Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

This embodiment discloses a hand hay cutter formula is waterproof battery interface for electric motor car and including the electric motor car of this waterproof battery interface, and the electric motor car includes the automobile body, and waterproof battery interface sets up on the automobile body. As shown in fig. 1 to 4, the waterproof battery interface includes a connector body 1, a battery mechanism 2 and a sealing ring 3, the battery mechanism 2 is sleeved on the connector body 1, and the sealing ring 3 is disposed between the battery mechanism 2 and the connector body 1. The seal ring 3 includes a radial sealing portion 31 and an axial sealing portion 32 which are integrally formed, the radial sealing portion 31 is cylindrical, and the axial sealing portion 32 is formed by extending a top edge of the radial sealing portion 31 outward in a radial direction.

When the connector is installed, the annular through hole 34 in the middle of the sealing ring 3 is sleeved on the guillotine connecting base component 12 of the connector body 1, and the inner circumferential surface of the radial sealing part 31 is attached to the outer circumferential surface of the guillotine connecting base component 12. The extending direction of the axial sealing part 32 is basically vertical to the extending direction of the radial sealing part 31, the top surface of the axial sealing part 32 is attached to the bottom surface 13 of the edge of the connector body 1 vertical to the guillotine connecting seat component 12, the installation is convenient, and the installation efficiency is high. The radial sealing part 31 and the axial sealing part 32 which are integrally formed have better waterproof performance, and the area covered by a waterproof area is larger.

In order to ensure that the axial sealing part 32 has good waterproof capability, an accommodating gap 4 for accommodating the axial sealing part 32 is formed between the connector body 1 and the battery mechanism 2, and the height L of the accommodating gap 4 is smaller than the height H of the axial sealing part 32, so that the axial sealing part 32 is in a compression deformation state and can fill the space at the joint of the connector body 1 and the battery mechanism 2; however, the axial sealing portion 32 is not compressed to the flattest, so that the elastic force is prevented from being reduced due to excessive extrusion deformation, and the numerical value of the height L is controlled to be the best sealing and waterproof effect of the axial sealing portion 32.

The specific formation of the receiving space 4 is not limited, and preferably, the connector body 1 is formed with a limit recess 11, and the battery mechanism 2 is formed with a limit stopper 23. The depth of the limiting concave part 11 and the height of the limiting backstop 23 are designed according to the numerical requirement of the height L, so that after the limiting backstop 23 is matched with the limiting concave part 11, an accommodating gap 4 with a numerical value meeting the requirement is formed between the connector body 1 and the battery mechanism 2. The structure has the advantages of convenient processing, low processing cost and high installation effect.

In addition to the above structure, the connector locking hole 111 is formed in the stopper recess 11, the mechanism locking hole 231 is formed in the stopper 23, and the connector locking hole 111 and the mechanism locking hole 231 are connected by the bolt 5. After the limit stop 23 abuts against the limit concave part 11, the height L of the accommodating gap 4 will not be reduced even if the torque of the bolt 5 is too large, and the axial sealing part 32 is always in the best waterproof state.

As shown in fig. 2 and 5, a rib 33 is formed on the outer side surface of the radial seal portion 31 to extend radially outward, and a groove 21 that fits the rib 33 is formed on the inner side surface of the battery mechanism 2. The groove 21 is filled with the rib 33 after installation, so that water vapor can be effectively prevented from permeating between the outer peripheral surface of the radial sealing part 31 and the inner peripheral surface of the battery mechanism 2, and the waterproof effect is good.

The specific shape of the rib 33 is not limited, and preferably, the rib 33 forms an annular structure around the outer circumference of the radial sealing portion 31, so that a circle of structure for blocking the water vapor from entering is formed between the outer circumference of the radial sealing portion 31 and the inner circumference of the battery mechanism 2, and the waterproof effect is better.

In order to further improve the waterproof effect, since the plurality of ribs 33 are formed on the outer side surface of the radial seal portion 31 so as to be spaced apart from each other, a plurality of structures are formed in the axial direction of the radial seal portion 31 so as to prevent moisture from entering between the outer peripheral surface of the radial seal portion 31 and the inner peripheral surface of the battery mechanism 2. Preferably, the rib 33 is hemispherical or a combination structure of a cylindrical structure and a hemispherical structure, so that the processing is convenient, and the waterproof effect is good after the rib is attached to the groove 21.

In addition to the above configuration, the battery mechanism 2 is formed with the pressing rib 22 at a position abutting against the axial seal portion 32, and the pressing rib 22 projects toward the axial seal portion 32. After installation, the pressing ribs 22 are pressed into the axial seal portion 32, so that the contact between the pressing ribs 22 and the axial seal portion 32 is made tighter, and moisture is prevented from permeating between the battery mechanism 2 and the axial seal portion 32.

The specific shape of the pressing ribs 22 is not limited, and it is preferable that the pressing ribs 22 form a ring structure on the battery mechanism 2 around the axis of the battery mechanism 2, so that a waterproof structure is formed between the battery mechanism 2 and the axial seal portion 32, and moisture is prevented from permeating in all directions.

On the basis of above-mentioned structure, sealing washer 3 is preferred to be made by silica gel, and is longe-lived, stand wear and tear, and elastic deformation ability is strong moreover, can laminate with connector body 1 and battery mechanism 2 more closely respectively, and water-proof effects is good.

It should be noted that the foregoing is only a preferred embodiment of the present invention and the technical principles applied. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention.
