"Inner, outer" refers to the inner and outer contours of the corresponding components. In addition, it should be noted that the terms such as "first, second" are used to distinguish one element from another element, and do not have sequential and important meanings. In addition, in the description with reference to the drawings, the same reference signs in different drawings represent the same elements. The above definitions are only used to explain and illustrate the present disclosure, and should not be understood as limiting the present disclosure.

[0035] The present disclosure relates to an electric core infiltrating device, which can more efficiently heat the electric core, thereby saving energy and improving the infiltration effect. Referring to Figure 1 and Figure 3The battery cell infiltration device of the present disclosure comprises a bearing support 1 and a heating assembly 2. The bearing support 1 is provided with a plurality of placement plates 11, which are arranged at intervals. The interval part is used for placing a battery cell. A plurality of battery cell mounting positions 2 are arranged on the first plate surface of the placement plate 11. When the battery cell infiltration device is used, the battery cell can be placed on the battery cell mounting position 12 for heating. The heating assembly 2 is connected to the placement plate 11 and can heat the battery cell mounting position 12. The battery cell infiltration device of the present disclosure can directly heat the placement plate 11 by the heating assembly 12 when in use. Compared with the traditional battery cell infiltration device which heats by convection heat transfer, the heat transfer efficiency is better, thereby reducing the waste of energy.

[0036] In an embodiment of the present disclosure, referring to Figure 3 and Figure 4 The heating assembly 2 comprises a first heating film 21, which covers the first plate surface of the placement plate 11. The battery cell mounting position 12 is also formed on the first heating film 21, so that the bottom surface of the battery cell placed in the battery cell mounting position 12 can directly contact the first heating film 21. By arranging the first heating film 21, the bottom surface of the battery cell can be directly heated by the first heating film 21 when the battery cell is heated, thereby maximizing the use of the heat generated by the first heating film 21 to improve the energy utilization rate and the heating efficiency of the battery cell.

[0037] In an embodiment of the present disclosure, referring to Figure 3 and Figure 4 The heating assembly 2 further comprises a plurality of first limiting members 23, which are arranged at intervals on the first heating film 21. The gap between the adjacent two first limiting members 23 forms the battery cell mounting position 12, so that the movement of the battery cell is limited after being placed in the battery cell mounting position 12. In this embodiment, the first limiting member 23 can be a strip-shaped body arranged on the first heating film 21. The strip-shaped bodies arranged at intervals form a rectangular battery cell mounting position 12. The shape of the battery cell and the battery cell mounting position 12 is also a rectangular box body. After being placed in the battery cell mounting position 12, the two sides of the battery cell can be limited by the strip-shaped body, avoiding the left and right movement of the battery cell, which affects the heating effect. Of course, in other embodiments, the shape of the first limiting member 23 and the battery cell can also be other types, which can be determined according to the actual situation, and the present disclosure does not limit this.

[0038] In an embodiment of the present disclosure, referring to Figure 5 and Figure 6The heating assembly 2 further comprises a second heating film 22 covering the second plate surface of the placement plate 11 opposite to the first plate surface, and the second heating film 22 is in contact with the top surface of the battery cell. By arranging the second heating film 22, the top surface and the bottom surface of the battery cell can be heated simultaneously by the first heating film 21 and the second heating film 22 when the battery cell is heated, thereby improving the heating efficiency of the battery cell and more uniformly heating the battery cell.

[0039] In an embodiment of the present disclosure, the first heating film 21 and the second heating film 22 are both made of compressible material. In this way, the spacing between the first heating film 21 and the second heating film 22 can be slightly smaller than the thickness of the battery cell, so that the battery cell can press the first heating film 21 and the second heating film 22 after being placed in the battery cell mounting position 12, thereby enabling the battery cell and the heating film to be in closer contact. On the one hand, the movement of the battery cell on the heating film can be further limited, and on the other hand, the heating effect of the heating film on the battery cell can be improved.

[0040] In an embodiment of the present disclosure, referring to Figure 4 and Figure 6 , a heat insulation layer 24 is arranged between the first heating film 21 and the first plate surface of the placement plate 11, and between the second heating film 22 and the second plate surface of the placement plate 11. By arranging the heat insulation layer 24, the thermal resistance between the heating film and the placement plate 11 can be increased, thereby preventing the heat generated by the heating film from being transferred to the placement plate 11, so as to increase the heat transfer efficiency between the heating film and the battery cell.

[0041] In an embodiment of the present disclosure, referring to Figure 3 and Figure 4 , the bearing bracket 1 further comprises a heat preservation shell 13 with an opening on one side, and a plurality of placement plates 11 can be arranged in the heat preservation shell 13 in parallel and spaced apart in the vertical direction along the horizontal direction. When placing the battery cell, the battery cell can be placed on different battery cell mounting positions 12 through the opening on the heat preservation shell 13. By arranging the heat preservation shell 13, the heat loss of the heating assembly 2 can be avoided, and the inside of the heat preservation shell 13 can be kept at a high temperature for heating the battery cell, thereby improving the efficiency of heating the battery cell.

[0042] In an embodiment of the present disclosure, referring to Figure 1 and Figure 2The battery cell infiltration device of the present disclosure further comprises a rotating assembly 3. Due to the problem of electrolyte settlement in the battery cell during heating, the electrolyte will cause insufficient infiltration of the upper part of the battery cell after settlement. The rotating assembly 3 can drive the bearing bracket 1 to rotate, so that the battery cell in the bearing bracket 1 changes position, and the electrolyte flows in the battery cell to avoid the settlement problem. In some embodiments of the present disclosure, the rotating assembly 3 drives the bearing bracket 1 to rotate to invert the battery cell therein, so that the electrolyte originally at the bottom of the battery cell flows to the top of the battery cell under the action of gravity, thereby enabling the rotated battery cell to be fully infiltrated by the electrolyte, and the problem of insufficient infiltration of the upper part of the battery cell due to electrolyte settlement is avoided.

[0043] In an embodiment of the present disclosure, referring to Figure 1 and Figure 2 The second limiting piece 111 is further arranged on the placement plate 11. The second limiting piece 111 can limit the movement of the battery cell during the rotation of the bearing bracket 1 driven by the rotating assembly 3, so as to avoid the battery cell from being separated from the battery cell mounting position 12. The position and number of the second limiting piece 111 can be determined according to the direction and angle of the rotation of the bearing bracket 1 driven by the rotating assembly 3. For example, in some embodiments of the present disclosure, the rotating assembly 3 drives the bearing bracket 1 to rotate 180° along the central axis thereof to invert the battery cell therein. The placement plate 11 is rectangular, and the second limiting piece 111 can be a strip-shaped body with the same length as the placement plate 11 and arranged at the end of the placement plate 11, so as to prevent the battery cell from falling off the bottom of the placement plate 11 during the rotation of the bearing bracket 1 driven by the rotating assembly 3. Of course, in other embodiments, the second limiting piece 111 can also be of other types, for example, the second limiting piece 111 can be arranged on both sides of the placement plate 11, which can be determined according to the actual situation, and the present disclosure does not limit this.

[0044] In an embodiment of the present disclosure, referring to Figure 1 and Figure 2 The rotating assembly 3 comprises a sleeve 31 and an annular track 32. The sleeve 31 is used to place the bearing bracket 1. When placing, the bearing bracket 1 needs to be pushed into the sleeve 31 from the opening on one side of the sleeve 31. The annular track 32 is sleeved outside the sleeve 31, and the central axis of the sleeve 31 coincides with the central axis of the annular track 32 and can rotate along the axis thereof relative to the annular track 32, so as to invert the battery cell on the bearing bracket 1 in the sleeve 31 after rotation. In some embodiments of the present disclosure, the bearing bracket 1 is a rectangular body, and the sleeve 31 is a rectangular shell. Pulleys are arranged at the four corners of the sleeve 31, and the sleeve 31 can rotate on the annular track 32 through the pulleys. Of course, in other embodiments, the connection mode between the sleeve 31 and the bearing bracket 1 and the annular track 32 can also be of other types, which will not be described in detail here.

[0045] In one embodiment of the present disclosure, referring to Figure 1 and Figure 2 , the annular tracks 32 are provided in plurality, are arranged at intervals along the extension direction of the sleeve 31, and are fixedly connected between the plurality of annular tracks 32 through the connecting beams 33 and are fixedly connected at the bottom to the base 34. By arranging the plurality of annular tracks 32 at intervals along the extension direction of the sleeve 31 and connecting each annular track 32 to the sleeve 31, more support can be provided for the sleeve 31 to ensure the stability of the sleeve 31 during rotation and to avoid the sleeve 31 from falling off the annular track 32 during rotation, and the connecting beams 33 can ensure support between the annular tracks 32 to ensure the stability of the annular tracks 32 on the base 34.

[0046] In one embodiment of the present disclosure, referring to Figure 1 and Figure 2 , the rotating assembly 3 further comprises a power member 35, which is detachably connected to the carrying support 1 to drive the sleeve 31 to rotate along its own axis relative to the annular track 32 and to the inverted position of the battery cell in the carrying support 1. The detachable connection of the power member 35 to the carrying support 1 can be assembled only when the carrying support 1 needs to be rotated, and can not be assembled when it does not need to be rotated, so as to avoid the power member 35 from affecting the carrying of the annular track 32 and the base 34. Of course, in other embodiments, the power member 35 can also not be provided, and the sleeve 31 can be rotated by the staff, which will not be described in more detail here.

[0047] In one embodiment of the present disclosure, referring to Figure 1 and Figure 2 , a plurality of balls 311 are arranged on the inner wall of the sleeve 31. The balls 311 can assist the staff when placing the carrying support 1 into the sleeve 31. When placed, the carrying support 1 will come into contact with the balls 311 on the inner wall of the sleeve 31, and as the carrying support 1 continuously moves into the sleeve 31, the balls 311 will also rotate synchronously to reduce the force required by the staff to place the carrying support 1 into the sleeve 31.

[0048] When the battery cell infiltration device of the present disclosure is used, the installation of the battery cell is required first, the plurality of battery cells are placed from the opening of the heat preservation shell 13 onto the plurality of battery cell installation positions 12 on the placement plate 11, then the carrying support 1 is placed into the sleeve 31 and the power member 35 is installed to the carrying support 1, and finally the first heating film 21 and the second heating film 22 are started to heat the battery cell. In the heating process, in order to prevent the battery cell from electrolyte settlement, the power member 35 can also be started to drive the carrying support 1 to rotate, so that the battery cell in the carrying support 1 can be rotated to the inverted position.
