[0036] Please refer to Figure 1 and Figure 2 , Figure 1 which is an exploded view of the fixing tooling 100 provided by the embodiment of the present utility model; Figure 2 which is an exploded view of the fixing system 400 provided by the embodiment of the present utility model from the first perspective.
[0037] The embodiment of the present utility model provides a fixing system 400, which includes a fixing tooling 100, a battery pack housing 200, and a dispensing machine 300. The fixing tooling 100 includes a magnetic member 110 and a tooling heating wire 120, and the magnetic member 110 is connected to the tooling heating wire 120. The fixing tooling 100 is placed inside the battery pack housing 200, wherein the magnetic member 110 magnetically attracts to the inner wall of the battery pack. Specifically, the magnetic member 110 magnetically attracts to the inner side of the bottom plate of the battery pack.
[0038] It should be noted that the battery pack housing 200 is made of a metal material, and the magnetic member 110 has magnetism. Therefore, when the magnetic member 110 approaches the battery pack housing 200, there is a magnetic attraction force between the magnetic member 110 and the battery pack housing 200.
[0039] Moreover, a battery pack heating wire 220 is provided on the inner wall of the battery pack housing 200. Thus, through the magnetic attraction force between the magnetic member 110 and the battery pack housing 200, the magnetic member 110 presses the battery pack heating wire 220, so that the battery pack heating wire 220 is fixed between the magnetic member 110 and the battery pack housing 200, thereby preventing the battery pack heating wire 220 from detaching.
[0040] It should be noted that, in this embodiment, the battery pack heating wire 220 is made of a copper-nickel alloy material. Therefore, there is no magnetic attraction force between the battery pack heating wire 220 and the magnetic member 110.
[0041] An adhesive is provided on the inner wall of the battery pack housing 200. The fixing tool 100 heats the adhesive by means of the tool heating wire 120 to make it solidify. In this embodiment, the adhesive is glue.
[0042] Specifically, after the magnetic member 110 is magnetically attracted to the battery pack housing 200, the dispenser 300 applies glue to the position where the battery pack heating wire 220 is located, that is, adds glue to the inner wall of the battery pack housing 200. After the glue application is completed, the tool heating wire 120 is powered on, thereby generating heat and heating the glue to make it solidify. Thus, the solidified glue is transformed into a glue layer, which can improve the heat conduction effect and ensure the temperature balance of the battery module during the process of heating the battery module by the battery pack heating wire 220.
[0043] It should be noted that after the glue solidifies, its adhesion force will decrease. Moreover, since the battery pack housing 200 and the magnetic member 110 are separated by the glue layer, the magnetic attraction force will also decrease. Therefore, the fixing tool 100 can be easily removed from the battery pack housing 200. Subsequently, other structures such as the battery module are fixed, thereby completing the fixing of the entire package.
[0044] It can be understood that the magnetic member 110 is located between the tool heating wire 120 and the battery pack housing 200. In addition, both the tool heating wire 120 and the battery pack housing 200 are conductive. To avoid short-circuit phenomena during the process of solidifying the glue and ensure safety, the magnetic member 110 has insulation properties. Therefore, the magnetic member 110 in this embodiment is a magnetic insulating member 114.
[0045] Furthermore, please refer to Figures 1 - 4 , Figure 3 is a schematic structural diagram of the magnetic insulating member 114 provided by the embodiment of the present invention; Figure 3 is a schematic structural diagram of the fixing system 400 from a second perspective provided by the embodiment of the present invention; Figure 4 is Figure 3Partial enlarged view at position A in the figure. In this embodiment, the magnetic insulating member 114 is provided with a plurality of through holes 111 arranged in an array. After the magnetic insulating member 114 is magnetically attracted to the inner wall of the battery pack housing 200, the dispenser 300 can apply glue to the battery pack heating wire 220 located on the inner wall of the battery pack housing 200 through the through holes 111.
[0046] According to the above content, it can be understood that the magnetic insulating member 114 is in a mesh shape. It should be noted that in this embodiment, since the battery pack housing 200 is rectangular, the mesh-shaped magnetic insulating member 114 is rectangular, that is, the plurality of through holes 111 are arranged in a linear array. In other embodiments, the mesh-shaped magnetic insulating member 114 can also be circular, that is, the plurality of through holes 111 are arranged in a circumferential array.
[0047] In this embodiment, the tooling heating wire 120 extends in a bent manner, and the extending direction of the tooling heating wire 120 is perpendicular to the axial direction of the through holes 111. Specifically, the tooling heating wire 120 is arranged in a serpentine shape along the extending direction of the wire of the mesh-shaped magnetic insulating member 114, so as to increase the contact area between the tooling heating wire 120 and the glue, and further improve the efficiency of glue solidification.
[0048] Furthermore, please refer to Figures 1 - 5 , Figure 5 which is a schematic cross-sectional view of the fixing tooling 100 provided by an embodiment of the present invention. In this embodiment, the magnetic insulating member 114 is located between the tooling heating wire 120 and the battery pack housing 200. It can be understood that the tooling heating wire 120 is welded to the upper surface of the magnetic insulating member 114.
[0049] In other embodiments, the tooling heating wire 120 and the magnetic insulating member 114 can also adopt other connection methods, such as: pasting.
[0050] In other embodiments, please refer to Figures 1 - 6 , Figure 6 which is a schematic cross-sectional view of the fixing tooling 100 provided by other embodiments of the present invention. The magnetic insulating member 114 can also be provided with a receiving groove 112, and the tooling heating wire 120 is received in the receiving groove 112. The glue adheres to the outer periphery of the magnetic insulating member 114, and the tooling heating wire 120 transfers heat to the glue through the magnetic insulating member 114, so that the glue solidifies.
[0051] It should be noted that in other embodiments, the magnetic insulating member 114 can be made by injection molding. Specifically, a plastic part is injection molded on the outer periphery of the tooling heating wire 120, and magnetic powder is added during the injection molding process to make the plastic part have magnetism, so as to obtain the magnetic insulating member 114 with magnetism and insulation. Thus, the magnetic insulating member 114 wraps the tooling heating wire 120.
[0052] In other embodiments, please refer to Figures 1 - 7 , Figure 7 which is a schematic structural diagram of the fixing tooling 100 provided in other embodiments of the present utility model. The magnetic insulating member 114 is provided with at least one buckle 113, and the tooling heating wire 120 is clamped to the buckle 113. When the tooling heating wire 120 is bent, the buckle 113 can be clamped to the bent portion of the tooling heating wire 120.
[0053] Furthermore, please refer to Figures 1 - 9 , Figure 8 which is a schematic structural diagram of the battery pack housing 200 provided in an embodiment of the present utility model; Figure 9 is Figure 8 a schematic structural diagram of the position B in
[0054] In this embodiment, a groove 210 is formed on the inner wall of the battery pack housing 200, and the battery pack heating wire 220 is accommodated in the groove 210. The battery pack heating wire 220 is used to heat the battery module. Thus, by arranging the battery pack heating wire 220 in the groove 210, the magnetic insulating member 114 can be tightly magnetically attracted to the inner wall of the battery pack housing 200, thereby pressing the battery pack heating wire 220 to fix the battery pack heating wire 220 and prevent it from detaching.
[0055] According to the above arrangement, in this embodiment, the battery pack housing 200 further includes a fixing member 230 which is connected to the battery pack housing 200; the fixing member 230 is used to fix the battery pack heating wire 220. Specifically, the groove 210 is bent on the battery pack housing 200. It can be understood that the battery pack heating wire 220 is bent to improve the heating efficiency of the battery pack heating wire 220 and enhance the heat conduction effect. Among them, the fixing member 230 is arranged at the bent portion of the groove 210 to fix the battery pack heating wire 220, improve the fixing effect and prevent the battery pack heating wire 220 from detaching.
[0056] In summary, an embodiment of the present utility model provides a fixing system 400, which includes a fixing tooling 100, a battery pack housing 200 and a dispensing machine 300. The fixing tool includes a magnetic insulating member 114 and a tooling heating wire 120. The fixing tool is placed inside the battery pack housing 200 and is magnetically attracted to the inner wall of the battery pack housing 200 by the magnetic insulating member 114. Thus, by using the magnetic attraction force between the magnetic insulating member 114 and the battery pack housing 200, the magnetic insulating member 114 can be adsorbed on the battery pack housing 200, thereby pressing the battery pack heating wire 220 located on the inner wall of the battery pack housing 200 to fix the battery pack heating wire 220 and prevent it from detaching.
[0057] Moreover, the magnetic insulator 114 is provided with through holes 111 which are in a mesh structure, so that the dispenser 300 can dispense glue on the battery pack heating wire 220 through the through holes 111. After the dispensing is completed, the glue is heated by the tooling heating wire 120 connected to the magnetic insulator 114, so that the glue solidifies, and then an adhesive layer is formed, improving the heat conduction effect of the battery pack heating wire 220 and ensuring the temperature balance of the battery module.
[0058] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various modifications and changes can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
