[0001] The present invention relates to the technical field of chargers, and particularly to an intelligent charger for 3C digital devices. Background Art

[0002] 3C digital devices are a general term for three categories of electronic products: computers, communications, and consumer electronics. With digital technology at the core, they cover life, office, and professional fields, such as computers, mobile phones, cameras, and speakers. When using 3C digital devices, chargers are an essential component. Chargers are generally divided into two types: wireless chargers and wired chargers, both of which complete the connection between the charger and the external power supply through the cooperation of the plug and the socket.

[0003] During the use of existing chargers, when connecting the plug to the socket, since there may be many plugs installed on the socket, there may be a situation where the remaining sockets do not match the contact pieces of the plug, thus affecting the use of the charger. Moreover, after the plug is installed, due to the fixed shape of its contact pieces, it may also be affected by the aging and deformation of the spring pieces of the socket jack, resulting in the inability to tightly press the contact pieces and affecting the use of the charger.

[0022] The following is a description of the preferred embodiments of the present invention with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0023] Combined with Figures 1 - 8As shown, according to an embodiment of the present invention, an intelligent charger for 3C digital devices is provided, including: a housing 1, at the top inside which a device body 2 is fixedly installed, and two contact pieces 3 are oppositely arranged inside the bottom opening thereof; On two opposite side walls of the contact piece 3, two storage grooves 31 that communicate with each other inside are oppositely opened, and a contact block 32 is slidably installed inside the opening at one end of the storage groove 31; A transmission disc 4, which is sleeved on the top of the corresponding contact piece 3, and a driving mechanism 9 is arranged between the two transmission discs 4 for driving the transmission disc 4 to rotate or move up and down reciprocally; An adjusting mechanism 7, the top of which is arranged on the bottom side of the transmission disc 4, and the bottom of which is arranged inside the corresponding contact piece 3, for driving the contact block 32 in the storage groove 31 to extend or retract. The driving mechanism 9 and the two contact pieces 3 are both connected to the device body 2 through an electrical connection assembly 8; A fixing cylinder 5, which is fixedly installed inside the bottom opening of the housing 1, and is connected to the two contact pieces 3 through a connecting piece 6.

[0024] In this embodiment, when using this improved charger, please refer to Figures 1, Figure 2 , Figure 3 and Figure 5 As shown, the driving mechanism 9 drives the transmission disc 4 to rotate, so as to drive the two contact pieces 3 to rotate towards or away from each other through the cooperation of the transmission disc 4 and the connecting piece 6, so as to adjust the angles of the two contact pieces 3, so that the charger can adapt to the installation positions of the three-hole and two-hole on the socket, facilitating the use of the charger; Please refer to Figures 1 - 6 As shown, after inserting the contact piece 3 into the socket jack, the driving mechanism 9 drives the transmission disc 4 to rotate in the reverse direction. Due to the mutual contact between the socket jack and the contact piece 3, the contact piece 3 remains at the original angle unchanged. At this time, the driving mechanism 9 drives the transmission disc 4 to move downward, thereby driving the adjusting mechanism 7 to operate, so that the contact block 32 extends from the storage groove 31 and closely fits with the socket spring 74 piece, so as to avoid the influence on the use of the charger due to the aging and deformation of the spring 74 piece and the inability to tightly press the contact piece 3; The driving mechanism 9 drives the transmission disc 4 to rotate forward. Due to the mutual contact between the socket jack and the contact piece 3, the contact piece 3 remains at the original angle unchanged. At this time, the driving mechanism 9 cooperates with the connecting piece 6 to drive the whole housing 1 to rotate, so as to adjust the angle of the housing 1, so that the space on the top side of the adjacent jacks on the socket can adapt to the installation of another charger, thereby avoiding insufficient installation space and affecting the installation of the charger on the socket.

[0025] In a further preferred embodiment of the present invention, as shown in Figure 1 and Figure 2 , the USB interface of the device body 2 extends to the top side of the housing 1; The bottom end of the fixing tube 5 extends to the bottom end of the housing 1, and the top end of the fixing tube 5 is gap-matched with the bottom side of the device body 2; In this embodiment, please refer to Figure 1 As shown, the USB interface located outside the housing 1 facilitates the connection between the charger cable and the device body 2; Please refer to Figure 1 and Figure 2 As shown, the fixing tube 5 with the bottom end outside the shell 1 facilitates the assembly of the fixing tube 5 and the shell 1. When assembling the fixing tube 5 and the shell 1, an adhesive is applied to the outer wall of the fixing tube 5, and then the top of the fixing tube 5 is inserted into the bottom opening of the shell 1 until the bottom end of the fixing tube 5 is fixed. The fixing tube 5 and the shell 1 can be fixed by the adhesive, and the assembly operation is convenient. The gap between the top of the fixing tube 5 and the device body 2 facilitates the arrangement of some electrical connection components 8 .

[0026] In a further preferred embodiment of the present invention, Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, the connecting member 6 includes an outer rotating disk 62, which is rotatably mounted in the bottom opening of the fixed cylinder 5, and two inner rotating disks 61 are relatively rotatably mounted thereon through bearings, and the upper and lower sides of the inner rotating disk 61 are coplanar with the upper and lower sides of the outer rotating disk 62, and the inner rotating disk 61 is slidably sleeved on the top of the corresponding electric shock sheet 3; In this embodiment, please refer to Figure 2 , Figure 3 , Figure 6 and Figure 8 As shown, when the electric shock sheet 3 rotates, since the inner rotating disk 61 and the outer rotating disk 62 are connected by a bearing, the friction between the outer rotating disk 62 and the fixed cylinder 5 is smaller than the friction between the inner rotating disk 61 and the outer rotating disk 62. When the transmission disk 4 rotates, the electric shock sheet 3 and the inner rotating disk 61 are driven to rotate synchronously in the outer rotating disk 62, thereby adjusting the angles of the two electric shock sheets 3; When adjusting the angle of the housing 1 , due to the mutual interference between the contact piece 3 and the socket of the power strip, the angle between the contact piece 3 and the outer turntable 62 remains unchanged, thereby driving the housing 1 to rotate through the fixing tube 5 to adjust the angle of the housing 1 .

[0027] In a further preferred embodiment of the present invention, Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, the transmission disk 4 includes two disks 41, between which a transmission gear 42 is coaxially fixedly installed, and the top end of the electric contact sheet 3 is fixedly passed through the corresponding transmission gear 42 and the corresponding two disks 41 and is coplanar with the top side of the top disk 41; In this embodiment, please refer to Figure 5 and Figure 3 As shown, the transmission disc 4 composed of two discs 41 and a transmission gear 42 meets the requirements of gear transmission and also reserves a driving position for pushing the transmission disc 4 from the outer peripheral side of the transmission disc 4 (the diameter of the transmission gear 42 is smaller than the diameter of the disc 41).

[0028] In a further preferred embodiment of the present invention, Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the adjustment mechanism 7 includes two piston push plates 72, and two air storage tanks 71 are oppositely provided on the bottom side of the bottom end disc 41, and the two air storage tanks 71 are oppositely arranged on the two sides of the corresponding electric shock sheet 3, and the interior of the air storage tank 71 is connected to the interior of the corresponding storage tank 31 through the connecting hole, and the top of the piston push plate 72 is slidably installed in the corresponding air storage tank 71; In this embodiment, please refer to Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, during the downward movement of the transmission disk 4, due to the mutual interference between the piston push plate 72 and the top side of the inner rotating disk 61, the piston push plate 72 is gradually inserted into the gas storage tank 71, thereby pushing part of the gas in the gas storage tank 71 into the connecting hole, and then the gas is introduced into the gas storage tank 71 through the connecting hole, so as to push the electric shock block 32 out of the storage tank 31 through the gas, thereby increasing the overall thickness of the part of the electric shock sheet 3, so that the socket spring 74 can stably conduct electrical energy to the electric shock sheet 3; After the electric shock block 32 extends out of the storage slot 31, due to the mutual interference between the electric shock block 32 and the socket housing 1, the electric shock piece 3 will not directly slide out of the socket of the socket when the plug is pulled.

[0029] In a further preferred embodiment of the present invention, Figure 3 , Figure 6 and Figure 7 As shown, the opening at the other end of the gas storage tank 71 is cylindrical, and a piston push rod 73 is slidably installed in the opening at the other end of the gas storage tank 71, and the piston push rod 73 is fixedly connected to the corresponding electric shock block 32; In this embodiment, please refer to Figure 3 and Figure 4As shown, the gas introduced into the storage tank 31 through the connection hole directly flows into the cylindrical opening of the storage tank 31. Subsequently, through the pushing of the piston push rod 73 by the gas, the contact block 32 is pushed out of the storage tank 31. Since the two storage tanks 31 are internally connected and the two contact blocks 32 receive the same thrust, and the space between the two piston push rods 73 and the inner walls of the two storage tanks 31 is small, injecting a small amount of gas into the storage tank 31 can push out the contact block 32. Moreover, when the air storage tank 71 sucks the gas in the storage tank 31, a stronger negative pressure cavity can be formed between the two round rods and the inner wall of the storage tank 31, so that the contact block 32 can receive a greater suction force during the reset process of the piston push plate 72, thereby enabling the contact block 32 to stably retract into the storage tank 31.

[0030] In a further preferred embodiment of the present invention, as Figure 4 、 Figure 6 and Figure 7 shown, a spring 74 is provided on the top side of the piston push plate 72, and both ends of the spring 74 are fixedly connected to the corresponding piston push plate 72 and the inner wall of the corresponding air storage tank 71 respectively; In this embodiment, please refer to Figure 4 、 Figure 6 and Figure 7 shown, during the upward movement of the transmission disk 4, due to the pushing of the spring 74 on the piston push plate 72 and the gravity of the piston push plate 72 itself, the piston push plate 72 retracted into the air storage tank 71 automatically slides out of the air storage tank 71, thereby forming a negative pressure cavity in the air storage tank 71 and sucking the gas flowing into the storage tank 31 back into the air storage tank 71. Furthermore, a negative pressure is formed in the air storage tank 71, and finally the contact block 32 is sucked into the contact piece 3. At this time, the contact piece 3 can be directly pulled out of the socket jack.

[0031] In a further preferred embodiment of the present invention, as Figure 3 、 Figure 7 and Figure 8 shown, the driving mechanism 9 includes a motor 92. A receiving groove 91 is opened at the central position of the top side of the fixed cylinder 5, and the motor 92 is fixedly installed on the inner bottom wall of the receiving groove 91. A control member 93 is fixedly installed at the top of the receiving groove 91 for supplying power to the motor 92 and controlling the operation of the motor 92. The driving end of the motor 92 is fixedly installed with a threaded rod 94, and both ends of the threaded rod 94 are rotatably connected to the outer turntable 62 and the cylinder wall of the fixed cylinder 5 respectively. A driving gear 95 is threadedly sleeved on the outer peripheral side of the threaded rod 94, and the driving gear 95 is meshed with two transmission gears 42; In this embodiment, (the control member 93 is mainly composed of a housing 1, a power supply, and a control chip. The control chip controls the operation or shutdown of the motor 92 by supplying power to or cutting off the power supply of the motor 92, and controls the forward or reverse rotation by controlling the positive and negative poles of the power supply for the motor 92), please refer toFigure 3 , Figure 7 and Figure 8 As shown in Figure 8 , during the use of the device, the threaded rod 94 is driven to rotate by the motor 92 (the housing of the motor 92 is fixed to the inner wall of the accommodation cavity by bolts or adhesion, etc.). Due to the friction between the threaded rod 94 and the driving gear 95, when the transmission gear 42 is not jammed, the driving gear 95 can drive the transmission gear 42 to drive the transmission disk 4 to rotate forward or backward. When the transmission gear 42 is jammed due to the contact and engagement of the contact piece 3 with the socket jack, since the transmission gear 42 and the driving gear 95 are jammed, the threaded rod 94 can no longer drive the driving gear 95 to rotate. At this time, the threaded rod 94 can only drive the driving gear 95 to move up or down during rotation. And due to the mutual contact of the driving gear 95 and the disk 41, the transmission disk 4 can be synchronously driven to move up or down.

[0032] In a further preferred embodiment of the present invention, as Figure 3 , Figure 5 , Figure 8 and Figure 9 As shown in Figure 9 , the electrical connection component 8 includes an annular groove 81 with a T-shaped cross-section, which is opened on the inner top wall of the fixed cylinder 5. A conductive rod 82 and a conductive rod 83 are slidably installed in the annular groove 81, and the bottom ends of the conductive rod 82 and the conductive rod 83 are respectively fixedly connected to the top ends of the two contact pieces 3. Two elastic conductive rings 84 are arranged on the inner ring wall of the annular groove 81 from top to bottom, and the inner ring walls of the two elastic conductive rings 84 are respectively in contact with the conductive rod 82 and the conductive rod 83. The control member 93 and the two elastic conductive rings 84 are both connected to the circuit board of the device body 2 through connecting wires; In this embodiment, please refer to Figure 3 , Figure 5 , Figure 8 and Figure 9 As shown in Figure 9 , during the rotation of the contact piece 3 or the fixed cylinder 5, the conductive rod 82 and the conductive rod 83 are always in contact with the elastic conductive ring 84 respectively, so as to always keep the circuit connection between the contact piece 3 and the circuit board inside the device body 2; After the installation between the plug and the socket is completed, if the battery in the control member 93 is not fully charged, part of the electric energy input into the device body 2 is input into the battery in the control member 93 through the connecting wire to charge the battery in the control member 93 until the battery is full. At this time, the control chip in the control member 93 controls the battery to disconnect from the connecting wire and stops charging the battery in the control member 93, so that the battery in the control member 93 always has sufficient electric energy to supply power to the motor 92.

[0033] In a further preferred embodiment of the present invention, as Figure 3 , Figure 8 and Figure 9As shown, an airbag 85 with an annular shape is fixedly sleeved on the outer peripheral wall of the elastic conductive ring 84, and the outer peripheral wall of the airbag 85 is fixedly connected to the inner wall of the annular groove 81; In this embodiment, please refer to Figure 3 and Figure 9 As shown, during the rotation of the first conductive rod 82 and the second conductive rod 83 around their own axes or around the axis inside the fixed cylinder 5, since the first conductive rod 82 and the second conductive rod 83 clamp the airbag 85 from both sides with the inner wall of the annular groove 81, the airbag 85 at the positions of the first conductive rod 82 and the second conductive rod 83 contracts and pushes the nearby part of the elastic conductive ring 84 towards the first conductive rod 82 or the second conductive rod 83. Eventually, the elastic conductive ring 84 at the corresponding position bends and deforms, respectively wrapping around the outer peripheral walls of the tops of the first conductive rod 82 and the second conductive rod 83, which can increase the contact area between the first conductive rod 82 and the second conductive rod 83 and the elastic conductive ring 84, facilitating the current conduction between the two. At the same time, a relatively large resistance can be applied between the outer turntable 62 and the fixed cylinder 5, so that when the motor 92 drives the transmission disk 4 to rotate or move downward, the fixed cylinder 5 will not be driven to rotate.

[0034] Working principle: When the intelligent charger is in use, the connection between the plug and the 3C digital device is completed through the charging cable. At this time, the internal control chip in the control member 93 completes the connection with the 3C digital device through the device body 2. Then, the adjustment of the plug of the intelligent charger can be carried out through the control program in the 3C digital device; When the remaining jacks on the socket strip cannot accommodate the installation of the plug, through the control program in the 3C digital device, the motor 92 is controlled to start and drive the threaded rod 94 to rotate forward or backward. Due to the friction between the threaded rod 94 and the driving gear 95 and the meshing between the driving gear 95 and the transmission gear 42, the forwardly rotating threaded rod 94 synchronously drives the two transmission disks 4 to rotate. And because the contact pieces 3 are fixed to the transmission disks 4, at this time, the two contact pieces 3 rotate around their own axes inside the outer turntable 62 through the inner turntable 61, so as to adjust the included angle between the two contact pieces 3, so that the two contact pieces 3 of the plug can adapt to the installation at the double-hole or three-hole positions on the socket strip. After the contact sheet 3 is inserted into the socket of the power strip, the motor 92 is used to drive the turntable to rotate in the opposite direction. Due to the mutual interference between the socket of the power strip and the contact sheet 3, the contact sheet 3 maintains its original angle unchanged, and due to the meshing of the transmission gear 42 and the driving gear 95, the driving gear 95 is synchronously stuck. At this time, the rotating threaded rod 94 pushes the driving gear 95 downward, and due to the mutual interference between the driving gear 95 and the disk 41, the downward moving driving gear 95 synchronously drives the transmission disk 4 to move downward synchronously. The piston push plate 72 and the top side of the inner rotating disk 61 are in conflict with each other, and the piston push plate 72 is gradually inserted into the gas storage tank 71, so as to push part of the gas in the gas storage tank 71 into the connecting hole, and then introduced into the cylindrical opening of the storage tank 31 by the connecting hole. Then, the gas pushes the piston push rod 73 to push the electric shock block 32 out of the storage tank 31, so as to increase the overall thickness of the part of the electric shock sheet 3, so that the socket spring 74 can be in close contact with the electric shock sheet 3, and then stably conduct the electric energy to the electric shock sheet 3; It should be noted that when the motor 92 drives the transmission disk 4 to rotate or move downward, due to the mutual interference between the conductive rod 1 82 and the conductive rod 2 83 and the conductive ring, a large resistance can be applied between the outer rotating disk 62 and the fixed cylinder 5, so that the outer rotating disk 62 and the fixed cylinder 5 will not rotate. When the plug and the socket strip are disassembled, the motor 92 drives the transmission disc 4 to rotate forward. Due to the stuck electric shock sheet 3, the rotating threaded rod 94 drives the transmission disc 4 to move upward until the top disc 41 contacts the top wall of the fixed cylinder 5. At this time, as the transmission disc 4 is reset, due to the push of the spring 74 on the piston push plate 72 and the gravity of the piston push plate 72 itself, the piston push plate 72 retracted into the air storage tank 71 automatically slides out of the air storage tank 71, thereby forming a negative pressure chamber in the air storage tank 71, and the gas flowing into the storage tank 31 is re-sucked into the air storage tank 71, thereby forming a negative pressure chamber in the air storage tank 71, and finally the electric shock block 32 is sucked into the electric shock sheet 3, and the electric shock sheet 3 can be directly pulled out from the socket of the socket strip; It should be noted that after the electric shock sheet 3 is inserted into the socket of the power strip, if the electric shock sheet 3 and the power strip spring 74 can conduct electricity normally, the control program in the 3C digital device will not control the electric shock block 32 to extend from the storage slot 31, thereby strengthening the connection between the electric shock sheet 3 and the spring 74; When the installation space reserved on the socket strip is not suitable for the installation of the plug, the motor 92 drives the transmission disc 4 to rotate in the reverse direction. At this time, due to the contact between the contact piece 3 and the socket hole of the socket strip and the mutual contact between the bottom disc 41 and the connecting member 6, the transmission disc 4, the driving gear 95 and the threaded shaft are all in a stuck state, so that the driving end of the motor 92 is stuck. At this time, the housing of the motor 92, the fixed cylinder 5 and the outer shell 1 are subjected to a large torsional force to overcome the resistance between the outer turntable 62 and the fixed cylinder 5 and the frictional force between the outer turntable 62 and the fixed cylinder 5. At this time, the outer shell 1 can rotate around the outer turntable 62, so as to adjust the angle of the outer shell 1, so that the space on the top side of the adjacent socket holes on the socket strip can adapt to the installation of another charger, or so that the plug can adapt to the installation of the remaining space on the socket strip; It should be noted that through the improved intelligent charger on the socket strip, the angle of the plug can be adjusted to leave space for the subsequent installation of the plug. The improved intelligent charger can also be installed on another socket strip. After the angle of the plug is adjusted, the plug of the improved intelligent charger can be installed at the corresponding position on the corresponding socket strip; It should be noted that during the rotation of the contact piece 3 or the fixed cylinder 5, due to the pressing of the top of the first conductive rod 82 and the second conductive rod 83 on the two elastic conductive rings 84, the airbag 85 at this position contracts and deforms, and the elastic conductive ring 84 at this position bends and deforms, so that part of the elastic conductive ring 84 wraps around the outer peripheral walls of the tops of the first conductive rod 82 and the second conductive rod 83, so as to increase the contact area between the elastic conductive ring 84 and the first conductive rod 82 and the second conductive rod 83, so that the elastic conductive ring 84 and the first conductive rod 82 and the second conductive rod 83 can stably transmit electric energy, and a resistance is applied between the outer turntable 62 and the fixed cylinder 5 through the contact between the tops of the first conductive rod 82 and the second conductive rod 83 and the elastic conductive ring 84.
