In this state, it is convenient to view a landscape video or perform other landscape operations while charging.

In the above three use states:

the principle of the first support bar 1 and the second support bar 2 from the parallel state to the perpendicular state is as follows: rotate first branch 1 (because supporting baseplate 12's restriction, first branch 1 can only carry out one-way rotation), make one side of first branch 1 separate with one side of second branch 2 gradually, when first branch 1 is perpendicular with second branch 2, one side of first branch 1 and one side complete separation of second branch 2, cooperation draw-in groove 4 on the first branch 1 also corresponds to with cooperation draw-in groove 4 on the second branch 2 simultaneously, then make two cooperation draw-in grooves 4 block each other under elastic connection 13's resilience, and form the connection status of fig. 5 or fig. 6, under this state, based on the injecing of cooperation draw-in groove 4, first branch 1 and second branch 2 complex stability has effectively been guaranteed, thereby avoid appearing the not hard up or automatic folding problem of retrieving of structure.

The principle of the first strut 1 and the second strut 2 converting from the perpendicular state to the parallel state is as follows: outwards pulls first branch 1, drive overcoat 131 and move outward in step, telescopic inner rod 132 does not produce the removal this moment, then the position of piston 133 has been injectd correspondingly, and make first spring 134 between piston 133 and the overcoat 131 receive tensile, when cooperation draw-in groove 4 on first branch 1 and the cooperation draw-in groove 4 on the second branch 2 break away from, first branch 1 of gyration, so that first branch 1 forms the parallel state that fig. 1 shows with the cooperation of second branch 2, under this state, form the resilience force based on the tensile of first spring 134, thereby produce the straining force that is close to each other to first branch 1 and second branch 2, make one side in close contact with in one side of second branch 2 of first branch 1, form stable positioning.

The principle of rotation and positioning of the upper plate 31 and the lower plate 32 is as follows: referring to fig. 4, at least one of the locking grooves 35 formed in the lower plate 32 is located at a position corresponding to the locking pin 34 when the upper plate 31 and the lower plate 32 are parallel to each other, so that the state shown in fig. 4 is formed, that is, when the upper plate 31 and the lower plate 32 are parallel to each other, one end of the locking pin 34 is locked in the locking groove 35, and the second spring 33 is in an initial state. When the upper plate 31 and the lower plate 32 are rotated, the connecting portion of the upper plate 31 and the lower plate 32 is pushed, and automatic rotation can be formed under the matching of the guiding inclined surfaces and the inner walls of the clamping grooves 35, in fig. 4, when the clamping pins 34 are separated from the clamping grooves 35, the second springs 33 connected with the clamping pins 33 are retracted and deformed, so that the clamping pins 34 and the lower plate 32 are driven to generate rebound pressure under the rebound of the second springs 33, and the rotational positioning between the upper plate 31 and the lower plate 32 is realized based on the rebound pressure. Based on this, the upper plate 31 and the lower plate 32 will rotate only when driven by external force, and in the use state after rotation, neither the upper plate 31 nor the lower plate 32 is used to support the mobile phone, thereby effectively ensuring the stable use of the wireless charging board 3 in the state shown in fig. 6.
