Detailed Description

In order to make the technical solution of the present invention more apparent, the present invention is further described in detail with reference to the following examples, and it should be understood that the specific embodiments described herein are only used for explaining the present invention, and are not used for limiting the present invention.

Referring to the attached drawings 1-3, the plastic shell of the storage battery with the shock absorption and protection functions of the utility model comprises an inner shell 1, an outer shell and a cover body, an accommodating space for accommodating the liquid of the storage battery is arranged in the inner shell 1, the inner shell 1 is connected with the cover body, the outer shell comprises four panels 2, the four faces of the panels 2 and the inner shell 1 are connected through springs 3, one end of each spring 3 is connected with the outer surface of the inner shell 1, the other end of each spring 3 is connected with the inner surface of the panel 2, a force unloading device is arranged between the panel 2 and the corresponding inner shell 1, the force unloading device comprises an inclined rod 4, a guide rod 9 and a roller 6, one end of the inclined rod 4 is hinged with the inner side of the panel 2, the other end of the inclined rod 4 and one end of the guide rod 9 are hinged with the roller 6, the roller 6 can be arranged on the surface of the inner shell 1 in a sliding way, and the other end of the guide rod 9 is connected with the adjacent panel 2.

When the whole storage battery is placed at a use position, if the outside is collided by an external force, the common external relay is impacted from a single surface, the panel 2 moves inwards, the spring 3 is compressed at the moment, the spring 3 plays a role in damping the first step, the inclined rod 4 is also compressed inwards to drive the roller 6 to slide, the guide rod 9 is pushed to push the panel 2 on the other side outwards at the same time, and the restoring force of the spring 3 of the adjacent panel 2 must be overcome in the pushing process, so that the damping of the second step is achieved.

Through two-step shock attenuation, can direct furthest's elimination impact, guaranteed the stability of whole battery, greatly reduced the loss that the striking brought, because the structure that sets up is more, and the cost is also higher, therefore this structure is fit for some non-maintaining batteries.

Similarly, when the panel 2 moves, not only the inclined rod 4 of the panel is pushed, but also the guide rod 9 of the adjacent cooperative device is pushed, and the included angle of the corresponding inclined rod 4 is reduced, so that the cooperative action of the other two panels 2 is realized when one panel 2 is stressed.

In order to prevent the four panels 2 from colliding with each other, in the present embodiment, gaps 7 are provided between the four panels 2.

The interior casing 1 corresponds guide bar 9 and gyro wheel 6 and is provided with guide way 8, and guide bar 9 and gyro wheel 6 remove along guide way 8, have guaranteed the accuracy that guide bar 9 and gyro wheel 6 removed, have promoted the life-span.

The surface of the inner shell is provided with a lantern ring, the guide rod penetrates through the lantern ring, the lantern ring limits the circumferential freedom degree of the guide rod, and only guiding in the guide groove is performed.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
