Description

Technical Field

[0001] The present invention relates to the technical field of preventing a DC liquid-cooled charging gun from jumping and short-circuiting, and in particular to a device with the function of preventing a charging gun from jumping and short-circuiting. Background Art

[0002] As a new energy vehicle, electric vehicles have the advantages of low pollution, low noise, and energy conservation. They can replace traditional vehicles to solve energy shortage and environmental pollution problems. Electric vehicles are increasingly used in life, and the charging equipment such as charging guns used with them are also developing rapidly. Charging can be achieved by connecting the charging gun to the car charging port and the power cord to the external power supply.

[0003] At present, the charging gun used in electric vehicles only realizes the charging function. Since a large current passes through the charging gun when charging, the protection measures of the charging gun interface are very important. At present, the charging gun head of electric vehicles only controls the insertion and removal of the charging gun through an electromagnetic lock when charging. However, due to the working principle of the electromagnetic lock, a pulse signal of 0.03s will be given in the charging pile, and only one lock and unlock command will be given, and no second command will be given. Therefore, in the case of improper operation or external factors, the charging gun cannot be removed from the vehicle. In this case, it is necessary to use a key to manually unlock it (national standard requirement), but because the structure and complexity of the charging guns of each gun company are different, users and even professional maintenance personnel are unable to find the unlocking position, and ultimately the professional Maintenance personnel in the industry can only remove the gun head components, while users will perform destructive treatment on the gun when they are in a hurry, which will cause the charging gun to be damaged and unusable; and some excellent charging pile companies will integrate a separate module in the pile for control. For example, when the gun is locked, click the unlock button on the screen on the pile. This method can effectively solve the problem of locked guns 50%, but due to external factors and human factors, this problem cannot be solved 100%; external factors include electromagnetic locks being damaged when unlocked by external forces, and electromagnetic lock wire cores being burned out when power is supplied for more than 0.05s; human factors: some users will keep pressing the screen unlock button on the pile out of curiosity or fun. When pressing continuously and continuously, the core components in the pile cannot be judged in time, which eventually leads to damage to important components and burning of relays. Summary of the invention

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a device with the function of preventing the charging gun from jumping and short-circuiting, which solves the abnormal locking of the charging gun during use and protects the core electronic components in the charging pile from damage, thereby improving the stability, safety, reliability and other issues of the product and improving the user experience.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a device with the function of preventing a charging gun from jumping and short-circuiting, comprising a circuit device and a structural device, wherein the circuit device comprises an electronic circuit, an integrated program, line control, etc., and the structural device comprises a PCB circuit board, and the circuit board end is fixed inside the charging gun.

[0006] Preferably, the integration of the electronic circuit and the integrated module are connected with the module program in the charging pile after switching.

[0007] Preferably, the charging pile and the charging gun are integrated into one.

[0008] Preferably, the line control performs transit control, reasonable allocation, overcurrent and overload protection.

[0009] Preferably, the operation is performed together with the combined operation of charging piles.

[0010] Preferably, the charging gun controls the working state of the electromagnetic lock by itself, so that it is no longer limited to accepting the execution command of the pulse 0.05s issued by the charging pile, so that the independent module of the charging pile electronic lock used in the charging pile is fundamentally protected.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The present invention effectively avoids the charging guns currently on the market from encountering various usage situations and human operations during the charging process, constantly pressing buttons, and eventually causing the electromagnetic lock core of the charging gun and important electronic components, relays and other parts in the charging pile to burn out, effectively solving these two problems, and subsequent charging guns will not lock the gun and damage important parts such as high-voltage relays in the charging pile.
