Detailed Description
Choose below the utility model relates to a better embodiment of the wireless charger of wrist-watch of area telescopic wire explains this technical scheme in detail.
The utility model provides a wrist-watch wireless charger of area telescopic line contains base 1, steel ball 2, clockwork spring 3, cell phone plug 5, shell 6, take-up reel 7, USB line 8, power supply circuit board 9, support 12, wireless charging circuit board 13, wireless charging module 14, face lid 15. Base 1, clockwork spring 3, take-up reel 7, power supply circuit board 9, support 12, wireless charging circuit board 13, wireless module 14 that charges, face lid 15 are arranged from making progress down along vertical direction in proper order. An EVA pad 1-1 is arranged on the base 1 for skid resistance. The base 1 is provided with a steel ball groove along the radial direction, and the steel ball groove is fully distributed with a circle around the circle center in the circumferential direction. The steel ball 2 is arranged in the steel ball groove and forms an assembly relation that the steel ball 2 can slide in the steel ball groove after being matched with the steel ball groove. Because the steel ball groove is fully distributed with a circle on the base 1 in the circumferential direction around the circle center, even if the steel ball 2 slides out of one steel ball groove, the steel ball can fall into the other steel ball groove, and the telescopic stability of the USB cable is ensured. A fixed shaft is arranged in the vertical direction at the center of the circle of the base 1, and a through groove is formed in the vertical direction of the fixed shaft. One end of the clockwork spring 3 penetrates through a through groove formed in the fixing shaft of the base 1 along the radial direction and then is fixed on the fixing shaft, the other end of the clockwork spring 3 is fixed on a winding roll 7, and the clockwork spring 3 is arranged between the winding roll 7 and the base 1. A steel sleeve 4 is sleeved on a fixed shaft of the base 1, and the steel sleeve 4 is positioned between the fixed shaft and a connecting surface of a through hole of the winding roll 7.
The winding roll 7 is provided with a through hole matched with the fixed shaft of the base 1, and the winding roll 7 is matched with the base 1 through the through hole to form a matching relation that the winding roll 7 can rotate on the fixed shaft of the base 1. The winding roll 7 is provided with a first ring groove and a second ring groove which can be used for the sliding of the steel balls 2, and the winding roll 7 is matched with the base 1 to form an assembly relation that the steel balls 2 are limited by the steel ball grooves on the base 1 and the ring grooves on the winding roll 7 together. As shown in fig. 7, the first ring groove rises spirally, and the first step is formed at the head-to-tail connection part of the ring grooves. The spiral of second annular groove rises and is different with the direction of rotation of first annular groove, and the annular end to end junction forms the fourth step. The first ring groove and the second ring groove are located in the same plane of the winding roll 7, and the first ring groove is located on the outer side of the second ring groove. The head-tail connection position of the first ring groove and the head-tail connection position of the second ring groove are staggered. A steel ball sliding groove is arranged between the head-tail connection part of the first annular groove and the second annular groove, and a third step is formed between the steel ball sliding groove and the second annular groove. The steel ball sliding groove and the head part of the first ring groove form a second step. The head part of the second ring groove is communicated with the first ring groove and has no step, and all the steps can pass through the steel ball. When the USB wire is stretched outwards, the winding roll rotates on the base, and the steel ball slides along the rising direction of the first ring groove. When the USB wire is stretched in place, the USB wire is loosened, the winding roll rotates in the reverse direction under the action of the clockwork spring, the steel balls fall into the steel ball sliding grooves through the second steps, the steel balls cannot slide in the steel ball sliding grooves in the reverse direction, and therefore the winding roll stops rotating, and the USB wire also stops shrinking. When the USB wire needs to be completely retracted into the shell, the USB wire is pulled outwards, the steel ball falls into the second annular groove through the third step, and in the process of retraction of the USB wire, the steel ball always slides in the second annular groove. When the USB wire is stretched outwards again, the steel ball enters the first ring groove to slide through the communication part between the head part of the second ring groove and the first ring groove, and the process is repeated.
As shown in fig. 8, the winding roll 7 is provided with a disc protrusion coaxial with the through hole of the winding roll 7, and the disc protrusion is provided with a quincunx groove for fixing one end of the USB cable 8. One end of the USB wire is clamped in the plum blossom groove. In the process of stretching the USB wire outwards, the stress direction of the USB wire gradually turns to A2 from A1, meanwhile, the plum blossom-shaped groove can provide a B-direction extrusion force for the USB wire, and the USB wire is firmly clamped in the plum blossom-shaped groove under the action of friction force. When the contact surface of the plum blossom groove and the USB line is a plane, the friction force is further enhanced.
The power supply circuit board 9 is fixed on the winding roll 7 by a screw 10, and the screw cover 11 is fixed on the fixed shaft of the base by the screw 10. The USB line 8 is electrically connected with the power circuit board 9. The housing 6 is disposed on the base 1 and connected by a snap. The bracket 12 is disposed within the housing 6 and is snap-fit connected thereto. The wireless charging circuit board 13 is disposed on the bracket 12 and electrically connected to the power circuit board 9 through four-pin elastic contacts. The wireless charging module 14 is disposed on the wireless charging circuit board 13 and electrically connected to the wireless charging circuit board. The face cover 15 is connected to the upper portion of the housing 6 via a snap fit. The USB plug of the USB cable 8 protrudes out of the housing 6.
As shown in fig. 6, the mobile phone plug 5 is electrically connected to the wireless charging circuit board 13, and the mobile phone plug 5 extends out of the housing 6. The mobile phone plug 5 comprises an inner wire sleeve 5-1 and an outer wire sleeve 5-2, the outer wire sleeve 5-2 is arranged at the through hole of the shell 6, and the outer wire sleeve 5-2 is sleeved outside the inner wire sleeve 5-1. The design of multiple wire sleeves buffers the pulling of the shaking of the mobile phone plug to the connection position of the mobile phone plug and the circuit board, and the connection firmness is improved.
The above embodiments are preferred embodiments of the present invention, and not all embodiments of the present invention. Any other solutions that can be derived by a person skilled in the art on the basis of or on the basis of this solution without any inventive step are within the scope of this solution.
