The slide rail 7 is adapted to the slide groove 23. The two sides and the upper side of the installation cavity are provided with cable holes. The connecting wires of the gun head and the plug cable 4 extend through the cable holes. Similarly, the two sides and the upper side of the front cover 21 are provided with corresponding cable holes.

[0058] Four positioning tubes 24 are limitedly provided inside the front cover 21 and the rear cover 22 .

[0059] The locking member 8 includes three fixed blocks 81, and the three fixed blocks 81 are all fixed to the top of the inner wall of the installation cavity. Both sides of the three fixed blocks 81 are fixedly connected with sliding rods 82, and the surface of the sliding rods 82 is slidably connected with locking shafts 83, and adjacent locking shafts 83 are fixedly connected by connecting arms.

[0060] Three positioning sleeves 25 are respectively provided inside the corresponding front cover 21 and rear cover 22 , wherein a cylindrical groove is formed at one end of the locking shaft 83 located in the middle.

[0061] The bottom of the fixed block 81 located in the middle is fixedly connected to a connecting shaft 84, the locking shaft 83 located in the middle is sleeved on the surface of the connecting shaft 84, the surface of the connecting shaft 84 is fixedly connected to a retaining ring, and an elastic member 85 is sleeved on the surface of the connecting shaft 84 and located between the retaining ring and the locking shaft 83.

[0064] The operating handle 63 includes a main board part and a connecting ring part. The operating handle 63 is made of metal that can be adsorbed by a magnet. The diameter of the pushing block is larger than the pushing shaft 62. Sealing strips are bonded to the sides of the front cover shell 21 and the rear cover shell 22. A sealing groove is provided on the inner surface of the corresponding installation cavity to improve the sealing of the connection.

[0065] The working principle of the integrated European standard charging gun for new energy electric vehicles provided by the present invention is as follows:

[0066] When the circuit board of the charging gun needs to be repaired, the operating handle 64 inside the groove 61 on the front and rear sides of the detachable part 2 is rotated outwards, and then the index finger and thumb can be inserted into the connecting ring at the end of the operating handle 64, and then the pushing shaft 62 is pushed at the same time. The pushing shaft 62 pushes the pushing block at the end, and the pushing block pushes the locking shaft 83 in the middle out of the positioning sleeve 25 inside the front cover 21 and the rear cover 22, and at the same time drives the other two locking shafts 83 to move out of the positioning sleeve 25 through the connecting arm;

[0067] At this time, the entire detachable portion 2 can be slid downward, and then the front cover 21 and the rear cover 22 can be separated to inspect the internal circuit board;

[0068] During installation, the positioning shafts 11 on both sides of the circuit board 10 are correspondingly inserted into the positioning tubes 24 on the front cover 21 and the rear cover 22 to position the circuit board. Then, the connecting wires on the circuit board can be extended through the holes on both sides and the top of the front cover 21 to electrically connect with the charging head, plug cable and switch. After the connection, the excess length of the wire can be stored inside the removable part 2.

[0069] Then slide the slide grooves 23 on both sides of the front cover shell 21 and the rear cover shell 22 into the slide rails 7 on both sides of the corresponding installation cavity. When it moves up, the positioning sleeve 25 contacts the arc surface at the bottom of the locking shaft 83. At this time, the positioning sleeve 25 squeezes the locking shaft 83 to make it slide inward along the slide rod 82 and compress the elastic member 85. When the detachable part 2 is fully inserted, the locking shaft 83 corresponds to the positioning sleeve 25. The elastic member 85 pushes the locking shaft 83 into the interior of the positioning sleeve 25 to fix it. The operation is simple and convenient.

[0070] Compared with related technologies, the integrated European standard charging gun for new energy electric vehicles provided by the present invention has the following beneficial effects:

[0071] By setting up the detachable part 2, the detachable part 2 is stably installed through the locking part 8, the positioning sleeve 25, and the slide groove 23 and the slide rail 7, and the operation is simple. The slide grooves 23 on both sides of the detachable part 2 are slid into the mechanism corresponding to the slide rail 7. When disassembling, the detachable part can be removed by rotating and pressing the operating handle 63. At the same time, the front cover 21 and the rear cover 22 can be directly opened, which is convenient for disassembly and installation of the internal circuit board, and also convenient for inspection and maintenance of the circuit board.

[0072] Second embodiment

[0073] Please refer to Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12 Based on the new energy electric vehicle integrated European standard charging gun provided in the first embodiment of this application, the second embodiment of this application proposes another new energy electric vehicle integrated European standard charging gun.

[0074] Specifically, the difference of the integrated European standard charging gun for new energy electric vehicles provided in the second embodiment of the present application is that, the integrated European standard charging gun for new energy electric vehicles, the interior of the detachable part 2 is equipped with an air-cooling drive mechanism 12, and the air-cooling drive mechanism 12 includes a three-way pipe 121, and the three-way pipe 121 is installed inside the rear cover 22 and is located on the rear side of the circuit board 10. Both ends of the three-way pipe 121 are connected to connecting pipes 122, and the two connecting pipes 122 are Z-shaped pipes arranged in opposite directions. One end of the two connecting pipes 122 is connected to a connecting part 123, and one side of the connecting part 123 is connected to an exhaust plate 124.

[0075] The outer end of the tee pipe 121 is connected to the gas pipe, one end of which is connected to a blower. The blower is installed indoors or underground according to the use environment, and the installation location can be equipped with a refrigeration mechanism, such as an air conditioner. The gas pipe is buried underground, and the outer end is connected to the wire connected to the charging plug through a buckle.

[0076] The two connecting pipes 122 are Z-shaped pipes and are connected in reverse, that is, the two exhaust plates 124 are as shown in the attached Figure 8 It is arranged up and down, that is, the two exhaust plates 124 blow the airflow through the upper and lower sides of one side of the circuit board, so that the airflow can act more evenly on the side of the circuit board where the electrical components are arranged. The connecting pipe 122 is fixedly connected to the rear cover 22 through a connecting piece.

[0077] A plurality of strip-shaped holes 125 are formed on the inner side of the exhaust plate 124 , and a rectangular hole 126 is formed on the inner side of the exhaust plate 124 and on one side of the strip-shaped holes 125 .

[0078] The width of the slot cavity of the strip hole 125 is much smaller than that of the rectangular hole 126, and the strip hole 125 is close to one side of the circuit board 10, so that the airflow flowing to the circuit board 10 can be slowed down, so that the airflow can be smoothly replaced and contacted with the circuit board 10. The airflow discharged through the rectangular hole 126 is faster and has a greater wind pressure, and the rectangular hole 126 corresponds to the position of the driving impeller 133.

[0079] An adjusting mechanism 13 is installed on the front side of the front cover 21. The adjusting mechanism 13 includes a mounting cover 131. An air outlet 135 is provided on the front side of the mounting cover 131. A driving shaft 132 is rotatably connected to the mounting cover 131. The driving shaft 132 is located outside the mounting cover 131 and is fixedly connected to a driving impeller 133 inside the front cover 21.

[0080] The air outlet 135 is a circular hole, and the mounting cover 131 is embedded in the front cover shell 21. The air outlet 135 is connected to the external environment. The driving impeller 133, the circular sealing plate 136 and the telescopic rod 134 are all made of lightweight plastic material, and a sealing ring is bonded to the inner side of the circular sealing plate 136.

[0081] The driving shaft 132 is located inside the mounting cover 131 and is fixedly connected to a telescopic rod 134 . A pushing bar 139 is fixedly connected to the output shaft of the telescopic rod 134 .

[0082] The telescopic rod 134 includes an outer tube, a piston block is provided inside the outer tube, a piston rod is fixed to one side of the piston block, and one end of the piston rod passes through the outer tube. The mass of the pushing block is heavier than the mass of the piston rod.

[0083] A circular sealing plate 136 is provided inside the mounting cover 131 at a position corresponding to the air outlet 135 . A flange is provided on the inner edge of the circular sealing plate 136 . The inner side of the flange contacts the push bar 139 . An adsorption ring 137 is embedded inside the flange.

[0084] The adsorption ring 137 is made of metal that can be adsorbed by a magnet.

[0085] An electromagnet 138 is installed on one side of the inner wall of the installation cover 131 .

[0086] The electromagnet 138 is powered by a battery, which is preferably a rechargeable battery.

[0087] When the charging gun is in use, after the switch is turned on, the switch simultaneously controls the electromagnet 138 to be de-energized and loses its magnetism;

[0088] The airflow enters the two connecting pipes 122 through the three-way pipe 121 and is discharged through the two exhaust plates 124. The airflow generated by the two exhaust plates 124 acts on the side of the circuit board 10 where the electrical components are provided from the upper and lower sides. At the same time, the two airflows act on the driving impeller 133 from the upper and lower sides and from two directions, thereby driving the driving impeller 133 to rotate, driving the impeller 133 to rotate, thereby driving the driving shaft 132 to rotate, and driving the driving shaft 132 to drive the telescopic rod 134 to rotate. Due to the centrifugal force generated by the rotation, the piston rod in the telescopic rod 134 extends outward, and because the electromagnet 138 is currently in a power-off state, the piston rod pushes the pushing bar 139 to push the flange part of the circular sealing plate 136, so that the position of the flange part and the air outlet 135 are continuously staggered, so that the air pressure inside the detachable part 2 can be discharged and dissipated through the part staggered between the circular sealing plate 136 and the air outlet 135;

[0089] When use is finished, the air flow stops and the switch controls the electromagnet 138 to be energized. At this time, the electromagnet 138 adsorbs the adsorption ring 137 to return the circular sealing plate 138 to its original position, sealing the air outlet 135 to prevent dust and other foreign matter from entering.

[0090] By setting up an air-cooling drive mechanism 12, the internal heat dissipation effect of the charging gun can be improved when it is working. At the same time, the incoming air flow is coordinated with the adjustment mechanism to stagger the circular sealing plate 136 and the air outlet 135, thereby exhausting. When charging is completed, the air flow stops, and the circular sealing plate 136 can seal the air outlet 135 to prevent dust and other foreign matter from entering, making it easy to use.

[0091] Third embodiment

[0092] Please refer to Figure 13 Based on the new energy electric vehicle integrated European standard charging gun provided in the first embodiment of this application, the third embodiment of this application proposes another new energy electric vehicle integrated European standard charging gun.

[0093] Specifically, the difference of the integrated European standard charging gun for new energy electric vehicles provided in the second embodiment of the present application is that one end of the three-way pipe 121 is connected to a connector 14, wherein one end of the gas pipe 9 for gas transmission is provided with an adaptive fixing head 15;

[0094] The connector 14 includes a fixed tube 141, an internally threaded tube 142 being rotatably connected to the outer side of the fixed tube 141, a sealing plate 143 being rotatably connected to the inner side of the lower portion of the sealing plate 143, a second magnetic block 144 being fixedly connected to the inner side of the lower portion of the sealing plate 143, and a stopper 145 being fixedly connected to the lower side of the inner wall of the fixed tube 141 and located inside the sealing plate 143, a receiving groove being formed on the stopper 145, the receiving groove and the second magnetic block 144 being clearance-fitted, and the stopper 145 being made of metal that can be attracted by a magnet;

[0095] The interior of the fixed head 15 is fixedly connected to a push rod, and the surface of the fixed head 15 is provided with an external thread;

[0096] During installation, the external thread on the outer surface of the fixing head 15 is threadedly connected to the internal threaded tube 142 on the fixing tube 141. During the connection process, the push rod 16 pushes the upper side of the sealing plate 143 to rotate it 90 degrees. At this time, the fixing tube 141 is connected to the inside of the fixing head 15, thereby realizing the function of gas transmission.

[0097] When cooling is not required in cold weather, the fixing head 15 can be unscrewed. After unscrewing, the push rod 16 no longer limits the sealing plate 143. At this time, since the second magnetic block 144 is provided on the lower side of the sealing plate 143, that is, the lower side ends at the upper side, the sealing plate 143 automatically rotates downward due to gravity. When the second magnetic block 144 contacts the stopper 145, the second magnetic block 144 and the stopper 145 are attracted and located inside the receiving slot to limit the position.

[0098] That is, after disassembly, the sealing plate 143 can automatically seal the fixed tube 141 to prevent external dust and the like from entering the interior of the detachable part 2, making it easy to use.

[0099] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
