Description

Technical Field

[0001] The utility model relates to a tray, in particular to a battery pack loading tray for a cabin. Background Art

[0002] When traditional battery packs are loaded into the cabin, a forklift is usually used for loading. However, when loading the bottommost battery pack, due to insufficient space, the forklift arm cannot reach in. The forklift can only lift the battery pack to the height of the battery rack for loading, and then the battery pack is manually pushed into the cabin. When loading into the cabin, because the battery pack is relatively heavy, usually the weight of a single battery pack can reach 700 kg, which makes the manual loading very time-consuming and laborious. Moreover, uneven force on both sides will cause the battery pack to tilt to one side, scratching the side of the battery pack. Therefore, the traditional method of pushing the battery pack not only has low loading efficiency, consumes a great deal of physical strength of workers, but also easily scratches the product and even has potential safety hazards. Content of the Utility Model

[0021] The following further elaborates on the utility model in detail in conjunction with the drawings and the specific embodiments.

[0022] The utility model discloses a battery pack loading tray, and the overall structure is arranged as shown in Figure 1 and Figure 2 , including two major structural parts: the tray chassis 1 and the unpowered roller 2;

[0023] Among them, the structure of the chassis bracket 1 is arranged as shown in Figure 1 , and 1 is composed of a square tube base 11 and roller positioning rods 12 fixed on both sides in the length direction of the square tube base 11;

[0024] The square tube base 11 is formed by welding square tubes distributed in a crisscross pattern. The roller installation rod 12 is welded and connected to the square tube base 11 to form the basic frame structure of the entire chassis bracket 1.

[0025] The roller installation rod 12 is mainly used for the rolling arrangement of the unpowered rollers 2. Roller positioning grooves 13 are provided on the roller installation rod 12 to ensure that the grooves on the roller installation rods 12 at both positions are aligned one by one. Thus, a set of roller positioning grooves 13 is used for the placement and installation of one unpowered roller 2. Correspondingly, as Figure 1 shown, multiple unpowered rollers 2 are provided, and the multiple unpowered rollers 2 are arranged in parallel. Specifically, the shaft rods at both ends of the unpowered roller 2 are respectively placed in the roller positioning grooves 13, and it is necessary to limit the shaft rods at both ends of the unpowered roller 2 within the roller positioning grooves 13 to ensure that the unpowered roller 2 can rotate but will not break away.

[0026] The shaft rods at both ends of the unpowered roller 2 can be locked and restricted by using the roller pressing plate 4 and the battery pack protection block 6 provided above the roller installation rod 12.

[0027] Both the roller pressing plate 4 and the battery pack protection block 6 are set by bolt locking. The battery pack protection block 6 realizes the protection of the side of the battery pack at both positions. The roller positioning grooves 13 without the battery pack protection block are locked and restricted by the roller pressing plate 4 to ensure that the shaft rods at both ends of the powered roller 2 in each roller positioning groove 13 are effectively locked and restricted.

[0028] Again, as Figure 1 shown, considering the bag throwing use requirements of this tray device, a bag throwing guide rod 3 is fixedly connected to the front end of the roller installation rod 12, and the bag throwing guide rod 3 is aligned with the cabin battery rack.

[0029] Tray lifting holes 14 are provided at both end positions of the roller installation rod 12, so that the tray lifting holes 14 are distributed at the four corners of the tray bottom frame 1. The reserved lifting holes at the four corners facilitate the overall lifting of the tray device.

[0030] Removable safety pins 7 are provided on the frame bodies at both ends in the width direction of the tray bottom frame 1. By providing pin installation holes 15 on the tray bottom frame 1, the insertion and removal of the safety pins 7 are satisfied. The safety pins 7 are distributed on both sides of the whole multiple unpowered rollers 2 to prevent the accidental sliding of the battery pack.

[0031] Adjustable feet 5 are installed below the tray bottom frame 1. The adjustable feet 5 can be specifically assembled on the square tube base 11. The setting of the adjustable feet 5 enables this tray device to be height-adjusted according to on-site requirements.

[0032] Thus, for the battery pack loading tray disclosed in the present utility model, by installing and fixing the unpowered rollers 2, the battery pack can slide back and forth on the tray. At the same time, the battery pack protection blocks 6 on both sides are made of POM material, which can avoid scratching the battery pack; the safety pins 7 at both ends can also prevent the battery pack from accidentally slipping off.

[0033] During use, as Figure 3 and Figure 4 shown, directly transport this tray device to the front of the energy storage cabin to be loaded with the battery pack by forklift or overhead crane. Align the tray with the battery rack of the cabin through the loading guide rod 3. Then, use the tray lifting hole 14 to lift the battery pack onto the tray, remove the hook, pull out the safety pin 7 on the tray, and then push the battery pack into the battery bracket to complete the loading. After pushing the battery pack to the end, move the loading tray to the next loading station for subsequent loading.

[0034] Compared with the traditional battery pack loading method, especially when loading the bottom layer, the battery pack can only be forcibly pushed into the battery rack from the forklift by manpower, which causes great physical loss to the staff. Moreover, during the loading process, the battery pack may be deformed and damaged. The present utility model specifically uses a tray with unpowered rollers during loading, converting the original sliding friction during battery pack loading into rolling friction, which is more labor-saving and efficient in completing the loading work, effectively solving the problems of low loading efficiency, time-consuming and laborious, affecting and damaging the battery pack, and even having potential safety hazards caused by traditional manual operations.

[0035] The above embodiments are not limitations on the present utility model, and the present utility model is not limited to the above examples. Changes, modifications, additions, or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model also fall within the protection scope of the present utility model.
