The specific meanings of the above terms in the present invention can be understood by those of ordinary skill in the art according to specific situations.

Referring to fig. 1, a first embodiment of the present invention provides an automobile filler device 1 for connecting an automobile power supply to charge an electronic product. The vehicle charging device 1 comprises a vehicle charging plug 10 and a telescopic data line 20, wherein the vehicle charging plug 10 is electrically connected with the telescopic data line 20. When the electronic product is charged, the vehicle charging plug 10 is connected with a vehicle power supply, and transmits electric energy to the electronic product through the telescopic data line 20.

Specifically, the retractable data line 20 further includes an input line 21, a receiving device 22, and at least one output line 23. The input wire 21 is telescopically received in the receiving device 22, and the receiving device 22 is partially exposed and electrically connected with the vehicle charging plug 10. One end of the output wire 23 is fixed in the receiving device 22 and electrically connected to the input wire 21, and the other end is exposed out of the receiving device 22.

As can be appreciated, since the input wire 21 is electrically connected to the vehicle charging plug 10, and the output wire 23 is electrically connected to the input wire 21, when the vehicle charging plug 10 is connected to a vehicle power source, electric energy can be transmitted to the input wire 21 through the vehicle charging plug 10 and to the output wire 23 through the input wire 21, and the electronic product can be charged through the output wire 23 being connected to the electronic product. And can telescopically accomodate input wire 21 in storage device 22, when not using car to fill device 1, can accomodate input wire 21 through storage device 22, and then avoid the mixed and disorderly winding of input wire 21 together, the input wire 21 after accomplishing accomodating is cleaner and tidier, and then makes car fill device 1 whole more pleasing to the eye. Meanwhile, the input wire 21 can be protected by the containing device 22, damage to the input wire 21 due to external force is avoided, and the service life of the input wire 21 is further prolonged. When the vehicle charging device 1 needs to be used, the input wire 21 is pulled out of the accommodating device 22, so that the charging distance of the vehicle charging device 1 can be adjusted, electronic products at different distances can be charged, and the practicability of the vehicle charging device 1 is further improved. And with storage device 22 and the components of a whole that can function independently setting up of car charging plug 10, can further reduce the whole volume of car charging plug 10, the car charging plug 10 of less volume can dock with the power source of car more nimble convenient, and the car charging plug 10 of less volume can adapt to more use scenes simultaneously, has further improved the practicality of car charging device 1.

Referring to fig. 2 and fig. 3, the receiving device 22 further includes a housing 221 and a rotating assembly 222. A rotating shaft 2211 is disposed inside the housing 221, the rotating assembly 222 is sleeved on the rotating shaft 2211 and rotatably connected to the rotating shaft 2211, and the input wire 21 is wound on the rotating assembly 222 to be exposed out of the housing 221 and electrically connected to the vehicle charging plug 10.

Specifically, the housing 221 includes an upper housing 2212 and a lower housing 2213, the upper housing 2212 and the lower housing 2213 are covered to form a mounting area, the upper housing 2212 is provided with a wire through hole 22122, and the rotating shaft 2211 is disposed in the mounting area and integrally formed with the upper housing 2212. The rotating assembly 222 further includes a wire rack 2221, the wire rack 2221 is disposed in the installation area, and the input wire 21 is wound around the wire rack 2221 and then extends out of the housing 221.

More specifically, the wire holder 2221 is further provided with a boss 22211, a wire winding portion 22212, and a support portion 22213. The winding portion 22212 has a generally annular configuration and is supported by the support portion 22213 with the boss 22211 disposed inside the winding portion 22212. The wire holder 2221 is fitted over the shaft 2211 through the shaft housing 22211 and is accommodated in the mounting area. The winding portion 22212 defines an opening, one end of the input wire 21 is fixed on the shaft housing 22211 through the opening, and the other end thereof is wound on the winding portion 22212 and extends out of the wire through hole 22122 to be connected to the vehicle charging plug 10.

As can be appreciated, since the rotating assembly 222 is sleeved on the rotating shaft 2211 of the housing 221, the input wire 21 can be received in the housing 221 by winding the input wire 21 on the rotating assembly 222, so as to further achieve the receiving and protecting of the input wire 21. Meanwhile, when the input wire 21 extends out of the storage device 22, because the rotating assembly 222 is rotatably connected with the rotating shaft 2211, the acting force of the input wire 21 acting on the rotating assembly 222 does not drive the rotating assembly 222 to move, thereby avoiding the rotating assembly 222 from shifting due to external force, and ensuring that the vehicle charging device 1 can repeatedly stretch or wind the input wire 21 in the using process.

With continuing reference to fig. 2 and fig. 3, the rotating assembly 222 further includes a cover 2222, the cover 2222 covers the wire rack 2221 and defines a winding area for inputting the wire 21 with the wire rack 2221.

Specifically, the cover 2222 is disposed at an opposite side of the support 22213 and detachably coupled to the wire holder 2221, and the wire winding portion 22212 is clamped between the cover 2222 and the support 22213. Therefore, the input wire 21 wound around the winding portion 22212 is also sandwiched between the cover 2222 and the support portion 22213. It can be understood that the winding area of the input wire 21 defined by the cover 2222 and the wire holder 2221 can limit the input wire 21, so as to prevent the input wire 21 wound on the wire holder 2221 from being separated from the wire holder 2221.

Referring to fig. 3 and 4, in order to position and automatically wind the input wire 21, the receiving device 22 further includes a locking component 223, and the rotating component 222 further includes a core 2223 connected to the wire rack 2221. The elastic element 22231 is disposed inside the core 2223, the rotating cover 22232 is disposed on one side of the core 2223 away from the wire holder 2221, and the locking component 223 is disposed on one side of the casing 221 corresponding to the rotating cover 22232 and is matched with the rotating cover 22232 to limit the rotation of the core 2223 for positioning.

Further, the elastic member 22231 is a clockwork spring having one end positioned on the rotation shaft 2211 and the other end positioned on the hub 2223. As the hub 2223 rotates, the spring coil spring can apply a restoring force to the hub 2223 to cause the hub 2223 to have a tendency to return. Of course, the elastic member 22231 may be an elastic member such as a spring block, as long as it can provide a restoring force to make the wheel core 2223 have a tendency to return when the wheel core 2223 rotates.

Referring to fig. 4 to 6, in particular, the locking assembly 223 further includes an elastic device 2231, a connecting device 2232 and a gear 2233. Wherein, a wheel groove 22233 is arranged on the wheel cover 22232, one end of the connecting device 2232 is provided with a projection 22321 matched with the wheel groove 22233, the other end of the connecting device 2232 is abutted against the elastic device 2231 through a convex column 22322, one side of the connecting device 2232 close to the gear 2233 is also provided with a first convex block 22323 and a second convex block 22324, and the gear 2233 is arranged between the first convex block 22323 and the second convex block 22324. The adjacent two tooth grooves of the gear 2233 have different depths and are respectively defined as a first tooth groove 22331 and a second tooth groove 22332. The first gullet 22331 is engaged with the first protrusion 22323, and the second gullet 22332 is engaged with the second protrusion 22324. For ease of understanding, embodiments of the present invention are described with the depth of the first gullet 22331 (shown as D in fig. 6) being greater than the depth of the second gullet 22332 (shown as D in fig. 6), and should not be construed as limiting.

In summary, when the user needs to pull the input wire 21 out of the housing 221, the user pulls one end of the input wire 21 to drive the wire holder 2221 to rotate, and drives the wheel cover 22232 to rotate synchronously. The protrusion 22321 of the coupling device 2232 is disengaged from the groove 22233 and allows the coupling device 2232 to be deviated from its original position, and the elastic device 2231 gives a restoring force to the coupling device 2232. When the user releases his hand, the elastic member 22231 inside the wheel core 2223 is reset, which drives the wheel core 2223 to rotate and recover the stretched input wire 21, however, the elastic means 2231 drives the connecting means 2232 to reset, the second protrusion 22324 on the connecting means 2232 is engaged with the second slot 22332 of the gear 2233, and the connecting means 2232 is fixed. Meanwhile, the projection 22321 of the connecting device 2232 swings through a certain angle, and the projection 22321 stops in the wheel groove 22233 of the wheel cover 22232, so that the wheel cover 22232 stops rotating, and finally the wheel core 2223 stops rotating, which plays a role in positioning.

When the user needs to store the input wire 21, the user pulls one end of the input wire 21 again to rotate the pulley cover 22232 again. At the same time, the protrusion 22321 of the linking device 2232 is disengaged from the wheel groove 22233 again and the linking device 2232 is deflected from its original position again, and the elastic device 2231 gives a restoring force to the linking device 2232. When the user releases his hand, the elastic member 22231 inside the wheel core 2223 is reset, and at the same time, the elastic means 2231 drives the connecting means 2232 to be reset, the first protrusion 22323 of the connecting means 2232 is engaged with the first tooth groove 22331 of the gear 2233, and the connecting means 2232 is fixed. However, since the depth of the first tooth slot 22331 is greater than the depth of the second tooth slot 22332, when the connecting device 2232 is fixed, the protrusion 22321 on the connecting device 2232 swings through a greater angle than the protrusion 22321 swings through when paying out, and the protrusion 22321 stops outside the wheel slot 22233 of the wheel cover 22232, and thus the wheel cover 22232 cannot be prevented from rotating. Finally, the stretched input wire 21 is completely withdrawn by the elastic member 22231.

It can be understood that, when the user pulls the input wire 21 out of the storage device 22 to a suitable charging distance, the length of the input wire 21 pulled out of the storage device 22 can be limited by positioning the wire rack 2221, so that the input wire 21 is prevented from being wound into the storage device 22 during the use of the car-charging device 1, and the convenience of the user in using the car-charging device 1 is further improved. Meanwhile, the clamping component 223 is matched with the wheel core 2223, so that the input wires 21 which are stretched out can be completely withdrawn, the function of one-time wire take-up is realized, the operation is simple and convenient, and the working efficiency is high.

Further, the shape of the rotating assembly 222 is not specifically limited in the embodiment of the present invention, and the rotating assembly 222 may be any one of a circular rotating assembly, a triangular rotating assembly, an oval rotating assembly, a racetrack-shaped rotating assembly, or a square rotating assembly.

It can be appreciated that by providing the rotating assembly 222 with different contour shapes, the user can select the rotating assembly 222 according to personal preference, which further improves the selectivity of the car charger 1. Meanwhile, the rotating assemblies 222 with different contour shapes can be suitable for different use scenes, and a user can select the rotating assemblies 222 with different contour shapes according to different use scenes, so that the practicability of the car filling device 1 is further improved.

Referring to fig. 1 and 7, as an embodiment, the rotating element 222 is a racetrack-shaped rotating element. Specifically, the casing 221 is a runway-shaped casing matched with the rotating assembly 222, two straight line segments of the casing are provided with avoiding holes 2214, and the avoiding holes 2214 are through holes communicated with the installation area, so as to avoid interference between the rotating assembly 222 and the casing 221 when rotating.

Referring to fig. 8, as another embodiment, the rotating element 222 is a circular rotating element. Specifically, the housing 221 is a circular housing that is matched with the rotating assembly 222, the housing 221 is hollow to form a mounting area, and the rotating assembly 222 is mounted in the housing 221 and rotates in the housing 221.

Referring to fig. 9, further, the output wire 23 is further provided with an output port 231, and the output port 231 is disposed outside the housing 221 and is connected to the electronic product.

The Type of the output port 231 is not specifically limited in the embodiment of the present invention, and optionally, the output port 231 may be one of a Micro USB interface, a Type-C interface, or a Lightning interface. It can be understood that, by setting different kinds of output ports 231, the charging of the electronic products with different interfaces can be realized, and the practicability of the vehicle charging device 1 is greatly improved.

The number of the output wires 23 is not specifically limited in the embodiment of the present invention, and the vehicle charging device 1 may be provided with one output wire 23, two output wires 23, or a plurality of output wires 23. As an embodiment of the present invention, the vehicle charging device 1 includes three output wires 23, one end of each of the three output wires 23 is electrically connected to the input wire 21, and the other end is exposed out of the casing 221. The output port 231 of each output wire 23 may be one of a Micro USB interface, a Type-C interface, or a Lightning interface. Specifically, the output ports 231 of the three output wires 23 are respectively a Micro USB interface, a Type-C interface and a Lightning interface. It can be understood that three electronic products can be charged simultaneously by arranging the three output wires 23, and the practicability of the car charging device 1 is further improved.
