In order to achieve the above purpose, the present invention is achieved by the following technical solutions.

The utility model provides a pure electric vehicles quick change battery locking mechanism, includes the base, with automobile body fixed connection, be provided with supporting seat and locking mechanism on the base, be provided with spacing fixed slot on the supporting seat for place and the lock axle of fixed battery package, locking mechanism includes the stopper and blocks the piece, it is provided with tappet and resilience structure in the piece to block, resilience structure sets up the tappet with in the cavity between the piece inner wall blocks, the one end of stopper with tappet fixed connection, the other end is used for blockking the spacing post on the battery package.

Furthermore, the supporting seat is of a U-shaped structure, and the U-shaped edge is long at the top and short at the bottom.

Furthermore, the limiting block is L-shaped.

Further, the lock shaft of the battery pack is cylindrical.

Further, the resilient structure is a spring.

The utility model discloses produced beneficial effect for prior art does: simple structure, high reliability, low cost, high strength and long service life.

the device comprises a base 1, a left longitudinal beam 2, a right longitudinal beam 3, a front cross beam 4, a rear cross beam 5, a support seat 6, a locking mechanism 30, a limiting block 31, a blocking block 32, a tappet 33, a spring 34 and a limiting shaft 35.

Detailed Description

In order to make the technical problem, technical scheme and beneficial effect that the utility model will solve more clearly understand, combine embodiment and attached drawing, it is right to go on further detailed description the utility model discloses. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The technical solution of the present invention is described in detail below with reference to the embodiments and the drawings, but the scope of protection is not limited thereto.

As shown in fig. 1, be the utility model discloses a locking mechanism, including base 1, base 1 includes left longeron 2, right longeron 3, front beam 4 and rear frame member 5, and base 1 passes through front beam 3 to be fixed on the automobile body, and left longeron 2 and right longeron 3 are symmetrical structure, and the battery package is placed on base 1.

The left side edge and the right side edge of the battery pack are respectively and symmetrically provided with seven cylindrical lock shafts, a limiting shaft and limiting blocks, and the limiting blocks are matched with the left longitudinal beam 2 and the right longitudinal beam 3 to limit the battery pack to move left and right in the Y direction.

Seven supporting seats 6 are symmetrically arranged on the inner side edges of the left longitudinal beam 2 and the right longitudinal beam 3 respectively, the supporting seats 6 are U-shaped, the U-shaped edges are long and short, the opening directions of the U-shaped supporting seats face backwards, seven locking shafts are arranged on the battery pack, and the supporting seats and the locking shafts are matched to limit the battery pack to move up and down in the Z direction and move forward in the X direction.

The inner sides of the left longitudinal beam 2 and the right longitudinal beam 3 are symmetrically provided with a locking mechanism 30 respectively, the locking mechanism 30 comprises a limiting block 31 and a blocking block 32, the blocking block 32 is hollow, a tappet 33 is arranged at the hollow position, a spring 34 is arranged in a cavity between the tappet 33 and the blocking block 32, the limiting block 31 is L-shaped, one side of the L-shaped limiting block 31 is arranged at the upper end of the blocking block 32 and is fixedly connected with the tappet 33, and the position of the other side of the L-shaped limiting block is matched with the position of a limiting shaft of a battery pack and is used for limiting the battery pack to move backwards in the X direction.

The battery package is placed the utility model discloses a be in normal locking state among the locking mechanism, stopper 31 among the locking mechanism 30 this moment hugs closely spacing axle 35 of battery package and makes the battery package can't make in X to the backward movement, the lock hub spindle of battery package is arranged in U type supporting shoe, make the battery package can't move forward and Z to reciprocating in X, locking mechanism 30 is in the locking state, that is, through the support seat 6 with the locking axle cooperation of battery package and the stopper among the locking mechanism and the spacing axle 35 cooperation of battery package make the stable fixing of battery package on the automobile body.

During unlocking, the lower end of the tappet 33 is pushed by external force, the spring 34 is compressed, the tappet 33 moves upwards, the limiting block 31 moves upwards along with the tappet 33, therefore, a backward moving space is formed in the limiting shaft of the battery pack in the X direction, the battery pack moves backwards, the battery pack is taken out until the position of the locking shaft exceeds the U-shaped supporting seat 6, unlocking is achieved, the spring 34 returns after unlocking, the tappet 33 is pulled to move downwards, and the locking mechanism is enabled to recover the locking state.

The above description is for further details of the present invention with reference to specific preferred embodiments, and it should not be understood that the embodiments of the present invention are limited thereto, and it will be apparent to those skilled in the art that the present invention can be implemented in a plurality of simple deductions or substitutions without departing from the scope of the present invention, and all such alterations and substitutions should be considered as belonging to the present invention, which is defined by the appended claims.
