Description

Technical Field

[0001] The utility model relates to the technical field of charging piles, and in particular to a device for thawing and preventing freezing of a charging pile gun seat. Background Art

[0002] As living standards gradually improve, new energy vehicles are increasingly becoming part of people's daily lives. With the widespread adoption of new energy vehicles, charging piles, as crucial supporting facilities, must be able to adapt to a variety of complex environmental conditions. Since charging piles are used outdoors, they are subject to a variety of environmental and climatic conditions, including some with extremely low temperatures. The charging gun holder, a specialized device on the charging pile used to store the charging gun after charging, can easily be infiltrated by rain and snow in freezing temperatures, freezing the gun holder. This can cause the gun tip to become frozen in the holder when the user needs to charge, preventing it from being removed and preventing charging.

[0003] The existing technology is to tilt the gun seat insertion port downward so that rainwater or snowwater cannot be retained, thereby preventing ice from forming. Although this method of tilting the gun seat insertion port downward reduces the retention of rainwater or snowwater to a certain extent and reduces the probability of ice forming, it still has the following defects:

[0004] 1. Since the gun mount insertion port is tilted downward, inserting the gun head into the gun mount becomes inconvenient, affecting the user experience;

[0005] 2. Even if the gun mount insertion port is tilted downward, some rain and snow water will still seep into the gun mount along the surface. In extremely low temperatures, the water will freeze before flowing out of the gun mount.

[0006] 3. The insertion port of the gun mount is tilted downward. When the snow is deep, snow can still enter the gun mount and cause freezing. Utility Model Content

[0007] In order to solve the defects and shortcomings of the prior art, the utility model provides a device for defrosting and preventing freezing of a charging pile gun seat, which has a simple structure and is easy to use.

[0008] To achieve the above-mentioned objectives, the technical solution adopted by the present invention is a device for thawing and preventing ice formation in a charging pile gun seat, comprising a charging gun seat body for placing a charging gun and a charging pile; the charging pile is provided with a receiving cavity for accommodating the charging gun, and also includes a thawing control component, the thawing control component includes a heater for melting ice in the charging gun, a protective device and a control board; the heater is installed on the charging gun, and a control switch and a temperature probe are installed on the control board, one end of the protector is electrically connected to the control switch, and the other end is electrically connected to the heater through a power cord.

[0009] Furthermore, a mounting seat is provided at one end of the charging gun facing the charging gun seat body, and the heater is fixedly connected to the mounting seat.

[0010] Furthermore, the thawing control component also includes a power supply, one end of the power supply is electrically connected to the control switch, and the other end is electrically connected to the heater.

[0013] Beneficial effects of the utility model:

[0014] The present utility model provides a device for defrosting and preventing freezing of the charging pile gun seat. By arranging a heater on the charging gun, the charging gun seat body is heated. It is used to solve the problem that the electric vehicle charging gun seat cannot be used normally due to freezing in cold weather, and it can also prevent freezing. A manual start method can be provided through the panel. The user can immediately start the heating when the charging gun seat body is found to be frozen, quickly solving the problem and avoiding long waits for natural thawing. By using a temperature probe to monitor the ambient temperature in real time, the charging pile can automatically turn on the heating function according to the preset temperature threshold, thereby keeping the charging gun seat dry in a low temperature environment, preventing freezing and ensuring that it is available at any time. At the same time, the control panel can dynamically adjust the heating time and intensity according to different temperature conditions, which can not only ensure an effective antifreeze effect, but also maximize energy savings and reduce unnecessary power consumption. Such a design not only improves the user experience, but also reflects concern for environmental protection.

[0022] The utility model provides a device for thawing and preventing freezing of a charging pile gun seat.

[0023] In the embodiment of the present utility model, Figure 1-3 As shown, the device for thawing and preventing ice formation of the charging pile gun seat includes a charging gun seat body 2 for placing the charging gun 1 and a charging pile (not shown); the charging pile is provided with a receiving cavity for accommodating the charging gun seat body 2, and also includes a thawing control component 3, the thawing control component 3 includes a heater 31 for melting the ice in the charging gun seat body 2, a protector 32 and a control board 33; the heater 31 is installed on the charging gun 1, and the control board 33 is installed with a control switch 4 and a temperature probe 5, one end of the protector 32 is electrically connected to the control switch 4, and the other end is electrically connected to the heater 31 through a power cord.

[0024] In this embodiment, a mounting seat 6 is provided at one end of the charging gun 1 facing the charging gun base body 2 , and the heater 31 is fixedly connected to the mounting seat 6 .

[0025] In this embodiment, the thawing control component 3 further includes a power supply, one end of which is electrically connected to the control switch 4 , and the other end of which is electrically connected to the heater 31 .

[0026] In this embodiment, the device for defrosting and preventing freezing of the charging pile gun seat further includes a panel 7 , which is in communication with the control board 33 , and has a display unit and operation keys.

[0027] In this embodiment, a placement cavity 21 for accommodating the charging gun 1 is provided on the charging gun seat body 2 , and a drainage groove 22 is provided in the placement cavity 21 , and the drainage groove 22 is in the shape of an inclined surface.

[0028] This application heats the charging gun holder body 2 through the heater 31 to defrost or prevent freezing; a manual start method can be provided through the panel 7, and the user can manually start the heating for defrosting; the ambient temperature is collected by the temperature probe 5, and the charging pile can automatically cycle heating in standby mode to prevent freezing; the ambient temperature is collected by the temperature probe 5, and different heating times are set in the program according to different temperatures to improve energy efficiency, shorten the heating time, and enhance the user experience.

[0029] Specifically, the charging gun holder body 2 is installed on the outer shell of the charging pile and is used to accommodate the charging gun 1; when water enters the charging gun holder body 2 and the charging pile is in an extremely low temperature environment outdoors, freezing will occur inside the charging gun holder body 2, making it impossible to pull out the charging gun 1; by adding a heater 31 on the back of the charging gun holder body 2, when the charging gun 1 cannot be pulled out due to freezing, the heater 31 will work to generate heat to melt the ice; at the same time, the user can start the heater 31 by operating on the panel 7, and the panel 7 will upload the start instruction to the control board 33, and the control board 33 will automatically control the switch 4S to close, and the heater 31 is connected to the power supply, thereby entering the heating state.

[0030] The control board 33 collects the ambient temperature through the temperature probe 5, and thus sets different heating times according to different ambient temperatures through the program, such as automatically stopping heating after 20 minutes at -40°C, automatically stopping heating after 10 minutes at -30°C, automatically stopping heating after 5 minutes at -20°C, and automatically stopping heating after 2 minutes at -10°C. The specific heating time depends on the power of the heater 31 and should be based on actual experimental data.

[0031] During actual use, the user can choose to manually start the heater 31 based on whether the charging gun holder body 2 is frozen. The program will automatically stop heating according to different ambient temperatures and set different heating times. It can also start self-circulating heating to prevent freezing when the charging pile is in the charging standby state. In the above two operating modes, if the GW port of the control board 33 does not detect the charging gun 1 plug-in signal, it is strictly forbidden to start the heater 31 or interrupt the operation of the heater 31. If the T port of the control board 33 detects that the ambient temperature is greater than 0°C, it is strictly forbidden to start the heater 31 or interrupt the operation of the heater 31. The heater 31 in this application can be of many types, such as a resistance heater 31, including but not limited to a resistance heater 31.

[0032] The protector 32Fuse serves as a circuit load for overload protection. The power supply is used to power the heater 31 , which can be either an AC power supply or a DC power supply. The specific power supply type depends on the specifications of the heater 31 .

[0033] A drainage groove 22 is designed on the charging gun base body 2. The drainage groove 22 is an inclined surface. When the ice in the charging gun base body 2 melts, the water flows out of the gun base along the drainage groove 22 and will not flow into the cabinet.

[0034] Here's how this application works:

[0035] When charging gun 1 becomes frozen inside charging gun holder body 2 and cannot be removed, the heating operation button on panel 7 is pressed, closing control switch 4S on control board 33. This activates heater 31 mounted on the back of charging gun holder body 2. Heat generated by heater 31 is transferred from the back of charging gun holder body 2 to the front of charging gun holder body 2 through heat conduction, thereby melting the ice inside charging gun holder body 2 and allowing charging gun 1 to be removed. Under the control of control board 33, heater 31 automatically activates a heating cycle according to different ambient temperatures, preventing charging gun holder body 2 from freezing while in standby mode.

[0036] In summary, when water enters the charging gun holder body 2 and is pre-cooled and frozen, the thawing control component 3 of the present application can ensure that the charging gun holder body 2 and the charging gun 1 are thawed, and the charging gun 1 can be unplugged and used.

[0037] It should be noted that this application also includes a gun return detection component 8. The purpose of the design of the detection component is to effectively ensure the stability of the charging gun 1 being embedded and fixed in the charging gun holder body 2, while detecting the position of the charging gun 1 in the charging gun holder body 2 and whether it is completely returned to its original position, thereby preventing the charging gun 1 from falling out of the charging gun holder body 2. It further prevents the charging gun 1 from falling out of the charging gun holder body 2, causing wear of the charging gun 1 and posing certain safety hazards. The gun return detection component 8 detects the gun insertion status to ensure that the charging gun holder body 2 does not activate the heating program interlock function when the charging gun 1 is not inserted.

[0038] The gun return detection assembly 8 is installed in the charging gun seat body 2. When the charging gun 1 is inserted into the charging gun seat body 2, the push rod 81 on the gun return detection assembly 8 moves inward to close K, thereby uploading a set of switch signals to the control board 33. At the same time, the gun return detection assembly 8 can be of many types, including but not limited to Figure 4 Type shown.

[0039] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
