[0032] Combine the following Figures 1 to 3 The drawer-type charger of the present application is described.

[0033] According to the embodiments of the present application, Figure 1 and Figure 2 As shown, the pull-out charger includes:

[0034] Shell 1;

[0035] A winding assembly 2 is connected to the housing 1, and a winding space is provided between the winding assembly 2 and the housing 1;

[0036] A data line 3 is wound in the winding space;

[0037] A PCB board 5 is fixedly connected to the housing 1;

[0038] A flat cable 4 is disposed in the housing 1 , one end of the flat cable 4 is connected to the connecting end of the data cable 3 , and the other end of the flat cable 4 is fixedly connected to the housing 1 ;

[0039] The winding assembly 2 can switch between a forward rotation state and a reverse rotation state, wherein in the forward rotation state, the winding assembly 2 winds the data line 3 , and in the reverse rotation state, the winding assembly 2 releases the data line 3 .

[0040] According to the pull-out charger of the embodiment of the present application, when the user pulls the data cable 3, the winding assembly 2 is in a reverse rotation state, and the winding assembly 2 will release the data cable 3, so that the portion of the data cable 3 protruding from the housing 1 becomes longer to meet the user's usage needs. When the data cable 3 is pulled out, since one end of the flat cable 4 is connected to the connection end of the data cable 3, one end of the flat cable 4 will also rotate with the winding assembly, that is, one end of the flat cable 4 will rotate with the data cable, so that the flat cable 4 can always connect the PCB board 5 and the data cable 3. At the same time, the other end of the flat cable 4 is fixedly connected to the housing 1, that is, the other end of the flat cable 4 will not move due to the movement of the data cable 3, and the connection between the flat cable 4 and the PCB board 5 will not move or change. Similarly, when the winding assembly 2 winds the data cable 3, the other end of the flat cable 4 will not move. That is to say, the present application realizes a direct connection between the data cable 3 and the PCB board 5 arranged on the shell 1 through the flat cable 4, thereby improving the safety when the current is large. When the data cable 3 moves, that is, when the winding assembly 2 winds or releases the data cable 3, the other end of the flat cable 4 is fixed, and no metal powder is generated, which can effectively avoid the occurrence of short circuits.

[0041] In some embodiments, the other end of the flat cable 4 is fixedly connected to the PCB board 5 .

[0042] It is understandable that the other end of the flat cable 4 is directly fixedly connected to the PCB board 5, and the PCB board 5 is fixedly connected to the housing 1, so that the other end of the flat cable 4 is also fixedly arranged, that is, the connection between the flat cable 4 and the PCB board 5 is fixed.

[0043] In some embodiments, Figure 2 and Figure 3 As shown, the pull-out charger further includes a fixing column 6 , which is fixedly connected to the inner wall surface of the shell 1 , and the other end of the flat cable 4 is fixedly connected to the fixing column 6 .

[0044] It is understandable that the other end of the cable 4 is fixedly connected to the fixing post 6 , and the fixing post 6 is fixedly connected to the housing 1 , so that the other end of the cable 4 is also fixed, avoiding the other end of the cable 4 from moving and causing an impact.

[0045] In some embodiments, Figure 2 and Figure 3 As shown, one end of the fixing column 6 is fixedly connected to the inner wall surface of the housing 1 , and the other end of the fixing column 6 is formed with a clamping groove 61 , and the other end of the flat cable 4 is clamped in the clamping groove 61 .

[0046] It can be understood that by providing a snap-in groove 61 at the other end of the fixing column 6, the other end of the cable 4 can be snapped into the snap-in groove 61, thereby achieving a fixed connection between the other end of the cable 4 and the fixing column 6, making the connection between the other end of the cable 4 and the fixing column 6 easier.

[0047] In some embodiments, Figure 1 and Figure 2 As shown, the housing 1 includes an upper shell 12 and a lower shell 13 , and the upper shell 12 and the lower shell 13 are connected to enclose a mounting cavity 11 , and the winding assembly 2 and the cable 4 are both located in the mounting cavity 11 .

[0048] It is understandable that the winding assembly 2 and the cable 4 are arranged in the installation cavity 11, so as to avoid the winding assembly 2 and the cable 4 from directly contacting the external environment, so that the winding assembly 2 and the cable 4 can work stably without being affected by the outside world.

[0049] In some embodiments, the PCB board 5 is fixedly connected to the upper shell 12 , the fixing column 6 is fixedly connected to the lower shell 13 , and the fixing column 6 abuts against the PCB board 5 .

[0050] It is understandable that when the upper shell 12 and the lower shell 13 are connected, the fixing column 6 and the PCB board 5 abut against each other, so that the fixing column 6 and the PCB board 5 can support each other, thereby improving the structural stability of the pull-out charger.

[0051] In some embodiments, a connection portion is formed at one end of the fixing column 6 close to the PCB board 5 , and the other end of the flat cable 4 is electrically connected to the PCB board 5 through the connection portion.

[0052] It can be understood that the other end of the flat cable 4 is connected to the connecting portion, and the connecting portion is connected to the PCB board 5, thereby realizing the connection between the flat cable 4 and the PCB board 5.

[0053] In some embodiments, Figure 2 and Figure 3 As shown, the lower shell 13 is formed with a plurality of connection blocks 131 , and the connection blocks 131 are evenly distributed along the circumference of the lower shell 13 , and the connection blocks 131 are suitable for connecting with the upper shell 12 .

[0054] It is understandable that the upper shell 12 and the lower shell 13 are connected together by connecting the connecting blocks 131. At the same time, the connecting blocks 131 are evenly distributed along the circumference of the lower shell 13, which improves the uniformity of the connection effect and makes the connection between the upper shell 12 and the lower shell 13 more stable.

[0055] In some embodiments, Figure 2 and Figure 3 As shown, the connection block 131 is formed with a connection protrusion 132 , and the upper shell 12 is formed with a clamping hole 121 , and the connection protrusion 132 is suitable for clamping in the clamping hole 121 .

[0056] It is understandable that the connection protrusion 132 is inserted into the clamping hole 121 so that the connection protrusion 132 and the clamping hole 121 cooperate with each other, thereby connecting the upper shell 12 and the lower shell 13 together.

[0057] In some embodiments, a seal is provided at the connection between the upper shell 12 and the lower shell 13 .

[0058] It can be understood that the seal can improve the sealing performance of the connection between the upper shell 12 and the lower shell 13 to reduce the impact of the external environment on the components in the housing 1.

[0059] In some embodiments, Figure 1 and Figure 2 As shown, the pull-out charger includes:

[0060] The housing 1 is formed with a mounting cavity 11;

[0061] The winding assembly 2 is installed in the installation cavity 11;

[0062] A data line 3 is wound on the winding assembly 2, and the winding assembly 2 is used to wind or release the data line 3;

[0063] The flat cable 4 is arranged in the installation cavity 11 , the other end of the flat cable 4 is fixedly arranged and electrically connected to the PCB board 5 , the connecting end of the data line 3 is connected to one end of the flat cable 4 , and the output end of the data line 3 protrudes from the housing 1 .

[0064] According to the pull-out charger of the embodiment of the present application, the output end of the data cable 3 protrudes from the housing 1, so that the user can directly grasp the data cable 3, so that the user can pull out the data cable 3. When the user pulls out the data cable 3, the winding assembly 2 will release the data cable 3, so that the part of the data cable 3 protruding from the housing 1 becomes longer to meet the user's usage needs. When the data cable 3 is pulled out, since one end of the flat cable 4 is connected to the connecting end of the data cable 3, one end of the flat cable 4 will also rotate with the winding assembly, that is, one end of the flat cable 4 will rotate with the data cable, so that the flat cable 4 can always connect the PCB board 5 and the data cable 3. At the same time, the other end of the flat cable 4 is fixed, that is, the other end of the flat cable 4 will not move due to the movement of the data cable 3, and the connection between the flat cable 4 and the PCB board 5 will not move or change. Similarly, when the winding assembly 2 winds the data cable 3, the other end of the flat cable 4 will not move. That is to say, the present application realizes a direct connection between the data cable 3 and the PCB board 5 through the flat cable 4, thereby improving the safety when the current is large. When the data cable 3 moves, that is, when the winding assembly 2 winds or releases the data cable 3, the other end of the flat cable 4 is fixed, and no metal powder is generated, which can effectively avoid the occurrence of short circuits.

[0065] In some embodiments, a winding space is formed between the winding assembly 2 and the inner wall surface of the installation cavity 11, and the data line 3 is wound in the winding space.

[0066] It can be understood that a winding space is provided between the winding assembly 2 and the inner wall surface of the installation cavity 11 , thereby facilitating the winding of the data cable 3 .

[0067] In some embodiments, Figure 2 and Figure 3 As shown, the winding assembly 2 is formed with a receiving cavity 21 , and the cable 4 is disposed in the receiving cavity 21 .

[0068] It can be understood that arranging the flat cable 4 in the accommodating cavity 21 of the winding assembly 2 improves the utilization of the space of the winding assembly 2 and is conducive to the simplification of the structure of the pull-out charger.

[0069] In some embodiments, Figure 2 and Figure 3 As shown, the flat cable 4 is wound in the accommodating cavity 21 .

[0070] It is understandable that the flat cable 4 is wound in the accommodating cavity 21 . When the winding assembly 2 winds or releases the data cable 3 , the flat cable 4 will also be wound or released, thereby preventing the flat cable 4 from being chaotically distributed in the accommodating cavity 21 .

[0071] In some embodiments, Figure 2 and Figure 3As shown, the winding assembly 2 includes a winding rotor 22 and a reset member 23. The winding rotor 22 is installed in the installation cavity 11. The winding rotor 22 can rotate relative to the shell 1. The reset member 23 is connected to the winding rotor 22. The reset member 23 is used to drive the winding rotor 22 to reset.

[0072] It can be understood that the winding rotor can rotate relative to the housing 1, and the data cable 3 is wound around the winding rotor, and then the winding rotor can wind or release the data cable 3. When the user pulls the data cable 3, that is, when the data cable 3 is subjected to an outward pulling force, the winding rotor releases the data cable 3, and when the user no longer pulls the data cable 3, or the data cable 3 is no longer subjected to an outward pulling force, the reset member 23 drives the winding rotor to reset, so that the winding rotor winds the data cable 3, and the data cable 3 is automatically wound.

[0073] In some embodiments, Figure 2 and Figure 3 As shown, the reset member 23 includes an elastic spring 231 , a first end of the elastic spring 231 is fixedly connected to the housing 1 , and a second end of the elastic spring 231 is connected to the winding rotor 22 .

[0074] It can be understood that when the user pulls the data cable 3, that is, when the data cable 3 is subjected to outward pulling force, the winding rotor releases the data cable 3, and the elastic spring 231 is compressed as the winding rotor rotates. When the user no longer pulls the data cable 3, or the data cable 3 is no longer subjected to outward pulling force, the elastic spring 231 restores its deformation and applies an elastic force to the winding rotor, so that the elastic spring 231 can drive the winding rotor to reset, so that the winding rotor winds up the data cable 3, thereby realizing automatic winding of the data cable 3.

[0075] In some embodiments, the reset member 23 includes a reset spring, a first end of the reset spring is fixedly connected to the housing 1 , and a second end of the reset spring is connected to the winding rotor 22 .

[0076] It can be understood that when the user pulls the data cable 3, that is, when the data cable 3 is subjected to outward pulling force, the winding rotor releases the data cable 3, and the reset spring is compressed as the winding rotor rotates. When the user no longer pulls the data cable 3, or the data cable 3 is no longer subjected to outward pulling force, the reset spring restores its deformation and applies an elastic force to the winding rotor, so that the reset spring can drive the winding rotor to reset, so that the winding rotor winds up the data cable 3, thereby realizing automatic winding of the data cable 3.

[0077] In some embodiments, Figure 2 and Figure 3As shown, the winding rotor 22 includes a base plate 221 and an annular winding plate 222, the base plate 221 is connected to the reset member 23, the annular winding plate 222 is fixedly connected to the base plate 221, the reset member 23 and the annular winding plate 222 are located on different sides of the base plate 221, and the data line 3 is wound around the annular winding plate 222.

[0078] It is understandable that the bottom plate 221 is rotatably disposed on the housing 1, and the reset member 23 is connected to the bottom plate 221, which can drive the bottom plate 221 to reset. The data line 3 is wound on the annular winding plate 222, and when the bottom plate 221 rotates relative to the housing 1, the annular winding plate 222 will wind or release the data line 3. The reset member 23 and the annular winding plate 222 are respectively arranged on different sides of the bottom plate 221, while avoiding mutual interference between the reset member 23 and the annular winding plate 222, and can also achieve a rational structure distribution and effective use of the space of the housing 1.

[0079] In some embodiments, Figure 2 and Figure 3 As shown, the flat cable 4 is wound on the inner side of the annular winding plate 222 , and the data cable 3 is wound on the outer side of the annular winding plate 222 .

[0080] It is understandable that the flat cable 4 is wound on the inner side of the annular winding plate 222 , and the data cable 3 is wound on the outer side of the annular winding plate 222 , so that the annular winding plate 222 can wind or release the data cable 3 and the flat cable 4 at the same time.

[0081] In some embodiments, Figure 2 and Figure 3 As shown, the annular winding plate 222 is formed with a notch 223 , and the connecting end of the data line 3 is passed through the notch 223 and connected to one end of the flat cable 4 , or one end of the flat cable 4 is passed through the notch 223 and connected to the connecting end of the data line 3 .

[0082] It can be understood that, by providing the notch 223 , the connection end of the data cable 3 and one end of the flat cable 4 can be connected through the notch 223 .

[0083] Finally, it should be noted that the above implementation modes are only used to illustrate the present application, rather than to limit the present application. Although the present application is described in detail with reference to the embodiments, a person skilled in the art should understand that various combinations, modifications or equivalent substitutions of the technical solutions of the present application do not depart from the spirit and scope of the technical solutions of the present application, and should be included in the scope of the claims of the present application.
