In particular, when describing "a certain element", the present application does not limit the number of the element to one, but may also include multiple elements.

[0025] Please also refer to Figures 1 to 7 As shown, the present application provides a charger 10 that can be used to charge electronic devices such as mobile phones and tablets. The charger 10 includes a shell 12 and a charging module 13, a bracket 16, and a telescopic wire module 38 arranged in the shell 12. The bracket 16 is connected and fixed to the shell 16. The charging module 13 and the telescopic wire module 38 are arranged on opposite sides of the bracket 16. The bracket 16 is provided with a clamping position 18, and the charging module 13 is clamped in the clamping position 18. The present application abandons the method of fixing the charging circuit board with screws in the prior art, and fixes the charging module 13 to the bracket 16 by means of a buckle. There is no need to open a screw position on the charging module 13, so as to avoid the screw position occupying the area of the charging module 13, thereby reducing the area of the charging module 13 and reducing the size of the charging module 13 in the length or width direction, thereby reducing the overall volume of the charger 10.

[0026] In the embodiment shown, the housing 12 is in the shape of a rectangular parallelepiped as a whole. In other embodiments, the housing 12 can also be designed into other shapes. The housing 12 has a length direction a, a width direction b, and a thickness direction c. The length direction a, the width direction b, and the thickness direction c are perpendicular to each other. The charging module 13 and the bracket 16 are stacked in the thickness direction c. The housing 12 includes an upper shell 20 and a lower shell 22 that are butt-jointed in the thickness direction c, and a first side shell 24 and a second side shell 26 connected at both ends of the length direction of the upper shell 20 and the lower shell 22. The upper shell 20 and the lower shell 22 are connected and fixed by means of, for example, snaps, etc., and the first side shell 24 and the second side shell 26 are connected and fixed at both ends of the upper shell 20 and the lower shell 22 by means of, for example, snaps, etc.

[0028] Preferably, a plurality of first hooks 28 are protruding from one side of the bracket 16 close to the charging circuit board 14, and a holding position 18 is formed between the plurality of first hooks 28. The first hooks 28 are arranged on the periphery of the bracket 16, and the hook portion of the first hook 28 is arranged toward the middle area of the charging circuit board 14. It should be noted that when the charging circuit board 14 is a polygon, the middle area includes the middle position of a certain edge of the charging circuit board 14. For example, when the charging circuit board 14 is a rectangle, the middle area includes the middle section of one side of the rectangle. In this embodiment, three hooks 28 are provided, of which two hooks 28 are provided on one side in the length direction of the bracket 16, and the other hook 28 is provided on the other side in the length direction of the bracket 16. In other embodiments, the hooks 28 may also be provided in other numbers, which is not limited in this application. Optionally, the hooks 28 are provided toward one side of the charging circuit board 14, that is, the hooks 28 are provided toward the upper shell 20. When the charging circuit board 14 is locked in the locking position 18 , the hook portion of the locking hook 28 is hooked on the peripheral edge of the charging circuit board 14 facing away from the bracket 16 , so as to lock and fix the charging circuit board 14 .

[0029] The bracket 16 is connected and fixed to the housing 12. Specifically, the housing 12 is provided with a first locating member 30, and the bracket 16 is provided with a second locating member 32. The first locating member 30 and the second locating member 32 are positioned and cooperated, so that the bracket 16 can be installed and fixed according to a predetermined orientation and predetermined position. Preferably, the first locating member 30 is one of a first locating post and a first locating hole, and the second locating member 32 is the other of the first locating post and the first locating hole. The second locating member 32 is provided on the side of the bracket 16 facing away from the charging circuit board 14. In the illustrated embodiment, the first locating member 30 is a first locating hole, and the second locating member 32 is a first locating post. The first locating post and the first locating hole are positioned and plugged together. The first locating post is, for example, provided at a peripheral position on the side of the bracket 16 facing away from the charging circuit board 14, and the first locating hole is provided on the inner bottom wall of the lower shell portion 22. For example, the inner bottom wall of the lower shell portion 22 is provided with a columnar structure, and the first locating hole is provided on the top wall of the columnar structure. A plurality of first positioning posts and a plurality of first positioning holes may be provided respectively. The plurality of first positioning posts are spaced apart along the circumference of the bracket 16 , and the positions of the first positioning holes correspond one-to-one to the first positioning posts.

[0030] Furthermore, the bracket 16 is removably connected and fixed to the housing 12 to facilitate assembly, disassembly, and maintenance. Specifically, the housing 12 is provided with a first connector 34, and the bracket 16 is provided with a second connector 36. The first connector 34 and the second connector 36 are removably connected. Preferably, the first connector 34 and the second connector 36 are snap-fitted. The first connector 34 is either a second hook or a slot, and the second connector 36 is either a second hook or a slot.

In the illustrated embodiment, the first connector 34 is a slot, and the second connector 36 is a second hook. The second hook and the slot are snap-fitted. The slot is defined by a structural wall on the inner bottom wall of the lower housing portion 22. The second hook is protruding from the periphery of the bracket 16, with the hook portion of the second hook facing the housing 12. Multiple second hooks and slots can be provided, respectively. Multiple second hooks are spaced apart along the circumference of the bracket 16, with the slots corresponding to the hooks. In the prior art, bracket 16 is fixed to housing 12 by screws, which requires opening screw holes in bracket 16 and adding screw welding locations. After the screws are installed, they occupy thickness space and increase the volume of the product. The present application avoids the traditional screw fixing method by connecting bracket 16 to housing 12 through a snap-fit method. This avoids opening screw holes in bracket 16 and adding screw welding locations, thereby reducing the thickness and overall volume of the product.

[0031] In the illustrated embodiment, the charger 10 includes a retractable wire module 38 disposed on the side of the bracket 16 facing away from the charging circuit board 14. The retractable wire module 38 is, for example, circular in shape as a whole and electrically connected to the charging circuit board 14. The retractable wire module 38 includes a charging wire (not shown), which is movably inserted into the housing 12. The charging circuit board 14 is for high-voltage power, while the retractable wire module 38 is for low-voltage power. The bracket 16 disposed between the charging circuit board 14 and the retractable wire module 38 can isolate high-voltage power from low-voltage power. The prior art uses screws to connect the bracket 16 and the housing 12. Since screws are conductive, it is difficult to isolate high-voltage power from low-voltage power. The present application connects the bracket 16 and the housing 12 by snapping, so that the bracket 16 can achieve a good isolation effect between high-voltage power and low-voltage power.

[0032] Specifically, the telescopic line module 38 includes a fixed circuit board 40, a rotating circuit board 42 and a rotating seat 44. The fixed circuit board 40 is fixed to the side of the bracket 16 away from the charging circuit board 14 and is electrically connected to the charging circuit board 14. The fixed circuit board 40 and the bracket 16 are fixed, for example, by bonding or snapping. The rotating circuit board 42 is located between the fixed circuit board 40 and the rotating seat 44 and is fixedly connected to the rotating seat 44. The rotating circuit board 42 is electrically connected to the fixed circuit board 40. The charging line can be movably wrapped around the rotating seat 44 and electrically connected to the rotating circuit board 42. The rotating seat 44 is fixedly connected to the housing 12, for example, by snapping.

[0033] Preferably, a second positioning post 80 is provided on the side of the bracket 16 near the charging circuit board 14, and a second positioning hole 82 is provided on the charging circuit board 14 to match the second positioning post 80. Multiple second positioning posts 80 and second positioning holes 82 may be provided. During installation, the charging circuit board 14 is positioned and installed on the bracket 16 through the positioning and cooperation between the second positioning post 80 and the second positioning hole 82. The fixed circuit board 40 is provided on the bracket 16, and a third positioning post 84 is provided on the bracket 16 near the fixed circuit board 40. The fixed circuit board 40 is provided with a third positioning hole 86 that matches the third positioning post 84. Multiple third positioning posts 84 and third positioning holes 86 may be provided. During installation, the fixed circuit board 40 is positioned and installed on the bracket 16 through the positioning and cooperation between the third positioning post 84 and the third positioning hole 86.

[0034] In the illustrated embodiment, a fixed shaft 46 is provided in the center of the bracket 16 on the side facing away from the charging circuit board 14. The retractable cable module 38 includes a rotating module, namely, a rotating circuit board 42 and a rotating base 44. The fixed shaft 46 is inserted through the fixed circuit board 40, and the rotating module is rotatably mounted on the outside of the fixed shaft 46. Specifically, the fixed shaft 46 is inserted through the fixed circuit board 40 and the rotating circuit board 42, and the rotating base 44 is rotatably mounted on the outside of the fixed shaft 46. The rotating base 44 includes a base plate 48 and a rotating disk 50 protruding from the center of the base plate 48. The rotating circuit board 42 is fixed to the rotating disk 50 and, together with the rotating disk 50 and base plate 48, forms a winding space 52 for the charging cable. The turntable 50 is provided with a protrusion 54 and a limiting protrusion 56. The protrusion 54 is provided through the rotating circuit board 42 and protrudes outside the rotating circuit board 42. The protrusion 54 provides a reinforcement effect. When the charging cable is pulled to the end, the reinforcement effect of the protrusion 54 can effectively prevent the housing 12 from cracking. The limiting protrusion 56 is provided through the rotating circuit board 42 and protrudes outside the rotating circuit board 42. The limiting effect of the limiting protrusion 56 can prevent the charging cable from moving out of its initial position after being pulled to the end. Among them, one or more protrusions 54 and limiting protrusions 56 can be provided. The protrusion 54 extends along the circumference of the turntable 50, and multiple limiting protrusions 56 are arranged at intervals along the circumference.

[0035] Furthermore, a guide track 58 is provided on the side of the fixed circuit board 40 facing the rotating circuit board 42, and an elastic guide member 60 is provided on the side of the rotating circuit board 42 facing the fixed circuit board 40. The elastic guide member 60 slidably engages with the guide track 58. One end of the charging cable is wrapped around the rotating base 44, and the other end is inserted outside the housing 12. When the charging cable is pulled, the rotating base 44 rotates, which in turn rotates the rotating circuit board 42. The sliding engagement between the elastic guide member 60 and the guide track 58 ensures that the rotating circuit board 42 remains electrically connected to the fixed circuit board 40 during rotation. The end of the charging cable located within the housing 12 is electrically connected to the rotating circuit board 42, for example, by welding. The end of the charging cable located outside the housing 12 is provided with a charging connector 62, which is retractably inserted through the first side housing 24. A storage area 64 for accommodating the charging connector 62 is provided on the outer surface of the first side housing 24, for example, a recessed structure. An elastic return member (not shown) is provided within the turntable 50. Such a member, for example, a spring, is used to apply an elastic bias to the turntable 50, causing it to rotate toward its initial position. This allows the rotating base 44 to automatically return to its original position after rotation, allowing the charging cable to be automatically wound around the turntable 50 for storage when not in use. The fixed circuit board 40 is provided with a conductive terminal 66. This conductive terminal 66 extends through the bracket 16 and is electrically connected to the charging circuit board 14. The conductive terminal 66 is, for example, located on the side of the fixed circuit board 40.

[0036] In the illustrated embodiment, the charger 10 includes a charging plug 68, which is disposed on the housing 12 and electrically connected to the charging circuit board 14. The charging plug 68 is used to connect to an external power source. The charging plug 68 is, for example, disposed on a side of the housing 12 opposite to the storage position 64, that is, the charging plug 68 is disposed on the second side shell 26. The charging plug 68 can be configured to be foldably mounted on the second side shell 26, rotated open when needed, and folded and stored when not in use.

[0037] In summary, the present application provides a charger comprising a housing and a charging module, a retractable wire module, and a bracket disposed within the housing. The bracket is fixedly connected to the housing, and the charging module and the retractable wire module are disposed on opposite sides of the bracket. The bracket is provided with a retaining position, and the charging module is retained in the retaining position. The present application abandons the prior art method of fixing the charging circuit board with screws, and fixes the charging module to the bracket by means of a snap. There is no need to provide screw positions on the charging module, which prevents the screw positions from occupying the area of the charging module, thereby reducing the area of the charging module, reducing the length or width dimensions of the charging module, and thereby reducing the overall volume of the charger.

[0038] The concepts described herein may be embodied in other forms without departing from their spirit and characteristics. The specific embodiments disclosed are to be considered illustrative rather than restrictive.
