[0024] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0025] like Figures 1 to 7 As shown, Figures 1 to 7 The diagram shows a first embodiment of the pull-out charging cable storage device of the present invention. It includes a housing 1 and a cable outlet 11 disposed on one side of the housing 1. The cable outlet 11 is connected to the inner cavity 12 of the housing 1. The inner cavity 12 of the housing 1 is provided with a cable reel 2, a charging cable 3, a pop-out component 4 and a locking mechanism 5. One end of the charging cable 3 is wound around the cable reel 2 and is used for electrical connection with the circuit board. The other end of the charging cable 3 is provided with a charging plug 31, which supplies power to electronic devices through the plug portion 32 of the charging plug 31.

[0026] The locking mechanism 5 includes a trigger 51 and a locking reset assembly 52. ​​The trigger 51 is disposed on the adjacent side wall of the outlet 11. The locking reset assembly 52 is locked to the charging plug 31 to fix and lock the charging plug 31 built into the housing 1, preventing the charging plug 31 from being exposed outside the housing 1. One end of the trigger 51 is connected to the locking reset assembly 52, and the other end of the trigger 51 is exposed on the surface of the housing 1 for easy operation by the user. When the user presses the trigger 51, the trigger 51 can control the locking reset assembly 52 to unlock, so that the charging plug 31 is in an unlocked and disengaged state. The pop-out assembly 4, which abuts against the charging plug 31, can pop the unlocked charging plug 31 out of the outlet 11, so that the user can charge through the charging plug 31, or pull the charging plug 31 until the charging cable 3 reaches the required length for charging. After the user finishes charging, the charging cable 3 can be automatically rotated and stored back into the housing 1 by the set cable reel 2 and wound back to the cable reel 2. Then, the user can overcome the elastic force of the pop-out component 4 and push the charging plug 31 back into the housing 1 through the cable outlet 11 until the charging plug 31 is locked back into the locking and reset component 52. At this time, the charging plug 31 is fixed back into the housing 1 to protect the charging plug 31 and avoid unnecessary collisions and wear during storage and carrying, thereby improving the safety of the device. Moreover, the overall operation is simple and quick, and it is highly practical, which can meet the user's needs for convenient and safe use.

[0027] It should be noted that the reel 2 is existing technology, and its working structure and principle will not be described in detail here.

[0028] Specifically, the locking and resetting assembly 52 is located on one side of the charging plug 31. The locking and resetting assembly 52 includes a locking member 521 and a first elastic resetting member 522. The two ends of the first elastic resetting member 522 abut against the locking member 521 and the inner wall of the housing 1, respectively. The locking member 521 is connected to the trigger member 51. The side wall of the charging plug 31 is provided with a locking groove 33 that is adapted to the locking member 521. The locking groove 33 is wrapped around one side wall of the charging plug 31, and the locking member 521 is locked and connected to the locking groove 33. In the initial state, the first elastic reset member 522 locks the driving locking member 521 with the locking groove 33 under elastic force, thus fixing the charging plug 31 relatively in the housing 1. When the user needs to charge, the trigger member 51 can drive the locking member 521 to overcome the elastic force of the first elastic reset member 522 and move away from the locking groove 33, thus unlocking and separating the charging plug 31 from the locking member 521. At this time, the charging plug 31 can be ejected to the outside of the outlet 11 by the energy-stored ejection component 4, so that the user can connect to the device to be charged by pulling out the charging plug 31 located outside the housing 1. Correspondingly, when charging is completed, the user can push the charging plug 31 back to the initial position, so that the locking groove 33 of the charging plug 31 and the locking member 521 re-lock and connect, thus fixing the charging plug 31 relatively in the housing 1 again, which can effectively protect the charging plug 31.

[0029] Preferably, the first elastic reset member 522 is a spring, but this is not a limitation.

[0030] Furthermore, a through hole 53 for the charging plug 31 to pass through is formed between the trigger member 51 and the locking member 521. The width of the through hole 53 is greater than the thickness of the charging plug 31, thereby facilitating the movement of the charging plug 31 within the through hole 53. One end of the trigger member 51 is connected to one end of the locking member 521. The trigger member 51 and the locking member 521 can move relative to the charging plug 31, thereby driving the locking member 521 to overcome the elastic force of the first elastic reset member 522 and move away from the locking groove 33, thus unlocking and separating the charging plug 31 from the locking member 521. At this time, the charging plug 31 can be ejected to the outside of the outlet 11 by the energy-stored ejection component 4, allowing the user to connect to the device to be charged by pulling out the charging plug 31 located outside the housing 1.

[0031] The locking member 521 has an abutment portion 523 and a protrusion 524 at both ends. One end of the first elastic reset member 522 is nested on the protrusion 524 and abuts against the locking member 521 to improve the connection between the first elastic reset member 522 and the locking member 521, and to prevent the first elastic reset member 522 from easily separating from the locking member 521, which would affect the unlocking and locking functions of the charging plug 31. The abutment portion 523 abuts against one end of the trigger member 51, so that the trigger member 51 can drive the locking member 521 to move, thereby realizing the unlocking function of the charging plug 31. The locking member 521 is provided with a locking block 525, which is located on the inner side wall of the through hole 53. The locking block 525 is locked and connected with the locking groove 33 to improve the locking connection firmness or locking effect. When the trigger 51 drives the locking member 521 to press the first elastic reset member 522, the locking block 525 and the locking groove 33 gradually separate. When the locking block 525 and the locking groove 33 are in the unlocked and separated state, the charging plug 31 is in the unlocked and fixed state. At this time, the pop-out force of the pop-out component 4 can pop the charging plug 31 out of the housing 1, so as to facilitate the user's charging and use.

[0032] To enable the built-in charging plug 31 to automatically pop out, the pop-out assembly 4 includes a push-out member 41 and a second elastic reset member 42. The two ends of the second elastic reset member 42 abut against the inner wall of the housing 1 and the push-out member 41, respectively. The end of the charging plug 31 furthest from the outlet 11 abuts against the push-out member 41. Initially, the second elastic reset member 42 is compressed. When the user controls the locking member 521 to unlock and separate from the charging plug 31 via the trigger member 51, the pop-out assembly 4, under the elastic force of the second elastic reset member 42, controls the push-out member 41 to drive the charging plug 31 out of the housing 1, thus facilitating charging. When the user pushes the charging plug 31 back to its initial position, the charging plug 31 must overcome the elastic force of the second elastic reset member 42 until it is in its initial position and locked with the locking member 521, thus re-fixing the charging plug 31 back into the housing 1.

[0033] Preferably, the second elastic reset member 42 is a spring, but this is not a limitation.

[0034] Furthermore, the push-out member 41 has an abutment groove 411 at one end near the charging plug 31, and a wire-passing hole 412 is formed in the abutment groove 411; the charging cable 3 passes through the wire-passing hole 412 and connects to the charging plug 31, and one end of the charging plug 31 connected to the charging cable 3 is inserted into the abutment groove 411 and abuts against the inner wall of the abutment groove 411, thereby improving the connection effect between the push-out member 41 and the charging plug 31 and improving the pop-out effect of the pop-out component 4. The wire-passing hole 412 makes it easy for the charging cable 3 to pass through the push-out member 41, making it convenient for the user to pull out the charging cable 3.

[0035] The push-out member 41 has an outwardly extending abutting end 413 at one end near the second elastic reset member 42. One end of the second elastic reset member 42 is nested on the abutting end 413 and abuts against the push-out member 41 to improve the connection effect between the second elastic reset member 42 and the push-out member 41, and to avoid affecting the pop-out function of the charging plug 31 due to the second elastic reset member 42 easily separating from the push-out member 41.

[0036] Preferably, a guide boss 414 is provided on one side of the ejector 41, and a slide rail groove 13 adapted to the guide boss 414 is provided on the inner wall of the housing 1; the guide boss 414 and the slide rail groove 13 are slidably connected, and the sliding direction of the slide rail groove 13 is the same as the wire outlet direction of the outlet 11. Thus, through the guiding effect of the guide boss 414 and the slide rail groove 13, it is ensured that the ejector assembly 4 stably ejects the charging plug 31 to the outlet 11, so as to provide convenient charging for the user.

[0037] like Figure 8 As shown, Figure 8 This diagram shows a structural schematic of a second embodiment of the pull-out charging cable storage device of this utility model. This embodiment is similar to... Figures 1 to 7 The difference from the first embodiment shown is that the trigger 51 is located on the same side wall as the outlet 11.

[0038] The locking and unlocking of the charging plug 31 can also be controlled by the sliding trigger 51. For example, the sliding trigger 51 can drive the locking member to move away from the locking groove, overcoming the elastic force of the first elastic reset member, thereby realizing the unlocking function of the charging plug 31. The charging plug 31 can then be ejected by the ejector component, making it available for user charging. The working principle of this embodiment is the same as that of the first embodiment, and will not be described in detail here.

[0039] This utility model also provides a charging device, including the above-mentioned pull-out charging cable storage device and a circuit board, with the circuit board disposed in the housing of the pull-out charging cable storage device; the charging device can preferably be a socket, adapter, conversion socket or power bank or other device capable of charging electronic devices.

[0040] In summary, this utility model automatically ejects the charging plug built into the housing through the trigger and ejection components, allowing the user to charge the device or pull out the charging cable for charging. After charging is complete, the user can push the charging plug back into the housing until it re-locks with the locking and reset components. At this point, the charging plug is fixed back into the housing, protecting it from unnecessary collisions and wear during storage and transport, thus improving the device's safety. Moreover, the overall operation is simple, quick, and highly practical.

[0041] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
