Description

Technical Field

[0001] This utility model relates to the field of charging device technology, and in particular to a charger with a retractable cord. Background Technology

[0002] To enhance convenience and comfort in daily life, numerous electronic products have emerged. These products consume power during use, requiring chargers. Currently, there are various types of chargers available, including those with retractable cords. A retractable cord charger includes a main body, a terminal block within the main body that connects to a power source, and a charging interface (e.g., USB Type-C, Lightning) for connecting to the electronic product. The charging interface uses either an NG or Micro-USB interface. It includes a male connector for connecting to the electronic device and a support for the male connector (the male connector is used to connect to the socket of the electronic device to charge it), and a retractable cable that connects the electrical terminals to the charging interface. The retractable cable is wound on a reel inside the charger. When the charging interface is unplugged, the retractable cable unwinds from the reel inside the charger. When the charging interface is released, the retractable cable retracts via a retraction mechanism on the reel, automatically returning to the charger body. When not in use, the retractable cable can be completely stored inside the charger body, saving space and making it convenient for users to use and carry. However, for aesthetic reasons, the charging interface is usually hidden in a recessed slot within the charger body. But every time the charging interface is needed to charge an electronic device, it must be pried out of the slot with a finger, making it difficult to remove and resulting in a poor user experience.

[0047] Please see Figure 1-4 In one embodiment of this utility model, a charger with a retractable cable includes a body 10, a data cable, and an interface storage part 20. The body 10 has a storage space 11. The data cable includes a cable body 40 and a charging interface 30 disposed at the end of the cable body 40. The interface storage part 20 is disposed on one side wall of the body 10. The interface storage part 20 includes two guide side walls 21, a guide surface 22 disposed between the two guide side walls 21, and a stop surface 23 located at one end of the guide side wall 21. The two guide side walls 21 are parallel to each other and spaced apart. Figure 2 Only one guide sidewall 21 is shown, and the other guide sidewall 21 is provided on the opposite side of the guide sidewall 21 shown. The guide sidewall 21, the guide surface 22, and the stop surface 23 form a sliding groove 222. It can be understood that the sliding groove 222 of this application is formed by the sidewall of the body recessed in the interface receiving part 20.

[0048] The sliding groove 222 has a cable outlet 230 at one end near the abutment surface 23, and the cable outlet 230 communicates with the storage space 11. The storage space 11 contains a cable reel 110. The end of the cable 40 away from the charging interface 30 is wound around the cable reel 110. The cable retraction is achieved by rotating the cable reel 110. The end of the cable 40 near the charging interface 30 passes through the cable outlet 230, and the charging interface 30 is housed within the sliding groove 222. The guide surface 22 includes a sliding surface 220 and a sliding surface 221 inclined relative to the sliding surface 220. The sliding surface 220 is connected to the abutment surface 23, and the sliding surface 221 is located on the side of the sliding surface 220 away from the abutment surface 23. When the charging interface 30 is housed within the sliding groove 222, the end of the charging interface 30 connected to the cable 40 can contact or abut against the abutment surface 23 (e.g., ...). Figure 3 (As shown).

[0049] In the above technical solution of this application, when the charging interface 30 is not used, the charging interface 30 is stored in the sliding groove 222. When the charging interface 30 needs to be used, the charging interface 30 is moved to slide along the sliding surface 220 under the guidance of the two guide side walls 21 until it slides to the sliding lifting surface 221. After the charging interface 30 is lifted by the sliding lifting surface 221, the charging interface 30 protrudes out of the body 10, making it easy to remove. When the charging interface 30 is stored in the sliding groove 222, the end of the charging interface 30 connected to the cable 40 can abut against the stop surface 23, which can make the length of the sliding surface 220 as small as possible, reduce the volume of the sliding groove 222, and make the charger look more beautiful.

[0050] Please see Figure 1-4In one embodiment of this utility model, the sliding surface 221 extends obliquely relative to the sliding surface 220 in a direction away from the stop surface 23 and closer to the opening of the sliding groove 222, and the angle between the sliding surface 221 and the sliding surface 220 is 150 degrees to 175 degrees. The charging interface 30 includes a support body 32 and a male connector 31 disposed at one end of the support body 32. One end of the support body 32 is connected to the cable 40, and the other end is connected to the male connector 31. If the angle range is less than 150°, the male connector 31 of the charging interface 30 will interfere with the sliding surface 221. If the angle range is greater than 175°, the sliding surface 221 is too flat, and there is no good lifting trend when the support body 32 is moved, making it inconvenient to remove the charging interface 30.

[0051] Furthermore, the charging interface 30 includes a support body 32 and a male connector 31. One end of the support body 32 is connected to the cable 40, and the other end is connected to the male connector 31. When the charging interface 30 is housed within the sliding groove 222, the sliding surface 220 is connected to the support body 32, and at least part of the male connector 31 is located above the sliding surface 221. When the charging interface 30 is not in use, the side of the support body 32 away from the male connector 31 rests against the stop surface 23. In the charging interface 30, the support body 32 rests on the sliding surface 220, while the male connector 31 of the charging interface 30 rests above the sliding surface 221 (e.g., ...). Figure 3 (As shown); This positioning allows for minimizing the sliding tilting stroke of the support 32, which in turn controls the toggle removal stroke of the charging interface 30. The charging interface 30 is removed after the support 32 slides and tilts during the minimum toggle stroke.

[0052] For further details, please refer to Figure 1-4 In one embodiment of this utility model, the length of the sliding surface 221 is 10mm to 13mm. The sliding length of the sliding surface 221 is 10mm to 13mm. With the setting of the tilt angle of the sliding surface 221, the male connector 31 of the charging interface 30 does not interfere with the sliding surface 221, and the support 32 of the charging interface 30 has a certain sliding stroke on the sliding surface 221. At the same time, the volume of the charging device body 10 will not increase due to excessive sliding stroke.

[0053] Please see Figure 1-4In one embodiment of this utility model, the sliding surface 221 is a planar or arc-shaped surface. The sliding surface 220 is planar, and the sliding surface 221 can be planar or arc-shaped. In this embodiment, an arc-shaped surface is preferred. The arc-shaped surface easily avoids interference with the male connector 31 in front of the charging interface 30, and at the same time, it has a good lifting effect on the support 32, making it easier to remove the charging interface 30. It should be noted that the angle between the sliding surface 220 and the sliding surface 221 is the angle formed between the planar and the arc-shaped surface. More specifically, it is the angle formed between the virtual plane 2210 formed by the planar and the arc-shaped surface. The virtual plane 2210 formed by the arc-shaped surface passes through two straight lines. The first straight line 2211 passes through the starting end of the arc-shaped surface and is parallel to the axis of the arc-shaped surface. The second straight line 2212 passes through the ending end of the arc-shaped surface and is parallel to the axis of the arc-shaped surface. The aforementioned virtual plane 2210 coincides with the first straight line 2211 and the second straight line 2212 (e.g., Figure 4 (As shown).

[0054] Please see Figure 1-4 In one embodiment of this utility model, the charging interface 30 includes a support 32 connected to the cable 40, and the height from the sliding surface 220 to the opening of the sliding groove 222 is more than 0.5mm less than the height of the support 32. The height difference between the sliding groove 222 and the support 32 facilitates manual manipulation of the support 32 of the charging interface 30.

[0055] Please see Figure 1-4 In one embodiment of this utility model, the abutting surface 23 and the sliding surface 220 are arranged perpendicularly to each other. A portion of the cable outlet 230 is formed on the sliding surface 220 and a portion is formed on the abutting surface 23. The two portions are connected to form an "L"-shaped cable outlet 230. When the cable 40 moves with the support 32 after it slides, there is sufficient clearance space for the cable 40 to move, and the cable 40 will not be scratched.

[0056] For further details, please refer to Figure 1-4 In one embodiment of this utility model, the width of the cable outlet 230 is 4mm to 8mm; the length of the portion of the cable outlet 230 formed on the sliding surface 220 is 2mm to 4.5mm, and the length of the portion of the cable outlet 230 formed on the abutment surface 23 is 2mm to 4.5mm. When the cable 40 moves along with the support 32 after it slides, there is sufficient clearance space for the cable 40 to move, making it less likely to rub against the cable outlet 230.

[0057] Please see Figure 1-5In one embodiment of this utility model, the outer wall surface of the telescopic cable is provided with a groove 41 to reduce the friction area with the cable outlet 230. The groove 41 reduces the friction area of ​​the telescopic cable and prevents damage to the telescopic cable. Specifically, multiple grooves 41 are provided, and the multiple grooves 41 can extend along the length and / or width of the cable body 40. The specific shape of the groove 41 is not limited here. When the charging interface 30 is housed in the sliding groove 222, it has a connecting surface that contacts the sliding surface 220. The support body 32 has a metal cover 320 on the side away from the connecting surface. The metal cover 320 makes it easy to identify the support body 32 that can be moved by hand. The corner of the support body 32 on the side that contacts the sliding surface 220 is rounded 321 to facilitate the sliding of the support body 32 on the sliding surface 220 and the sliding surface 221.

[0058] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model shall be determined by the protection scope of the claims.
