The present application can be implemented in other ways. Moreover, it should be understood that the terms and phrases used herein are only for descriptive purposes and should not be construed restrictively. The terms "including", "comprising", "having" and the like used herein are intended to include the matters listed hereinafter, their equivalents and other additional matters. In particular, when describing "a certain element", the present application does not limit the number of such elements to one, and multiple elements can also be included.

[0030] Please refer to Figures 1 to 7 As shown, the present application provides a charger 10, which can be used to charge electronic devices such as mobile phones and tablet computers. The charger 10 includes a housing 12, a charging module 14, a drawstring module 16 and a pin module 18. An installation cavity 20 is formed in the housing 12.

Among them, the charging module 14 and the drawstring module 16 are stacked along the first direction a. By modularizing the internal components of the charger 10 according to their functions first and then modularly assembling each module on the housing 12, the present application has a small stacking volume, reduces the overall volume of the charger 10, greatly reduces the assembly difficulty, simplifies the assembly process flow, increases the assembly efficiency of the product, and is convenient for disassembly and maintenance. It should be noted that the modules in the drawstring module 16, the pin module 18 and the charging module 14 are understood as functional modules that can be assembled into the housing 12 without further assembling the internal components. When a component in the module fails, the entire module can be removed and replaced.

[0031] Further, the pin module 18, the charging module 14, and the pull wire module 16 are arranged along the second direction b, and the second direction b is perpendicular to the first direction a. The arrangement of the pin module 18, the charging module 14, and the pull wire module 16 along the second direction b allows the charging module 18 and the pull wire module 16 to be installed in the housing 12 along the first direction a, and then the pin module can be fixed in the second direction b within the housing 12, facilitating the installation and fixation of the pin module 14. Moreover, when installing the charging module 14 and the pull wire module 16, a space for assembling the pin module 14 is reserved in the second direction b within the housing 12. The pull wire module 16 needs to pull one end of the charging wire 48 out of the housing 12. The reserved space facilitates assembly, reduces the assembly difficulty. At the same time, the modules are stacked in this way, and the module assembly is compact, reducing the volume of the charger 10.

[0032] In this embodiment, the housing 12 is generally rectangular parallelepiped-shaped. In other embodiments, the housing 12 can also be designed in other shapes. The housing 12 has mutually perpendicular length, width, and thickness directions. Preferably, the above-mentioned first direction a is, for example, the thickness direction of the housing 12, and the second direction b is, for example, the length direction of the housing 12. In addition, the housing 12 also has a third direction c. In this embodiment, the third direction c is, for example, the width direction of the housing 12. Therefore, the first direction a, the second direction b, and the third direction c are mutually perpendicular.

The two second solder joints 34 are located on one side of the pin module 18 in the first direction a, so that the plurality of second solder joints 34 are exposed for easy soldering. The charging module 14 is welded to the 5 first solder joints 30 and the 2 second solder joints 34 respectively through a plurality of wires one by one, so as to realize the electrical connection between the drawstring module 16 and the pin module 18 and the charging module 14 respectively. The method of electrical connection through wires facilitates the assembly and installation between each module, enables the plurality of modules to be compactly installed, reduces the occupied volume, and the electrical connection is more stable.

[0035] In such as Figures 2 - 3In the illustrated embodiment, a bracket 44 is provided in the installation cavity 20. The bracket 44 is located between the draw wire module 16 and the charging module 14 and is used to fix the draw wire module 16 to the bottom case 24. An installation position 46 is provided on a side of the bracket 44 facing away from the charging module 14. The draw wire module 16 is fixedly installed at the installation position 46, for example, by means of pasting or the like.

Among them, two first positioning and fixing portions 40 and two second positioning and fixing portions 42 may be respectively provided. The two first positioning and fixing portions 40 are provided on opposite sides of the bracket 44, and the positions of the two second positioning and fixing portions 42 respectively correspond to the positions of the two first positioning and fixing portions 40 one by one. Preferably, a positioning groove is provided at the bottom of the first positioning and fixing portion 40, and a positioning post is provided at the top of the second positioning and fixing portion 42. The positioning post and the positioning groove are in positioning cooperation, so as to realize the installation positioning of the bracket 44 and the draw wire module 16; after positioning, the first positioning and fixing portion 40 and the second positioning and fixing portion 42 are locked by screws, so as to fix the bracket 44 and the draw wire module 16 relative to the housing 12.

[0036] In the embodiment as Figure 7 shown, the bracket 44 is not provided. The draw wire module 16 includes an outer cover 38. A first positioning and fixing portion 40 is provided around the outer cover 38. The first positioning and fixing portion 40 and the outer cover 38 may be an integrally formed structure. A second positioning and fixing portion 42 is provided in the installation cavity 20. The second positioning and fixing portion 42 is provided, for example, on the bottom wall of the bottom case 24. The first positioning and fixing portion 40 and the second positioning and fixing portion 42 are in positioning cooperation and fixedly connected. Among them, two first positioning and fixing portions 40 and two second positioning and fixing portions 42 may be respectively provided. The two first positioning and fixing portions 40 are provided on opposite sides of the outer cover 38, and the positions of the two second positioning and fixing portions 42 respectively correspond to the positions of the two first positioning and fixing portions 40 one by one. Preferably, a positioning groove is provided at the bottom of the first positioning and fixing portion 40, and a positioning post is provided at the top of the second positioning and fixing portion 42. The positioning post and the positioning groove are in positioning cooperation, so as to realize the installation positioning of the draw wire module 16; after positioning, the first positioning and fixing portion 40 and the second positioning and fixing portion 42 are locked by screws, so as to fix the draw wire module 16 relative to the housing 12.

[0037] More specifically, the draw wire module 16 further includes a charging wire 48. A wire winding position is formed inside the outer cover 38. One end of the charging wire 48 is wound around the wire winding position, and the other end is telescopically inserted through the outer cover 38 and the bottom shell 24. And an elastic reset member is provided in the wire winding position. The elastic reset member is, for example, a clockwork spring. The elastic reset member applies an elastic biasing force to the charging wire 48 to make it wind into the wire winding position, so that after the charging wire 48 is pulled out and used up, it can automatically reset under the elastic force of the elastic reset member. Furthermore, when the charging wire 48 is not in use, it can be automatically wound and stored in the wire winding position. Wherein, a first wire outlet 50 is provided on the side wall of the outer cover 38, and a second wire outlet 52 corresponding to the first wire outlet 50 is provided on the side wall of the bottom shell 24. The second wire outlet 52 is, for example, provided on the side of the bottom shell 24 facing away from the plug module 18. The draw end of the charging wire 48 is telescopically inserted through the first wire outlet 50 and the second wire outlet 52.

[0038] Preferably, a charging connector 54 is provided at one end of the charging wire 48 outside the housing 12. A storage portion 56 for storing the charging connector 54 is provided on the side wall of the bottom shell 24. The storage portion 56 is, for example, a groove structure. The second wire outlet 52 is provided at one end of the bottom of the storage portion 56. To facilitate the installation of the draw wire module 16, the size of the second wire outlet 52 is larger than the size of the charging connector 54, so that the charging connector 54 can pass through the second wire outlet 52 from the installation cavity 20. Further, a sleeve plug 58 is also sleeved on the charging wire 48. The sleeve plug 58 is detachably installed on the second wire outlet 52. For example, the sleeve plug 58 is fixed to the second wire outlet 52 by a snap-fit method. A first snap portion is provided on the inner wall of the second wire outlet 52, and a second snap portion is correspondingly provided on the side edge of the sleeve plug 58. The first snap portion and the second snap portion are snap-fitted. For example, a step is also provided around the sleeve plug 58, so that the sleeve plug 58 is fixed inside the second wire outlet 52 by the step. The size of the second wire outlet 52 is large, and dust is likely to enter the installation cavity 20.

[0039] To facilitate the fixation of the charging connector 54 in the storage portion 56, the charging connector 54 is provided with a first magnetic member (not shown in the figure). For example, it is hidden inside the charging connector 54. The storage portion 56 is provided with a second magnetic member 60. The second magnetic member 60 is, for example, provided on the inner side wall of the installation cavity 20 near the storage portion 56. An installation position 62 can be provided on the inner side of the side wall of the bottom shell 24 corresponding to the storage portion 56. The second magnetic member 60 is fixedly installed in the installation position 62. The first magnetic member and the second magnetic member 60 are magnetically coupled, so that the charging connector 54 can be stored and fixed in the storage portion 56 by magnetic attraction.

[0040] In the illustrated embodiment, the charging module 14 includes a circuit board 64, a transformer 66, and a plurality of capacitors 68 disposed on the circuit board 64. Among them, the transformer 66 and the plurality of capacitors 68 are arranged on one side of the circuit board 64 close to the cover 22. Since it is difficult to adjust the height of the transformer 66 in the first direction a, while the height of the capacitor 68 is easy to adjust, a plurality of capacitors 68 can be arranged to extend along the first direction a, and the height of the capacitor 68 in the first direction a is less than or equal to the height of the transformer 66 in the first direction a. Such an arrangement can facilitate the layout design of the capacitor 68 on the one hand, and on the other hand, can reduce the height of the charging module 14, thereby reducing the overall thickness and volume of the charger 10.

[0041] Further, a third positioning and fixing portion 70 is provided on the periphery of the circuit board 64, and a fourth positioning and fixing portion 72 is provided in the installation cavity 20. The fourth positioning and fixing portion 72 is, for example, provided on the bottom wall of the bottom case 24. The third positioning and fixing portion 70 and the fourth positioning and fixing portion 72 are in positioning cooperation and fixedly connected. Among them, two third positioning and fixing portions 70 can be provided, and the two third positioning and fixing portions 70 are arranged at opposite corner portions of the circuit board 64. The third positioning and fixing portion 70 is, for example, a fixing hole; correspondingly, two fourth positioning and fixing portions 72 are also provided, and the positions of the two fourth positioning and fixing portions 72 correspond to the positions of the two third positioning and fixing portions 70 one by one. The fourth positioning and fixing portion 72 is, for example, a fixing post. During installation, the third positioning and fixing portion 70 and the fourth positioning and fixing portion 72 are first positioned and then fixed by screws to realize the positioning and fixing installation of the charging module 14. Preferably, a charging interface 74 is further provided on the side wall of the bottom case 24, and the charging interface 74 is electrically connected to the circuit board 64. The charging interface 74 is, for example, provided on the same side wall of the bottom case 24 as the storage portion 56.

[0042] Preferably, a plurality of support ribs 76 are provided on the side wall of the installation cavity 20. The plurality of support ribs 76 are arranged circumferentially along the inner side wall of the bottom case 24. The support ribs 76 are used to support the charging module 14 and the draw wire module 16. For example, the top platforms of the support ribs 76 support the bottom of the circuit board 64 and the bottom of the outer cover 38, further enhancing the stability of the charging module 14 and the draw wire module 16.

[0043] In the illustrated embodiment, the plug module 18 includes a connection base 78 and a plug 80 that can rotate relative to the connection base 78. A rotation groove 82 is provided on the side wall of the bottom case 24, and the plug 80 is rotatably installed in the rotation groove 82. The rotation groove 82 and the storage portion 56 are respectively located on opposite side walls of the bottom case 24. The plug 80 can rotate between a folded position and an extended position. When in the extended position, the plug 80 extends out of the rotation groove 82 and can be used to plug into an external power socket to achieve electrical connection. When in the folded position, the plug 80 is received in the rotation groove 82. In the present application, the plug 80 shown in the drawings is in the folded position.

[0044] The fifth positioning and fixing part 84 is arranged in the installation cavity 20. For example, the fifth positioning and fixing part 84 is arranged at the connection part of the bottom wall and the side wall of the bottom shell 24. The sixth positioning and fixing part 86 is arranged at the edge of the connection seat 78. The sixth positioning and fixing part 86 is located in the third direction c of the connection seat 78. The fifth positioning and fixing part 84 is in positioning cooperation with the sixth positioning and fixing part 86 and is fixedly connected. Among them, the fifth positioning and fixing part 84 is, for example, a fixing column, and the sixth positioning and fixing part 86 is, for example, a connection hole. During installation, the fifth positioning and fixing part 84 and the sixth positioning and fixing part 86 are first positioned and then fixed by screws, so as to realize the positioning installation and fixation of the pin module 18. In this embodiment, the sixth positioning and fixing part 86 protrudes from the side peripheral edge of the connection seat 78, so that when the connection seat 78 is installed in the installation cavity 20, the sixth positioning and fixing part 86 is located in the width direction of the bottom shell 24, and the length of the outer shell 12 can be reduced; and since the size of the pin module 18 is smaller than that of the charging module 14 and / or the draw wire module 16, after the connection seat 78 is installed in the installation cavity 20, in the width direction of the bottom shell 24 of the installation cavity 20, there are vacant positions between adjacent connection seats 78, and the sixth positioning and fixing part 86 located in the width direction of the bottom shell 24 can just be located in the vacant positions, so that the overall volume of the charger 10 is reduced.

[0045] Preferably, a limiting part 88 and a support member 90 are further arranged in the installation cavity 20. The limiting part 88 is, for example, arranged on the side wall of the bottom shell 24 in the width direction adjacent to the rotation groove 82. The limiting part 88 is, for example, a block structure. The limiting part 88 and the fifth positioning and fixing part 84 are located outside the opposite ends of the rotation groove 82 in the length direction, and a limiting space is formed between the limiting part 88, the fifth positioning and fixing part 84 and the side wall of the bottom shell 24 to limit the connection seat 78 in the second direction b and the third direction c. The support member 90, for example, includes two plate-like structures arranged at intervals in the third direction c. The support member 90 is arranged at the corner part where the side wall and the bottom wall of the bottom shell 24 are connected and is located below the rotation groove 82. The support member 90 is used to support the connection seat 78 to limit the connection seat 78 in the first direction a. The limiting part 88, the support member 90, and the fifth positioning and fixing part 84 are arranged around the rotation groove 82, and cooperate with the side wall of the bottom shell 24 to limit the connection seat 78, so that when assembling, the connection part between the pin 80 and the connection seat 78 is aligned, and the pin 80 can be directly installed on the connection seat 78 in a position-aligned manner, simplifying the assembly process flow. Preferably, a rotation mounting seat 92 is arranged on the inner wall of the bottom shell 24 on one side of the rotation groove 82. During installation, the rotation part of the pin 80 can be rotatably installed on the rotation mounting seat 92.

[0046] When assembling the charger 10, first take out the bottom case 24, position and place the drawstring module 16 into the installation cavity 20. Then, pull the charging cable 48 to pass the charging connector 54 outwards from the inside through the second wire outlet 52 and magnetically store it in the storage part 56. Fix the sleeve plug 58 and use screws to lock the drawstring module 16. Since the bottom case 24 has a large operating space in the length direction, and the charging connector 54 and the drawstring module 16 are distributed in the length direction of the bottom case 24, the drawstring module 16 can be easily assembled on the bottom case 24. Weld the multiple wires of the charging module 14 to the solder joints on the drawstring module 16 and the pin module 18 respectively, and then position and place the charging module 14 into the installation cavity 20 and lock it with screws. Since the solder joints of the pin module 18 and the solder joints of the drawstring module 16 are both distributed in the length direction of the bottom case 24, and the size of the bottom case in the length direction is large, the welding operation is easy to perform. Install the pins 80 outwards from the installation cavity 20 by aligning them with the rotation slots 82 and fix them on the rotary mounting base 92. Align the connecting seat 78 and move it downwards from top to bottom until it abuts against the support member 90 and lock it with screws. The remaining space in the installation cavity 20 is just enough for the connecting seat 78 to be inserted along the thickness direction of the bottom case 24, and the solder joints of the pin module 18 are arranged close to the cover body 22 side, so that the welding operation is easy to perform. Finally, cover the cover body 22 on the bottom case 24, and the assembly is completed. The charger 10 is installed compactly and the assembly process is simple.
