In some embodiments of the present invention, as shown in fig. 5, a first through hole 102b is formed on the heating component 102, and the positioning portion 101 is disposed in the first through hole 102b and partially protrudes from the inner side surface of the heating component 102. The shape of the first via hole 102b may be the same as that of the positioning portion 101, and reference may be made to the foregoing specifically, which is not described herein again. In this way, positioning portion 101 completely penetrates through heating member 102, so that the bonding surface of positioning portion 101 and heating member 102 is larger, and the connection reliability of positioning portion 101 and heating member 102 is better.

The heating body 1021 may refer to a portion of the heating part 102 that releases a heat source. The flexible heat conducting part 1022 is a high temperature resistant flexible heat conducting part, for example, a heat conducting silica gel pad, a heat conducting rubber pad, etc. since the flexible heat conducting part 1022 has a certain compression amount, it can be better attached to the side plate 210, and the combination with the side plate 210 is tighter, so that the heat on the heating body 1021 is better transferred to the side plate 210, and the side plate 210 is heated more uniformly.

It can be understood that, the flexible heat conducting portion 1022 can make the heating member 102 and the side plate 210 make soft contact, and in addition, the plurality of positioning portions 101 can play a positioning role, that is, can have heating and positioning roles at the station of standing still simultaneously, and the side plate 210 is heated more uniformly, and the positioning point is more, and the positioning is more accurate, so that the glue curing effect of the battery 200 can be improved.

In some embodiments of the present invention, as shown in fig. 6, the flexible heat conducting portion 1022 has a contact surface 1022a disposed near the positioning space, the positioning portion 101 has a positioning surface 101a disposed near the positioning space, and the area of the contact surface 1022a is larger than the sum of the areas of the plurality of positioning surfaces 101 a. The contact surface 1022a may refer to a surface of the flexible heat conduction portion 1022 contacting the side plate 210, and the positioning surface 101a may refer to a surface of the positioning portion 101 contacting the side plate 210 and performing a positioning function. The area of the contact surface 1022a is larger than the sum of the areas of the positioning surfaces 101a, so that the heat generated by the heating component 102 can be transmitted to the side plate 210 more quickly by the larger contact surface 1022a while the positioning effect is achieved, the heating speed of the side plate 210 is higher, and the glue curing effect is favorably improved.

In some embodiments of the present invention, as shown in fig. 2, the circumferential edge of the flexible thermal conductor 1022 around the second direction and the circumferential edge of the heating body 1021 around the second direction are flush. For example, the second direction may refer to a left-right direction, i.e., a width direction of the battery 200, and thus, "circumferential edges of the flexible heat conductive part 1022 around the second direction" may refer to front, rear, upper, and lower edges of the flexible heat conductive part 1022, and likewise, "circumferential edges of the heating body 1021 around the second direction" may refer to front, rear, upper, and lower edges of the heating body 1021. In this way, the shape of the flexible heat conduction part 1022 and the heating main body 1021 is consistent, the integrity is better, and the surface area of the flexible heat conduction part 1022 and the surface area of one side of the heating main body 1021 are equal, so that the heat generated by the heating main body 1021 can be quickly conducted.

For example, the heating body 1021 is a rectangular block, and the flexible heat conduction portion 1022 is a rectangular heat conduction pad having a small thickness.

Specifically, the heating body 1021 extends in the first direction, and a length of the heating body 1021 in the first direction and a length of the side plate 210 are substantially equal. That is, the length of the heating body 1021 may be equal to the length of the side plate 210, or both sides of the heating body 1021 in the longitudinal direction may be adjacent to both sides of the side plate 210 in the longitudinal direction, so that the flexible heat conducting portion 1022 and the side plate 210 have a relatively large contact surface 1022a therebetween, thereby providing a relatively good heating effect to the side plate 210.

In some embodiments of the present invention, as shown in fig. 6, a second through hole 1022b is provided on the flexible heat conducting portion 1022, and a portion of the positioning portion 101 close to the positioning space is provided in the second through hole 1022 b. When the side plate 210 of the battery 200 is positioned, as the body approaches the side plate 210, the flexible heat conduction portion 1022 first contacts the side plate 210 and is compressed, and the positioning portion 101 can be stopped on the side plate 210 through the second through hole 1022b, and the second through hole 1022b can prevent the flexible heat conduction portion 1022 from affecting the positioning of the positioning portion 101. In this way, the positioning portions 101 and the flexible heat-conducting portions 1022 can be arranged in a concentrated manner, and the side plate positioning assembly 10 is compact in structure and can save space.

Specifically, as shown in fig. 4 and 7, the second vias 1022b and the positioning portions 101 are equal in number and correspond to each other one by one, for example, the number of the second vias 1022b is six, the number of the positioning portions 101 is six, and one positioning portion 101 is disposed in each second via 1022 b. Of course, this is merely an example, the number of the second vias 1022b and the positioning portion 101 is not limited to this, and may also be other numerical values, and may be specifically set according to needs, and is not described here any more.

In some embodiments of the present invention, as shown in fig. 6 and 8, a positioning surface 101a is formed on a portion of the positioning portion 101 located in the second via hole 1022b, the flexible heat conducting portion 1022 has a contact surface 1022a disposed close to the positioning space, a compression gap 10b is formed between the positioning surface 101a and the contact surface 1022a, and the compression gap 10b is smaller than 1mm. The "compression gap 10b" may refer to a compression amount generated by the flexible heat conducting portion 1022 when the positioning surface 101a contacts the side plate 210, and the compression gap 10b is smaller than 1mm, which not only allows the flexible heat conducting portion 1022 to flexibly contact the side plate 210, but also allows the flexible heat conducting portion 1022 to have a certain rigidity, and may provide a supporting and stabilizing effect for the side plate 210.

In some embodiments of the present invention, the thickness of the flexible heat conducting part 1022 may be 4 to 6mm. For example, the thickness of the flexible heat conduction portion 1022 is any of 4mm, 5mm, and 6mm. Of course, the thickness of the flexible thermal conductor 1022 is not limited to the above value, and may be a value in the range of 4 to 6mm, which is not described in detail herein.

In some embodiments of the present invention, as shown in fig. 8, the positioning portion 101 includes a positioning main body 1013 and a plurality of spacers 1014, the spacers 1014 are disposed in a stacked manner, the plurality of spacers 1014 are disposed at an end of the positioning main body 1013 away from the flexible heat conducting portion 1022, and the number of the plurality of spacers 1014 is adjustable to adjust a protruding length of the positioning main body 1013 on an inner side surface of the heating member 102. The positioning body 1013 may refer to a component of the positioning part 101, such as a positioning block or a positioning column. Gasket 1014 may be referred to as a sheet-like sheet material and gasket 1014 may be shaped to conform to the shape of positioning body 1013 throughout. The protruding length of the positioning body 1013 on the inner side of the heating member 102 can be changed by adjusting the number of the spacers 1014 to adapt to the compression amount of the flexible heat conduction part 1022 by the adjustment side plate 210, and on the other hand, the positioning effect for different batteries 200 can be adapted.

For example, when the types of the batteries 200 are different, the sizes of the batteries may also be different, the contour deformation amount of the batteries 200 in the glue curing stage is different, the external moving component pushes the positioning portion 101 to press against the side plate 210 for positioning, in order to adapt to the batteries 200 of different types or sizes, it is troublesome to adjust the motion parameters of the external moving component, and by increasing or decreasing the spacers 1014, the side plate positioning assembly 10 can better adapt to different batteries 200 and improve the adaptability of the positioning device 100 under the condition that the motion parameters of the external moving component are not changed.

Specifically, positioning body 1013 may be a square block and shim 1014 may be a square shim. Positioning body 1013 may also be a cylinder and spacer 1014 may be a circular spacer. The shape of the positioning body 1013 and the gasket 1014 can be specifically configured as desired and will not be described in detail herein.
