Description

Technical Field

Common new energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc.

[0003] The above-mentioned new energy vehicles need to be replenished in time after the electric energy is consumed. Existing cars will have a charging interface on the body, and a number of charging terminals are set in the charging interface. When charging, the charging gun is connected to the charging terminal, and the electric energy is transmitted to the battery through the charging terminal to charge the battery, so as to ensure that the electric vehicle has a high endurance performance. The charging interface is divided into a fast charging interface and a slow charging interface. Since the battery capacity of pure electric vehicles is large, the owners of such vehicles generally choose fast charging to replenish the car.

[0048] Cars are one of the most popular means of transportation in today's life. They are generally composed of four basic parts: engine, chassis, body and electrical equipment. They have the advantage of facilitating people's travel. In recent years, with the continuous advancement of technology, new energy vehicles have become increasingly popular among the public. Common new energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc.

[0049] The above-mentioned new energy vehicles need to be replenished in time after the electric energy is consumed. Existing cars will have a charging interface on the body, and a number of charging terminals are set in the charging interface. When charging, the charging gun is connected to the charging terminal, and the electric energy is transmitted to the battery through the charging terminal to charge the battery, so as to ensure that the electric vehicle has a high endurance performance. The charging interface is divided into a fast charging interface and a slow charging interface. Since the battery capacity of pure electric vehicles is large, the owners of such vehicles generally choose fast charging to replenish the car.

[0050] According to the electrical parameters of the national standard DC charging interface, the main structure of the fast charging interface is the DC+ and DC- (i.e. positive and negative) terminals. And because the cable between the fast charging pile and the charging gun is thick and bulky, some car owners with less strength insert the charging gun into the charging interface. Although the charging gun and the charging interface are locked, the terminals of the charging gun do not fully contact the terminals of the charging interface, resulting in the failure of the charging pile to start, affecting the normal charging.

[0051] Example 1

[0052] In order to solve the above problems, this embodiment discloses a power connection module for automobile charging, which is arranged on the charging interface, including a module body, a processing module, a positive terminal and a negative terminal installed on the module body, a tension module and a detection module arranged on the module body;

[0053] During charging, the main reason why the charging pile cannot be started is that the terminals of the charging gun and the terminals of the power connection module are in poor contact, which is specifically manifested as insufficient friction between the positive terminal, the negative terminal or one of the terminals in contact with the power connection module and the terminals corresponding to the charging gun. Therefore, in this embodiment, the detection module is used to detect the force value of the positive terminal, the negative terminal or one of the terminals when the charging gun is inserted into the charging interface and contacts the power connection module;

[0054] The tension module is used to apply pressure to the charging gun;

[0055] The processing module is used to receive and analyze the force value obtained by the detection module, and control the tension module to increase or decrease the force applied by the power connection module and the charging gun.

[0056] In this embodiment, the tension module includes a linear push rod connected to the processing module signal and a spring installed at the output end of the linear push rod, and the output end of the linear push rod is opposite to the side wall of the positive terminal or the negative terminal; the processing module controls the extension length of the output end of the linear push rod according to the force value obtained by the detection module.

[0057] After the charging gun is inserted into the charging port, the processing module controls the extension length of the output end of the linear actuator to change the friction between the spring and the charging gun, thereby assisting the charging gun's terminal in fully contacting the power module.

[0058] Please refer to Figure 1 , showing a method for using a power connection module provided by some embodiments of the present application. Figure 1 As shown, it includes the following steps:

[0059] S100. The charging gun is inserted into the charging port of the new energy vehicle, the positive terminal and the negative terminal of the charging gun are respectively in contact with the positive terminal and the negative terminal of the power connection module, and the charging gun and the charging port are locked;

[0060] S200. The detection module obtains the force value of the positive terminal, the negative terminal or one of the positive terminal of the power module;

[0061] S300. The processing module controls the tension module to apply pressure to the charging gun according to the force value of the positive terminal, the negative terminal or one of the two terminals of the power module;

[0062] S400. The processing module controls the force applied to the charging gun by the tension module in real time according to the force value fed back by the detection module;

[0063] S500. Charging is completed, and the processing module controls the tension module to separate from the charging gun.

[0064] Furthermore, in step S200, the calculation formula of the force value obtained by the detection module is:

[0065]

[0066] in, The force value obtained by the detection module, is the sensitivity parameter of the detection module, In this embodiment, the detection module is preferably a force sensor. The force sensor installed at the charging interface can detect the force applied to the charging gun after insertion in real time. The sensor detects the pressure change in the jack and evaluates the tightness of the connection.

[0067] In combination with the second aspect, further, in step S300, the processing module calculates the average force value and force change rate of the positive terminal, the negative terminal or one of them according to the force value obtained by the detection module.

[0068] The calculation formula for the average force value is:

[0069]

[0070] in, is the average force value, is the length of the time period;

[0071] The calculation formula of force change rate is:

[0072]

[0073] in, is the force change rate, is the sampling interval of the detection module.

[0074] In this embodiment, the smaller the force change rate is, the better the tightness between the charging gun and the charging interface is. When the force change rate within a certain unit time period is greater than a certain set threshold, the processing module will start the tension module.

[0075] In combination with the second aspect, further, in step S400, the calculation formula for the force applied by the processing module to the charging gun by the tension module is:

[0076]

[0077] in, is the adjustment factor, is the reference force value.

[0078] The calculation formula for applying force is the same as the feedback adjustment formula, and it is continuously iterated until the force value is stabilized within the reference range.

[0080] In combination with the first aspect, further, the tension module includes a flexible liquid-filling part and a water pump connected to the liquid-filling part and connected to the processing module signal, and the liquid-filling part is embedded in the side wall of the charging interface; the processing module controls the water pump according to the force value obtained by the detection module to circulate liquid into the liquid-filling part and control the flow rate of the liquid.

[0081] In this embodiment, the liquid-filling part is preferably a structure made of silicone material, which acts as a water bag. That is, after the processing module starts the water pump, the water pump continuously introduces liquid into the liquid-filling part, and squeezes the charging gun by hydraulic means, thereby achieving the effect of fastening the charging gun and the charging interface; in addition, since the liquid in the liquid-filling part is continuously flowing, the elastic module of this embodiment can also serve as a cooling device for the charging gun during charging, thereby improving the efficiency of use. Preferably, the number of liquid-filling parts in this embodiment is not less than three, and adjacent liquid-filling parts are connected to form a circulating water circuit with the water pump.
