A portable intelligent charger

Abstract

The present application discloses a portable intelligent charger, which is placed in a wrapping groove so that the charger squeezes the elastic rubber layer under its own weight and transmits the squeezing force to the cooling liquid in the liquid storage chamber, so that the cooling liquid flows to the part not squeezed by the charger until the charger is completely wrapped in the wrapping groove. At this time, because the top of the elastic rubber layer is not directly squeezed by the charger, a part of the cooling liquid flows upward there, causing the elastic rubber layer here to expand and wrap around the top side of the charger, directly wrapping the entire charger on three side walls, the top side and the bottom, so that external vibration needs to be transmitted to the external outer frame first and then to the charger. At this time, the vibration of the charger will be transmitted to the elastic rubber layer, which will be buffered and protected by the cooling liquid, thereby reducing the damage caused by external vibration to the charger.

[0002] With the rapid development of science and technology, portable charging equipment is increasingly used in various fields, especially in the fields of electricity, communications, transportation and new energy, and its importance is becoming more and more prominent. As an efficient and convenient charging solution, portable chargers not only meet the charging needs of various devices in mobile or emergency situations, but also greatly improve work efficiency and user experience.

[0003] Portable chargers need to be carried by users and are generally placed directly in the trunk of a vehicle, which can easily cause the vehicle to transmit vibrations to the portable charger when passing over bumpy roads. Especially when traveling outdoors, such bumps are particularly severe, resulting in excessive impact force on the portable charger, which can easily cause the battery pack and electronic components inside the portable charger to fall off and be damaged. At the same time, most existing portable chargers use fans to provide air cooling to the electronic components inside the charger. In the face of harsh outdoor environments, this will undoubtedly cause a large amount of impurities to follow the airflow provided by the fan into the charger, damaging the electronic components. Summary of the invention

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a portable intelligent charger, comprising a charger, wherein a circulating pump and a connected cooling pipe are arranged inside the charger, and a connection port I and a connection port II respectively connected to the circulating pump and the cooling pipe are arranged at the top of the charger; an outer casing is arranged on the outside of the charger, the top of the outer casing is open, an elastic rubber layer is arranged on the edge of the inner side wall of the outer casing, a liquid storage cavity is formed between the elastic rubber layer and the outer casing, the liquid storage cavity is filled with cooling liquid, the elastic rubber layer forms a wrapping groove away from the inner side of the outer casing, and the charger is sleeved on The wrapping groove is used to wrap and protect the charger and buffer the vibration of the charger through cooling liquid; a connecting hose I and a connecting hose II are arranged on the top of the outer casing, and a flexible joint is arranged on the end of the connecting hose I and the connecting hose II away from the outer casing. The connecting hose I is connected to the connecting port I through the flexible joint, and the connecting hose II is connected to the connecting port II through the flexible joint, which is used for circulating cooling liquid; uniformly distributed heat dissipation fins are arranged on the outer side wall of the outer casing, and a fan sleeve is arranged on one side of the outer casing, and a fan is arranged in the fan sleeve for heat dissipation of the cooling liquid.

[0006] Preferably, the side of the charger is provided with a rounded surface to prevent the hard edges of the charger from cutting the elastic rubber layer.

[0007] Preferably, the connection port I is connected to the input end of the circulation pump, one end opening of the cooling pipe is connected to the output end of the circulation pump, and the connection port II is connected to the other end opening of the cooling pipe.

[0008] Preferably, the heat dissipation fins between the fan sleeve and the outer casing are in contact with an end of the fan sleeve facing the outer casing, thereby providing space for the cooling airflow to flow.

[0009] Preferably, evenly distributed fixing rods are provided on the outer wall of the fan, and one end of the fixing rods away from the fan is connected to the inner wall of the fan sleeve for fixing the position of the fan, and a protective mesh plate is bolted to one end of the fan sleeve away from the outer frame.

[0010] Preferably, the connection port I and the connection hose I are both far away from the fan sleeve, and the connection port II and the connection hose II are both close to the fan sleeve, so as to extend the flow path of the cooling liquid.

[0011] Preferably, a uniformly distributed limiting cylinder is provided at the center of the inner bottom end of the outer casing, a pull rope is sleeved inside the limiting cylinder, both ends of the pull rope are connected to a buoyancy ball, and the buoyancy ball is located at the top of the liquid storage cavity, so as to improve the ability of the elastic rubber layer to wrap the charger.

[0012] The present application provides a portable intelligent charger, which places the charger in a wrapping groove so that the charger squeezes the elastic rubber layer under its own weight and transmits the squeezing force to the cooling liquid in the liquid storage chamber, so that the cooling liquid surges to the part not squeezed by the charger until the charger is completely wrapped in the wrapping groove. At this time, because the top of the elastic rubber layer is not directly squeezed by the charger, a part of the cooling liquid surges upward there, causing the elastic rubber layer here to expand and wrap around the top side of the charger, directly wrapping the entire charger on three side walls, top side and bottom, so that external vibration needs to be transmitted to the external outer frame first and then to the charger. At this time, the vibration of the charger will be transmitted to the elastic rubber layer, which will be buffered and protected by the cooling liquid, thereby reducing the damage caused by external vibration to the charger.

[0013] At the same time, the charger is equipped with a circulating pump. When the circulating pump is started, it will draw cooling liquid into the cooling pipe laid in the charger to cool the battery packs and electronic components arranged around the cooling pipe and other devices that need cooling. Then the cooling liquid after absorbing heat will flow back to the liquid storage chamber again, and dissipate the heat through the cooling fins and the airflow output by the fan. Most of the heat dissipated in the charger will also be transferred to the contacting elastic rubber layer through the charger casing, and then to the cooling liquid in the liquid storage chamber, thereby maintaining the temperature of the charger during operation.

[0014] At the same time, since the charger is wrapped in the wrapping groove formed by the cooling liquid and the elastic rubber layer, the charger is not stable due to the fluidity of the cooling liquid and the deformability of the elastic rubber layer. There will be a lot of room for movement. When the charger is started, the vibration of the internal motor will cause the unstable charger to vibrate. This vibration will be transmitted to the cooling liquid in the liquid storage chamber through the elastic rubber layer, causing the cooling liquid to fluctuate under the vibration force, thereby increasing the turbulence effect, increasing the contact time between different cooling liquids and the side wall of the outer casing per unit time, and improving the heat dissipation effect through the heat dissipation fins.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] Embodiment 1

[0027] See also Figure 1 to Figure 2 , including a charger 1, wherein a conventional intelligent control device, a battery pack and various electronic components are arranged in the charger 1, a circulating pump is arranged in the charger 1, a cooling pipe is laid in the charger 1, the cooling pipe is in contact with the components to be cooled in the charger 1, a connection port Ⅰ2 and a connection port Ⅱ21 are fixedly connected to the top of the charger 1, the connection port Ⅰ2 is connected to the input end of the circulating pump, one end opening of the cooling pipe is connected to the output end of the circulating pump, and the connection port Ⅱ21 is connected to the other end opening of the cooling pipe, so that the charger When starting, the intelligent control device can start the circulation pump, so that the circulation pump can draw cooling liquid into the cooling pipe through the connection port Ⅰ2, cool the heat source in the charger 1, and then discharge the heat-absorbing cooling liquid back to the liquid storage chamber 6 through the connection port Ⅱ21. The side of the charger 1 is provided with a rounded surface, so that when the charger 1 is placed in the wrapping groove 51 and contacts the elastic rubber layer 5, the side of the charger 1 has no hard edges and corners to cut the elastic rubber layer 5, thereby avoiding the problem of the elastic rubber layer 5 being cut and damaged under the hard edges and corners.

[0028] See also Figure 1 , Figure 3 to Figure 4 , an outer jacket frame 3 is provided on the outside of the charger 1, and the top and one side of the outer jacket frame 3 are open. Two symmetrical L-shaped baffles 31 are fixedly connected to the side opening of the outer jacket frame 3, and one side of the L-shaped baffle 31 contacts the end of the charger 1 protruding from the side opening of the outer jacket frame 3, so that the charger 1 can be placed in the wrapping groove 51 through the opening at the top of the outer jacket frame 3, and the side of the charger 1 provided with an operation interface and a plug interface can protrude through the side opening of the outer jacket frame 3, so that the user can use the charger 1 through the protruding operation interface and the plug interface, and the L-shaped baffle 31 will prevent the charger 1 from sliding out of the side opening of the outer jacket frame 3. It should be noted that the operation interface and the plug interface of the charger 1 can be set at the top of the charger 1. At this time, the outer jacket frame 3 only needs to be opened at the top, and the four inner side walls of the outer jacket frame 3 will be in a closed device at this time, and the elastic rubber layer 5 will also be wrapped on the four inner side walls and the bottom of the outer jacket frame 3 to more comprehensively wrap the placed charger 1.

[0029] See also Figure 1 , Figure 3 to Figure 4 , Figure 6 An elastic rubber layer 5 is fixedly connected to the edge of the inner wall of the outer casing 3, and a liquid storage chamber 6 is formed between the elastic rubber layer 5 and the outer casing 3. The liquid storage chamber 6 is filled with cooling liquid. The material of the cooling liquid can be selected according to actual needs. The elastic rubber layer 5 forms a wrapping groove 51 on the inner side away from the outer casing 3. The charger 1 is movably sleeved in the wrapping groove 51. When the charger 1 is placed in the wrapping groove 51, the charger 1 will squeeze the elastic rubber layer 5 under its own weight, and transmit the squeezing force to the cooling liquid in the liquid storage chamber 6, so that the cooling liquid surges to the part that is not squeezed by the charger 1 until the charger 1 is completely wrapped in the wrapping groove. At this time, the top of the elastic rubber layer 5 is not directly squeezed by the charger 1, so that part of the cooling liquid is The elastic rubber layer 5 here surges upward to this point, causing it to expand and wrap around the top side of the charger 1, directly wrapping the entire charger 1 on three side walls, the top side, and the bottom (for the outer jacket frame 3 with openings on the sides and the top in this application, if it is the outer jacket frame 3 with only the top opening, the wrapping state will be changed to direct wrapping on four side walls, the top side, and the bottom), so that the external vibration needs to be transmitted to the external outer jacket frame 3 first and then to the charger 1. At this time, the vibration of the charger 1 will be transmitted to the elastic rubber layer 5 and absorbed by the cooling liquid for buffering protection, thereby reducing the vibration damage to the charger 1 due to bumps, and most of the noise generated by the charger 1 after starting will also be reduced by the cooling liquid.

[0030] See also Figures 1 to 4 , Figure 6A connecting hose I7 and a connecting hose II71 are fixedly connected to the top of the outer casing 3, and both the connecting hose I7 and the connecting hose II71 are connected to the liquid storage chamber 6. The ends of the connecting hose I7 and the connecting hose II71 away from the outer casing 3 are movably connected with a flexible joint 8. The connecting hose I7 is threadedly fixedly connected to the connecting port I2 through the flexible joint 8, and the connecting hose II71 is threadedly fixedly connected to the connecting port II21 through the flexible joint 8, so that after the charger 1 is placed in the packaging groove 51, the connecting hose I7 and the connecting port I2 can be connected through the flexible joint 8, and the connecting hose II71 and the connecting port II21 can be connected through the flexible joint 8. At this time, when the circulating pump is started, the cooling liquid in the liquid storage chamber 6 can be extracted through the connecting hose I7, and the cooling liquid after absorbing heat is returned to the liquid storage chamber 6 through the connecting hose II71. At this time, the cooling liquid in the liquid storage chamber 6 will flow from the direction of the connecting hose II71 to the direction of the connecting hose I7.

[0031] See also Figure 1 , Figures 3 to 5 , the outer wall of the outer casing 3 is fixedly connected with uniformly distributed heat dissipation fins 4, so that the heat-absorbing cooling liquid refluxed into the liquid storage chamber 6 can exchange heat with the outside through the heat dissipation fins 4 for cooling treatment, and the side of the outer casing 3 away from the side opening is fixedly connected with a fan sleeve 9 by bolts, and the heat dissipation fins 4 between the fan sleeve 9 and the outer casing 3 are in contact with the end of the fan sleeve 9 facing the outer casing 3, and a fan 10 is arranged in the fan sleeve 9, and uniformly distributed fixing rods 91 are fixedly fixed with bolts on the outer wall of the fan 10, and the end of the fixing rod 91 away from the fan 10 It is welded to the inner wall of the fan sleeve 9 so that when the fan 10 is started, a cooling airflow will be delivered to the end of the outer casing 3 facing the fan 10, so that the heat dissipation fins 4 of this part can obtain a more efficient cooling effect. At this time, the cooling airflow will be discharged from the top or bottom through the intervals between the heat dissipation fins 4, forming an airflow flow state, maintaining the fan 10 in a state of continuously inputting new cooling airflow. A protective mesh plate 11 is bolted to the end of the fan sleeve 9 away from the outer casing 3 to prevent large particles of impurities from directly entering the fan sleeve 9 and causing damage to the fan 10.

[0032] See also Figures 1 to 4 , Figure 6, the connection port Ⅰ2 and the connection hose Ⅰ7 are both close to the side opening of the outer casing 3, and the connection port Ⅱ21 and the connection hose Ⅱ71 are both close to the fan sleeve 9, so that the cooling liquid after absorbing heat is in a direction away from the connection hose Ⅰ7 and close to the fan 10 after returning to the liquid storage chamber 6. At this time, the temperature of the input heat-absorbing cooling liquid is the highest, and the heat dissipation effect on the side where the fan 10 and the heat dissipation fins 4 exist is the best, so that the returned heat-absorbing cooling liquid can dissipate heat efficiently and then flow in the direction of the connection hose Ⅰ7. At this time, the flowing cooling liquid will continue to dissipate heat through the side heat dissipation fins 4, resulting in the cooling liquid being able to obtain a long-term It is important to note that since the charger 1 is wrapped in the wrapping groove 51 formed by the cooling liquid and the elastic rubber layer 5, the charger 1 is not stable due to the fluidity of the cooling liquid and the deformability of the elastic rubber layer 5. There will be a lot of room for movement. When the charger 1 is started, the vibration of the internal motor will cause the unstable charger 1 to shake. This shaking will be transmitted to the cooling liquid in the liquid storage chamber 6 through the elastic rubber layer 5, causing the cooling liquid to fluctuate under the vibration force, thereby improving the turbulence effect, increasing the contact time between different cooling liquids and the side wall of the outer casing 3 per unit time, and improving the heat dissipation effect through the heat dissipation fins 4.

[0033] Embodiment 2

[0034] See also Figure 7On the basis of the first embodiment, the center of the inner bottom end of the outer casing 3 is fixedly connected with a limiting cylinder 12 which is evenly distributed in a straight line in the long side direction, and a pull rope 13 is movably sleeved in the limiting cylinder 12, so that the pull rope 13 can reciprocate in the limiting cylinder 12, and both ends of the pull rope 13 are fixedly connected with a buoyancy ball 14, and the buoyancy ball 14 is located at the top of the liquid storage chamber 6. Under the buoyancy of the cooling liquid, all the buoyancy balls 14 can move upward to straighten the pull rope 13. When the charger 1 is placed in the package slot 51 When the cooling liquid is squeezed, the cooling liquid surging upward will drive all the buoyancy balls 14 to move upward, so that many of the buoyancy balls 14 are stuck on the top side of the charger 1. At this time, the pull rope 13 will be squeezed on the side wall of the charger 1 following the elastic rubber layer 5 due to the pulling force of the buoyancy balls 14 on both sides and the position limitation of the limit tube 12. When the charger 1 is shaking, this shaking will directly affect the contacting pull rope 13, so that the pull rope 13 pulls the buoyancy ball 14 to shake, stirring the surrounding coolant , further improving the turbulence effect, thereby improving the heat dissipation effect. At the same time, it should be noted that when the charger 1 shakes to one side, an extrusion force will be applied to the elastic rubber layer 5 and the pull rope 13 on this side, while the elastic rubber layer 5 and the pull rope 13 on the other side will temporarily lose the extrusion force, and the elastic rubber layer 5 and the pull rope 13 on the squeezed side will apply tension, so that the elastic rubber layer 5 and the pull rope 13 that temporarily lose the extrusion force still contact the other side of the charger 1 under tension, and the tension of the pull rope 13 will cause the pull rope 13 to be pulled toward the shaking side of the charger 1. At this time, the buoyancy ball 14 on the other side that is subjected to tension will be tightly buckled on the top side of the charger 1, so that the charger 1 is always wrapped by the elastic rubber layer 5, especially when the charger 1 and the outer casing 3 tip over to one side, in this movement state of the elastic rubber layer 5 and the pull rope 13, the charger 1 can still be temporarily wrapped in the elastic rubber layer 5, so as to avoid the charger 1 being directly thrown out from the top opening of the outer casing 3 when tipping over, causing collision damage.
