Description

Technical Field

[0001] The invention relates to the technical field of electronic products, in particular to a magnetic charging head for a watch. Background Art

[0002] The watch magnetic charging head is a device that uses magnetic attraction to tightly adsorb the watch to the charging base to achieve charging. It usually consists of two parts: a charging head and a charging port. The charging head is used to provide power, while the charging port is connected to the charging head through magnetic attraction to conduct current and help charge the watch. Specifically, there are two metal columns exposed to the outside in the charging head, which are conductive columns. These are the contact points for magnetic charging. When charging, you need to align the connector of the magnetic charging cable with this metal point on the back of the watch, and make sure that the charging cable fits tightly against the back of the watch. Then, plug the charging cable connector into a power outlet. When the charging icon appears on the watch screen, it means that charging has begun. The entire charging process will be controlled by the power management chip, and the chip circuit is set in the charging head.

[0003] However, the two conductive posts on the surface of the charging head are exposed to the outside. During use, after charging is completed, the user often directly unplugs the charging head and then lets go. The charging head naturally falls on the placement surface, or on the table, or on the chair. Therefore, the exposed conductive posts are easily bumped by accidents. These accidents may cause the conductive posts to wear and bend, and may also cause the conductive posts to be contaminated, ultimately causing poor contact of the conductive posts and affecting charging. At the same time, when the charging head is in operation, the chip circuit board inside it will also generate heat. The outer shell itself hinders the heat dissipation of the circuit board, which can easily cause the temperature of the circuit board to rise, aggravate the aging of the circuit, and seriously affect the service life of the charging head itself.

[0037] The telescopic protection mechanism 13 includes an insulating sleeve 131, a horizontal plate 132, a through slot 133, a vertical column 134 and a connecting column 139. The number of the insulating sleeves 131 is two groups. Each conductive column body 4 corresponds to an insulating sleeve 131.

The surface of the horizontal plate 132 is penetrated with a through slot 133. The vertical column 134 is bolted to the inside of the shell 1. The vertical column 134 is slidably connected to the inner wall of the through slot 133. Under the cooperation of the vertical column 134 and the through slot 133, the insulating sleeve 131 can drive the horizontal plate 132 to slide along the surface of the vertical column 134, which enables the insulating sleeve 131 and the conductive column body 4 to move in the vertical direction, telescoping. The protection mechanism 13 also includes an intermediate plate 135 bolted to the upper part of the interior of the shell 1, and inclined blocks 1311 are arranged on both sides of the intermediate plate 135.

The inner wall of the sleeve frame 137 performs horizontal sliding movement, and the blocking plate 138 can move back and forth. The top of the inclined block 1311 is bolted with a vertical plate 1310, and the vertical plate 1310 and the connecting column 139 are bolted to each other. First compression springs 1314 are fixed on both sides of the middle plate 135, and the other end of the first compression spring 1314 is fixed to the vertical plate 1310. A short connecting rod 1315 is also fixed to one side of the insulating sleeve 131, and the other end of the short connecting rod 1315 is bolted with a triangular block 1316.

Under the reaction force of the first compression spring 1314, the vertical plate 1310, the inclined block 1311, the connecting column 139 and the blocking plate 138 are subjected to a force away from the middle plate 135. The blocking plate 138 has a tendency to move toward the through hole 12. The insulating sleeve 131 can move in the vertical direction. The inclined block 1311 and the triangular block 1316 are in contact with each other. When the insulating sleeve 131 moves upward, it can drive the short connecting rod 1315 and the triangular block 1316 to move upward together. Moreover, the triangular block 1316 can slide along the surface of the inclined block 1311 and push the inclined block 1311 to move toward the middle plate 135, so that the first compression spring 1314 is in a compressed state.The vertical plate 1310, the connecting column 139 and the blocking plate 138 on the surface move in a direction away from the through hole 12, so that the blocking plate 138 is opened. On the contrary, when the insulating sleeve 131 moves downward, it drives the triangular block 1316 to move downward along the surface of the inclined block 1311. At this time, the inclined block 1311 moves under the reaction force of the first compression spring 1314. The inclined block 1311, the vertical plate 1310, the connecting column 139 and the blocking plate 138 move in a direction away from the middle plate 135. The blocking plate 138 blocks the through hole 12.

The support column 1313 is slidably connected to the inner wall of the transverse groove 1312. When the inclined block 1311 moves in the horizontal direction, the inclined block 1311 can slide along the surface of the support column 1313 through the transverse groove 1312, thereby supporting the inclined block 1311 and increasing the movement stability of the inclined block 1311. The cross section of the vertical column 134 is square in design, and the inner wall of the through groove 133 is square in design.

[0038] The control mechanism 14 includes a knob 141, a sleeve 142, an inner rod 143 and a rack 144. The sleeve 142 is rotatably connected to the inside of the housing 1 and extends to the outside of the housing 1. The inner rod 143 is slidably connected to the inner wall of the sleeve 142.

The inner diameters of the positioning sleeves 1410 are the same, and the first positioning sleeve 149 and the second positioning sleeve 1410 are both on the same vertical line. The surface of the knob 141 is concave and convex to prevent slipping during rotation. By rotating the knob 141, the knob 141 drives the inner rod 143 to rotate, and the inner rod 143 drives the sleeve 142 and the transmission gear 145 on the surface thereof to rotate. The transmission gear 145 drives the rack 144 to move in the vertical direction, and the rack 144 can drive the insulating sleeve 131 and the conductive column body 4 to move in the vertical direction together. The inner rod 143 moves in the direction, and in the process of turning the knob 141, the knob 141 can be pressed, which drives the inner rod 143 to retract into the interior of the sleeve 142, and the inner rod 143 squeezes the second compression spring 147, and the inner rod 143 drives the pin 148 to move. Then, the knob 141 is released again, and under the action of the second compression spring 147, the inner rod 143 drives the pin 148 to move, and the pin 148 enters the first positioning sleeve 149 or the second positioning sleeve 1410, so as to fix the sleeve 142.

[0039] The sealing protection mechanism 15 includes a connecting plate 151, a sealing cover 152 and a rotating column 155. The rotating column 155 is fixed to the bottom of the housing 1 through a bearing seat, which enables the rotating column 155 to rotate. One end of the connecting plate 151 is fixed to the rotating column 155, and the sealing cover 152 is bolted to the connecting plate 151, which enables the sealing cover 152 to be bolted. The sealing protection mechanism 15 also includes a vertical transmission column 158, which is rotatably connected to the housing 1, and a second bevel gear 154 is fixed to one end of the vertical transmission column 158. The surface of the sleeve 142 is fixed with a first bevel gear 153, and the first bevel gear 153 and the second bevel gear 154 are fixed to the first bevel gear 153. They are meshed with each other, and the other end of the vertical transmission column 158 extends to the outside of the shell 1 and is fixed with a third bevel gear 156. A fourth bevel gear 157 is fixed to one end of the rotating column 155, and the third bevel gear 156 and the fourth bevel gear 157 are meshed with each other. The first bevel gear 153, the second bevel gear 154, the third bevel gear 156 and the fourth bevel gear 157 are all made of plastic, and the sealing cover 152 and the connecting plate 151 are also made of plastic to reduce the weight of the entire charging head. The number of copper sheets 8 is several and is equidistantly arranged, and the area of ​​the sealing cover 152 is larger than the distribution range of the copper sheets 8, so that the sealing cover 152 can completely cover the copper sheets 8.

[0040] Working principle: Before use, the sealing cover 152 is in a closed state, and the pin 148 is inserted into the second positioning sleeve 1410 below, and the upper blocking plate 138 is sealed with the through hole 12. At the same time, the insulating sleeve 131 and the conductive column body 4 are located inside the shell 1. When charging is required, first press the knob 141 to drive the inner rod 143 and the pin 148 to move, so that the pin 148 is separated from the second positioning sleeve 1410 below, and then rotate the knob 141 counterclockwise, which can drive the inner rod 143, the sleeve 142, and the transmission gear 145 to rotate counterclockwise, and the transmission gear 145 drives the meshing therewith. The rack 144 moves upward, and the rack 144 drives the cross plate 132, the insulating sleeve 131, and the conductive column body 4 to move upward, and at the same time drives the short connecting rod 1315 and the triangular block 1316 to move upward, and the triangular block 1316 slides along the surface of the inclined block 1311 and pushes the inclined block 1311 to move toward the direction of the middle plate 135. The inclined block 1311 drives the blocking plate 138 to move together through the connecting column 139, so that the blocking plate 138 is away from the through hole 12, and the closed state of the through hole 12 is released. After that, the conductive column body 4 passes through the through hole 12 and is located outside the housing 1, and in the process of turning the knob 141 counterclockwise, it drives the sleeve The first bevel gear 153 on the surface of 142 rotates counterclockwise, and then the first bevel gear 153 drives the second bevel gear 154, the vertical transmission column 158 and the third bevel gear 156 to rotate counterclockwise, thereby driving the fourth bevel gear 157 and the rotating column 155 to rotate counterclockwise, thereby driving the sealing cover 152 to rotate through the connecting plate 151, so that the sealing cover 152 is in an open state, leaking the copper plate 7 below, and the conductive column body 4 is located on the outside of the housing 1, and the pin 148 is aligned with the first positioning sleeve 149 above, and the knob 141 is released. Under the action of the second compression spring 147, the pin 148 enters the first positioning sleeve 149 Inside, the position of the sleeve 142 is fixed, and the positions of the conductive column body 4 and the sealing cover 152 are fixed. At this time, pick up the watch that needs to be charged, and align the charging port on the surface of the watch with the conductive column body 4. Under the action of the magnet body 3, the charging head is adsorbed and fixed to the watch for charging. At the same time, the copper sheet 8 is exposed to the outside of the housing 1. The heat generated by the circuit board body 5 during operation is transferred to the copper sheet 8 through the silicone grease layer 6 and the copper sheet 7. The copper sheet 8 is fully in contact with the external air to achieve heat exchange, thereby greatly reducing the temperature of the circuit board body 5 and preventing the circuit board body 5 from being too high due to the heat dissipation hindered by its own shell;After charging is completed, it is only necessary to first release the connection between the watch itself and the charging head, then turn the knob 141 clockwise, and press the knob 141 at the same time to disengage the pin 148 from the first positioning sleeve 149, and the knob 141 drives the sleeve 142, the transmission gear 145, and the first bevel gear 153 to rotate clockwise, and then the rack 144 drives the insulating sleeve 131 and the conductive column body 4 to descend, so that the conductive column body 4 enters the through hole 12, and the triangular block 1316 follows the decline, and the inclined block 1311 pushes the connecting column 139, the vertical plate 1310 and the blocking plate 138 to move under the action of the first compression spring 1314, and the blocking plate 138 re-seals the through hole 12, thereby isolating the internal space of the shell 1 from the outside, that is, ensuring that the conductive column body 4 can be properly It is often in and out of the housing 1 to achieve protection and normal charging functions, and it can also prevent the entry of external dust and impurities. When the knob 141 is turned clockwise, the vertical transmission column 158 below rotates clockwise, and the third bevel gear 156 and the fourth bevel gear 157 drive the rotating column 155 to rotate counterclockwise, so that the sealing cover 152 is closed and fits on the bottom surface of the housing 1, and the copper sheet 8 is sealed and protected, and the copper sheet 8 is also prevented from being worn or contaminated on the outside, which affects the heat dissipation effect; the wire body 2 can be partially fixed by taking the ferrule 11 on the surface of the bottom plate 10, and the ferrule 11 is a semi-arc design. The wire body 2 is pressed into the inside of the ferrule 11, and the wire body 2 can be simply stored. ;
