[0025] This utility model proposes a multifunctional rugged mobile phone charging stand.

[0026] like Figures 1 to 4As shown in one embodiment of this utility model, a multifunctional rugged mobile phone charging stand includes a charging stand body 1. The upper end of the charging stand body 1 is provided with a charging slot 2 for inserting a rugged mobile phone for charging. The charging slot 2 is provided with first contact points 3 on opposite sides. The charging stand body 1 is provided with a through groove 4 at the bottom of the charging slot 2, which connects to the bottom. A cylindrical fan blade 5 is rotatably connected to the charging stand body 1 at the through groove 4. Rotating shafts at both ends of the cylindrical fan blade 5 are fixedly connected to rotating wheels 16. A plurality of permanent magnets 17 are evenly provided around the rotating wheels 16. The charging stand body 1 is provided with mounting cavities at both ends of the through groove 4. The rotating wheels 16 are movably installed in the mounting cavities. A plurality of conductive coils 13 are evenly provided around the rotating wheels 16 as the center. A battery compartment 22 is provided on one side of the bottom of the charging stand body 1. A second contact point 23 is provided on one side of the battery compartment 22. A sealing cover 25 is installed at the opening of the battery compartment 22. A baffle 15 is provided on one side of the upper end of the through groove 4.

[0027] In this embodiment, a cylindrical fan blade 5 is installed in the through slot 4, and a portion of the cylindrical fan blade 5 is blocked by a baffle 15. This allows the cylindrical fan blade 5 to rotate through water flow or natural wind, causing the permanent magnet 17 on the rotating wheel 16 to rotate and generate a magnetic field change, thereby generating current in the conductive coil 13. The battery compartment 22 can be used to install a spare battery for a rugged phone to store the electrical energy generated by the conductive coil 13. After energy storage, the battery can be directly installed in the rugged phone for emergency power supply. The sealing cover 25 can seal the battery compartment 22 to prevent water seepage. The battery can be placed in a vertically flowing water stream and the water flow can be directed towards the cylindrical fan blade 5 to generate electricity. Alternatively, one end of the charging base can be tied with a rope and the charging base can be dropped into flowing water, where the water flow impacts the cylindrical fan blade 5 to generate electricity. The through slot 4 of the charging base can also be aligned with the direction of natural wind, where the natural wind drives the cylindrical fan blade 5 to rotate and generate electricity.

[0028] Specifically, the charging base body 1 is made of high-strength, water-resistant, and corrosion-resistant engineering plastics, such as reinforced polycarbonate (PC). The reinforced polycarbonate material is injection molded into the shape of the charging base body 1. At the top of the charging base body 1, a charging slot 2 is injection molded according to the size and shape of the rugged phone. Slots for installing the first electrical contact 3 are reserved on opposite sides of the charging slot 2. Both the first electrical contact 3 and the second electrical contact 23 are made of highly conductive and oxidation-resistant metal materials, such as copper alloy, and are silver-plated to reduce contact resistance and improve conductivity. The cylindrical fan blades 5 are made of lightweight and high-strength plastic materials, such as polypropylene (PP), and are manufactured using injection molding. The rotating wheels 16 are made of plastic, and the permanent magnets 17 are high-performance neodymium iron boron magnets, evenly embedded around the circumference of the rotating wheels 16. Each rotating wheel 16 is equipped with 8-10... A permanent magnet 17; the conductive coil 13 is made of enameled wire, which is wound into a ring coil; the battery compartment 22 is integrally injection molded with the charging base body 1, and the material is the same as that of the charging base body 1; the sealing cover 25 is made of rubber material, which has good sealing performance and can effectively prevent moisture from seeping in; the size of the sealing cover 25 is closely matched with the opening of the battery compartment 22, and it is fixed to the battery compartment 22 by snap-fit ​​or threaded connection; a baffle 15 is installed on one side of the upper end of the through groove 4 by injection molding or subsequent assembly.

[0029] The specific assembly steps are as follows: First, the pre-processed first contact point 3 is fixed to the slots on both sides of the charging slot 2 using screws or welding. Ensure the first contact point 3 is flush with the surface of the charging base body 1 and accurately positioned to make good contact with the charging interface of the rugged mobile phone inserted into the charging slot 2. Connect the first contact point 3 to the internal circuit of the charging base, and insulate the connection point with insulating tape to prevent short circuits. Then, align the shafts at both ends of the cylindrical fan blade 5 with the rotating shaft mounting hole in the center of the rotating wheel 16, and insert the rotating shaft into the shaft hole. Ensure the cylindrical fan blade 5 and the rotating wheel 16 are firmly connected and that the cylindrical fan blade 5 can rotate freely on the rotating wheel 16. The rotating shaft can be fixed with an interference fit or glue to ensure connection stability. Finally, install the assembled cylindrical fan blade 5 and rotating wheel 16 into the mounting cavities at both ends of the through slot 4 of the charging base body 1. Ensure the rotating wheel 16 can rotate freely within the mounting cavity, and that the permanent magnet 17 on the periphery of the rotating wheel 16... Maintain an appropriate gap between the rotating wheel 16 and the conductive coil 13, and use screws or other fixing methods to fix the rotating shaft of the rotating wheel 16 in the mounting cavity to prevent axial movement of the rotating wheel 16 during rotation; install the wound and insulated conductive coil 13 on the charging base body 1, evenly arranged around the rotating wheel 16 with the rotating wheel 16 as the center, and seal it with glue to seal the wire coil; put the spare battery into the battery compartment 22, ensuring that the battery electrodes are in good contact with the second contact point 23, and then install the sealing cover 25 at the opening of the battery compartment 22, and fix the sealing cover 25 firmly by means of snap or thread connection to ensure good sealing between the sealing cover 25 and the battery compartment 22 to prevent moisture from seeping into the battery compartment 22. When there is an external power source for charging, the charging slot 2 can charge the rugged phone, and the battery compartment 22 can charge the battery of the rugged phone. Both can be charged individually or together.

[0030] Preferably, floating plates or floating chambers are fixedly connected to the periphery of the charging base body 1, so that the charging base body 1 can float in the water and allow water to flow through the through groove 4 to rotate the cylindrical fan blade 5, thereby reducing the resistance of the cylindrical fan blade 5, further increasing the rotational speed of the cylindrical fan blade 5, and increasing the power generation efficiency.

[0031] Preferably, such as Figure 1 As shown, the width of the baffle 15 is half the width of the through groove 4. The cylindrical fan blade 5 is installed in the middle of the through groove 4 to prevent airflow or water flow from impacting the cylindrical fan blade 5 in the part blocked by the baffle 15, generating a force in the opposite direction to the cylindrical fan blade 5 in the unblocked part, thus reducing the power generation efficiency. Setting the width of the baffle 15 to half the width of the through groove 4 can further increase the power generation efficiency.

[0032] Preferably, such as Figures 1 to 2As shown, the charging base body 1 has a beveled guide portion 14 at the upper end of the through groove 4, which makes the opening of the through groove 4 larger at one end and smaller at the other end, allowing more air or water to be introduced into the through groove 4 and forming a Bernoulli effect, further increasing the air or water flow rate.

[0033] Preferably, such as Figures 2 to 3 As shown, the cylindrical fan blade 5 includes a rotating column 18 and several square blades 19, which are evenly arranged around the rotating column 18.

[0034] Preferably, the charging base body 1 has a power-on button 6 installed at the bottom of the charging slot 2. A first micro switch is installed at the bottom of the power-on button 6. The micro switch can connect the power circuit and control the power-off and power-on of the first power-on contact 3. When the power-on button 6 is not pressed, the first power-on contact 3 is in the power-off state to prevent the charging base from short-circuiting when it is not charging. When charging, a rugged mobile phone is inserted into the charging slot 2. After the rugged mobile phone descends to the preset position, it comes into contact with the power-on button 6. Pressing the power-on button 6 connects the power supply and the circuit of the first power-on contact 3 to the first micro switch.

[0035] Preferably, such as Figure 4 As shown, an arc-shaped spring 24 is provided on one side of the battery compartment 22. One end of the arc-shaped spring 24 is fixedly connected to the side wall of the battery compartment 22. The battery compartment 22 is provided with a slot. The other end of the arc-shaped spring 24 is inserted into the slot and movably connected. A second micro switch is provided at the bottom of the slot. When the battery is inserted, the battery squeezes the arc-shaped spring 24, causing the arc-shaped spring 24 to insert into the bottom of the slot and press the second micro switch. The second micro switch can control the power connection and disconnection of the second power contact 23, which plays a foolproof role and prevents the second node contact from short-circuiting when the battery is not inserted.

[0036] Preferably, such as Figure 1 As shown, a fixing post 7 for tying ropes is fixedly provided on the upper end of the charging base body 1. A groove is provided in the middle of the fixing post 7 to facilitate fixing the ropes. The charging base is placed in the water flow to generate electricity.

[0037] Preferably, such as Figure 3 As shown, the charging base body 1 has an installation groove on one side corresponding to the rotating shaft of the cylindrical fan blade 5. The cylindrical fan blade 5 has rotating shafts at both ends, one of which extends into the installation groove and is rotatably connected to the charging base body 1. The rotating shaft of the cylindrical fan blade 5 is fixedly connected to a first gear 21 in the installation groove. A second gear 8 is installed in the installation groove. The first gear 21 and the second gear 8 mesh with each other. A rotating arm 9 is fixedly connected to the rotating shaft at the end of the second gear 8 away from the bottom of the installation groove. A crank 10 is rotatably connected to the end of the rotating arm 9 away from the second gear 8. By cranking the crank 10, the second gear 8 is rotated, which drives the first gear 21 to rotate, thereby generating electricity by hand.

[0038] Optionally, the diameter of the second gear 8 is greater than twice the diameter of the first gear 21, thereby increasing the rotational speed of the first gear 21 and further increasing the power generation efficiency of the hand-cranked generator.

[0039] Preferably, the rotating arm 9 has a through hole at the end away from the second gear 8, and the crank handle 10 is movably inserted into the through hole. Limiting blocks 20 are fixed at both ends of the crank handle 10. The charging base body 1 has a storage groove 11 at the bottom of the mounting groove for storing and hiding the crank handle 10. When manual power generation is not required, the crank handle 10 can be inserted into the storage groove 11 and fixed to hide the crank handle 10.

[0040] Preferably, the charging base has an arc-shaped guide portion 12 on the two sides facing the charging slot, which guides the airflow or water flow, further increasing the flow rate of the airflow or water flow and increasing the power generation efficiency.

[0041] Optionally, the charging base body 1 has a cover installed in the mounting slot. The cover is snapped into the charging base body 1. The charging base body 1 has a slot on the side wall of the mounting slot. An elastic snap-fit ​​member is fixedly connected to the side of the cover. When the cover is installed on the mounting slot, the elastic snap-fit ​​member is embedded in the slot and fixed.

[0042] Specifically, the working principle and usage process of this utility model are as follows: By installing a cylindrical fan blade 5 in the through groove 4 and then partially blocking the cylindrical fan blade 5 with a baffle 15, the cylindrical fan blade 5 can be rotated by water flow or natural wind, which drives the permanent magnet 17 on the rotating wheel 16 to rotate and generate a magnetic field change, thereby generating current in the conductive coil 13. The battery compartment 22 can be used to install a spare battery for a rugged phone to store the electrical energy generated by the conductive coil 13. After energy storage, it can be directly installed in the rugged phone for emergency power supply. The sealing cover 25 can seal the battery compartment 22 to prevent water from seeping in. It can be placed in a vertically flowing water stream and the water flow can be directed towards the cylindrical fan blade 5 to generate electricity. Alternatively, a rope can be tied to one end of the charging base and the charging base can be dropped into flowing water, and the water flow can impact the cylindrical fan blade 5 to rotate and generate electricity. The through groove 4 of the charging base can also be aligned with the direction of natural wind, and the natural wind can drive the cylindrical fan blade 5 to rotate and generate electricity.

[0043] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model.
