Description

Technical Field

[0001] This utility model relates to the field of electric vehicle fast charging pile technology, specifically an outdoor anti-freeze electric vehicle fast charging pile structure. Background Technology

[0002] Outdoor antifreeze electric vehicle fast charging stations need to operate stably in low-temperature environments (-40℃ to -30℃). They are usually equipped with a constant temperature structure to save the preheating time of the charging plug when charging electric vehicles is needed, and to prevent condensation from forming on the charging plug when it is in use and affecting charging safety.

[0003] However, existing outdoor anti-freezing electric vehicle fast charging pile structures, in order to prevent freezing, usually maintain a constant temperature for the charging plug to ensure that it is not affected by the low temperature environment, which may cause preheating waiting time for charging and condensation that could lead to charging safety issues. However, when the operator takes the charging plug out of the constant temperature environment and inserts it into the car for charging, the low temperature outdoor environment and the heat carried by the charging plug cause heat loss due to heat conduction with the low outdoor temperature. At this time, the charging head will not only produce condensation that could cause electrical safety hazards, but also prolong the charging time due to the low temperature. Utility Model Content

[0004] This utility model provides an outdoor anti-freezing fast charging pile structure for electric vehicles, which has the advantages of ensuring a continuous constant temperature at the charging end to avoid condensation and power accidents, and improving charging efficiency. It solves the problem of existing outdoor anti-freezing fast charging pile structures for electric vehicles. In structures designed to prevent freezing, the charging plug is usually kept at a constant temperature to ensure that it is not affected by the low temperature environment, which may cause preheating waiting time and condensation that may cause charging safety issues. However, when the operator takes the charging plug out of the constant temperature environment and inserts it into the car for charging, the low temperature outdoor environment and the heat carried by the charging plug cause heat loss due to heat conduction with the low outdoor temperature. At this time, the charging head will not only produce condensation and cause power safety hazards, but also prolong the charging time due to the low temperature.

[0005] To ensure a constant temperature at the charging end to prevent condensation and electrical accidents, and to improve charging efficiency, this utility model provides the following technical solution: an outdoor antifreeze electric vehicle fast charging pile structure, including a protective shell, a charging pile installed on the inner wall of the protective shell, a temperature sensor and a controller installed on one side of the protective shell, the temperature sensor and the controller being electrically connected, the charging pile being connected to a charging head via the connecting line, a temperature-regulating component provided on one side of the protective shell, and a charging antifreeze component provided on the outer surface of the charging head.

[0006] As a preferred embodiment of the present invention, the constant temperature component includes a placement chamber, a door is rotatably connected to one side of the placement chamber, and a PTC heating film for maintaining the internal temperature is installed on the inner wall of the placement chamber.

[0007] As a preferred embodiment of this utility model, the placement compartment is fixedly installed on the inner wall of one side of the protective shell, and a placement rack for conveniently preventing the charging head from being placed is also fixedly installed on the upper part of the inner wall of the placement compartment.

[0008] As a preferred technical solution of this utility model, the charging antifreeze component includes a sealed chamber, which is installed on the outer surface of the charging head. An installation tube is installed on the inner wall of the sealed chamber, and a PTC corrugated heating element is installed on the inner wall of the installation tube. A miniature fan is provided on one side of the PTC corrugated heating element to blow the heat of the PTC corrugated heating element to the charging head insertion end to keep it at a constant temperature.

[0009] As a preferred embodiment of this utility model, the controller is electrically connected to the PTC heating film, the controller is electrically connected to the PTC corrugated heating element, and the controller is electrically connected to the micro fan.

[0010] As a preferred technical solution of this utility model, the hatch is controlled by a knob to open and close the placement compartment, and one end surface of the sealed compartment is provided with multiple output ports, each of which corresponds to an installation tube.

[0011] Compared with the prior art, this utility model provides an outdoor anti-freeze electric vehicle fast charging pile structure, which has the following beneficial effects:

[0012] This outdoor antifreeze electric vehicle fast charging station structure uses a controller and temperature sensor to work together to sense the outdoor temperature and achieve precise temperature control of the PTC heating film and PTC corrugated heating element. Then, the enclosed space of the compartment and door reduces heat loss and ensures the constant temperature of the connecting wires and charging head, eliminating the need for preheating time. Subsequently, a micro fan continuously blows the heat from the PTC corrugated heating element to the insertion end of the charging head, ensuring that the charging head is not affected by low temperature condensation and slowed charging efficiency in outdoor environments.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figures 1-5 This utility model discloses an outdoor antifreeze electric vehicle fast charging pile structure, including a protective shell 1, a charging pile 12 installed on the inner wall of the protective shell 1, a charging head 14 connected to the charging pile 12 via a connecting cable 13, a temperature-regulating component 2 provided on one side of the protective shell 1, and a charging antifreeze component 3 provided on the outer surface of the charging head 14, wherein:

[0024] The charging antifreeze component 3 includes a sealed chamber 30, which is installed on the outer surface of the charging head 14. An installation tube 32 is installed on the inner wall of the sealed chamber 30, and a PTC corrugated heating element 33 is installed on the inner wall of the installation tube 32. A miniature fan 34 is provided on one side of the PTC corrugated heating element 33 to blow the heat of the PTC corrugated heating element 33 to the insertion end of the charging head 14 to keep it at a constant temperature.

[0025] It should be noted that the entire antifreeze component is installed at one end of the charging head 14, and the output end of the micro fan 34 in the antifreeze component corresponds to the output port 31, and the output port 31 corresponds to the charging end of the charging head 14.

[0026] Furthermore, the constant temperature component 2 includes a placement chamber 20, a door 23 is rotatably connected to one side of the placement chamber 20, and a PTC heating film 21 for maintaining the internal temperature is installed on the inner wall of the placement chamber 20.

[0027] Furthermore, a temperature sensor 10 and a controller 11 are installed on one side of the protective housing 1, and the temperature sensor 10 and the controller 11 are electrically connected.

[0028] PTC heating film 21 is a flexible heating element based on positive temperature coefficient PTC ceramic material, and has a thin film structure.

[0029] The PTC corrugated heating element 33 is a high-efficiency heat dissipation heating element composed of a PTC ceramic heating element and an aluminum tube.

[0030] When the user approaches the charging station, they manually rotate the knob on the outside of the placement compartment 20 to open the door 23. At this time, the PTC heating film 21 is activated by the controller 11, continuously heating the inside of the placement compartment 20 to ensure that the temperature inside the compartment is maintained within the set range, such as above 5°C. The temperature sensor 10 monitors the ambient temperature in real time. If the ambient temperature is lower than the threshold, such as 0°C, it sends a signal to the controller 11 to increase the heating power.

[0031] Example 2

[0032] Based on the above embodiment 1, please refer to Figures 3-5 The controller 11 is electrically connected to the PTC heating film 21, the controller 11 is electrically connected to the PTC corrugated heating element 33, and the controller 11 is electrically connected to the micro fan 34.

[0033] Furthermore, the placement compartment 20 is fixedly installed on one side of the inner wall of the protective shell 1, and a placement rack 22 for conveniently preventing the charging head 14 from being placed on the upper part of the inner wall of the placement compartment 20 is also fixedly installed.

[0034] Furthermore, the hatch 23 is controlled by a knob to open and close the placement compartment 20. One end surface of the sealed compartment 30 has multiple outlets 31, each of which corresponds to an installation tube 32.

[0035] It should be noted that: according to Figure 6 It can be seen that the other end of the mounting pipe 32 is provided with an air inlet, which is used to cooperate with the air intake of the micro fan 34, so that the micro fan 34 can blow out the heat emitted by the PTC corrugated heating element 33.

[0036] When the user inserts the charging head 14 into the electric vehicle's charging port, the temperature sensor 10 continuously monitors the temperature of the insertion end of the charging head 14. If the temperature is lower than a safe value, such as -5℃, the controller 11 increases the power of the PTC corrugated heating element 33, and the micro fan 34 accelerates the hot air circulation. The constant temperature component 2 maintains the internal temperature of the placement chamber 20, ensuring that the unused charging head 14 is always in a preheated state. The charging antifreeze component 3 continuously heats the insertion end of the charging head 14 to prevent the charging interface from shrinking or becoming blocked by ice crystals due to low temperatures.

[0037] The working principle and usage process of this utility model: When the user approaches the charging pile, they manually rotate the knob on the outside of the placement compartment 20 to open the compartment door 23. At this time, the PTC heating film 21 has been activated by the controller 11, continuously heating the inside of the placement compartment 20 to ensure that the temperature inside the compartment is maintained within the set range, such as above 5°C. The temperature sensor 10 monitors the ambient temperature in real time. If the ambient temperature is lower than the threshold, such as 0°C, it sends a signal to the controller 11 to enhance the heating power.

[0038] Inserting the charging head: The user inserts the charging head 14 into the electric vehicle charging port. The temperature sensor 10 continuously monitors the temperature of the insertion end of the charging head 14. If the temperature is lower than the safe value, such as -5℃, the controller 11 increases the power of the PTC corrugated heating element 33, and the micro fan 34 accelerates the hot air circulation.

[0039] Temperature control during charging: The temperature control component 2 maintains the internal temperature of the placement chamber 20, ensuring that the unused charging head 14 is always in a preheated state. The anti-freeze charging component 3 continuously heats the insertion end of the charging head 14 to prevent the charging interface from shrinking or becoming blocked by ice crystals due to low temperatures.

[0040] The system enters a low-power state: based on feedback from the temperature sensor 10, the controller 11 reactivates the heating component only when the ambient temperature is below a safe threshold, thus achieving energy-saving operation.
