[0002] A charging pile is composed of a current, voltage and power distribution box, which is connected to a charging gun plug through a transmission line. The common power distribution method of DC charging pile on the market is: combine the outputs of several charging modules into a group, and connect the corresponding DC contactor in series at the output end of each group of charging modules, so as to realize power distribution on each bus and output it to the corresponding charging gun muzzle.

[0003] The existing DC charging pile flexible dynamic power distribution device has a box for current, voltage and power distribution, which is directly fixed by a ground pile and neatly planned in the rear area of ​​the parking space. When the vehicle is charging, it can reverse into the parking space and unplug the charging gun to charge. However, the power distribution box has a single shell structure, and a large number of structural parts and electrical parts are assembled inside the box-shaped shell. When the vehicle is reversing, different drivers may be distracted, have blurred vision, misjudge the distance, or even step on the wrong brake pedal with a small probability, causing the vehicle to directly hit the box. The impact force of the collision may cause damage to the electrical components inside the equipment, making the entire charging pile unusable. The vehicle itself will also be damaged, causing serious losses.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a flexible dynamic power distribution device for a DC charging stack is proposed. Utility Model Content

[0011] Preferably, a base is fixedly mounted on the bottom end of the power distribution box, and a heat dissipation grille is arranged above the rear side of the surface of the power distribution box.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-Figure 3 As shown, a flexible dynamic power distribution device for a DC charging stack includes a power distribution box 1, a control panel 2 is fixedly installed on the upper front side of the surface of the power distribution box 1, outlet boxes 3 are fixedly arranged on the upper left and right sides of the surface of the power distribution box 1, charging output terminals 4 are plugged in at the lower left and right sides of the surface of the power distribution box 1, a transmission line 5 is connected between the charging output terminal 4 and the outlet box 3, and a protective mechanism 6 is arranged at the lower front side of the surface of the power distribution box 1.

[0022] By adopting the above technical solution, the charging output terminal 4 is connected to the vehicle charging port, and the current is distributed through the power distribution box 1 for voltage distribution, and then powered through the transmission line 5; the protection mechanism 6 can be used to protect the power distribution box 1 from collision.

[0023] Furthermore, the protection mechanism 6 includes a damping spring rod 601 fixedly installed below the front side of the surface of the power distribution box 1, and the damping spring rod 601 is composed of a damper and a telescopic spring.

[0024] By adopting the above technical solution, in the damping spring rod 601, the collision force can be buffered by utilizing the contraction of the damper, wherein the telescopic spring can extend and reset the entire damping spring rod 601.

[0025] Furthermore, the protection mechanism 6 also includes a same impact plate 602 fixedly installed at the front end of the damping spring rod 601 , and a guide rod 603 is fixedly arranged in a groove on the rear side of the surface of the impact plate 602 .

[0026] By adopting the above technical solution, the impact plate 602 is located in front of the power distribution box 1, and the collision object can only contact the impact plate 602, thereby preventing the power distribution box 1 from being bumped.

[0027] Furthermore, the protection mechanism 6 also includes a slider 604 slidably arranged on the left and right sides of the surface of the guide rod 603, and a thrust spring 605 is fixedly installed on the opposite side of the surface of the slider 604 on the outside of the guide rod 603, and the end of the thrust spring 605 is fixedly connected to the inner surface of the groove of the impact plate 602.

[0028] By adopting the above technical solution, the guide rod 603 makes the movement of the slider 604 more stable, and the elastic thrust generated by the thrust spring 605 after being squeezed by the slider 604 can perform secondary buffering on the impact collision force.

[0029] Furthermore, the protection mechanism 6 also includes a movable rod 606 rotatably mounted at the rear end of the slider 604. The movable rod 606 is inclined toward the middle correspondingly on the left and right sides. The rear end of the movable rod 606 is rotatably connected to the surface of the power distribution box 1 through the same rotating shaft seat.

[0030] By adopting the above technical solution, the impact plate 602 is driven by the movable rod 606, so that when it is impacted, it will push the slider 604 to move.

[0031] Furthermore, a base 7 is fixedly mounted on the bottom end of the power distribution box 1 , and a heat dissipation grille 8 is arranged on the upper rear side of the surface of the power distribution box 1 .

[0032] By adopting the above technical solution, the heat dissipation grille 8 ventilates and dissipates heat inside the box.

[0033] Furthermore, a convergence groove 9 is provided on the rear side of the surface of the power distribution box 1 below the heat dissipation grille 8 , a movable frame 10 is rotatably mounted on the inner surface of the convergence groove 9 , and a counterweight 11 is fixedly mounted on the bottom end of the movable frame 10 .

[0034] By adopting the above technical solution, if the power distribution box 1 is hit and tilts to the rear, the entire box body will be tilted, and the movable frame 10 will rotate out of the convergence groove 9 using its own weight, always maintaining a vertical downward state to provide support, thereby preventing the power distribution box 1 from falling directly and being damaged; the counterweight 11 increases the bottom weight of the movable frame 10, ensuring that the movable frame 10 can maintain a vertical support more effectively.

[0035] Working principle: When using the DC charging stack flexible dynamic power distribution device, first, when the vehicle enters the charging position for charging, pull out the charging output terminal 4 and connect it to the vehicle charging port, use the control panel 2 to scan the code or swipe the card to start the power distribution box 1, and select the corresponding power supply port. The power distribution box 1 adjusts the current and voltage, and the adjusted adaptive current is transmitted through the transmission line 5 for charging. If a vehicle does not stop in time when reversing into the charging position and collides with the power distribution box 1, the vehicle will first contact the impact plate 602, causing the impact plate 602 to move backward, squeezing the damping spring rod 601 to contract, and the collision force is buffered for the first time, and the impact plate 602 will also pass through the movable rod 6 06 Push the slider 604 to move to both sides along the guide rod 603, squeezing the thrust spring 605, and using the elastic force of the thrust spring 605 to perform secondary buffering on the collision impact, avoiding excessive reversing and directly colliding with the power distribution box 1, causing the box body to deform and dent. If the collision speed is too fast, the entire pile body will be directly knocked down. When the power distribution box 1 tilts to the rear, the movable frame 10 uses its own weight and the weight of the counterweight 11 to move out of the convergence groove 9, always keeping it vertical with the ground, and supporting the tilted power distribution box 1 from the rear side to avoid the box body from being directly hit and damaged, thereby further enhancing the protection capability of the entire equipment. This is the working principle of the flexible dynamic power distribution device of the DC charging pile.
