Description

Technical Field

[0001] This invention relates to the field of outdoor charging pile technology, and in particular to an impact-resistant intelligent outdoor charging pile and method for new energy vehicles. Background Technology

[0002] The emergence of smart charging stations is an inevitable product of the development of new energy vehicle technology. Integrating advanced technologies such as the Internet of Things, big data, and cloud computing, it enables intelligent, automated, and remote management of the charging process. Through intelligent identification, precise control, and multiple protection functions, smart charging stations provide electric vehicle users with an unprecedented charging experience. This technological innovation not only improves charging efficiency and reduces charging costs, but also subtly drives a transformation in travel methods.

[0003] Leveraging big data and cloud computing technologies, smart charging station systems can intelligently recommend the best charging stations and charging times based on information such as the user's travel route, vehicle type, and battery status. This not only saves users time searching for charging stations but also avoids travel delays caused by charging inconvenience.

[0004] With the continuous development and widespread application of smart charging pile technology, future travel will become 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 technology, forming a more complete intelligent travel ecosystem. In this ecosystem, vehicles, roads, charging facilities, and other components will achieve information sharing 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, future travel 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 the energy structure; at the same time, through intelligent management and service methods, they will reduce energy consumption and carbon emissions, contributing to the sustainable development of the planet.

[0006] Although new energy vehicles have been in use for many years, they are still considered a novelty. After charging stations are installed and operational, user information needs to be collected and analyzed, followed by optimization and feedback. Feedback from vehicle manufacturers and battery manufacturers is particularly frequent, mainly focusing on four issues:

[0007] 1) The driving range of new energy electric vehicles is relatively short.

[0008] 2) When using a charging station, it usually takes a long time to fully charge the battery.

[0009] 3) The coverage of charging pile facilities needs to be further expanded. Currently, there is a clear shortage of them, which cannot meet market demand.

[0010] 4) Potential issues related to the installation standards of charging piles have not been properly addressed.

[0011] Safety protocols are paramount when installing charging stations. Due to the inherent risks of charging stations, any installation defects can lead to serious consequences. For example, high voltage can pose a threat to users; poor grounding can result in electric shock; if the charging gun plug is not securely locked or lacks an electronic lock, the plug will remain energized when used, posing a significant danger; improper installation (such as poor sealing or inadequate waterproofing) can lead to short circuits and electric shocks. Therefore, strict protocols must be followed during installation to ensure the safety of both personnel and users. Installation sites may be affected by weather conditions such as rain, necessitating the construction of rain shelters to protect equipment and personnel. All installation and maintenance work should be supervised to enhance the responsibility and technical skills of staff; regular training is also essential to improve installation quality and safety.

[0012] For example, application number 202111200433.8 discloses an anti-collision structure and a charging pile having the structure, which relates to the field of charging piles. It includes: a charging body, a protective part, and a rain shelter. When the charging pile is hit by a vehicle or other factors, the protective plate of the protective device is first impacted to avoid damage to the surface of the charging pile. Then, the first protective spring applies 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 damage after the charging pile falls to the ground.

[0013] However, most current charging piles suffer from hard contact due to collisions, resulting in deformation and damage to the charging piles and irreversible damage to internal components of the distribution cabinet caused by the hard contact collisions. This fails to reduce the degree of damage to components during the collision process. After emergency avoidance, they cannot automatically return to their original positions, resulting in a low level of automation. While protecting the charging piles, they cannot protect the workshop. The problem of vehicle wheel pressure caused by charging gun cables dragging on the ground has not been resolved, and the collision protection level of the charging pile equipment is not high. Summary of the Invention

[0014] The technical problem this invention aims to solve is to reduce hard contact caused by collisions with charging piles, thereby reducing deformation and damage to the charging piles and irreversible damage to internal components of the distribution cabinet caused by hard contact collisions. This reduces the degree of damage to components during the collision process. After emergency avoidance, the device automatically returns to its original position, improving the automation level of the equipment. While protecting the charging piles, it also protects the workshop, solves the problem of vehicle wheel pressure caused by charging gun cables dragging on the ground, and improves the collision protection level of the charging pile equipment.

[0025] Preferably, the impact-resistant intelligent outdoor charging pile for new energy vehicles further includes an outer sheet metal elastic pad; the outer sheet metal elastic pad is fixedly installed on the lower outer surface of the front protective door, rear protective door, and side protective door;

[0026] A method for using an impact-resistant intelligent outdoor charging station for new energy vehicles includes the following steps:

[0027] S1. When the vehicle enters the charging phase, rotate the system box towards the vehicle and pull the charging gun. The power cord is coiled inside the rocker arm connecting rod and the system box, with an automatic extension and retraction function.

[0028] S2. Regarding collision avoidance protection, when the monitoring camera identifies a vehicle entering the warning range, it will issue a loud alarm through the alarm device. When the vehicle enters the avoidance limit range, it will send a feedback to the charging pile to implement collision avoidance protection measures.

[0029] S3. Under normal circumstances, the energy storage spring overcomes its own elastic deformation and stores elastic potential energy. After receiving an emergency collision warning signal, it reacts quickly and converts the potential energy of the energy storage spring into kinetic energy, which drives the swing arm seat and the hinged arm to rotate along the axis of the rotating spindle to the collision mode. When a collision occurs, hinge springs are provided on the first buffer hinge shaft and the second buffer hinge shaft to overcome elastic deformation and absorb the impact kinetic energy.

[0030] S4. When the central shaft moves rapidly inward under 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, thereby pushing the liquid in the liquid storage chamber into the liquid inlet chamber through the drain hole, achieving buffering while performing kinetic energy damping; 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 hinged large arm to rotate axially along the rotating spindle, thereby driving the ball joint connector in the hydraulic damping mechanism to enter the limiting slide groove through the buffer roller shaft along the guide slide groove, achieving the damping effect;

[0031] S5. The cylinder pushes the push rod spindle through the cylinder push rod, thereby pushing the spring buckle forward, releasing the locking pin, the conical boss disengages from the conical bushing, and under the action of the support spring, the charging pile distribution box swings on the main support plate, and when it is hit by an external force, it swings in the direction of impact.

[0032] S6. The spring buckle moves forward, the guide slide moves along the guide groove, the pawl guide ramp moves along the locking boss, the pawl expands in the radial direction of the spring buckle, the conical slide surface leaves the pawl engagement surface, and the conical boss disengages from the conical bushing. Conversely, when closed, the locking pin is fixed by engaging the conical slide surface, the spring buckle moves backward, and the pawl retracts in the radial direction of the spring buckle.

[0033] S7. When it is necessary to fix the charging pile distribution box, the hydraulic power winding machine pulls the traction steel wire rope to pull the locking pin into the spring buckle. After locking, the hydraulic power winding machine enters a non-powered state. When it receives an emergency collision warning signal, it reacts quickly and the traction steel wire rope moves in the opposite direction under the elastic force of the support spring.

[0034] S8. In the event of a collision, after multi-level buffering, when slight friction occurs, the outer sheet metal elastic pad itself will slide and bounce to avoid scratching.

[0035] Compared with the prior art, the beneficial effects of the present invention are:

[0036] 1. By setting up a conical locking escape mechanism, the charging pile can react quickly after receiving an emergency collision warning signal, disengage from the conical lock, and swing under the action of the spring to reduce the hard contact caused by the collision, thereby reducing the deformation and damage of the charging pile caused by the collision and the irreversible damage to the internal components of the power distribution cabinet caused by the hard contact collision, effectively reducing the degree of damage to the components during the collision process.

[0037] 2. By setting up a traction return mechanism, the cone lock can be automatically returned to its original position after an emergency avoidance, eliminating the need for manual handling and installation, thus improving the automation level of the equipment and reducing the intensity of manual labor.

[0038] 3. By setting up a telescopic buffer protection mechanism, it reacts quickly after receiving an emergency collision warning signal. The buffer roller automatically extends to block between the vehicle and the charging pile. The flexible material used in the buffer roller protects the charging pile while also protecting the vehicle, avoiding damage to the vehicle from hard contact.

[0039] 4. By setting up a hydraulic damping mechanism, the impact force generated by the vehicle collision buffer roller can be effectively absorbed, which effectively reduces the deformation of the telescopic buffer protection mechanism during the impact process and improves the anti-collision performance.

[0040] 5. By setting up a rocker arm charging gun mechanism, the problem of vehicle wheel pressure caused by the charging gun cable dragging on the ground is effectively solved, and the problem of charging in other locations of the charging pile under extreme conditions is also solved.

[0041] 6. By setting up a system to identify alarm mechanisms, when a vehicle enters the warning range, the alarm will sound loudly to remind the user. When the vehicle enters the avoidance limit range, the system will send a signal to the charging pile to implement anti-collision protection measures, which effectively improves the intelligence and digitalization of the charging pile.

[0042] 7. By setting up elastic protective pads on the outer sheet metal, the outer surface of the charging pile is effectively protected from damage during collisions, thus improving the equipment's collision protection level. Attached Figure Description

[0057] Example

[0058] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0059] Please see Figures 1-12An impact-resistant intelligent outdoor charging pile for new energy vehicles includes a charging pile distribution box 1. The distribution box 1 comprises a welding frame 101, a front protective door 102, a rear protective door 103, side protective doors 104, a top cover 105, a distribution panel 106, a tempered glass display screen 107, a heat dissipation window 108, and a base plate 109. The front protective door 102 and rear protective door 103 are fixedly arranged facing each other on both sides of the welding frame 101. Two sets of side protective doors 104 are fixedly arranged facing each other. The two sides of the electrical box welding frame 101 are perpendicular to the front protective door 102. The top cover plate 105 is fixedly installed on the top of the electrical box welding frame 101. The bottom plate 109 is fixedly installed on the bottom of the electrical box welding frame 101 and is arranged facing the top cover plate 105.

The two sets of side protective doors 104 are symmetrically provided with multiple sets of heat dissipation windows 108.

[0060] The bottom of the charging pile distribution box 1 is fixedly equipped with a cone-shaped locking escape mechanism 2 for emergency collision avoidance;

[0061] The bottom of the conical locking escape mechanism 2 is fixedly equipped with a traction return mechanism 3 that returns to the normal position;

[0062] In some embodiments, see Figure 4-7The conical locking escape mechanism 2 includes a main support frame 201, a main support plate 202, a transition support plate 203, a support spring 204, a conical boss 205, a locking pin 206, a spring buckle 208, a conical bushing 213, a transition plate 214, a push rod spindle 217, a disc spring 218, a cylinder push rod 219, a cylinder 220, and a spindle hole 221. The transition support plate 203 is fixedly mounted on the main support frame 201, and the main support plate 202 is uniformly fixedly mounted on the transition support plate 203. Multiple sets of the support springs 204 are fixedly connected to the transition support plate 203; the conical boss 205 is fixedly disposed at the center of the bottom of the main support plate 202; the locking pin 206 is fixedly disposed at the end of the conical boss 205 away from the main support plate 202; the transition plate 214 is fixedly disposed at the bottom of the transition support plate 203, and the conical bushing 213 is fixedly disposed on the transition plate 214 and extends towards the transition support plate 203; the inner conical surface of the conical bushing 213 is connected to the transition support plate 203. The outer tapered surface of the tapered boss 205 is matched; the spring buckle 208 is movably disposed within the tapered bushing 213; the push rod spindle 217 is movably disposed within the tapered bushing 213, with one end fixedly disposed at the end of the spring buckle 208 away from the tapered boss 205; multiple sets of disc springs 218 are provided and movably sleeved on the push rod spindle 217; the cylinder push rod 219 is fixedly disposed at the end of the push rod spindle 217 away from the tapered boss 205; and the cylinder 220 is fixedly disposed within the tapered boss 205. The tapered bushing 213 is located away from the tapered boss 205 at one end, and the push rod spindle 217 has a spindle hole 221 at its center. In use, the cylinder 220 pushes the push rod spindle 217 through the cylinder push rod 219, thereby pushing the spring buckle 208 forward, releasing the locking pin 206, and the tapered boss 205 disengages from the tapered bushing 213. Under the action of the support spring 204, the charging pile distribution box 1 swings on the main support plate 202, and swings in the direction of impact when subjected to external force.

[0063] In some embodiments, see Figure 7The locking pin 206 has a tapered sliding surface 207 at the end away from the tapered boss 205. The spring buckle 208 is composed of multiple sets of claws 209, and the end of each claw 209 has a claw engaging surface 211 so that the locking pin 206 is fixed by engaging the tapered sliding surface 207 when closed. The inner side of the tapered bushing 213 has a guide groove 216, the outer circumference of the spring buckle 208 has a guide slide 212, the inner side of the tapered bushing 213 has a locking boss 215, and the spring buckle 208 has a claw guide slope 210 so that when the spring buckle 208 is pushed, the guide slide 212 moves along the guide groove 216, and the claw guide slope 210 moves along the locking boss 215. In use, the spring buckle 208 moves forward, and the guide slide 212 moves along the guide groove 216. When the charging pile is closed, the guide slope 210 of the claw moves along the locking boss 215, the claw 209 expands in the radial direction of the spring buckle 208, the conical sliding surface 207 moves away from the claw engaging surface 211, and the conical boss 205 disengages from the conical bushing 213. Conversely, when closed, the locking pin 206 is fixed by engaging the conical sliding surface 207, the spring buckle 208 moves backward, and the claw 209 retracts in the radial direction of the spring buckle 208. By setting a conical locking escape mechanism, the charging pile can react quickly after receiving an emergency collision warning signal, disengage from the conical lock, and the charging pile swings 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 internal components of the distribution cabinet caused by the hard contact collision, effectively reducing the degree of damage to the components during the collision process.

[0064] In some embodiments, see Figure 5The traction return mechanism 3 includes a traction wire rope 301, a steering seat 302, a guide wheel 303, and a hydraulic winding machine 304. One end of the traction wire rope 301 is fixedly mounted on the locking pin 206, and the other end passes through the spindle hole 221, passes through the guide wheel 303, and is then fixedly mounted on the hydraulic winding machine 304. The steering seat 302 is fixedly mounted on the main support frame 201, and the guide wheel 303 is movably mounted on the steering seat 302 via a spindle. The hydraulic winding machine 304 is fixedly mounted on the main support frame 201. In use, when... When the charging pile distribution box 1 needs to be fixed, the hydraulic power winding machine 304 pulls the traction steel wire rope 301, thereby pulling the locking pin 206 into the spring buckle 208 to achieve locking. After locking, the hydraulic power winding machine 304 enters a non-powered state. When it receives an emergency collision warning signal, it reacts quickly, and the traction steel wire rope 301 moves in the opposite direction under the elastic force of the support spring 204. By setting a traction return mechanism, after emergency avoidance, the cone lock can be automatically returned to its original position by traction, without the need for manual handling and installation, which improves the automation level of the equipment and reduces the intensity of manual labor.

[0065] In some embodiments, see Figure 8-9The impact-resistant intelligent outdoor charging pile for new energy vehicles also includes a telescopic buffer protection mechanism 4. The telescopic buffer protection mechanism 4 includes a rotating fixed bracket 401, a swing arm seat 402, a rotating hinge seat 403, a rotating spindle 404, an energy storage spring 405, a hinged upper arm 406, a first buffer hinge shaft 407, a second buffer hinge shaft 408, a hinge spring 409, a buffer block 410, a buffer roller 411, a buffer roller shaft 412, a guide groove 413, a limiting groove 414, a limiting slider 415, and a stop rod 416.

The rotating hinge seat 403 is fixedly mounted on the fixed bracket 401. It is movably hinged to the swing arm seat 402 via the rotating spindle 404. The energy storage spring 405 is movably sleeved on the rotating spindle 404, with one end fixedly mounted on the rotating fixed bracket 401 and the other end fixedly mounted on the rotating hinge seat 403. One end of the hinge arm 406 is hinged to the rotating hinge seat 403 via the first buffer hinge shaft 407, and the other end is hinged to the buffer block 410 via the second buffer hinge shaft 408. Hinges 409 are sleeved on both the first buffer hinge shaft 407 and the second buffer hinge shaft 408. The buffer roller 411 is movably mounted on the buffer block 410 and in close contact; buffer roller shafts 412 are fixedly mounted at both ends; guide grooves 413 are respectively opened on both sides of the main support frame 201 near the bottom, and a limit slider 415 is opened at the end of the guide groove 413 near the rotating fixed bracket 401. The limit slider 415 is movably mounted in the guide groove 413 to slide along the groove. A stop rod 416 is fixedly mounted at the end of the guide groove 413 away from the rotating fixed bracket 401; in use, under normal conditions, the energy storage spring 405 overcomes its own elastic deformation and stores elastic potential energy. Upon receiving an emergency collision warning signal, the system reacts quickly by converting the potential energy of the energy storage spring 405 into kinetic energy. This kinetic energy drives the swing arm seat 402 and the articulated arm 406 to rotate axially along the rotating spindle 404 to a collision mode. A collision occurs, and articulated springs 409, fitted on both the first and second buffer articulated shafts 407 and 408, overcome elastic deformation and absorb the impact kinetic energy. By incorporating a telescopic buffer protection mechanism, the system reacts quickly upon receiving an emergency collision warning signal, automatically extending the buffer roller to block the vehicle from the charging pile. The flexible material used in the buffer roller protects both the charging pile and the vehicle, preventing damage from hard contact.

[0066] In some embodiments, see Figure 10-12The impact-resistant intelligent outdoor charging pile for new energy vehicles also includes a hydraulic damping mechanism 5. The hydraulic damping mechanism 5 includes a cylinder body 501, a front end cover 502, a double-piece butterfly seal gasket 503, a central shaft 504, a main plug 505, a buffer pad 506, a locking cap 507, a rear end cover 508, a barrier plunger 509, a connecting tailstock 510, a ball joint connector 511, a sleeve connector 512, an air storage chamber 513, a liquid storage chamber 514, a liquid inlet chamber 515, and a drain hole 516. The front end cover 502 and the rear end cover 508 are fixedly installed at both ends of the cylinder body 501. A double-piece butterfly seal gasket 503 is fitted along the inner wall of the cylinder body 501 at the end of the front end cover 502 closest to the cylinder body 501. A central shaft 504 is movably mounted within the cylinder body 501 via a main plug 505. Buffer pads 506 are fixedly mounted at both ends of the main plug 505, and a locking cap 507 is fixedly mounted at the end near the central shaft 504. A barrier plunger 509 is movably mounted within the cylinder body 501, positioned between the main plug 505 and the tail cap 508. A connecting tailstock 510 is fixedly mounted at the end of the tail cap 508 away from the cylinder body 501. A ball joint connector 511 is fixedly mounted at the end of the central shaft 504 away from the main plug 505. A sleeve connector 512 is fixedly mounted at the end of the connecting tailstock 510 away from the tail cap 508. The cylinder body 501... An air storage chamber 513 is formed between the main plug 505 and the barrier plunger 509, and a liquid storage chamber 514 is formed between the main plug 505 and the tail cap 508. A liquid inlet chamber 515 is provided inside the connecting tail seat 510, and a drain hole 516 is provided at the center of the tail cap 508. The ball joint connector 511 is movably connected to the buffer roller shaft 412, and the sleeve connector 512 is movably hinged to the limiting slider 415. In use, when the central shaft 504 moves rapidly inward under external force, the main plug 505 compresses the air in the air storage chamber 513, pushing the barrier plunger 509 to move linearly along the inside of the cylinder 501, thereby pushing the liquid storage chamber... The liquid in 514 enters the inlet chamber 515 through the drain hole 516, achieving buffering while providing kinetic energy damping. When an emergency collision warning signal is received, the potential energy of the energy storage spring 405 is converted into kinetic energy, driving the swing arm seat 402 and the hinged arm 406 to rotate axially along the rotating spindle 404, thereby driving the ball joint connector 511 in the hydraulic damping mechanism 5 to enter the limiting groove 414 through the buffer roller shaft 412 along the guide groove 413, achieving a damping effect. By setting the 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 impact process and improving the anti-collision performance.

[0067] In some embodiments, see Figure 2The impact-resistant intelligent outdoor charging pile for new energy vehicles also includes a rocker arm charging gun mechanism 6. The rocker arm charging gun mechanism 6 includes a rocker arm base 601, a rocker arm connecting rod 602, a system box 603, and a charging gun 604. The rocker arm base 601 has two sets of components that are fixedly mounted on the top cover plate 105 and the system box 603, respectively, and are fixedly connected by the rocker arm connecting rod 602. The charging gun 604 is movably mounted on the system box 603. In use, the system box 603 is rotated towards the vehicle, and the charging gun 604 is pulled. The power cord is coiled inside the rocker arm connecting rod 602 and the system box 603, and has an automatic extension and retraction function. By setting up the rocker arm charging gun mechanism, the problem of vehicle wheel pressure caused by the charging gun cable dragging on the ground is effectively solved, and the problem of charging in other locations of the charging pile under extreme conditions is also solved.

[0068] In some embodiments, see Figure 2 The collision-resistant intelligent outdoor charging pile for new energy vehicles also includes a system identification and alarm mechanism 7, which includes a monitoring camera 701 and an alarm 702. The monitoring camera 701 and the alarm 702 are respectively fixedly installed on the top cover plate 105. In use, when the monitoring camera 701 identifies a vehicle entering the warning range, the alarm 702 will issue a loud alarm reminder. When the vehicle enters the avoidance limit range, the alarm will be fed back to the charging pile for collision protection measures. By setting up the system identification and alarm mechanism, when a vehicle enters the warning range, the alarm will issue a loud alarm reminder. When the vehicle enters the avoidance limit range, the alarm will be fed back to the charging pile for collision protection measures, effectively improving the intelligence and digitalization of the charging pile.

[0069] In some embodiments, see Figure 1 The impact-resistant intelligent outdoor charging pile for new energy vehicles also includes an outer sheet metal elastic pad 8. The outer sheet metal elastic pad 8 is fixedly installed on the lower outer surface of the front protective door 102, rear protective door 103, and side protective door 104. In use, after multi-level buffering in the event of a collision, when slight friction occurs, the outer sheet metal elastic pad 8 can slide and bounce on its own to avoid scratches. By setting the outer sheet metal elastic pad, the outer surface of the charging pile is effectively protected from damage during the collision process, and the collision protection level of the equipment is improved.

[0070] A method for using an impact-resistant intelligent outdoor charging station for new energy vehicles includes the following steps:

[0071] S1. When the vehicle enters the charging phase, rotate the system box 603 towards the vehicle and pull the charging gun 604. The power cord is wound inside the rocker arm connecting rod 602 and the system box 603, with an automatic extension and retraction function.

[0072] S2. Regarding collision protection, when the monitoring camera 701 identifies that a vehicle has entered the warning range, it will issue a loud alarm through the alarm 702. When the vehicle enters the avoidance limit range, it will send a signal to the charging pile to implement collision protection measures.

[0073] S3. Under normal circumstances, the energy storage spring 405 overcomes its own elastic deformation and stores elastic potential energy. After receiving an emergency collision warning signal, it reacts quickly and converts the potential energy of the energy storage spring 405 into kinetic energy, which drives the swing arm seat 402 and the hinged arm 406 to rotate axially along the rotating spindle 404 to the collision mode. When a collision occurs, hinge springs 409 are sleeved on the first buffer hinge shaft 407 and the second buffer hinge shaft 408 to overcome elastic deformation and absorb the impact kinetic energy.

[0074] S4. When the central shaft 504 moves rapidly inward under the action of external force, the main plug 505 compresses the air in the air storage chamber 513, pushes the blocking plunger 509 to move linearly along the inside of the cylinder 501, thereby pushing the liquid in the liquid storage chamber 514 to enter the liquid inlet chamber 515 through the drain hole 516, achieving buffering while performing kinetic energy damping; when an emergency collision warning signal is received, the potential energy of the energy storage spring 405 is converted into kinetic energy, driving the swing arm seat 402 and the hinged large arm 406 to rotate axially along the rotating spindle 404, thereby driving the ball head connector 511 in the hydraulic damping mechanism 5 to enter the limiting slide groove 414 through the buffer roller shaft 412 along the guide slide groove 413, achieving the damping effect;

[0075] S5. The cylinder 220 pushes the push rod spindle 217 through the cylinder push rod 219, thereby pushing the spring buckle 208 to move forward, releasing the locking pin 206, the conical boss 205 disengages from the conical sleeve 213, and under the action of the support spring 204, the charging pile distribution box 1 swings on the main support plate 202, and when it is hit by an external force, it swings in the direction of impact.

[0076] S6. The spring buckle 208 moves forward, the guide slide 212 moves along the guide groove 216, the claw guide inclined surface 210 moves along the locking boss 215, the claw 209 expands in the radial direction of the spring buckle 208, the conical slide surface 207 leaves the claw engagement surface 211, and the conical boss 205 disengages from the conical bushing 213. Conversely, when closed, the locking pin 206 is fixed by engaging the conical slide surface 207, the spring buckle 208 moves backward, and the claw 209 retracts in the radial direction of the spring buckle 208.

[0077] S7. When it is necessary to fix the charging pile distribution box 1, the hydraulic power winding machine 304 pulls the traction steel wire rope 301 to pull the locking pin 206 into the spring buckle 208. After locking, the hydraulic power winding machine 304 enters a non-powered state. When it receives an emergency collision warning signal, it reacts quickly and the traction steel wire rope 301 moves in the opposite direction under the elastic force of the support spring 204.

[0078] S8. When a collision occurs, after multi-level buffering, when slight friction occurs, the outer sheet metal elastic pad 8 will slide and bounce due to its own elasticity to avoid scratching.

[0079] Obviously, the above embodiments are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, these obvious variations or modifications derived from the spirit of the present invention are still within the scope of protection of the present invention.
