Description
Technical Field
The utility model relates to a magnetic force technical field that charges, concretely relates to magnetic force charging base.
Background
The conventional electronic watch is provided with a multipurpose electromagnetic charging base, but the charging base has a small interface and is easy to bump and fall or generate small displacement in the using process, so that the charging is interrupted, and the user experience is not good enough; in addition, many watches adopt a magnet adsorption test mode to contact and charge, and a magnet is arranged at a charging end of a data line, but the magnet of the base is weak, so that the adsorption of the watch and the magnet of the data line is unstable, and the problem of incapability of charging is caused.
Therefore, a magnetic charging base capable of effectively fixing the charging device during charging is needed.
SUMMERY OF THE UTILITY MODEL
To the not enough of prior art, the utility model aims at providing a magnetic charging base.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a magnetic charging base comprises a shell and a charging wire which are connected with each other, wherein a magnetic attraction device is arranged in the shell and is electrically connected with the charging wire; the magnetic attraction device comprises a magnet and a coil, the coil is wound on the magnet, and the coil is electrically connected with the charging wire; the top of shell is provided with a plurality of contacts that charge, the contact that charges with the one end electric connection of charging wire.
The magnet is a high coercive force magnet.
It should be noted that the top surface and the bottom surface of the housing are parallel.
The other end of the charging wire is connected to a power supply.
The beneficial effects of the utility model reside in that:
1. a magnetic charging socket can be effectively fixed on electronic equipment when the electronic equipment is charged.
2. When the charging wire is pulled out from the power supply, the electronic equipment can be easily taken down from the charging socket.
Drawings

fig. 2 is a schematic structural view of the magnetic attraction device in fig. 1.
Detailed Description
The present invention will be further described with reference to the accompanying drawings, and it should be noted that the present embodiment is based on the technical solution, and the detailed embodiments and the specific operation processes are provided, but the protection scope of the present invention is not limited to the present embodiment.
The embodiment provides a magnetic charging base, as shown in fig. 1 and fig. 2, the magnetic charging base includes a housing 11 and a charging wire 12, which are connected to each other, a magnetic attraction device 2 is disposed in the housing 11, the magnetic attraction device 2 includes a magnet 21 and a coil 22, the coil 22 is wound on the magnet 21, and the coil 22 is electrically connected to the charging wire 12; the top of shell 11 is provided with a plurality of charging contacts 111, charging contacts 111 with the one end electric connection of charging wire 12.
In the above structure, the charging contact is used for connecting an electronic device to be charged; when the charging wire is connected with a power supply, a magnetic field generated by the coil after current passes is superposed on the original magnetic field of the magnet, so that the magnetic attraction device generates larger magnetic attraction force, and the charging base can be better attracted to the electronic equipment; it should be noted that the electronic device should be provided with a connection contact adapted to the charging contact, and the connection contact is made of a metal material; when the magnetic attraction device generates magnetic force, a certain attraction force can be generated on all metal materials on the electronic equipment, and finally the charging base and the electronic equipment are attracted tightly, so that the charging contact and a connecting contact on the electronic equipment are kept in stable and good contact; similarly, when the charging wire is disconnected with the power supply, no current passes through the coil, and the magnetic attraction force of the magnetic attraction device is weakened; the shell is made of an insulating material, so that the power utilization safety can be effectively guaranteed in the process of using the magnetic charging seat.
In the present embodiment, as shown in fig. 2, the magnet 21 is a high coercive force magnet. The high-coercivity magnet has good demagnetization resistance, and can ensure that the magnetic force cannot disappear easily when the charging base is used.
In this embodiment, as shown in fig. 1, the top surface and the bottom surface of the housing 11 are parallel. When the bottom surface of the shell is contacted with the placing surface, the top surface of the shell is provided with a charging contact, so that the working state of the charging base is more stable when the charging base charges the electronic equipment, and the top surface and the bottom surface of the shell are in a parallel state, so that the effect is best.
In this embodiment, as shown in fig. 1, the other end of the charging wire 12 is connected to a power supply.
When the user uses the magnetic charging socket: the charging base is placed on a relatively stable placing surface, then the charging wire is connected with a power supply, the magnetic attraction device generates relatively large magnetic attraction force after being electrified, and at the moment, the electronic equipment is close to the shell of the charging base and is electrically connected with the charging contact; the magnetic attraction makes the charging base and the electronic equipment tight box paste.
When charging is finished, the charging wire is pulled out of the power supply, the magnetic attraction force of the magnetic attraction device becomes weak, and the electronic equipment can be easily taken away from the charging base.
Various corresponding changes and modifications can be made by those skilled in the art according to the above technical solutions and concepts, and all such changes and modifications should be included in the protection scope of the present invention.
