Abstract
Description
Technical Field
[0001] This utility model belongs to the field of new energy vehicle charging technology, specifically relating to a precise insertion structure for a new energy charging gun. Background Technology
[0002] Traditional fixed charging stations are gradually being replaced by more advanced and flexible overhead rail charging systems due to their inherent drawbacks. In practical applications, the limitations of fixed charging stations are becoming increasingly apparent. Not only are their installation locations fixed, making it difficult to flexibly meet the charging needs of new energy vehicles in different parking layouts, but their high material costs and subsequent maintenance expenses also place a heavy burden on operators.
[0003] The applicant proposes improvements to application number 2024232326691, entitled "Magnetic Contact Power-On Device for New Energy Vehicle Charging Boxes." While existing magnetic contact power-on charging boxes innovate the electrical connection method, their electromagnetic coupling design has inherent flaws. The pulsed mechanical stress generated during magnetic docking directly acts on the screw fastening points. Under frequent cyclic forces, the screw preload decreases significantly, leading to loosening of the connection and requiring regular screw tightening maintenance. More critically, the instantaneous electric arc generated by positioning deviation during magnetic docking can cause erosion of the contact surface due to high temperatures, accelerating electrode material wear. Long-term operation not only increases contact resistance and causes localized overheating but also poses a significant safety hazard of fire caused by electrical sparks, severely restricting the reliability and safety of the charging equipment. Utility Model Content
[0004] The purpose of this utility model is to provide a precise insertion structure for a new energy charging gun, in order to solve the technical problems mentioned in the background art, such as the electromagnetic coupling design defects in the magnetic contact charging box, the pulse mechanical stress generated by the magnetic connection causing the screw preload to decrease, the connection to loosen, requiring regular maintenance, and the instantaneous arc caused by positioning deviation melting the contact surface and accelerating wear, posing a fire safety hazard and affecting the reliability and safety of the equipment.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a precise insertion structure for a new energy charging gun, comprising a slide rail, a track-walking motor, a hanging box, a hoisting charging box, an electronic connector, a power receiving female connector, and a column. The track-walking motor is mounted on the slide rail, and the hanging box is fixedly installed below the track-walking motor. An electric ball screw motor is mounted on the hanging box, and the hoisting charging box is slidably installed in the hanging box. The electric ball screw motor drives the hoisting charging box to move forward and backward. Application number: 202520595070X, entitled "Suspended Mobile New Energy Vehicle Charging Device," mentions this transmission and docking process.
[0006] Both ends of the electronic base are installed in the hoisting charging box through adjustment components. A sliding receiving box is also provided on the column, and the power receiving female base is fixedly installed in the sliding receiving box.
[0007] Preferably, the adjustment assembly includes a set of sliding blocks, two sets of springs, and a set of sliding rods. The two sliding rods are arranged horizontally and parallel inside the suspended charging box. The sliding blocks are slidably mounted on the sliding rods. Springs are provided at both ends of the sliding blocks, and an electronic connector is provided between the sliding blocks.
[0008] Preferably, the electronic connector includes a frame box with sliding blocks arranged vertically on the frame box. A set of limiting rods is vertically arranged in the frame box, and a floating rocking box and a support spring are slidably arranged on the limiting rods. The support spring is used to support the floating rocking box, and an electronic connector is arranged inside the floating rocking box. Rotating rods are arranged at the upper and lower ends of the electronic connector. Two elliptical holes are provided on the floating rocking box, and the rotating rods pass through the elliptical holes. A rotating support is provided on the elliptical hole at the top of the floating rocking box, and the rotating rods pass through the rotating support. A rocking connector is horizontally arranged on the electronic connector. Hook springs are arranged on both sides of the rocking connector and are connected to the frame box. Deep insertion holes are provided on both sides of the electronic connector.
[0009] Preferably, the power receiving female connector includes a mounting angle iron, a power receiving female head, and pins. The mounting angle iron is provided with a power receiving female head, and the power receiving female head is provided with a set of pins.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] When the electronic connector is plugged into the power receiving female connector, the pins of the power receiving female connector are inserted into the deep hole of the connector. When the electronic connector is misaligned laterally, the adjustment component helps to eliminate the error when the pins of the power receiving female connector are inserted into the deep hole of the connector.
[0012] When vertical misalignment occurs, the floating swing box moves up and down on the limit rod to overcome the misalignment. A support spring lifts the floating swing box. For minor lateral misalignment, the hook springs on both sides of the swing connector engage, causing the frame box to float and swing slightly. Compared to existing technologies, this device significantly improves the success rate of mating between the electronic connector and the power receiving socket through the coordinated operation of a multi-dimensional error compensation mechanism. By eliminating mechanical impact and misalignment sparks at the moment of contact, it significantly extends the service life of electrical connection components and effectively avoids safety hazards caused by electrical sparks.
