[0015] Figure 1 It is a structural schematic diagram of the airtight fixture for the battery pack tray in the utility model. DETAILED DESCRIPTION

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0017] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the utility model.

[0018] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0019] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0020] like Figure 1 As shown, a preferred embodiment of the utility model provides a battery pack tray airtight fixture tooling, including: an airtight fixture base 1, a fixture support mechanism 2, a sealing plate 3, an equal volume filler 4, and a pressing mechanism 6;

[0021] Among them, the sealing plate 3 is horizontally arranged on the airtight fixture base 1 through the fixture supporting mechanism 2, there are multiple equal-volume fillers 4, which are horizontally laid on the sealing plate 3, and the battery pack tray to be tested is buckled on one of the equal-volume fillers 4. The clamping mechanisms 6 are respectively arranged on the airtight fixture base 1 and arranged around the sealing plate 3. Each of the clamping mechanisms 6 corresponds to one equal-volume filler 4, and the battery pack tray to be tested on the equal-volume filler 4 is clamped.

[0022] In the above technical solution, one equal-volume filler 4 corresponds to one battery pack tray to be tested, and the battery pack tray to be tested is inverted on the corresponding equal-volume filler 4. In this way, the equal-volume filler can be used to accurately position each battery pack tray to be tested without the need for manual verification. After the battery pack tray to be tested is buckled on the equal-volume filler 4, the control 6-clamping mechanism can be used to quickly and evenly clamp it.

[0023] In another technical solution, there are multiple clamp support mechanisms 2 surrounding the sealing plate 3, which can provide uniform support for the sealing plate 3 and avoid uneven force.

[0024] In another technical solution, the clamping mechanism 6 has a bending arm that can be bent and driven, and the bending arm is used to clamp the battery pack tray to be tested.

[0025] In another technical solution, the equal volume filler 4 is made of buffer foam, which also plays a certain buffering and protective role on the battery pack tray to be tested.

[0026] Another technical solution further includes a positioning mechanism 5, and the positioning mechanism 5 has multiple members, each of which is close to the sealing plate 3 to position the sealing plate 3. The positioning mechanism includes a positioning pin and a positioning hole, and the sealing plate and the airtight fixture base are provided with a through positioning hole, and the positioning pin is inserted into the positioning hole to position the sealing plate.

[0027] The depth of the positioning hole is greater than the depth of the positioning pin. When the positioning pin is inserted into the positioning hole, the top end of the positioning pin is lower than the surface of the sealing plate to avoid the protrusion of the positioning pin affecting the use of the fixture.

[0028] In another technical solution, the clamping mechanism 6 has a pressing head, and a non-slip pad is provided at the contact portion between the pressing head and the battery pack tray to be tested, so that the clamping and stabilizing effect is better.

[0029] In another technical solution, the shape and size of the equal-volume filler are adapted to the structure of the battery pack tray to be tested, and there is a certain distance between two adjacent equal-volume fillers so that the battery pack tray to be tested can be inverted on the corresponding equal-volume filler, and the distance between two adjacent equal-volume fillers is slightly larger than the sum of the thicknesses of the side walls of the two battery pack trays to be tested, so as to ensure that the two battery pack trays to be tested do not interfere with each other when they are inverted.

[0030] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
