Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

An apparatus for rapidly detecting charging parameters of a charger, comprising: the device comprises a parameter acquisition structure for acquiring charger parameters of the charger and a connector conversion structure for connecting the charger and the parameter acquisition structure. The connector conversion structure comprises a rotating plate 11, a butt joint lead 12 and a shell 13. The housing 13 is sleeved on the rotating plate 11 so that the rotating plate 11 can rotate with the central axis of the rotating plate as an axis. The docking lead 12 extends into the shell 13 through the parameter acquisition structure, and reinforcing ribs corresponding to the docking lead 12 are arranged in the shell 13. The shell 13 is also provided with an arc-shaped curved surface to fit the holding hand shape of the palm part of the human body. One end of the docking wire 12 is electrically connected to the input port 24 of the parameter obtaining structure, the other end of the docking wire 12 is provided with a conductive groove 122, and a conductive protrusion 121 is embedded in the conductive groove 122. The inner wall of the conductive groove 122 is made of a conductive material, so that the conductive groove 122 can be electrically connected with the conductive bump 121. A spring 123 is arranged between the conductive protrusion 121 and the bottom of the conductive groove, and one end of the conductive protrusion 121 away from the spring 123 is conical, so that one end of the conductive protrusion 121 away from the spring 123 has an inclined plane, and one end of the conductive protrusion in a conical shape protrudes out of the conductive groove 122. Wherein, a plurality of sets of through holes 112 corresponding to the conductive protrusions 121 are arranged on the rotating plate 11, and when the through holes 112 are located at the positions corresponding to the conductive protrusions 121, the conductive protrusions 121 can pass through the through holes 112. The rotating plate 11 is further provided with a plurality of joints 111, the joints 111 correspond to the through holes 112 one by one, and distances from the joints 111 to the circle center of the rotating plate 11 are equal, so that the joints 111 are located on the same circumference, and further, one of the joints 111 can be rotated to a position corresponding to the butt-joint conducting wire 12 under the rotation of the rotating plate 11. Wherein, a socket for butting with a charger plug is arranged on the joint 111, and one end of the joint 111 close to the rotating plate 11 is provided with a conductive contact 1111 corresponding to the conductive protrusion 121. Conductive contacts 1111 are electrically connected to the jack.

In actual use, one of the plurality of taps 111 is located at a position corresponding to the docking wire 12 by default. At this time, one end of the conductive protrusion 121, which is conical, protrudes out of the conductive groove 122, so as to pass through the through hole 112 on the rotating plate 11, and further, the conductive contact 1111 on the connector 111 is abutted, so that the connector 111 can be electrically connected to the docking wire 12, and further, can be electrically connected to the parameter acquisition structure. When the charger parameters of the charger need to be acquired, the connector 111 of the model corresponding to the plug of the current charger needs to be selected. If the type of the connector 111 currently located at the docking wire 12 does not correspond to the plug type of the charger, a force is applied to the connector 111 to rotate the rotating plate 11 around the central axis of the rotating plate 11, so that the connector 111 and the rotating plate 11 rotate together. During the rotation of the rotating plate 11, the inner wall of the through hole 112 disposed on the rotating plate 11 will press the conductive protrusion 121, and under the action of the inclined slope of the conductive protrusion 121, the conductive protrusion 121 will be forced to slide toward the bottom of the conductive groove 122, so that the conductive protrusion 121 is disengaged from the through hole 112 and the conductive contact 1111. During sliding of the conductive protrusion 121, the spring 123 will be compressed. The rotation plate 11 is further rotated until the through opening 112 corresponding to the next contact 111 is rotated to the conductive protrusion 121. At this time, under the elastic force of the spring 123, the conductive protrusion 121 springs out of the conductive groove 122, and then passes through the through hole 112 to abut against the conductive contact 1111, at which time, the conductive protrusion 121 will hinder the rotation of the rotating plate 11 to some extent. Meanwhile, under the influence of the elastic force of the spring 123, when the conductive protrusion 121 abuts against the conductive contact 1111, a "click" sound is generated. The user will be alerted by the sound and tactile feedback of the operation that the tab 111 has been rotated to the position corresponding to the docking wire 12. The above process is repeated until the contact 111 corresponding to the charger plug type is rotated to a position corresponding to the docking wire 12. Wherein, the quantity of joint 111 is 3 at least, including vertical article word joint, horizontal article word joint, round hole article word joint in order to adapt to the present most charger on the market.

After the connector 111 is adjusted, a plug on the charger for electrically connecting with the mains supply is electrically connected with the output port 25 of the parameter acquisition structure, and a plug on the charger for electrically connecting with the storage battery is electrically connected with the connector 111. Wherein, the parameter acquisition structure further comprises: direct current power supply 21, direct current electronic load 22, current limiting resistor 23. The dc power supply 21 is electrically connected to the current limiting resistor 23, the dc power supply is connected in parallel to the dc electronic load 22, and the dc electronic load 22 is electrically connected to the input port 24 and the output port 25.

After the charger is electrically connected with the parameter acquisition structure, voltage is provided for the charger through the direct current power supply 21 to simulate the initial state of the battery, meanwhile, the direct current power supply 21 provides voltage for the current limiting resistor 23, on one hand, the current limiting resistor 23 activates the charger by using the voltage, and on the other hand, voltage division protection is performed through the current limiting resistor 23. The behavior of the battery during the charging process is simulated by the dc electronic load 22 in order to simulate the entire charging process, so that the charger is operated according to a predefined charging sequence.
