Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description will be given to the embodiments, structures, features and effects of the protective structure of the American standard charging socket elastic cover according to the present invention with reference to the accompanying drawings and preferred embodiments.

Please refer to fig. 1-4, which are schematic structural views of each part of the protective structure of the American standard charging socket elastic cover of the present invention, the protective structure includes a square disc housing 1, the square disc housing 1 is provided with a dc socket and an ac socket, and the dc socket and the ac socket are both covered and protected by a protective elastic cover 2 hinged on the square disc housing 1. The square plate shell 1 is located a mounting groove is formed in the position below the hinged end of the protection elastic cover 2, an elastic supporting piece is arranged in the mounting groove, the top of the elastic supporting piece is provided with a roller 9, and the protruding structure 7 at the bottom of the protection elastic cover 2 is pressed on the roller 9 to enable the elastic supporting piece to have upward elastic restoring force all the time. According to the invention, the rolling connector of the protective elastic cover 2 and the elastic supporting piece is realized through the convex structure and the roller 9, and when the protective elastic cover 2 is completely covered or opened, the force of the elastic supporting piece on the convex structure 7 is vertically upward, so that the protective elastic cover has a vertically upward force, and the protective elastic cover 2 is kept covered or opened.

In the embodiment of the invention, the convex structure comprises an arc transition part with a smooth middle and a support part with tangential directions at two sides respectively parallel to and perpendicular to the elastic support member, so that when the protective elastic cover 2 is completely covered or opened, the state of the protective elastic cover can be kept under the elastic action of the elastic support member.

In the embodiment of the invention, the outer side of the hinged end of the protective elastic cover 2 is further provided with a limiting structure 6 which is matched with the outer wall of the installation groove of the elastic supporting piece in a stop manner to limit the opening angle of the protective elastic cover 2.

For the reliability of reinforcing protection bullet lid, prevent that it from opening by mistake, still through retaining member locking, the preferred between protection bullet lid 2 and the square stock casing, the retaining member is buckle structure. In the embodiment of the invention, a buckle structure 4 is arranged at one end of the protective elastic cover 2 opposite to the hinged end, a shaft pin 8 is arranged at the corresponding position on the square disc shell, and the buckle structure 4 is tightly clamped on the shaft pin 8 to ensure the locking of the elastic cover.

in the embodiment of the present invention, the elastic supporting member is composed of a supporting rod 10 and an elastic member supported below the supporting rod 10, preferably, the elastic member is a spring 11, the roller 9 is rolled on a supporting plate at the upper part of the supporting rod 11, and the spring 11 presses on the bottom of the supporting plate.

In the embodiment of the present invention, the lower portion of the mounting groove of the elastic supporting member is further provided with an inner step surface for stopping the supporting plate of the supporting rod 10.

In the embodiment of the invention, one of the protection elastic covers of the alternating current socket and the direct current socket is provided with a protection elastic cover which is pressed, the other protection elastic cover is not provided with a locking structure, the protection elastic cover pressed on the protection elastic cover realizes locking, and when the protection elastic cover pressed on the protection elastic cover is opened, the buckling shape is maintained through the elastic force of the elastic support part. Specifically, the protruding portion of one end of the upper protection elastic cover is pressed on the recessed portion of the corresponding end of the lower protection elastic cover between the two protection elastic covers to lock the lower protection elastic cover, but the invention is not limited thereto.

When the protective structure of the American standard charging socket elastic cover is locked, an upward force is applied to the convex structure of the elastic cover by the aid of the cooperation of the spring and the roller, meanwhile, the right-side buckle structure is clamped on the pin shaft, locking of the elastic cover is guaranteed, when the protective structure is unlocked, a certain force needs to be applied to the elastic cover, the elastic cover is opened, after the elastic cover is in place, the opening angle of the elastic cover is guaranteed by the limiting structure on the elastic cover, in this state, the requirement of alternating current charging can be met, namely, when alternating current charging is carried out, the direct current part interface can still be effectively protected, and when a vehicle needs direct current charging, the alternating current elastic cover is firstly opened, and then the direct current elastic cover is opened.

in another embodiment of the invention, the mutual connection relationship between the protection elastic covers of the alternating current socket and the direct current socket is not influenced, and only the corresponding protection elastic cover needs to be opened when charging is needed.

although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
