[0023] In this embodiment, the principle of vacuum formation is: the battery is plugged into an acid pot with acid pre-filled, the battery is placed on a battery tray, the internal charging wires between the batteries are connected, and the entire tray of batteries is placed in a vacuum device. When the vacuum device is full of battery trays, the vacuum device is started, and the external connection terminals of the charger automatically contact and press with the graphite connector 4 on the battery tray under the action of the vacuum air bag.
[0024] The graphite joint 4 is used to replace the copper part, which has good corrosion resistance, can avoid the corrosion of the copper part by acid mist, and prolong the service life.
[0025] In order to make the graphite joint 4 reliable, Figure 2 As shown, the graphite joint 4 includes an outer end 5 and an inner end 6, the outer end 5 is arranged on the outer side of the end plate 3, the end plate 3 is provided with a through mounting hole 7, and the inner end 6 is penetrated through the mounting hole 7. In this embodiment, the outermost side of the inner end 6 is flush with the mounting hole 7. The outer end 5 is arranged on the outer side of the end plate 3 to facilitate connection with the external terminal of the charger; the inner end 6 is penetrated through the mounting hole 7 to facilitate connection with the battery pack inside the end plate 3 through a wire.
[0026] In order to ensure reliable connection, the outer end 5 is a round end face and the inner end 6 is a cylinder; the diameter of the outer end 5 is larger than the diameter of the inner end 6. The outer end 5 is a round end face with a large area, which is convenient for connection with the external terminal of the charger, and the inner end 6 is a cylinder, which is convenient for passing through the mounting hole 7.
[0027] In order to ensure reliable wire connection, Figure 3 As shown, the inner end 6 is provided with a threaded hole 8, and the threaded hole 8 is used to connect the wire; the threaded hole 8 is arranged on the end surface of the inner end 6 facing the inner side of the tray body 1; the opening of the threaded hole 8 faces the inner side of the tray body 1. The design of the threaded hole 8 allows the wire to be tightened with a screw after being inserted into the threaded hole 8, so as to prevent the wire from coming out, and facilitate the connection of the wire to the battery pack with a screw; the threaded hole 8 faces the inner side of the tray body 1, which is convenient for connection with the wire.
[0028] For reliable structure, the tray body 1 is a rectangular box-shaped structure with an open top, and the end plates 3 include left and right end plates 9 and front and rear end plates 10; the graphite joints 4 are arranged on the left and right end plates 9. The rectangular box-shaped structure is easy to process and form.
[0029] In order to facilitate wiring, an inner plate 11 is provided on the bottom plate 2, and the outer side of the inner plate 11 is connected to the inner side of the left and right end plates 9. The design of the inner plate 11 creates a gap between the battery and the graphite joint 4, which can facilitate the wiring between the battery pack and the graphite joint 4, and can also facilitate the heat dissipation of the battery pack, and at the same time can improve the structural strength of the left and right end plates 9.
[0030] In order to improve the connection strength, the front and rear ends of the inner plate 11 are connected to the front and rear end plates 10; the bottom surface of the inner plate 11 is connected to the bottom plate 2. The top surface of the inner plate 11 is lower than the mounting hole 7, does not block the position of the graphite joint 4, and is convenient for wiring. The inner plate 11 is connected to the front and rear end plates 10, which can ensure the connection strength of the inner plate 11 and improve the overall structural strength of the tray body 1; the inner plate 11 is connected to the bottom plate 2, which can ensure the connection strength of the inner plate 11 and improve the overall structural strength of the tray body 1.

The design of the second support plate 13 can improve the stability of the support, prevent one of the first support plates 12 from being worn or damaged, resulting in tilted placement or easy shaking, and at the same time can improve the support force of the middle part of the bottom plate 2, prevent the middle part of the bottom plate 2 from being bent by the battery, and the second support plate 13 separates the two first support plates 12, so that the two plug plates of the forklift can extend into the two sides of the second support plate 13 respectively, balance the lifting force on both sides, and ensure that the forklift lifts the battery tray smoothly.
[0033] In order to prevent the acid mist generated during the formation process from corroding the tray, the bottom plate 2, the end plate 3, the inner plate 11, the first support plate 12 and the second support plate 13 are all made of engineering plastics; the bottom plate 2, the end plate 3, the inner plate 11, the first support plate 12 and the second support plate 13 are all welded together. High-strength engineering plastics are used, which have strong corrosion resistance, light weight and good impact resistance; they are welded together as a whole, with high structural strength and good sealing.
