[0034] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0035] It should be pointed out that the embodiments of the present invention and the technical features therein may be combined with each other without conflict.

[0036] In the process of charging an electric vehicle, especially in the process of charging with a liquid-cooled super charging pile, the charging gun body and the cable are usually at a high temperature due to the large charging current and the long duration of the charging process. In order to prevent the user's hands from being burned when operating the charging gun, such as when unplugging the charging gun, an embodiment of the present invention provides a charging gun 100, including: a charging gun body, a cable 101 connected to the charging gun body, a plurality of temperature sensors, and a display screen 102, such as Figure 1 As shown, one of the multiple temperature sensors is arranged on the handle 103 of the charging gun, and is used to detect the temperature of the handle 103; another of the multiple temperature sensors is arranged in the cable 101, and is used to detect the temperature of the cable 101; the display screen 102 is used to display a warning message indicating that the temperature is too high when the temperature of the handle 103 and / or the cable 101 exceeds a preset threshold. Users usually hold the handle 103 of the charging gun with their hands and unplug the charging gun with force. Therefore, a temperature sensor is arranged on the handle 103 to detect the temperature of the handle 103, and a warning message is displayed on the display screen 102 when the temperature of the handle 103 exceeds the preset threshold. In addition, since the charging gun body is connected to the cable 101, it is inevitable to touch the cable 101 when operating the charging gun, and the temperature of the cable 101 may also be relatively high. In order to reduce the probability of the user's hands or some parts coming into contact with the high-temperature cable 101, when the temperature of the cable 101 is high, a high-temperature warning message is displayed on the display screen 102 to attract the user's attention, so that the user can take heat insulation measures or operate the charging gun later to prevent burns. In an optional embodiment of the present invention, the display form of the warning message includes: text and / or color. Specifically, the warning message may include a high-temperature warning symbol, such as Figure 2 As shown, the lightning symbol is displayed on the display screen 102, which indicates a high temperature warning symbol. In order to be more eye-catching, it can also be set to a red lightning symbol, or a warning message in text form, such as "handle temperature is too high", "cable temperature is too high", etc. Figure 3 shown.

[0037] In an embodiment of the present invention, the display screen is further configured to display a warning message indicating that the temperature of the handle 103 is too high when the temperature of the handle 103 is higher than a first threshold. Since the user needs to hold the handle 103 of the charging gun with the hand, and the user does not need to hold the cable 101. Even if the user touches the cable 101, it is only an occasional touch and not a long-term contact. Therefore, the degree of contact between the user's hand and the handle 103 is different from the degree of contact between the user's hand or other parts and the cable 101. So, the first threshold for triggering the display of the high-temperature warning message for the handle 103 is different from the second threshold for triggering the display of the high-temperature warning message for the cable 101. Among them, the first threshold is 50 °C, and the second threshold is 60 °C. That is to say, when the temperature sensor detects that the temperature at the handle 103 exceeds 50 °C, a warning message indicating that the temperature of the handle 103 is too high is displayed on the display screen to remind the user to pay attention not to be scalded by the handle 103. In addition, in another optional embodiment of the present invention, the display screen is further configured to display a warning message indicating that the temperature of the cable 101 is too high when the temperature of the cable is higher than the second threshold. That is to say, when the temperature sensor detects that the temperature of the cable 101 exceeds 60 °C, a warning message indicating that the temperature of the cable 101 is too high is displayed on the display screen to remind the user to pay attention not to be scalded by the cable 101.

[0038] In addition to displaying the high-temperature warning message, the display screen can also display the temperature of the handle 103 and / or the cable 101, such as Figure 4 and Figure 5 shown, where Figure 4 is the display state of the display screen 102 when the temperature of the handle 103 and / or the cable 101 does not trigger the display of the high-temperature warning message, Figure 5 is the display state of the display screen 102 after the high-temperature warning message is triggered. In an optional embodiment of the present invention, the display screen 102 is further configured to display the temperature of the handle 103 and / or the cable 101, and update the displayed temperature every preset time period. Since the charging process is still ongoing and the temperature of the handle 103 and / or the cable 101 is still changing, in order to ensure that the temperature value displayed on the display screen 102 is consistent with the actual temperature of the handle and the cable 101, the displayed temperature is updated every once in a while. For example, the temperature displayed on the display screen 102 is updated once every 5 seconds, so that the displayed temperature is closer to or consistent with the actual temperature of the handle 103 and the cable 101.

[0039] In addition to issuing a warning message through the display screen 102, an alarm tone can be issued through an alarm device to remind the user that the current temperature of the handle 103 and / or the cable 101 is too high, and to be careful to prevent scalding. In other optional embodiments of the present invention, the charging gun also includes: an alarm device, which is used to issue a warning message in the form of sound when the temperature of the handle 103 and / or the cable 101 exceeds the preset threshold. Among them, the alarm device can use a buzzer. That is, when the temperature of the handle 103 and / or the cable 101 exceeds the preset threshold, a buzzer is issued to remind the user that the current temperature is too high and to be careful to prevent scalding.

[0040] In order to enable the user to notice the warning information displayed on the display screen immediately before operating the charging gun, the display screen is set at a position on the charging gun that is easy for the user to see. In an optional embodiment of the present invention, the display screen 102 is set on the upper surface of the handle 103. For details, please refer to Figures 1-6 In this way, the user can notice the warning information on the display screen before holding the charging gun, reducing the probability of the user being burned.

[0041] The charging gun provided in this embodiment, in addition to displaying the temperature of the handle 103 and the cable 101 to remind the user that the temperature is too high, also provides a heat insulation component 104. When the user is anxious to unplug the charging gun, but dares not touch the handle 103 because the temperature of the handle 103 is too high, the heat insulation component 104 is used to wrap the handle 103 to play a role of heat insulation, so that the user can unplug the charging gun smoothly without being burned or scalded. In an optional embodiment of the present invention, the charging gun also includes: a heat insulation component 104 detachably connected to the charging gun body, wherein the heat insulation component 104 is used to wrap around the handle 103, and the heat insulation component 104 fits the handle 103. Figure 6 The figure shows a schematic diagram of the heat insulation component wrapped around the handle. In order to prevent the display screen from being covered by the heat insulation component, the display screen can be set at a position where the user will not be held when holding the handle and the user can easily view the information displayed on the display screen. Figure 6 In addition, the heat insulating component 104 can be a sheet of heat insulating body wrapped around the handle 103 for a long time; or it can be a sheet of heat insulating body, which is usually hung on one side. When the user uses it, the user wraps the handle 103 with the sheet of heat insulating body, and the user holds the handle 103 through the heat insulating component 104 to isolate the high temperature. The heat insulating component 104 is hung at a predetermined position of the charging gun body when not in use, and is wrapped on the handle 103 when in use, which is beneficial to the heat dissipation of the charging gun body. The heat insulating component 104 is made of rubber material, fiber material or expanded graphite material.

[0042] In an alternative embodiment of the present invention, the charging gun further includes: a heat-insulating coating, wherein the heat-insulating coating at least wraps the handle 103 of the charging gun; preferably, the heat-insulating coating is made of high-temperature ceramic or aluminum. In addition to using the sheet-shaped heat-insulating member 104 to isolate high temperature and prevent the user from being scalded or burned, the high temperature can also be isolated by applying a heat-insulating coating on the handle 103. Among them, preferably, the heat-insulating coating is made of high-temperature ceramic or aluminum.

[0043] In an alternative embodiment of the present invention, an air-cooling component for reducing the temperature of the handle 103 and / or the cable 101, wherein the air-cooling component is configured to start when the temperature of the handle 103 and / or the cable 101 exceeds a preset threshold, and cool the handle 103 and / or the cable 101. Among them, the air-cooling component includes a fan. When the temperature of the handle 103 exceeds a first threshold and / or the temperature of the cable 101 exceeds a second threshold, the fan is started to rotate, and the heat of the handle 103 and the cable 101 is carried away by accelerating the air flow, so as to reduce the temperature of the handle 103 or the cable 101. Among them, the air-cooling component is detachably connected to the outside of the charging gun body or is embedded in the charging gun body. When the user uses the air-cooling component, it needs to be removed and held by hand, and blown against the handle 103 or the cable 101 of the charging gun to reduce the temperature of the handle 103 or the cable 101.

[0044] In other alternative embodiments of the present invention, the charging gun further includes a heat-absorbing component made of a phase change material, wherein the heat-absorbing component is close to the handle 103 and absorbs the heat of the handle 103 when the temperature of the handle 103 rises. The method of cooling the handle 103 and / or the cable 101 also includes using a heat-absorbing component for cooling. The heat-absorbing component can be made of a phase change material. After absorbing the heat of the handle 103 or the cable 101, the heat-absorbing component can change its form. The heat-absorbing component can be wrapped around the handle 103 and / or the cable 101, or the heat-absorbing component can be arranged to contact one side of the handle 103 and / or the cable 101 to absorb the heat of the handle 103 and / or the cable 101. By absorbing the heat of the handle 103 and / or the cable 101, its temperature is reduced, thereby playing a role in preventing scalding.

[0045] The following is an exemplary description of the charging gun of the embodiment of the present invention through an actual application scenario. The user inserts the charging gun body into the charging port of the electric vehicle to start charging. The temperature sensor detects the temperature at the handle 103 and the cable 101. The display screen 102 displays the temperature of the handle 103 and the cable 101. The temperature of the handle 103 and the cable 101 continues to rise. The temperature of the handle 103 and the cable 101 displayed on the display screen 102 is updated every 5 seconds. When the temperature sensor detects that the temperature of the handle 103 exceeds 50° and / or the temperature of the cable 101 exceeds 60°, the display screen 102 displays a warning message indicating that the temperature is too high, and an alarm prompt sound is emitted through the alarm device to remind the user to pay attention to prevent scalding. At this time, the user needs to unplug the charging gun and stop charging. The user notices the high temperature prompt message and the alarm prompt sound, and knows that the temperature of the handle 103 is too high. Hold the handle 103 across the heat insulation component 104, or use the air cooling component to cool the handle 103 first, unplug the charging gun, and end the charging process.

[0046] The charging gun of the embodiment of the present invention comprises: a charging gun body, a cable connected to the charging gun body, a plurality of temperature sensors and a display screen 102, wherein one of the plurality of temperature sensors is arranged in the handle of the charging gun, and is used to detect the temperature of the handle; another of the plurality of temperature sensors is arranged in the cable, and is used to detect the temperature of the cable; the display screen 102 is used to display a warning message indicating that the temperature is too high when the temperature of the handle and / or the cable exceeds a preset threshold. Thus, by detecting the temperature of the charging gun handle and the cable, and displaying a warning message when the temperature is too high, an anti-scalding reminder is provided, thereby reducing the probability of the user being scalded when operating the charging gun, and improving safety.
