DETAILED DESCRIPTION

[0032] Hereinafter, exemplary embodiments according to the present application will be described in detail with reference to the accompanying drawings. It should be apparent to those skilled in the art that the following described embodiments are merely exemplary of the application and should not be considered to narrow the scope of the present application as the present application is defined by the appended claims.

[0033] Figure 1 A structural diagram of a battery module according to an exemplary embodiment of the present application. Figure 2 An exploded diagram of a battery module according to an exemplary embodiment of the present application. As shown in FIG. 2, the battery module 300 includes a plurality of battery cells 400, a module bracket 100, a duct frame 110, and a wire harness plate 112.Figure 1 and Figure 2 As shown in

[0034] As shown in Figure 1 and Figure 2 The module support 100 can include an air duct support 110, which includes an air duct support body 111 and a wire harness plate 112. The air duct support body 111 is provided with a plurality of mounting cavities 1111, and the battery monomer 400 is assembled in the mounting cavities 1111. The wire harness plate 112 is connected to one end of the air duct support body 111. On the one hand, the wire harness plate 112 can protect the battery monomer 400. On the other hand, the wire harness plate 112 can be used to connect the pole 410 of the battery monomer 400, and the wire harness plate 112 and the pole 410 can transmit current signals.

[0035] Figure 3 The structure diagram of the mounting cavity provided by an exemplary embodiment of the present application is shown in Figures 1 to 3 As shown in Figure 3 The cross-sectional width of the mounting cavity 1111 gradually widens from one end close to the wire harness plate 112 to the other end away from the wire harness plate 112 (indicated by the arrow D in Figure 3 Thus, the battery monomer 400 can be directly assembled into the mounting cavity 1111 along the direction indicated by the arrow E in

[0036] It should be understood that the structure of the module support 100 provided by the embodiment of the present application is simple. When assembling the battery monomer 400, the battery monomer 400 is directly assembled into the mounting cavity 1111 from the end of the mounting cavity 1111 away from the wire harness plate 112, which can realize the function of quickly assembling the battery monomer 400 and effectively improve the work efficiency. Similarly, when disassembling the battery monomer 400, the battery monomer 400 is directly disassembled from the end of the mounting cavity 1111 away from the wire harness plate 112, which can realize the function of quickly disassembling the battery monomer 400 and effectively improve the work efficiency.

[0037] In an embodiment, the cross-sectional width of the mounting cavity 1111 gradually widens from one end close to the wire harness plate 112 to the other end away from the wire harness plate 112, which can be gradually widened in a straight line equation (fixed slope) or a parabolic equation (variable slope).

[0038] It should be noted that, since the battery monomer 400 is disassembled from the end away from the wire harness plate 112, the wire harness plate 112 does not need to be disassembled, so the air duct frame body 111 and the wire harness plate 112 can be considered to be integrally formed, which can simplify the connection structure between the air duct frame body 111 and the wire harness plate 112, and can improve the strength of the air duct frame 110 as a whole, and without the need to additionally install the wire harness plate 112, the overall production efficiency is improved.

[0039] As shown in Figure 1 , the wire harness plate 112 is provided with a through hole 1121, the through hole 1121 is communicated with the mounting cavity 1111, after the battery monomer 400 is assembled into the mounting cavity 1111, the pole 410 of the battery monomer 400 can be exposed through the through hole 1121, which is convenient for the pole 410 to be connected with other electrical components. The through hole 1121 can also achieve the pre-positioning of the battery monomer 400, prevent the battery monomer 400 from shifting during installation, and also prevent the battery monomer 400 from moving after installation.

[0040] In an embodiment, a plurality of battery monomers 400 can be assembled in the same mounting cavity 1111, the number of through holes 1121 communicated with the same mounting cavity 1111 is a plurality, each through hole 1121 corresponds to the pole 410 of the battery monomer 400 one by one, and each battery monomer 400 has two poles, then each battery monomer 400 corresponds to two through holes 1121. The arrangement of the through holes can be configured according to the electrical connection arrangement mode of different battery monomers 400.

[0041] As shown in Figure 1 and Figure 2 , the air duct frame 110 includes a plurality of spaced apart partitions 113, one end of the plurality of partitions 113 is connected with the wire harness plate 112, and the mounting cavity 1111 is formed between the two adjacent partitions 113. The partition 113 can be used to limit the installation of the battery monomer 400 and improve the assembly stability of the battery monomer 400.

[0042] In an embodiment, the plurality of partitions 113 can be integrally formed with the wire harness plate 112, so that the connection step between the partition 113 and the wire harness plate 112 can be omitted, such as the steps of bolt connection, or welding, or bonding, to improve the production efficiency.

[0043] Figure 4 The structure schematic diagram of the air duct frame body provided by an exemplary embodiment of the present application is shown in Figure 1 and Figure 4As shown, the partition plate 113 includes a first supporting portion 1131, a second supporting portion 1133, and a connecting portion 1132, the first supporting portion 1131 is connected with the wire harness plate 112, the connecting portion 1132 is connected between the first supporting portion 1131 and the second supporting portion 1133, and the second supporting portion 1133 is located at an end of the connecting portion 1132 away from the wire harness plate 112. The thicknesses of the first supporting portion 1131 and the second supporting portion 1133 are greater than the thickness of the connecting portion 1132, so that at least one side surface of the partition plate 113 can form a groove 1134.

[0044] It should be noted that when the battery monomer 400 is assembled into the mounting cavity 1111, part of the side wall of the battery monomer 400 can abut on the first supporting portion 1131 and the second supporting portion 1133, and another part of the side wall of the battery monomer 400 can form an air duct 500 with the groove 1134. That is, when the battery monomer 400 is assembled into the mounting cavity 1111, the first supporting portion 1131 and the second supporting portion 1133 hold and limit the battery monomer 400 to prevent the battery monomer 400 from loosening or falling out of the mounting cavity 1111; and the air duct 500 between the side wall of the battery monomer 400 and the groove 1134 can flow the cooling fluid, which can cool the battery monomer 400 to avoid the temperature of the battery monomer 400 being too high.

[0045] In addition, the groove 1134 can also provide a reserved space for the volume of the battery monomer 400 after swelling, so as to avoid a large extrusion force between the battery monomer 400 and the partition plate 113 after swelling, thereby causing the battery monomer 400 to be broken.

[0046] In an embodiment, one end of the connecting portion 1132 can be connected to the middle of the first supporting portion 1131 in the thickness direction, and the other end of the connecting portion 1132 can be connected to the middle of the second supporting portion 1133 in the thickness direction, so that the groove 1134 can be formed on the opposite sides of the partition plate 113, and the grooves 1134 on the opposite sides of the partition plate 113 can form the air duct 500 with the side walls of the adjacent two battery monomers 400, respectively.

[0047] In combination Figure 3 , the side walls of the first supporting portion 1131 and the second supporting portion 1133 are coplanar to form a first plane 200, and the first planes 200 of the two partition plates 113 forming the mounting cavity 1111 are relatively inclined, so that the cross-sectional width of the mounting cavity 1111 can be gradually increased from the end close to the wire harness plate 112 to the end away from the wire harness plate 112. Figure 3The installation cavity 1111 is gradually widened in the direction indicated by the arrow D, thereby facilitating guiding the battery monomer 400 into the installation cavity 1111 or out of the installation cavity 1111, facilitating disassembly and assembly of the battery monomer 400. Meanwhile, it can prevent the battery monomer 400 from being unable to be completely installed due to manufacturing tolerances. If the cross-sectional width of the installation cavity 1111 is too small, the battery monomer 400 cannot be installed into the installation cavity 1111, and if the cross-sectional width is too large, the battery monomer 400 is not firmly installed, affecting its reliability.

[0048] As shown in Figure 3 , the first plane 200 is provided with a chamfer 115 at the connection with the bottom surface of the harness plate 112. After the battery monomer 400 is assembled into the installation cavity 1111, the top of the battery monomer 400 abuts against the chamfer 115. On the one hand, the chamfer 115 can abut the battery monomer 400 more tightly, and on the other hand, the chamfer 115 can make a gap exist between the top wall of the battery monomer 400 and the harness plate 112, preventing the top wall of the battery monomer 400 from being scratched. At this time, the pole 410 of the battery monomer 400 passes through the gap to facilitate electrical connection between the poles 410 of adjacent battery monomers 400. The top surface of the pole 410 can be higher than the bottom surface of the through hole 1121 of the harness plate 112, thereby being exposed from the through hole 1121, realizing positioning and limiting of the battery monomer 400, and facilitating electrical connection between the poles 410.

[0049] As shown in Figure 3 , the minimum distance between the two opposite first planes 200 is L, and the width of the battery monomer 400 is H. The distance L and the width H should satisfy L

[0050] It should be understood that since the cross-sectional width of the installation cavity 1111 is gradually widened from the end close to the harness plate 112 to the end away from the harness plate 112, the minimum distance between the two opposite first planes 200 can be understood as the distance between the combination of the chamfer 115 and the first plane 200.

[0051] As shown in Figure 1 and Figure 2 , the module support 100 can further include a bottom plate 120, which is detachably connected with the second support portion 1133. In actual application, after the battery monomer 400 is assembled into the installation cavity 1111, the bottom plate 120 is assembled. The bottom plate 120 can be used to close the end of the installation cavity 1111 away from the harness plate 112, and the bottom plate 120 can serve as a carrier of the battery monomer 400, playing a role of bearing the battery monomer 400, and also preventing the battery monomer 400 from falling out of the installation cavity 1111.

[0052] Figure 5 As Figure 2 an enlarged schematic view at B. Figure 6 As Figure 4 an enlarged schematic view at C. As Figure 2 , Figure 4 , Figure 5 and Figure 6 shown, the second support portion 1133 is provided with a first connecting hole 1135, the bottom plate 120 is provided with a second connecting hole 121, and the module support 100 can further include a fastener (not labeled in the figure), which is detachably connected to the first connecting hole 1135 and the second connecting hole 121. In this way, the bottom plate 120 and the second support portion 1133 can be detachably connected, and the assembly and disassembly of the fastener are convenient, which can improve the disassembly efficiency of the bottom plate 120.

[0053] In an embodiment, the fastener can include a bolt, a screw, etc.

[0054] In actual application, the integrally formed air duct frame body 111 and the wire harness plate 112 can be inverted, and then the battery monomer 400 is loaded into the mounting cavity 1111 from the end away from the wire harness plate 112, and then the mounting bottom plate 120 is assembled. In this way, the battery monomer 400 is assembled from top to bottom under the assistance of gravity during assembly, which can facilitate assembly and effectively improve assembly efficiency.

[0055] As Figure 1 and Figure 2 shown, the module support 100 can further include a cable tie 130, which is arranged around the air duct frame body 111. After the battery monomer 400 is assembled into the mounting cavity 1111, the cable tie 130 is sleeved on the air duct frame body 111, and the cable tie 130 can clamp the battery monomer 400 in the mounting cavity 1111. In this way, the stability of the battery monomer 400 in the mounting cavity 1111 can be further improved, and damage to the battery monomer 400 due to shaking in the mounting cavity 1111 can be prevented. At the same time, the battery monomer 400 can also be prevented from falling out of the mounting cavity 1111.

[0056] As Figure 1 and Figure 2 shown, the number of cable ties 130 is two, and the two cable ties 130 are spaced apart and sleeved on the air duct frame body 111. One of the cable ties 130 is used to clamp the upper half of the battery monomer 400 (with the state of the battery monomer 400 shown in Figure 2 as a reference), and the other cable tie 130 is used to clamp the lower half of the battery monomer 400 (with the state of the battery monomer 400 shown in Figure 2 as a reference). In this way, the stability of the battery monomer 400 in the mounting cavity 1111 can be further improved.

[0057] It should be noted that in the case of two number of the cable tie 130, the two cable ties 130 are spaced and sleeved on the air duct frame body 111, one of the cable ties 130 is bound to the first support part 1131, and the other cable tie 130 is bound to the second support part 1133. Since the first support part 1131 and the second support part 1133 have a relatively thick thickness and a relatively high strength, after the two cable ties 130 are bound to the first support part 1131 and the second support part 1133 respectively, the deformation of the partition plate 113 can be prevented.

[0058] In an embodiment, the cable tie 130 can include a metal band, an insulating band, etc.

[0059] As shown in Figure 2 The outer wall of the air duct frame body 111 is provided with a clamping groove 114, and the cable tie 130 is clamped in the clamping groove 114. The clamping groove 114 can limit the cable tie 130, prevent the cable tie 130 from sliding relative to the air duct frame body 111, ensure that the cable tie 130 continuously clamps the battery monomer 400, and ensure that the battery monomer 400 is stably assembled in the mounting cavity 1111.

[0060] It should be understood that under the joint action of the cable tie 130 and the bottom plate 120, the assembly stability of the battery monomer 400 in the mounting cavity 1111 can be further improved.
