The battery box is provided with press buckling steps, the overturning box is fixedly provided with a hinged plate, the press buckling plate is hinged with the hinged plate through a bolt, the bolt is sleeved with a spring, and the spring enables the end part of the press buckling plate to be kept in press buckling at the press buckling steps so as to fix the battery box in the overturning box.
The rotating disc is hinged with a linkage hinge plate, and the linkage hinge plate is hinged with one end of the positioning claw.
The positioning plate is provided with an L-shaped positioning portion, the positioning pawl is provided with an L-shaped buckling portion corresponding to the L-shaped positioning portion, and the L-shaped buckling portion is provided with a vertical positioning clamping groove and a transverse positioning clamping groove which can buckle the positioning plate.
The frame is provided with a fixed support, and two sides of the fixed plate are fixed on the fixed support.
The fixed plate is hinged with the turnover box through a hinge.
The frame is provided with a connecting vertical plate, and the screw rod motor is fixedly connected with the connecting vertical plate.
The invention has the following beneficial effects:
when the battery box is used and needs to be taken out for charging, the pull rod is displaced through the lead screw motor, the pull rod moves, the turnover box rotates around the fixed plate through the turnover pull plate, the opening of the turnover box is upward, and the pressing buckle plate is manually pressed to lift the battery box for charging; under the normal use state, the screw rod motor can not rotate under the condition of no power supply, so that the turnover box can not rotate, and at the moment, even if the fixing of the pinch plate is released, the space between the turnover box and the frame can not lift the storage battery box, so that the anti-theft effect is achieved.
When a screw motor works to drive a turnover box to turn over, a driving motor in the positioning and fixing device synchronously works and rotates, and a rotating disc connected with the driving motor pulls the end part of a positioning claw to move inwards, so that the other end of the positioning claw is released from being clamped with the end part of a positioning plate on the rotary box; effectual assurance upset case is at the fastness under the not upset state, further prevents that it from rocking.

Detailed Description
The invention is further elucidated with reference to the accompanying drawings.
Referring to fig. 1 to 3, the invention provides a battery jar placing and turning device for an electric vehicle frame, which comprises a vehicle frame 1, a fixing plate 2, a screw motor 3, a turning box 4 and a battery jar box 5, wherein the fixing plate 2 and the screw motor 3 are fixedly connected with the vehicle frame 1, the vehicle frame 1 is provided with a fixing support 6, two sides of the fixing plate 2 are fixed on the fixing support 6, the vehicle frame 1 is also provided with a connecting vertical plate 7, and the screw motor 3 is fixedly connected with the connecting vertical plate 7; the lead screw motor 3 is in circuit connection with a circuit control system of the electric car, the lead screw motor 3 is controlled to rotate by the circuit control system only under the condition that a power supply is connected, the lead screw motor 3 cannot rotate under the condition that the power supply is not available, namely, the turnover box 4 cannot rotate, so that the storage battery box 5 in the turnover box 4 cannot be taken out, and the storage battery in the storage battery box 5 is prevented from being stolen; the turning box 4 is hinged to the fixing plate 2 through a hinge 8, and the storage battery box 5 is placed in the turning box 4; be provided with a upset arm-tie 9 on the upset case 4, the transmission is connected with a pull rod 10 on the lead screw motor 3, and pull rod 10 one end is articulated with upset arm-tie 9, it has a buckle 11 to articulate on the upset case 4, and buckle 11 withholds battery box 5 and fixes in upset case 4, and lead screw motor 3 rotates and drives pull rod 10 and take place the displacement to make upset case 4 rotate around hinge 8 on the fixed plate 2 through upset arm-tie 9, until upset case 4 opening up, manually press buckle 11, remove the buckle and can take out battery box 5.
