Description

Technical Field

[0001] This invention relates to the field of new energy vehicle charging equipment technology, specifically a mobile charging robot for new energy vehicles. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the market has placed higher demands on the flexibility and coverage of charging services. Traditional fixed charging piles suffer from limitations in installation location, large space occupation, and the need for vehicles to actively park, making it difficult to meet the emergency charging needs in scenarios such as parking lots, highway service areas, and residential areas. Mobile charging robots, with their flexible mobility, have become an important solution to this pain point. These devices are typically equipped with multiple battery packs as an energy source and can move autonomously or manually to the target vehicle after receiving a charging order to quickly carry out charging operations. This significantly improves the convenience and adaptability of charging services and is gradually becoming an important development direction in the field of new energy charging.

[0003] However, existing mobile charging robots still have many technical shortcomings in practical applications, especially in terms of heat dissipation and safety protection. During charging, the battery pack continuously generates a large amount of heat. Traditional devices mostly use external fans or heat sinks for passive cooling, which not only consumes additional electrical energy but also has low cooling efficiency, easily leading to excessively high internal temperatures, accelerating battery pack aging and degradation, and even triggering the risk of thermal runaway. At the same time, the safety protection measures of existing devices are relatively simple, mostly relying on fire extinguishers for fire fighting, lacking effective physical barriers. Once the battery pack catches fire, the fire can easily spread rapidly to the entire device, causing serious damage, and it is difficult to prevent the spread of harmful gases produced by combustion, posing a threat to the surrounding environment and personnel safety. Summary of the Invention

[0008] Preferably, a limiting groove is provided in the middle of the inner end of the flame-retardant inner plate, and a T-shaped hook plate is movably installed on the inner end of the flame-retardant outer plate by a tension spring, and the end of the T-shaped hook plate extends into the interior of the limiting groove on the corresponding side.

[0009] Preferably, the inner sidewalls of the limiting groove are equipped with limiting pins via coil springs on both sides, and the inner sidewalls of the flame-retardant outer plate are fixedly equipped with limiting plates near the corresponding side coil springs.

[0010] Preferably, a fixed magnet is fixedly installed at the bottom of the outer side of the flame-retardant outer panel, and an electromagnet is fixedly installed at the position corresponding to each fixed magnet on the inner side wall of the movable chassis.

[0011] Preferably, a high-pressure nitrogen fire extinguishing device is fixedly installed on the inner top of the mobile chassis, and a smoke sensor is fixedly installed on the bottom of the high-pressure nitrogen fire extinguishing device.

[0012] Preferably, a heat dissipation chamber is fixedly installed on one side of the second cylinder, and heat dissipation fins are fixedly installed on the outer diameter of the heat dissipation chamber. The first cylinder is connected to the inner end of the heat dissipation chamber through a connecting pipe.

[0013] Preferably, a drive wheel is fixedly installed on the middle outer diameter of the lower drive shaft, and a driven wheel is fixedly installed on the middle outer diameter of the upper drive shaft. The outer diameters of the drive wheel and the driven wheel are connected by a drive belt.

[0014] Preferably, the mobile chassis is provided with ventilation windows at the top of the front and rear ends.

[0016] Preferably, an inspection door is fixedly installed at the center of the front end of the mobile chassis.

[0017] This invention provides a mobile charging robot for new energy vehicles. It has the following beneficial effects:

[0018] 1. This invention innovatively employs a conversion mechanism from thermal energy to mechanical energy to heat dissipation kinetic energy. During charging, the heat generated by the battery pack is transferred to the first cylinder through a heat-conducting plate and ceramic heat conductor. Utilizing the thermal expansion and contraction characteristics of air, the air displacement device, push rod, cam, and drive shaft are linked, thereby driving the fan blades to rotate and dissipate heat. The entire heat dissipation process requires no external power supply or additional power source, relying entirely on its own residual heat, making it energy-saving and highly efficient. This solves the problem of traditional charging equipment relying on external fans for heat dissipation and high energy consumption.

[0019] 2. When the battery pack catches fire, the smoke sensor of this invention quickly triggers the high-pressure nitrogen fire extinguishing device, which automatically releases nitrogen to reduce the oxygen concentration inside the box and achieve rapid fire extinguishing. At the same time, the electromagnet and the fixed magnet generate a repulsive force, driving the flame-retardant outer plate to fall quickly to block the lower half of the battery pack. Subsequently, through the impact linkage between the T-shaped hook plate and the shock-absorbing base, the flame-retardant inner plate is pushed out, completing the full enclosure and blockage of the upper half of the battery pack. This effectively blocks the spread of fire from both fire extinguishing and fire isolation dimensions, preventing a chain reaction caused by a single battery pack fire, and significantly improving the level of safety protection.

[0028] The technical solutions in 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.

[0029] Example:

[0030] Please see the appendix Figure 1 - Appendix Figure 7 This invention provides a mobile charging robot for new energy vehicles, such as... Figure 1As shown, the device includes a mobile chassis 1, which serves as the mobile carrier for the entire device. It can be moved flexibly and precisely to the location of the new energy vehicle requiring charging, provided as a convenient mobile foundation for charging operations. A housing 2 is fixedly installed on the top of the mobile chassis 1. The housing 2 protects the internal core components such as the battery pack 5 and the shock-absorbing base 3, preventing the intrusion of external dust, rainwater, and other impurities. It also forms a relatively enclosed installation space, ensuring stable operation of all components. A shock-absorbing base 3 is fixedly installed at the bottom of the housing 2. The shock-absorbing base 3 has excellent buffering and shock absorption performance, reducing the impact of vibration on the battery pack 5 during the movement of the mobile chassis 1, preventing damage to the battery pack 5 due to vibration. Several battery slots 4 are evenly distributed on the surface of the shock-absorbing base 3. The battery slots 4 are used to position and install the battery pack 5, ensuring that multiple battery packs 5 are arranged in an orderly manner, improving space utilization, and facilitating concentrated heat conduction. Battery packs 5 are fixedly installed on the surface of each battery slot 4. The battery pack 5 provides a stable power output for the charging operation and is the energy core of the entire charging robot.

[0031] In this embodiment, a heat-conducting plate 6 is fixedly installed at the bottom of the shock-absorbing base 3. The heat-conducting plate 6 can quickly receive the heat generated by the battery pack 5 during operation and efficiently conduct the heat to the ceramic heat conductor 21 below, providing a heat conduction basis for subsequent heat dissipation circulation. The inner bottom of the movable chassis 1 is movably installed with a light rod 7 on both the front and rear sides. The light rod 7 provides movable installation support for the flame-retardant outer plate 8, ensuring that the flame-retardant outer plate 8 can rotate and move smoothly along the light rod 7, realizing the rapid opening and closing blocking function. Several flame-retardant outer plates 8 are movably installed on the outer diameter of the light rod 7. The flame-retardant outer plates 8 can fall quickly when a fire occurs, blocking the lower half of the battery pack 5 and preventing the fire from spreading laterally. The flame-retardant inner plate 9 is movably installed inside the flame-retardant outer plate 8 through the push-out spring 10. The push-out spring 10 can store elastic potential energy and release energy when the triggering condition is met to push the flame-retardant inner plate 9 out, realizing the closed blocking of the upper half of the battery pack 5, forming a fully enclosed fireproof structure.

[0032] Furthermore, a ceramic heat conductor 21 is fixedly installed at the bottom of the shock-absorbing base 3. The ceramic heat conductor 21 has excellent thermal conductivity and can quickly conduct the heat transferred by the heat-conducting plate 6 to the inside of the first cylinder 22, providing a heat source for the thermal expansion and contraction of the air. The first cylinder 22 is fixedly installed inside the ceramic heat conductor 21. The first cylinder 22 provides a sealed space for the gas. After the internal air is heated and expands, it can push the gas transfer device 31 to move, thereby driving the transmission structure to operate. A second cylinder 23 is fixedly installed on the inner bottom of the mobile chassis 1 near the first cylinder 22. The second cylinder 23 and the first cylinder 22 cooperate to form a gas circulation channel. The reciprocating transport of gas is realized by the movement of the rubber piston 35. A lower... The lower drive shaft 27, as the core transmission component, can rotate under gas pressure and transmit power to the upper drive shaft 37. A first cam 28 is fixedly mounted on the outer diameter of the lower drive shaft 27 near the first cylinder 22. The first cam 28 converts the linear motion of the first connecting rod 29 into the rotational motion of the lower drive shaft 27. Simultaneously, during rotation, it pushes the first push rod 30 back to its original position. A first connecting rod 29 is movably mounted at the end of the first cam 28, transmitting the linear driving force of the first push rod 30 to the first cam 28, causing the lower drive shaft 27 to rotate. A first push rod 30 is movably mounted at the end of the first connecting rod 29, and the first push rod 30 moves linearly under the push of the gas shifter 31. The first piston 35 moves, which in turn drives the first cam 28 to rotate via the first connecting rod 29. The end of the first push rod 30 extends into the interior of the first cylinder 22 and is fixedly mounted with an air shifter 31. The air shifter 31 reciprocates under the thermal expansion and contraction of the air inside the first cylinder 22, pushing the gas to circulate between the first cylinder 22 and the heat dissipation chamber 24. The second cam 32 is fixedly mounted on the outer diameter of the lower drive shaft 27 near the second cylinder 23. The second cam 32 cooperates with the second connecting rod 33 to convert the rotational motion of the lower drive shaft 27 into the linear motion of the second push rod 34, realizing the reciprocating movement of the rubber piston 35. The end of the second cam 32 is movably mounted with the second connecting rod 33, which transmits the rotational force of the second cam 32 to the second push rod 34, driving the second piston 35 to move. The movable rubber piston 35 moves within the second cylinder 23. A second push rod 34 is movably mounted at the end of the second connecting rod 33. Driven by the second connecting rod 33, the second push rod 34 pushes the rubber piston 35 to move linearly, adjusting the air pressure within the second cylinder 23. The end of the second push rod 34 extends into the interior of the second cylinder 23 and is fixedly mounted with the rubber piston 35. The rubber piston 35 has good sealing properties and can move under the action of the pressure difference between the external atmospheric pressure and the air pressure inside the second cylinder 23, promoting gas circulation. An upper drive shaft 37 is movably mounted on one side of the inner top of the movable chassis 1. Driven by the drive belt 39, the upper drive shaft 37 rotates, thereby driving the fan blades 40 to rotate and generate airflow. Fan blades 40 are fixedly mounted on both outer diameters of the upper drive shaft 37.When the fan blades 40 rotate, they generate a directional airflow, which quickly dissipates heat from inside the housing 2 through the heat dissipation windows 41, achieving heat dissipation and cooling. Heat dissipation windows 41 are provided at the front and rear ends of the mobile chassis 1, corresponding to each fan blade 40. These windows 41 provide an exhaust channel for hot air inside the housing 2 while also facilitating the entry of cool outside air, creating air convection and improving heat dissipation efficiency.

[0033] Furthermore, a limiting groove 11 is provided in the middle of the inner end of the flame-retardant inner plate 9. The limiting groove 11 is used to accommodate the end of the T-shaped hook plate 12, thereby limiting and fixing the flame-retardant inner plate 9 and preventing it from accidentally popping out when not in operation. The inner end of the flame-retardant outer plate 8 is movably installed with a T-shaped hook plate 12 by a tension spring 13, and the end of the T-shaped hook plate 12 extends into the corresponding limiting groove 11. The T-shaped hook plate 12 is kept in a limiting position on the flame-retardant inner plate 9 under the tension of the tension spring 13. When the flame-retardant outer plate 8 hits the shock-absorbing base 3, the end of the T-shaped hook plate 12 is disengaged from the limiting groove 11 by force, thereby releasing the restriction on the flame-retardant inner plate 9.

[0034] Furthermore, limit pins 14 are movably installed on both sides of the inner wall of the limiting groove 11 via coil springs 15. Under the action of the coil springs 15, the limit pins 14 keep locked to the T-shaped hook plate 12. When the flame-retardant inner plate 9 moves upward, the limit pins 14 rotate accordingly and release the lock. Limit plates 16 are fixedly installed on the inner wall of the flame-retardant outer plate 8 near the corresponding side coil springs 15. The limit plates 16 are used to limit the deformation range of the coil springs 15, prevent the coil springs 15 from losing elasticity due to excessive deformation, and ensure the normal operation of the limit pins 14.

[0035] Furthermore, fixed magnets 17 are fixedly installed at the bottom of the outer side of the flame-retardant outer panel 8. The fixed magnets 17 and electromagnets 18 work together to generate a repulsive force, providing power for the rapid movement of the flame-retardant outer panel 8. Electromagnets 18 are fixedly installed at positions corresponding to each fixed magnet 17 on the inner side wall of the moving chassis 1. When a fire occurs, the electromagnets 18 are energized and generate magnetism, generating a repulsive force with the fixed magnets 17, pushing the flame-retardant outer panel 8 to rotate and fall rapidly along the light rod 7, achieving rapid isolation.

[0036] Furthermore, a high-pressure nitrogen fire extinguishing device 19 is fixedly installed on the inner top of the mobile chassis 1. The high-pressure nitrogen fire extinguishing device 19 automatically releases nitrogen under the trigger of the smoke sensor 20 to reduce the oxygen concentration inside the housing 2 and achieve rapid fire extinguishing. A smoke sensor 20 is fixedly installed at the bottom of the high-pressure nitrogen fire extinguishing device 19. The smoke sensor 20 monitors the smoke concentration inside the housing 2 in real time. When smoke is detected, it immediately triggers the high-pressure nitrogen fire extinguishing device 19 to start and simultaneously controls the electromagnet 18 to be energized, realizing the linkage between fire extinguishing and fire prevention.

[0037] Furthermore, a heat dissipation chamber 24 is fixedly installed on one side of the second cylinder 23, and heat dissipation fins 25 are fixedly installed on the outer diameter of the heat dissipation chamber 24. The heat dissipation chamber 24 provides a heat dissipation space for the gas, and the heat dissipation fins 25 increase the heat dissipation area, which can quickly dissipate the heat in the gas to the outside. The inner end of the first cylinder 22 and the heat dissipation chamber 24 are connected by a connecting pipe 26. The connecting pipe 26 provides a gas flow channel between the first cylinder 22 and the heat dissipation chamber 24, ensuring that the gas can circulate back and forth between the two, so as to realize the continuous transfer and dissipation of heat.

[0038] Furthermore, a drive wheel 36 is fixedly installed on the outer diameter of the middle part of the lower drive shaft 27. The drive wheel 36 rotates with the lower drive shaft 27 and drives the driven wheel 38 to rotate through the transmission belt 39. A driven wheel 38 is fixedly installed on the outer diameter of the middle part of the upper drive shaft 37. The driven wheel 38 rotates under the drive of the transmission belt 39, thereby driving the upper drive shaft 37 to rotate. The outer diameters of the drive wheel 36 and the driven wheel 38 are connected by the transmission belt 39. The transmission belt 39 realizes the power transmission between the drive wheel 36 and the driven wheel 38, and transmits the rotational power of the lower drive shaft 27 to the upper drive shaft 37, driving the fan blade 40 to rotate and dissipate heat.

[0039] Furthermore, ventilation windows 42 are provided at the top of the front and rear ends of the mobile chassis 1. The ventilation windows 42 work together with the heat dissipation windows 41 to further enhance the air circulation inside the housing 2, improve the heat dissipation effect, and at the same time facilitate keeping the air inside the housing 2 dry when not charging, preventing the components from getting damp.

[0040] Furthermore, the output end of the battery pack 5 extends to the outside of the mobile chassis 1 via a wire and is fixedly installed with a charging gun 43. The charging gun 43 is used to insert into the charging port of the new energy vehicle to transfer the electrical energy of the battery pack 5 to the vehicle battery. A gun holder 44 is fixedly installed on one side of the mobile chassis 1 to store the charging gun 43 and prevent the charging gun 43 from being damaged or tangled due to random placement. A control panel 45 is fixedly installed on one side of the mobile chassis 1 near the gun holder 44. The control panel 45 provides an operating interface for the staff and can realize functions such as movement control of the mobile chassis 1, setting charging parameters, and monitoring equipment status, so as to facilitate the staff to quickly carry out charging operations.

[0041] Furthermore, a maintenance door 46 is fixedly installed at the front center of the mobile chassis 1. The maintenance door 46 is designed to be openable and closable, allowing staff to inspect, maintain, and replace the transmission structure, heat dissipation components, battery pack 5, and other internal components of the mobile chassis 1 by opening the maintenance door 46, thereby reducing the difficulty of equipment operation and maintenance and ensuring the long-term stable operation of the equipment.

[0042] Working principle:

[0043] Upon receiving the order, the staff moves the device to the car's charging port by controlling the mobile chassis 1. Then, they remove the charging gun 43 from the gun holder 44 and insert it into the charging port. Charging parameters are set via the control panel 45 to begin charging. During charging, a large amount of heat is generated at the bottom of the battery pack 5. This heat is conducted to the heat-conducting plate 6 and then transferred to the first cylinder 22 via the ceramic heat conductor 21. The air inside the first cylinder 22 expands rapidly due to the heat, pushing the air shifter 31 outward and causing the first push rod 30 to move. The first push rod 30 then moves one end of the first connecting rod 29, causing the other end of the first connecting rod 29 to move as well. The first cam 28 drives the lower drive shaft 27 to rotate. The rotating lower drive shaft 27, in turn, drives the first push rod 30 and the gas shifter 31 inward via the first cam 28, expelling the gas in the first cylinder 22 through the connecting pipe 26 into the heat dissipation chamber 24. The gas in the heat dissipation chamber 24 is rapidly cooled by the cooling fins 25, causing a decrease in air pressure. The external atmospheric pressure then pushes the rubber piston 35 inward, expelling the gas in the heat dissipation chamber 24 in the reverse direction through the connecting pipe 26 back into the first cylinder 22, where it absorbs heat and expands again. This process repeats continuously, driving the lower drive shaft 27 to rotate continuously. The upper drive shaft 37 rotates via the drive wheel 36 and drive belt 39, which in turn drives the fan blades 40 on both sides to rotate, dissipating heat from the housing 2 through the heat dissipation window 41. This process converts the heat generated by the battery pack 5 during operation into mechanical energy, which is then used to drive the fan blades 40 to further dissipate the heat, thus achieving heat dissipation and cooling of the housing 2 during operation. When the battery pack 5 catches fire, the smoke sensor 20 triggers the high-pressure nitrogen fire extinguishing device 19, automatically releasing nitrogen to quickly reduce the oxygen concentration inside the housing for fire extinguishing. Simultaneously, all electromagnets 18 are energized and generate magnetism. The flame-retardant outer plate 8 rotates rapidly due to the repulsive force generated by the fixed magnet 17. The flame-retardant outer plates 8 on both sides fall rapidly, blocking the lower half of each battery pack 5. After the flame-retardant outer plate 8 contacts the shock-absorbing base 3, the end of the T-shaped hook plate 12 hits the shock-absorbing base 3, pushing the flame-retardant inner plate 9 upward. When the flame-retardant inner plate 9 moves upward, it will drive the limiting pin 14 to move along with it. The coil spring 15 is used to rotate the limiting pin 14, so that the T-shaped hook plate 12 releases its limiting effect on the limiting pin 14. Then, the push-out spring 10 releases the elastic potential energy, popping out the flame-retardant inner plate 9, blocking the upper half of each battery pack 5, and preventing the fire from spreading.
