New energy electric vehicles are composed of: electric drive and control system, mechanical systems such as drive force transmission, working devices to complete the given tasks, etc. The electric drive and control system is the core of electric vehicles and is also the biggest difference from internal combustion engine vehicles. The electric drive and control system consists of a drive motor, power supply, and motor speed control device. The other devices of electric vehicles are basically the same as those of internal combustion engine vehicles.
[0003] As a green means of transportation with broad development prospects, the national government is also actively promoting the application and development of new energy electric vehicles. Therefore, related facilities and charging connection devices supporting new energy electric vehicles have also emerged. When charging new energy vehicles, the charging gun is mostly plugged into the charging seat of the car to supplement the power supply. Existing car charging guns mostly use terminal connection to achieve charging, but the existing terminals still cannot play a good waterproof role. When there is rain and snow outside, rainwater in the environment can easily enter the charging gun from the power supply terminal, which may cause the charging gun to short-circuit, seriously affecting the safety and service life of the charging gun. To this end, we propose a car charging gun to solve the above problems. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0021] Reference Figure 1-4 A car charging gun comprises a connecting wire 1, a second sealing fixing sleeve 3 and a power connection terminal 14, the right side of the connecting wire 1 is fixedly connected with a first sealing fixing sleeve 2, the left side surface of the second sealing fixing sleeve 3 is fixedly connected with a second charging grab body 4, the left side surface of the second charging grab body 4 is fixedly connected with a second fixing ring 13, and the surface fixing sleeve of the second fixing ring 13 is provided with a first fixing ring 5, the left side of the second sealing fixing sleeve 3 is fixedly connected with the power connection terminal 14, the power connection terminal 14 is inserted into the inside of the first sealing fixing sleeve 2, the inner wall of the second charging grab body 4 is made of rubber material, and during use, due to the particularity of the rubber material itself, under the action of pressure, deformation occurs to fill the gap between the second charging grab body 4 and the first sealing fixing sleeve 2, thereby facilitating the sealing effect.
[0022] Further, see Figure 2 It can be known that holes are symmetrically opened at the upper and lower ends of the first fixed ring 5, and a movable rod 12 is inserted inside the hole. One end of the movable rod 12 inserted inside the first fixed ring 5 is fixedly connected to the limiting ring 7. The movable rod 12 moves inside the hole to push the limiting ring 7 to contact the surface of the first sealing fixed sleeve 2.
[0023] Further, see Figure 4 It can be known that the upper and lower ends of the first fixing ring 5 are symmetrically fixedly connected with an L-shaped bracket 8, and a threaded groove is provided on the surface of the L-shaped bracket 8, and a threaded bolt 10 is inserted inside the threaded groove. The threaded bolt 10 moves up and down inside the threaded groove to facilitate pushing the movable plate 11 to tightly contact the movable rod 12. During use, the self-locking function of the threaded bolt 10 itself can facilitate the fixing and limiting of the movable rod 12.
[0024] Further, see Figure 3 and Figure 4It can be known that a sliding groove is provided on the inner wall of the L-shaped bracket 8, and a fixing rod 9 is inserted inside the sliding groove. A movable plate 11 is sleeved on the surface of the fixing rod 9. The right side of the movable plate 11 contacts the inner wall of the sliding groove, so that it moves up and down. During use, the fixing rod 9 can play a limiting role.
[0025] Further, see Figure 4 It can be known that a return spring 6 is sleeved on the surface of the fixed rod 9, and one end of the return spring 6 is fixedly connected to the movable plate 11, and the other end of the return spring 6 is fixedly connected to the outer wall of the first fixed ring 5. During use, the elastic deformation of the return spring 6 itself facilitates the reset of the limit ring 7.
[0026] Further, see Figure 3 It can be known that two groups of limit rings 7 are provided, and the two groups of limit rings 7 are arc-shaped structures. The limit rings 7 are in conflict with the outer wall of the first sealing fixing sleeve 2. The limit rings 7 are made of a highly elastic polymer material with reversible deformation. They are elastic at room temperature and can produce larger deformations under very small external forces. They can return to their original shape after the external forces are removed.
[0027] Further, see Figure 3 and Figure 4 It can be known that according to the attached Figure 1 , Attachment Figure 2 , attached Figure 3 and attached Figure 4 As shown, when charging is required, the power connection end 14 is inserted into the interior of the first sealing fixing sleeve 2, and the limiting ring 7 is in conflict with the surface of the first sealing fixing sleeve 2. During the installation process, the outer wall of the first sealing fixing sleeve 2 is tightly fitted with the interior of the second charging grab body 4, which can achieve a good sealing effect. After the connection is completed, the operator manually rotates the threaded bolt 10, and the threaded bolt 10 moves to push the movable rod 12 to move. The movable rod 12 moves to push the limiting ring 7 to tightly contact the surface of the first sealing fixing sleeve 2, thereby achieving the effect of fixed limiting. The operation is completed. The above is the entire working principle of the utility model.
