Description

Technical Field

[0001] This utility model relates to the field of chargers, and in particular to a multi-functional charger. Background Technology

[0002] With the development of technology, various electronic devices have gradually entered thousands of households and become necessities in people's lives. As an essential accessory for electronic devices, chargers have also become indispensable electronic products in people's work and life.

[0003] Chargers are essential accessories for connecting electronic devices to power outlets, providing voltage and current to ensure the normal operation of electronic devices. Existing plug-in chargers typically have a circuit board installed inside. Traditionally, the plug prongs pass through the charger's housing, and the live and neutral wire prongs on the circuit board are connected to the parts of the charger that pass through the housing, allowing the charger to transmit current through the prongs. This type of plug-in charger, with its prongs and housing integrated into one piece, takes up a lot of space, is inconvenient to carry, and the metal prongs at the plug end are easily squeezed or scratched by other items placed with it when carrying it.

[0004] Later, a foldable plug device appeared on the market. It features a foldable design, allowing the first terminal and two second terminals to be simultaneously folded into the base. To allow the first terminal and two second terminals to fold outwards from the base during use, a latching element is also included. Pressing the latching element inwards causes it to rotate around a pivot, moving the latching part upwards to release the locking part of the first terminal. The insert then rotates around a retaining post under the elastic force of a second torsion spring, causing the first terminal and two second terminals to protrude from the base. The plug's... The internal structure is complex, requiring the pressing of the latch and the linkage of a series of parts such as the rotating shaft and the second torsion spring to make the terminal protrude from the base. Secondly, this type of plug device is affected by its own structure. Due to the lack of a power-off protection unit, the charger will continue to charge the battery regardless of whether it is fully charged, unless people manually disconnect the charger power. This not only wastes energy but also damages the battery of electronic devices. If the charging time is too long and the battery temperature becomes too high, there is a possibility of explosion, posing a great threat to personal safety.

[0005] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0006] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a multi-functional charger. Through the structural design and cooperation between the charger body and the power plug, the power plug is foldably mounted on a support frame via a rotating shaft. This allows the plug to remain in the pluggable position, reducing space occupation and further improving storage and portability. Secondly, the design of the charging circuit and power-off protection unit automatically disconnects the charging circuit from the mains power and provides power-off protection for the charger, enhancing its safety.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A multi-functional charger includes a charger body, a charging circuit, power plugs, a data cable, and a power failure protection unit; the charger body has a receiving cavity, and the charging circuit board is disposed within the receiving cavity;

[0009] The charger body has a pin slot and a cable slot arranged opposite each other; the pin slot has a support frame for fixing the power pin, and the power pin is folded and mounted on the support frame via a rotating shaft; when the power pin is in the folded state, the power pin is stored in the pin slot; when the power pin is in the unfolded state, at least a portion of the power pin extends out of the pin slot; the cable slot extends vertically along the charger body, and the data cable is folded and mounted in the cable slot;

[0010] The power failure protection unit includes a relay, a timing button, a timer, a display screen, a signal receiver, and a temperature sensor; the timing button is located at one end of the charger body and is electrically connected to the timer; the timer, temperature sensor, and signal receiver are each electrically connected to the relay; the relay is electrically connected to the charging circuit to turn the charging circuit on or off; the display screen is located on the front side of the charger body and is electrically connected to the timer.

[0011] As a preferred embodiment, the data cable includes a connection input head and a connection output head. The connection input head is electrically connected to the charging circuit; the connection output head is used to connect to a charging device. When the data cable is in a folded state, it is stored in the cable slot; when the data cable is in an unfolded state, the connection output head extends out of the cable slot. The design of the data cable allows for direct charging during use. Furthermore, the foldable design facilitates cable storage, making the plug aesthetically pleasing and more suitable for daily carrying and use.

[0012] As a preferred embodiment, several charging interfaces are also provided on the side of the cable tray, and the several charging interfaces are electrically connected to the charging circuit; the several charging interfaces are disposed in the receiving cavity, and the output ends of the several charging interfaces are exposed outside the charger body.

[0013] As a preferred embodiment, the power plug includes positive and negative power plugs; the charging circuit is connected to positive and negative contact springs arranged side by side, and each of the positive and negative contact springs has an elastic contact protrusion facing each other; the positive and negative power plugs are together disposed on the rotating shaft, and each of the positive and negative power plugs is electrically connected to an abutment protrusion facing the corresponding positive and negative contact spring, and the abutment protrusion of the positive and negative power plugs abuts against the elastic contact protrusion of the corresponding positive and negative contact springs to conduct electricity.

[0014] As a preferred embodiment, the temperature sensor is a thermistor.

[0015] As a preferred embodiment, the charger body includes a front cover and a rear cover, the front cover being fitted onto the rear cover to form a receiving cavity; the pin slot is recessed in the front cover; and the wire slot is recessed in the rear cover.

[0016] Compared with the prior art, this utility model has significant advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly relies on the structural design and cooperation between the charger body and the power plug. The charger body has a plug groove, and the power plug is foldably mounted on the support frame via a rotating shaft. When the power plug is in the folded state, it is stored in the plug groove. When the power plug is in the unfolded state, at least a portion of it extends out of the plug groove. Thus, when not in use, the plug can be stored in the plug groove, maintaining its retracted state. When in use, the plug can be unfolded from the plug groove and rotated to a pluggable position, maintaining its pluggable state, reducing space occupation, and further improving storage and portability.

[0017] Secondly, the design of the charging circuit and power-off protection unit is discussed. The power-off protection unit includes a relay, a timing button, a timer, a display screen, and a temperature sensor. Pressing the timing button starts the timer, displaying the set time on the screen. When the time is up, the timer sends a signal to the relay, which shuts down the charging circuit. Alternatively, a signal can be sent from the mobile terminal to a signal receiver, which then sends a signal to the relay, shutting down the charging circuit. When the temperature sensor detects excessively high temperatures inside the charger casing, it sends a signal to the relay, shutting down the charging circuit. This automatically disconnects the charging circuit from the mains power, providing power-off protection and enhancing the charger's safety. It prevents the charger from damaging itself prematurely or spontaneously combusting due to prolonged operation. Furthermore, the charger saves energy after a power outage, as it is no longer operating.
