[0036] The embodiment discloses a full-package back clip, which is used in cooperation with a mobile terminal such as a mobile phone, and can meet the requirement of additional communication mode without replacing the mobile terminal, has low use cost, and has wide application range.

[0037] As shown in Figures 1 to 5 The full-package back clip comprises a back clip main body 1 and a charging interface 3. The back clip main body 1 comprises a bottom plate 11 and an annular frame 12, the annular frame 12 is connected to one side of the bottom plate 11, and the bottom plate 11 and the annular frame 12 jointly enclose a single-face-open slot structure for placing the mobile terminal 2.

[0038] The charging interface 3 is movably arranged in the charging gap 13. When the mobile terminal 2 is taken out of or placed into the slot structure, the charging interface 3 is withdrawn outward along the charging gap 13 to avoid interference with the mobile terminal 2; when the mobile terminal 2 is located in the slot structure, the charging interface 3 is reset and connected with the charging part 21 of the mobile terminal 2. Neither the installation of the mobile terminal 2 through the slot structure and the back clip main body 1 nor the plug connection of the charging interface 3 and the mobile terminal 2 is affected, the full-package structure provides a basis for the structure provided with a bearing antenna, has wider application range, and the product is more competitive.

[0039] The specific shape of the charging interface 3 is not limited, and it can move relative to the back clip main body 1. In the embodiment, as shown in Figure 2 , Figures 4 to 7As shown, the charging interface 3 comprises an interface body 31 and a connector 37 connected with each other, wherein the connector 37 is used to connect with the charging part 21 of the mobile terminal 2. The bottom surface of the interface body 31 is provided with a sliding piece 32, and the back clip body 1 is provided with a sliding groove 14, the sliding piece 32 is arranged in the sliding groove 14 and can move along the sliding groove 14. When the charging interface 3 moves relative to the back clip body 1, the sliding piece 32 moves in the sliding groove 14, the extension direction of the sliding groove 14 is the sliding direction of the sliding piece 32, and also is the moving direction of the charging interface 3 relative to the back clip body 1.

[0040] The specific shape of the sliding piece 32 and the sliding groove 14 is not limited, and the moving direction of the charging interface 3 can be limited. In order to avoid the lateral swing of the charging interface 3, the bottom surface of the interface body 31 is provided with two groups of sliding pieces 32, and the back clip body 1 is provided with two parallel sliding grooves 14, each group of sliding pieces 32 is arranged in one sliding groove 14, which can avoid the lateral swing of the charging interface 3 due to the rotation of the sliding piece 32 around its own axis, and the movement of the charging interface 3 is more smooth.

[0041] On the basis of the above structure, the side surface of the interface body 31 is provided with a charging retreat piece 33, and the back clip body 1 is provided with a back clip retreat groove 15, and the charging retreat piece 33 is embedded in the back clip retreat groove 15. In the process of the charging interface 3 withdrawing outward along the charging aperture 13, the charging retreat piece 33 moves along the back clip retreat groove 15. One end of the back clip retreat groove 15 is in a closed state, and when the charging retreat piece 33 abuts against the closed end of the back clip retreat groove 15, the charging interface 3 stops continuing to withdraw outward, which can avoid that the charging interface 3 withdraws too much and separates from the back clip body 1, and the use is more convenient.

[0042] As shown, Figures 6 to 9 The full-encapsulation back clip further comprises a resilient device 4. The resilient device 4 is used to apply a force to the charging interface 3 to move towards the center of the slot-shaped structure, so that the charging interface 3 can be reset more quickly and labor-savingly, and the use experience is good.

[0043] The specific shape of the resilient device 4 is not limited, and the resilient device 4 can apply a pushing force to the charging interface 3. In the embodiment, the resilient device 4 is a columnar spring arranged in the sliding groove 14, and the extension direction of the spring is consistent with the extension direction of the sliding groove 14. One end of the resilient device 4 abuts against the wall surface of the sliding groove 14, and the other end abuts against the sliding piece 32. When the user pushes the charging interface 3 to withdraw outward along the charging aperture 13, the sliding piece 32 moves to the right in the middle of the sliding groove 14 under the pushing of the resilient device 4, and the resilient device 4 is in an elastic compression state. Figure 9 When the user releases the mobile terminal 2 after putting it into the slot-shaped structure, the pushing force of the charging interface 3 outward along the charging aperture 13 is lost, the resilient device 4 releases the elastic force, and thus pushes the sliding piece 32 to move to the left in the middle of the sliding groove 14, so as to reset the charging interface 3. Figure 9 ​

[0044] As shown in Figure 4 and Figure 5 , the back clip main body 1 is provided with a first accommodating hole 16; as shown in Figure 7 , the charging interface 3 is provided with a second accommodating hole 34. One end of the connecting piece is arranged in the first accommodating hole 16, and the other end of the connecting piece is arranged in the second accommodating hole 34, which is used to electrically or signally connect the charging interface 3 to the back clip main body 1, so that the charging interface 3 and the back clip main body 1 form an integral structure.

[0045] On the basis of the above structure, as shown in Figures 4 to 7 , the top surface of the interface main body 31 is provided with a hand holding portion 35. When it is needed to make the charging interface 3 exit outward along the charging gap 13, the user can hold the hand holding portion 35 with hand and apply force, so as to move the charging interface 3 along the charging gap 13. The hand holding portion 35 protrudes from the top surface of the interface main body 31, which is convenient for applying force and good in use experience.

[0046] When the position of the hand holding portion 35 is not convenient for applying force or the user himself does not have the ability to hold the hand holding portion 35, a hand holding through hole 36 can be arranged on the hand holding portion 35. A knife tip or a thin hard sheet can be inserted into the hand holding through hole 36, and applying force to the knife or the hard sheet can move the charging interface 3.

[0047] In order to avoid the charging interface 3 from being bumped, as shown in Figure 2 , Figure 3 and Figure 10 , the full-encapsulation back clip further comprises a protection piece 5. The protection piece 5 is connected to the back clip main body 1 and located at the charging gap 13, and the protection piece 5 and the back clip main body 1 jointly enclose a space for accommodating the charging interface 3. That is, the protection piece 5 shields at least part of the area on the top of the charging gap 13, and external objects can only hit the protection piece 5, rather than allowing external objects to directly hit the charging interface 3, thereby prolonging the service life of the charging interface 3.

[0048] The specific processing mode of the protection piece 5 is not limited. A through hole can be dug out at the bottom edge of the annular frame 12, which is the charging gap 13. The protection piece 5 and the annular frame 12 are an integral structure, which is more stable in connection and does not need to worry about the separation of the protection piece 5 and the annular frame 12.

[0049] The protection piece 5 can also be a separate structure from the annular frame 12, which is more convenient to process. In the embodiment, the protection piece 5 comprises a protection piece main body 51, and the back surface of the protection piece main body 51 is provided with a mounting column 52. The back clip main body 1 is provided with a protection piece mounting groove 17, and the mounting column 52 is arranged in the protection piece mounting groove 17 and connected, which is convenient for installation and more stable in integral structure.

[0050] On the basis of the above structure, the width of the protector main body 51 is less than the width of the annular frame 12 at the charging gap 13, which can avoid the handhold 35 being blocked by the protector main body 51 when the charging interface 3 moves, and does not affect the normal movement of the charging interface 3. The top surface of the charging interface 3 is attached to the bottom surface of the protector main body 51, which avoids foreign matters entering the gap between the charging interface 3 and the protector main body 51, is convenient for cleaning, and has good use experience.

[0051] It should be noted that the above are only preferred embodiments of the present application and the technical principles used. Those skilled in the art will understand that the present application is not limited to the specific embodiments described herein, and those skilled in the art can make various obvious changes, re-adjustments and substitutions without departing from the scope of the present application. Therefore, although the present application has been described in more detail through the above embodiments, the present application is not limited to the above embodiments, and can include more other equivalent embodiments without departing from the concept of the present application, and the scope of the present application is determined by the scope of the appended claims.
