A charging pile equipped with a reversing warning mechanism

Abstract

This utility model discloses a charging pile equipped with a reversing warning mechanism, relating to the field of charging pile technology. It includes a charging pile body with two symmetrically distributed wires fixedly connected to its bottom. Each wire is fixedly connected to two detection structures; the detection structures are aligned with the vehicle's tires. This charging pile with a reversing warning mechanism achieves contact-based immediate warning by mechanically linking a rotating plate driven by tire pressure to a linkage and a moving plate, triggering the on / off control of fixed and elastic electrodes. It also dynamically monitors the distance between the rear of the vehicle and the charging pile body using a non-contact distance detector, forming a dual protection system that combines mechanical and electronic components. The two systems operate independently yet collaboratively, responding to physical actions involving direct tire contact and providing proactive warnings for complex scenarios such as excessive vehicle length or parking deviation, significantly improving protection coverage and reliability.

Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, specifically a charging pile equipped with a reversing warning and reminder mechanism. Background Technology

[0002] Charging stations are devices specifically designed to provide electrical energy to electric vehicles. They convert electrical energy and transmit it to the electric vehicle's battery to replenish the vehicle's range. Existing charging stations are generally installed next to parking spaces, which makes it easy for drivers to collide with them while driving.

[0003] To overcome the aforementioned deficiencies, a Chinese patent (publication number: CN219505870U) discloses a collision avoidance warning system for new energy vehicle charging piles. This system includes a base plate, a charging pile body fixedly connected to the top of the base plate, a charging gun on the right side of the charging pile body, a canopy fixedly connected to the top of the charging pile body, and a collision avoidance warning component inside the charging pile body. This component includes a housing fixedly connected inside the charging pile body. When a new energy vehicle is reversing and about to collide with the charging pile body, the protective plate moves towards the inside of the housing, and a spring shock absorber buffers the force generated. Simultaneously, the spring also buffers and dampens the force generated by the sliding plate's movement. However, as the sliding plate moves, its copper plate protrusion moves towards the side closer to the copper plate. When the copper plate protrusion contacts the copper plate, a warning light is triggered to alert the driver of a collision, thus protecting the charging pile body.

[0004] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation: charging piles installed next to parking spaces are at risk of collision. Existing charging piles generally achieve collision protection by adding a reinforcing structure to their outside, but they cannot provide early warning of an impending collision with the charging pile, and the early warning range of the charging pile is limited. Utility Model Content

[0005] The purpose of this utility model is to provide a charging pile equipped with a reversing warning mechanism to solve the problems in the above-mentioned background technology that it is impossible to warn of an impending collision with the charging pile, and that the warning range of the charging pile is limited.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a charging pile equipped with a reversing warning and reminder mechanism, comprising a charging pile body, wherein two symmetrically distributed wires are fixedly connected to the bottom of the charging pile body, and each wire is fixedly connected to two detection structures;

[0007] The detection structure is aligned with the vehicle tires, and the detection structure includes a mounting box. A mounting ring is fixedly connected to the top of the mounting box, and a downward rotating plate is hinged to one side of the mounting ring. A moving plate is slidably connected inside the mounting box.

[0008] Preferably, the mounting box is pre-embedded underground, and the mounting ring is flush with the ground. The moving plate and the downward rotating plate are hinged with equally spaced connecting rods.

[0009] Preferably, guide rods are fixedly connected to the four corners of the mounting box, and guide sleeves aligned with the guide rods are provided at the four corners of the moving plate, with the guide rods slidably connected inside the guide sleeves.

[0010] Preferably, a spring is fixedly connected between the bottom of the guide sleeve and the inner bottom of the mounting box, and the spring is sleeved on the outside of the guide rod.

[0011] Preferably, a fixed electrode is fixedly connected to the top center of the mounting box, and an elastic electrode that contacts and aligns with the fixed electrode is fixedly connected to the bottom center of the pressing rotating plate, and both the elastic electrode and the fixed electrode are electrically connected to their respective wires.

[0012] Preferably, cables are fixedly connected to both sides of the charging pile body at equal intervals, and charging guns are electrically connected to the ends of the cables. Two symmetrically distributed storage seats are provided on the front side of the charging pile body, and the charging guns are detachably snapped into the storage seats.

[0013] Preferably, the charging pile body has a speaker, a warning light and a distance detector arranged vertically in the middle of the front side, and the charging pile body has a microcontroller inside, and the microcontroller is electrically connected to the fixed electrode and elastic electrode of the speaker, warning light, distance detector and detection structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This charging pile, equipped with a reversing warning mechanism, uses the mechanical linkage of a rotating plate driven by the tire pressing down to trigger the on / off control of fixed and elastic electrodes, achieving contact-based instant warning. It also uses a non-contact ranging technology of a distance detector to dynamically monitor the distance between the rear of the vehicle and the charging pile body, forming a dual protection system that complements mechanical and electronic technologies. The two systems operate independently and work together, responding to physical actions such as direct tire contact and providing proactive warnings for complex scenarios such as excessive vehicle length or parking deviation, significantly improving the protection coverage and reliability.

[0016] The design of the guide rod, guide sleeve and spring in the detection structure ensures that the moving plate moves smoothly down along a fixed trajectory when under pressure, and is elastically reset by the spring to avoid mechanical jamming or false triggering; the pre-embedded layout of the mounting box and the design of the mounting ring being flush with the ground reduce the interference of the external environment on the detection structure and facilitate later maintenance.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1 - Figure 5This utility model provides the following technical solution: A charging pile equipped with a reversing warning mechanism includes a charging pile body 1. Two symmetrically distributed wires 2 are fixedly connected to the bottom of the charging pile body 1, and each wire 2 is fixedly connected to two detection structures. The detection structures are aligned with the vehicle tires, and each detection structure includes a mounting box 3. A mounting ring 4 is fixedly connected to the top of the mounting box 3, and a downward rotating plate 6 is hinged to one side of the mounting ring 4. A moving plate 5 is slidably connected inside the mounting box 3. The mounting box 3 is pre-buried underground, and the mounting ring 4 is flush with the ground. The moving plate 5 and the downward rotating plate 6 are positioned... The mounting box 3 is hinged with equidistant connecting rods 7; guide rods 8 are fixedly connected to the four corners of the mounting box 3; guide sleeves 9 are provided at the four corners of the moving plate 5, aligned with the guide rods 8, and the guide rods 8 are slidably connected inside the guide sleeves 9; springs 10 are fixedly connected between the bottom of the guide sleeves 9 and the inner bottom of the mounting box 3, and the springs 10 are sleeved on the outside of the guide rods 8; a fixed electrode 11 is fixedly connected to the middle of the top of the mounting box 3; an elastic electrode 12 is fixedly connected to the middle of the bottom of the pressing rotating plate 6, which is aligned with the fixed electrode 11, and both the elastic electrode 12 and the fixed electrode 11 are electrically connected to the corresponding wires 2.

[0026] When the vehicle enters the charging parking space and begins to reverse, the tires gradually approach the detection structure pre-embedded at the bottom of the charging pile body 1. This detection structure is connected to the internal control system of the charging pile by two symmetrically distributed wires 2. Each wire end is equipped with two sets of detection devices. The top of its mounting box 3 is flush with the ground through a mounting ring 4. Inside the mounting box 3 is a moving plate 5, which is slidably connected to the guide rods 8 at the four corners of the mounting box 3 through guide sleeves 9 at the four corners. Springs 10 are sleeved on the outside of the guide rods. When the tire presses down on the downward rotating plate 6, the weight of the wheel forces the downward rotating plate 6 to rotate downward around the hinge point of the mounting ring 4, and pushes the moving plate 5 down along the guide rods 8 through the equidistantly distributed connecting rods 7, while compressing the springs 10 to buffer the impact force.

[0027] As the moving plate 5 continues to move downwards, the elastic electrode 12 fixed at its bottom gradually approaches the fixed electrode 11 at the top of the mounting box 3. When the two electrodes contact, the circuit is activated and an electrical signal is generated. This signal is transmitted through the wire 2 to the microcontroller inside the charging pile body 1. The microcontroller then triggers the speaker 16 and the warning light 17, using a combination of sound and light to warn the driver to stop immediately. If the vehicle leaves the detection structure, the elastic restoring force of the spring 10 will push the moving plate 5 back to its original position, the elastic electrode 12 will separate from the fixed electrode 11, the circuit will be disconnected, and the warning will stop.

[0028] Example 2: Based on Example 1, please refer to... Figure 1 and Figure 6The following structure is also disclosed: Equally spaced cables 13 are fixedly connected to both sides of the charging pile body 1, and charging guns 14 are electrically connected to the ends of the cables 13. Two symmetrically distributed storage seats 15 are provided on the front side of the charging pile body 1, and the charging guns 14 are detachably snapped into the storage seats 15. A speaker 16, a warning light 17, and a distance detector 18 are arranged vertically in the middle of the front side of the charging pile body 1. A microcontroller is provided inside the charging pile body 1, and the microcontroller is electrically connected to the speaker 16, the warning light 17, the distance detector 18, and the fixed electrode 11 and the elastic electrode 12 of the detection structure.

[0029] The ends of the cables 13 on both sides of the charging pile body 1 are connected to the charging gun 14. The charging gun can be locked into the storage seat 15 to prevent the cables from dragging and affecting the detection structure. When the vehicle fails to trigger the detection structure due to its long body or parking position deviation, the distance detector 18 will activate the auxiliary protection function. This detector is located in the middle of the front side of the charging pile body 1 and uses ultrasonic or infrared ranging technology to monitor the distance between the rear of the vehicle and the charging pile in real time.

[0030] If the vehicle does not run over the detection structure but is too close when reversing, the distance detector 18 will feed back the real-time data to the microcontroller. The microcontroller will determine the risk level based on the preset safety threshold: when the distance approaches the critical value, the warning light 17 will switch to a yellow flashing mode; if the vehicle continues to approach, the warning light will turn to a solid red and be accompanied by a high-frequency alarm sound from the speaker 16. The storage base 15 of the charging pile body 1 adopts a magnetic adsorption design to ensure that the charging gun 14 remains stable under vehicle vibration or external impact, and to avoid secondary collisions caused by the equipment falling off.
