Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a charging pile plug protection mechanism with a mechanical locking function and an implementation method thereof. Background Art

[0002] With the increasing popularity of new energy vehicles, charging stations are being used more and more frequently. During use, the stability and safety of the connection between the charging plug and the charging station socket are crucial. Existing charging station plugs have a weak connection and can easily loosen or even fall off due to external forces, leading to charging interruptions and potential safety hazards. Furthermore, during charging, the internal pressure of the plug may fluctuate due to heat and other factors. Failure to release this pressure in a timely manner can also affect charging safety and device lifespan.

[0003] Therefore, how to provide a charging pile plug protection mechanism with a mechanical locking function and its implementation method to solve the problems existing in the prior art is of great significance to its application. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide a charging pile plug protection mechanism with a mechanical locking function and an implementation method thereof to solve the problem.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A charging pile plug protection mechanism with a mechanical locking function includes a charging gun handle, a charging gun connector, and a charging gun insertion portion. The charging gun handle and the charging gun insertion portion are connected by the charging gun connector. The end of the charging gun insertion portion is provided with a power connection hole, and the charging column is installed in the power connection hole. The top end of the charging gun connector is hinged to a lever, and the end of the lever is provided with a locking buckle and the other end is provided with an unlocking button.

[0007] Furthermore, an exhaust hole is provided inside the charging gun insertion part, and one end of the exhaust hole extends to the end face of the charging gun insertion part; a groove is provided at the top of the charging gun handle, and an airbag is provided in the groove, and the airbag is connected to the other end of the exhaust hole; a one-way valve is installed in the middle of the lever, and the one-way valve is connected to the airbag; a spring is provided inside the airbag; and a sealing rubber gasket is provided on the end face of the charging gun connection part.

[0008] Based on the above structure, the method for implementing the charging pile plug protection mechanism of the present invention includes the following steps:

[0009] S1: The user aligns the charging gun insertion part with the charging pile socket, presses the charging gun handle, and pushes the charging gun insertion part into the socket. During the insertion process, the air inside the charging gun insertion part enters the airbag through the exhaust hole, causing the airbag to inflate;

[0010] S2: Continue to press the handle of the charging gun. When the charging gun insert is fully inserted into the socket, the lever rotates at the hinge at the top of the charging gun connection, so that the locking buckle at the end of the lever snaps into the corresponding slot in the socket, achieving mechanical locking. At this time, the sealing gasket fits tightly against the socket, forming a seal.

[0011] S3: During charging, if the pressure inside the charging gun insertion part changes due to temperature increase, the excess gas can be discharged through the exhaust hole through the airbag and the one-way valve in the middle of the lever;

[0012] S4: After charging is completed, press the unlock button on the other end of the lever. The lever rotates and the locking buckle disengages from the socket slot. At the same time, the spring inside the airbag contracts, pushing the airbag to reset and discharge the gas in the airbag back to the charging gun insertion part through the exhaust hole, making it easier to pull out the charging gun.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention realizes mechanical locking between the charging gun and the charging pile socket by setting a lever and a locking buckle, effectively preventing loosening and falling off caused by external force during charging, and improving the stability of the connection.

[0015] 2. By using the combination of exhaust holes, air bags and one-way valves, excess gas generated in the charging gun insertion part due to temperature increase and other reasons can be discharged in time, avoiding excessive internal pressure, ensuring charging safety and extending the service life of the equipment.

[0016] 3. The setting of the sealing gasket further enhances the sealing of the connection between the charging gun and the socket, preventing the entry of dust, water vapor, etc., and improving the protection performance of the equipment.

[0017] 4. The spring setting enables the airbag to automatically reset after charging is completed, making it easy to pull out the charging gun and the operation is convenient and quick.

[0028] See also Figure 1-2 The present invention provides a technical solution for a charging pile plug protection mechanism with a mechanical locking function and a method for implementing the same:

[0029] A charging pile plug protection mechanism with a mechanical locking function, comprising:

[0030] Charging gun handle 3, charging gun connection part 1 and charging gun insertion part 5;

[0031] The charging gun handle 3 and the charging gun insertion part 5 are connected through the charging gun connection part 1;

[0032] The end of the charging gun insertion part 5 is provided with a power connection hole 6, and a charging column 14 is provided in the power connection hole 6;

[0033] A lever 9 is hinged at the top of the charging gun connection part 1, a locking buckle 8 is provided at the end of the lever 9, and an unlocking button 11 is provided at the other end.

[0034] An exhaust hole 7 is defined inside the charging gun insertion portion 5 , and one end of the exhaust hole 7 extends to the end surface of the charging gun insertion portion 5 .

[0035] A groove 12 is provided at the top of the charging gun handle 3 , and an air bag 15 is provided in the groove 12 . The air bag 15 is connected to the other end of the exhaust hole 7 .

[0036] A one-way valve 10 is installed in the middle of the lever 9 , and the one-way valve 10 is communicated with the air bag 15 .

[0037] A spring 13 is provided inside the airbag 15 .

[0038] The end surface of the charging gun connection part 1 is provided with a sealing rubber pad 2

[0039] During use, the user first aligns the power connection hole 6 of the charging gun insertion part 5 with the corresponding interface of the charging pile socket. Then, holding the charging gun handle 3 and applying pressure, the charging gun insertion part 5 is gradually inserted into the socket. During the insertion process, the air inside the charging gun insertion part 5 is discharged through the exhaust hole 7 provided therein. The exhaust hole 7 is connected to the air bag 15 in the groove 12 of the charging gun handle 3. Therefore, air enters the air bag 15, causing it to expand.

[0040] Once the charging gun's insertion portion 5 is fully inserted into the socket, continue pressing the gun's handle 3. Since the lever 9 is hinged to the top of the charging gun's connection portion 1, the pressure causes the lever 9 to rotate around the hinge. The locking clip 8 at the end of the lever 9 engages the corresponding slot in the socket, mechanically locking the charging gun and the socket. Simultaneously, the sealing gasket 2 on the end of the charging gun's connection portion 1 fits tightly against the socket, creating a strong seal that effectively prevents dust, moisture, and other foreign objects from entering the connection.

[0041] During charging, if the current flowing through the charging gun insert 5 generates heat, causing the temperature to rise and the internal pressure to change, the excess gas can be discharged through the exhaust hole 7, the air bag 15, and the one-way valve 10 installed in the middle of the lever 9. The configuration of the one-way valve 10 ensures that the gas can only be discharged in one direction, preventing external gas from backflowing into the charging gun, thus ensuring the safety and stability of the charging process.

[0042] When charging is complete, the user presses the unlock button 11 on the other end of the lever 9, which pivots the lever 9 about its hinge, releasing the locking clip 8 from the socket and releasing the mechanical lock. At this point, the spring 13 inside the airbag 15, compressed during its expansion, automatically contracts after charging is complete. The contracting force of the spring 13 pushes the airbag 15 back into its original position, and the gas inside the airbag 15 is discharged back into the charging gun insertion portion 5 through the exhaust hole 7, reducing resistance when removing the charging gun and making it easier for the user to remove the charging gun and complete the charging operation.

[0043] The foregoing description is merely a preferred embodiment of the present invention and does not limit the scope of protection of the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any variation, modification, replacement, integration, or parameter change to these embodiments, which is within the spirit and principles of the present invention and which achieves the same functionality through conventional substitutions, without departing from the principles and spirit of the present invention, falls within the scope of protection of the present invention.
