Problems solved by technology

However, because the limit switch is easily touched by other foreign objects, misjudgment may occur, and multiple limit switches will cause high cost and low reliability.
In addition, through microwave, laser and other methods, there are problems such as being easily disturbed by foreign objects, and the equipment is complex and easy to damage.

example 1

[0028] Example 1: as Figure 4 and 5 As shown, the coil 3 wound on the magnetic conductor 2 includes a row coil 32 and a column coil 31, the row coil 32 is located above, the column coil 31 is located below, N1+N2 electromotive force detection circuits 6, and the electromotive force detection circuit 6 uses a voltage Or a current sensor, the coils 31 of the two columns of the magnetizers located in the same column are connected in series, and then connected to an electromotive force detection circuit 6, and the coils 32 of the two columns of magnetizers located in the same row are connected in series in sequence, and then connected to an electromotive force detection circuit 6.

[0029] The working method is as follows: when the separable transformer generates an alternating magnetic field, an alternating magnetic flux will be generated on the magnetic conductor 2 that is approaching or contacting, and the row coil 32 and the column coil 31 will generate an induced electromoti...

example 2

[0030] Example 2: as Image 6 As shown, the coils 3 wound on the magnetic conductor 2 can be a group, N1+N2 electromotive force detection circuits 6, the electromotive force detection circuit 6 adopts a voltage or current sensor, and the coils 3 of the magnetic conductor 2 in the same column / row are connected in series with For the diodes 7, all the series branches are connected in parallel to the electromotive force detection circuit 6, and the diodes 7 connected in series with the coils 3 of the magnetizers 2 in the same column / row have the same conduction direction.

[0031] The working method is as follows: when the separable transformer generates an alternating magnetic field, an alternating magnetic flux will be generated on the magnetic conductor 2 that is approaching or contacting, and the coil 3 will generate an induced electromotive force. When the voltage or current sensor is detected in the row or column, the row or column where the induced voltage or current is lo...

Abstract

The invention discloses a magnetic guide plate for positioning a separable transformer, which includes a support plate and a plurality of magnet guides, a plurality of through holes are opened on the support plate, a coil is wound on the magnet guide, and the coil is connected with an electromotive force detection circuit , a magnetic conductor wound with a coil is embedded and fixed in the through hole. When charging, alternating magnetic flux is generated on the magnetic conductor close to the separable transformer, and alternating electromotive force is generated in the corresponding coil. The alternating electromotive force generated by the magnetic conductor coil is detected by the electromotive force detection circuit, so that it can be judged The position where the separation transformer is attached to the magnetic plate; because the induction is the magnetic field generated by the separation transformer, the identification degree is high, and it is not easily affected by foreign objects and other interference; and there are no mechanical parts and optical parts that are easy to wear and damage. link, so the reliability is higher and the cost is lower.

Description

technical field [0001] The invention relates to a magnetic conductive plate for positioning a separable transformer, belonging to the technical field of electric vehicle charging. Background technique [0002] The high-power and high-efficiency charging requirements of electric vehicle charging can be achieved through the detachable transformer mode, using the structure of the secondary side of the detachable transformer on the electric vehicle side, the ground directional magnetic guide plate, and the primary side of the ground detachable transformer. The secondary side of the detachable transformer of the electric vehicle automatically falls to the directional magnetic guide plate after parking, and the primary side of the detachable transformer and the secondary side of the detachable transformer are aligned to generate magnetic flux, which is coupled with the secondary side of the detachable transformer through the directional magnetic guide plate , to transmit electrica...
