Background

The mobile phone shell is divided into PC shell, leather, silica gel, cloth, hard plastic, leather sheath, metal toughened glass shell, soft plastic, velvet, silk and other products according to the texture. The mobile phone shell not only serves as an ornament to enable the mobile phone to be a landscape, but also can protect the mobile phone, and is anti-falling, anti-scraping, waterproof and shockproof. But the functionality of the mobile phone shell is yet to be further expanded.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a multifunctional mobile phone shell with a charging device, which can protect a mobile phone and can be charged at any time.

The technical scheme disclosed by the utility model is that the multifunctional mobile phone shell comprises a shell body; the bottom surface of the shell is provided with a concave part capable of accommodating the charging device; the charging device comprises a fixed shaft, a rotary disc, a coil spring and a charging wire; the fixed shaft is arranged on the inner wall of the concave part, the rotary disc and the coil spring are sleeved on the fixed shaft, one end of the coil spring is fixed on the fixed shaft, and the other end of the coil spring is connected with the rotary disc; the charging wire is wound on the turntable and stretches or contracts along with the rotation of the turntable; the charging wire both ends are equipped with USB socket and cell-phone interface respectively, the depressed part is equipped with two outlet, can supply USB socket and cell-phone interface to stretch out respectively.

The mobile phone interface is one or more of a miniusb interface, a type-c interface or a lightning interface, and can adapt to mobile phones of different models. The USB jack can be directly plugged into a power plug and then connected with a power supply to charge the mobile phone.

The during operation drives the carousel through the both ends of pulling the charging wire and rotates to the compression coil spring, when loosening the charging wire both ends, the resilience force of coil spring drives carousel antiport, thereby with the charging wire shrink to the carousel on.

The outer edge of the turntable is provided with a ratchet wheel, the inner wall of the concave part is hinged with a pawl matched with the ratchet wheel, and the pawl is also provided with a return spring for keeping the pawl and the ratchet wheel matched; a pressing device capable of pressing the pawl to be disengaged from the ratchet wheel is further arranged on the side wall of the concave part; the pressing device comprises a connecting rod, a spring sleeved on the connecting rod and a button connected to the tail end of the connecting rod; the head end of the connecting rod penetrates into the concave part and points to the ratchet wheel; one end of the spring is connected to the outer wall of the concave part, and the other end of the spring is connected with the button.

The inner wall of the depressed part is hinged with the pawl through an upright column arranged on the inner wall of the depressed part, a return spring is sleeved on the upright column, one end of the return spring is fixedly connected with the upright column, and the other end of the return spring is connected with the pawl.

The during operation, the ratchet is contradicted to the pawl head end, and the ratchet can only forward rotation, and reverse rotation will be by the card post, can avoid the coil spring shrink by oneself when external force is lost, and this just guarantees that the tensile length of charging wire can maintain length unchangeable under the no external force condition, and the charging wire is automatic to be retrieved when not worrying to charge. When having filled the electricity, when the line was received to the needs, only need press the button gently, the button drives the head end of connecting rod and is close to and press the pawl tail end to the pawl tail end, and the pawl head end breaks away from the ratchet, and when the external pulling force was lost to the charging wire, the coil spring can drive the carousel antiport and retrieve the charging wire on the carousel. After the winding is finished, the button is loosened, the spring returns to the original state, so that the connecting rod is pulled to return, the tail end of the pawl is not pressed any more by the connecting rod, the pawl loses the external force effect, the head end of the pawl props against the ratchet wheel again under the effect of the reset spring, and the charging wire is prevented from automatically retracting.

The two wire outlets are symmetrically arranged on the side wall of the depressed part. The best scheme is that the lower wire outlet extends out of a mobile phone interface to be conveniently and directly inserted into a charging port below the mobile phone, and the upper wire outlet extends out of a USB socket to be inserted into a USB interface of a power plug and then connected with a power supply for charging or directly inserted into a USB interface of a computer for charging.

The width of the USB socket and the width of the mobile phone interface are both larger than the width of the wire outlet. USB socket and cell-phone interface can block like this in the depressed part and expose in the depressed part, avoid the retraction of coil spring to retrieve the charging wire both ends to the depressed part in, it is more convenient to use.

And a power plug is also arranged in the concave part.

According to the utility model, the charging device is arranged in the mobile phone shell, two ports of the charging wire are exposed out of the mobile phone shell, the mobile phone shell can be stretched by force when in use, the charging is finished, the charging wire is automatically recovered into the mobile phone shell, and the mobile phone shell is very convenient to use. Secondly, the casing of the mobile phone is also provided with a ratchet and pawl device, so that the pawl can prevent the reverse rotation of the ratchet wheel to cause the automatic recovery of the charging wire during charging; thirdly, press device can guarantee after charging, presses the pawl through the button, and the pawl breaks away from the ratchet, and the charging wire can be retrieved fast smoothly. Fourthly, the charging wire is retrieved the back that finishes, loosens the button, and the pawl loses external force to press, cooperates with the ratchet once more under reset spring's effect, avoids the automatic recovery of charging wire when acting as go-between.
