Detailed Description

The present invention will be more fully described in the following detailed description of the preferred embodiments thereof, taken together with the accompanying drawings.

Example 1

The embodiment discloses a battery pack leveling device 1, which is used for solving at least one of the problems of heavy weight, high machining precision requirement, complex machining and the like of a tray 11 applied to a battery replacement device.

As shown in fig. 1, the battery pack leveling device 1 is configured to be disposed on a battery mounting portion 3 of a shuttle-type battery replacement device, the battery pack leveling device 1 includes a plurality of trays 11 separately disposed, the plurality of trays 11 are respectively connected to the battery mounting portion 3 in a floating manner, and the plurality of trays 11 are used for placing a battery pack 200. Specifically, a plurality of trays 11 all float and connect on battery installation department 3, have improved tray 11's degree of freedom, and then can improve the degree of freedom of placing battery package 200 on tray 11 when a plurality of trays 11 bear battery package 200 jointly for can carry out the fine setting along the flexible direction of elastic component 4 through tray 11 when installing battery package 200, realize the steady contact of battery package 200 with electric automobile 300 bottom. In addition, when the battery pack 200 is unlocked, the tray 11 can better accommodate the inclination of the vehicle due to load or the like when the battery pack 200 is removed from the electric vehicle 300 and is mounted on the electric vehicle 300, and the battery pack 200 can be conveniently positioned. For the separately arranged trays 11, by adopting the structure, compared with the integrally large-area tray 11, the separately arranged trays 11 have the advantages that the overall weight is lighter and the inertia is smaller while the bearing range is unchanged; the tray 11 which is arranged separately is more convenient to arrange more mechanisms for realizing floating; furthermore, the tray 11 arranged in a split manner avoids the defect that the precision requirement for processing a large-size integrated tray is high, and also avoids the defect that the processing of a combined (such as welding combined) large-size tray is complex.

Two trays 11 are arranged, and the two trays 11 are arranged side by side at intervals along the walking direction of the shuttle-type battery replacing equipment. By adopting the above structure, under the condition that the battery pack 200 can be normally placed, the weight of the trays 11 is reduced, and the two trays 11 are arranged side by side at intervals along the walking direction of the shuttle type battery replacing device, so that the swing of the battery pack 200 in the walking direction (especially when the battery replacing device starts and stops) can be better inhibited, and the stable placement of the battery pack 200 is ensured. In other embodiments, the number of trays 11 may be other numbers, and is not limited herein.

Along the walking direction of the shuttle-type battery replacing device, the distance between the outer edges of the two trays 11 is 60% -70% of the length of the battery pack 200, so that the stable placement of the battery pack 200 is better realized, and the service life of the battery pack 200 is prolonged. Specifically, since the two trays 11 are symmetrically arranged about the middle position of the battery pack 200 in the length direction, if the distance between the two trays 11 is longer, the bending moment applied to the middle position of the tray 11 is also larger, which affects the service life of the battery pack 200. In addition, if the distance between the two trays 11 is smaller, the length of the battery pack 200 that the two ends of the battery pack 200 extend out of the trays 11 is longer, so that the two ends of the battery pack 200 are subjected to larger bending moment, which affects the service life of the battery pack 200. Therefore, the distance between the outer edges of the two trays 11 is 60% -70% of the length of the battery pack 200, so that the bending moments applied to the two ends and the middle of the battery pack 200 can be balanced, and the service life of the battery pack 200 is prolonged. In other embodiments, the distance between the outer edges of the two trays 11 is anywhere between 50% -100% of the length of the battery pack 200.

Two trays 11 are floatingly provided at the edges of two opposite sides of the battery mounting portion 3. With the above configuration, the distance between the two trays 11 for supporting the battery pack 200 is increased as much as possible without interfering with the movement of the battery mounting portion 3, thereby improving the stability of the battery pack 200.

A through hole 111 penetrating the tray 11 is provided in a portion of the tray 11 for accommodating the battery pack 200, and the through hole 111 is used for the unlocking member 2 provided in the battery mounting portion 3 to pass through to position and unlock the battery pack 200. Specifically, since the tray 11 is floatingly attached to the battery mounting portion 3, the above-mentioned floating may be either a horizontal floating or a vertical floating. That is, the tray 11 may be moved in a direction toward the battery mounting portion 3 or in a direction away from the battery pack 200 mounting portion 3 by an external force. By adopting the structure, the battery pack 200 is placed on the tray 11, so that the tray 11 moves towards the direction close to the battery mounting part 3 under the action of the gravity of the battery pack 200, the unlocking piece 2 extends out of the through hole 111 for a longer length, and the unlocking piece 2 can extend into the battery pack 200 to position the battery pack 200, thereby improving the placing stability of the battery pack 200; that is, the battery pack 200 is placed on the tray 11, and the tray 11 is moved downward relative to the battery mounting portion 3 by the gravity of the battery pack 200, so that the unlocking member 2 is inserted into the battery pack 200 to position the battery pack 200. In other words, the through-hole 111 facilitates the unlocking member 2 to be inserted into the battery pack 200 to position the battery pack 200. When the battery pack 200 is removed from the electric vehicle 300, the battery mounting portion 3 drives the tray 11 to move up, and after the upper surface of the tray 11 is attached to the lower surface of the battery pack 200, the tray 11 cannot move up any more. But unlocking part 2 moves upwards under the drive of unlocking device, so that the length of unlocking part 2 extending out of through hole 111 is lengthened, and unlocking part 2 can extend into battery pack 200 to contact with ejector rod 101 and eject ejector rod 101 out of battery pack 200. The ejector rod 101 ejected out of the battery pack 200 can trigger the locking mechanism 9, so that the battery pack 200 is unlocked. By adopting the structure, the bearing and the positioning of the battery pack 200 are respectively realized by the tray 11 and the unlocking piece 2 separated from the tray 11, so that the tray 11 can be directly formed by using a metal plate (such as a steel plate), the related structures (such as a limit block and the like) for positioning the battery pack 200 are not required to be arranged on the tray 11, and the forming is more convenient; in addition, the positioning function of the battery pack 200 is integrated on the unlocking piece 2, the integration level is improved while the unlocking function is not influenced, the work is more reliable, and the defect that the unlocking structure is complex because the positioning and the unlocking are respectively borne by the tray 11 (for example, a limit block is arranged on the tray 11) and the unlocking piece 2 in the prior art is overcome.

The edge of tray 11 is formed with the turn-ups 112 that the orientation extended far away from battery package 200, and then has improved the bending strength of tray 11 through tray 11 to turn-ups 112 is to keeping away from battery package 200 orientation extension, also can prevent that turn-ups 112 from producing the interference to battery package 200. In addition, when the battery pack 200 is placed on the tray 11, the battery pack 200 will contact with the edge of the tray 11, and the edge can be prevented from damaging the battery pack 200 by the flanging 112, thereby prolonging the service life of the battery pack 200. Specifically, the tray 11 includes a placing plate for contacting the battery pack 200 and the placing plate is a flat surface, which increases the contact area of the battery pack 200 and the battery pack 200, thereby improving the stability of placing the battery pack 200, and a burring 112. The flanges 112 are formed at the edges of the placing plates, as shown in fig. 1 and 3, the flanges 112 are arranged on two opposite sides of each placing plate in the traveling direction of the battery replacing device, the flanges 112 are as long as the edges of the placing plates where the flanges 112 are located, and the placing plates are reinforced in the whole length of the edges where the flanges 112 are located, so that the bending strength of the tray 11 is improved better.
