Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "central," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," "circumferential," and the like are used in the indicated orientations and positional relationships based on the drawings for convenience in describing and simplifying the description, but do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the invention.

In the present invention, unless otherwise specifically stated or limited, the terms "mounted," "connected," "fixed," and the like are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; the connection can be mechanical connection, electrical connection or communication connection; either directly or indirectly through intervening media, either internally or in any other suitable relationship, unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.

Example 1: the utility model provides an electric motor car storage battery shock attenuation positioner, shock attenuation positioner sets up in the space of storage battery installation frame 2, including setting up the elasticity balance mechanism in 1 below of storage battery, elasticity balance mechanism includes that the central part is used for bearing storage battery 1's balance support plate 3 and sets up the balance spring 4 in 3 four end points of balance support plate, and 3 central parts that carry on the back in 1 one side of storage battery of balance support plate are equipped with rigid support rod 5, and rigid support rod 5 is connected on balance support plate 3 with ball pivot 6. When the electric vehicle bumps in the driving process, the storage battery 1 drives the balance support plate 3 to rotate around the rigid support rod 5 connected with the ball shaft 6 as an axis, so that the balance spring 4 at the corresponding position is pressed, the balance support plate 3 can be immediately pushed back to the original position by the feedback force generated after the balance spring 4 is compressed, and the balance positioning of the storage battery 1 is ensured.
