Description

Technical Field

[0001] This invention belongs to the field of new energy vehicle charging pile technology, specifically, it relates to a safe and anti-theft charging pile for new energy vehicles. Background Technology

[0002] New energy vehicle charging piles refer to equipment that provides charging services for plug-in new energy vehicles. Their power input end is connected to the AC power grid, and their power output end is connected to the vehicle through a charging plug to realize the charging function. With the vigorous development of the new energy vehicle industry, the number of charging piles, as an important infrastructure, is constantly increasing. In the existing technology, the installation, fixing and anti-theft of charging piles face many problems.

[0003] Currently, most charging stations are fixed to the ground with bolts. This method exposes the fixing components, making them easy for criminals to damage and dismantle. Furthermore, existing anti-theft measures for charging stations are relatively inadequate, typically consisting of only a single camera. However, cameras can only serve as post-theft monitoring and evidence collection; they cannot prevent theft in real time. Once a charging station is stolen, it not only causes direct economic losses to operators but also affects the normal use of the service by new energy vehicle users, reducing the convenience and reliability of public charging services and negatively impacting the healthy development of the new energy vehicle industry. Therefore, this invention is proposed to address these issues. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a safe and anti-theft charging pile for new energy vehicles that can overcome or at least partially solve the above problems.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: a safe and anti-theft charging pile for new energy vehicles, including a charging pile housing, an equipment cavity provided inside the charging pile housing, a charging device installed inside the equipment cavity, a charging gun electrically connected to the charging device via a charging cable, the charging gun being inserted into the charging pile housing, a roof fixedly connected to the upper end of the charging pile housing via a support rod, the charging pile housing sitting in a groove opened in a concrete layer, a limiting cavity opened below the equipment cavity inside the charging pile housing, and further including: a rotating shaft rotatably connected in the limiting cavity; an electric... A motor is fixedly connected to the outer wall of the charging pile housing near the limiting cavity, with the output end of the motor fixedly connected to the end adjacent to the rotating shaft; a support rod is symmetrically fixedly connected in the limiting cavity and located on both sides of the rotating shaft; a drive gear is fixedly connected to the rotating shaft; a toothed plate is slidably connected to the support rod via a T-shaped slider, with the toothed plates on the two support rods symmetrically distributed and both meshing with the drive gear; a limiting insert is fixedly connected to the end of the toothed plate, with the end of the limiting insert extending out of the limiting cavity away from the toothed plate, and a limiting slot for cooperating with the limiting insert is provided on the groove wall of the groove.

[0006] To facilitate sealing the gap between the charging pile housing and the groove opening, an air supply airbag is fixedly connected inside the limiting slot, and a sealing airbag ring is fixedly connected to the opening of the groove. The air supply airbag and the sealing airbag ring are connected by a connecting air pipe.

[0007] To facilitate real-time monitoring of the air pressure inside the sealing airbag ring, a pressure sensor is further fixedly connected inside the sealing airbag ring.

[0008] To further improve the smoothness of adjusting the position of the charging pile housing, two sets of rollers are symmetrically installed at the bottom of the charging pile housing, and the rollers roll in the groove.

[0009] To facilitate a realistic simulation of a charging pile catching fire, the charging pile housing further includes an air chamber located above the equipment cavity, in which a blower is installed. Symmetrically arranged on both sides of the air chamber are storage chambers containing smoke oil. An electric heating plate is fixedly installed at the lower end of each storage chamber. A liquid inlet connected to the storage chamber is located on the charging pile housing, and a one-way valve is installed in the liquid inlet. The air chamber and storage chamber are connected via a port. Multiple exhaust ports connected to the air chamber are equidistantly spaced at the upper end of the charging pile housing, and electromagnetic valves are installed at each exhaust port.

[0010] To ensure more even heating of the e-liquid, the upper end of the charging pile housing is provided with an air outlet pipe, and the lower end of the air outlet pipe is provided with an air inlet that connects to the exhaust port. A drive rod is vertically rotatably connected to the upper end of the charging pile housing near the storage cavity. Multiple drive blades are fixedly connected at equal intervals around the side of the drive rod extending upward into the air outlet pipe. A rotating rod is fixedly connected to the end of the drive rod extending downward into the storage cavity. Multiple rows of stirring rods are fixedly connected at equal intervals at the position of the rotating rod in the e-liquid.

[0011] To further shorten the time it takes for the aerosol oil to produce smoke, both the rotating rod and the stirring rod are heat-conducting rods, with the lower end of the rotating rod rotatably connected to the electric heating plate.

[0012] To facilitate the protection of the charging cable and charging gun, a protective shell is fixedly connected to the charging pile housing near the charging gun. The charging cable and charging gun are both located inside the protective shell. A sealing plate is rotatably connected to the opening of the protective shell via a rotating shaft. An iron block is embedded in the side of the sealing plate away from the rotating shaft. An electromagnet that works in conjunction with the iron block is embedded in the opening of the protective shell.

[0013] To further enhance the impact resistance of the charging pile, the charging pile housing, protective shell, and sealing plate are all made of high-strength alloy steel plates.

[0014] To further improve the stability of the charging pile housing within the groove, multiple drive gears, toothed plates, and limiting rods are equidistantly arranged. After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: Compared with the prior art, which uses ground bolts to fix charging piles, resulting in exposed fixing components and a single anti-theft method, the present invention uses a unique fixing design that replaces the traditional ground bolt fixing structure with a limiting plug and a limiting slot. This concealed and stable connection method makes it difficult for criminals to find and damage the fixing components, greatly increasing the difficulty of disassembly, effectively preventing theft of charging piles, ensuring equipment safety, reducing economic losses, and improving the safety and reliability of charging pile use.

[0015] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention. Example

[0019] Reference Figures 1-6A safe and anti-theft charging pile for new energy vehicles includes a charging pile housing 2, an equipment cavity 201 inside the charging pile housing 2, a charging device 205 installed inside the equipment cavity 201, a charging gun 207 electrically connected to the charging device 205 via a charging cable 206, the charging gun 207 being inserted into the charging pile housing 2, a roof 2013 fixedly connected to the upper end of the charging pile housing 2 via a support rod, the charging pile housing 2 resting in a groove 101 opened in a concrete layer 1, a limiting cavity 202 opened below the equipment cavity 201 inside the charging pile housing 2, and further includes: a rotating shaft 3 rotatably connected in the limiting cavity 202; and a motor 301 fixedly connected to the outside of the charging pile housing 2. The output end of the motor 301 is fixedly connected to the end of the rotating shaft 3 adjacent to the wall near the limiting cavity 202; the support rod 303 is symmetrically fixedly connected in the limiting cavity 202 and located on both sides of the rotating shaft 3; the drive gear 302 is fixedly connected to the rotating shaft 3; the toothed plate 305 is slidably connected to the support rod 303 through the T-shaped slider 304, the toothed plates 305 on the two support rods 303 are symmetrically distributed and both mesh with the drive gear 302; the limiting insert rod 306 is fixedly connected to the end of the toothed plate 305, and the end of the limiting insert rod 306 away from the toothed plate 305 extends out of the limiting cavity 202, and the groove wall of the groove 101 is provided with a limiting slot for use with the limiting insert rod 306.

[0020] Before installation, a groove 101 needs to be pre-cut in the concrete layer 1. The size of the groove 101 is adapted to the charging pile housing 2 so that the charging pile housing 2 can sit stably in it. At the same time, a limiting slot is set on the groove wall of the groove 101 to cooperate with the limiting plug 306, in preparation for subsequent fixed connection.

[0021] When a fixed charging pile needs to be installed, the motor 301 is started. The motor 301 is fixed to the outer wall of the charging pile housing 2 near the limiting cavity 202. Its output end is fixedly connected to the end adjacent to the rotating shaft 3. After the motor 301 is powered on, the output shaft starts to rotate, thereby driving the rotating shaft 3 to rotate in the limiting cavity 202. A drive gear 302 is fixedly connected to the rotating shaft 3. As the rotating shaft 3 rotates, the drive gear 302 also rotates synchronously. The rotation of the drive gear 302 is the core link of power transmission in the entire fixing process. It converts the power of the motor 301 into the driving force that drives the toothed plate 305 to move. When the drive gear 302 rotates, due to the meshing relationship between the toothed plate 305 and the drive gear 302, the toothed plate 305 will move linearly along the guide of the T-shaped slider 304 on the support rod 303. As the drive gear 302 continues to rotate, the toothed plates 305 on both sides will move relative to each other, that is, move towards the groove 101. When the toothed plate 305 moves towards the groove 101, the limiting rod 306 also moves accordingly. Finally, the end of the limiting rod 306 away from the toothed plate 305 will extend out of the limiting cavity 202 and be precisely inserted into the limiting slot pre-opened on the groove wall of the groove 101.

[0022] In this way, a stable connection is formed between the charging pile housing 2 and the concrete layer 1, so that the charging pile is firmly fixed to the ground. This fixing method is different from the traditional ground bolt fixing. Its fixing components are hidden inside the charging pile housing 2 and the concrete layer 1, making it difficult for criminals to find and damage it, thus achieving a good anti-theft effect.

[0023] When the charging pile needs to be disassembled, the motor 301 reverses, causing the rotating shaft 3 to rotate in the opposite direction. The drive gear 302 also rotates in the opposite direction, causing the toothed plate 305 to drive the limit rod 306 out of the limit slot, thereby releasing the fixed connection between the charging pile and the ground, facilitating subsequent handling or maintenance operations.

[0024] Compared to existing technologies where charging piles are mostly fixed with bolts, leaving the fixing components exposed and using only simple anti-theft measures (often just cameras), this charging pile uses a unique design that replaces the traditional bolt fixing structure with a limiting plug 306 that works in conjunction with a limiting slot. This concealed and stable connection method makes it difficult for criminals to find and damage the fixing components, greatly increasing the difficulty of disassembly, effectively preventing theft of the charging pile, ensuring equipment safety, reducing economic losses, and improving the safety and reliability of the charging pile. Example

[0025] Reference Figures 1-6This invention relates to a safe and anti-theft charging pile for new energy vehicles, which is basically the same as that in Embodiment 1. However, an air supply airbag 102 is fixedly connected inside the limiting slot, and a sealing airbag ring 103 is fixedly connected to the opening of the groove 101. The air supply airbag 102 and the sealing airbag ring 103 are connected by a connecting air pipe. When the limiting rod 306 is inserted into the limiting slot, it compresses the air supply airbag 102, causing the gas inside to flow into the sealing airbag ring 103 through the connecting air pipe. After the sealing airbag ring 103 inflates, it tightly fits the charging pile housing 2 and the opening of the groove 101, effectively filling the gap between them. This prevents rainwater, dust, and other impurities from entering, avoiding damage to internal equipment due to moisture and dust accumulation, and extending the service life of the charging pile. The good seal prevents criminals from observing the internal structure through the gaps or using tools to insert into the gaps to damage the fixed components. The sealing barrier formed by the sealing airbag ring 103 increases the difficulty of illegal disassembly, further ensuring the safety of the charging pile.

[0026] A pressure sensor 104 is fixedly connected inside the sealing airbag ring 103. When the limiting rod 306 is inserted into the limiting slot, the air supply airbag 102 is compressed, transmitting gas to the sealing airbag ring 103, causing it to expand. The internal air pressure changes accordingly. The pressure sensor 104 can accurately capture the air pressure value inside the sealing airbag ring 103 in real time and convert it into an electrical signal, which is then transmitted to the charging pile's control system. If the air pressure value reaches the preset normal range, it indicates that the limiting rod 306 has been successfully inserted and squeezed the air supply airbag 102, achieving a stable connection. If the air pressure value does not reach the standard, it means that the limiting rod 306 has not been inserted. Once fully inserted, the system can promptly issue an alarm to remind staff to inspect and adjust, ensuring the accuracy and safety of the charging pile installation. Furthermore, during daily use, the air pressure sensor 104 continuously monitors the air pressure within the sealing airbag ring 103. If an abnormal drop in air pressure occurs, it may be due to a loose limit rod 306, a damaged air supply airbag 102, or a leaking connecting air pipe. The system can promptly detect and issue a warning, prompting staff to inspect the charging pile to prevent safety hazards caused by structural failure, such as the charging pile tipping over, thus ensuring the safe and stable charging process for new energy vehicles.

[0027] Two sets of rollers 2012 are symmetrically installed on the bottom of the charging pile housing 2. The rollers 2012 roll in the groove 101. Compared with the traditional method of placing the charging pile housing 2 directly on the ground, the presence of the rollers 2012 converts sliding friction into rolling friction, which greatly reduces the resistance during movement. When the staff adjusts the position of the charging pile, they do not need to spend a lot of manpower. Only a small external force is needed to push the charging pile housing 2 to slide in the groove 101, which effectively improves the convenience of installation and debugging, and is especially suitable for fine-tuning of the position of large charging piles. Example

[0028] Reference Figures 1-6 A safe and anti-theft charging pile for new energy vehicles is basically the same as in Embodiment 2, but further, an air chamber 204 is provided above the equipment cavity 201 inside the charging pile housing 2, and a blower 4 is installed in the air chamber 204. Storage cavities 203 are symmetrically arranged on both sides of the air chamber 204 inside the charging pile housing 2, and the storage cavities 203 store smoke oil. An electric heating plate 401 is fixedly installed at the lower end of the interior of the storage cavities 203. A liquid filling port connected to the storage cavities 203 is provided on the charging pile housing 2, and a one-way valve is installed in the liquid filling port. The air chamber 204 and the storage cavities 203 are connected through a port. Multiple exhaust ports connected to the air chambers 204 are equidistantly opened at the upper end of the charging pile housing 2, and electromagnetic valves 402 are installed at the exhaust ports, utilizing a pressure sensor 104. The system monitors the air pressure changes within the sealing airbag ring 103 in real time. When malicious actors violently damage the charging pile, causing the casing to vibrate and shake, the air pressure value will fluctuate frequently. The system can accurately identify such abnormal changes. Once the main controller determines that it is a malicious act of sabotage, it will immediately activate the electric heating plate 401 and the blower 4. The electric heating plate 401 quickly heats the smoke oil in the storage chamber 203, causing it to rapidly vaporize and generate a large amount of smoke. The blower 4 then quickly blows the smoke out of the air chamber 204 and out of the exhaust port, simulating a realistic scene of the charging pile catching fire. This visually striking effect can strongly deter malicious actors, making them mistakenly believe that the charging pile has malfunctioned or caught fire, thus prompting them to actively stop their destructive behavior and flee the scene, effectively protecting the charging pile equipment from further damage.

[0029] The upper end of the charging pile housing 2 is provided with an air outlet pipe 403, and the lower end of the air outlet pipe 403 has an air inlet that communicates with the exhaust port. A drive rod 404 is vertically rotatably connected to the upper end of the charging pile housing 2 near the storage cavity 203. Multiple drive blades 405 are fixedly connected at equal intervals around one side of the drive rod 404 extending upwards into the air outlet pipe 403. A rotating rod 406 is fixedly connected to the end of the drive rod 404 extending downwards into the storage cavity 203. Multiple rows of stirring rods 407 are fixedly connected at equal intervals at the position of the rotating rod 406 in the smoke oil. When the blower 4 is working, the blown smoke enters the air outlet pipe 403 through the exhaust port. The high-speed flowing smoke impacts the drive blades 405, causing the drive rod 404 to rotate. The rotating rod 406 extending downwards into the storage cavity 203 also rotates accordingly. The stirring rod 407 agitates the smoke oil. During rotation, it stirs the smoke oil in the storage chamber 203, breaking up the temperature stratification caused by uneven heating. This allows the smoke oil to fully and evenly absorb heat under the action of the electric heating plate 401, avoiding local overheating or underheating, greatly improving the vaporization efficiency of the smoke oil, ensuring sufficient and stable smoke production in a short time, and enhancing the realism of the simulated fire scene. The continuous stirring of the stirring rod 407 can effectively prevent the pigments, special additives and other components added to the smoke oil from settling or stratifying, maintaining the uniformity of the smoke oil components. Whether simulating smoke of different colors or using additives to improve smoke characteristics, it can ensure that the smoke oil is always in the best state, guaranteeing the effect of smoke simulation and improving the reliability of charging pile safety protection.

[0030] Both the rotating rod 406 and the stirring rod 407 are heat-conducting rods. The lower end of the rotating rod 406 is rotatably connected to the electric heating plate 401. The heat-conducting rod material can directly and quickly transfer the heat generated by the electric heating plate 401 to various areas in the storage chamber 203. Compared with ordinary materials, the heat can be quickly diffused to different parts of the e-liquid through the rotating rod 406 and the stirring rod 407, so that the e-liquid can obtain heat from multiple parts in addition to being heated from the bottom of the electric heating plate 401, forming a multi-directional heating effect, which greatly shortens the time for the e-liquid to heat up to the vaporization temperature, thereby generating smoke faster. Example

[0031] Reference Figures 1-6This invention relates to a safe and anti-theft charging pile for new energy vehicles, which is basically the same as embodiment 3, but with a further improvement. A protective shell 208 is fixedly connected to the charging pile housing 2 near the charging gun 207. The charging cable 206 and the charging gun 207 are both located inside the protective shell 208. A sealing plate 209 is rotatably connected to the opening of the protective shell 208 via a pivot. An iron block 2011 is embedded in the side of the sealing plate 209 away from the pivot. An electromagnet 2010, which works in conjunction with the iron block 2011, is embedded in the opening of the protective shell 208. The protective shell 208 completely encloses the charging cable 206 and the charging gun 207, providing them with a physical protective barrier. This effectively prevents the equipment from being subjected to external impacts or scratches, and prevents sharp objects from scratching or damaging the outer sheath of the charging cable 206. The charging gun 208 interface is designed to withstand dust, rain, and other environmental factors, reducing equipment failures caused by external factors, extending the service life of the charging cable 206 and charging gun 207, and ensuring the normal use of the charging pile. The sealing plate 209 is rotatably connected to the protective shell 208 via a pivot, and the iron block 2011 on the sealing plate 209 can be tightly attracted to the electromagnet 2010 at the opening of the protective shell 208. When the charging pile is not in use, the electromagnet 2010 is energized and generates magnetism, firmly attracting the iron block 2011 and fixing the sealing plate 209, so that the protective shell 208 forms a closed space, preventing criminals from stealing or damaging the charging cable 206 and charging gun 207. This design increases the difficulty of theft and effectively protects the safety of the key components of the charging pile.

[0032] The charging pile housing 2, protective shell 208, and sealing plate 209 are all made of high-strength alloy steel plate. The high strength of the alloy steel plate greatly increases the difficulty for criminals to damage and dismantle it. Traditional tools cannot easily cut or pry open the structure made of high-strength alloy steel plate. Combined with the internal anti-theft device, it can form a solid physical barrier, effectively preventing theft, reducing the risk of charging pile theft, and protecting the safety of equipment and property. Example

[0033] Reference Figures 1-6 A safe and anti-theft charging pile for new energy vehicles is basically the same as that in Example 4, but further, multiple drive gears 302, tooth plates 305 and limit rods 306 are equidistantly arranged.

[0034] Multiple equally spaced drive gears 302, toothed plates 305, and limiting rods 306 can form a multi-point fixing structure when the charging pile is connected to the ground. Compared with a single or a few fixing components, multi-point fixing can evenly distribute the external force on the charging pile, avoiding excessive local stress that could lead to loosening of the connection. Even if the charging pile is subjected to external force impacts from different directions (such as vehicle collisions or impacts from criminals), the multiple limiting rods 306 can work together to firmly fix the charging pile in the groove 101, greatly improving the overall stability and reliability of the fixing.

[0035] The presence of multiple limiting rods 306 increases the difficulty for criminals to dismantle the charging pile. To remove the charging pile, multiple limiting rods 306 and their connecting structures must be destroyed simultaneously. The equidistant distribution design disperses the points of destruction, increasing the time cost and technical difficulty of theft. In addition, the multi-point fixing structure makes it difficult for criminals to pry the charging pile out of the groove 101, further improving the anti-theft performance of the charging pile and providing a more solid guarantee for equipment security.

[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention.
