Description

Technical Field

[0001] This invention relates to the field of anti-theft devices for charging piles, specifically an anti-theft electric vehicle charging pile structure. Background Technology

[0002] Electric bicycles are a major mode of transportation for short-distance travel, boasting a huge market and extremely high usage frequency. To meet charging needs, charging stations are widely deployed in residential and commercial areas. However, with the significant increase in the number of charging stations, theft has become increasingly prominent. Some criminals target valuable components within the charging stations, dismantling and selling them, causing serious losses to operators, users, and public facility management.

[0003] Common theft methods typically involve the following steps: First, thieves cut off the main power supply to the charging station, causing it to lose power completely; then, they disconnect the wiring between the charging station and each charging socket; finally, they remove the charging station entirely from its installation location. Because the internal alarm or monitoring components of the charging station often malfunction after a power outage, they cannot provide timely warnings when theft occurs, resulting in weak anti-theft capabilities.

[0004] Furthermore, the existing charging piles are installed and fixed in a relatively simple way, usually using side bolts for fastening or a back-mounted installation similar to a household television, fixing them to a wall, column, or other structure. While this type of installation is convenient for construction and maintenance, it also means that dismantling is relatively easy, objectively reducing the difficulty of theft and indirectly condoning theft. Summary of the Invention

[0005] The purpose of this invention is to provide an anti-theft electric vehicle charging pile structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an anti-theft electric vehicle charging pile structure, comprising a charging pile and an anti-theft structure; The anti-theft structure includes a mounting base structure installed in a fixed facility and a movable snap-fit ​​structure connected to the mounting base structure. The mounting base structure and the movable snap-fit ​​structure are connected by a connecting shaft, which is also connected to the charging pile for fixing the charging pile to the mounting base structure. The mounting base structure includes a wedge-shaped fastener and a connecting seat. One end of the wedge-shaped fastener is fixedly connected to the fixing facility. The connecting seat is fixedly connected to the wedge-shaped fastener by squeezing to force the wedge-shaped fastener to expand. The movable snap-fit ​​structure includes a spiral groove cone and a floating rod mechanism. The end of the spiral groove cone is connected to the output shaft of the electric push rod, and the floating rod mechanism is connected to the guide rod by floating up and down. The guide rod is fixedly connected inside the charging pile. The end of the connecting shaft is provided with an annular electromagnet, which is electrically connected to each set of charging lines of the charging pile in a disconnectable manner. The charging station is equipped with an observation component, which is connected to a temporary power source.

[0007] Preferably, the observation component includes a radar and a camera, and the observation component is electrically connected to the electric actuator.

[0008] Preferably, the connecting seat has a tapered rod inside, which compresses the wedge-shaped fastener to lock the connecting seat in place.

[0009] Preferably, the outer side wall of the spiral groove cone is provided with a plurality of spiral grooves of constant depth, the spiral grooves penetrate the side wall of the spiral groove cone, and the tail section of the spiral groove is provided with a positioning groove.

[0010] Preferably, the spiral groove cone is connected to the connecting seat via a damping ring.

[0011] Preferably, the floating rod mechanism includes a sliding rod, a clamping plate, and a floating rod. The sliding rod is provided with a corresponding spiral groove, the clamping plate is disposed on the sliding rod and holds a conductive sheet in the clamping plate, and the floating rod is disposed above the clamping plate.

[0012] Preferably, the bottom of the sliding rod is provided with a ball, which is positioned by cooperating with the positioning groove. The diameter of the sliding rod is adapted to the width of the spiral groove. The lower end of the sliding rod is provided with a hook facing the rear end of the spiral groove cone. When the hook is located at the end of the spiral groove cone, it can hook the spiral groove cone.

[0013] Preferably, the conductive sheet is electrically connected to the charging circuit of the socket.

[0014] Preferably, a reset elastic element is provided between the floating rod and the guide rod.

[0015] Preferably, the socket is equipped with an independent temporary power supply.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through the cooperation of the mounting base structure and the movable snap-fit ​​structure, will actively activate the electric push rod to make the snap hook catch the spiral groove cone after the observation component detects someone approaching the charging pile. On the one hand, it connects the internal circuit of the charging pile with the mounting base structure, which can damage more parts and reduce theft when subjected to violent disassembly. On the other hand, violent disassembly and damage to the charging circuit of the socket will also trigger the temporary power supply of the socket, and realize alarm or feedback information through the alarm structure of the socket itself. 2. This invention achieves a fixed connection between the charging pile installed on the mounting base structure and the fixed facility by embedding the mounting base structure, which is no longer installed by simple side bolts, thus increasing the cost of theft; 3. In this invention, the hook that holds the spiral groove cone will automatically open and retract the spiral groove cone after any charging socket is activated, and will no longer hook it. At the same time, the charging pile after being powered on can also correctly activate its own anti-theft or monitoring components and send out an alarm signal in time when theft occurs.

Detailed Implementation

[0019] The technical solutions of 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.

[0020] Please see Figures 1 to 9The present invention provides a technical solution: an anti-theft electric vehicle charging pile structure, which mainly includes a charging pile 1 and an anti-theft structure integrated in the charging pile 1 and fixed facilities, such as walls and columns.

[0021] The anti-theft structure includes a mounting base structure 2 and a movable snap-fit ​​structure 3. The mounting base structure 2 is used for pre-embedding or high-strength fixing inside fixed facilities such as walls, and is the foundation of the anti-theft system.

[0022] The movable locking structure 3 is installed inside the charging pile 1 and is controllably connected to the mounting base structure 2 via a high-strength connecting shaft 4. This connecting shaft 4 not only connects the mounting base structure 2 and the movable locking structure 3, but is also fixedly connected to the shell or internal frame of the charging pile 1. When the connecting shaft 4 is locked to the mounting base structure 2, the entire charging pile 1 is securely fixed to the fixture and cannot be disassembled from the outside using simple bolts. Furthermore, a connecting structure can be installed on the movable locking structure 3, and a connecting plate can be installed inside the charging pile 1. Connecting the connecting plate to the connecting structure creates a more robust connection. In the event of violent theft, this connection will cause greater damage, increasing the cost of theft and reducing the potential profits.

[0023] The mounting base structure 2 includes a wedge-shaped fastener 21 and a connecting base 22. The wedge-shaped fastener 21 is an expansion-type metal claw with an opening, one end of which is pre-fixed to the concrete or steel structure of the building by welding or expansion bolts.

[0024] The connecting seat 22 is a hollow component with a conical surface at its center. When the connecting seat 22 is pressed into the wedge-shaped fastener 21 by an external force, the conical surface of the connecting seat 22 will force the open end of the wedge-shaped fastener 21 to expand radially outward, thereby tightly locking it into the mounting hole of the fixing device.

[0025] The movable locking structure 3 includes a spiral groove cone 31 and a floating rod mechanism 32. The end of the spiral groove cone 31 is connected to the output shaft of a small but powerful electric actuator 33, which is fixed to the internal support of the charging pile 1. The floating rod mechanism 32 is not rigidly fixed, but is slidably connected to the guide rod 5. The two ends of the guide rod 5 are fixed to the inner wall of the charging pile 1, providing a precise vertical movement trajectory for the floating rod mechanism 32. The electric actuator 33 is connected to the observation structure. When the observation structure detects someone approaching, it actively activates the electric actuator 33, locking the movable locking structure 3. This trigger-type structure is mainly used to ensure that the entire structure is in an unlocked state when not being penalized, facilitating the maintenance and repair of the charging pile.

[0026] A ring-shaped electromagnet 6 is located at one end of the connecting shaft 4 near the movable latching structure 3. This ring-shaped electromagnet 6 is electrically connected to each set of charging lines in a disconnectable manner to the charging pile 1; the charging lines are the wiring harnesses leading from the main circuit board of the charging pile to each charging socket. During normal operation, the charging lines are not powered by the ring-shaped electromagnet 6, resulting in no magnetic force, and the latch 326 can engage with the spiral groove cone 31. Once the charging lines are powered, the ring-shaped electromagnet 6 becomes magnetic, attracting the latch 326 to expand, releasing the spiral groove cone 31, and locking into contact.

[0027] In addition, the charging station 1 is equipped with an observation component on its casing, which has an independent temporary power source, such as a built-in rechargeable lithium battery. Even if the main power supply to the charging station is cut off by thieves, the observation component can still continue to operate using the temporary power source to monitor the surrounding environment.

[0028] In this embodiment, the observation component includes at least one radar sensor and a high-definition camera. The radar is used to continuously detect whether there are moving objects, especially people, within a certain range around the charging pile. The camera is used to collect image information, and the two work together to detect whether someone is approaching the charging pile 1. The signal output terminal of the observation component is electrically connected to the control terminal of the electric actuator 33. When a person is detected to be continuously approaching, the observation component sends a trigger signal to the electric actuator 33, causing it to move the spiral groove cone 31 outward.

[0029] In this embodiment, to achieve reliable locking between the wedge fastener 21 and the connecting seat 22, a tapered rod 221 is fixedly installed at the center of the connecting seat 22. The diameter of the tapered rod 221 gradually decreases from its root to its tip. During installation, when the connecting seat 22 is pulled into the wedge fastener 21, the tapered rod 221 will first insert into the center of the opening of the wedge fastener 21, and as the compressive force increases, it will evenly expand each claw of the wedge fastener 21 from the inside out, generating a huge positive pressure with the inner wall of the fixing device, thereby achieving extremely reliable friction locking.

[0030] In this embodiment, to achieve precise motion control of the movable locking structure 3, multiple spiral grooves, such as 10, are evenly formed on the outer circumferential sidewall of the spiral groove cone 31. These spiral grooves have a constant depth and are through grooves penetrating the sidewall of the spiral groove cone 31. At the end of each spiral groove, near the electric actuator 33, an inwardly recessed positioning groove 311 is provided. The positioning groove 311 provides a stable locking point when the floating rod mechanism 32 reaches its endpoint, preventing accidental disengagement due to vibration or other reasons.

[0031] In this embodiment, to ensure that the helical groove cone 31 maintains a stable posture and does not wobble excessively during operation, a damping ring is provided between the outer wall of the helical groove cone 31 and the inner wall of the connecting seat 22. This damping ring can be a wear-resistant ring made of polytetrafluoroethylene or an O-ring. The damping ring provides appropriate rotational and axial motion damping, allowing the helical groove cone 31 to smoothly extend and retract under the drive of the electric actuator 33 and without external force, until the sliding rod 321 contacts the helical groove and forces it to rotate under the contact force.

[0032] In this embodiment, the floating rod mechanism 32 includes a sliding rod 321, a clamping piece 322, and a floating rod 323. The number of sliding rods 321 is the same as the number of spiral grooves on the spiral groove cone 31, and each sliding rod 321 is embedded in a corresponding spiral groove. A pair of clamping pieces 322 are fixed to the upper middle part of each sliding rod 321, and a conductive piece 324 is clamped and fixed between the pair of clamping pieces 322. The floating rod 323 is located above all the clamping pieces 322 and contacts or connects to the top of all the sliding rods 321. When the sliding rod 321 rises along the spiral groove, it will push up the floating rod 323. When a user needs to use the charging pile, the conductive piece 324 is powered on for payment. The charging line is connected to the conductive piece 324. Through the connection of the line, if someone wants to unlock the mounting base structure 2 and the movable latching structure 3 by paying for charging and carry out violent theft, it will cause more damage to the components and reduce the theft proceeds.

[0033] In this embodiment, a freely rolling ball is mounted at the bottom of each sliding rod 321. This ball matches the shape of the positioning groove 311 within the spiral groove. When the sliding rod 321 reaches the end of the spiral groove, the ball falls into the positioning groove 311, providing a clear tactile feedback and assisting in positioning. A small clearance fit is used between the diameter of the sliding rod 321 and the width of the spiral groove to ensure smooth sliding without significant wobble.

[0034] Each sliding rod 321 has a reverse hook 322 at its lower end. The hook tip of the hook 322 faces the rear end of the spiral groove cone 31, i.e., the end where the electric push rod 33 is located. When the electric push rod 33 pushes the spiral groove cone 31 to extend, and the sliding rod 321 moves relative to the spiral groove to its end, the hook 322 will pass over the end face of the spiral groove cone 31 and, under the action of elasticity, accurately hook onto the end edge of the spiral groove cone 31. At this time, the mechanical interlock between the hook 322 and the spiral groove cone 31 can also maintain the connection relationship, so that the charging pile 1 cannot be easily pulled out.

[0035] In this embodiment, each conductive sheet 324 is electrically connected to the charging circuit of the corresponding socket 200 via a flexible wire. This directly associates the charging circuit with the mechanical locking state.

[0036] In this embodiment, to achieve automatic reset of the floating rod mechanism 32, a reset elastic element, such as a helical spring, is provided between the top or bottom of the floating rod 323 and the guide rod 5. When the electric actuator 33 drives the helical groove cone 31 to retract, the hook 322 disengages from the helical groove cone 31, and the sliding rod 321 slides in the opposite direction along the helical groove under the action of the reset elastic element, driving the floating rod 323 and the conductive plate 324 back to the initial disconnected position, preparing for the next locking cycle.

[0037] In this embodiment, each individual socket 200 has a built-in independent temporary power supply. This temporary power supply is connected to the alarm circuit of the socket 200, such as a buzzer and a wireless communication module. When the main power supply of the charging pile is cut off, if a thief forcibly damages the charging line, attempts to remove the socket from the outside, or cuts the wires, the power failure detection circuit inside the socket will be triggered. At this time, the temporary power supply will immediately power the alarm circuit, emitting a piercing local alarm sound, and sending a theft alarm signal to the management platform via the wireless network, thus enabling the alarm function to continue even when completely disconnected from the main body of the charging pile.

[0038] Working principle: 1. Initial standby state When no one approaches the charging station 1 and no user pays for its use, the charging station 1 is in standby mode: The observation component is powered by the main power supply and continuously monitors the surrounding environment, but does not trigger the electric actuator 33 to move. The electric actuator 33 is in the retracted state, and the spiral groove cone 31 is retracted inside the charging pile 1, without locking with the floating rod mechanism 32.

[0039] The annular electromagnet 6 is in a de-energized state, but at this time, because the spiral groove cone 31 is not extended, the hook 322 does not hook the spiral groove cone 31.

[0040] The entire charging pile 1 is connected to the fixed facility only through the mounting base structure 2, but the movable locking structure 3 is in the unlocked state, which facilitates normal disassembly by maintenance personnel.

[0041] 2. Someone has been detected approaching. When the observation component detects someone continuously approaching the charging station: the observation component sends a trigger signal to the electric push rod 33; The electric actuator 33 is activated, pushing the spiral groove cone 31 to extend outward; As the spiral groove cone 31 extends, it will gradually rotate due to the cooperation between the spiral groove on its outer wall and the sliding rod 321, as well as the damping effect of the damping ring. The ball at the bottom of each sliding rod 321 rolls along the spiral groove, causing the sliding rod 321 to move towards the end of the spiral groove. When the sliding rod 321 reaches the end of the spiral groove, the ball falls into the positioning groove 311 to achieve positioning; at the same time, the hook 322 at the lower end of the sliding rod 321 passes over the end face of the spiral groove cone 31 and hooks the end edge of the spiral groove cone 31 in the opposite direction under the action of elastic force.

[0042] At this time, the movable locking structure 3 and the mounting base structure 2 are mechanically interlocked through the hook 322 and the spiral groove cone 31, preventing the charging pile 1 from being pulled out. During this stage, the charging circuit is not yet energized, and the annular electromagnet 6 has no magnetic force, thus not interfering with the locking state of the hook.

[0043] 3. Users pay for charging normally. Once a legitimate user needs to charge their phone and completes the payment: The main circuit board of the charging pile controls the charging circuit to supply power to the corresponding socket 200.

[0044] The electrical energy of the charging line is simultaneously transmitted to the annular electromagnet 6 at the end of the connecting shaft 4. The annular electromagnet 6 is energized and generates magnetic force, which attracts the hook 322 on the sliding rod 321 to expand outward, causing the hook 322 to disengage from the end of the spiral groove cone 31. The mechanical lock is released, and the charging pile 1 returns to its detachable state.

[0045] At the same time, the charging circuit also supplies power to the socket 200 through the conductive sheet 324 and other paths, so the user can charge normally.

[0046] 4. Personnel leave When the user moves away from the charging station, the observation component detects the absence signal, and the electric push rod 33 retracts the spiral groove cone 31 in the reverse direction. After the hook 322 disengages from the spiral groove cone 31, under the action of the reset elastic element, the sliding rod 321 slides in the reverse direction along the spiral groove, driving the floating rod 323 and the conductive sheet 324 back to their initial positions. The entire movable latching structure 3 returns to the unlocked standby state, facilitating subsequent maintenance.

[0047] 5. Anti-theft response in theft scenarios When thieves attempt to steal a charging station, the typical steps are: 1. Disconnect the main power supply; 2. Cut the charging cables; 3. Forcibly remove it. This structure provides the following method to address this process: After the main power is cut off: the observation component can continue to work due to its own temporary power supply, continue to monitor and trigger the locking action; when the annular electromagnet 6 loses power, the observation component will trigger the electric push rod 33.

[0048] Attempts to cut charging lines or forcibly remove sockets: Each individual socket 200 has its own independent temporary power supply and alarm circuit. When the wiring is damaged, the power failure detection circuit is triggered, the temporary power supply is immediately activated, the buzzer sounds a piercing alarm, and a theft alarm signal is sent to the management platform via the wireless communication module.

[0049] Forcibly removing the charging station: Because the hook 322 and the spiral groove cone 31 are mechanically interlocked, and the wedge-shaped fastener 21 of the mounting base structure 2 will tighten under tension, the charging station cannot be pulled out. If the thief forcibly damages it, it will cause irreversible tensile damage to multiple internal components, thereby reducing the theft profit and increasing the theft cost.

[0050] 6. Maintenance Status When authorized maintenance personnel need to perform normal maintenance: they can temporarily disable the triggering function of the observation component using a special tool or background command, or manually control the electric push rod 33 to remain in the retracted state. At this time, the active locking structure 3 will not lock, and maintenance personnel can normally disassemble the charging pile for inspection.

[0051] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or its equivalents are included in this invention.
