Description

Technical Field

[0001] This utility model relates to the field of charging device technology, specifically to a trolley charging device with good protection performance. Background Technology

[0002] With the booming development of the electric vehicle market, charging facilities, as a key infrastructure to ensure the energy supply of electric vehicles, are becoming increasingly important.

[0003] Traditional electric vehicle charging devices have gradually revealed numerous problems in practical use. On the one hand, in terms of structural design, many early pole-mounted charging devices are simple and unstable. The poles are mostly ordinary column-shaped, which are easily deformed and damaged by vehicle collisions or minor daily bumps, affecting their service life and safety. The installation method is also relatively rudimentary, often relying solely on simple bolts to fix it directly to the ground, lacking effective buffering and positioning reinforcement designs. When the ground is uneven or encounters external impacts, it is prone to loosening, tilting, etc., which can lead to unstable charging line connections and even cause dangers such as power outages and short circuits.

[0004] On the other hand, the chaotic management of charging cables has always been a problem. Power cables haphazardly dragged on the ground are not only easily run over and worn by passing vehicles, increasing the risk of cable sheath damage and internal short circuits, but also obstruct traffic in parking lots, posing safety hazards such as pedestrians tripping and vehicles being scratched. Meanwhile, traditional charging guns have shortcomings in their protection. When not in use, the charging gun interface is usually not effectively shielded, allowing dust, debris, and moisture to easily penetrate. Over time, this accumulation corrodes the metal contacts inside the interface, reducing charging efficiency and even causing poor contact, leading to charging interruptions or abnormal overheating, seriously affecting the stability and safety of charging.

[0023] 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.

[0024] Example

[0025] like Figure 1-3 As shown, an embodiment of the present invention provides a trolley charging device with good protection performance, including a column 1;

[0026] The support column 1 is a flat U-shape made of stainless steel. The flat U-shape design ensures strength while providing greater impact resistance compared to ordinary column shapes, making it less prone to deformation from vehicle collisions or everyday bumps. The stainless steel material offers excellent corrosion resistance, extending the device's lifespan. The mounting plate 2 is fixed to the bottom of the support column 1, with mounting holes at the four corners. It is secured to the ground with bolts. This design ensures the device is stably installed on the ground, preventing loosening or tilting due to uneven ground or external impacts, ensuring a stable charging line connection, and avoiding dangers such as power outages and short circuits.

[0027] The charging box 3 is mounted on top of the column 1 and is used to house the electrical components related to charging. The electronic display screen 4 embedded in its front end can display information such as charging status, power level, and cost, providing users with intuitive operation prompts, making it easier for users to understand the charging process and improving the user experience.

[0028] External cable 5 and power supply cable 8: External cable 5 passes through column 1 and connects to the external power supply line, responsible for introducing external power into the charging device. Power supply cable 8 connects charging box 3 and charging gun 9, transmitting electrical energy to charge the trolley.

[0029] The connecting block 6 on the column 1 is used to install the clip 7. The clip 7 is an irregular L-shaped clip and is set in pairs in opposite directions. Its function is to hang and wrap the power supply cable 8 to prevent the cable from being dragged on the ground, reducing the risk of being run over and worn by vehicles. At the same time, it can also keep the surrounding environment clean, prevent the cable from obstructing the passage of the parking lot, and avoid safety hazards such as tripping pedestrians and scratching vehicles.

[0030] The charging gun 9 is the direct operating component for charging the electric vehicle. One end of the connecting rope 10 is connected to the side wall of the charging gun 9, and the other end is connected to the cap 11, facilitating the removal of the cap 11. The shape and size of the cap 11 are adapted to the interface of the charging gun 9, and the cap 11 can cover the interface of the charging gun 9 when not charging. The electromagnetic coil 12 on the front side wall of the charging gun 9 corresponds to the iron block 13 at the front of the cap 11. Utilizing the magnetic attraction between the electromagnetic coil 12 and the iron block 13, the cap 11 is tightly fitted to the interface of the charging gun 9, effectively preventing dust, debris, and moisture from entering, protecting the internal metal contacts of the charging gun 9 interface, ensuring charging efficiency and stability, and reducing the occurrence of malfunctions such as poor contact, charging interruption, or abnormal overheating.

[0031] When the electric vehicle charging device is in operation, the external cable 5 runs through the column 1 and connects to the external power supply line to power the entire device. The electronic display screen 4 on the charging box 3 is used to display charging information and operation prompts. In use, the charging gun 9 is removed from the clip 7. The clip 7 is an irregular L-shaped clip that is set in pairs in opposite directions, which can effectively hook and wrap the power supply cable 8 to prevent the cable from being dragged around. When the charging gun 9 interface is not in use, the cap 11, connected by the connecting rope 10, is tightly attached to the charging gun 9 interface by the magnetic attraction between the electromagnetic ring 12 on the front side wall of the charging gun 9 and the iron block 13 at the front end of the cap 11, preventing dust, debris and moisture from entering. The column 1 is made of flat U-shaped stainless steel, and the bottom mounting plate 2 is fastened to the ground by bolts in the mounting positioning holes at the four corners, ensuring the overall structure of the device is stable, reducing the risk of damage to the device from vehicle collisions or external impacts, and ensuring that the charging process is safe and stable.

[0032] like Figure 1 As shown, in some embodiments, the column 1 is a flat U-shaped structure made of stainless steel; the flat U-shaped design not only meets structural and functional requirements but also has a certain aesthetic appeal. Its unique appearance makes the charging device visually simpler and smoother, better integrating it with modern urban environments and various parking facilities.

[0033] like Figure 1 As shown, in some embodiments, the mounting plate 2 is provided with mounting positioning holes at its four corners, and the mounting plate 2 is fastened to the ground by bolts through the mounting positioning holes; the setting of the mounting positioning holes provides a clear positioning standard for the installation process. When installing the charging device, the construction personnel can quickly and accurately determine the position of the mounting plate 2 on the ground based on these positioning holes, avoiding installation deviations.

[0034] like Figure 1 As shown, in some embodiments, the external cable 5 passes through the column 1 and is connected to the external power line; the column 1 serves as a channel for the external cable 5, providing a clear wiring path for construction personnel during installation, facilitating cable laying and connection operations, and reducing installation difficulty.

[0035] like Figure 1 As shown, in some embodiments, the clip 7 is an irregular L-shape, with two clips arranged in opposite directions, used for hanging and winding the power supply cable 8. The two opposing L-shaped clips 7 provide a reasonable winding and storage structure for the power supply cable 8. When the charging gun 9 is not in use, the power supply cable 8 can be neatly hung and wound on the clips 7, preventing the cable from being scattered on the ground. This not only prevents the cable from being run over by passing vehicles or stepped on by pedestrians, reducing the risk of cable damage and extending the cable's service life, but also keeps the charging area clean and orderly, reducing safety hazards such as tripping pedestrians and scratching vehicles caused by messy cables.

[0036] like Figure 3 As shown, in some embodiments, the shape and size of the cap 11 are adapted to the shape and size of the interface of the charging gun 9; the two are precisely adapted to each other, so that the cap 11 can fit tightly on the interface of the charging gun 9, forming a good sealing effect.

[0037] like Figure 3 As shown, in some embodiments, the installation positions of the electromagnetic coil 12 and the iron block 13 correspond; when the electromagnetic coil 12 is energized, it generates magnetism and attracts the iron block 13 at the corresponding position. This magnetic attraction allows the cap 11 to be tightly attached to the charging gun 9 interface.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
