[0030] Example:
[0031] See also Figure 1-3 A new energy vehicle charging head includes a charging gun 1, a handle 2 is fixedly connected to the top of the charging gun 1, and a plug 3 is installed at one end of the charging gun 1, a closing component 4 is arranged on the outside of the plug 3, and the closing component 4 includes an annular block 401, the annular block 401 is sleeved on the outer end of the plug 3, and the annular block 401 is installed on the charging gun 1, and an annular groove 402 is opened at the end of the annular block 401 away from the charging gun 1.
[0032] The existing new energy vehicle charging piles are very simple to use. You only need to remove the charging gun from the charging pile, and then insert the plug at the front of the gun into the charging port of the car to charge. However, when charging outdoors on rainy days, rainwater may enter the charging device through the gap between the plug and the charging port, which may cause a short circuit or electric shock risk to the electrical equipment, and may cause poor contact or corrosion between the plug and the charging port, thereby reducing the charging efficiency. At the same time, poor electrical contact may cause energy loss and current instability, prolonging the charging time and increasing energy consumption.
[0033] In this solution, the user holds the handle 2 and connects the plug 3 at the front end of the charging gun 1 to the charging port on the vehicle. As the plug 3 is inserted into the charging port, the front end of the annular block 401 will abut against the outer shell of the vehicle charging port. The annular block 401 can be made of silicone. Silicone is an elastic material widely used in the manufacture of suction cups. It has good high temperature resistance and chemical corrosion resistance. Therefore, when the annular block 401 abuts against the vehicle shell and is squeezed, the outer end of the annular block 401 and the side walls of the inner circle will deform in opposite directions, thereby compressing the internal space of the annular groove 402. , and squeeze out part of the air in the annular groove 402, so that the inner cavity of the annular groove 402 forms a negative pressure, and the annular block 401 is adsorbed on the surface of the vehicle shell. In this way, the annular block 401 can play a sealing role between the vehicle shell and the charging gun 1, so that the charging port and the plug 3 are in a closed space, and the silica gel itself has good sealing performance, which can minimize the entry of rainwater and achieve a waterproof effect on the plug 3 and the charging port. At the same time, through the adsorption effect of the annular block 401, the stability of the connection between the plug 3 and the charging port can also be enhanced.
[0034] See also Figure 3 The inner cavity of the annular groove 402 is integrally formed with a plurality of support blocks 404 , and the plurality of support blocks 404 are arranged in an annular shape with equal spacing.
[0035] The arrangement of the plurality of support blocks 404 can connect and support the two ends of the inner wall of the annular groove 402 , thereby preventing the annular block 401 from being excessively deformed and causing poor adsorption effect.
[0036] See also Figure 2-3 An exhaust column 403 is integrally formed at the outer end of the annular block 401, and the exhaust column 403 passes through the side wall of the annular block 401, and the inner cavity of the exhaust column 403 is connected to the annular groove 402. The closing component 4 also includes a connecting strip 405, and the connecting strip 405 is installed at the top of the charging gun 1, and a plug 406 is installed at the end of the connecting strip 405 away from the charging gun 1, and the plug 406 matches the inner cavity of the exhaust column 403.
[0037] During the charging process, the plug 406 is inserted into the inner cavity of the exhaust column 403 to seal the exhaust column 403 and prevent external air from entering the annular groove 402 through the exhaust column 403. When the user needs to unplug the charging gun 1, the plug 406 can be pulled out from the exhaust column 403 first, so that the external air can quickly enter the inner cavity of the annular groove 402 through the exhaust column 403, thereby relieving the negative pressure state of the inner cavity of the annular groove 402, causing the annular block 401 to lose its adsorption effect with the vehicle shell, and then the user can easily unplug the charging gun 1. The connecting strip 405 is made of flexible material and is used to connect the plug 406 to prevent it from being lost.
[0038] See also Figure 2-3 A plurality of lamp tubes 6 are installed at one end of the charging gun 1, a through hole 407 matching the lamp tube 6 is opened on the annular block 401, the lamp tube 6 passes through the through hole 407 and extends to the inner cavity of the annular groove 402, a button 5 is installed at the top of the handle 2, and the plurality of lamp tubes 6 are electrically connected to the button 5.
[0039] When charging outdoors at night, it is sometimes difficult to align the plug 3 with the charging port due to dim light. Therefore, the present invention provides a plurality of light tubes 6. When the user holds the handle 2, the user can press the button 5 to make the plurality of light tubes 6 emit light in the direction of the plug 3 for lighting. The plurality of light tubes 6 are arranged in the inner cavity of the annular block 401. The annular block 401 can provide a certain degree of protection for the light tubes 6, thereby reducing the probability of their being damaged by bumps.
[0040] The materials of the annular block 401 and the plurality of supporting blocks 404 are all set to be transparent materials.
[0041] The silica gel itself can be made transparent. By setting the material of the annular block 401 and the plurality of supporting blocks 404 to be transparent, the light of the lamp tube 6 can be better dispersed, thereby improving its lighting effect.
[0042] Working principle:
[0043] When charging, the user holds the handle 2 and connects the plug 3 at the front end of the charging gun 1 with the charging port on the vehicle. As the plug 3 is inserted into the charging port, the front end of the annular block 401 will abut and squeeze the outer shell around the vehicle charging port, and the outer end and inner circle side walls of the annular block 401 will deform in opposite directions, thereby compressing the internal space of the annular groove 402 and squeezing out part of the air in the annular groove 402, so that the inner cavity of the annular groove 402 forms a negative pressure, and the annular block 401 is adsorbed on the surface of the vehicle shell. In this way, the annular block 401 can play a sealing role between the vehicle shell and the charging gun 1, so that the charging port The plug 3 and the charging port are in a closed space, and the silicone itself has good sealing performance, which can minimize the entry of rainwater and achieve a waterproof effect on the plug 3 and the charging port. At the same time, the adsorption effect of the annular block 401 can also enhance the stability of the connection between the plug 3 and the charging port. When the user needs to unplug the charging gun 1, the plug 406 can be pulled out from the exhaust column 403 first, so that the external air can quickly enter the inner cavity of the annular groove 402 through the exhaust column 403, thereby relieving the negative pressure state of the inner cavity of the annular groove 402, so that the annular block 401 loses the adsorption effect with the vehicle shell, and then the user can easily unplug the charging gun 1.
[0044] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
