Description
Technical Field
[0001] This utility model belongs to the technical field of power chargers, specifically relating to a PD fast charging cable reel power charger. Background Technology
[0002] Most existing chargers use a separate cable and charging head design. While these products offer some flexibility in usage scenarios, the scattered accessories increase the difficulty of daily storage. It is easy to lose the cable or charging head due to carelessness when carrying them, which can lead to situations where charging cannot be done in time due to incomplete accessories. Although a few integrated chargers have solved the problem of separate accessories, they are larger in size to accommodate multiple charging needs, and have protruding sharp designs such as protruding prongs. When carried around, they not only take up a lot of space, but may also scratch other items. In the event of an accidental collision, they can also easily cause scratches or punctures to the human body, making them less portable and less safe. Utility Model Content
[0003] The purpose of this invention is to provide a PD fast charging cable reel power charger to address the aforementioned problems.
[0004] This utility model is achieved through the following technical solution: a PD fast charging cable reel power charger, including a housing and a lower cover fixedly installed at the lower end of the housing. The housing contains a telescopic cable module and a PCB board. The lower cover contains a folding plug module. Both the telescopic cable module and the folding plug module are electrically connected to the PCB board. The PCB board is fixedly inserted between the housing and the lower cover and abuts against the inner side wall of the housing. The telescopic cable module is installed in the middle of the housing. The telescopic cable module includes a telescopic winding cable body, a Type-C plug, and a flexible protective sleeve located at the connection between the Type-C plug and the winding cable body. The top of the housing has a first through hole adapted to the horizontal insertion of the Type-C plug. The housing also contains a USB-C connector, which is electrically connected to the PCB board. The top of the housing also has a second through hole adapted to the shape of the USB-C connector.
[0005] Furthermore, the length of the first through hole is greater than the sum of the lengths of the Type-C plug and the flexible protective sleeve. When the winding body is fully wound up, the Type-C plug and the flexible protective sleeve can be horizontally embedded in the first through hole. When the winding body is unwound, the Type-C plug and the flexible protective sleeve extend outward from one end of the first through hole.
[0006] Furthermore, the second through hole is located in the direction that extends outward from the end of the Type-C plug when it is laid horizontally.
[0007] Furthermore, a top cover is fixedly installed on the upper end of the housing. The top cover is provided with a plug hole adapted to the second through hole and a receiving groove adapted to the first through hole. The receiving groove is embedded in the first through hole. A third through hole is opened at the junction of the side wall and the bottom of the receiving groove, which is relatively far away from the plug hole, for the winding wire and the flexible protective sleeve to pass through.
[0008] Furthermore, the flexible protective sleeve has a stop at the end that is relatively far from the Type-C plug, and there are protrusions at the two included angles of the first through hole and the third through hole. The distance between the two protrusions is greater than the width of the wound wire and less than the width of the stop on the flexible protective sleeve.
[0009] Furthermore, the flexible protective sleeve has a plurality of spaced limiting protrusions arranged around its outer periphery along its length.
[0010] In use, the Type-C plug is pulled out of the first through-hole, and the Type-C plug is pulled outward to unfold the winding cable. Then, the folding plug module on the lower cover is opened, allowing the plug to extend outward and be fixed. This allows the device to be connected to a power source for charging. When charging is complete and storage is needed, the folding plug module is closed, and the plug folds back into the lower shell. The winding cable is then wound until the flexible protective sleeve at the bottom of the Type-C plug is located in the first through-hole. The flexible protective sleeve is bent so that the Type-C plug is horizontally inserted into the first through-hole for storage. After storage, the charger has no protruding sharp structures, making it safe to carry without risk of injury. The integrated Type-C plug avoids the problem of losing too many accessories, greatly improving portability and practicality. Furthermore, the charger can also be used via a USB-C interface, adapting to different user needs and habits. Attached Figure Description

Detailed Implementation
[0016] The present invention will be further illustrated below with reference to specific examples and accompanying drawings.
[0017] like Figures 1-3 As shown, this utility model describes a PD fast charging cable reel charger, including a housing 1 and a lower cover 2 fixedly installed at the lower end of the housing 1. The housing 1 contains a telescopic cable module 3 and a PCB board 4. The lower cover 2 contains a folding plug module 21. Both the telescopic cable module 3 and the folding plug module 21 are electrically connected to the PCB board 4. The PCB board 4 is fixedly inserted between the housing 1 and the lower cover 2 and abuts against the inner side wall of the housing 1. The telescopic cable module 3 is installed in the middle of the housing 1. The telescopic cable module 3 includes a telescopic winding cable body 31, a Type-C plug 32, and a flexible protective sleeve 33 located at the connection between the Type-C plug 32 and the winding cable body 31. The top of the housing 1 has a first through hole 11 adapted to the horizontal insertion of the Type-C plug 32. The housing 1 also contains a USB-C connector 5, which is electrically connected to the PCB board 4. The top of the housing 1 also has a second through hole 12 adapted to the shape of the USB-C connector 5.
[0018] In use, the Type-C plug 32 is pulled out from the first through hole 11, and the Type-C plug 32 is pulled outward to unfold the winding cable 31. Then, the folding plug module 21 on the lower cover 2 is opened to extend and fix the plug outward. The device and power supply can then be connected to this utility model for charging. When charging is complete and storage is required, the folding plug module 21 is closed to fold the plug back into the lower shell. The winding cable 31 is then wound until the flexible protective sleeve 33 at the lower end of the Type-C plug 32 is located in the first through hole 11. The flexible protective sleeve 33 is bent so that the Type-C plug 32 is horizontally embedded in the first through hole 11 for storage. After storage, the charger has no protruding sharp structures, making it less likely to cause injury or damage to objects when carried, and ensuring good safety. The charger also features an integrated Type-C plug 32, avoiding the problem of too many accessories being easily lost and inconvenient to carry, greatly improving the portability and practicality of the charger. Furthermore, the charger can also be used via a USB-C interface, adapting to different user needs and habits.
[0019] In this embodiment of the present invention, the length of the first through hole 11 is greater than the sum of the lengths of the Type-C plug 32 and the flexible protective sleeve 33. When the winding body 31 is fully wound up, the Type-C plug 32 and the flexible protective sleeve 33 can be horizontally embedded in the first through hole 11. When the winding body 31 is unwound, the Type-C plug 32 and the flexible protective sleeve 33 extend outward from one end of the first through hole 11. That is, the outlet position of the telescopic cable module 3 corresponds to one end below the first through hole 11. After the winding body 31 is wound up, the Type-C plug 32 and the flexible protective sleeve 33 are located at both ends of the first through hole 11. At this time, the telescopic cable module 3 is completely housed in the housing 1. During the process of housing the Type-C plug 32, the flexible protective sleeve 33 protects the connection between the Type-C plug 32 and the winding body 31, preventing wear and breakage caused by repeated bending after long-term use.
[0020] In this embodiment of the present invention, the second through hole 12 is located in the direction of outward extension of the end of the Type-C plug 32 in the horizontal position. That is to say, when the Type-C plug 32 is detached from the first through hole 11 and used, the USB-C connector 5 below the second through hole 12 will not be blocked by the pulled-out coiled cable 31. Thus, while using the Type-C plug 32, a corresponding external charging cable can also be connected to the USB-C connector 5 to charge two devices at the same time, avoiding defects such as cable tangling caused by the USB-C connector 5 and the Type-C plug 32 being too close together.
[0021] In this embodiment of the utility model, a top cover 6 is fixedly installed on the upper end of the housing 1. The top cover 6 is provided with a plug hole 61 adapted to the second through hole 12 and a receiving groove 62 adapted to the first through hole 11. The receiving groove 62 is embedded in the first through hole 11. A third through hole 621 is opened at the junction of the side wall and the bottom of the receiving groove 62 that is relatively far away from the plug hole 61, for the winding wire and the flexible protective sleeve 33 to pass through. The top cover 6 covers the first through hole 11 to prevent dust. The third through hole 621 on the receiving groove 62 provides space for the winding wire. The receiving groove 62 itself can be used to store the bent Type-C plug 32 and the flexible protective sleeve 33, so as to prevent the Type-C plug 32 from being trapped inside the housing 1 and unable to be pulled out due to the first through hole 11 being too open.
[0022] To further restrict the Type-C plug 32 from falling into the housing 1 from the third through hole 621, this embodiment of the invention preferably has a limiter at the lower end of the flexible protective sleeve 33 to lock onto the first through hole 11. Specifically, the flexible protective sleeve 33 has a stop block 331 at the end relatively away from the Type-C plug 32, and the first through hole 11 has protrusions 111 at the two included angles corresponding to the position of the third through hole 621. The distance between the two protrusions 111 is greater than the width of the wound wire and less than the width of the stop block 331 on the flexible protective sleeve 33. That is to say, the wound wire can move freely between the two protrusions 111, while the flexible protective sleeve 33 is restricted to moving only above the first through hole 11 due to the stop block 331, so as to avoid the wound wire from over-winding and causing the flexible protective sleeve 33 and the Type-C plug 32 to fall below the first through hole 11 and become unusable.
[0023] In this embodiment of the invention, the flexible protective sleeve 33 is provided with a plurality of spaced limiting protrusions 332 along its length. When the flexible protective sleeve 33 bends at the connection between the Type-C plug 32 and the wound wire, two adjacent limiting protrusions 332 move between the two until they abut against each other. Thus, the bending angle between two adjacent limiting protrusions 332 is limited, which can limit the maximum bending angle at the connection, prevent excessive bending from causing the connection to break, and effectively extend the service life of the product.
[0024] The above embodiments are merely preferred embodiments of the present utility model and are only used to explain the present utility model, not to limit the present utility model. Any changes, substitutions, combinations, simplifications, modifications, etc., made by those skilled in the art without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
