Detailed Description
The invention is further illustrated, but is not limited, by the following examples.
Referring to fig. 1 to 4, a closed wireless charging device for an automobile based on resonant coupling wireless charging according to an embodiment of the present invention includes a lifting charging pile 1 and a charging receiving cavity 2, wherein the charging receiving cavity 2 is disposed on an automobile chassis to form a cavity structure recessed into the automobile, and an opening of the charging receiving cavity 2 is disposed downward, i.e. the opening faces the ground. In this embodiment, the charging receiving cavity 2 is made of an aluminum alloy hollow shell 201 into a rectangular cavity structure, and a receiving antenna 3 is respectively disposed on the top surface and four side walls of the rectangular cavity, that is to say, five receiving antennas 3 are used for receiving electric energy in a wireless manner, and the receiving antennas 3 are attached to the cavity wall of the charging receiving cavity 2. Correspondingly, the lifting charging pile 1 driven by the lifting mechanism 4 is arranged on the ground, and the specific lifting mechanism 4 can adopt a hydraulic ejector rod mechanism, and a piston rod of the hydraulic ejector rod mechanism is arranged upwards. The lifting charging pile 1 is connected to the piston rod, and the lifting charging pile 1 has the function of carrying the transmitting antenna 5 to extend into the charging receiving cavity 2, so that the transmitting antenna 5 corresponds to the receiving antenna 3, and electric energy is wirelessly transmitted to the receiving antenna 3 through the transmitting antenna 5 to charge the vehicle. Therefore, in this embodiment, the outer shape of the lifting charging pile 1 is rectangular, and the transmitting antenna 5 is disposed on the top surface and four sides of the lifting charging pile 1, so that the positions of the transmitting antenna 5 and the receiving antenna 3 are in one-to-one correspondence after the lifting charging pile 1 extends into the charging receiving cavity 2. The transmitting antenna 5 and the receiving antenna 3 are respectively connected with a resonant coupling circuit, so that wireless power transmission can be performed, and the resonant coupling circuit of the receiving antenna can be arranged in the aluminum alloy hollow shell 201 and then is directly connected with an automobile battery. The specific structure of the resonant coupling circuit can adopt a conventional scheme in the prior art, and is not described herein.
Because the invention adopts a plurality of groups of antennas to couple simultaneously, the magnetic fields of the antennas can also have mutual influence. To reduce this interaction, as shown in fig. 5, a charging antenna structure of five receiving antennas 3 and five transmitting antennas 5 is shown, the charging antenna structure includes a non-magnetic conductive substrate 6, a ferrite ring 7 and a coil 8 stacked on top of each other, the non-magnetic conductive substrate 6 may be an aluminum alloy disk, the ferrite ring 7 and the coil 8 and the aluminum alloy disk are coaxially arranged, and the coil 8 of the transmitting antenna is disposed opposite to the coil 8 of the receiving antenna. The ferrite ring 7 is added on the coil 8, the ferrite ring 7 has a magnetism gathering effect, the magnetic leakage phenomenon is obviously reduced, the direct influence of each coil is also reduced, and meanwhile, the influence is continuously weakened by shielding the magnetic field of the aluminum alloy disc behind the ferrite ring 7, so that the purpose that each group of antennas work normally at the same time is achieved, a larger charge amount can be obtained in unit time, and the charge rate is improved. For coil materials, the quasi-static field needs to satisfy:
Namely, -j omega muh is 0, b is magnetic induction intensity, t is time, omega is angular frequency, mu is vacuum magnetic permeability, H is magnetic field intensity, wherein omega is small, so a low frequency circuit is required, and resonant coupling requires a high frequency circuit for achieving higher coupling efficiency, so the skin effect and proximity effect of the coil 8 are considered, and in this embodiment, enameled wire is used as the material of the coil 8. Compared with the prior art, the method adopts the mode that the five receiving antennas 3 and the five transmitting antennas 5 correspond to each other, the side surfaces of the charging piles are fully utilized to enable the plurality of coils to work simultaneously, and the charging rate of the charging piles in unit time is improved. When the charging is carried out by adopting the embodiment, a driver aims at driving the vehicle into a charging position, and when the charging receiving cavity 2 is positioned above the lifting charging pile 1, the lifting charging pile 1 is lifted up by the hydraulic ejector rod mechanism to extend into the charging receiving cavity 2, and then the charging receiving cavity is powered on to carry out wireless charging.
In the resonant coupling circuit, both the coupling distance and the coupling degree (centering degree) of the coil 8 have a certain influence on the wireless charging coil, and in the above-described embodiment, the centering degree of the coil 8 of the transmitting antenna 5 and the receiving antenna 3 tends to be poor when the vehicle is driven to a specified position by the driver. As a further improvement to the above-described embodiment, it is therefore shown in connection with fig. 6 and 7 that the preferred embodiment is to arrange a centering drive mechanism underground, which includes a bottom turntable 9, a radial drive mechanism 10 and a spinning disk 11, wherein the bottom turntable 9 is driven by a motor to rotate in a manner parallel to the ground, and the radial drive mechanism 10 is arranged eccentrically on the bottom turntable 9.

The self-rotating disc 11 is installed on the moving platform 1002 of the servo linear module, the self-rotating disc 11 rotates in a manner parallel to the ground, the self-rotating disc 11 driven to rotate by a motor and a bevel gear is only shown in the figure, and any existing structure can be adopted in specific implementation. The lifting mechanism 4 and the lifting charging pile 1 are mounted on the self-rotating disc 11 such that the longitudinal axis of the lifting charging pile 1 passes through the center of the self-rotating disc 11, and remains coaxial with the rotational axis of the self-rotating disc 11. In addition, 4 groups of infrared sensing devices 12 corresponding to positions are arranged on the periphery of the transmitting antenna 5 on the top surface of the lifting charging pile 1 and the periphery of the receiving antenna on the top surface of the charging receiving cavity 2, so that the lifting charging pile 1 and the charging receiving cavity 2 can be aligned conveniently. the working process of the driving mechanism is that when a driver drives the vehicle to the position above the lifting charging pile 1, the positions of the lifting charging pile 1 and the charging receiving cavity 2 possibly deviate to a certain extent, at the moment, the bottom turntable 9 rotates, the servo linear module drives the self-rotating disc 11 to radially move along the bottom turntable, so that the self-rotating disc 11 can be moved to any position of the rotating range of the bottom turntable 9 through the combination of the two movements, meanwhile, the self-rotating disc 11 rotates, when the infrared sensing device 12 on the top surface of the lifting charging pile 1 corresponds to the position of the infrared sensing device 12 on the top surface of the charging receiving cavity 2, the centering driving mechanism stops working, at the moment, the lifting charging pile 1 and the charging receiving cavity 2 finish alignment, and the lifting mechanism 4 drives the lifting charging pile 1 to ascend into the charging receiving cavity 2. In order to further enable the lifting charging pile 1 to enter the charging receiving cavity 2, proper distance can be ensured between each side face, guide wheels 13 and guide grooves 14 are arranged on the side walls of the lifting charging pile 1 and the charging receiving cavity 2, in the embodiment, vertical T-shaped guide grooves 14 are arranged on the side faces of the lifting charging pile 1, guide wheels 13 are arranged on the side walls of the charging receiving cavity 2, wheel shafts of the guide wheels 13 are perpendicular to the side walls of the charging receiving cavity 2, and in the lifting charging pile 1 lifting process, the T-shaped guide grooves 14 and the guide wheels 13 are matched to guide the lifting charging pile 1 to keep proper gaps with the charging receiving cavity 2, so that the coupling distance between the transmitting antenna 5 and the receiving antenna 3 is further ensured, and the charging effect is improved.
