It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

According to the embodiment of the utility model provides a first aspect provides a frock is fixed to battery package. The battery pack fixing tool is applied to the field of battery pack transportation. In the process of transporting the battery pack, the battery pack fixing tool plays a role in fixing the battery pack.

Referring to fig. 1 to 10, the battery pack fixing tool includes a tray 1, a support frame 2, and an adsorption assembly 3. The tray 1 has a first side and a second side which are oppositely arranged. The supporting frame 2 is fixed on the first surface of the tray 1 to bear a battery pack 7; the support frame 2 comprises a staggered distribution of support beams dividing the first side of the tray 1 into a plurality of placement areas 20. The adsorption component 3 comprises a suction cup 31 and an air duct 32; the suction cup 31 is positioned in the placing area 20 and fixed on the first surface of the tray 1; the air duct 32 is connected to the suction cup 31 so that the suction cup 31 sucks the surface of the battery pack 7.

In this embodiment, the battery pack fixing tool mainly comprises a battery pack fixing tool including a tray 1, a support frame 2 and an adsorption assembly 3. The tray 1 is used to carry a support frame 2 and a suction assembly 3. The support frame 2 is used to carry a battery pack 7. The adsorption component 3 is used for adsorbing the surface of the battery pack 7 so as to fix the battery pack 7. For example, the tray 1 is formed in a plastic suction mode, and the whole bearing capacity of the tray 1 is improved.

In this embodiment, the tray 1 has a first face and a second face which are oppositely disposed. For example, the tray 1 is made of plastic materials, so that the density is low, the forming is convenient, and the transportation full load rate of the loading vehicle is improved. Specifically, under the condition that the loading weight of the loading vehicle is fixed, the lighter the tray 1 is, the larger the number of the loaded battery packs 7 is, and the transportation full load rate of the loading vehicle is improved.

In this embodiment, the support frame 2 is fixed to a first face of the tray 1. The support frame 2 is fixed to the first face of the tray 1 by fasteners, for example. The fasteners may be screws or the like. The support frame 2 is used for carrying the battery pack 7, for example, the support frame 2 may form a carrying surface larger than the surface area of the battery pack 7, so as to facilitate the placement of the battery pack 7 on the support frame 2.

The support frame 2 comprises support beams in a staggered distribution. The support frame 2 comprises, for example, a plurality of cross beams 21b and a plurality of longitudinal beams 21 a. The plurality of cross beams 21b and the plurality of longitudinal beams 21a are arranged in a crisscross manner, so that the overall structural stability of the support frame 2 is improved. In this embodiment, the support frame 2 supports the battery pack 7 such that the battery pack 7 is spaced from the tray 1 to facilitate lifting of the battery pack 7.

In this embodiment, since the supporting frame 2 comprises supporting beams in a staggered distribution, the supporting beams can divide the first side of the tray 1 into a plurality of placing areas 20. For example, referring to fig. 2, the support frame 2 divides the first side of the tray 1 into 15 placement areas 20.

In this embodiment, the adsorption assembly 3 includes a suction cup 31 and a vent pipe 32. Wherein the suction cup 31 is located in the placing area 20 and is fixed on the first side of the pallet 1 by means of fasteners. For example, the fasteners may be screws or the like.

In this embodiment, the air duct 32 is connected to the suction cup 31. One end of the air duct 32 is connected to the suction cup 31, and the other end of the air duct 32 is connected to a vacuum generating device. When the vacuum generator is activated, air is introduced into the suction cup 31 through the air duct 32, and the air in the suction cup 31 is drawn out, thereby forming a vacuum state with a pressure P2. At this time, the air pressure inside the suction cup 31 is lower than the atmospheric pressure P1 outside the suction cup 31, i.e., P2< P1, and the battery pack 7 is sucked up by the pressure. The higher the degree of vacuum inside the suction cup 31 is, the greater the suction force of the suction cup 31 to the battery pack 7 is. For example, the vacuum principle is adopted by the air pressure difference of the suction cup 31, so that the three directional degrees of freedom of the suction cup 31 are limited by increasing the adsorption force, and the stability of fixing the battery pack 7 is improved. For example, suction cup 31 is a vacuum cup 31.

When the ventilation pipeline 32 stops ventilating into the suction cup 31, the adsorption acting force of the suction cup 31 on the surface of the battery pack 7 is reduced until the suction cup 31 does not have the adsorption acting force on the surface of the battery pack 7, and at the moment, the battery pack 7 can be detached from the battery pack fixing tool. The embodiment of the utility model provides a frock is fixed to battery package has made things convenient for the fixed and dismantlement to battery package 7. In addition the embodiment of the utility model provides a fixed frock of battery package can cyclic utilization.

In this embodiment, because the suction cup 31 is placed in the placement area 20, when the suction cup 31 exerts an adsorption force on the battery pack 7, the support frame 2 has a limiting effect on the battery pack 7 and the suction cup 31, and the phenomenon that the suction cup 31 damages the surface of the battery pack 7 due to an excessively large adsorption force on the surface of the battery pack 7 can be avoided.

In the present embodiment, the battery pack 7 is fixed by sucking the surface of the battery pack 7 by the suction action of the suction cup 31.
