Description

Technical Field

[0001] The present invention relates to a fast charging pile device, and in particular to a fast charging pile device with adaptive voltage regulation. Background Art

[0002] Currently, the charging voltages for different types of new energy electric vehicles vary, mostly 12V or 24V. When charging using a charging station, the appropriate voltage should be selected to avoid the dangers of incorrectly charging at negative or overvoltage levels. Fast charging is achieved by increasing the current, which significantly increases the heat generated by the battery pack. Therefore, good heat dissipation is particularly important for the safety of the battery pack. However, existing charging station devices lack fire protection and heat dissipation functions for new energy electric vehicles during the charging process. When a new energy electric vehicle's battery pack fails due to some reason (such as overheating) and catches fire, the lack of fire protection can easily spread to nearby facilities (primarily other vehicles and charging stations), thereby increasing danger and economic losses, highlighting the shortcomings of existing technologies.

[0014] Compared with the existing technology, the present invention has the following advantages: the present invention monitors the temperature of the vehicle through a thermal imaging sensor. When the vehicle temperature is high, the fan is started to dissipate heat from the bottom of the vehicle. When the current is increased for fast charging, the fan can also be actively controlled to work, thereby improving safety. When it is identified that the vehicle temperature is higher than the safety threshold, the electronic control system controls the electric telescopic mechanism to extend, thereby causing the lifting platform to rise and the flame-retardant cloth to unfold, thereby enclosing the vehicle, reducing the possible tendency of fire spread, reducing damage to surrounding facilities, and realizing fire protection function.

[0015] By utilizing the flame-retardant cloth's water-absorbing and breathable characteristics and the water spray holes on the flame-retardant cloth, the water content of the flame-retardant cloth is increased, the heat dissipation effect is enhanced and the spread of fire is delayed. When the flame-retardant cloth is fully extended, its air permeability will be greatly reduced due to its relatively high water content. At this time, if the electric vehicle burns and produces an open flame, the oxygen entering the surrounding area of the electric vehicle will be reduced, thereby achieving a flame retardant effect and improving the fire protection function.

[0016] When the thermal imaging sensor senses that the battery pack temperature exceeds the safety threshold, the connector can automatically disconnect the plug and socket, thereby blocking the risk of fire spreading along the charging cable to the charging pile, improving fire protection functions and reducing economic losses.

DETAILED DESCRIPTION

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figures 1-10 As shown, a fast charging pile device with adaptive voltage regulation includes a charging pile 1, a camera 2, a charging gun, a transformer component 4, an electronic control system, a parking platform 6, a receiving slot 7, an electric telescopic mechanism, a lifting platform 9, a flame retardant cloth 10, a thermal imaging sensor 11, and a fan 12. The charging pile 1 is equipped with a camera 2 for identifying license plates and a charging gun for charging electric vehicles, and has a built-in transformer component 4 and an electronic control system. A vertical annular receiving slot 7 is opened at the top of the parking platform 6, and an electric telescopic mechanism is installed in the receiving slot 7. The telescopic mechanism is controlled by a lifting platform 9 that moves up and down relative to the accommodating tank 7. The lifting platform 9 can close and block the upper part of the accommodating tank 7. A cylindrical flame-retardant cloth 10 that can be folded up and down is fixed between the lifting platform 9 and the bottom of the accommodating tank 7. The parking platform 6 is also equipped with a thermal imaging sensor 11 for monitoring the bottom of the electric vehicle and a fan 12 for blowing on the bottom of the electric vehicle. The camera 2, charging gun, transformer assembly 4, electronic control system, electric telescopic mechanism, thermal imaging sensor 11 and fan 12 are electrically connected.

[0030] When in use, the parking platform 6 is buried in the parking space so that the top of the parking platform 6 is flush with the ground of the parking space. Under normal circumstances, the lifting platform 9 is lowered to block the receiving slot 7. When the vehicle is parked on the top of the parking platform 6, the camera 2 automatically recognizes the license plate, and thus obtains the basic information of the vehicle according to the database of the traffic management department, and can determine the charging voltage of the vehicle and the location of the battery pack. When the charging gun is connected to the vehicle and the charging is confirmed by the charging pile 1, the transformer component 4 outputs the corresponding voltage and charging can be carried out, thereby achieving the purpose of adaptive voltage regulation. Then the thermal imaging sensor 11 works to monitor the vehicle When the vehicle temperature is high, the fan 12 is started to dissipate heat from the bottom of the vehicle (the battery packs of electric vehicles on the market are mostly located close to the bottom of the vehicle). When increasing the current for fast charging, the fan 12 can also be actively controlled to work, thereby improving safety. When it is recognized that the vehicle temperature is higher than the safety threshold, the electronic control system controls the electric telescopic mechanism to extend, thereby raising the lifting platform 9 and unfolding the flame retardant cloth 10, thereby enclosing the vehicle, reducing the tendency of possible fire spread, reducing damage to surrounding facilities, and realizing fire protection function.

[0031] The electric telescopic mechanism includes a No. 1 sliding seat 13, a double-axis servo motor 14, a No. 1 screw 15, a No. 2 sliding seat 16, a No. 2 screw 17, a No. 3 sliding seat 18, a No. 4 sliding seat 19, a No. 1 shear-type connector 20, a No. 2 shear-type connector 21, a connecting rod 22, and a rivet 23. The front and rear parts of the accommodating slot 7 are each connected to two No. 1 sliding seats 13 for sliding left and right sliding, and the front and rear parts are each fixed with a double-axis servo motor 14 extending in the left and right directions. The rotating shaft of the double-axis servo motor 14 is coaxially fixed with a No. 1 screw 15. The thread rotation directions of the No. 1 screws 15 on the left and right sides of the double-axis servo motor 14 are opposite, and each of the No. 1 screws 15 is threadedly connected to each No. 1 sliding seat 13, so The left and right parts of the accommodating groove 7 are each connected to two No. 2 sliding seats 16 for sliding forward and backward sliding, and the left and right parts are each rotatably connected to a No. 2 screw rod 17 extending in the front and rear direction, and the external threads of the front and rear parts of the No. 2 screw rod 17 are rotated in opposite directions, and the front and rear parts of the No. 2 screw rod 17 are respectively threadedly connected to the No. 2 sliding seat 16, and the front and rear parts of the bottom end of the lifting platform 9 are each connected to two No. 3 sliding seats 18 for sliding forward and backward sliding, and the left and right parts of the bottom end are each connected to two No. 4 sliding seats 19 for sliding forward and backward sliding, and a No. 1 shear-type connector 20 is commonly installed between the No. 1 sliding seat 13 and the No. 3 sliding seat 18, and a No. 2 shear connector 21 is commonly installed between the No. 2 sliding seat 16 and the No. 4 sliding seat 19. The No. 1 shear connector 20 and the No. 2 shear connector 21 are respectively composed of two connecting rods 22 and a rivet 23. The middle parts of the two connecting rods 22 are shear-hinged to each other through the rivet 23. The bottoms of the two connecting rods 22 in the No. 1 shear connector 20 are respectively hinged to the No. 1 sliding seat 13, and the tops of the two connecting rods 22 in the No. 1 shear connector 20 are respectively hinged to the No. 3 sliding seat 18. The bottoms of the two connecting rods 22 in the No. 2 shear connector 21 are respectively hinged to the No. 2 sliding seat 16, and the tops of the two connecting rods 22 in the No. 2 shear connector 21 are respectively hinged to the No. 4 sliding seat 19. The dual-axis servo motor 14 is electrically connected to the electronic control system. The dual-axis The No. 1 screw rod 15 and the No. 2 screw rod 17 on the left and right sides of the servo motor 14 are connected for transmission through the meshing of bevel gears. When the dual-axis servo motor 14 rotates forward and backward, the No. 1 sliding seat 13 on the left and right sides can be brought closer to and away from each other through the No. 1 screw rod 15, and when it rotates forward and backward, the No. 2 sliding seat 16 on the left and right sides can be brought closer to and away from each other through the bevel gear and the No. 2 screw rod 17. When the dual-axis servo motor 14 rotates forward and backward, the No. 1 screw rod 15, bevel gear, No. 2 screw rod 17, No. 1 sliding seat 13, No. 2 sliding seat 16, No. 1 shear-type connector 20, No. 2 shear-type connector 21, No. 3 sliding seat 18 and No. 4 sliding seat 19 can make the lifting platform 9 move up and down.

[0032] Under normal circumstances, the dual-axis servo motor 14 rotates forward, and through the No. 1 screw rod 15, the bevel gear and the No. 2 screw rod 17, the No. 1 sliding seats 13 are moved away from each other and the No. 2 sliding seats 16 are moved away from each other, thereby lowering the lifting platform 9 through the No. 1 shear type connector 20 and the No. 2 shear type connector 21. On the contrary, by controlling the dual-axis servo motor 14 to reverse, through the No. 1 screw rod 15, the bevel gear and the No. 2 screw rod 17, the No. 1 sliding seats 13 are moved closer to each other and the No. 2 sliding seats 16 are moved closer to each other, thereby raising the lifting platform 9 through the No. 1 shear type connector 20 and the No. 2 shear type connector 21.

[0033] A water tank 24 is provided in the lifting platform 9. The middle part of the water tank 24 is connected to the middle part of the accommodating tank 7 through a water outlet 75. The flame retardant cloth 10 is breathable and water-absorbent. The upper part of the flame retardant cloth 10 is more breathable than the middle and lower parts (it can be formed by splicing and sewing flame retardant cloths 10 with different breathability effects). A drain outlet 25 connected to the external drainage system is provided on the upper part of the water tank 24.

[0034] Furthermore, when the electric vehicle is normally charged, in order to further improve the heat dissipation effect, the lifting platform 9 can be slightly extended through the electric telescopic mechanism. At this time, the upper part of the flame-retardant cloth 10 is exposed to the outside world, and heat exchange can be carried out with the outside world. Since the flame-retardant cloth 10 is breathable and water-absorbent, when it absorbs the moisture in the holding tank 7, it can allow the surrounding air to take away the moisture as it passes through, thereby cooling the surrounding air and increasing the humidity. When this part of the air passes through the vehicle, it can better dissipate heat and enhance the auxiliary heat dissipation effect. The water in the holding tank 7 can be filled in advance and can also enter the water tank 24, thereby increasing the water storage capacity, and the excess water can be discharged through the drain port 25.

[0035] The number of the flame-retardant cloths 10 is two, and the No. 1 shear-type connector 20 and the No. 2 shear-type connector 21 are both located in the gap between the two flame-retardant cloths 10.

The No. 1 support roller 28 and the No. 2 support roller 29 are respectively penetrated by a collecting trough 30 at the top and bottom, and an arc-shaped and hollow mesh plate 31 is fixed to one end of the collecting trough 30 near the outer circumference of the No. 1 support roller 28 and the No. 2 support roller 29. The mesh plate 31 is flush with the outer circumference of the No. 1 support roller 28 or the No. 2 support roller 29. The support platform 26 is penetrated by a through opening 32 at the top and bottom. The outer circumference of the No. 1 support roller 28 and the outer circumference of the No. 2 support roller 29 can respectively leak out of the opening 32 and can block the opening 32. The opening 32 can be connected to the collection tank 30. A plurality of support plates 33 arranged in the axial direction are fixed in the collection tank 30. The upper part of each support plate 33 is fixed to the bottom of the mesh plate 31 respectively. The No. 1 support roller 28 and the No. 2 support roller 29 are coaxially fixed with bevel gears. The two diagonal parts of the support platform 26 are respectively fixed with a vertical No. 1 servo motor 34. The rotating shafts of the two No. 1 servo motors 34 are coaxially fixed with bevel gears. The rotating shaft of the No. 1 servo motor 34 is connected to the No. 1 support roller 28 and the No. 2 support roller 29 through the meshing of the bevel gears for transmission. The No. 1 servo motor 34 is electrically connected to the electronic control system. The charging pile 1 is also equipped with a network module that is electrically connected to the electronic control system and connected to the external Internet.

[0036] Furthermore, when the device is used outdoors, when the network module obtains weather information and determines that it is raining, the No. 1 servo motor 34 is controlled to rotate, thereby driving the No. 1 support roller 28 and the No. 2 support roller 29 to rotate, so that the mesh plate 31 can block the opening 32. Then, rainwater flowing along the ground can pass through the mesh plate 31 through the collection trough 30 and the opening 32 and flow into the receiving tank 7 to replenish the water volume. The excess water is collected in the water tank 24 and then discharged from the drain outlet 25, achieving the effect of replenishing water. It not only saves energy and is environmentally friendly, but also maintains the water volume to a certain extent, thereby making the auxiliary heat dissipation effect more stable. In the case of non-rainfall, by controlling the No. 1 servo motor 34 to rotate, the outer circumference of the No. 1 support roller 28 and the outer circumference of the No. 2 support roller 29 block the opening 32, which can greatly reduce the entry of dust and other debris into the receiving tank 7, reducing the interference of dust and other debris on the device.

[0037] The No. 1 support roller 28 is fixed with a No. 1 water spray pipe 35 parallel to the axial direction, and the No. 2 support roller 29 is fixed with a No. 2 water spray pipe 36 parallel to the axial direction. The No. 1 support roller 28 and the No. 2 support roller 29 are respectively radially penetrated with a plurality of water spray holes 37, and the No. 1 water spray pipe 35 and the No. 2 water spray pipe 36 are respectively connected to the water spray holes 37. The No. 1 water spray pipe 35 penetrates the axial end of one of the No. 1 support roller 28 and is coaxially arranged with the No. 1 support roller 28 at the penetration portion. The No. 2 water spray pipe 36 penetrates the No. 2 support roller 29 at the axial end thereof. The axial end of the support platform 26 is coaxially arranged with the No. 2 support roller 29 at the through-position, and the other two diagonal positions of the support platform 26 are respectively fixed with connecting tees 38. The two through holes on the upper part of the connecting tee 38 are rotatably connected with the adjacent No. 1 water spray pipe 35 and No. 2 water spray pipe 36 respectively. The through hole at the bottom of the connecting tee 38 passes through the bottom end of the support platform 26. A submersible pump 39 is fixed at the bottom of the water tank 24. The drainage pipe of the submersible pump 39 is connected to the through hole at the bottom of the connecting tee 38 through a surplus hose, and is electrically connected to the electronic control system.

[0038] Furthermore, when assisting with heat dissipation or using flame-retardant cloth 10 to block a vehicle and slow the spread of a fire, the submersible pump 39 is controlled to pump water from the water tank 24 through the connecting tee 38, the first water spray pipe 35, and the second water spray pipe 36, ultimately spraying it out of the water spray hole 37. During this time, the first servo motor 34 is controlled to rotate back and forth, spraying the flame-retardant cloth 10 on both sides through the water spray hole 37, thereby increasing the moisture content of the flame-retardant cloth 10, enhancing the heat dissipation effect and delaying the spread of fire. When the flame-retardant cloth 10 is fully extended, its high moisture content significantly reduces its air permeability. At this time, if the electric vehicle burns and produces an open flame, the oxygen entering the surrounding area of the vehicle will be reduced, thereby achieving a flame retardant effect and improving the fire protection function.

[0039] The outer circumference of the No. 1 support roller 28 and the No. 2 support roller 29 is pasted with a reflective sticker 40 or fixed with a light strip 41. The light strip 41 can emit light of different colors to the outside world and is electrically connected to the electronic control system.

[0040] The reflective sticker 40 or the luminous light strip 41 can guide and warn the driver about the position of the parking platform 6 so that the driver can park the vehicle in the correct position.

[0041] The top of the parking platform 6 is provided with a horizontal mounting groove 42 along the front-to-back direction, and an annular support groove 43 is provided on the left and right ends of the inner wall of the mounting groove 42. The two support grooves 43 correspond to each other on the left and right sides. The front and rear parts of the mounting groove 42 are rotatably connected to rollers 44, and the two rollers 44 are jointly sleeved with a rubber conveyor belt 45. The rubber conveyor belt 45 is fixed with a plurality of annularly arranged support rods 46. The left and right parts of each support rod 46 are respectively slidably connected to the support groove 43. The parking platform 6 is also fixed with two The first servo motor 47 is fixed with the same axis as the supporting rod 46 of the second servo motor 47. A support cylinder 48 is fixed on the upper part of the rubber conveyor belt 45, and a groove 49 is opened on the top. The left and right parts of the groove 49 are respectively hinged with a cover plate 50, and are respectively connected to the support cylinder 48. A torsion spring is installed between the groove 49 and the cover plate 50. The two cover plates 50 can cover the groove 49 together. The cover plate 50 always has a tendency to cover the groove 49 under the elastic force of the torsion spring. The thermal imaging sensor 11 is located at the front and rear parts of the groove 49, the support cylinder 48 is connected to the lifting cylinder 51 by sliding up and down, and the front and rear parts are each fixed with an electromagnet 52, and the front and rear parts of the lifting cylinder 51 are each fixed with a permanent magnet 53, the permanent magnet 53 and the electromagnet 52 are aligned up and down, the second servo motor 47 and the electromagnet 52 are respectively electrically connected to the electric control system, and the electromagnet 52 can magnetically attract and repel the permanent magnet 53 when current in different directions is passed through it, thereby realizing the lifting cylinder 5 The lifting cylinder 51 moves up and down along the support cylinder 48. The upper portion of the lifting cylinder 51 is fixed to the fan 12, and a flexible connecting member 54 is fixed to the supporting cylinder 48 to prevent the lifting cylinder 51 from separating from the supporting cylinder 48. The connecting member 54 can be a rope or a chain. When the lifting cylinder 51 moves upward, it can push open the cover plate 50 to expose the fan 12. The bottom of the installation groove 42 and the water tank 24 are penetrated by a drainage hole 55. A gap is left between the rubber conveyor belt 45 and the installation groove 42 to allow rainwater to enter.

[0042] Furthermore, when camera 2 recognizes the license plate and obtains vehicle information, it can determine the position of the battery pack relative to the vehicle (battery packs of electric vehicles on the market are usually distributed in the front, middle, and rear parts). It can then control the second servo motor 47 to rotate accordingly, thereby using the rubber conveyor belt 45 to move the thermal imaging sensor 11 and the fan 12 to the corresponding position of the battery pack, thereby improving the temperature monitoring and heat dissipation effect of the battery pack. When idle, the electromagnet 52 is not energized, and the cover 50 is covered with the groove 49 under the elastic action of the torsion spring. When temperature monitoring or air cooling is required, the electromagnet 52 is energized to cause magnetic repulsion between the electromagnet 52 and the permanent magnet 53, thereby causing the lifting cylinder 51 to push the cover 50 to expand and extend from the support cylinder 48, so that it can be closer to the bottom of the vehicle and away from the ground. After the fan 12 is activated, air cooling can be carried out. When it needs to be retracted, the electromagnet 52 and the permanent magnet 53 are controlled to produce magnetic attraction. Rainwater entering the installation groove 42 can be discharged into the water tank 24 through the drainage hole 55.

[0043] The charging gun is electrically connected to the electronic control system via a charging cable 56 , and the charging cable 56 is electrically connected to the electronic control system via a connector 57 . The connector 57 can be automatically and completely disconnected and separated after being triggered.

[0044] The connector 57 includes a socket 58, a plug 59, an electric push rod 60, a front through hole 61, a conductive tube 62, a slot 63, a main compression spring 64, a plug 65, a socket 66, a conductive rod 67, and an elastic member 68. The socket 58 is fixed to the charging pile 1 and electrically connected to the electronic control system. The plug 59 is electrically connected and fixed to the charging line 56. A vertical electric push rod 60 is fixed to the bottom of the socket 58. A plurality of front through holes 61 extending in the front-to-back direction are opened at the front end of the socket 58. A conductive tube 62 is fixed in the rear part of each of the front through holes 61. A slot 63 extending in the front-to-back direction is opened at the front end of the socket 58. The push rod of the electric push rod 60 is plugged into the slot 63 with a gap. A main compression spring 64 is fixed to the rear end of the slot 63, and an insertion rod 65 extending in the front-to-back direction is fixed to the rear of the plug 59. A socket 66 is passed through the insertion rod 65 from top to bottom. The socket 66 can be connected to the push rod of the electric push rod 60, and can squeeze the main compression spring 64 and insert it into the slot 63. A plurality of conductive rods 67 are fixed to the rear of the plug 59. Each of the conductive rods 67 can be respectively connected to the conductive tube 62 in the front and back phases to achieve electrical connection, and is respectively electrically connected to the charging line 56. A conductive elastic part 68 is respectively fixed in each of the conductive tubes 62, and is respectively electrically connected to the electric control system. When the conductive rod 67 is inserted into the conductive tube 62, it can contact the elastic part 68 to achieve electrical connection.

[0045] During normal use, the push rod of the electric push rod 60 is plugged into the socket 66. At this time, the main compression spring 64 is pushed by the plug rod 65 and is in an elastic contraction state. The conductive rod 67 is electrically connected to the conductive tube 62. When the thermal imaging sensor 11 senses that the battery pack temperature exceeds the safety threshold, the electric push rod 60 retracts. At this time, under the elastic repulsive force of the main compression spring 64, the plug 65 is disengaged from the slot 63, thereby disengaging the plug 59 from the socket 58, that is, the conductive rod 67 is disengaged from the conductive tube 62, thereby blocking the risk of fire spreading along the charging line 56 to the charging pile 1, improving the fire protection function and reducing economic losses.

[0046] The connector 57 also includes a guide groove 69, an upper partition 70, a lower partition 71, a secondary compression spring 72, a rear through hole 73, and a shell 74. The front part of the socket 58 is penetrated by a guide groove 69, and the guide groove 69 is slidably connected to the upper partition 70 and the lower partition 71 up and down, and penetrates each front through hole 61 up and down. The upper partition 70 and the lower partition 71 are respectively fixed to the socket 58 with a secondary compression spring 72. The upper partition 70 has a tendency to move upward along the guide groove 69 under the elastic repulsive force of the secondary compression spring 72, and the lower partition 71 has a tendency to move downward under the elastic repulsive force of the secondary compression spring 72. The bottoms of the upper and lower partitions 71 are chamfered and tilted backward. Rear through-holes 73 are respectively passed through the upper and lower partitions 70 and 71. A housing 74 is fixed to the rear of the plug 59. Under the elastic repulsive force of the secondary compression spring 72, the upper and lower partitions 70 and 71 can extend from the guide slots 69 and fully shield the conductive tubes 62. The upper and lower partitions 70 and 71 can be squeezed by the housing 74 and retracted into the guide slots 69, so that the front through-holes 61 and the rear through-holes 73 are aligned front to back. The conductive rod 67 can pass through the front through-holes 61 and the rear through-holes 73 and then be plugged into the conductive tube 62 to achieve electrical connection.

[0047] Furthermore, when the plug 59 is disengaged from the socket 58, under the elastic repulsive force of the secondary compression spring 72, the upper partition 70 and the lower partition 71 move away from each other to block the rear heat-conducting tube, thereby preventing moisture from entering the conductive tube 62 and causing a short circuit during firefighting, thereby improving the fire protection effect. When the plug 59 is re-plugged into the socket 58, the shell 74 squeezes the upper partition 70 and the lower partition 71, thereby aligning the front through hole 61 with the rear through hole 73, and then the conductive rod 67 can be easily plugged into the conductive tube 62. After the plug 65 is fully plugged into the slot 63, the electric push rod 60 can be controlled to extend the push rod.
