[0002] An electric vehicle charging gun is a device used to charge an electric vehicle. It transfers electrical energy to the battery of the electric vehicle by connecting the power source and the charging interface of the electric vehicle, thereby charging the electric vehicle. Existing electric vehicle charging guns still have certain defects when used.

[0003] In the prior art, electric vehicle charging guns are generally divided into different power and current sizes to meet the charging needs of different models. During outdoor charging, although the charging connector of the charging gun is plugged into the interior of the electric vehicle and is not easy to loosen, there is a certain gap between the charging gun housing and the charging port of the electric vehicle, which causes rainwater to easily flow to the junction of the charging gun housing and the charging port of the electric vehicle, posing a safety hazard when charging the electric vehicle in rainy and snowy weather. Utility Model Content

[0004] The purpose of the utility model is to provide an electric vehicle charging gun to solve the problem of poor waterproof effect of the charging guns currently on the market as mentioned in the background art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electric vehicle charging gun, comprising: a charging gun housing and a charging connector, the end of the charging gun housing is connected to the charging connector, a guide rod is installed inside the charging connector, the outer side of the charging gun housing is injection molded with oblique anti-slip patterns, a connecting block is welded to the outer side of the charging gun housing near the charging connector, and a guide groove is opened inside the connecting block.

[0006] Preferably, a guide block is movably connected inside the guide groove, and ends of two guide blocks are commonly connected to a connecting plate, and a spring is connected between the connecting plate and the connecting block.

[0007] Preferably, a conical rubber sleeve is sleeved on the outer side of the charging gun housing, and a plug-in block is connected to the side of the conical rubber sleeve close to the connecting plate.

[0008] Preferably, the guide blocks are symmetrically arranged in two groups about the center of the connecting plate, and a sliding structure is formed between the guide blocks and the connecting blocks via guide grooves.

[0009] Preferably, a connecting belt is connected to the outer side of the charging gun housing away from the charging connector, and the end of the connecting belt is connected to a storage frame.

[0010] Preferably, a wear-resistant pad is bonded to the inner wall of the storage frame, and a sliding rod is connected to the interior of the storage frame.

[0011] Preferably, a baffle is provided inside the storage frame, a slide groove is penetrated inside the baffle, and a limit knob is penetrated and connected to the inside of the storage frame and the wear-resistant pad.

[0012] Compared with the prior art, the beneficial effect of the utility model is that when the conical rubber sleeve of the electric vehicle charging gun moves, it can drive the plug-in block to move; when the conical rubber sleeve passes through the charging connector and is squeezed and sleeved on the outside of the charging gun housing, the conical rubber sleeve can drive the plug-in block to be inserted into the inside of the connecting plate; at this time, the conical rubber sleeve can be installed on the outside of the charging gun housing; when the limit knob is rotated, its end can be threadedly slid to the surface of the baffle; at this time, the limit knob can squeeze and fix the baffle, thereby storing the power cord on the storage frame, and it is not easy to loosen; the power cord connected to the charging gun housing can be stored through the storage frame, so that when the charging gun is carried or placed, the power cord connected to the charging gun housing is not easy to loosen.

[0013] 1. The charging gun can facilitate personnel to charge electric vehicles, but the waterproof effect of the charging gun is poor. When the conical rubber sleeve moves, it can drive the plug-in block to move. When the conical rubber sleeve passes through the charging connector and is squeezed and sleeved on the outside of the charging gun housing, the conical rubber sleeve can drive the plug-in block to be inserted into the inside of the connecting plate. At this time, the conical rubber sleeve can be installed on the outside of the charging gun housing. When the charging connector is inserted into the charging port of the electric vehicle, the guide rod can play a guiding role. At the same time, the oblique anti-slip pattern can prevent personnel from slipping when plugging and unplugging the charging gun housing, while reducing the plug-in and unplugging force. The operation is smooth. When the charging connector is inserted into the charging port of the electric vehicle, the conical rubber sleeve can be squeezed on the outside of the charging port of the electric vehicle. When the conical rubber sleeve is squeezed, it can squeeze the connecting plate. When the connecting plate is squeezed, the spring can be compressed. The connecting plate can prevent the conical rubber sleeve from producing large deformation. At this time, the end of the charging gun housing and the charging port of the electric vehicle can be protected by the conical rubber sleeve. The conical rubber sleeve can improve the waterproof effect of the charging gun, so that the end of the charging gun housing is tightly connected to the charging port of the electric vehicle, and the conical rubber sleeve has high water resistance and is not easy to be damaged.

[0014] 2. The charging gun is more convenient to carry as a whole. When carrying or placing the charging gun, the power cord connected to the charging gun housing needs to be wound, but the power cord is prone to loosening after winding, affecting the carrying or placement of the charging gun. For this reason, the connecting belt can be tied to the outside of the charging gun housing, and the power cord can be moved to the inside of the storage frame so that the power cord can be placed on the wear-resistant pad. The power cord can fill the storage frame, and at the same time, the power cord inside the storage frame can be squeezed so that the baffle can be moved. When one end of the baffle moves to the maximum distance, the baffle can block the power cord, so that the power cord is not easy to slip out of the storage frame. When the limit knob is rotated, its end can be threaded and slid to the surface of the baffle. At this time, the limit knob can squeeze and fix the baffle, so that the power cord is stored in the storage frame and is not easy to loose. The power cord connected to the charging gun housing can be stored through the storage frame, so that when the charging gun is carried or placed, the power cord connected to the charging gun housing is not easy to loose.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 , Figure 2 and Figure 3It can be seen that the utility model provides a technical solution: an electric vehicle charging gun, comprising: a charging gun housing 1 and a charging connector 2, the end of the charging gun housing 1 is connected to the charging connector 2, a guide rod 3 is installed inside the charging connector 2, the outer side of the charging gun housing 1 is injection molded with an oblique anti-slip pattern 4, a connecting block 5 is welded to the outer side of the charging gun housing 1 near the charging connector 2, a guide groove 6 is opened inside the connecting block 5, and a guide block 7 is movably connected inside the guide groove 6, the ends of the two guide blocks 7 are commonly connected to a connecting plate 8, a spring 9 is connected between the connecting plate 8 and the connecting block 5, a conical rubber sleeve 10 is sleeved on the outer side of the charging gun housing 1, and a plug-in block 11 is connected to the side of the conical rubber sleeve 10 close to the connecting plate 8, two groups of guide blocks 7 are symmetrically arranged about the center of the connecting plate 8, and a sliding structure is formed between the guide block 7 and the connecting block 5 through the guide groove 6.

[0022] During specific implementation, the charging gun can facilitate personnel to charge the electric vehicle, but the waterproof effect of the charging gun is poor. For this reason, the conical rubber sleeve 10 can be pushed. When the conical rubber sleeve 10 moves, it can drive the plug-in block 11 to move. The plug-in block 11 is made of soft rubber. When the conical rubber sleeve 10 passes through the charging connector 2 and is squeezed and sleeved on the outside of the charging gun housing 1, the conical rubber sleeve 10 can drive the plug-in block 11 to be inserted into the inside of the connecting plate 8. At this time, the conical rubber sleeve 10 can be installed on the outside of the charging gun housing 1. When the charging connector 2 is inserted into the charging port of the electric vehicle, the guide rod 3 can play a guiding role. At the same time, the oblique anti-slip pattern 4 can prevent personnel from slipping when plugging and unplugging the charging gun housing 1. The conical rubber sleeve 10 can be squeezed on the outside of the charging port of the electric vehicle, and the conical rubber sleeve 10 is made of silicone. At this time, the conical rubber sleeve 10 will produce extrusion deformation. When the conical rubber sleeve 10 is squeezed, the connecting plate 8 can be squeezed. When the connecting plate 8 is squeezed, the guide block 7 can be driven to move. When the guide block 7 moves, it can slide through the guide groove 6, and when the connecting plate 8 is squeezed, the spring 9 can be compressed. The connecting plate 8 can prevent the conical rubber sleeve 10 from having a large deformation. At this time, the end of the charging gun housing 1 and the charging port of the electric vehicle can be protected by the conical rubber sleeve 10.

[0023] See also Figure 1 , Figure 2 and Figure 3 It can be seen that the conical rubber sleeve 10 can improve the waterproof effect of the charging gun, so that the end of the charging gun housing 1 is more tightly connected to the charging port of the electric vehicle, and the conical rubber sleeve 10 has high water resistance and is not easy to be damaged.

[0024] See also Figure 1 and Figure 4It can be seen that a connecting belt 12 is connected to the outer side of the charging gun housing 1 away from the charging connector 2, a storage frame 13 is connected to the end of the connecting belt 12, a wear-resistant pad 14 is bonded to the inner wall of the storage frame 13, a slide rod 15 is connected to the inside of the storage frame 13, a baffle 16 is provided inside the storage frame 13, a slide groove 17 is penetrated inside the baffle 16, a limit knob 18 is penetrated inside the storage frame 13 and the wear-resistant pad 14, and a sliding structure is formed between the baffle 16 and the slide rod 15 through the slide groove 17.

[0025] In specific implementation, the charging gun is more convenient to carry as a whole. When carrying or placing the charging gun, the power cord connected to the charging gun housing 1 needs to be wound, but the power cord is prone to loosening after winding, which affects the carrying or placement of the charging gun. For this reason, the connecting belt 12 can be tied to the outside of the charging gun housing 1, and the power cord can be moved to the inside of the storage frame 13, so that the power cord can be placed on the wear-resistant pad 14, and the power cord can be continuously wound. After the power cord is wound into a circle, it will be inside the storage frame 13. The power cord can fill the storage frame 13, and the power cord inside the storage frame 13 can be cleaned. The power line is squeezed so that the baffle 16 can move. At this time, the baffle 16 can be pushed. When the baffle 16 moves, it can slide through the slide groove 17 and the slide rod 15. When one end of the baffle 16 moves to the maximum distance, the baffle 16 can block the power line, so that the power line is not easy to slide out from the inside of the storage frame 13. At the same time, the limit knob 18 can be rotated. When the limit knob 18 is rotated, its end can be threadedly slid to the surface of the baffle 16. At this time, the limit knob 18 can squeeze and fix the baffle 16, so that the power line is stored on the storage frame 13 and is not easy to loose.

[0026] See also Figure 1 and Figure 4 It can be seen that the power cord connected to the charging gun housing 1 can be stored through the storage frame 13, so that when the charging gun is carried or placed, the power cord connected to the charging gun housing 1 is not easy to get loose.

[0027] In summary, when using the electric vehicle charging gun, when holding the charging gun housing 1, the end of the charging connector 2 can be inserted into the charging interface of the electric vehicle. At this time, the electric vehicle is charged through the power line connected to the charging gun housing 1. The electric vehicle charging gun is a prior art and will not be described in detail here. The connecting plate 8 can prevent the conical rubber sleeve 10 from being greatly deformed. At this time, the end of the charging gun housing 1 and the charging port of the electric vehicle can be protected by the conical rubber sleeve 10. The conical rubber sleeve 10 can improve the waterproof effect of the charging gun, so that the end of the charging gun housing 1 and the electric vehicle The charging port is connected tightly, and the conical rubber sleeve 10 has high water resistance and is not easy to be damaged. When the limit knob 18 is rotated, its end can be threaded and slid to the surface of the baffle 16. At this time, the limit knob 18 can squeeze and fix the baffle 16, so that the power cord is stored in the storage frame 13 and is not easy to loose. The power cord connected to the charging gun housing 1 can be stored through the storage frame 13, so that when the charging gun is carried or placed, the power cord connected to the charging gun housing 1 is not easy to loose.
