Description

Technical Field

[0001] The present invention relates to the technical field of outdoor charging piles, and in particular to an anti-collision intelligent outdoor charging pile for new energy vehicles and a method thereof. Background Art

[0002] The emergence of smart charging piles is an inevitable product of the development of new energy vehicle technology. It integrates advanced technologies such as the Internet of Things, big data, and cloud computing, and realizes the intelligent, automated, and remote management of the charging process. Through intelligent identification, precise control, multiple protections and other functions, smart charging piles provide electric vehicle users with an unprecedented charging experience. This technological innovation not only improves charging efficiency and reduces charging costs, but also invisibly promotes changes in travel methods.

[0003] With the help of big data and cloud computing technology, the smart charging pile system can intelligently recommend the best charging station and charging time based on the user's travel route, vehicle type, battery status and other information. This not only helps users save time in finding charging stations, but also avoids travel delays caused by inconvenient charging.

[0004] With the continuous development and popularization of smart charging pile technology, the future travel mode will be more intelligent, convenient and green. On the one hand, smart charging piles will be deeply integrated with other intelligent transportation facilities such as intelligent road networks and autonomous driving technologies to form a more complete smart travel ecosystem. In this ecosystem, various links such as vehicles, roads, and charging facilities will achieve information exchange and collaborative work, providing users with a more efficient, convenient and safe travel experience.

[0005] On the other hand, with the continuous expansion of the new energy vehicle market and the continuous improvement of the smart charging pile network, the future travel mode will be more low-carbon, environmentally friendly and sustainable. Smart charging piles will serve as a bridge connecting energy production and consumption, promoting the optimization and upgrading of energy structure; at the same time, through intelligent management and service means, it will reduce energy consumption and carbon emissions and contribute to the sustainable development of the earth.

[0006] Although new energy vehicles have been used for many years, they are still considered a new thing. After the charging piles are installed and put into operation, user information needs to be collected and analyzed, and then the feedback is optimized. Among them, vehicle manufacturers and battery manufacturers have more feedback, mainly focusing on four issues: 1) The battery life of new energy electric vehicles is relatively short.

[0007] 2) When using a charging station for charging, it usually takes a long time to fully charge the battery.

[0008] 3) The coverage of charging pile facilities urgently needs to be further expanded. Currently, there is a clear problem of insufficient quantity and inability to meet market demand.

[0009] 4) Hidden dangers in the installation specifications of charging piles have not been properly addressed.

[0010] Safety regulations are crucial when installing charging piles. Since charging piles are potentially risky, any installation defects may lead to serious consequences. For example, high voltage may pose a threat to users; poor grounding may cause electric shock; if the charging gun plug is not locked and the electronic lock device is not installed, the user will still be charged when using the charging plug, which is extremely dangerous; improper installation during the installation of the charging pile (such as poor sealing and failure to waterproof) may cause short circuits and electric shock accidents. Therefore, strict regulations must be followed during the installation process to ensure the safety of staff and users. The installation site may be affected by weather such as rain, and a rain shelter must be built to protect the safety of equipment and personnel. All installation and maintenance work should be supervised to enhance the sense of responsibility and technical level of staff, and regular training is also necessary to improve the quality and safety of installation.

[0011] For example, application number 202111200433.8 discloses an anti-collision structure and a charging pile with the structure, which relates to the field of charging piles, including: a charging body, a protective part, and a rain shield part. When the charging pile is hit by a vehicle or other factors, the protective plate of the protective device is hit first to prevent damage to the surface of the charging pile, and then cooperates with the first protective spring to apply a reverse force to the protective plate to further reduce the impact force on the protective plate. When the charging pile collapses due to excessive collision force, the second protective spring and the first protective spring support the protective plate to prevent the charging pile from being damaged after falling to the ground.

[0012] However, most of the current charging piles have hard contact caused by charging pile collisions, which leads to deformation and damage of the charging piles and irreversible damage to the components inside the distribution cabinet due to hard contact collisions. The degree of damage to the components during the collision cannot be reduced. After emergency avoidance, automatic return to the original position cannot be achieved, and the degree of automation is low. While protecting the charging piles, it cannot protect the workshop, and the vehicle wheel pressure problem caused by the charging gun cable dragging on the ground is not solved. The collision protection level of the charging pile equipment is not high. Summary of the invention

When the vehicle enters charging mode, the system box is rotated toward the direction of the vehicle, and the charging gun is pulled. The wire is wound in the rocker arm connecting rod and the system box, and has an automatic retractable function. S2. For anti-collision protection, when the monitoring camera identifies that a vehicle enters the warning range, the alarm will sound a loud alarm reminder through the alarm. When the vehicle enters the avoidance limit range, feedback is sent to the charging pile to implement anti-collision protection measures; S3. Under normal circumstances, the energy storage spring overcomes its own elastic deformation, stores elastic potential energy, and responds quickly after receiving an emergency collision warning signal. The potential energy of the energy storage spring is converted into kinetic energy, driving the swing arm seat and the articulated arm to rotate axially along the rotating core shaft to the collision mode. When a collision occurs, the first buffer articulated shaft and the second buffer articulated shaft are both provided with articulated springs to overcome elastic deformation and absorb impact kinetic energy. S4. When the central axis moves inward rapidly under the action of external force, the main plug compresses the air in the air storage chamber, pushing the blocking plunger to move linearly along the inside of the cylinder body, thereby pushing the liquid in the liquid storage chamber into the liquid inlet chamber through the liquid discharge hole, achieving buffering and kinetic energy damping at the same time; when an emergency collision warning signal is received, the potential energy of the energy storage spring is converted into kinetic energy, driving the swing arm seat and the articulated large arm to rotate axially along the rotating core shaft, thereby driving the ball head connector in the hydraulic damping mechanism to enter the limit slide groove through the buffer roller shaft along the guide slide groove to achieve damping; S5, the cylinder pushes the push rod core shaft through the cylinder push rod, thereby pushing the spring buckle to move forward, loosening the locking nail, and the conical boss is separated from the conical sleeve. Under the action of the support spring, the charging pile distribution box swings on the main support plate, and when hit by an external force, it swings in the direction of impact; S6, the spring buckle moves forward, the guide slide moves along the guide slide groove, the claw guide inclined surface moves along the locking boss, the claw expands along the radial direction of the spring buckle, the conical sliding surface leaves the claw engagement surface, and the conical boss is separated from the conical sleeve. Conversely, when closed, the locking nail is fixed by engaging the conical sliding surface, the spring buckle moves backward, and the claw contracts along the radial direction of the spring buckle; S7. When the charging pile distribution box needs to be fixed, the hydraulic power winding machine pulls the traction wire rope to pull the locking nail into the spring buckle. After locking, the hydraulic power winding machine enters a powerless state. When an emergency collision warning signal is received, the traction wire rope quickly responds, and the traction wire rope moves in the opposite direction under the elastic force of the support spring. S8. When a collision occurs, after multi-level buffering, when slight friction occurs, the elasticity of the outer sheet metal elastic pad itself is used to slide and bounce to avoid scratches; Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up a conical locking escape mechanism, the charging pile can respond quickly after receiving an emergency collision warning signal, disengage the conical lock, and the charging pile can swing under the action of the spring to reduce the hard contact caused by the collision, reduce the deformation and damage of the charging pile caused by the collision, and reduce the irreversible damage to the components inside the distribution cabinet caused by hard contact collision, effectively reducing the degree of damage to the components during the collision.

[0015] 2. By setting up a traction return mechanism, the cone lock can be automatically returned to its position by traction after emergency avoidance, without the need for manual handling and installation, which improves the automation level of the equipment and reduces the labor intensity.

[0016] 3. By setting up a retractable buffer protection mechanism, it responds quickly after receiving the emergency collision warning signal, and the buffer roller automatically extends to block between the vehicle and the charging pile. The flexible material used in the buffer roller not only protects the charging pile, but also plays a protective role for the workshop, avoiding damage to the vehicle caused by hard contact.

[0017] 4. By setting up a hydraulic damping mechanism, the impact force generated by the vehicle collision buffer roller can be effectively absorbed, effectively reducing the deformation of the telescopic buffer protection mechanism during the collision process and improving the anti-collision performance.

[0018] 5. By setting up a rocker arm charging gun mechanism, the vehicle wheel pressure problem caused by the charging gun cable dragging on the ground is effectively solved, and the problem of charging at other locations of the charging pile under extreme conditions is also solved.

[0019] 6. By setting up a system identification alarm mechanism, when a vehicle enters the warning range, a loud alarm will be sounded through the alarm. When it enters the avoidance limit range, feedback will be given to the charging pile to implement anti-collision protection measures, effectively improving the intelligence and digitization of the charging pile.

[0020] 7. By setting the outer sheet metal elastic pad, the outer surface damage of the charging pile outer sheet metal during the collision is effectively protected, and the collision protection level of the equipment is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] A method for using an anti-collision intelligent new energy vehicle outdoor charging pile comprises the following steps: S1.

When the vehicle enters the avoidance limit range, feedback is sent to the charging pile to implement anti-collision protection measures. S3. Under normal circumstances, the energy storage spring 405 overcomes its own elastic deformation, stores elastic potential energy, and responds quickly after receiving the emergency collision warning signal. The potential energy of the energy storage spring 405 is converted into kinetic energy, driving the swing arm seat 402 and the articulated arm 406 to rotate axially along the rotating core shaft 404 to the collision mode.

When the central axis 504 moves inward rapidly under the action of external force, the main plug 505 compresses the air in the air storage chamber 513, pushing the blocking plunger 509 to move linearly along the inside of the cylinder body 501, thereby pushing the liquid in the liquid storage chamber 514 into the liquid inlet chamber 515 through the liquid discharge hole 516, achieving buffering and kinetic energy damping at the same time; when receiving the emergency collision warning signal, the potential energy of the energy storage spring 405 is converted into kinetic energy, driving the swing arm seat 402 and the articulated arm 406 to rotate axially along the rotating core shaft 404, thereby driving the ball head connector 511 in the hydraulic damping mechanism 5 to enter the limiting slide groove 414 along the guide slide groove 413 through the buffer roller shaft 412, achieving damping; S5, the cylinder 220 pushes the push rod core shaft 217 through the cylinder push rod 219, thereby pushing the spring buckle 208 to move forward, loosening the locking nail 206, and the conical boss 205 is separated from the conical shaft sleeve 213. Under the action of the support spring 204, the charging pile distribution box 1 swings on the main support plate 202, and when hit by an external force, it swings in the direction of impact; S6, the spring buckle 208 moves forward, the guide slide 212 moves along the guide slide groove 216, the claw guide inclined surface 210 moves along the locking boss 215, the claw 209 expands along the radial direction of the spring buckle 208, the conical sliding surface 207 leaves the claw buckling surface 211, and the conical boss 205 is separated from the conical sleeve 213. On the contrary, when closed, the locking nail 206 is fixed by buckling the conical sliding surface 207, the spring buckle 208 moves backward, and the claw 209 shrinks along the radial direction of the spring buckle 208; S7. When the charging pile distribution box 1 needs to be fixed, the hydraulic power winding machine 304 pulls the traction wire rope 301 to pull the locking nail 206 into the spring buckle 208. After locking, the hydraulic power winding machine 304 enters a powerless state. When an emergency collision warning signal is received, the traction wire rope 301 reacts quickly and moves in the opposite direction under the elastic force of the support spring 204. S8, when a collision occurs, after multi-level buffering, when slight friction occurs, the elasticity of the outer sheet metal elastic pad 8 itself is used to slide and bounce to avoid scratches; Obviously, the above embodiments are merely examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention.
