the three-connecting-rod structure comprises an upper connecting rod 2 and a lower connecting rod 4 which are movably connected with the shell 1, and a synchronizing rod 3 which is movably connected with the upper connecting rod 2 and the lower connecting rod 4 respectively;

The synchronizing bar 3 is arranged to move synchronously with the upper link 2 when the article 9 is inserted into the cavity and to rotate relative to the upper link 2 when the article 9 is removed from the cavity.

The upper connecting rod 2, the synchronizing rod 3 and the lower connecting rod 4 form a three-connecting-rod structure, the synchronizing rod 3 can synchronously move with the upper connecting rod 2 and move relative to the lower connecting rod 4 in the inserting stage of the article 9, and the article 9 is ensured to be smoothly inserted into the cavity of the shell 1 through the relative rotation of the synchronizing rod 3 and the lower connecting rod 4. Simultaneously, the synchronizing rod 3 can rotate relative to the upper connecting rod 2 in the taking-out stage of the article 9, so that the lower connecting rod 4 has a larger movement range relative to the two-connecting-rod structure under the drive of the synchronizing rod 3, interference to the article 9 and protruding structures 901 such as a camera and a protective shell step of the article is avoided, and smooth taking-out of the article 9 from the cavity is ensured.

Since a downward pressure is applied to the synchronizing bar 3 when the article 9 is inserted downward, the counterclockwise rotation of the second rotation member 8 is restricted, ensuring that the synchronizing bar 3 remains relatively stationary and moves synchronously with the upper link 2 after the article 9 is forced during the insertion stage.

Referring to fig. 1 to 14, taking the insertion and extraction of a mobile phone as an example, the application method and the working principle of the utility model are as follows:

Referring to fig. 10 and 11, the insertion phase:

When the mobile phone is inserted into the cavity of the shell 1 downwards, the end part of the mobile phone is pressed against the synchronizing rod 3 downwards, and the mobile phone can be inserted downwards smoothly by utilizing the first guide cambered surface of the synchronizing rod 3.

During the insertion process, the third limiting surface 31 of the synchronizing rod 3 abuts against the second limiting surface 22 of the upper connecting rod 2, and the plane abutting is utilized to enable the synchronizing rod 3 to keep relative static with the upper connecting rod 2 and push the upper connecting rod 2 to synchronously rotate, so that the upper connecting rod 2 rotates anticlockwise around the first rotating piece 6. At this time, the first elastic member is pressed to store force, and the first limiting surface 21 is separated from the outer wall of the housing 1.

The lower connecting rod 4 is driven to move by the rotation of the synchronizing rod 3 while the synchronizing rod 3 and the upper connecting rod 2 synchronously rotate, and the linkage process of the lower connecting rod 4 is that the lower connecting rod 4 rotates relative to the synchronizing rod 3 through the third rotating piece 41, and the limiting part 42 is limited by the limiting chute 12 to only do up-down linear motion along the limiting chute 12, so that the lower connecting rod 4 slides downwards along the limiting chute 12 while rotating.

The motion track of the synchronizing rod 3 is circular motion around the first rotating member 6, and the lower connecting rod 4 moves downwards under the guide of the limiting chute 12 and rotates relative to the synchronizing rod 3, so that the mobile phone can be inserted into the cavity of the shell 1. After the cell-phone inserts the cavity, the elasticity that first elastic component compression formed loops through last connecting rod 2, synchronizing lever 3 and lower connecting rod 4 to on the cell-phone to compress tightly the laminating with the cell-phone through lower connecting rod 4 on the inner wall of casing 1, guarantee the stability of cell-phone and do not rock, and make the cell-phone be close to wireless charging module 101, guarantee wireless validity and the charging efficiency that charges.

Referring to fig. 12 to 14, the removal stage:

if the protruding structure 901 such as the camera of the mobile phone is located at the upper part, as shown in fig. 10, when the mobile phone is pulled out of the housing 1, because the mobile phone is in an abutting state with the lower link 4, when the mobile phone is taken out, an upward force is formed on the lower link 4 by using a friction force, so that the limiting part 42 moves upward along the limiting chute 12 under the force, and the fourth rotating part 302 of the synchronizing bar 3 is driven to move upward and rotate relative to the lower link 4 by the third rotating part 41.

If the protruding structure 901 such as the camera of the mobile phone is located at the bottom, as shown in fig. 12, when the mobile phone is pulled out of the housing 1, the protruding structure 901 such as the camera of the mobile phone pushes the lower link 4 upward, so as to form an upward force on the lower link 4, so that the limiting portion 42 moves upward along the limiting chute 12 under the force, and the third rotating member 41 drives the fourth rotating portion 302 of the synchronizing bar 3 to move upward and rotate relative to the lower link 4.

In the process of moving upwards and rotating the fourth rotating part 302, the synchronizing rod 3 rotates clockwise around the second rotating member 8, at this time, the third limiting surface 31 is separated from the second limiting surface 22, the rotating surface 32 is attached to the second limiting surface 22 in a sliding manner along with the rotation of the synchronizing rod 3, and the rotating surface 32 with an arc surface structure ensures the stable rotation of the synchronizing rod 3 relative to the upper connecting rod 2 and extrudes the second elastic member.

Because the upper connecting rod 2 is abutted against the shell 1 through the first limiting surface 21, the force is unloaded for the first elastic piece, the third limiting surface 31 is separated from the second limiting surface 22, the synchronous rod 3 rotates relative to the upper connecting rod 2 through the rotating contact of the rotating surface 32 and the second limiting surface 31, the second elastic piece is compressed to provide acting force for the article in the rotating process of the synchronous rod 3 relative to the upper connecting rod 2, and the acting force provided by the second elastic piece is smaller than the clamping force provided by the first elastic piece, so that the article and the protruding structure thereof can smoothly pass through the three-connecting-rod structure.

After the mobile phone is taken out, the pressure of the synchronizing rod 3 is relieved, the second elastic piece is used for unloading, the synchronizing rod 3 rotates anticlockwise around the second rotating piece 8 by utilizing the elastic force of the second elastic piece to reset, the third limiting surface 31 is abutted against the second limiting surface 22 of the upper connecting rod 2 again, and the lower connecting rod 41 is in linkage reset with the synchronizing rod 3 through the third rotating piece 41 and the limiting part 42.
