The charging cable 22 moves right when the supporting plate 19 moves right, and can be automatically shortened and recovered when the supporting plate 19 moves left.

[0040] According to an optional implementation of the present invention, a handle 8 is fixedly connected to the door body 6, and the handle 8 facilitates the user to move the door body 6 up and down.

[0041] According to an optional implementation of the present invention, the handle 8 is provided with a concave-convex portion, which can increase the friction between the user's hand and the handle 8, making it easier for the user to move the handle 8.

[0042] Implementation process:

[0043] In the initial state, the mobile phone 23 extends out of the first cavity 3, and the permanent magnet block 51 is inserted into the limit groove 49 under the elastic force of the fourth elastic member 52 to limit the support plate 19, and the top wall of the door body 6 is against the bottom wall of the support plate 19 under the self-resetting force of the automatic reset gear 9.

[0044] The user can use the mobile phone 23 to scan the QR code and select the normal charging mode or the temporary storage charging mode. When the normal charging mode is selected, one of the charging posts 2 can be used after payment. When the charging post 2 is powered on, the user can directly use the data cable to plug into the charging post 2 to connect with the mobile phone 23 for charging.

[0045] When the temporary storage charging mode is selected, the user can place the mobile phone 23 on the top wall of the supporting plate 19 and insert the corresponding plug on one of the charging cables 22 into the charging port of the mobile phone 23. After payment, one of the charging cables 22 can be energized, and the electromagnet 53 can be energized for a period of time and then turned off, so that the permanent magnet 51 is sucked into the magnet groove 50 by the electromagnet 53, and the supporting plate 19 loses the limit of the permanent magnet 51. The supporting plate 19 moves to the left and resets under the elastic force of the first elastic member 35, and the mobile phone 23 can enter the first cavity 3 for temporary protection. After the supporting plate 19 moves to the left until it is disengaged and abuts against the door body 6, the door body 6 moves up to abut against the top wall of the first cavity 3 under the self-resetting force of the automatic reset gear 9. When the supporting plate 19 moves to the left, it will drive the first piston body 32 to move to the left. When the first piston body 32 moves to the left, the gas pressure pushes the first one-way valve 44 to connect the gas transmission channel 28, and the gas pressure pushes the second one-way valve 45 to close so that the first external channel 29 is blocked, and the gas enters the first cavity 3. In the second piston chamber 27, the gas pressure pushes the second piston body 36 to move left, and the gas pressure is not enough to push the spur rack 41 upward. The second piston body 36 moves left to drive the connecting piece 24 and the transmission rod 20 to overcome the elastic force of the second elastic member 38 and move left. The transmission rod 20 releases the support for the unlocking block 18, and the unlocking block 18 falls below the transmission rod 20. The unlocking block 18 will slow down its falling speed when passing through the elastic buffer strip 48. When the second piston body 36 moves left to push the third wedge block 39 to move upward, it drives the spur rack 41 to move upward, and drives the T-shaped rack 301 to move downward through the transmission gear 302, so that the gas in the second piston chamber 27 is discharged through the second external passage 30, and the second piston body 36 moves right and resets under the elastic force of the second elastic member 38, and the third wedge block 39 moves downward and resets under the elastic force of the third elastic member 42, and the T-shaped rack 301 moves upward to re-block the second external passage 30, and the elastic buffer block 43 can slow down the downward movement speed of the third wedge block 39.

[0046] After the unlocking block 18 slowly falls through the elastic buffer strip 48, it will push the first wedge block 11 to move right, so that the embedding piece 13 is inserted into the fixing groove 16, and the embedding piece 13 and the press-type elastic self-locking mechanism are locked. Then the embedding piece 13 and the second wedge block 12 rebound a short distance, and the limit strip 14 limits the automatic reset gear 9 to prevent others from moving the door body 6 and stealing the mobile phone 23. The unlocking block 18 falls on the receiving plate 47, and the user can take away the receiving plate 47.

[0047] When the mobile phone 23 needs to be retrieved, the unlocking block 18 is aligned with the unlocking channel 4 and inserted. The shape of one unlocking block 18 is only adapted to one unlocking channel 4. When the unlocking block 18 falls, it will push the second wedge block 12 to move right a short distance, thereby releasing the lock of the embedded piece 13 and the press-type elastic self-locking mechanism. The first wedge block 11 moves left and resets under the elastic force of the fifth elastic member 101 and re-extends into the unlocking channel 4. The limit bar 14 releases the limit on the automatic reset gear 9, and the user can pull down the handle 8, move the supporting plate 19 to the right, and then take out the mobile phone 23.

[0048] When the support plate 19 moves to the right, the first one-way valve 44 blocks the air transmission channel 28, and the second one-way valve 45 opens under the action of the pressure difference to connect the first external channel 29 to facilitate the entry of air into the first piston chamber 26. After the support plate 19 extends out of the first cavity 3, the permanent magnet block 51 is inserted into the limit groove 49 for limiting under the elastic force of the fourth elastic member 52, and the handle 8 is released. The self-resetting force of the automatic reset gear 9 causes the top wall of the door body 6 and the bottom wall of the support plate 19 to abut against each other, completing the reset.

[0049] The first cavity 3 , the unlocking channel 4 , the transmission cavity 46 , and the second cavity 17 can be installed with a plurality of them according to actual requirements, so as to store a plurality of mobile phones 23 .

[0050] The present invention can perform ordinary charging and temporary storage charging on the mobile phone 23. The temporary storage charging can temporarily store the mobile phone 23 through the door body 6, so that the user can temporarily leave the charging station. The shapes of the unlocking channel 4 and the unlocking block 18 are adapted. By setting the unlocking channels 4 of different shapes, each unlocking block 18 corresponds to each unlocking channel 4 one by one. One unlocking block 18 can only enter one unlocking channel 4 for unlocking. The unlocking function is realized by using the unlocking block 18, that is, the lock of the limit bar 14 on the automatic reset gear 9 and the door body 6 is released, and the unlocking process is not allowed to consume electricity, so that the user can unlock the charging station and take out his own mobile phone 23 without the mobile phone 23 in hand, and there is no need to press the password to prevent forgetting the password.

[0051] The components, modules, mechanisms and devices not described in detail in the present invention are all universal standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
