Description

Technical Field

[0001] The present invention belongs to the technical field of charging station parking space equipment, and particularly relates to an intelligent ground lock system for charging parking spaces in social charging stations. Background Art

[0002] In current society, the charging parking spaces in public parking lots are often occupied by fuel vehicles, which seriously affects the normal operation of new energy vehicle charging stations. Some charging parking spaces use a ground lock system combined with license plate recognition technology to distinguish vehicles, and only allow new energy vehicles to enter and park for charging. However, some new energy vehicle owners do not charge or park for a long time with short charging, which further intensifies the tension of parking space resources. This is a major challenge and trouble for operators.

[0003] To solve this problem, the ground lock system has been further upgraded. When a new energy vehicle is recognized to enter, the ground lock will rise to close the parking space, and at the same time, a parking space occupancy fee will be charged within the period when the vehicle does not charge or charges for a short time. This measure has improved the occupancy efficiency of parking spaces to a certain extent, but also brought some unforeseen safety hazards.

[0004] Since some new energy vehicle owners rest in the vehicle without getting off or the line of sight is blocked due to the vehicle engine compartment, they cannot perceive that the ground lock has risen. Once the vehicle starts, it will collide with the ground lock, causing damage to the ground lock and even possibly scratching the battery of the new energy vehicle, thus triggering battery fires, vehicle damage, and even causing serious consequences such as casualties. Such accidents will not only damage the equipment of the charging station, but also may ignite the vehicles in adjacent parking spaces, triggering a chain of accidents, resulting in more economic losses and risks of casualties.

[0005] Therefore, in view of the above technical problems, it is necessary to provide an intelligent ground lock system for charging parking spaces in social charging stations.

[0034] In order to enable those skilled in the art of this technology to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0035] As Figures 1 to 6 shown, in an intelligent ground lock system for a charging space in a social charging station in an embodiment of the present invention, the charging space includes a substrate 1 and a power supply box 34. A charging cable 37 is installed on the power supply box 34, and a charging gun 372 is installed at one end of the charging cable 37 away from the power supply box 34. The height of the substrate 1 matches the height of the internal road of the charging station. The intelligent ground lock system includes a first protective shell 8, and the first protective shell 8 is fixedly installed on the substrate 1. A double-column motor 9 is installed inside the first protective shell 8, a lock rod 14 is welded on the rotating shaft of the double-column motor 9, the lock rod 14 penetrates through the opposite side walls of the first protective shell 8, a fixing plate 15 is welded on the lock rod 14, and a first vision sensor 16 is installed on the fixing plate 15. A processor 27 is also installed inside the first protective shell 8, and the first protective shell 8 communicates with the first vision sensor 16.

[0036] Specifically, before the vehicle approaches the parking space, the first visual sensor 16 scans the license plate information, and the processor 27 determines whether the vehicle is a new energy vehicle. If so, the processor 27 sends an instruction to control the double-column motor 9 to start. After the double-column motor 9 starts, it drives the lock rod 14 to rotate, so that the lock rod 14 is parallel to the base 1, and the vehicle can enter the charging parking space. After the vehicle enters the charging parking space, the processor 27 controls the double-column motor 9 to start again, so that the lock rod 14 rotates to be perpendicular to the base 1, and the charging parking space is closed. At this time, if the vehicle in the charging parking space is short-distance and long-stopped or not occupied by charging, it is necessary to pay the parking space occupation fee by scanning the code. If the fee is not paid, the lock rod 14 will not rotate, and the vehicle cannot leave the parking space normally. The above are all existing technologies and will not be elaborated in detail.

[0037] When the driver is sitting in the car, due to the limitations of the front cabin and rearview mirrors, there is a visual blind spot around the car body and it is not easy to find the lock rod 14. If the driver is not familiar with the operation mechanism of the intelligent ground lock system of the charging parking space of the social charging station and starts the vehicle without paying the parking space occupation fee, the vehicle will hit the lock rod 14, which may cause damage to the vehicle and the intelligent ground lock system, or even scratch the vehicle chassis by the lock rod 14, causing the battery installed on the vehicle chassis to rupture and cause a fire, causing serious economic losses and threatening the life safety of the driver. The fire may also ignite the vehicles in the adjacent charging parking spaces, further increasing the risk of economic losses and casualties.

[0038] In order to solve the above problems, Figures 3 to 10 As shown, a cavity 101 and a first opening 102 are provided on the base 1, and a pair of first fixed blocks 3 are provided in the cavity 101, and the pair of first fixed blocks 3 are symmetrically welded in the cavity 101. A pair of slideways 4 are provided on the first fixed block 3, and a sliding block 6 is slidably connected in the slideway 4. A rack 5 is welded at one end of the sliding block 6, and a plurality of first wedge blocks 7 are integrally formed on the upper end surface of the sliding block 6. A plurality of second wedge blocks 19 matching the first wedge blocks 7 are slidably connected to the sliding block 6, and a connecting column 191 is welded on the plurality of second wedge blocks 19, and a pair of connecting columns 191 are rotatably connected to rollers 20. A bearing plate 21 is covered on the first opening 102, and the tires of the vehicle are pressed on the bearing plate 21 after the vehicle enters the charging parking space, and the bearing plate 21 plays a bearing role for the vehicle. The bearing plate 21 is provided with through slots 22 matching the rollers 20 , and the provision of the through slots 22 does not affect the strength of the bearing plate 21 , that is, even if a plurality of through slots 22 are provided on the bearing plate 21 , the bearing plate 21 can still bear the weight of the vehicle.

[0039] A transmission assembly is also installed in the cavity 101, which is used to realize the sliding of the sliding block 6 in the slide 4. When the sliding block 6 slides in the slide 4, it can lift the roller 20 upward. The roller 20 is lifted so that it can protrude from the through groove 22 to the upper end surface of the supporting plate 21, thereby lifting the vehicle on the supporting plate 21.

[0040] The transmission assembly includes a second fixed block 12, a rotating rod 121 is transmission-connected to the second fixed block 12, a pair of second gears 11 are welded to the rotating rod 121, a first gear 10 matching the second gear 11 is fixedly connected to the lock rod 14, a second opening 103 matching the first gear 10 is opened on the base 1, the first gear 10 passes through the second opening 103 and meshes with the second gear 11. A third gear 13 meshing with the rack 5 is welded to the rotating rod 121.

[0041] Specifically, when the charging parking space is closed, the locking rod 14 and the bearing plate 21 are perpendicular to each other. At this time, the second wedge block 19 is above the first wedge block 7 , and the roller 20 leaks out of the through groove 22 and protrudes from the upper end surface of the bearing plate 21 .

[0042] When the first visual sensor 16 recognizes that the vehicle in front is a new energy vehicle, the processor 27 controls the double-column motor 9 to rotate clockwise, and the double-column motor 9 drives the lock rod 14 to rotate when it rotates. When the lock rod 14 rotates, the first gear 10 on the lock rod 14 also rotates. The meshing rotation of the first gear 10 and the second gear 11 will drive the rotating rod 121 to rotate, so that the third gear 13 on the rotating rod 121 will also rotate. When the third gear 13 rotates, it meshes with the rack 5, so that the rack 5 and the sliding block 6 slide to the right in the slide 4, and the second wedge block 19 gradually slides from the end face of the first wedge block 7 to the sliding block 6. In the process of the second wedge block 19 sliding onto the sliding block 6, the height of the connecting column 191 and the roller 20 is reduced, and the roller 20 will be lower than the upper end face of the bearing plate 21 and enter the through groove 22. In this way, the vehicle can normally drive into the charging parking space and park on the bearing plate 21.

[0043] When the vehicle is parked on the load-bearing plate 21, the double-column motor 9 rotates counterclockwise to make the locking rod 14 perpendicular to the load-bearing plate 21. In this process, the third gear 13 and the rack 5 are meshed and transmitted, and the rack 5 and the sliding block 6 slide to the left in the slideway 4. During the sliding process of the sliding block 6, the first wedge block 7 and the second wedge block 19 are wedge-shaped, and the second wedge block 19 will slide to the top of the first wedge block 7, and the height of the second wedge block 19 will be increased, and the connecting column 191 will be lifted upward, and the roller 20 connected to the connecting column 191 will protrude from the upper end surface of the load-bearing plate 21 again, and the roller 20 will lift the vehicle parked on the load-bearing plate 21, and the tires of the vehicle are located on multiple rollers 20.

[0044] At this time, if the driver starts the vehicle without paying the parking space occupancy fee, the roller 20 will also rotate when the vehicle tire rotates. The vehicle tire idles above the roller 20 and the vehicle position does not change, which can prevent the vehicle from hitting the lock rod 14. An inductor matching the microphone 17 is installed on the rotating shaft of the roller 20. When the microphone 17 receives the idling information of the roller 20, it will emit a sound to remind the driver to pay the parking space occupancy fee. After the driver pays the fee, the lock rod 14 rotates clockwise, the roller 20 falls into the through groove 22, and the vehicle tire presses on the bearing plate 21, so that the vehicle can drive out of the parking space normally.

[0045] Preferably, when the roller 20 falls into the through groove 22, the outer contour of the roller 20 is 2-8 mm lower than the upper end surface of the bearing plate 21. The upper half of the roller 20 will still be in the through groove 22, and the through groove 22 restricts the movement of the roller 20 to prevent the roller 20 from detaching from the through groove 22 due to the friction between the first wedge block 7 and the second wedge block 19.

[0046] Furthermore, since most current social charging stations are built in open areas, the parking space is exposed to the sun in hot summer, which will cause the temperature of the bearing plate 21 to be relatively high. At the same time, a large amount of heat is generated by the battery of the new energy electric vehicle itself during driving. During the continuous driving of the vehicle, the relative movement between the vehicle itself and the air can dissipate heat from the battery. However, after the vehicle is parked in the charging parking space, the heat accumulates around the battery. Coupled with the heat generated during battery charging, the accumulation of these three kinds of heat will cause the battery to self-protect thermally, and it is easy to have the phenomenon of the charging gun jumping during charging, which prolongs the vehicle charging time, and in severe cases, it will increase the occurrence of battery fires.

[0047] To solve the above problems, as Figure 2 、 Figure 4 、 Figure 8 and Figure 10 shown, a water storage tank 104 is formed between a pair of first fixing blocks 3. The water storage tank 104 stores water, and through holes 23 matching the water storage tank 104 are opened on the bearing plate 21. A second partition plate 33 is welded in the cavity 101. The second partition plate 33 seals the water storage tank 104 so that the water in the water storage tank 104 does not affect the transmission component. In hot summer, the evaporation of the water in the water storage tank 104 can absorb heat, making the temperature in the water storage tank 104 relatively low. The lower temperature is transmitted to the surface of the bearing plate 21 through the through holes 23, reducing the temperature of the surface of the bearing plate 21 and cooling the charging vehicle parked on the bearing plate 21.

[0048] Furthermore, a hair dryer 26 is installed in the first protective shell 8. An air outlet pipe 261 and an air suction pipe 262 are installed on the hair dryer 26. The air outlet pipe 261 penetrates through the first protective shell 8, and the nozzle of the air outlet pipe 261 faces the through hole 23. The nozzle of the air suction pipe 262 is communicated with the water storage tank 104.

[0049] Specifically, when the temperature is relatively high in summer and there is a charging vehicle parked on the carrier plate 21, the hair dryer 26 will start, extracting the relatively cool air in the water storage tank 104 and blowing it towards the vehicle chassis to cool the charging vehicle. This can not only prevent the battery temperature from being too high and causing the charging gun to trip, ensuring the charging efficiency of the vehicle, but also prevent fires caused by abnormal battery temperature.

[0050] Furthermore, the upper end surface of the first fixing block 3 has a slope, and the slope of the upper end surface of the first fixing block 3 slopes towards the water storage tank 104. In case of rain, the rainwater that enters the cavity 101 from the through groove 22 will first fall on the first fixing block 3, and the rainwater on the first fixing block 3 will be diverted into the water storage tank 104, reducing the frequency of adding water to the water storage tank 104 and saving water resources.

[0051] In addition, in order to prevent the water in the water storage tank 104 from being excessive, a drain opening 2 matching the water storage tank 104 is provided on the rear panel of the base body 1, and the drain opening 2 is lower than the upper end surface of the first fixing block 3. When the water in the water storage tank 104 is excessive, it will drain out from the drain opening 2 and flow into the urban drainage system.

[0052] Even further, a placement groove 24 matching the air outlet pipe 261 is provided on the carrier plate 21, and a wind guiding surface 25 is provided on the placement groove 24. Specifically, the wind blown out from the pipe orifice of the air outlet pipe 261 will blow on the wind guiding surface 25. After being guided by the wind guiding surface 25, the wind blown out from the air outlet pipe 261 will blow on the vehicle chassis, increasing the heat dissipation effect on the vehicle chassis. At the same time, because the air flow rate between the vehicle chassis and the carrier plate 21 is accelerated and the air pressure becomes smaller, the relatively cool air in the water storage tank 104 will flow out from the through holes 23, reducing the air temperature below the vehicle chassis. After the air in the water storage tank 104 flows out, the air pressure in the water storage tank 104 will also decrease. At this time, the air in the urban drainage system will flow into the water storage tank 104 from the drain opening 2, further reducing the air temperature in the water storage tank 104 and achieving a better cooling effect on the vehicle chassis.

[0053] It should be noted that there have been many reported cases of new energy vehicle charging fires in society, and the vehicles parked in adjacent parking spaces have been ignited, causing significant economic losses. This is mainly caused by internal short circuits in the battery during charging.

[0054] To prevent the vehicles parked in adjacent parking spaces from being ignited when a new energy vehicle catches fire during charging. As Figures 1 to 7As shown, a second protective case 35 and a second vision sensor 40 are installed on the power supply box 34, and the second vision sensor 40 communicates with the processor 27. A first rotary motor 29 is installed on the first fixing block 3. A first belt 30 is installed on the transmission shaft of the first rotary motor 29. A pulley 32 matching the first belt 30 is welded on the rotating shaft of the roller 20 at the end away from the water storage tank 104. One end of the first belt 30 away from the first rotary motor 29 is installed on the pulley 32, and a second belt 321 is also installed on two adjacent pulleys 32.

[0055] Specifically, when a new energy vehicle catches fire in the charging space, the second vision sensor 40 sends the vehicle fire information into the processor 27, and the processor 27 issues an instruction to make the double-column motor 9 rotate to drive the lock rod 14 to rotate to the position as shown in Figure 7 As shown. At this time, the distance between the lock rod 14 and the highest point of the bearing plate 21 is slightly lower than the vehicle chassis, and the second wedge block 19 is still located on the upper end surface of the first wedge block 7, and the vehicle tires are on the rollers 20. Because the power system on the vehicle will be cut off after the new energy vehicle catches fire and the electronic handbrake will fail, the first rotary motor 29 is started at this time to drive the roller 20 to rotate clockwise, and the vehicle tires rotate counterclockwise on the rollers 20. When the first rotary motor 29 reaches a certain speed, the double-column motor 9 rotates clockwise again to make the lock rod 14 parallel to the bearing plate 21, and the second wedge block 19 slides off the first wedge block 7 onto the sliding block 6, and the roller 20 descends into the through groove 22, and the vehicle tires fall on the bearing plate 21. The inertia of the rotation of the vehicle tires will drive the vehicle to move forward, so that the vehicle drives out of the parking space and away from the adjacent parking spaces, so that the vehicles in the adjacent parking spaces will not be ignited.

[0056] In addition, because the vehicle tires rotate rapidly, they will slip when contacting the bearing plate 21. The through grooves 22 opened on the bearing plate 21 can also strengthen the friction between the vehicle tires and the bearing plate 21 to ensure that the vehicle can drive out of the bearing plate 21 smoothly.

[0057] It should be noted that some new energy vehicles use a mechanical handbrake, and the mechanical handbrake is still effective after the battery catches fire, and the vehicle cannot be moved out of the parking space by the above method.

[0058] As is well known, the mechanical handbrake of current civilian vehicles all acts on the rear wheels. Therefore, only when it is recognized that the tail of the new energy vehicle is about to reverse into the charging bay will the processor 27 control the unlocking lever 14 to open. When the vehicle battery catches fire in the charging bay, the rollers 20 rotate clockwise. Since the rear wheels of the vehicle are locked by the handbrake and cannot rotate, the vehicle will move towards the power supply box 34 on multiple rollers 20. At this time, the second vision sensor 40 judges the change in the vehicle position and sends the information to the processor 27. The processor 27 issues an instruction to reverse the first rotary motor 29, so that the rollers 20 rotate counterclockwise, and the vehicle on the rollers 20 can be gradually moved out.

[0059] When the rear wheels of the vehicle disengage from the rollers 20, the rollers 20 no longer act on the vehicle tires. At this time, the rear wheels of the vehicle are located on the bearing plate 21. The processor 27 issues an instruction to rotate the double-column motor 9 counterclockwise. The unlocking lever 14 rotates counterclockwise and abuts against the chassis of the vehicle. As the unlocking lever 14 rotates counterclockwise, the rear wheels of the vehicle are lifted up, and at this time the rear wheels of the vehicle are in a suspended state. Since the handbrake does not act on the front wheels of the vehicle, the front wheels of the vehicle can rotate normally. As the unlocking lever 14 continues to rotate counterclockwise, under the action of gravity, the front wheels of the vehicle rotate on the road, and the vehicle is gradually moved out of the charging bay, and will be far away from the vehicles in the adjacent charging bays, preventing the vehicles in the adjacent charging bays from being ignited.

[0060] Furthermore, a flexible wheel 18 is installed on the unlocking lever 14. The flexible wheel 18 can increase the contact area and friction between the unlocking lever 14 and the vehicle chassis, prevent slipping between the vehicle chassis and the unlocking lever 14, and ensure that the vehicle can be smoothly moved out of the charging bay.

[0061] Moreover, by setting the number and position of the rollers 20, the position of the rollers 20 is matched with the length of the unlocking lever 14. When the vehicle tires disengage from the rollers 20, the support frame of the vehicle tires is exactly above the horizontal rod body of the unlocking lever 14, which is more conducive to lifting the rear wheels of the vehicle. In addition, the number of rollers 20 can also be increased. When the vehicle tires disengage from the rollers 20, the vehicle tires will fall on the internal road of the social charging station. At this time, the unlocking lever 14 rotates counterclockwise to also push the vehicle, accelerating the speed at which the burning vehicle moves away from the charging bay.

[0062] In addition, a first partition plate 31 is welded to the first fixing block 3. One end of the first partition plate 31 far from the first fixing block 3 is connected to the bearing plate 21. A belt opening 311 matching the first belt 30 is formed on the first partition plate 31. The first partition plate 31 plays a protective role for the first rotary motor 29, preventing the rainwater on the first fixing block 3 from contacting the first rotary motor 29.

[0063] Such as Figure 1 and Figure 12As shown in the figure, a second protective shell 35 is installed on the power supply box 34. An interface 36 and a second rotary motor 38 are installed inside the second protective shell 35. The charging cable 37 is plugged into the interface 36. A fixing ring 371 is bonded to the charging cable 37. A pressing plate 381 matching the fixing ring 371 is welded on the rotating shaft of the second rotary motor 38.

[0064] Specifically, when the second vision sensor 40 detects that the vehicle is on fire, the rotating shaft of the second rotary motor 38 rotates. After the pressing plate 381 moves away from the fixing ring 371, the power supply box 34 cuts off its own power. During the process of the vehicle on fire being removed from the charging position, the vehicle drags the charging gun 372, and the charging cable 37 will fall off from the interface 36, without affecting the removal of the vehicle.

[0065] A water baffle 39 is plugged on the second protective shell 35. A plug body 391 is bonded to the water baffle 39. The water baffle 39 is plugged into the second protective shell 35 through the plug body 391. Under normal conditions, the water baffle 39 can play a role in preventing rain. When an external force acts on the charging cable 37, the water baffle 39 will also move away from the second protective shell 35, without blocking the charging cable 37 from detaching from the interface 36.

[0066] As Figure 6 and Figure 7 shown in the figure, a booster pump 28 is installed inside the first protective shell 8. A water inlet pipe 281 and a high-pressure nozzle 282 are installed on the booster pump 28. The water inlet pipe 281 is connected to the fire-fighting water supply pipeline in the charging station. The high-pressure nozzle 282 penetrates through the first protective shell 8 and faces the road surface. After the vehicle on fire in the charging position is removed, the booster pump 28 is started, and the high-pressure nozzle 282 sprays water to extinguish the vehicle on fire. Moreover, the booster pumps 28 on the adjacent positions will also be started, so that the high-pressure nozzles 282 spray a water curtain to prevent the vehicles in the positions from being threatened by the flames and high temperature.

[0067] During use, as Figures 1 to 8 shown in the figure, when a new energy vehicle enters the charging position, the double-column motor 9 drives the locking rod 14 to rotate. When the locking rod 14 rotates to be parallel to the bearing plate 21, the roller 20 falls into the through groove 22, and the vehicle can normally drive into the charging position and will stop on the bearing plate 21.

[0068] After the vehicle is parked in place, the double-column motor 9 drives the lock rod 14 to rotate. The lock rod 14 is perpendicular to the bearing plate 21 to close the charging parking space. When the lock rod 14 rotates, the first gear 10 also rotates accordingly. After the first gear 10 meshes with the second gear 11, the rotating rod 121 rotates. When the rotating rod 121 rotates, the third gear 13 on the rotating rod 121 meshes with the rack 5. The rack 5 and the sliding block 6 slide in the slideway 4. After the first wedge block 7 and the second wedge block 19 are in wedge fit, the second wedge block 19 is located above the first wedge block 7, causing the roller 20 to rise and lift the vehicle on the bearing plate 21. When the vehicle is started with the lock rod 14 in the lowered position, the vehicle tires will spin idly above the roller 20, and the vehicle cannot move, protecting the vehicle and the ground lock system and preventing the vehicle from colliding with the lock rod 14.

[0069] When the vehicle is charging, the hair dryer 26 extracts the air with a lower temperature in the water storage tank 104 to cool the bottom of the vehicle, preventing the vehicle battery from overheating and causing the charging gun to jump. While ensuring the charging efficiency, it can also prevent the vehicle battery from overheating and catching fire.

[0070] If the vehicle battery is short-circuited and the vehicle catches fire, the rotation of the roller 20 and the lock rod 14 can move the vehicle out of the charging parking space to prevent the vehicle in the adjacent parking space from being ignited. At the same time, the booster pump 28 can extinguish the fire on the burning vehicle to prevent further expansion of the loss.

[0071] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
