Locking block is arranged at battery swap station site, and locking block 2 is internally provided with grooved part 3, movable installation lock tongue 4 in grooved part 3, lock tongue 4 is C character shape structure, lock tongue can rotate relative to locking block, the compression part 5 of lock tongue 4 upper end extends the upper opening 6 of grooved part 3, the stress part 7 of lock tongue 4 lower end extends the lower opening 8 of grooved part 3, movable block 1 is located stress part 7 top, when rotating lock tongue 4, when the stress part 7 of lock tongue 4 lower end extends the lower opening 8 of grooved part 3 and moves down, the compression part 5 of lock tongue 4 upper end extends outside the upper opening 6 of grooved part 3, on the contrary, when the stress part 7 of lock tongue 4 lower end extends the lower opening 8 of grooved part 3 and moves up, the compression part 5 of lock tongue 4 upper end contracts inside the upper opening 6 of grooved part 3. In this way, when battery pack is close to locking, battery pack is close to locking and is placed to movable block 1 top, after movable block 1 is subjected to the pressure of battery pack close to locking downward, movable block 1 moves down, and the downward force is exerted on the stress part 7 of locking block 2, at this time, lock tongue 4 rotates, the stress part 7 of lock tongue 4 lower end extending the lower opening 8 of grooved part 3 moves down, the compression part 5 of lock tongue 4 upper end extends outside the upper opening 6 of grooved part 3, after movable block 1 moves down in place, the compression part 5 is abutted on the side surface of battery pack close to locking, realizes the clamping of battery pack close to locking. When battery pack close to locking is needed to be taken away, only need to exert force on battery pack close to locking, battery pack close to locking moves up, then the force exerted on movable block 1 by battery pack close to locking disappears, then movable block 1 does not exert force on the stress part 7 of locking block 2, and the force exerted on the side surface of battery pack close to locking by the compression part 5 also disappears, so that battery pack can be conveniently taken away. The battery pack locking device of battery swap station, simple structure, can conveniently and reliably realize battery pack locking, and is convenient and fast to dismount battery pack, satisfies the high efficiency rhythm of battery swap station. The whole device is reliable when locking battery pack, and is convenient to take away.

[0025] The two locking blocks 2 are symmetrically arranged on both sides of the movable block 1, one side of the movable block 1 is above the stress receiving part 7 of one locking block 2, and the other side of the movable block 1 is above the stress receiving part 7 of the other locking block 2. The above structure, the two symmetrically arranged locking blocks, when the battery pack is placed, the locking tongues of each locking block are respectively turned inward, the compression part is simultaneously extended outward, can be compressed from both sides at the same time, and reliable locking is achieved.

[0026] The locking block 2 includes a vertical part 9 and a horizontal part 10, which are arranged in an L-shaped structure, the movable block 1 is located between the two vertical parts 9 of the two locking blocks 2, and the movable block 1 is located between the two horizontal parts 10 of the two locking blocks 2. The above structure, the vertical part 9 and the horizontal part 10 are an integral structure, the movable block is located between the two locking blocks, when the battery pack is placed on the movable block, the locking tongues of the two locking blocks are simultaneously extended and stressed, and locking is achieved. The inner side of the horizontal part 10 of the locking block 2 is provided with a locking block inclined surface 11, the side of the movable block 1 is provided with a movable block inclined surface 12, and the locking block inclined surface 11 and the movable block inclined surface 12 are arranged in parallel. The above structure, when the movable block 1 is not subjected to downward force, there is a gap between the movable block inclined surface 12 of the movable block 1 and the locking block inclined surface 11 of the locking block 2, and when the movable block 1 is subjected to downward force, the movable block inclined surface 12 and the locking block inclined surface 11 are finally in contact, at this time, the movable block 1 will not continue to move downward, and the limiting of the movable block 1 is achieved.

[0027] The compression part 5 of the upper end of the locking tongue 4 extends an upper opening 6 above the vertical part 9, the stress receiving part 7 of the lower end of the locking tongue 4 extends a lower opening 8 below the vertical part 9, and the locking tongue 4 is movably installed in the slotted part 3 through a pin shaft. The above structure, the locking tongue 4 rotates around the pin shaft as the center, and the upper opening and the lower opening will not hinder the movement of the locking tongue within a certain range.

[0028] The locking tongue 4 and the slotted part 3 inside the locking block 2 are provided with a reset spring 13. After the external force applied by the movable block to the stress receiving block disappears, the reset spring rebounds and applies a reset force on the locking tongue, pushes the compression part to retract into the upper opening, and the stress receiving part moves upward to complete the reset.

[0029] The movable block 1 is provided with an extension part 14 on the side, the extension part 14 side is close to the inner side of the vertical part 9 of the locking block 2, and the stress receiving part 7 of the lower end of the locking tongue 4 is located below the extension part 14. The above structure, after the battery pack is placed, the movable block moves downward, the compression part 5 of the locking tongue applies force on the side of the battery pack, and the side of the extension part of the movable block can contact the inner side of the vertical part or not. As long as there is a force applied by the battery pack, the compression parts 5 on both sides can reliably apply force on the side of the battery pack, and the battery pack is clamped and locked from the two symmetric positions.

[0030] The horizontal part 10 of the locking block 2 is fixed on the battery swap station base. The above structure can fix the position of the locking block by bolt connection on the battery swap station base. For the battery pack with large size, a plurality of locking block assemblies can be arranged on the battery swap station base, each locking block assembly includes two symmetrically arranged locking blocks, and an active block is arranged between the two locking blocks of each locking block assembly, so that the clamping and locking of the battery pack side from different parts can be realized. For the battery with small size, one locking block assembly and one active block can be used.

[0031] The upper surface of the active block 1 is a plane structure, and the vertical part 9 of the locking block 2 is higher than the upper surface of the active block 1. The above structure ensures that the pressing part reliably applies force to the side of the battery pack.

[0032] The battery pack locking device of the battery swap station comprises an active block 1 and a locking block 2, and the active block and the locking block are used in cooperation. The locking block is arranged on the battery swap station site, and a slot part 3 is arranged in the locking block 2. A lock tongue 4 is movably arranged in the slot part 3. The lock tongue 4 has a C-shaped structure. The lock tongue can rotate relative to the locking block. A pressing part 5 at the upper end of the lock tongue 4 extends out of an upper opening 6 of the slot part 3. A force receiving part 7 at the lower end of the lock tongue 4 extends out of a lower opening 8 of the slot part 3. The active block 1 is located above the force receiving part 7. When the lock tongue 4 rotates, when the force receiving part 7 at the lower end of the lock tongue 4 extends out of the lower opening 8 of the slot part 3 and moves downward, the pressing part 5 at the upper end of the lock tongue 4 extends out of the upper opening 6 of the slot part 3. Conversely, when the force receiving part 7 at the lower end of the lock tongue 4 extends out of the lower opening 8 of the slot part 3 and moves upward, the pressing part 5 at the upper end of the lock tongue 4 retracts into the upper opening 6 of the slot part 3. In this way, when the battery pack needs to be placed close to the locking block, the battery pack is placed close to the locking block above the active block 1. After the active block 1 is subjected to the downward pressure of the battery pack close to the locking block, the active block 1 moves downward and applies downward force on the force receiving part 7 of the locking block 2. At this time, the lock tongue 4 rotates, the force receiving part 7 at the lower end of the lock tongue 4 extends out of the lower opening 8 of the slot part 3 and moves downward, and the pressing part 5 at the upper end of the lock tongue 4 extends out of the upper opening 6 of the slot part 3. After the active block 1 moves downward to the position, the pressing part 5 abuts against the side of the battery pack close to the locking block, thereby realizing the clamping of the battery pack close to the locking block. When the battery pack close to the locking block needs to be removed, only upward force needs to be applied on the battery pack close to the locking block. The battery pack close to the locking block moves upward, the force applied by the battery pack close to the locking block on the active block 1 disappears, the active block 1 does not apply force on the force receiving part 7 of the locking block 2, and the force applied by the pressing part 5 on the side of the battery pack close to the locking block also disappears, so that the battery pack can be conveniently removed. The battery pack locking device of the battery swap station has a simple structure, can conveniently and reliably realize the locking of the battery pack, is convenient and fast for dismounting the battery pack, meets the high-efficiency replacement rhythm of the battery swap station, reliably locks the battery pack, and is convenient for removal.
