[0010] Main lining;

[0011] Side wing plates, which are symmetrically arranged on both sides of the main lining plate, and an angle is formed between the side wing plates and the main lining plate;

[0012] When the first elastic wing is installed into the gap between the battery slot partition and the pole group, deformation will occur between the main lining plate and the side wing plate so that the first elastic wing can adapt to the gap between the battery slot partition and the pole group.

[0013] In some embodiments, the liner body further includes

[0014] a second elastic wing;

[0015] A connecting part, one end of which is connected to the first elastic wing, and the other end of which is connected to the second elastic wing;

[0019] In some embodiments, a plurality of through holes are provided on the primary lining plate.

[0020] In some embodiments, the connecting portion comprises

[0021] An abutment plate, used to abut against the top of a battery slot partition wall in the battery slot;

[0038] In order to better understand the technical solution of the present utility model, the embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0039] It should be clear that the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0041] The cross-type fuse-type elastic liner is used to fill the gap between the battery slot partition and the pole group in the battery slot, so that the pole group and the battery slot can be tightly assembled, thereby improving the overall vibration resistance of the battery. Specifically, a large groove is provided in the battery slot, which is a roughly rectangular cavity. Multiple battery slot partitions divide the battery slot into multiple battery cells, each of which can accommodate a pole group, and the pole group is placed in the battery cell.

[0042] Embodiment 1

[0043] A cross-type fuse-type elastic liner for battery assembly, such as Figure 1-2 , combined Figure 5 As shown, it includes a liner body 1 and a connecting portion 2. The liner body 1 is used to fill the gap between the pole group 4 and the battery slot partition 31. The connecting portion 2 is provided on the liner body 1. The liner body 1 is bent with the connecting portion 2 as the middle point, and the liner body 1 is installed in the battery slot 3. Specifically, in this embodiment, the liner body 1 is symmetrically bent through the connecting portion 2, and then inserted into the adjacent battery cells 32 in the battery slot 3, and each end of the liner body 1 is respectively inserted into the gap between the pole group 4 and the battery slot partition 31. The connecting portion 2 can abut against the top of the battery slot partition 31 to assist in positioning the liner body 1.

[0044] like Figure 1-2 As shown, the liner body 1 includes a first elastic wing 11 and a second elastic wing 12, and the connecting portion 2 is connected between the first elastic wing 11 and the second elastic wing 12. Specifically, the first elastic wing 11 and the second elastic wing 12 are symmetrically bent with the connecting portion 2 as the midpoint. After each end of the liner body 1 is installed in the battery cell 32, the first elastic wing 11 and the second elastic wing 12 are respectively arranged between the pole group 4 and the battery slot partition 31. In this embodiment, the second elastic wing 12 and the first elastic wing 11 have the same structure.

[0045] like Figure 1-2As shown, further, the first elastic wing 11 includes a main lining plate 111 and a side wing plate 112, the side wing plates 112 are symmetrically arranged on both sides of the main lining plate 111, and abutment portions 114 are also provided on the side wing plates 112. Specifically, the first elastic wing 11 abuts between the pole group 4 and the battery slot partition 31, wherein the main lining plate 111 abuts against the pole group 4, and the abutment portions 114 on the side wing plates 112 abut against the battery slot partition 31, so that the pole group 4 will not shake in the battery slot 3. In this embodiment, the angle between the main lining plate 111 and the side wing plates 112 is 140°-160°, preferably 150°, as shown in FIG. Figure 3 as shown.

[0046] like Figure 4 As shown, since the gap between the battery slot partition 31 and the pole group 4 is large or small, the angle between the main lining plate 111 and the side wing plate 112 will change with the change of the gap size between the battery slot partition 31 and the pole group 4. When the first elastic wing 11 and the second elastic wing 12 are inserted into the gap between the battery slot partition 31 and the pole group 4, deformation will occur between the main lining plate 111 and the side wing plate 112 to adapt to the gap between the battery slot partition 31 and the pole group 4, and in the process of transporting or moving the battery, since elastic deformation will occur between the main lining plate 111 and the side wing plate 112, the first elastic wing 11 and the second elastic wing 12 can buffer the impact force generated when the pole group 4 moves and protect the pole group 4.

[0047] The main lining plate 111 is provided with a plurality of through holes 113. Specifically, the main lining plate 111 is provided with a plurality of through holes 113 arranged in a formation, which is used to reduce the weight of the main lining plate 111, and at the same time, when the main lining plate 111 is in contact with the pole group 4, it is beneficial to ventilate and dissipate heat of the pole group 4.

[0048] The connecting portion 2 includes an abutment plate 21, a first bending strip 22, and a second bending strip 23. The abutment plate 21 is used to abut against the top of the battery slot partition 31 in the battery slot 3. One end of the first bending strip 22 is connected to the abutment plate 21, and the other end thereof is connected to the first elastic wing 11. One end of the second bending strip 23 is connected to the abutment plate 21, and the other end thereof is connected to the first elastic wing 11. Specifically, the abutment plate 21 is roughly a rectangular plate. When the first elastic wing 11 and the first elastic wing 11 are connected and bent relative to the abutment plate 21, the first bending strip 22 and the second bending strip 23 are bent. The first bending strip 22 and the second bending strip 23 are slender connecting strips with strong toughness. In this embodiment, the first bending strip 22 and the second bending strip 23 are symmetrically arranged on both sides of the abutment plate 21. The thickness of the abutment plate is only 0.2mm, which will be melted during the heat sealing process of the battery slot 3 and the battery middle cover, and will not affect the heat sealing of the battery middle cover; wherein, the heat sealing process is the process of bonding the battery middle cover and the battery slot 3 together, specifically, using a hot plate to melt the heat sealing ribs of the battery slot 3 and the battery middle cover by 1mm respectively, and then pressing and bonding them together.

[0049] Embodiment 2

[0050] A cross-type fuse-type elastic liner for battery assembly includes a liner body 1, a first elastic wing 11, a second elastic wing 12, a main liner 111, a side wing plate 112, a connecting portion 2, an abutment plate 21, a first bending strip 22, a second bending strip 23 and other structures, and the above structure is the same as the structure described in Example 1.

[0051] like Figure 6 As shown, in this embodiment, the difference from the structure described in the first embodiment is that the first bending strip 22 and the second bending strip 23 are centrally symmetrically arranged on both sides of the abutting plate 21 .

[0052] The method of using the utility model is as follows: bend the two ends of the lining plate body from the middle connection part, and when assembling, hang the middle connection part of the lining plate body on the battery slot partition wall in the battery slot, and after the pole group is placed in the battery cell, it will squeeze the end of the lining plate body, and the elastic wing at the end of the lining plate body will provide a reaction force to the pole group, making it difficult for the pole group to shake, so as to achieve a tight assembly effect. The connection part hung on the battery slot partition wall will melt during the heat sealing process, and will not affect the heat sealing of the battery middle cover and the battery slot.

[0053] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
