Description

Technical Field

[0001] This utility model relates to the field of power charging equipment, and more particularly to a charger that facilitates the storage of cables. Background Technology

[0002] A charger is a safe and intelligent power conversion device that uses sophisticated electronic components and intelligent protocols to ensure an efficient, fast, and safe charging process, thereby extending the lifespan of the device's battery. Currently, most chargers on the market use a plug-in connection method, and they are generally used to connect to electronic products via a data cable.

[0003] In the process of realizing this application, the inventors discovered the following problems with the prior art: During the charging process of mobile phones, due to the increase in the power of the charger, it is difficult to effectively dissipate heat by relying solely on the heat dissipation of the outer casing, causing the temperature of the charger to rise sharply, even reaching extremely high levels; After the mobile phone is fully charged, people habitually leave the data cable directly on the power adapter. Since the data cable is generally quite long, it is easy for it to get tangled with other items, causing inconvenience to people to some extent.

[0004] Therefore, those skilled in the art have provided a charger that facilitates the storage of cables to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a charger that facilitates cable storage, prevents tangling, and improves heat dissipation efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A charger for easy cable storage includes a housing and a circuit board. A locking mechanism is movably provided on the top of the housing. A stepped shaft is fixedly provided inside the housing. A torsion spring is fixedly connected to one end of the stepped shaft, and a winding wheel is rotatably connected to the other end of the stepped shaft.

[0008] One side of the roller is rotatably mounted on the inner wall of the housing. An air inlet and an exhaust port are respectively opened at the upper and lower ends of the inner wall of one side of the housing. A fan is fixedly mounted on the inner wall of the other side of the housing.

[0009] Furthermore, a data cable is wound inside the reel, with one end of the data cable fixedly connected to the inside of the reel and the other end of the data cable fixedly connected to a converter.

[0010] Furthermore, one side of the torsion spring is fixedly connected to the inner wall of the housing, and the other side of the torsion spring is fixedly connected to the outer wall of the winding wheel. A vent hole is provided around the winding wheel near the inner wall of the housing.

[0011] Furthermore, the locking mechanism includes a locking rod, the outer side of which is movably disposed on the inner wall of the locking hole, and an operating plate is fixedly connected to the side of the locking rod away from the converter.

[0012] Furthermore, a compression spring is fixedly connected to one side of the operating plate, and the side of the compression spring away from the operating plate is fixedly connected to the inner wall of the groove at the top of the housing. The bottom end of the operating plate is movably disposed at the top of the housing.

[0013] Furthermore, a locking hole is provided through the center of the side wall of the converter, a protective sleeve is fixedly and symmetrically connected to one side of the converter, a plug is fixedly provided at the bottom end of the protective sleeve, and one side of the protective sleeve is snapped onto the top of one side of the housing.

[0014] Furthermore, when in use, the cross-section of the vent hole coincides with that of the air inlet and the air outlet, but when not in use, the cross-section of the vent hole does not coincide with that of the air inlet and the air outlet.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model proposes a charger that facilitates cable storage. Through the design of a torsion spring and a winding wheel, the data cable can be automatically wound up after use, avoiding tangling with other items and achieving cable storage. The locking mechanism design can fix the pulled-out data cable to prevent it from retracting into the housing during use. The plug design with symmetrically connected protective sleeves at the bottom allows for simultaneous charging of different devices.

[0017] 2. The present invention proposes a charger that facilitates cable storage. Through the design of a vent hole on one side of the reel and an air inlet and exhaust hole on the casing, when the charger is not in use, the vent hole does not coincide with the air inlet and exhaust hole, which can prevent dust from entering when not in use. When in use, pulling the data cable rotates the reel, causing the vent hole to coincide with the air inlet and exhaust hole, and the internal fan starts to circulate air, thereby enhancing the heat dissipation capacity during the charging process.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 , Figure 3 and Figure 4 The present invention provides an embodiment of a charger for convenient cable storage, comprising a housing 1 and a circuit board 2. A locking mechanism 13 is movably provided on the top of the housing 1. A stepped shaft 16 is fixedly provided inside the housing 1. A torsion spring 8 is fixedly connected to one end of the stepped shaft 16, and a winding wheel 5 is rotatably connected to the other end of the stepped shaft 16. One side of the torsion spring 8 is fixedly connected to the inner wall of the housing 1, and the other side of the torsion spring 8 is fixedly connected to the outer wall of the winding wheel 5. A data cable 7 is wound inside the winding wheel 5. One end of the data cable 7 is fixedly connected to the inside of the winding wheel 5, and the other end of the data cable 7 is fixedly connected to a converter 14.

[0026] The locking mechanism 13 includes a locking rod 11. The outer side of the locking rod 11 is movably disposed on the inner wall of the locking hole 15. An operating plate 18 is fixedly connected to the side of the locking rod 11 away from the converter 14. A compression spring 12 is fixedly connected to one side of the operating plate 18. The side of the compression spring 12 away from the operating plate 18 is fixedly connected to the inner wall of the groove at the top of the housing 1. The bottom end of the operating plate 18 is movably disposed at the top of the housing 1.

[0027] A locking hole 15 is provided through the center of the side wall of the converter 14. A protective sleeve 6 is fixedly and symmetrically connected to one side of the converter 14. A plug 10 is fixedly provided at the bottom end of the protective sleeve 6. One side of the protective sleeve 6 is snapped into a groove on the top side of the housing 1.

[0028] Specifically, circuit board 2 is the internal circuitry of the existing charger. When the data cable 7 is pulled out, the winding wheel 5 rotates. The torsional force stored in the fixed torsion spring 8 drives the winding wheel 5 to rotate and wind up the data cable 7 the moment it is released, thus achieving cable storage and preventing tangling with other items. Pulling the locking mechanism 13 allows the data cable 7 to be pulled out or wound up at will, and it can be fixed after being released. One side of the protective sleeve 6 is snapped onto the top of one side of the housing 1, providing protection for the plug 10 at one end of the data cable 7 when not in use. The protective sleeve 6 is fixedly and symmetrically connected to one side of the converter 14, and the plug 10 is fixedly installed at the bottom of the protective sleeve 6, enabling simultaneous charging of two devices and improving the user experience of the charger.

[0029] Reference Figure 2 and Figure 4 One side of the roller 5 is rotatably mounted on the inner wall of the housing 1. The upper and lower ends of the inner wall of one side of the housing 1 are respectively provided with an air inlet 4 and an exhaust 3. The other side of the inner wall of the housing 1 is fixedly provided with a fan 9. A ventilation hole 17 is provided around the roller 5 near the inner wall of the housing 1.

[0030] When in use, the cross-section of the vent 17 coincides with that of the air inlet 4 and the exhaust port 3; when not in use, the cross-section of the vent 17 does not coincide with that of the air inlet 4 and the exhaust port 3.

[0031] Specifically, when not in use, the vent 17 does not overlap with the air inlet 4 and the exhaust 3, preventing dust from entering during normal storage. When in use, pull out the data cable 7 and rotate the reel 5 to make the vent 17 overlap with the air inlet 4 and the exhaust 3. The circuit of the fan 9 is connected to the circuit board 2. After the circuit board 2 is powered on, the fan 9 runs, improving the heat dissipation capacity of the charger.

[0032] Working principle:

[0033] When using, first confirm the plug 10 required by the electronic device so that it can charge different devices, thus improving the device's versatility. Then, pull the operation plate 18 to squeeze the compression spring 12, so that the locking rod 11 can be removed from the locking hole 15. After taking out the converter 14 and pulling the data cable 7 out a sufficient distance, release the operation plate 18. The locking rod 11 will squeeze the data cable 7, which can fix the data cable 7 and prevent it from retracting into the housing 1 during charging.

[0034] Pulling out the data cable 7 causes the roller 5 to rotate, aligning the vent 17 with the air inlet 4 and the exhaust vent 3. The circuit of the fan 9 is connected to the circuit board 2. After the internal circuit board 2 is powered on, the fan 9 rotates, enabling the airflow inside the casing 1 and promoting the rapid dissipation of heat.

[0035] After charging is complete, pull the control panel 18 away from the locking mechanism 13, moving it away from the data cable 7. The winding wheel 5 rotates under the huge torsional torque of the torsion spring 8, winding up the data cable 7 to prevent it from getting tangled with other items. The protective sleeve 6 is then snapped into the groove at the top of one side of the housing 1, achieving cable storage. At the same time, the rotation of the winding wheel 5 also prevents the vent 17 on one side from aligning with the air inlet 4 and exhaust vent 3, preventing dust from entering when not in use and ensuring the cleanliness of the internal structure.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
