Description

Technical Field

[0001] The utility model relates to the technical field of charging piles, and in particular to a silent charging pile with an independent air duct. Background Art

[0002] The function of a charging pile is similar to that of a gas pump in a gas station. It can be fixed on the ground or on a wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. It can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. Charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to perform corresponding operations such as charging method, charging time, and cost data printing. The charging pile display can display data such as charging amount, cost, and charging time.

[0003] Invention patent authorization announcement number CN110325013B discloses a charging pile, the charging pile includes a charging pile body and a base arranged at the bottom of the charging pile body, the charging pile body has a housing cavity for installing an electrical module, the side wall of the charging pile body is provided with an air inlet near the upper part, the base is a hollow structure and the side wall of the base is provided with an air outlet, and an air flow channel for heat dissipation of the electrical module is formed between the air inlet and the air outlet. A partition is provided in the housing cavity to separate the housing cavity into an upper housing cavity connected to the air inlet and a lower housing cavity connected to the air outlet, the electrical module includes an IGBT module arranged in the upper housing cavity and an inductor module arranged in the lower housing cavity, a blower is provided in the upper housing cavity, the air outlet of the blower is connected to the air inlet of the radiator air duct of the I GBT module, and the air outlet of the radiator air duct is connected to the lower housing cavity.

[0004] At present, in such charging piles, among the electrical modules installed in the accommodating cavity, the IGBT module, namely the AC / DC module and the DC / DC module, is the module that generates the most heat. Each AC / DC module and DC / DC module is installed on a circuit board respectively. These circuit boards are installed in the bus slots in the accommodating cavity. Generally, there is an AC / DC module and a number of DC / DC modules set according to needs. Although the use of a blower to blow cold air through the IGBT module can take away some of the heat on the AC / DC module and the DC / DC module, although the heat dissipation effect is good, since the air blown by the blower itself is the air outside the accommodating cavity, some dust will enter the radiator air duct and stick to the AC / DC module and the DC / DC module, making it difficult to clean the AC / DC module and the DC / DC module, and even causing a short circuit due to dust adhesion, which is dangerous. Utility Model Content

[0005] In order to make up for the above deficiencies, the utility model provides an independent air duct silent charging pile.

[0006] The utility model is achieved in this way:

[0007] A silent charging pile with an independent air duct comprises a charging pile body and a heat dissipation mechanism, wherein the charging pile body comprises a pile body, a cavity is formed on one side of the pile body, a distribution box is formed on the outer side of the pile body, and a plurality of heat dissipation holes connected to the cavity are formed on the other side of the pile body, and the heat dissipation mechanism comprises a heat dissipation box, which is installed inside the cavity, a mounting cavity is formed on one side of the heat dissipation box, and an air outlet slot connected to the heat dissipation holes is formed on the other side of the heat dissipation box, a heat sink is installed inside the mounting cavity, one side of the heat sink is located inside the distribution box, air inlet slots are formed on both sides of the heat dissipation box, a filter is installed on one side of the air inlet slot, a first motor is installed inside the heat dissipation box, and a turbine is transmission-connected to the output end of the first motor.

[0008] The beneficial effect of adopting the above further scheme is that the IGBT module is installed on the side of the heat sink located inside the cavity through the circuit board, and the heat generated by its operation will be transferred to the heat sink. When the first motor drives the turbine to rotate, the air enters the heat sink through the air inlet slot and flows out of the heat sink through the air outlet slot and the heat dissipation holes, and the heat on the heat sink can be taken away, thereby achieving the purpose of dissipating heat for the IGBT module. At the same time, the circulating air will not contact the IGBT module in the distribution box, so it can prevent dust from sticking to the module.

[0009] Furthermore, sound insulation cotton is installed on the inner wall of the heat dissipation box.

[0010] The beneficial effect of adopting the above further scheme is that the sound insulation cotton can eliminate the noise generated when the first motor drives the turbine to rotate, thereby achieving the purpose of silent heat dissipation.

[0011] Furthermore, a pair of connecting blocks are installed on the inner walls of both sides of the heat dissipation box near the air inlet slot, and a rotating shaft is connected between the pair of connecting blocks through a torsion spring. A pressure strip is installed on the outer side of the rotating shaft, and a clapper is installed at one end of the pressure strip, and the clapper is in contact with the filter.

[0012] Furthermore, the clapper board is provided with sound insulation cotton on one side close to the filter screen.

[0013] Furthermore, the torsion spring is sleeved on both ends of the rotating shaft, and one end of the torsion spring is installed on the outside of the rotating shaft, and the other end of the torsion spring is installed on the side of the connecting block.

[0014] Furthermore, a base is installed on both inner walls of the heat dissipation box, a second motor is installed on one side of the base, an output end of the second motor is transmission-connected with an eccentric wheel, and the eccentric wheel and the other end of the pressure strip are squeezed together.

[0015] The beneficial effect of adopting the above further scheme is that the second motor drives the eccentric wheel to rotate so that it is squeezed with the other end of the pressure strip, so that the clapper is away from the filter. At the same time, the torsion spring accumulates energy. As the second motor drives the eccentric wheel to continue to rotate, the eccentric wheel no longer squeezes the pressure strip. At this time, the torsion spring releases energy, causing the clapper to hit the filter, thereby knocking off the dust particles attached to the filter to ensure the ventilation volume of the filter.

[0016] Furthermore, a fixing seat is installed at the bottom of the pile body, and four groups of fixing holes are opened on the top of the fixing seat.

[0017] The beneficial effect of adopting the above further solution is that the charging pile can be fixed on the ground by passing the bolt through the fixing hole and screwing it into the hole pre-opened on the ground.

[0018] The beneficial effect of the utility model is that the utility model obtains an independent air duct silent charging pile through the above design. The technical solution can achieve the purpose of cooling the module in the distribution box without the module contacting with cold air through the use of independent air duct, thereby preventing dust from sticking to the module and thus improving the service life of the module.
