Description

Technical Field

[0001] The utility model belongs to the technical field of electric vehicle charging ports, and more specifically, particularly relates to a sealing structure of an electric vehicle charging port. Background Art

[0002] Electric vehicle charging ports are mainly used in new energy vehicles. Electric vehicles can be charged by using charging piles and charging ports in conjunction. However, traditional electric vehicle charging ports only rely on a cover plate. After charging is completed, the charging port is covered to isolate the charging port from the outside world. However, the cover plate has poor sealing performance. On rainy days, rainwater may flow into the charging port through the gap between the cover plate and the charging port, causing a short circuit when the charging port is charging, seriously affecting the charging safety of the car owner and may even cause a fire.

[0003] The existing publication number CN219600936U discloses a sealing structure for an electric vehicle charging port. Although the two sealing plates are abutted against the upper side wall of the charging cavity, and the two sealing plates are abutted against each other, the charging cavity is completely blocked to prevent rainwater from flowing into the charging cavity through the gap. When the car owner needs to charge, he only needs to insert the charging gun into the socket, and the two sealing plates will fold outwards towards each other, thereby driving the sliding ring to overcome the elastic force of the reset spring and move downward, thereby improving the convenience of the car owner when charging.

[0004] Based on the above, the inventors have discovered the following problems: the sealing structure is relatively complex and uses the elastic force of the spring to work. When the spring is in a certain state for a long time, it will affect the elasticity of the spring, causing the device to fail to work properly. When the spring elastic force is insufficient, the sealing plate will become difficult to flip. At the same time, the sealing device does not have the function of limiting the charging gun. During charging, the sealing device may be sealed, but the charging gun may not be tightly connected.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a sealing structure for the charging port of an electric vehicle is provided, in order to achieve a purpose with greater practical value. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a sealing structure for an electric vehicle charging port to solve the problem that the elasticity of the spring will be affected after being in a certain state for a long time, causing the device to fail to work normally and the sealing device may be sealed but the charging gun is not tightly connected.

[0007] The utility model provides a sealing structure for a charging port of an electric vehicle, which is achieved by the following specific technical means:

[0008] A sealing structure for a charging port of an electric vehicle is applied to a charging gun, wherein a charging wire is fixed at one end of the charging gun, a clamping ring is fixed at the middle of an outer wall of the charging gun, a sliding rod is movably installed through the middle of the clamping ring, a moving ring is fixed at one end of the sliding rod, a connecting ring is fixed at the other end of the sliding rod, a handle is fixed at the bottom of the connecting ring, a clamping block is fixed at the bottom of the handle, a connecting block is fixed at the bottom of the charging wire, a buckle is fixed at one end of the connecting block, a first connecting rod is movably installed on the outer wall of the moving ring, a second connecting rod is movably installed on the outer wall of the charging gun, and an elastic sealing ring is fixed at one end of the first connecting rod.

[0009] Furthermore, the clamping block and the clamping buckle are located in the same horizontal plane, and the clamping block and the clamping buckle are used in combination.

A second hinge seat is fixed on the outer wall of the charging gun, and the second hinge seat is rotatably connected to one end of the second connecting rod.

[0011] Furthermore, a connecting groove is provided through the middle of the first connecting rod, the top end of the second connecting rod is located inside the connecting groove and is rotatably connected to the first connecting rod, and multiple first connecting rods and connecting grooves are provided, and the multiple first connecting rods and connecting grooves are arranged equidistantly around the circumference.

[0012] Furthermore, the outer wall diameter value of the clamping ring is greater than the outer wall diameter value of the moving ring, and the outer wall diameter value of the elastic sealing ring is greater than the outer wall diameter value of the clamping ring.

[0013] Furthermore, a sliding groove is penetrated through one side of the clamping ring, and the sliding rod is slidably connected to the sliding groove. A plurality of sliding rods are provided, and the plurality of sliding rods are arranged equidistantly around the circumference.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. In the utility model, the movable ring is driven to move toward the side of the charging wire by pulling the handle, and the spacing between the first hinge seat and the second hinge seat becomes smaller, driving the angle between the first connecting rod and the second connecting rod to become smaller, so that the ends of the multiple first connecting rods close to the charging wire expand outward at the same time, and the elastic sealing ring expands together until it stretches to a horizontal state and fits with one side of the clamping ring for sealing. Fewer parts are needed, thereby achieving the effect of simple device structure and longer service life.

[0016] 2. In the utility model, the clamping ring is clamped with the charging port of the car, and when the handle is pulled outward, the elastic sealing ring expands together until it stretches to a horizontal state. At this time, the clamping block and the buckle are connected, and the elastic sealing ring expands to block the gap between the clamping ring and the charging port of the car from the inside, thereby achieving sealing from the inside, which can ensure that the charging gun is sealed after being tightly connected, thereby increasing the safety of use.

[0027] The utility model provides a sealing structure for a charging port of an electric vehicle, which is applied to a charging gun 1, wherein a charging wire 2 is fixed at one end of the charging gun 1, a clamping ring 3 is fixed at the middle of an outer wall of the charging gun 1, a sliding rod 5 is movably installed through the middle of the clamping ring 3, a moving ring 6 is fixed at one end of the sliding rod 5, a connecting ring 7 is fixed at the other end of the sliding rod 5, a handle 8 is fixed at the bottom of the connecting ring 7, a clamping block 9 is fixed at the bottom of the handle 8, a connecting block 10 is fixed at the bottom of the charging wire 2, a buckle 11 is fixed at one end of the connecting block 10, a first connecting rod 13 is movably installed on the outer wall of the moving ring 6, a second connecting rod 15 is movably installed on the outer wall of the charging gun 1, and an elastic sealing ring 17 is fixed at one end of the first connecting rod 13.

[0028] The block 9 and the buckle 11 are located in the same horizontal plane, and the block 9 and the buckle 11 are used in combination. By inserting the block 9 into the buckle 11, the block 9 is limited, and then the adjusted first connecting rod 13 and the second connecting rod 15 are limited.

[0029] Among them, a first hinge seat 12 is fixed on the outer wall of the movable ring 6, and the first hinge seat 12 is rotatably connected to one end of the first connecting rod 13. A second hinge seat 16 is fixed on the outer wall of the charging gun 1, and the second hinge seat 16 is rotatably connected to one end of the second connecting rod 15, so that the angle between the first connecting rod 13 and the movable ring 6 can be changed, and the angle between the second connecting rod 15 and the outer wall of the charging gun 1 can be changed.

[0030] Among them, a connecting groove 14 is opened through the middle of the first connecting rod 13, the top end of the second connecting rod 15 is located inside the connecting groove 14 and is rotatably connected to the first connecting rod 13, and multiple first connecting rods 13 and connecting grooves 14 are provided.
