Description

Technical Field

[0001] The present invention relates to the field of charging piles, and in particular to a multifunctional protective dual-gun charging pile. Background Art

[0002] With the global advocacy for green travel, electric vehicles (EVs) are experiencing rapid market growth due to their environmental and energy-saving advantages. As a key energy source for EVs, the popularity and user experience of charging stations directly impact the development of the EV industry. Dual-gun charging stations, capable of simultaneously charging two EVs, significantly improve the efficiency of charging infrastructure and are widely used in public parking lots, highway service areas, and other locations. Existing dual-gun charging stations suffer from several drawbacks in practice. They lack a protective mechanism for the charging gun. As the core component connecting the charging station to the EV, the charging gun is exposed to the external environment for extended periods. In humid environments, its insulation performance degrades significantly, significantly increasing the risk of electric shock if accidentally touched. Furthermore, the charging gun interface is susceptible to intrusion by moisture, dust, or other foreign matter, causing short circuits. This can not only damage the charging equipment but also potentially lead to serious safety incidents such as fires. Daily physical impact, such as collisions and squeezing, often loosens internal wiring and cracks the charging gun's casing, compromising its proper operation, shortening its service life, and increasing maintenance costs. Improving these issues has become a pressing issue for those skilled in the art. Summary of the Invention

[0003] In order to make up for the above shortcomings, the present invention provides a multifunctional protective dual-gun charging pile, which aims to improve the defects of the existing dual-gun charging piles in actual use. The existing dual-gun charging piles lack a charging gun protection mechanism. The charging gun is the core component connecting the charging pile and the electric vehicle. It is directly exposed to the external environment for a long time. In a humid environment, its insulation performance is easily reduced. Once it is accidentally touched, the risk of electric shock accidents increases significantly, posing a serious threat to personal safety. At the same time, the charging gun interface is also easily invaded by moisture, dust or other foreign matter, causing a short circuit in the circuit, which will not only damage the charging equipment, but may also cause serious safety accidents such as fire. Daily physical collisions, extrusion and other external forces often cause the internal circuit of the charging gun to loosen and the outer casing to break, thereby affecting its normal use, shortening its service life, and increasing equipment maintenance costs.

[0004] The present invention is implemented as follows: a multifunctional protective dual-gun charging pile includes a dual-gun charging pile body, a charging gun protection mechanism and a limiting mechanism are installed on one side of the dual-gun charging pile body, the charging gun protection mechanism is fixed and limited by the limiting mechanism, and an anti-collision mechanism is installed on one side of the dual-gun charging pile body.

[0005] In the preferred technical solution of the present invention, the charging gun protection mechanism includes a protection box, the bottom end and one side of the protection box are opened, guide blocks are installed on both sides of the protection box, a guide rod is installed on one side of the dual-gun charging pile body, the guide rod is provided with a guide groove, the guide block is slidably connected in the guide groove, an external holder is installed on one side of the protection box, and an avoidance groove is provided on one side of the external holder. The protection box is used to protect the charging gun and the charging gun cable placement tray. When the charging gun is not in use, it is fixed by a limiting mechanism. The setting of the protection box can prevent the charging gun from being exposed to the outside for a long time and being accidentally touched by people, especially in a humid environment. Electric shock accidents may occur due to the degradation of insulation performance, threatening personal safety. , and the interface of the charging gun may cause a short circuit due to moisture or other foreign matter, damaging the charging equipment and even causing safety accidents such as fire, and the internal structure of the charging gun may be damaged due to external physical collision, extrusion, etc., resulting in problems such as loose lines and cracked shells, which in turn affect its normal use. At the same time, the charging gun is directly exposed to the external environment and will be affected by natural factors such as direct sunlight, wind and rain, and temperature changes, which will accelerate the aging of the charging gun shell and internal electronic components and shorten its service life. The protective box can better protect the charging gun. When the charging gun needs to be used, the protective box is moved through the guide block and cooperates with the avoidance slot to prevent affecting the use of the charging gun.

[0006] In the preferred technical solution of the present invention, the limiting mechanism includes an installation box, which is installed on one side of the dual-gun charging pile body, a screw is rotatably installed on the inner end of the installation box, a sleeve is threadedly installed on the screw, a limiting block is installed on one side of the sleeve, a fixed block is installed on the bottom end of the protective box, and a connecting groove is provided on the upper end of the installation box to cooperate with the fixed block, the sleeve slides through the connecting groove, and a fixing groove is provided on one side of the fixed block to cooperate with the limit block, and the protective box is preliminarily connected through the fixing block to cooperate with the connecting groove.

[0009] In a preferred technical solution of the present invention, one end of the installation rod rotates and passes through the installation box, and a handle is installed at one end of the installation rod.

[0010] In a preferred technical solution of the present invention, a slider is installed at one end of the sleeve block, a slide groove is provided at the inner end of the installation box, and the slider is slidably connected in the slide groove to improve the stability of the slider when moving.

At the same time, it cooperates with the charging gun protection mechanism and the anti-collision mechanism to realize the multifunctional protection of the device.

[0013] The beneficial effects of the present invention are as follows: the present invention obtains a multifunctional protective dual-gun charging pile through the above design. When in use, the protective box is used to protect the charging gun. When the charging gun needs to be charged, the mounting rod is rotated by the handle. The rotation of the mounting rod causes the worm to drive the worm wheel to rotate, causing the screw to rotate. The rotation of the screw causes the sleeve to drive the limit block to move, so that the limit block is no longer fixed in the fixing groove. The protective box is pulled by an external object. After the charging work is completed, the charging gun is returned to its position. The charging gun protection mechanism is fixed by the limiting mechanism. At the same time, the anti-collision plate prevents the car from colliding with the dual-gun charging pile body and causing damage to the dual-gun charging pile body.
