Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coil structures, and in particular to a novel wireless power supply flat coil structure. Background Art
[0002] Wireless power technology is playing an increasingly important role in modern electronics and energy transmission. As a key component in wireless power systems, the performance of planar coils directly impacts the efficiency and reliability of the entire system. With the increasing popularity and intelligence of portable electronic devices, the demand for wireless charging is growing. Traditional wired charging methods suffer from issues like cable entanglement, interface wear, and inconvenience. Wireless power technology offers users a more convenient and efficient charging experience, hence the need for this structure.
[0003] In the existing wireless power supply flat coil structure, the coil is usually fixed and installed using sealing tape or hot melt adhesive during the packaging process. In actual use, this packaging method is relatively cumbersome to operate because a hot air gun is needed to melt the adhesive before fixing it. When a new coil needs to be replaced, a hot air gun is needed to melt the hot melt adhesive before disassembly, which makes it difficult to operate. The hot air gun can easily damage the protective rubber on the outside of the coil. Utility Model Content
[0004] In order to make up for the above shortcomings, the utility model provides a novel wireless power supply flat coil structure, which aims to improve the problem that the flat coil is difficult to disassemble and install during packaging.
[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a novel wireless power supply flat coil structure, comprising a base plate, an upper surface of the base plate fixedly connected to an electromagnet 1, an upper surface of the base plate provided with a mounting assembly, an outer wall of the electromagnet 1 provided with a connecting assembly, the mounting assembly comprising a base 1, a lower surface of the base fixedly connected to the upper surface of the base plate, a card slot provided inside the base 1, a base 2 slidably connected to the inner wall of the base 1, a button slidably connected to the inner wall of the base 2, one end of the button fixedly connected to a pressure rod, one end of the pressure rod fixedly connected to a pin, the outer wall of the pin slidably connected to the inner wall of the base 2, a spring provided at one end of the button, a steel ball provided inside the base 2, and the outer wall of the steel ball slidably connected to the inner wall of the base 1.
[0006] Furthermore, the connecting assembly includes a connecting block, and one side of the outer wall of the connecting block is fixedly connected to an outer wall of the electromagnet.
[0007] Furthermore, a coil 1 is slidably connected inside the electromagnet 1, one end of the coil 1 is electrically connected to a relay, and an output end of the relay is electrically connected to an output port.
[0008] Furthermore, a heat sink is fixedly connected to the upper surface of the base plate, an electromagnet 2 is fixedly connected to the upper surface of the heat sink, a coil 2 is slidably connected inside the electromagnet 2, a receiver is fixedly connected to the upper surface of the base plate, and the receiver is electrically connected to coil 1.
[0009] Furthermore, the outer wall of the pressure rod is slidably connected to the second inner wall of the base.
[0010] Furthermore, one end of the spring is fixedly connected to the lower surface of the button, and the other end of the spring is fixedly connected to the inside of the second base.
[0011] Furthermore, the lower surface of the relay is fixedly connected to the upper surface of the base plate.
[0012] Furthermore, the lower surface of the output port is fixedly connected to the upper surface of the base plate.
[0013] The utility model has the following beneficial effects:
[0014] The spring is then pulled out to separate the base from the first base, and the first and second bases are then released, allowing the spring to push the latch upwards and push the steel ball away from the second base, which opens the second base and engages the internal slot of the first base, thereby connecting the second base to the first base.
[0015] 2. In the present invention, a flat coil design is adopted. Compared with the traditional cylindrical coil, the flat coil is easier to integrate into electronic equipment and takes up less space. A distributed magnetic core structure is adopted to divide the magnetic core into multiple small blocks, which are evenly distributed around the coil, reducing the eddy current loss and heat generation of the magnetic core. At the same time, a heat sink is set on the bottom plate to dissipate the heat generated by coils one and two, thereby achieving the heat dissipation effect and avoiding the coils from not being able to work normally due to high temperature.

The other end of the spring 7 is fixedly connected to the inside of the base 2 4. The quick connection between the base 1 3 and the base 2 4 realizes the quick installation of the coil 12.
[0023] Reference Figure 1 , electromagnet 11 is slidably connected to coil 12 inside, coil 12 is used to introduce the generated electric energy into relay 17, one end of coil 12 is electrically connected to relay 17, relay is used to receive the electric energy generated by coil 12, the output end of relay 17 is electrically connected to output port 18, output port 18 is used to output electric energy, the upper surface of base plate 1 is fixedly connected to heat sink 13, heat sink 13 is used to dissipate heat for coil 12 and coil 2 14, the upper surface of heat sink 13 is fixedly connected to electromagnet 2 16, electromagnet 2 16 is used to generate induced electromotive force, electromagnet 2 16 is slidably connected to coil 2 14 inside, the upper surface of base plate 1 is fixedly connected to receiver 15, receiver 15 is used to receive the alternating magnetic field at the output end, receiver 15 is electrically connected to coil 12, the lower surface of relay 17 is fixedly connected to the upper surface of base plate 1, and the lower surface of output port 18 is fixedly connected to the upper surface of base plate 1.
[0024] Working principle: When the device is needed, the power supply device transmitter first drives the flat coil through high-frequency alternating current to generate an alternating magnetic field, and then receives the electromagnetic field through the receiver 15, so that the coil 12 and the coil 2 14 generate an induced electromotive force through the electromagnet 11, and the magnetic field energy is converted into electrical energy. The generated electrical energy is output from the output port 18 through the relay 17 to power the electronic equipment. By arranging a heat sink 13 above the bottom plate 1, the heat generated by the coil 12 and the coil 2 14 during operation is discharged to avoid the coil 12 and the heat sink 13 from malfunctioning due to high temperature.

In this way, the connection between the base 2 4 and the base 1 3 is achieved, so that the coil 12 can be quickly installed, and the installation efficiency is higher than that of the existing technology. Similarly, when disassembly is required, the button 5 is pressed, so that the button 5 drives the latch 8 to move downward. When the latch 8 slides to the bottom of the steel ball 10, the steel ball 10 shrinks toward the inside of the base 2 4, so that it is separated from the slot 9, and then the base 2 4 can be pulled out from the base 1 3. In this way, the base 2 4 and the base 1 3 are separated, so that the coil 12 can be quickly disassembled and replaced.
