Description

Technical Field

[0001] This utility model belongs to the field of charging pile technology, and in particular relates to a hand-push DC charging pile. Background Technology

[0002] In recent years, with the popularization of new energy vehicles and the surge in demand for distributed charging scenarios (such as temporary parking lots, outdoor activities, and emergency power replenishment), traditional fixed charging piles, due to their long deployment cycles and strong dependence on the power grid, are unable to meet the flexible charging needs. Hand-push portable charging devices have become a direction for industry exploration due to their mobility, but existing technologies still have significant shortcomings:

[0003] Currently, most portable charging devices on the market use air-cooling solutions, limiting their power output to 30kW. Forcibly increasing the power would require increasing the size of the cooling module, resulting in excessive weight and necessitating vehicle transport, thus negating the core value of "hand-pushed portability."

[0004] Traditional folding frames sacrifice protective strength to reduce weight, which can easily lead to loosening of internal circuits on bumpy roads, causing charging pile malfunctions. In addition, in order to reduce the internal space of portable charging piles, the charging gun wires are often exposed, which will accelerate the aging and wear of the gun wires and reduce their service life.

[0005] This patent aims to provide a push-type charging station that supports high power output and has efficient heat dissipation capabilities. Furthermore, it features lightweight design, shock absorption, and the ability to conceal and store the charging cable, thus addressing the core pain points of mobile charging scenarios. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a hand-push DC charging pile that can improve the heat dissipation efficiency of the equipment.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a hand-push DC charging pile, including a charging pile body, the charging pile body is provided with a rectifier assembly, the rectifier assembly includes a plurality of rectifier modules and at least two support plates for fixing the rectifier modules, the rectifier assembly also includes a heat dissipation assembly, the heat dissipation assembly includes a fan and an air inlet hood and an air outlet hood respectively connected to both ends of the support plates, one side of the air outlet hood is connected to a fan fixing plate, the fan is installed on the fan fixing plate, the air inlet hood, the air outlet hood and the two support plates form a guide air duct.

[0008] The charging pile body is equipped with a DC control box, which includes a rear concave plate and a front sealing plate. The rear concave plate is equipped with an auxiliary power supply, an electromagnetic lock driver, and a DC meter. The front sealing plate includes an upper small plate and a lower small plate. The upper small plate is equipped with electrical components and plug-in terminals. The lower small plate is equipped with a main control board. The lower small plate is fixed to the DC control box by a hinge.

[0009] The rear recessed plate is connected to a DC output circuit area, which includes a DC contactor, a fuse, and a shunt.

[0010] The bottom of the charging pile body is equipped with several shock-absorbing wheels and at least two height-adjustable support feet. Handles are provided on both sides of the charging pile body, and a cable outlet is provided on one side of the charging pile body.

[0011] The shock-absorbing wheels include two shock-absorbing spring swivel wheels and two shock-absorbing spring directional wheels.

[0012] The rectifier assembly also includes an air inlet window and an air outlet window.

[0013] The charging pile body is equipped with a gun wire storage cover plate, and the gun wire storage cover plate is equipped with a gun wire hook.

[0014] The charging pile body is equipped with a first electrical component group and a second electrical component group.

[0015] The first electrical component group includes a light strip, a display screen, a card reader, an emergency stop button, and a gun wire adapter terminal group.

[0016] The second electrical component group includes an aviation socket, a high-current terminal, and a circuit breaker.

[0017] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0018] 1. The air inlet hood, air outlet hood, and two support plates form a guide air duct. Two fans provide stable airflow, which can simultaneously dissipate heat from multiple rectifier modules, improving heat dissipation efficiency. High-strength anti-slip shock-absorbing wheels and support feet are used to prevent internal circuits from loosening due to vibration during transportation, thus avoiding equipment failure and ensuring safe and reliable transportation.

[0019] 2. Through reasonable internal structural innovation, based on the DC charging principle, the electrical components are arranged according to function, forming relatively independent electrical functional components. The structure is compact, highly integrated, occupies little space, is lightweight, and is easy to maintain. It makes full use of space, hiding the charging gun cable inside the charging pile, solving the problems of cable dragging, aging, and wear, and improving the service life of the charging gun cable. It supports multiple charging modules and independent air duct design to achieve rapid heat dissipation and meet the load requirements of different power.

[0020] 3. The charging pile has a space-efficient overall structure, small size, and light weight. It is a lightweight, shock-absorbing, concealed charging cable, high-power output support, and efficient heat dissipation hand-push charging pile, which meets the core requirements of "hand-push portability".

[0039] Reference Figures 1-13This embodiment provides a push-type DC charging pile, specifically including a charging pile body 1. The charging pile body 1 is provided with a rectifier assembly 3. The rectifier assembly 3 includes a plurality of rectifier modules 33 and at least two support plates 34 for fixing the rectifier modules 33. The rectifier assembly 3 also includes a heat dissipation assembly, which includes a fan 36 and an air inlet hood 32 and an air outlet hood 35 respectively connected to both ends of the support plates 34. One side of the air outlet hood 35 is connected to a fan fixing plate 38. The fan 36 is installed on the fan fixing plate 38. The air inlet hood 32, the air outlet hood 35 and the two support plates 34 form a guide air duct.

[0040] Two support plates 34 are arranged vertically, and multiple rectifier modules 33 are configured thereon.

[0048] Air inlet window 31 and air outlet window 37 are connected to air inlet cover 32 and air outlet cover 35 respectively by screws. Air inlet cover 32 and air outlet cover 35 are fixedly connected to the two side walls of the charging pile body 1 respectively. Air inlet window 31 is located on one side wall of the charging pile body 1, and air outlet window 37 is located on the opposite side wall. Both air inlet window 31 and air outlet window 37 are louvered structures.

[0049] The charging cable storage plate 2 is fixed to the front column. The charging cable storage plate 2 contains a charging cable hook 21 for fixing and suspending the charging cable. The charging cable storage plate 2 can also cover the high-voltage copper busbar to prevent human contact when the charging station door is opened.

[0050] The charging pile body 1 is equipped with a first electrical component group and a second electrical component group 12.

[0051] The first electrical component group includes a light strip 111, a display screen 112, a card reader 113, an emergency stop button 114, and a gun wire adapter terminal group 115.

[0052] The second electrical component group 12 includes an aviation socket 121, a high-current terminal 122, and a circuit breaker 123.

[0053] The first electrical component group is located on the left side of the charging pile body 1, and the second electrical component group 12 is located on the right side of the charging pile body 1.

[0056] When pushing the charging pile over bumpy roads, the shock-absorbing wheels can effectively reduce the bumps of the charging pile and play a role in shock resistance. When the charging pile reaches the designated position, the shock-absorbing spring caster 14 is locked and the support feet 16 are retracted to firmly fix the charging pile to the ground.

[0057] The charging pile body 1 has a charging gun cable outlet 18 on the lower right side. The charging gun cable outlet 18 is fixed to the charging pile body 1 by a self-returning hinge. When the charging pile is charging the charging gun, the front door does not need to be kept open to charge it, so there is no need to worry about safety issues. When charging is finished, open the front door, wrap the charging gun cable around the charging gun cable hook 21, and then close the front door.

[0058] The working principle of the charging pile is as follows: AC power enters the charging pile through the aviation plug and aviation socket 121, is connected to the high current terminal 122 through the cable, and then from the high current terminal 122 is connected to the AC interface of the charging module through the cable. After being converted into DC power by the charging module, it flows out from the DC interface of the charging module, is connected to the DC output circuit area 44 in the DC control box 4 through the cable, and finally reaches the charging gun.

[0059] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
