DETAILED DESCRIPTION

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0026] Embodiment 1:

[0027] See also Figure 1 - Figure 4 In the present embodiment, a charging gun head 1 with a sealing and waterproof structure of the gun head 1 is involved, which is specifically used to prevent rainwater from penetrating into the charging port and the inside of the charging gun head 1 during the charging process of an electric vehicle, and specifically includes: a gun head 1 main body, two protrusions 11 are symmetrically arranged on both sides of the gun head 1, each protrusion 11 is slidably connected to a guide block 2, the guide block 2 is provided with a guide groove 21, the guide groove 21 is slidably adapted to the protrusion 11, a connecting part is provided on the inner side of the guide block 2, the connecting part is connected to the protrusion 11 through a spring 3, a waterproof cover 4 is connected and fixed between the two guide blocks 2, the spring 3 pulls the waterproof cover 4 to cover the top of the gun head 1 shell, and one end of the waterproof cover 4 is connected to the charging port panel 5, and a sealing ring 41 is provided at one end of the waterproof cover 4 and the charging port panel 5.

[0028] Specifically, in this embodiment, see Figure 8, the spring 3 is a tension spring. When the spring 3 is in an unstretched state, the waterproof cover 4 is located at the front side of the gun head 1. In actual operation, when the user inserts the charging gun head 1 into the charging port of the electric vehicle, the waterproof cover 4 is pushed by the charging port panel 5, so that the guide block 2 moves along the guide groove 21 to the side away from the charging port. At this time, the spring 3 is stretched, and the guide block 2 is affected by the restoring tension of the spring 3, so that the sealing ring 41 at one end of the waterproof cover 4 fits tightly around the charging port. Rainwater falls on the waterproof cover 4 and drips along the outside of the waterproof cover 4 under the action of gravity. The connection between the gun head 1 and the charging port is located on the inner side of the waterproof cover 4, so the rainwater cannot fall into the waterproof cover 4, which can effectively prevent rainwater from flowing into the charging port and the charging gun head 1 along the charging gun head 1, avoiding safety hazards such as short circuit of electrical components. The sealing ring 41 in this embodiment is made of high temperature resistant and corrosion resistant rubber material. The sealing ring 41 is deformed when squeezed to cope with various environmental conditions. Through the above structural design, the utility model realizes waterproof protection of the charging gun head 1 in rainy weather environment, improves the safety and reliability of the charging process, and prolongs the service life of the charging gun head 1

[0029] In this embodiment, the waterproof cover 4 adopts an arc-shaped structure, which can effectively guide rainwater to flow along the arc-shaped surface, avoid rainwater accumulation, and prevent rainwater from penetrating into the charging port and the charging gun head 1. A convex edge 42 is provided at one end of the waterproof cover 4. The convex edge 42 expands outward in a trumpet shape and adopts a trumpet-shaped profile. When rainwater splashes onto the surface of the convex edge 42, it immediately flows to the side away from the charging port. The convex edge 42 is made of flexible material. Under the action of the tension of the spring 3, the waterproof cover 4 is always in contact with the charging port panel 5. The convex edge 42 is deformed after being squeezed, which increases its contact area with the charging port panel 5, further preventing the intrusion of rainwater.

[0030] See also Figure 5 In this embodiment, a baffle 12 is provided on the shell of the gun head 1. When the gun head 1 is inserted into the charging port, the waterproof cover 4 is pushed by the charging port panel 5, so that the waterproof plate slides away from the charging port. The end of the waterproof cover 4 away from the charging port is pressed and fitted with the baffle 12, which effectively prevents rainwater from flowing into the gap between the shell and the waterproof cover 4 from the top of the shell. Since a drainage hole is provided at the bottom of the gun head 1 shell, there is no need to set waterproofing at the bottom of the gun head 1, and rainwater can also be drained out from the drainage hole. In addition, in order not to affect the unlocking, the baffle 12 adopts a split structure design, and the middle part 121 thereof is connected to the unlocking key 13 of the gun head 1. During the charging process, the baffle 12 is closed to achieve a waterproof effect. After charging is completed, the user can press the unlocking key 13 to separate the baffle 12, release the fixation of the charging gun head 1, and facilitate the removal of the charging gun head 1.

[0031] See also Figure 6The outer edges of the guide block 2 and its guide groove 21 are obliquely provided with a plurality of guide grooves 22. Rainwater falls on the waterproof cover 4 and flows along the two sides of the waterproof cover 4. The guide grooves 22 guide the rainwater downward to reduce the possibility of rainwater directly impacting the sealing part (the connection between the charging gun head 1 and the charging port). The waterproof cover 4 is a consumable part and needs to be replaced after being damaged. The waterproof cover 4 is connected to the guide block 2 through a snap-fit ​​structure, and the waterproof cover 4 is convenient to replace in a detachable manner.

[0032] Embodiment 2:

[0033] See also Figure 7 and Figure 8 The guide block 2 is rotatably provided with a lock hook 6, and a folded edge 23 is provided on one side of the guide block 2. The lock hook 6 and the folded edge 23 are both provided with magnets 62, and the two magnets 62 attract each other when they are close to each other. When not charging, the lock hook 6 is moved so that the lock hook 6 and the folded edge 23 are mutually attracted through the magnet, so that the hook head of the lock hook 6 is in contact with the outer surface of the folded edge 23 and is clamped. At this time, the waterproof cover 4 is fixed to the front side of the gun head 1 and protects it, effectively avoiding damage caused by accidental drop of the gun head 1.

[0034] The lock hook 6 is provided with an arc-shaped protrusion 61. After charging is completed, since the gun head 1 of the DC charging gun is heavy and it is difficult to pull it out normally, the user first presses the unlocking button 13 of the charging gun head 1 with one hand, and then uses the other hand to respectively move the lock hooks 6 on both sides, so that the arc-shaped protrusion 61 is squeezed toward one side of the charging port panel 5. Under the action of the squeezing force, the gun head 1 is pushed out, thereby realizing the separation of the gun head 1 from the charging port.

[0035] The above contents described in this specification are merely examples of the present utility model. Those skilled in the art of the present utility model may make various modifications or additions to the specific embodiments described, or replace them in similar ways, as long as they do not deviate from the contents of the present utility model specification or exceed the scope defined in the claims, they shall all fall within the protection scope of the present utility model.
