Example two:
in this embodiment, the edge of the battery receptacle 5 is provided with a plurality of rollers 51, and the plurality of rollers 51 are provided at intervals along the sliding direction of the battery grasping mechanism 6. Specifically, the axial lines of the rollers 51 are perpendicular to the sliding direction of the battery grasping mechanism 6, and the axial lines of the rollers 51 are parallel to each other.
Thus, the battery slides on the roller 51, and the friction between the battery and the roller 51 is small, so that the sliding is smooth.
In addition, rollers 41 are provided on both sides of the rotary base 4, the rollers 41 are vertically provided in plurality, and the rollers 41 are provided at intervals along the sliding direction of the battery grasping mechanism 6. Specifically, the axes of the rollers 41 are perpendicular to the sliding direction of the battery grasping mechanism 6, and the axes of the rollers 41 are parallel to each other.
Thus, when the battery is pulled into the battery receptacle 5, the battery receptacle 5 slides along the rotary seat 4, the side surface of the battery 11 slides along the roller 41, and the transverse direction of the battery 11 is positioned, so that the battery 11 can be accurately placed on the battery rack 7.
In addition, positioning rods 52 are provided on both sides of the front end of the battery receptacle 5.
Thus, the positioning holes are formed in the automobile or the battery placing frame 7, and the positioning rods 52 are inserted into the positioning holes, so that the positioning between the battery receiving seat 5 and the automobile or the battery placing frame 7 is realized, and the battery grabbing mechanism 6 can grab the battery more accurately.
In addition, the end of the positioning rod 52 is tapered.
Thus, when there is a small error between the positioning rod 52 and the positioning hole, the end of the positioning rod 52 is tapered, and the positioning rod 52 can still be inserted into the positioning hole.
In summary, the above description is only a preferred embodiment of the present invention and should not be taken as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention should be included within the scope of the present invention.
