging power.

In one example, as shown in fig. 2-2, a first charging coil 210 is provided in an electronic device 200, along with a third positioning assembly 220. A second charging coil 310, and a second positioning assembly 320 are provided in the charging device 300.

After the electronic device 200 is installed in the installation cavity 113, the electronic device 200 and the protective electronic device case 100 are relatively fixed.

The first positioning assembly 120 on the main body 110 and the second charging assembly 320 on the charger are connected, so that the electronic device protection shell 100 and the charging device 300 are kept relatively fixed. Accordingly, the electronic device 200 and the charging device 300 are fixed relative to each other.

And, the arrangement positions of the first positioning assembly 120, the second positioning assembly 320 and the third positioning assembly 220 are such that the first charging coil 210 and the second charging coil 310 are maintained coaxially arranged to optimize the charging power.

Fig. 3-1, 3-2, and 3-3 are schematic structural views of an electronic device protective case according to various exemplary embodiments. As shown in fig. 3-1, 3-2, and 3-3, the first positioning component 120 includes: a first magnetic member 121 and a second magnetic member 122.

The first magnetic member 121 is disposed around a predetermined region 111x on the bottom surface of the mounting cavity. Optionally, the preset area 111x corresponds to a second charging coil arrangement on the charging device. Accordingly, when the electronic device protection case 100 is connected to an electronic device, the first magnetic member 121 is disposed corresponding to an area surrounding the second charging coil.

At this time, the first magnetic member 121 and the second magnetic member 122 form a ring shape surrounding the predetermined region 111x, and the second magnetic member 122 is disposed to protrude from the first magnetic member 121 in a radial direction of the ring shape.

In this way, the first magnetic member 121 and the second magnetic member 122 jointly play a magnetic attraction role, so as to achieve stable connection with the second positioning component on the charging device and/or the third positioning component on the electronic device. Moreover, the second magnetic member 122 protrudes from the first magnetic member 121 to the outside of the preset region 111x, so that the magnetic action range on the electronic device protection shell 100 is expanded, the electronic device protection shell 100 is stably connected with the charging device, and the second charging coil in the charging device and the first charging coil in the electronic device are coaxially arranged.

With respect to the implementation of the second magnetic member 122, the disclosed embodiments provide a number of alternative examples. Fig. 4-1, 4-2, and 4-3 are schematic structural views of a second magnetic member according to various exemplary embodiments.

As shown in fig. 4-1 to 4-3, the second magnetic member 122 includes: a first portion 1221 and a second portion 1222 extending in different directions. The first portion 1221 is disposed at the notch 121x and extends to the outside of the preset area 111 x. The second portion 1222 is located inside and/or outside the preset region 111 x.

For example, as shown in fig. 4-1, the first portion 1221 of the second magnetic member 122 is disposed at the notch 121x, and the second portion 1222 is disposed outside the predetermined region 111 x.

For example, as shown in fig. 4-2, the first portion 1221 of the second magnetic member 122 is disposed at the notch 121x, and one end of the first portion 1221 protrudes out of the predetermined region 111x to the first magnetic member 121. The other end of the first portion 1221 is connected to the second portion 1222, and the second portion 1222 is disposed inside the preset region 111 x.

For example, as shown in fig. 4-3, the first portion 1221 of the second magnetic member 122 is disposed at the notch 121x, and one end of the first portion 1221 protrudes out of the predetermined region 111x of the first magnetic member 121. The second magnetic member 122 includes two second portions 1222, one of the second portions 1222 is located outside the predetermined region 111x, and the other second portion 1222 is located inside the predetermined region 111 x.

When the electronic device is connected to the electronic device protection case 100, the contact 140 is electrically connected to a contact on a side of the electronic device, so that the magnetic force detecting element 130 is electrically connected to the electronic device.

Since the first positioning component 120 on the electronic device protection casing 100 is a magnetic component, the magnetic field strength of the electronic device during charging is increased. Moreover, wireless charging is realized based on magnetoelectric conversion, so that if the magnetic field intensity is too large in the wireless charging process, the wireless charging is interrupted to protect the charging, and the charging process is interrupted.

Under such a situation, adopt magnetic detection subassembly 130 to detect the magnetic field intensity between electronic equipment and the charging equipment, respond to magnetic field intensity and be greater than the preset threshold value, reduce the power that wireless charges, and then reduce the magnetic field intensity between first charging coil and the second charging coil to avoid interrupting the charging.

In addition, the magnetic part is heated up due to the fact that the magnetic field intensity is too large, the magnetic field intensity is monitored through the magnetic detection assembly 130, the fact that the temperature of the magnetic part (the first positioning assembly 120, the second positioning assembly and the third positioning assembly) is too high is avoided, and user experience is optimized.
