Description

Technical Field

[0001] This application relates to the technical field of accessories for electronic devices, and particularly to a charger. Background Art

[0002] With the rapid development of technology in recent years, electronic devices have become one of the essential devices in modern people's lives. For example, people often carry electronic devices such as mobile phones, tablets, and cameras when traveling. The functions of these electronic devices rely on sufficient power. As an accessory for charging electronic devices, chargers have gradually become an essential item in people's work and life. Even when users go out, they will carry chargers with them to achieve the purpose of connecting to a power source at any time to charge electronic devices.

[0003] Existing chargers generally include a charging main body and a charging cable connected to the charging main body. This structural form is prone to charging cable entanglement and affects aesthetics. In response to this, some people have proposed to wind the charging cable retractably inside the charging main body to achieve the storage of the charging cable. However, for such a charger with a retractable charging cable, it is obviously not suitable if the outer shell of the charging main body still adopts the traditional assembly method of docking two shell parts. Since a drawstring module needs to be arranged inside the charging main body and the corresponding structure for the retraction of the charging cable needs to be considered, the traditional assembly method will lead to difficulties in assembling the outer shell of the charging main body.

[0004] Based on this, it is necessary to improve the existing charger to solve the above problems. Summary of the Invention

[0022] Before describing the embodiments in detail, it should be understood that the present application is not limited to the detailed structures or element arrangements described in the following text or drawings of the present application. 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 as limiting. The terms "including", "comprising", "having" and the like used herein are intended to include the matters listed thereafter, 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.

[0023] Please refer to Figures 1 to 4As shown in the figure, 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, and a drawstring module 16. Among them, the housing 12 includes a first housing portion 18 and a second housing portion 20 that are oppositely arranged in the first direction a, and a third housing portion 22 and a fourth housing portion 24 that are oppositely arranged in the second direction b. The first housing portion 18, the second housing portion 20, the third housing portion 22, and the fourth housing portion 24 jointly enclose a cavity 26. The charging module 14 and the drawstring module 16 are installed in the cavity 26, and the charging module 14 is electrically connected to the drawstring module 16. By splitting the housing 12 into four parts, the present application not only enables each component of the charger 10 to be individually installed in the corresponding housing portion, reducing the installation difficulty, but also greatly simplifies the assembly of the housing 12, thereby simplifying the assembly process flow.

[0024] 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 a length direction, a width direction, and a thickness direction that are perpendicular to each other. Preferably, the above-mentioned first direction a is the thickness direction of the housing 12, and the second direction b is the length direction of the housing 12. Optionally, the housing 12 further has a third direction c. In this embodiment, the third direction c is the width direction of the housing 12. Therefore, the first direction a, the second direction b, and the third direction c are perpendicular to each other. At least one end of the third housing portion 22 and the fourth housing portion 24 at both ends in the third direction c is provided with an arc portion 28. For example, both ends of the third housing portion 22 and the fourth housing portion 24 are bent toward the cavity 26 side to form the arc portion 28. By providing the arc portion 28, the volume of the charger 10 can be reduced. For example, if the drawstring module 14 is cylindrical, setting the arc portion 28 in the third direction c on the third housing portion 22 and the fourth housing portion 24 can make the shape of the housing 12 of the charger 10 match the shape of the drawstring module 14. The housing 12, the drawstring module 14, and related components are compactly arranged, reducing the volume of the charger 10 and improving the aesthetic appearance at the same time.

[0025] More specifically, the drawstring module 14 includes a charging wire (not shown in the figure) that is telescopically disposed through the third housing portion 22. One end of the charging wire outside the third housing portion 22 is provided with a charging connector 30, and the charging connector 30 is used to connect to an electronic device to charge it. A storage position 32 for storing the charging connector 30 is provided on the outer wall of the third housing portion 22. The storage position 32 is, for example, a groove structure. A through port communicating with the cavity 26 is provided on the inner wall of the storage position 32, and the charging wire is telescopically disposed through the through port. If the housing adopts the traditional connection method of docking two housing portions, the storage position 32 needs to be divided into two parts and separately provided on the two housing portions, increasing the process difficulty. In the present application, the storage position 32 can be separately provided on the third housing portion 22, simplifying the process flow.

[0026] Further, the first housing portion 18 is butt-joined to the second housing portion 20, and a first mounting opening 36 and a second mounting opening 38 are respectively formed at both ends in the second direction b.
