specifically, a sensor may be disposed at an end of the electrified coil, and the sensor may detect whether the conductor antenna completely passes through the electrified coil;
taking the design of two feed points as an example, when there is no object to shield the feed points, the N pole of the conductor antenna is connected to one of the feed points (of course, the S pole may also be connected to one of the feed points, which is illustrated here for convenience of description), at this time, one end of the control module close to the conductor antenna is a positive pole, one end far away from the conductor antenna is a negative pole, and according to ampere' S law, one end of the energizing coil close to the conductor antenna is the S pole, and one end far away from the conductor antenna is the N pole, so that the energizing coil gives a repulsive force to the conductor antenna to push it to be stably connected to the feed points; when the radio frequency module connected with the feed point detects that the intensity of the feedback signal is lower than the preset intensity of the feedback signal, the feed point is shielded by an object and the signal is weaker, at the moment, the current direction given to the electrified coil is changed through the control module, the end, close to the conductor antenna, of the electrified coil is changed into the N pole, the end, far away from the conductor antenna, of the electrified coil is the S pole, at the moment, the electrified coil gives the conductor antenna an attractive force to pull the electrified coil to be disconnected with the feed point connected at present and move towards the direction of the other feed point, when the sensor arranged at the end part of the electrified coil detects that the conductor antenna completely passes through the electrified coil, the current direction given to the electrified coil is changed through the control module again, the end, close to the conductor antenna, of the electrified coil is changed into the N pole, the end, far away from the conductor antenna is the S pole, at the moment, the electrified coil gives a repulsive force to the conductor antenna, causing it to move rapidly to another feed point and to communicatively connect therewith.
Taking the design of two feed points as an example, when there is no object to shield the feed points, the N pole of the conductor antenna is connected to one of the feed points (of course, the S pole may also be connected to one of the feed points, which is illustrated here for convenience of description), at this time, one end of the control module close to the conductor antenna is a positive pole, one end far away from the conductor antenna is a negative pole, and according to ampere' S law, one end of the energizing coil close to the conductor antenna is the S pole, and one end far away from the conductor antenna is the N pole, so that the energizing coil gives a repulsive force to the conductor antenna to push it to be stably connected to the feed points; when the radio frequency module connected with the feed point detects that the intensity of the feedback signal is lower than the preset intensity of the feedback signal, the feed point is shielded by an object and the signal is weaker, at the moment, the current direction given to the electrified coil is changed through the control module, the end, close to the conductor antenna, of the electrified coil is changed into the N pole, the end, far away from the conductor antenna, of the electrified coil is the S pole, at the moment, the electrified coil gives the conductor antenna an attractive force to pull the electrified coil to be disconnected with the feed point connected at present and move towards the direction of the other feed point, when the sensor arranged at the end part of the electrified coil detects that the conductor antenna completely passes through the electrified coil, the current direction given to the electrified coil is changed through the control module again, the end, close to the conductor antenna, of the electrified coil is changed into the N pole, the end, far away from, causing it to move rapidly to another feed point and to communicatively connect therewith.
When the number of the feed points is larger than two, taking the design of three feed points as an example, when no object covers the feed points, the N pole of the conductor antenna is connected with the feed point arranged in the middle, and the S pole is a free end, at this time, in order to ensure that the conductor antenna is stably connected with the feed points, at this time, the control modules arranged at the two ends of the conductor antenna are controlled to supply the current directions to the electrified coils to be the same, namely, the two electrified coils simultaneously supply the conductor antenna repulsive force, so that the conductor antenna is stably connected with the feed points, the displacement change is avoided when the mobile terminal moves, when the radio frequency module detects that the intensity of the feedback signal arranged at the leftmost feed point is strongest, the current supplied to the electrified coil by the control module at the left end of the conductor antenna is changed again to ensure that the attractive force supplied to the conductor antenna is changed into attractive force, at this time, the conductor antenna is under the combined action of the electrified coil at the left end and the preferential electrified coil repulsive force, disconnected from the center-located feedpoint, and moved rapidly to and communicatively connected with the leftmost feedpoint.
The method and the device can realize the independent recognition of the feedback signal intensity of all the feed points, move the conductor antenna to the feed point with the strongest feedback signal intensity and are in communication connection with the feed point, and therefore the signal stability of the mobile terminal is realized.
