For an electric automobile, charging of a charging pile and replacement of a battery are two ways for realizing the endurance of the electric automobile. The battery replacement is to replace the battery to be charged on the vehicle, take out the charged battery from the battery charging rack to replace the battery to be charged, and place the battery to be charged in the charging cavity for charging. However, since the battery of the electric vehicle is generally transported to the charging chamber by the transporting equipment such as the forklift, and the inlet of the charging chamber is highly matched with the size of the battery, the battery can be accurately transported into the charging chamber from the inlet only by the skilled operation of the operator, if the battery cannot be placed once, the battery is dislocated with the inlet, and the battery has to be transported by multiple adjustments, which seriously affects the working efficiency. With the development of the technology, there is a system capable of automatically charging and replacing batteries.

For example, chinese patent No. CN201811065605.3 discloses a battery fixing device for a large-scale vehicle battery replacement station, which includes a battery rack, a battery guide block and a locking mechanism; a battery guide block is arranged on the side edge of the battery frame; a battery locking mechanism is arranged on the battery frame; and the battery rack is provided with a positioning pin.

For another example, chinese patent No. CN201810961137.1 discloses an automatic charging and replacing system and an automatic charging and replacing method for an electric vehicle. According to the scheme, the battery assembly is accommodated in the accommodating cavity, a motor receiving and outputting piece is arranged at one end, close to the baffle, of the battery pack, and a magnetic piece is arranged at one end, close to the baffle, of the movable support; the charging device comprises a supporting table, a supporting plate formed by protruding from one side of the supporting table, an electromagnetic matching piece capable of generating magnetic attraction effect on the magnetic piece and a charger used for being electrically connected with the motor output piece; when the supporting plate is contacted with the baffle plate, the baffle plate is changed from a closed state to an open state, so that the battery component leaves the accommodating cavity under the magnetic attraction effect of the electromagnetic matching piece on the magnetic piece and moves along the supporting plate until the motor connecting piece is electrically contacted with the charger. However, this solution has the following drawbacks: through the magnetic force action generated by the electromagnetic matching piece, a part of electric energy needs to be consumed, and some unnecessary energy loss can be caused; in addition, due to the use of the electromagnetic mating part, a certain magnetic field is generated nearby, the positive electrode material of the battery forming current during charging and discharging is a compound of metal ions, when the battery is charged and discharged, the metal ions move from one pole to the other pole, and if a strong magnetic field is applied, the metal ions are interfered by the magnetic field to influence the charging state of the battery. Therefore, there is a need in the art to develop a new battery charging platform.

In one possible embodiment, the third positioning portion 160 is provided on the first positioning portion 130, the third positioning portion 160 is also plate-shaped, and is fixed to the upper surface of the first positioning portion 130, and the tip of the rectangular triangle 172 also protrudes from the end surface of the third positioning portion. A horizontal slide rail 158 is provided at the upper end of the third positioning portion, and the horizontal slide rail 158 is connected to the bottom of the lateral plate 157 by a sliding horizontal slider 159. The bottom of the transverse plate 157 is connected to the axle 182 by a connecting block 180.

The operation principle is as follows: when the battery assembly moves down and falls on the first positioning portion 130, the first positioning portion 130 is forced to approach the second positioning portion 140, and the return spring is compressed. At the same time, the horizontal sliding rail 158 fixedly connected to the first positioning portion 130 also moves downward. In the downward movement process of the horizontal sliding rail 158, the first guiding portion 170 is driven to move downward by a sliding fit manner. However, since one end of the first guide portion 170 is obliquely guided by the inclined guide groove 171, the first guide portion 170 is simultaneously compositely horizontally slid while moving down. I.e. finally the charging interface is engaged with the charging connector by means of the compound movement of the first guiding portion 170.

It should be emphasized that, in order to avoid the vertical separation between the horizontal sliding rail 158 and the horizontal sliding block 159, in this embodiment, the horizontal sliding rail 158 is an i-shaped rail, and two side wings of the horizontal sliding block 159 respectively and correspondingly embrace into the side space in the middle of the horizontal sliding rail 158, so as to achieve the tight limit of the horizontal sliding rail 158 and the horizontal sliding block in the direction vertical to the length direction of the rail.

In this embodiment, the gravity of the battery assembly is used as the driving force, the first positioning portion and the second positioning portion which are in floating fit with each other are used for realizing the combined motion of the first guiding portion 170, so that the automatic fit and the automatic power-off return of the power assembly and the charging connector are skillfully realized instead of manual work, the practical value is high, and an important automatic reform function is played for the charging program of the electric vehicle.

To further facilitate the movement of the charging positioning portion 150 in the horizontal direction, one end of the plate-shaped body 154 is connected to a piston end of a propulsion cylinder for driving the charging positioning portion to move linearly relative to the first positioning portion, so as to be closer to a charging interface of the battery assembly.
