Description

Technical Field

[0001] The utility model relates to the field of charging cables, in particular to a low-heat-generating charging gun cable. Background Art

[0002] A charging cable is a type of cable that is mainly used to provide power to devices that need to be charged. It usually has a larger current value to meet the initial large current demand of the device when charging. With the popularization of new energy electric vehicles, the use of new energy cables is becoming more and more extensive. Among them, EV cable is a special cable for new energy vehicles. As a carrier of power transmission, it has two main uses: one is to use charging piles to charge electric vehicles, and the other is to conduct high-voltage current inside electric vehicles.

[0003] EV charging pile cable is a multi-core integrated cable suitable for connecting the charging port and battery, the inside of the battery, the battery and the engine and other devices. These cables have special requirements in design and material selection, such as resistance to high voltage, high temperature, electromagnetic interference, stable signal transmission, etc. At the same time, they also have high wear resistance, oil resistance, waterproof and acid and alkali resistance.

[0004] The heat dissipation design of the charging cable is to solve the heat problem generated during the charging process, thereby improving the safety and stability of charging.

[0005] At present, liquid cooling technology is widely used in the heat dissipation design of charging cables. Liquid-cooled charging cables form a liquid cooling circulation system by setting up a special circulation channel between the cable and the charging gun and adding coolant. This design can provide better heat dissipation effect and keep the charging cable in a constant low-temperature environment throughout the charging process, thereby increasing the charging speed and reducing the safety hazards caused by overheating.

[0006] In addition, some new charging cables also use polymer thermal conductive materials and insulating materials to further improve the heat dissipation effect and safety. These materials can effectively transfer heat from the cable to the external environment, thereby avoiding overheating and safety hazards. In short, the heat dissipation design of the charging cable is to ensure safety and stability during the charging process, increase the charging speed, and reduce safety hazards caused by overheating.

[0007] However, due to the short charging time of current home charging piles and in order to reduce costs, generally only exhaust fans are added inside the charging piles for air cooling, and the temperature of the cable generally relies on natural cooling on the surface, so the cable surface often becomes hot. Utility Model Content

[0008] Based on this, the purpose of the utility model is to provide a low-heating charging gun cable to solve the current technical problem of heating of household charging pile cables.

[0009] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a low-heat charging gun cable is arranged in a charging pile shell, an exhaust fan is arranged inside the charging pile shell, a cable outer tube and an air inlet section outer tube are connected to the outside of the charging pile shell, an air inlet structure is arranged on the outside of the air inlet section outer tube, and a cable core that penetrates into the interior of the charging pile shell is arranged inside the cable outer tube and the air inlet section outer tube.

[0010] By adopting the above technical solution, the charging pile shell is set to protect the internal components, the heat is discharged by the exhaust fan, the cable outer tube and the air inlet section outer tube are used to protect the cable core, the air is taken in by the air inlet structure to dissipate heat, and power is supplied through the cable core.

[0012] By adopting the above technical solution, the hollow space is provided to provide an air duct, so that wind enters from the outside and accelerates the flow of the cable core, thereby taking away the heat of the cable core. The existence of the hollow space is ensured by the bracket, and the impact of external collision on the interior is further reduced.

[0013] The utility model is further configured such that the air inlet structure includes a spring shaft and a baffle, a plurality of groups of the spring shafts are arranged on the outside of the outer tube of the air inlet section, the spring shafts are connected to the baffles matched with the outer tube of the air inlet section, and the outer tube of the air inlet section is provided with air holes matched with the baffles.

[0014] By adopting the above technical solution, the spring rotating shaft is set so that the baffle can be close to the outer tube of the air inlet section in the absence of negative pressure, thereby reducing the entry of debris. When the exhaust fan is running, the airflow flows into the outer tube of the air inlet section to form negative pressure, and the negative pressure drives the baffle to retract, thereby allowing the external airflow to enter the interior from the air hole.

[0015] The utility model is further configured such that the opening direction of the spring shaft, the baffle and the outer tube of the air inlet section is oriented toward the outer shell of the charging pile, and the opening direction of the spring shaft and the baffle is to flip and open toward the inner side of the outer tube of the air inlet section.

[0016] By adopting the above technical solution, the opening direction is set to adjust the receiving direction of the baffle opening, reducing the amount of negative pressure required to drive the baffle opening, so that the airflow can push the baffle open more easily.

[0017] The utility model is further configured that a hand-held handle is provided on the side of the outer tube of the air inlet section away from the outer shell of the charging pile, and a charging head matching with the cable core is provided on the inner side of the hand-held handle.

[0018] By adopting the above technical solution, the provided hand-held handle is convenient for the user to hold and insert into the charging port, and the charged object can be charged through the charging head.

[0019] The utility model is further configured that a power supply component cooperating with the cable core is arranged inside the shell of the charging pile.

[0020] By adopting the above technical solution, the power supply component is provided to supply power to the entire device.

[0021] To sum up, the utility model uses an exhaust fan to dissipate heat and exhaust air. The hollow space provided provides an air duct, so that wind enters from the outside and accelerates the flow of the cable core. When the exhaust fan is running, the airflow flows into the outer tube of the air inlet section to form a negative pressure, and the negative pressure drives the baffle to shrink inward, thereby allowing the external airflow to enter the interior from the air hole and take away the heat of the cable core.

[0027] 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. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0028] The following describes an embodiment of the utility model based on its overall structure.

[0029] A low-heat charging gun cable is arranged in a charging pile housing 1, an exhaust fan 2 is arranged inside the charging pile housing 1, a cable outer tube 7 and an air inlet section outer tube 6 are connected to the outside of the charging pile housing 1, an air inlet structure is arranged on the outside of the air inlet section outer tube 6, and a cable core 8 that penetrates into the interior of the charging pile housing 1 is arranged inside the cable outer tube 7 and the air inlet section outer tube 6.

[0030] During installation, the exhaust fan 2 is installed inside the charging pile housing 1. After assembling the power supply component 3 and the cable core 8, the bottom is encapsulated and sealed with sealant or a sealing ring to ensure the sealing so that when the exhaust fan 2 is running, there is only the cable outer tube 7 at the air inlet, preparing for the negative pressure required for subsequent heat dissipation.

[0031] During installation, the number of brackets 11 is adjusted according to the usage scenario. The brackets 11 can further enhance the buffer protection based on the strength of the cable outer tube 7 and the air inlet section outer tube 6. It can also maintain the continuity of the hollow space, prevent the cable outer tube 7 and the air inlet section outer tube 6 from deforming and blocking the air duct, and ensure smooth air intake and heat dissipation.

[0032] It is worth mentioning that during installation, the direction of the air inlet outer tube 6 is adjusted to adjust the opening direction of the baffle 10 to reduce the negative pressure required to drive the baffle 10 to open, so that the airflow can push the baffle 10 open more easily.

[0033] Before use, the external circuit of the power supply component 3 is turned on, and the user holds the handle 5 and inserts it into the charging port, and connects the charged object with the cable core 8 and the power supply component 3 through the charging head 4, and then prepares for charging.

[0034] When charging starts, the exhaust fan 2 performs heat dissipation and exhausts air. The hollow space provided provides an air duct, allowing air to enter from the outside and accelerate the flow of the cable core 8. When the exhaust fan 2 is running, the air flow is sucked by the exhaust fan 2, and a negative pressure is formed in the outer tube 6 of the air inlet section. The negative pressure drives the baffle 10 to retract, thereby allowing the external air flow to enter the interior from the air hole and take away the heat of the cable core 8.

[0035] On the basis of the above structure, in this embodiment, a hollow space is provided between the cable core 8 and the cable outer tube 7 and the air inlet section outer tube 6. The hollow space provides an air duct, so that wind enters from the outside and accelerates the flow of the cable core 8, thereby taking away the heat of the cable core 8. A plurality of groups of brackets 11 are connected between the cable core 8 and the cable outer tube 7 and the air inlet section outer tube 6. The brackets 11 ensure the existence of the hollow space and further reduce the impact of external collisions on the interior.

[0036] On the basis of the above structure, in this embodiment, the air inlet structure includes a spring shaft 9 and a baffle 10. A plurality of groups of the spring shafts 9 are arranged on the outside of the air inlet section outer tube 6. The spring shafts 9 are connected to the baffles 10 that cooperate with the air inlet section outer tube 6. The air inlet section outer tube 6 is provided with air holes that cooperate with the baffles 10. The spring shafts 9 are arranged so that the baffles 10 can be close to the air inlet section outer tube 6 in the absence of negative pressure to reduce the entry of debris. When the exhaust fan 2 is running, the airflow flows into the air inlet section outer tube 6 to form a negative pressure, and the negative pressure drives the baffles 10 to retract, thereby allowing the external airflow to enter the interior from the air holes.

[0037] On the basis of the above structure, in this embodiment, the opening direction of the spring shaft 9 and the baffle 10 and the air inlet section outer tube 6 is oriented towards the charging pile housing 1, and the opening direction of the spring shaft 9 and the baffle 10 is to flip and open toward the inner side of the air inlet section outer tube 6. The opening direction is set to adjust the opening direction of the baffle 10, thereby reducing the negative pressure required to drive the baffle 10 to open, so that the airflow can push the baffle 10 open more easily.

[0038] On the basis of the above structure, in this embodiment, a handle 5 is provided on the side of the outer tube 6 of the air inlet section away from the charging pile housing 1. The handle 5 is convenient for users to hold and insert it into the charging port. A charging head 4 that cooperates with the cable core 8 is provided on the inner side of the handle 5, and the charged object is charged through the charging head 4.

[0039] On the basis of the above structure, in this embodiment, a power supply component 3 cooperating with the cable core 8 is arranged inside the charging pile housing 1, and the entire device is powered by the arranged power supply component 3.
