Abstract

This application discloses a power adapter cable outlet structure, relating to the field of power adapters. The adapter includes an adapter with a winding mechanism inside its cavity and a locking mechanism on one side. The winding mechanism includes a fixed rod fixedly installed inside the adapter, and a winding roller is provided on the outer surface of the fixed rod. This invention, through the action of the winding mechanism, can wind up the cable harness, facilitating the carrying of the adapter. Pulling the connector outward causes the cable harness to be released from the winding roller. After being pulled to the desired length, it is ready for use. During further pulling, the winding roller drives a circular plate to rotate outside the fixed rod, causing a torsion spring to twist. After use, because the torsion spring has been twisted and needs to return to its original position, the torsion spring drives the circular plate to rotate in the opposite direction, which in turn drives the winding roller to rotate, thereby winding up the cable harness. This design facilitates quick pulling out and winding of the cable harness.

Description

Technical Field

[0001] This utility model relates to the field of power adapter technology, and in particular to a power adapter cable output structure. Background Technology

[0002] As a key component for powering electronic devices, the power adapter's cable structure is crucial to user experience, safety, and lifespan. With the widespread use of electronic devices such as mobile phones, laptops, and tablets, the application scenarios for power adapters are becoming increasingly diverse. In scenarios such as daily office work, home use, and travel, it is inconvenient to store the adapter's cable bundle.

[0003] Simply plug the output of the power adapter into the port you want to charge, then plug the power adapter into a power strip to charge the device.

[0004] Existing power adapters have a single, exposed cable harness. When packed in a backpack, the cable can get tangled with other items, making it inconvenient to handle and use. Consequently, they lack the ability to retract the cable harness to meet market demands for portability. Therefore, a new cable routing structure for power adapters is proposed.

[0010] As a preferred embodiment of the power adapter cable outlet structure of this utility model, the snap-fit ​​mechanism includes circumferentially distributed toothed grooves on the outer surface of the circular plate, and the adapter is symmetrically equipped with fixing blocks inside, with a snap-fit ​​block provided on one side of the two fixing blocks opposite to each other.

[0011] In a preferred embodiment of the power adapter cable outlet structure described in this utility model, an elongated hole is provided on one side of the adapter, and a torsion spring is provided on one side of the circular plate.

[0015] In a preferred embodiment of the power adapter cable outlet structure described in this utility model, the other end of the torsion spring is fixedly connected to the adapter, and the push rod is slidably connected inside the square hole.

[0016] (III) Beneficial Effects

[0017] This utility model provides a power adapter cable outlet structure. It has the following advantages:

[0018] 1. The winding mechanism can wind up the wire harness for easy carrying of the adapter. Pulling the connector outward causes the wire harness to be released from the winding drum. After being pulled to the required length, it is ready for use. During the pulling process, the winding drum drives the circular plate to rotate outside the fixed rod. The circular plate drives the torsion spring to twist. After use, the torsion spring needs to be restored to its original state. At this time, the torsion spring drives the circular plate to rotate in the opposite direction. The circular plate drives the winding drum to rotate, thereby winding up the wire harness. This mechanism facilitates the quick pulling out and winding of the wire harness.

[0019] 2. The locking mechanism restricts the rotation of the circular plate. By manually pushing the push rod into the adapter, the push rod pushes the locking block to rotate around the axis. At this time, the spring is compressed and deformed, pushing one end of the locking block out of the tooth groove. The circular plate can then be rotated. When the circular plate stops rotating, the spring pushes one end of the locking block into the tooth groove, restricting the rotation of the circular plate. This restricts the rotation of the circular plate and thus controls the extension length of the wire harness. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Example 1

[0029] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present utility model. This embodiment provides a power adapter cable outlet structure, including an adapter 1. The inner cavity of the adapter 1 is provided with a winding mechanism 2, and a snap-fit ​​mechanism 3 is provided on one side of the winding mechanism 2.

[0030] The winding mechanism 2 includes a fixed rod 201 fixedly installed inside the adapter 1. A winding roller 209 is provided on the outer surface of the fixed rod 201. A conductive slide rail 208 is installed on one side of the winding roller 209, and a circular plate 207 is installed on the other side of the winding roller 209. A wire harness 205 is provided on the outer surface of the conductive slide rail 208, and a connector 210 is installed at one end of the wire harness 205.

[0031] Specifically, the take-up roller 209 is rotatably connected to the outside of the fixed rod 201, and one end of the wire harness 205 is connected to the conductive slide rail 208. The take-up roller 209 is a double-half design. One half of the conductive slide rail 208 is rotatably connected to the outside of the fixed rod 201, and the other half of the conductive slide rail 208 is fixedly installed on the outside of the fixed rod 201. The wire harness 205 is wound around the outside of the take-up roller 209. When the connector 210 is manually pulled outward, the wire harness 205 extends outward, which drives the take-up roller 209 to rotate, allowing the connector 210 to be plugged into the required position for power supply.

[0032] The adapter 1 has an elongated hole 203 on one side, and a torsion spring 206 is provided on one side of the circular plate 207.

[0033] Specifically, the other end of the torsion spring 206 is fixedly connected to the adapter 1. When the stretched wire harness 205 is rewound onto the take-up drum 209, the torsion spring 206 causes the circular plate 207 to rotate in the opposite direction, thereby winding the wire harness 205 to the outside of the take-up drum 209.

[0034] A U-shaped block 204 is symmetrically installed on one side of the connector 210, and a limit rod 202 is symmetrically installed on the outer surface of the conductive slide rail 208.

[0035] Specifically, under the action of the limiting rod 202, the stability of the conductive slide rail 208 is ensured, and the U-shaped block 204 is located on one side of the elongated hole 203 to prevent the connector 210 from moving from the elongated hole 203 into the interior of the adapter 1 after it is finished being wound up.

[0036] The wire harness 205 is slidably connected in the inner cavity of the elongated hole 203, the torsion spring 206 is located outside the fixing rod 201, and the other ends of the two limiting rods 202 are fixedly connected to the adapter 1.

[0037] Specifically, during winding and unwinding, the wire harness 205 moves inside the elongated hole 203, which facilitates orderly winding around the outside of the take-up roller 209 and prevents the wire harness 205 from becoming tangled during winding.

[0038] Furthermore, manually pull the connector 210. The connector 210 moves one end of the wire harness 205 outward. At this time, the wire harness 205 drives the take-up roller 209 to rotate. The take-up roller 209 drives half of the conductive slide rail 208 and the circular plate 207 to rotate on the fixed rod 201. The circular plate 207 twists the torsion spring 206. After pulling the wire harness 205 to the required length, insert the connector 210 into the appropriate interface, and then insert the adapter 1 into the power strip. Under the action of the conductive slide rail 208, the circuit of the wire harness 205 is ensured to be unobstructed. Finally, it can be charged through the connector 210.

[0039] Example 2

[0040] Reference Figure 4 and Figure 5 This is the second embodiment of the present invention, which is based on the previous embodiment and includes a snap-fit ​​mechanism 3 that limits the length of the wire harness 205 pulled out.

[0041] The snap-fit ​​mechanism 3 includes circumferentially distributed toothed grooves 305 on the outer surface of the circular plate 207. The adapter 1 has symmetrically installed fixing blocks 301 inside, and a snap-fit ​​block 303 is provided on one side opposite to the two fixing blocks 301.

[0042] Specifically, the locking block 303 is rotatably connected to the opposite side of the two fixed blocks 301, and the toothed groove 305 is adapted to one end of the locking block 303, which can lock one end of the locking block 303 inside the toothed groove 305, thus restricting the rotation of the circular plate 207.

[0043] A push rod 304 and a spring 306 are provided on one side of the locking block 303, and a square hole 302 is provided on one side of the adapter 1.

[0044] Specifically, push rod 304 is pushed into the adapter 1, and push rod 304 pushes block 303 to rotate around the pivot, so that one end of block 303 that is locked in the tooth groove 305 is moved out.

[0045] The other end of the torsion spring 206 is fixedly connected to the adapter 1, and the push rod 304 is slidably connected inside the square hole 302.

[0046] Specifically, under the action of the spring 306, when the locking block 303 is not subjected to external force, one end of the locking block 303 can be stabilized in the tooth groove 305.

[0047] Furthermore, manually push the push rod 304 into the adapter 1. The push rod 304 pushes the locking block 303 to rotate around the pivot. At this time, the spring 306 is compressed and deformed, pushing one end of the locking block 303 out of the toothed groove 305, pulling the wire harness 205 to drive the circular plate 207 to rotate. When the circular plate 207 stops rotating, remove the pushing force applied to the push rod 304. Under the action of the spring 306, push one end of the locking block 303 into the toothed groove 305 to restrict the rotation of the circular plate 207.

[0048] Working principle: The adapter 1 contains a circuit board, a transformer, and various electrical components. The conductive slide rail 208 is a pre-existing structure and is identical to those disclosed in existing designs. Manually pushing the push rod 304 into the adapter 1 causes the locking block 303 to rotate around the pivot. At this time, the spring 306 is compressed and deformed, moving the other end of the locking block 303 out of the toothed groove 305. One finger must continuously push the push rod 304. Then, manually pulling the connector 210 outwards causes the wire harness 205 to extend outwards. The wire harness 205 then causes the take-up roller 209 to rotate outside the fixed rod 201. The take-up roller 209 causes half of the conductive slide rail 208 and the circular plate 207 to rotate. The circular plate 207 causes the torsion spring 206 to twist, stretching the wire harness 205 to the required length. After this, the connector 210 is inserted into the corresponding interface. The other end of the wire harness 205 is connected to the conductive slide rail 208. With the wire harness 205 securely connected, the conductive slide rail 208 ensures the passage of the wire harness 205. Then, remove the force applied to the push rod 304. Under the action of the spring 306, one end of the locking block 303 is pushed into the toothed groove 305, restricting the rotation of the circular plate 207. Manually plug the adapter 1 into the power strip for charging. After charging, when the adapter 1 needs to be stored, manually push the push rod 304 again to push one end of the locking block 303 out of the toothed groove 305. At this time, under the action of the torsion spring 206, the torsion spring 206 drives the circular plate 207 to rotate in the opposite direction on the fixed rod 201. The circular plate 207 drives the winding roller 209 to rotate, winding the wire harness 205 until the two U-shaped blocks 204 are attached to one side of the adapter 1. The winding is then complete. Remove the force applied to the push rod 304. Under the action of the spring 306, one end of the locking block 303 is locked into the toothed groove 305, and the adapter 1 can be carried.
