Description

Technical Field

[0001] The present invention belongs to the technical field of outdoor charging equipment for new energy vehicles, and in particular relates to an outdoor energy storage power supply device with a broadcasting function for new energy vehicles. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies and new structures. The outdoor energy storage and power supply device used for new energy vehicles is generally an integrated photovoltaic storage and charging vehicle charging station. The integrated photovoltaic storage and charging vehicle charging station is a new type of energy comprehensive utilization system that combines photovoltaic power generation, energy storage system and electric vehicle charging facilities. For example, the patent authorization announcement number is CN215793241U, which discloses an urban integrated photovoltaic storage and charging vehicle charging station.

[0003] At present, new energy vehicle drivers generally have mileage anxiety and charging anxiety while driving. Therefore, the existing outdoor energy storage power supply devices have two modes: fast charging and normal charging. The fast charging mode shortens the charging time by increasing the charging current and voltage. However, in the fast charging mode of the outdoor energy storage power supply device, the current passing through the charging plug in a short period of time is too large, which will cause overheating at the charging plug. Therefore, the charging plugs of the outdoor energy storage power supply devices are currently equipped with thermal management chips. The chip avoids continuous overheating by reducing the current passing through the charging plug. However, this overheating regulation method will affect the charging efficiency of the outdoor energy storage power supply device for new energy vehicles, and thus affect the use effect of the outdoor energy storage power supply device.

[0004] In addition, the existing outdoor energy storage power supply device does not have the function of reminding the driver to wipe foreign matter or water stains on the surface of the charging plug, which causes the driver to easily ignore the interference of impurities or water stains attached to the surface of the charging plug when charging the new energy vehicle through the charging plug. Impurities entering the charging port can easily cause poor contact, and water stains can easily cause a short circuit at the charging interface, which not only affects the reliability of the outdoor energy storage power supply device for charging new energy vehicles, but also affects the safety of its charging.

[0005] To this end, we propose an outdoor energy storage power supply device with broadcasting function for new energy vehicles to solve the above problems. Summary of the invention

[0018] Compared with the existing technology, the advantages of an outdoor energy storage power supply device with broadcasting function for new energy vehicles are:

[0019] 1. Through the parking mechanism, loudspeaker, storage and double-control switch, when the new energy vehicle needs to be quickly charged through the outdoor energy storage power supply device, the parking posture of the new energy vehicle can be corrected through the parking mechanism first, to ensure that the posture of the new energy vehicle parked in the charging parking space will not interfere with the parking of other vehicles in the surrounding charging parking spaces, and the loudspeaker broadcasts a voice reminder when the parking posture is not standard, and when the new energy vehicle is charged through the charging plug, the loudspeaker plays a voice message to remind the driver to wipe the impurities and water stains attached to the surface of the charging plug through the double-control switch, to avoid impurities entering the charging port to cause poor contact, and water stains to cause a short circuit at the charging interface. This mechanism enables the outdoor energy storage power supply device to have the voice broadcast reminder function of wiping the attachments on the surface of the charging plug and the improper parking posture of the new energy vehicle, thereby improving the reliability and safety of the outdoor energy storage power supply device for charging new energy vehicles.

[0020] 2. Through the protection mechanism and limit mechanism, when the charging plug is inserted into the charging interface of the new energy vehicle, the negative pressure suction cup is firstly contacted with the surface of the new energy vehicle, and then the staff needs to press the limit button of the charging plug again so that the charging plug can be smoothly inserted into the charging interface of the new energy vehicle. During the pressing of the limit button, the driver will simultaneously press another switch button of the double-control switch, and then the switch button sends an electrical signal to the microcontroller through the double-control switch. The microcontroller energizes the three-way reversing solenoid valve and the vacuum pump for 10 seconds according to the electrical signal. During the 10 seconds, the vacuum pump makes the limit mechanism tightly absorb the surface of the new energy vehicle to ensure that the limit mechanism can assist in supporting the charging plug. During the insertion process of the charging plug, the charging interface of the new energy vehicle pushes the hollow cylinder to move, so that the hollow cylinder carries the sealing moving ring close to the damping rubber sleeve, and at the same time makes the hollow cylinder located at the charging port for protection. This mechanism enables the outdoor energy storage power supply device to have the function of auxiliary support, so as to avoid the plug-in end of the charging plug being damaged by its own weight, and at the same time can improve the stability and safety of the outdoor energy storage power supply device charging the new energy vehicle.

[0021] 3. Through the provided cold and hot regulating mechanism and temperature sensor, when the temperature sensor detects that a high temperature environment is formed at the charging plug, the cold and hot regulating mechanism promptly delivers low-temperature air to the protective mechanism, and uses the low-temperature air to accelerate the cooling of the charging plug. In addition, the charging plug does not need to adjust the current passing through the charging plug in the outdoor energy storage power supply device through the thermal management chip, so as to ensure that the outdoor energy storage power supply device can continuously and quickly charge the new energy vehicle. When the new energy vehicle is charged in a sub-zero low temperature environment, especially when the charging plug is not unplugged after charging is completed, the temperature sensor delivers a low-temperature electrical signal to the microcontroller. If the temperature is lower than the low-temperature threshold preset by the microcontroller, The microcontroller then controls the hot and cold regulating mechanism to generate hot air and transmit it to the charging plug. The heat of the hot air is used to prevent the charging plug from freezing and to prevent the charging plug from being inconvenient to unplug due to freezing. This mechanism enables the charging plug of the outdoor energy storage power supply device to have the function of automatic hot and cold regulation, and improves the protection capability of the charging plug of the device. It can not only prevent the charging plug from continuously overheating and causing a decrease in charging efficiency, but also prevent the charging plug from being frozen by a low temperature environment, thereby ensuring the charging efficiency of the outdoor energy storage power supply device for new energy vehicles and improving the use effect of the outdoor energy storage power supply device.

The two ends of the spring 20 are respectively fixedly connected with the inner wall of the guide cylinder 62 and the outer wall of the sealing ring 64. The elastic force of the spring 20 can push the moving tube 63 to move outward, so that the negative pressure suction cup 65 can be close to the surface of the new energy vehicle.

[0032] A connection cover 14 and a microcontroller 15 are fixedly connected to the upper surface of the shell of the main body 1 of the outdoor energy storage power supply device, a through hole is provided on the side wall of the connection cover 14, and a speaker 16 is fixedly connected to the hole wall of the through hole, a storage device 17 for broadcast voice storage is fixedly connected to the top inner wall of the connection cover 14, a rectangular through hole is provided on the upper surface of the connection cover 14, and a cold and heat regulating mechanism 7 is fixedly connected to the hole wall of the rectangular through hole, and the cold and heat regulating mechanism 7 includes a heat insulation box 71 fixedly connected to the connection cover 14, a plurality of fixed through holes are provided on the upper surface of the heat insulation box 71, and a semiconductor refrigeration sheet 72 is fixedly connected to the hole wall of the fixed through hole, a plurality of metal mesh plates 73 are fixedly connected to the cooling side of the plurality of semiconductor refrigeration sheets 72, and a heat dissipation sheet 74 is fixedly connected to the heat dissipation side of the plurality of semiconductor refrigeration sheets 72, an electric heating tube 75 is fixedly connected to the side wall of the heat insulation box 71, and the heating end of the electric heating tube 75 passes through a plurality of metal mesh plates 73, and an air pump 76 is fixedly connected to the upper surface of the main body 1 of the outdoor energy storage power supply device, and the air pump The air inlet end of the air pump 76 is fixedly connected with an air suction pipe 77, the air inlet end of the air suction pipe 77 passes through the connecting cover 14 and is fixedly connected with the air outlet end of the three-way reversing solenoid valve 66, the air outlet end of the air pump 76 is fixedly connected with the upper surface of the heat insulation box 71 through the connecting pipe, the lower surface of the heat insulation box 71 is fixedly connected with an air outlet pipe 78, the air outlet end of the air outlet pipe 78 passes through the outer wall of the connecting cover 14 and is fixedly connected with the outer wall of the hollow cylinder 51, the air outlet end of the air outlet pipe 78 is connected with the cavity of the hollow cylinder 51, and the heat insulation box 7 1 is fixedly connected with a normally open electromagnetic valve 79, and the walls of the air intake pipe 77 and the air outlet pipe 78 are fixedly connected to the outer wall of the data line of the charging plug 2, thereby improving the cleanliness of the air intake pipe 77 and the air outlet pipe 78.

[0033] Two positioning ropes 18 are fixedly connected to the outer wall of the bottom end of the main body 1 of the outdoor energy storage and power supply device, and the side ends of the two positioning ropes 18 are fixedly connected to a fixed bottom plate 19. The upper surface of the fixed bottom plate 19 is fixedly connected to a parking mechanism 8 for wheel blocking. The parking mechanism 8 includes two hollow car-blocking blocks 81 fixedly connected to the upper surface of the fixed bottom plate 19. An air pressure sensor 82 is provided inside the hollow car-blocking block 81. The bottom end of the air pressure sensor 82 is fixedly connected to the upper surface of the fixed bottom plate 19. An air hole 83 is opened on the outer wall of the hollow car-blocking block 81. An arc-shaped rubber cover 84 is fixedly connected to the outer wall of the hollow car-blocking block 81 on one side of the air hole 83. This mechanism can correct the parking posture of the new energy vehicle in the charging parking space, avoid the tilt of the vehicle body from interfering with other vehicles parked in the surrounding charging parking spaces, and protect the main body 1 of the outdoor energy storage and power supply device.

[0034] The temperature sensor 4 and the two air pressure sensors 82 are electrically connected to the input end of the microcontroller 15 through wires, the three-way reversing solenoid valve 66, the double-control switch 67, the semiconductor refrigeration plate 72, the electric heating tube 75, the vacuum pump 76 and the normally open solenoid valve 79 are electrically connected through the output end of the microcontroller 15, and the speaker 16 and the storage 17 are also electrically connected to the microcontroller 15. The model of the microcontroller 15 is an Arduino Uno type controller. The above-mentioned power-on devices and electrical connections are all existing technologies and will not be repeated here.

[0035] The operating principle of the present invention is described as follows: when the new energy vehicle needs to be quickly charged through the outdoor energy storage power supply device, the driver first parks the new energy vehicle in the charging parking space, and then the fixed bottom plate 19 and the hollow block 81 arranged on the front side of the main body 1 of the outdoor energy storage power supply device can prevent the new energy vehicle from getting too close and causing collision accidents. At the same time, if the new energy vehicle parked in the charging parking space is tilted and easily interferes with other new energy vehicles parked in the surrounding charging parking spaces, due to the tilted posture of the new energy vehicle body, only one rear wheel of the new energy vehicle will squeeze the arc-shaped rubber cover 84 on the hollow block 81. The arc-shaped rubber cover 84 is deformed so that the air inside it enters the hollow block 81 through the air vent 83, and the air pressure in the hollow block 81 is increased. The air pressure sensor 82 transmits the pressure data to the microcontroller 15, and the air pressure sensor 82 detects the air pressure. After the pressure reaches the preset air pressure threshold of the microcontroller 15, the microcontroller 15 broadcasts the car posture adjustment reminder voice information pre-stored in the storage 17 through the speaker 16, reminding the driver to adjust the posture of the new energy vehicle in time, and make the two rear wheels of the car close to the parking mechanism 8, so as to avoid the new energy vehicle being far away from the parking mechanism 8 and causing the charging port of the new energy vehicle to be too far away from the charging plug 2 and unable to charge. In addition, when the new energy vehicle approaches the parking mechanism 8 in a correct posture, the two rear wheels of the new energy vehicle simultaneously make the air pressure sensors 82 in the two hollow blocks 81 of the car block affected by the increased air pressure, and then send an electrical signal to the microcontroller 15 at the same time. At this time, the microcontroller 15 does not control the speaker 16 to play the car posture adjustment reminder voice information pre-stored in the storage 17, and then the driver gets off the car and performs a fast charging operation on the new energy vehicle through the outdoor energy storage power supply device main body 1 and the charging plug 2;

[0036] When the driver takes out the charging plug 2 from the main body 1 of the outdoor energy storage power supply device to charge the new energy vehicle, the driver needs to press the upper limit button on the charging plug 2 to unlock it for easy removal of the charging plug 2. While pressing the limit button, the driver will press the dual-control switch 67. After one switch button of the dual-control switch 67 is pressed, the dual-control switch 67 circuit will send an electrical signal to the input end of the microcontroller 15. The microcontroller 15 makes the speaker 16 play the voice information pre-stored in the storage 17 to remind the driver to wipe the impurities and water stains attached to the surface of the charging plug 2 according to the signal, so as to avoid the impurities entering the charging port to cause poor contact and the water stains to cause a short circuit at the charging interface. This mechanism enables the outdoor energy storage power supply device to have the voice broadcast reminder function of wiping the attached objects on the surface of the charging plug 2 and the improper parking posture of the new energy vehicle, thereby improving the reliability and safety of the outdoor energy storage power supply device for charging new energy vehicles.

[0037] When the charging plug 2 is inserted into the charging interface of the new energy vehicle, the negative pressure suction cup 65 is firstly made to contact the surface of the new energy vehicle, and then the staff needs to press the limit button of the charging plug 2 again so that the charging plug 2 can be smoothly inserted into the charging interface of the new energy vehicle. During the pressing of the limit button, the driver will simultaneously press another switch button of the double-control switch 67, and then the switch button sends an electrical signal to the microcontroller 15 through the double-control switch 67. The microcontroller 15 energizes the three-way reversing solenoid valve 66 and the vacuum pump 76 for 10 seconds according to the electrical signal. During the 10-second period, the vacuum pump 76 sucks the air in the guide cylinder 62 through the suction pipe 77, and the guide cylinder 62 sucks the air in the negative pressure suction cup 65 through the moving pipe 63, so that the negative pressure suction cup 65 is tightly adsorbed on the surface of the new energy vehicle, and the moving pipe 63 will be contracted as much as possible after the gas in the air guide cylinder is extracted, so as to ensure that the limit mechanism 6 can assist The auxiliary support of the charging plug 2 enables the charging plug 2 to be supported at two points when charging the new energy vehicle, thereby preventing the entire weight of the charging plug 2 from acting on the charging interface of the new energy vehicle, and further preventing the plug-in end of the charging plug 2 from being damaged by its own weight. During the insertion process of the charging plug 2, the charging interface of the new energy vehicle pushes the hollow cylinder 51 to move, so that the hollow cylinder 51 carries the sealing movable ring 13 close to the damping rubber sleeve 11, and the damping rubber sleeve 11 contacts the sealing movable ring 13. The friction between the two can effectively improve the stability of the position of the hollow cylinder 51, and the hollow cylinder 51 can ensure the sealing of the side end connection through the protective rubber ring 9. This mechanism enables the outdoor energy storage power supply device to have the function of auxiliary support, thereby preventing the plug-in end of the charging plug 2 from being damaged by its own weight, and at the same time can improve the stability and safety of the outdoor energy storage power supply device charging the new energy vehicle.

[0038] When the outdoor energy storage power supply device quickly charges the new energy vehicle and causes the charging plug 2 to overheat, the temperature sensor 4 detects the internal temperature of the charging plug 2 in real time and sends a temperature electrical signal to the microcontroller 15. If the temperature inside the charging plug 2 exceeds the temperature threshold preset by the microcontroller 15, the microcontroller 15 controls the semiconductor refrigeration plate 72, the normally open solenoid valve 79 and the vacuum pump 76 to work. The vacuum pump 76 draws in the outside air through the suction pipe 77 and the three-way reversing solenoid valve 66 that is not powered to change the air guide direction. Then the outside air enters the heat insulation box 71. After the semiconductor refrigeration plate 72 is powered on and started, the cooling layer will reduce the insulation through the metal mesh plate 73. The temperature in the heat box 71 can reduce the temperature of the outside air input by the vacuum pump 76. At this time, the normally open solenoid valve 79 is energized and closed, and the low-temperature air in the heat insulation box 71 is transported to the hollow cylinder 51 through the outlet pipe 78. Then, the low-temperature air in the hollow cylinder 51 is sprayed to the surface of the charging plug 2 through the one-way air nozzle 52 for heat dissipation. Then, the heat-dissipated air is discharged through the exhaust one-way valve 53. The low-temperature air can prevent the charging plug 2 from continuously overheating, and the charging plug 2 does not need to adjust the current passing through the charging plug 2 in the outdoor energy storage power supply device through the thermal management chip, so as to ensure that the outdoor energy storage power supply device can continuously and quickly charge the new energy vehicle.

[0039] If the new energy vehicle is charging in a sub-zero low temperature environment, especially when the charging plug 2 is not unplugged after charging is completed, the temperature sensor 4 transmits a low-temperature electrical signal to the microcontroller 15. If the temperature is lower than the low-temperature threshold preset by the microcontroller 15, the microcontroller 15 controls the electric heating tube 75, the normally open solenoid valve 79 and the vacuum pump 76 to work. The vacuum pump 76 draws outside air through the suction pipe 77 and the three-way reversing solenoid valve 66 that is not powered to change the air guide direction, and then the outside air enters the heat insulation box 71. After the electric heating tube 75 is powered on and started, the temperature in the heat insulation box 71 can be increased through the metal mesh plate 73, thereby increasing the temperature of the outside air input by the vacuum pump 76. At this time, the normally open solenoid valve 79 is powered on and closed, and the hot air in the heat insulation box 71 is transported to the hollow cylinder 51 through the outlet pipe 78. Then the hot air in the hollow cylinder 51 is sprayed onto the surface of the charging plug 2 through the one-way air nozzle 52 for heating, and then the heated air is discharged through the exhaust one-way valve 53, so as to further increase the temperature near the charging plug 2, avoid the moisture in the air from condensing into ice on the surface of the charging plug 2 in a low temperature environment, and avoid the situation where the charging plug 2 is frozen and inconvenient to be unplugged. This mechanism enables the charging plug 2 of the outdoor energy storage power supply device to have the function of automatic hot and cold adjustment, and improves the protection ability of the charging plug 2 of the device, which can not only avoid the situation where the charging plug 2 is continuously overheated and causes a decrease in charging efficiency, but also avoid the situation where the charging plug 2 is frozen in a low temperature environment, thereby ensuring the charging efficiency of the outdoor energy storage power supply device for new energy vehicles, and improving the use effect of the outdoor energy storage power supply device.
