[0023] The present invention also discloses a method for using a DC charging pile for a new energy vehicle with a protective function, comprising the following steps:

[0024] S1. When the outside of the charging pile is impacted, the impact force will first act on the outer protective plate. At this time, the buffer spring collapses and absorbs energy to alleviate the impact force. The outer protective plate can play a primary protection role for the charging pile;

[0025] S2. After the charging pile shell is impacted, the vibration sensor inside it senses strong vibration. At this time, the control chip inside the charging pile can control the rapid inflation pump to start, and the protective airbag is quickly impacted to expand the protective airbag quickly, and the impact force is buffered twice. The above process will be completed quickly at the first time of the collision, and the charging pile will have a timely protection effect;

[0026] S3. When a strong collision occurs in the charging pile and a fire occurs, the temperature inside the device rises suddenly, and the volume of the thermal control block expands due to the heat, thereby driving the locking rod to move sideways, and one end of the locking rod will be separated from the locking holes on one side of the first mounting cover and the second mounting cover;

[0027] S4. At this time, the first mounting cover and the second mounting cover can be deflected downward by the rotating shaft, and the two are close to each other. When the puncture needle of the first mounting cover contacts the high-pressure airbag of the second mounting cover, the puncture needle will pierce the high-pressure airbag. At this time, the high-pressure carbon dioxide gas in the high-pressure airbag will carry the fire extinguishing powder and quickly flow out and distribute to various positions in the charging pile, so as to quickly extinguish the fire point.

[0028] S5, after the first mounting cover and the second mounting cover are deflected, both are in a vertical state, at this time, the first bottom magnetic block and the second bottom magnetic block of the first mounting cover and the second mounting cover correspond to the adsorption magnetic plate of the movable shielding component and are close to each other;

[0029] S6. At this time, since the magnetic poles of the adsorption magnetic plate are different from those of the first bottom magnetic block and the second bottom magnetic block, the first bottom magnetic block and the second bottom magnetic block can generate a strong attraction for the adsorption magnetic plate, which can attract the sealing baffle to lift. At this time, the sealing baffle moves up until the adsorption magnetic plate fits with the first bottom magnetic block and the second bottom magnetic block. At this time, the sealing baffle can complete the shielding of the heat dissipation slot, which can prevent external air from entering the charging pile again and prevent the fire from igniting again;

[0030] S7. When the charging assembly is not in use, it can be directly inserted into the gun plug through the plug. At this time, the positioning pins on the outside of the holster will be inserted into the corresponding pin holes of the gun plug to complete the positioning of the charging assembly. When taking it out, just pull the charging assembly outward.

[0031] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0032] 1. In the present invention, an external protection component is provided. When the outside of the charging pile is impacted, the impact force will first act on the external protection plate. At this time, the buffer spring collapses and absorbs energy to alleviate the impact force. The external protection plate can play a primary protection effect on the charging pile. After the charging pile shell is impacted, the vibration sensor inside it senses strong vibration. At this time, the control chip inside the charging pile can control the fast inflation pump to start, and the protective airbag is quickly impacted to make the protective airbag expand rapidly, and the impact force is buffered for the second time. The above process will be completed quickly at the first time of the collision, and the charging pile will have a timely protection effect. Through this design, the charging pile can be given a secondary protection effect when it is impacted from the outside, and the main body of the charging pile can be protected to the greatest extent to avoid serious fires and the like. At the same time, the protective airbag will only pop up and work when encountering a large impact force, avoiding leakage or damage caused by long-term internal inflation of the protective airbag, thereby ensuring the actual working effect of the equipment.

[0033] 2. In the present invention, a breakdown component and an inner protection component are also provided in the charging pile. When the charging pile is subjected to a strong collision and a fire occurs, the temperature in the equipment rises suddenly, and the heated volume of the heat control block expands, thereby driving the positioning rod to move sideways. One end of the positioning rod will be separated from the positioning hole on one side of the first mounting cover and the second mounting cover. At this time, the first mounting cover and the second mounting cover can be deflected downward by the rotating shaft, and the two are close to each other. When the breakdown needle of the first mounting cover contacts the high-pressure airbag of the second mounting cover, the breakdown needle will pierce the high-pressure airbag. At this time, the high-pressure carbon dioxide gas in the high-pressure airbag carries the fire extinguishing powder and quickly flows out and is distributed at various positions in the charging pile, so as to quickly extinguish the fire point. Through this design, after the charging pile is subjected to a severe impact and catches fire, the emergency treatment mechanism can be automatically triggered to quickly and effectively extinguish the fire point, thereby effectively preventing the fire from spreading. Combined with the outer protection component, it plays a role in synchronously protecting the inside and outside of the charging pile, which can greatly improve the use effect of the charging pile and eliminate safety hazards.

[0034] 3. In the present invention, a movable shielding component is provided in the device. When the first mounting cover and the second mounting cover are deflected, both are in a vertical state. At this time, the first bottom magnetic block and the second bottom magnetic block of the first mounting cover and the second mounting cover correspond to each other and are close to the adsorption magnetic plate of the movable shielding component. At this time, since the magnetic poles of the adsorption magnetic plate are different from those of the first bottom magnetic block and the second bottom magnetic block, the first bottom magnetic block and the second bottom magnetic block can generate a strong attraction for the adsorption magnetic plate, which can attract the sealing baffle to lift. At this time, the sealing baffle moves up until the adsorption magnetic plate is fitted with the first bottom magnetic block and the second bottom magnetic block. At this time, the sealing baffle can complete the shielding of the heat dissipation groove, and can prevent external air from entering the charging pile again, and prevent the fire from igniting again. Through this design, the movement control of the sealing baffle can be realized after the fire extinguishing mechanism is triggered, thereby preventing external air from entering the equipment, effectively preventing the flame from rekindling, and also preventing the fire from spreading outside, further improving the application safety of the charging pile.

[0035] 4. In the present invention, a charging assembly is provided, and when not in use, the charging assembly can be directly inserted into the gun inserter through a plug. At this time, the positioning pins on the outside of the holster will be inserted into the corresponding pin holes of the gun inserter to complete the positioning of the charging assembly. When taking it out, the charging assembly can be directly pulled outward, which is convenient and quick to use, saving time and effort. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] See also Figure 1-Figure 11The present invention provides a technical solution: a DC charging pile for new energy vehicles with a protective function, comprising a charging pile shell 5, a top shell 1 is fixedly installed on the top of the charging pile shell 5, a base 3 is fixedly installed on the bottom of the charging pile shell 5, a touch screen 12 and an outer protective component 4 are arranged on the outer wall of one side of the charging pile shell 5, the outer protective component 4 is located on the outer side of the touch screen 12, a heat dissipation groove 8 is arranged on the outer wall of the rear side of the charging pile shell 5, a heat dissipation fin 6 is rotatably installed inside the heat dissipation groove 8 through a rotating shaft, and an inspection door 7 is installed on the outer wall of the other side of the charging pile shell 5 through a hinge;

[0051] A rotating hole is provided on the inner surface of the charging pile shell 5, and a breakdown component 9 and an inner protection component 10 are rotatably installed in the rotating hole. The inner protection component 10 is used for protection inside the charging pile shell 5, the breakdown component 9 is used for automatic triggering of the inner protection component 10, and the outer protection component 4 is used for external impact protection of the charging pile.

[0052] The outer protection component 4 includes an outer protection plate 42 and a quick air pump 45. The quick air pump 45 is fixedly installed on the inner wall of the bottom surface of the charging pile shell 5. An air filling tube 44 is fixedly installed on the outside of the quick air pump 45. A plurality of buffer springs 41 are fixedly installed on the outer wall of one side of the outer protection plate 42. One end of the plurality of buffer springs 41 is fixedly connected to the outer wall of one side of the charging pile shell 5. A protective airbag 43 is arranged on one side of the buffer spring 41 and located on the outer wall of one side of the outer protection plate 42. One end of the air filling tube 44 is fixedly connected to the air hole arranged on the outer surface of the protective airbag 43. A vibration sensor is arranged inside the charging pile shell 5.

[0053] The specific implementation method is as follows: when the outside of the charging pile is impacted, the impact force will first act on the outer protective plate 42. At this time, the buffer spring 41 collapses and absorbs energy to alleviate the impact force. The outer protective plate 42 can play a primary protection effect on the charging pile. After the charging pile shell 5 is impacted, the vibration sensor inside it senses the strong vibration. At this time, the control chip inside the charging pile can control the fast inflation pump 45 to start, and quickly impact the protective airbag 43, so that the protective airbag 43 expands quickly, and performs secondary buffering on the impact force. The above process will be completed quickly at the first time of the collision, which will produce timely protection effect for the charging pile.

[0054] Through this design, the charging pile can be given a secondary protection effect when it is subjected to external impact, thereby protecting the main body of the charging pile to the greatest extent and avoiding serious fires and the like. At the same time, the protective airbag 43 will only pop up and work when encountering a large impact force, thereby avoiding leakage or damage caused by long-term internal inflation of the protective airbag, thereby ensuring the actual working effect of the equipment.

[0055] The breakdown component 9 includes a first mounting cover 91, which is rotatably mounted inside the charging pile shell 5 through a rotating shaft. A bottom groove is provided at the bottom of the first mounting cover 91, and a plurality of breakdown pins 93 are fixedly mounted in the bottom groove. A first bottom magnetic block 92 is fixedly mounted at one end of the first mounting cover 91.

[0056] The inner protection component 10 includes a second mounting cover 101, which is rotatably mounted inside the charging pile shell 5 through a rotating shaft. A bottom groove is provided at the bottom of the second mounting cover 101, and a high-pressure airbag 104 is provided in the bottom groove. A feeding nozzle 103 is provided on the bottom surface of the high-pressure airbag 104. The interior of the high-pressure airbag 104 is filled with high-pressure carbon dioxide gas and fire extinguishing powder, and a second bottom magnetic block 102 is fixedly installed at one end of the high-pressure airbag 104.

[0057] An inner installation groove 15 is provided on the inner wall of the charging pile shell 5, and an inner slide rail 17 is fixedly installed on the inner wall of the inner installation groove 15. A thermal control component 16 is provided inside the inner installation groove 15, and the thermal control component 16 is used to position the breakdown component 9 and the inner protection component 10. The thermal control component 16 includes a thermal control block 162, and the thermal control block 162 is slidably installed on the inner slide rail 17 through a side slide groove 163 provided on the outside thereof. A locking rod 161 is fixedly installed on one side outer wall of the thermal control block 162, and a locking hole is provided on one side outer wall of the first mounting cover 91 and the second mounting cover 101, and one end of the locking rod 161 is locked into the locking hole.

[0058] The specific implementation method is as follows: when the charging pile collides violently and a fire occurs, the temperature inside the equipment suddenly rises, and the volume of the thermal control block 162 expands due to the heat, thereby driving the locking rod 161 to move sideways. One end of the locking rod 161 will disengage from the locking holes on one side of the first mounting cover 91 and the second mounting cover 101. At this time, the first mounting cover 91 and the second mounting cover 101 can be deflected downward by the rotating shaft, and the two are close to each other. When the penetration needle 93 of the first mounting cover 91 contacts the high-pressure airbag 104 of the second mounting cover 101, the penetration needle 93 will pierce the high-pressure airbag 104. At this time, the high-pressure carbon dioxide gas in the high-pressure airbag 104 carrying the fire extinguishing powder will quickly gush out and be distributed in various positions in the charging pile, so as to quickly extinguish the fire point.

[0059] Through this design, after the charging pile is hit violently and catches fire, the emergency response mechanism can be automatically triggered to quickly and effectively extinguish the fire point, thereby effectively preventing the fire from spreading. Combined with the external protection component 4, it plays a role in synchronously protecting the charging pile inside and outside, which can greatly improve the use effect of the charging pile and eliminate safety hazards.

[0060] A built-in guide rail 14 is fixedly installed on the inner wall of one side of the charging pile shell 5, and a movable shielding component 13 is slidably installed on the outside of the built-in guide rail 14. The movable shielding component 13 is used for sealing and shielding inside the charging pile shell 5. The movable shielding component 13 includes a sealing baffle 133, and the sealing baffle 133 is slidably installed on the built-in guide rail 14 through a movable groove 134 set on the outer wall of one side thereof. An adsorption magnetic plate 131 is fixedly installed on the outer wall of one side of the sealing baffle 133, and the magnetic poles of the adsorption magnetic plates 131 are different from those of the first bottom magnetic block 92 and the second bottom magnetic block 102. Side rollers 132 are rotatably installed on the outer walls of both sides of the sealing baffle 133 through a rotating shaft, and the side rollers 132 are rollingly connected to the inner wall of one side of the charging pile shell 5.

[0061] The specific implementation method is as follows: after the first mounting cover 91 and the second mounting cover 101 are deflected, both are in a vertical state. At this time, the first bottom magnetic block 92 and the second bottom magnetic block 102 of the first mounting cover 91 and the second mounting cover 101 correspond to each other and are close to the adsorption magnetic plate 131 of the movable shielding component 13. At this time, since the magnetic poles of the adsorption magnetic plate 131 are different from those of the first bottom magnetic block 92 and the second bottom magnetic block 102, the first bottom magnetic block 92 and the second bottom magnetic block 102 can generate a strong attraction for the adsorption magnetic plate 131, which can attract the sealing baffle 133 to lift. At this time, the sealing baffle 133 moves up until the adsorption magnetic plate 131 is in contact with the first bottom magnetic block 92 and the second bottom magnetic block 102. At this time, the sealing baffle 133 can complete the shielding of the heat dissipation slot 8, thereby preventing external air from entering the charging pile again and preventing the fire from igniting again.

[0062] Through this design, after the fire extinguishing mechanism is triggered, the movement of the sealing baffle 133 can be controlled, thereby preventing external air from entering the equipment, effectively avoiding the flame from reigniting, and preventing the fire from spreading outside, further improving the safety of charging pile applications.

[0063] A gun plugger 11 is fixedly mounted on one side outer wall of the charging pile shell 5, and a charging assembly 2 is provided at one end of the gun plugger 11. The charging assembly 2 is used for stable charging of the vehicle. The charging assembly 2 includes a gun handle 25, and a holster 21 is fixedly mounted on one end of the gun handle 25. A plug 23 is fixedly mounted on one end of the holster 21. A plurality of positioning pins 22 are provided on the outer surface of the holster 21. The positioning pins 22 are embedded in pin holes provided on the side wall of the gun plugger 11. The other end of the gun handle 25 is fixedly connected to the side wall of the base 3 through an electric wire 24.

[0064] The specific implementation method is as follows: when the charging component 2 is not in use, it can be directly inserted into the gun inserter 11 through the plug 23. At this time, the positioning pins 22 on the outside of the holster 21 will be inserted into the corresponding pin holes of the gun inserter 11 to complete the positioning of the charging component 2. When taking it out, just pull the charging component 2 outward. It is convenient and quick to use, saving time and effort.

[0065] The present invention also discloses a method for using a DC charging pile for a new energy vehicle with a protective function, comprising the following steps:

[0066] S1. When the outside of the charging pile is impacted, the impact force will first act on the outer protective plate 42. At this time, the buffer spring 41 collapses and absorbs energy to alleviate the impact force. The outer protective plate 42 can play a primary protective effect on the charging pile.

[0067] S2. After the charging pile shell 5 is impacted, the vibration sensor inside it senses a strong vibration. At this time, the control chip inside the charging pile can control the fast air pump 45 to start, and the protective airbag 43 is quickly impacted, so that the protective airbag 43 expands quickly, and the impact force is buffered twice. The above process will be completed quickly at the first time of the collision, and the charging pile will have a timely protection effect;

[0068] S3. When a strong collision occurs in the charging pile and a fire occurs, the temperature inside the device rises suddenly, and the volume of the heat control block 162 expands due to the heat, thereby driving the locking rod 161 to move sideways, and one end of the locking rod 161 will be separated from the locking holes on one side of the first mounting cover 91 and the second mounting cover 101;

[0069] S4. At this time, the first mounting cover 91 and the second mounting cover 101 can be deflected downward by the rotating shaft, and the two are close to each other. When the piercing needle 93 of the first mounting cover 91 contacts the high-pressure airbag 104 of the second mounting cover 101, the piercing needle 93 will pierce the high-pressure airbag 104. At this time, the high-pressure carbon dioxide gas in the high-pressure airbag 104 will carry the fire extinguishing powder and quickly flow out and distribute to various positions in the charging pile, so as to quickly extinguish the fire point.

[0070] S5. After the first mounting cover 91 and the second mounting cover 101 are deflected, both are in a vertical state. At this time, the first bottom magnetic block 92 and the second bottom magnetic block 102 of the first mounting cover 91 and the second mounting cover 101 correspond to the adsorption magnetic plate 131 of the movable shielding component 13 and are close to each other;

[0071] S6. At this time, since the magnetic poles of the adsorption magnetic plate 131 are different from those of the first bottom magnetic block 92 and the second bottom magnetic block 102, the first bottom magnetic block 92 and the second bottom magnetic block 102 can generate a strong attraction for the adsorption magnetic plate 131, which can attract the sealing baffle 133 to rise. At this time, the sealing baffle 133 moves up until the adsorption magnetic plate 131 fits with the first bottom magnetic block 92 and the second bottom magnetic block 102. At this time, the sealing baffle 133 can complete the shielding of the heat dissipation slot 8, which can prevent external air from entering the charging pile again and prevent the fire from igniting again;

[0072] S7. When the charging assembly 2 is not in use, it can be directly inserted into the gun inserter 11 through the plug 23. At this time, the positioning pins 22 on the outside of the holster 21 will be inserted into the corresponding pin holes of the gun inserter 11 to complete the positioning of the charging assembly 2. When taking it out, just pull the charging assembly 2 outward.

[0073] Working principle: When the outside of the charging pile is impacted, the impact force will first act on the outer protective plate 42. At this time, the buffer spring 41 collapses and absorbs energy to alleviate the impact force. The outer protective plate 42 can play a primary protection effect on the charging pile. After the charging pile shell 5 is impacted, the vibration sensor inside it senses strong vibration. At this time, the control chip inside the charging pile can control the fast inflation pump 45 to start, and quickly impact the protective airbag 43, so that the protective airbag 43 expands quickly, and the impact force is buffered for the second time. The above process will be completed quickly at the first time of the collision, and a timely protection effect will be produced for the charging pile;

[0074] When a strong collision occurs in the charging pile and a fire occurs, the temperature inside the device rises suddenly, and the volume of the heat control block 162 expands due to the heat, thereby driving the positioning rod 161 to move sideways, and one end of the positioning rod 161 will be separated from the positioning hole on one side of the first mounting cover 91 and the second mounting cover 101; at this time, the first mounting cover 91 and the second mounting cover 101 can be deflected downward through the rotating shaft, and the two are close to each other. When the penetration needle 93 of the first mounting cover 91 contacts the high-pressure airbag 104 of the second mounting cover 101, the penetration needle 93 will pierce the high-pressure airbag 104. At this time, the high-pressure carbon dioxide gas in the high-pressure airbag 104 will carry the fire extinguishing powder and quickly gush out and distribute to various positions in the charging pile, so as to quickly extinguish the fire point;

[0075] When the first mounting cover 91 and the second mounting cover 101 are deflected, both are in a vertical state. At this time, the first bottom magnetic block 92 and the second bottom magnetic block 102 of the first mounting cover 91 and the second mounting cover 101 correspond to each other and are close to the adsorption magnetic plate 131 of the movable shielding component 13; at this time, since the magnetic poles of the adsorption magnetic plate 131 are different from those of the first bottom magnetic block 92 and the second bottom magnetic block 102, the first bottom magnetic block 92 and the second bottom magnetic block 102 can generate a strong attraction for the adsorption magnetic plate 131, which can attract the sealing baffle 133 to lift. At this time, the sealing baffle 133 moves up until the adsorption magnetic plate 131 fits with the first bottom magnetic block 92 and the second bottom magnetic block 102. At this time, the sealing baffle 133 can complete the shielding of the heat dissipation slot 8, which can prevent external air from entering the charging pile again and prevent the fire from igniting again;

[0076] When the charging assembly 2 is not in use, it can be directly inserted into the gun inserter 11 through the plug 23. At this time, the positioning pins 22 on the outside of the holster 21 will be inserted into the corresponding pin holes of the gun inserter 11 to complete the positioning of the charging assembly 2. When taking it out, just pull the charging assembly 2 outward.

After the charging pile shell (5) is impacted, the vibration sensor inside it senses a strong vibration. At this time, the control chip inside the charging pile can control the rapid inflation pump (45) to start, and the protective airbag (43) is quickly impacted, so that the protective airbag (43) expands rapidly, and the impact force is buffered twice. The above process will be completed quickly at the first time of the collision, and a timely protection effect will be produced for the charging pile; S3. When a strong collision occurs in the charging pile and a fire occurs, the temperature inside the device rises suddenly, and the volume of the heat control block (162) expands due to the heat, thereby driving the locking rod (161) to move sideways, and one end of the locking rod (161) will be separated from the locking holes on one side of the first mounting cover (91) and the second mounting cover (101); S4.
