TECHNICAL FIELD

[0001] The present application belongs to the technical field of new energy vehicle charging, and particularly relates to a rainproof charging device for new energy vehicles and a use method. BACKGROUND

[0002] The statements in this section merely provide background information related to the present application and do not necessarily constitute the prior art.

[0003] The charging place of an electric vehicle is mostly located in an outdoor open scene, which has a very high requirement for the rainproof performance of the charging device. Since the vehicle itself is not provided with a charging port rainproof device, the intrusion of rainwater into the charging device when the vehicle is charging will cause unstable charging voltage, which is very harmful to the battery and the vehicle circuit, and also threatens the personal safety of the vehicle owner.

[0004] The waterproof treatment of the vehicle charging interface is mostly in a passive form, such as using hydrophobic materials, corrosion-resistant materials, and sealed waterproof structure design, which has a high cost and cannot fundamentally prevent the intrusion of rainwater, but only can be passively protected.

[0005] Currently, disposable rain covers and other devices are usually used for temporary protection, but since they are generally used by pasting, the problem of unstable pasting and falling is prone to occur. SUMMARY

[0006] In order to overcome the shortcomings of the prior art, the present application provides a rainproof charging device for new energy vehicles and a use method.

[0010] The inner side of the dust cover is provided with a rainwater sensor, and the gas delivery pipe inside the rain shelter is provided with a pressure sensor; when the dust cover is opened, the controller controls the inflation assembly to inflate the rain shelter according to the signals collected by the rainwater sensor and the pressure sensor, so that the rain shelter protrudes from the vehicle body to shield the charging interface.

[0011] The second aspect of the present application provides a use method of the rainproof charging device for new energy vehicles, based on the rainproof charging device for new energy vehicles provided in the first aspect of the present application, comprising:

[0012] The dust cover of the charging interface on the vehicle is opened, and the rainwater sensor arranged on the inner side of the dust cover starts to collect rainwater signals; the pressure sensor arranged in the gas inlet pipe in the rain shielding part collects pressure signals in the rain shielding part;

[0013] The controller judges whether to inflate and / or deflate the rain shielding part according to the signals collected by the rainwater sensor and the pressure sensor, and when the rain shielding part is fully inflated, it protrudes from the vehicle body to shield the charging interface from rain.

[0014] The above one or more technical solutions have the following beneficial effects:

[0015] The rainproof charging device provided by the present application can protrude from the vehicle body to shield the charging interface from rain when charging the new energy vehicle in rainy days, solving the problem of poor protection effect of disposable rain cloth when charging the vehicle in rainy days, improving the safety of the new energy vehicle when charging in rainy days, and being low in cost and convenient to use.

[0021] The present application will be further described below in combination with the drawings and embodiments.

[0022] Embodiment 1

[0023] As Figure 1As shown, the application provides a rainproof charging device for new energy vehicles, comprising: a charging interface 3 embedded on the vehicle and a dustproof cover 1 rotatably opened on the charging interface 3;

[0024] A groove for accommodating the rain cover 4 is arranged at the upper edge of the charging interface 3, the rain cover 4 is a flat airbag structure with an inflation opening at one end made of a relatively solid elastic material, and the opening end of the rain cover 4 is connected to the inflation assembly through a gas delivery pipe;

[0025] A rain sensor 2 is arranged on the inner side of the dustproof cover 1, and a pressure sensor 5 is arranged on the gas delivery pipe inside the rain cover 4, and the controller controls the inflation assembly to inflate the rain cover 4 according to the signals collected by the rain sensor 2 and the pressure sensor 5, so that the rain cover 4 protrudes from the outer wall 7 of the vehicle body to shield the charging interface.

[0026] In some embodiments of the application, the inflation assembly is built in the vehicle body and is equipped before the vehicle is delivered; or the inflation assembly and the charging interface are integrated together, which can be replaced by replacing the charging interface, and the airbag can also be replaced separately.

[0027] In some embodiments of the application, the rain cover is made of a relatively hard inflatable elastic material, and after inflation, it has a solid structure similar to a safety airbag due to the large inflation pressure;

[0028] The rain cover is in a flat brim structure after being filled with gas inside, which is located above the vehicle charging interface and protrudes from the outer wall of the vehicle body to shield the vehicle charging interface from rain.

[0029] In addition, a water blocking part is additionally arranged above the end of the rain cover close to the vehicle charging interface, and the water blocking part and the rain cover are integrally formed and are both airbag structures made of elastic material;

[0030] The water blocking part communicates with the rain cover and is arranged along the upper surface of the rain cover, and the water blocking part protrudes from the rain cover after inflation, and is used to guide the rainwater on the surface of the rain cover to prevent the rainwater on the surface of the rain cover from flowing into the mounting groove of the rain cover.

[0031] The rain sensor 2 is installed on the inner side of the dustproof cover 1, and under the condition that the dustproof cover 1 is not opened, the rain sensor 2 does not detect the rain signal; only under the condition that the dustproof cover 1 is opened during charging, the rain sensor 2 can monitor the rain signal and transmit the signal data to the controller.

[0032] The pressure sensor 5 is arranged on the gas conveying pipe inside the rain cover 4, the connection between the gas conveying pipe and the rain cover 4 is a sealed structure, and the length of the gas conveying pipe inside the rain cover 4 is short, which is not greater than the width of the groove, so as to facilitate the folding storage of the rain cover. The pressure sensor 5 is used for detecting the gas pressure value inside the rain cover 4 and transmitting to the controller.

[0033] In some embodiments of the application, the charging interface is a double socket charging interface integrated with a high-voltage charging interface and a low-voltage charging interface; the groove for accommodating the rain cover 4 is opened above the high-voltage charging interface and the low-voltage charging interface, one end of the rain cover 4 provided with an inflation port is fixed in the groove, and the movable end of the rain cover 4 can be wound or folded and stored in the groove on the charging interface after deflation; the rain cover 4 can cover the upper and both sides of the charging interface 3 after being fully inflated.

[0034] The rain cover 4 can cover the both sides of the charging interface 3 in the inflated state, and completely covers the contact position of the charging interface 3 and the charging plug, realizing a larger rain cover area.

[0035] In some embodiments of the application, the inflation assembly includes a micro air pump and a one-way valve, the micro air pump is connected with the gas conveying pipe, and the one-way valve is arranged on the gas conveying pipe to ensure that the gas provided by the micro air pump flows to the inside of the rain cover in one direction.

[0036] Specifically, the micro air pump is installed at the back of the end surface of the charging interface and connected with the air bag through the gas conveying pipe; the middle part of the gas conveying pipe is provided with a one-way valve to ensure one-way flow of the gas and realize inflation of the air bag.

[0037] In some embodiments of the application, the rain cover 4 is provided with a normally open valve 6, and the normally open valve 6 is electrically connected with the controller; the normally open valve 6 is in a normally open state, and the controller controls the opening and closing of the normally open valve and the inflation assembly according to the signals collected by the rain sensor 2 and the pressure sensor 5.

[0038] By arranging the normally open control valve 6 on the rain cover 4, it is ensured that the rain cover 4 is in a deflated state in normal times, when the rain sensor 2 receives a rain signal, the micro air pump starts to work, and the normally open valve 6 is closed to realize inflation.

[0039] In some embodiments of the application, when the rain sensor 2 continuously detects a rain signal within a set time and the pressure value detected by the pressure sensor 5 is less than a set value, the inflation assembly is opened, and the normally open valve is closed to realize inflation of the rain cover.

[0040] Specifically: when the rain sensor 2 continuously detects the rain signal within the set time, and the pressure value detected by the pressure sensor 5 is greater than and / or equal to the first set value, the inflation assembly is closed, and the normally open valve 6 remains closed to achieve the rainproof state of the inflated rain cover;

[0041] When the rain sensor 2 does not detect the rain signal within the set time, and the pressure value detected by the pressure sensor 5 is greater than and / or equal to the first set value, the inflation assembly is closed, and the normally open valve 6 is opened to deflate the inflated rain cover.

[0042] When the rain sensor 2 does not detect the rain signal within the set time, and the pressure value detected by the pressure sensor 5 is less than the second set value, the inflation assembly is closed, and the normally open valve remains open.

[0043] The control module is composed of a signal acquisition device, a processor, and a signal output device. The signal acquisition device receives signals transmitted by the rain sensor and the pressure sensor and transmits them to the processor. The processor processes the received signals and sends instructions to each component through the signal output device.

[0044] When the dust cover is opened and the electric vehicle starts charging, the signal acquisition device starts receiving the rain signal of the rain sensor and transmits it to the processor. If it is raining, the processor activates the inflation assembly and the rain cover through the signal output device.

[0045] That is, first, close the normally open control valve on the rain cover, and the signal acquisition device further receives the signal of the pressure sensor and transmits it to the processor. If the pressure is lower than the first set value 1.3 bar, output the control signal to open the micro-pump, and the micro-pump delivers gas to the rain cover through the gas pipe. When the total pressure in the rain cover is higher than the first set value 1.3 bar, the micro-pump stops working, and the inflation of the rain cover is completed. When the rain stops, the normally open control valve is controlled to return to the normally open state, the rain cover is deflated, and the entire device returns to the initial state.

[0046] Preferably, the duration is set to 15s, and if no rain signal is detected within the set time, the entire device stops working. When it is still raining outside, but the rain cover needs to be closed after charging is completed, the rain sensor can be manually wiped and temporarily shielded, so that the rain cover can be deflated and returned to the initial state without detection of rain by the rain sensor.

[0047] Preferably, the rain cover is fixed at a 90° position on both sides of the charging interface, ensuring that the rain cover is fully inflated and can fully shield the rain.

[0048] Example Two

[0049] As Figure 2 shown, the application provides a method for using a rainproof charging device for new energy vehicles, based on a rainproof charging device for new energy vehicles provided in Embodiment One, which comprises:

[0050] opening the dust cover of the charging interface on the vehicle, the rainwater sensor arranged inside the dust cover starts collecting rainwater signals; the pressure sensor arranged inside the rain-shielding part collects pressure signals inside the rain-shielding part;

[0051] the controller determines whether to inflate and / or deflate the rain-shielding part according to the signals collected by the rainwater sensor and the pressure sensor, and when the rain-shielding part is fully inflated, it protrudes from the vehicle body to shield the charging interface.

[0052] The edge of the charging interface is provided with a groove for accommodating the rain-shielding part, and the rain-shielding part is a gas bag structure with an open end made of relatively solid elastic material. The open end of the rain-shielding part is connected to the inflation assembly through an air pipe.

[0053] The controller determines whether to inflate and / or deflate the rain-shielding part according to the signals collected by the rainwater sensor and the pressure sensor, comprising:

[0054] When the rainwater sensor continuously detects rainwater signals within a set time, and the pressure value detected by the pressure sensor is less than a set value, the inflation assembly is turned on, and the normally open valve is closed to inflate the rain-shielding part;

[0055] When the rainwater sensor continuously detects rainwater signals within a set time, and the pressure value detected by the pressure sensor is greater than and / or equal to a first set value, the inflation assembly is turned off, and the normally open valve remains closed to keep the inflated rain-shielding part in a rainproof state;

[0056] When the rainwater sensor does not detect rainwater signals within a set time, and the pressure value detected by the pressure sensor is greater than and / or equal to a first set value, the inflation assembly is turned off, and the normally open valve is opened to deflate the inflated rain-shielding part;

[0057] When the rainwater sensor does not detect rainwater signals within a set time, the inflation assembly is turned off, and the normally open valve remains open.

[0058] In some embodiments of the application, when the charging is completed, the rain has not stopped. Since the rain cover is in an inflated state, the dust cover cannot be closed directly. After the charging plug is pulled out, the rain sensor can be manually blocked for about 10s. If the signal acquisition device does not receive a rain signal for 10s, the processor will default that the rain has stopped, the signal output device will output a signal to restore the normally open state of the normally open control valve on the rain cover, deflate the rain cover, manually restore the rain cover to the outer wall of the vehicle body around the charging interface, and then close the waterproof dust cover.

[0059] When the rain stops and the charging of the vehicle is not completed, if the rain sensor does not receive a rain signal for 10s, the entire control system will also adjust as described above to deflate the rain cover. After the charging is completed, the rain cover only needs to be manually restored to the groove to close the waterproof dust cover.

[0060] Although the specific embodiments of the application are described above with reference to the accompanying drawings, the description is not a limitation on the scope of protection of the application. Those skilled in the art should understand that various modifications or variations made on the basis of the technical solutions of the application without creative labor are still within the scope of protection of the application.
