Description

Technical Field

[0001] The utility model relates to the technical field of charging equipment, and in particular to a magnetic base structure for wireless power transmission. Background Art

[0002] A wireless charging socket is a new type of power socket that integrates wireless charging technology and the functions of a traditional socket. The wireless charging socket uses the principle of electromagnetic induction and a built-in wireless charging module to convert electrical energy into a magnetic field, and then convert the magnetic field into electrical energy to charge the devices placed on the socket.

[0003] Specifically, electromagnetic induction wireless charging uses the electromagnetic induction principle of electricity generating magnetism and magnetism generating electricity, that is, the mutual conversion of "electricity" and "magnetism". This principle is similar to that of a transformer. By setting coils at the transmitting end and the receiving end, the transmitting end coil sends electromagnetic signals outward under the action of electricity, and the receiving end coil receives the electromagnetic signals and converts them into current, thereby achieving the purpose of wireless charging.

[0004] Patent publication number CN105071170A discloses a wireless charging socket. By designing the socket into a structure including a support plate portion and a wall portion, and making the support plate portion and the wall portion rotatably connected, the thickness of the socket installed in the wall portion will not be increased, which is convenient for installation. When charging, small electronic devices such as devices can be placed on the support plate portion without the need to use additional tools to support the electronic devices, making charging more convenient. When not charging, the support plate portion can be folded and snapped onto the wall portion, so that the socket occupies less space.

[0005] However, the above device still has some shortcomings in actual use. The most obvious one is that the device is not stable enough when placed on the pallet, which makes it easy for the device to fall and cause damage. If the device slides, the receiving coil inside the device will not be able to effectively align with the transmitting coil, affecting the stability and safety of charging transmission and reducing charging efficiency.

[0006] At the same time, the socket does not have a charging adapter function, and the device must be placed on the tray to charge, which is not very practical. Utility Model Content

For example, if the device in the drawings is turned over, a component described as "below" or "beneath" another component or feature would then be oriented "above" the other component or feature. Thus, the exemplary term "below" can encompass both "above" and "below" orientations. Furthermore, the device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein interpreted accordingly.

[0028] like Figure 1-3 As shown, a magnetic base structure for wireless power transmission disclosed in the present invention includes a power transmission base 1, a pressure cover 2, a power receiver 3 and a wire box 4;

[0029] The transmitting end coil is fixedly installed on the inner wall of the front side of the power transmission base 1, and a U-shaped slot 11 is provided on the front surface of the power transmission base 1 at the outer position of the transmitting end coil. The cross-sectional dimensions of the pressure cover 2 correspond to the cross-sectional dimensions of the U-shaped slot 11. The pressure cover 2 is movably inserted into the power transmission base 1 through the U-shaped slot 11. The upper part of the pressure cover 2 is open, and an accommodating cavity 21 is formed between the outside of the pressure cover 2 and the front surface of the power transmission base 1. A slide slot 23 is provided at the front position of the bottom of the pressure cover 2. The power receiver 3 is inserted into the slide slot 23, and the receiving end coil is installed in the power receiver 3. The wire box 4 is fixedly installed on the front surface of the pressure cover 2, and the wire box 4 is used to install the charging adapter 5.

[0030] The above-mentioned accommodating cavity 21 is used to place the device. When the device is placed in the accommodating cavity 21, the transmitting end coil of the power transmission base 1 sends electromagnetic signals outward under the action of electricity, and the receiving end coil of the device receives the electromagnetic signals and converts them into current, thereby realizing charging of the device.

[0031] Furthermore, in order to improve the stability of the device during charging, in this embodiment, ribs 22 are fixedly installed on both side walls of the pressure cover 2 located inside the power transmission base 1, and multiple springs 24 are fixedly installed between the ribs 22 and the front inner wall of the power transmission base 1. The elastic force of the springs 24 can move the pressure cover 2 toward the position of the power transmission base 1, thereby stably pressing the device in the accommodating cavity 21 to prevent the device from moving.

[0032] Furthermore, in order to facilitate the lifting and lowering of the power receiver 3, as shown in FIG. Figure 4As shown, in this embodiment, the power receiver 3 is a plate-shaped structure, a magnetic plate 32 is fixedly mounted on the front side of the lower end of the power receiver 3, a plurality of magnets 33 are fixedly mounted on the upper part of the magnetic plate 32, and a limit plate 31 is fixedly mounted on one side of the upper end of the power receiver 3, which can effectively prevent the power receiver 3 from being separated from the slide slot 23;

[0033] The above-mentioned power transmission base 1 adopts a metal material structure, which can be a stainless steel or iron structure. When the power receiver 3 is pushed into the power transmission base 1, the receiving end coil of the power receiver 3 can be close to the transmitting end coil of the power transmission base 1. The transmitting end coil of the power transmission base 1 sends electromagnetic signals outward under the action of electricity. The receiving end coil of the power receiver 3 receives the electromagnetic signal and converts the electromagnetic signal into current, and then charges the external device through the charging adapter 5, so that the charging operation can be performed without placing the device in the accommodating cavity 21.

[0034] like Figure 5 As shown, in this embodiment, the charging adapter 5 includes a cable 51 and multiple charging heads 52, the multiple charging heads 52 are electrically connected to the cable 51, and the other end of the cable 51 is electrically connected to the receiving end coil inside the power receiver 3.

[0035] In another embodiment, the above-mentioned multiple charging heads 52 can be charging heads 52 with different types of interfaces, such as any combination of USB-A, USB-B, USB-C, Type-c, and Lightning interfaces.

[0036] Furthermore, in order to facilitate the storage of the cable 51 , in this embodiment, a rotating shaft 41 is rotatably installed in the wire box 4 , and the cable 51 is wound around the surface of the rotating shaft 41 .

[0037] In this embodiment, the power transmission base 1 is fixedly installed with hanging ears 12 on both sides. The hanging ears 12 are provided with threaded holes. The power transmission base 1 can be installed in the hidden box on the wall through the screws on the hanging ears 12, so that the power transmission base 1 is stably embedded in the wall.

[0038] Furthermore, in order to facilitate the user to slide the power receiver 3 off the power transmission base 1 , in this embodiment, two ends of the magnetic attraction plate 32 protrude from two sides of the power receiver 3 respectively.

[0039] The specific operation steps are as follows: the accommodating cavity 21 is used to place the device. The device is placed in the accommodating cavity 21. The transmitting end coil of the power transmission base 1 sends an electromagnetic signal outward under the action of electricity. The receiving end coil of the device receives the electromagnetic signal and converts the electromagnetic signal into current, thereby charging the device. The elastic force of the spring 24 can move the pressure cover 2 toward the position of the power transmission base 1, thereby stably pressing the device in the accommodating cavity 21 to prevent the device from moving.

[0040] When the power receiver 3 is pushed into the power transmission base 1, the receiving end coil of the power receiver 3 can be close to the transmitting end coil of the power transmission base 1. The transmitting end coil of the power transmission base 1 sends electromagnetic signals outward under the action of electricity. The receiving end coil of the power receiver 3 receives the electromagnetic signals and converts the electromagnetic signals into current, and then charges the external device through the charging adapter 5, so that the charging operation can be performed without placing the device in the accommodating cavity 21.
