Detailed Implementation

[0017] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0018] According to an embodiment of this utility model, a high-voltage DC dual-gun charging pile is provided.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-7 As shown, according to an embodiment of the present invention, the high-voltage DC dual-gun charging pile includes: a body 1; an operation screen 2, disposed on the top of the body 1; a charging protection mechanism 3, symmetrically disposed in the middle of the body 1; a high-voltage charging gun 4, disposed inside the charging protection mechanism 3, and connected to the body 1 via a cable 5; and a cable positioning assembly 6, uniformly disposed on the bottom of the body 1.

[0020] It should be noted that the main body 1 of the dual-gun charging pile includes a rectifier conversion module, a high-voltage output control module, a main control board, and high-voltage contactors and protective switches, etc. The rectifier conversion module converts AC power from the power grid into high-voltage DC power and is the core module of the charging pile. The high-voltage output control unit is used to control the output voltage (wide output voltage range, specifically 300V~1000V, and current up to hundreds of amperes, thus enabling rapid charging of electric vehicle batteries), current, and power distribution to ensure the coordinated operation of the two guns. The high-voltage contactors and protective switches ensure automatic power-off protection under abnormal conditions such as overvoltage, overcurrent, and short circuit.

[0021] In practical applications, the internal control system performs a self-test, checking the equipment status, charging gun connection status, and battery status. Subsequently, the charging pile communicates with the electric vehicle battery management system via CAN or PLC to determine charging parameters. After confirmation by the main controller, the contactor closes, and the AC power is converted to DC output by the rectifier module. The current is then delivered to the charging gun via cable and finally enters the electric vehicle battery. During charging, the system adjusts the voltage and current in real time according to the battery status to prevent overcharging or overheating; this is existing technology and will not be elaborated upon further here.

[0022] In one embodiment, for the aforementioned body 1, a heat dissipation layer 7 is symmetrically arranged on the outer side wall of the body 1. Furthermore, the heat dissipation layer 7 is attached to the side wall of the body 1 (specifically, it can be installed using screws). To improve the heat dissipation efficiency of the heat dissipation layer 7, in specific applications, thermal grease can be applied between the heat dissipation layer 7 and the body 1. In addition, to prevent rainwater from entering, a sealing strip can be installed between the edge of the heat dissipation layer 7 and the body 1. This is existing technology and will not be elaborated further here. This effectively improves the heat dissipation performance of the charging pile, helps prevent the equipment from overheating, and ensures stable operation over a long period of time.

[0023] In one embodiment, the charging protection mechanism 3 includes a charging protection chamber 301 symmetrically arranged at the middle of the outer side of the body 1. A plurality of placement slots 302 are evenly formed on the inner circumference of the charging protection chamber 301, and a plurality of first through holes 303 are formed inside the placement slots 302. A charging gun protection assembly 304 is provided between the charging protection chamber 301 and the body 1. The charging gun protection assembly 304 includes a mounting bracket 3041 disposed inside the charging protection chamber 301. A protrusion 3042 is provided, and a fixing post 3043 is provided on one side of the protrusion 3042. Limiting blocks 3044 are provided on both sides of the fixing post 3043. A snap-fit ​​sleeve 3045 is sleeved on the outside of the limiting block 3044. A second through hole 3046 that mates with the limiting block 3044 is provided in the middle of the snap-fit ​​sleeve 3045. A limiting groove 3047 that mates with the limiting block 3044 is provided on the outer side wall of the snap-fit ​​sleeve 3045. A connecting sleeve 3048 that mates with the protrusion 3042 is provided on one side of the snap-fit ​​sleeve 3045. Several snap-fit ​​plates 3049 are provided on the outer circumference of 3048, and a connecting shaft 30410 is provided between two sets of snap-fit ​​plates 3049. Several third through holes 30411 are provided on the inner side wall of the mounting bracket 3041 to mate with the connecting shaft 30410. The connecting shaft 30410 passes through the third through holes 30411 and connects to the first mounting block 30412. A groove 30413 is provided on one side of the first mounting block 30412. A second mounting block 30414 is provided inside the groove 30413. A clamping plate 30415 is provided on one side of the first mounting block 30412. Several first connecting posts 30416 that cooperate with the first through holes 303 are provided on the outer side wall of the first mounting block 30412. The high voltage charging gun 4 is fixed by the movement of several sets of clamping plates 30415. This can effectively prevent the high voltage charging gun 4 from being damaged by external impact or vibration when it is not in use. At the same time, it ensures the stability of the high voltage charging gun 4 when it is working, avoids poor electrical contact or safety hazards caused by loosening or instability, and thus improves the safety and reliability of the charging pile.

[0024] Specifically, the working principle of the charging protection mechanism 3 includes: placing the high-voltage charging gun 4 in the charging protection chamber 301 and pressing the high-voltage charging gun 4. During the pressing process of the high-voltage charging gun 4, the snap-fit ​​sleeve 3045 and the connecting sleeve 3048 will be squeezed. Under the cooperation of the limiting block 3044 and the limiting groove 3047, the snap-fit ​​sleeve 3045 and the connecting sleeve 3048 will move towards the body 1. During the movement of the connecting sleeve 3048, the connecting shaft 30410 will move. During the movement of the connecting shaft 30410, the first mounting block 30412 will move inward, which will in turn drive the second mounting block 30414 and the clamping plate 30415 to move inward, thereby fixing the gun head of the high-voltage charging gun 4.

[0025] In one embodiment, the cable positioning assembly 6 includes a mounting base 601 evenly distributed on the bottom of the outer side of the body 1 (the body 1 has several mounting cavities that mate with the mounting base 601). A fixing frame 602 is provided inside the mounting base 601. A sliding groove 603 is formed in the middle of the fixing frame 602. A sliding plate 604 is provided inside the sliding groove 603. A limiting plate 605 is provided on one side of the sliding plate 604. A turntable 606 is provided in the middle of the fixing frame 602. An arc-shaped groove 607 is provided on the outer circumference of the turntable 606. A second connection that mates with the sliding plate 604 is provided inside the arc-shaped groove 607. One side of the column 608 and turntable 606 is connected to the output end of the servo motor 609 through the fixing bracket 602. In addition, in specific applications, in order to avoid wear and tear on the servo motor 609 during long-term operation, the servo motor 609 is a servo geared motor, thereby ensuring the stability and continuity of the device during operation. The relative movement of the two sets of limiting plates 605 effectively fixes the cable 5, preventing the cable 5 from swinging or being subjected to uneven force during charging, avoiding interference caused by cable 5 damage or dragging, ensuring a firm connection between the high-voltage charging gun 4 and the cable 5, thereby providing a safer and more stable charging environment, and extending the service life of the cable 5.

[0026] The working principle of the cable positioning component 6 includes: starting the servo motor 609 through the operation screen, the output end of the servo motor 609 drives the turntable 606 to rotate, which in turn drives the second connecting column 608 to move inside the arc groove 607. During the movement of the second connecting column 608, the sliding plate 604 moves inside the sliding groove 603. In turn, the relative movement of the two sets of limiting plates 605 effectively fixes the cable 5, preventing the cable 5 from swinging or being subjected to uneven force during charging.

[0027] In practical applications, the servo motor 609 is started via the operation screen 2. By setting the clamping threshold of the servo motor 609 related to the cable tension or load, the torque limit of the servo motor 609 can be adjusted to prevent the servo motor 609 from overloading during operation due to excessive load. This avoids situations where the clamping of the cable 5 is too tight or too loose. This is existing technology and will not be elaborated on here. In addition, the number of cable positioning components 6 can be set according to the length of the cable 5, such as 4, 6, or 8 groups, etc.

[0028] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0029] In practical applications, the main body 1 is operated and monitored through the control panel 2 located on the top. The charging protection mechanism 3 (the working principle of the charging protection mechanism 3 is as described above) is symmetrically arranged in the middle of the outer side of the main body 1, which serves to protect the charging gun 4. The high-voltage charging gun 4 is connected to the main body 1 through the cable 5, thereby enabling the charging of electric vehicles. During the charging process, the high-voltage charging gun 4 is fixed and protected by the charging protection mechanism 3 to ensure that the charging gun works stably and safely. At the same time, the cable positioning component 6 (the working principle of the cable positioning component 6 is as described above) is evenly arranged on the bottom of the outer side of the main body 1 to prevent the cable from being pulled or interfered with during the charging process, and to ensure a stable connection between the cable and the charging gun.

[0030] In summary, by utilizing the above-mentioned technical solutions of this utility model, the present utility model effectively fixes the cable 5 by setting the cable positioning component 6 and the relative movement of two sets of limiting plates 605, thereby preventing the cable 5 from swinging or experiencing uneven force during charging, avoiding interference caused by cable 5 damage or dragging, ensuring a stable connection between the high-voltage charging gun 4 and the cable 5, thus providing a safer and more stable charging environment, and extending the service life of the cable 5; the present utility model also fixes the high-voltage charging gun 4 by setting the charging protection mechanism 3 and the movement of several sets of clamping plates 30415, effectively preventing the high-voltage charging gun 4 from being damaged by external impacts or vibrations when not in use, while ensuring the stability of the high-voltage charging gun 4 during operation, avoiding poor electrical contact or safety hazards caused by loosening or instability, thereby improving the safety and reliability of the charging pile; the present utility model also effectively improves the heat dissipation performance of the charging pile by symmetrically setting the heat dissipation layer 7 on the outer wall of the body 1, which helps to prevent the equipment from overheating and ensures stable operation for a long time.
