[0002] With the development of the electric vehicle industry, the use of electric vehicles is becoming more and more diversified. They may experience different working conditions and different environments, which makes the environmental adaptability of electric vehicles particularly important. Especially when electric vehicles are in tropical weather or weather with large temperature differences, because hot air is relatively light, it is mainly distributed above the battery pack. When the hot air is cooled, condensation is formed. Most of the condensation is concentrated on the inner surface of the upper shell. As it gathers, it will form droplets. If it drips directly on the output pole of the module, it will cause corrosion or directly cause a short circuit, resulting in abnormal collection. Therefore, it is particularly important to design a structure that effectively reduces the impact of condensation. Utility Model Content

[0040] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0041] Embodiment 1

[0042] The present embodiment relates to a mounting bracket assembly, which can guide condensed liquid droplets to flow to the outside of the module output pole 200, thereby effectively protecting the module output pole 200.

[0043] In terms of overall structure, see Figure 1 As shown, the mounting bracket assembly of this embodiment includes a bracket 11, and a protective cover 12 connected to the bracket 11. Among them, a harness mounting portion 112 is provided on the bracket 11, and the harness 1 mounted on the harness mounting portion 112 is connected to the module output pole 200. The protective cover 12 includes a cover body with a protrusion 120, and a shielding plate body 124 connected to the cover body, the shielding plate body 124 is used to shield the module output pole 200, the protrusion 120 extends along the connecting direction of the opposite ends of the cover body, and penetrates the opposite ends of the cover body, and at least the side of the protrusion 120 forms a guide portion, which is used to guide condensed liquid droplets to flow to the outside of the module output pole 200 in the direction pointing to the shielding plate body 124.

[0044] At this time, the protective cover 12, the protrusion 120 and the shielding plate body 124 arranged on the bracket 11 make the shielding plate body 124 shield the module output pole 200, and the side wall of the protrusion 120 forms a drainage portion to guide the condensed liquid droplets to flow to the outside of the module output pole 200 in the direction pointing to the shielding plate body 124, thereby effectively protecting the module output pole 200, and also helping to prevent the condensed liquid droplets from entering the plug-in to prevent corrosion. At the same time, the provision of the protrusion 120 is also conducive to improving the overall rigidity of the protective cover 12, preventing collapse, and also absorbing installation and manufacturing tolerances.

[0045] Based on the above overall structure, in detail, as a preferred implementation, in this embodiment, the raised portion 120 is located in the middle of the cover body, and the raised portion 120 is formed by arching from one side of the cover body to the other side, and in the extension direction, the raised portion 120 passes through from one end of the cover body to the other end of the cover body, which facilitates the processing and preparation of the raised portion 120.

[0046] See also Figure 4 and Figure 5 , and combined with Figure 1 As shown, in this embodiment, there are two shielding plate bodies 124 arranged symmetrically about the cover plate body, and the connecting line between the two shielding plate bodies 124 is orthogonal to the extension direction of the protrusion 120. The provision of two shielding plate bodies 124 can facilitate simultaneous protection of two adjacent output poles through one protective cover 12, and its structure is simple and highly integrated.

[0047] At this time, based on the arrangement of the two shielding plates 124, the overall structure of the protective cover 12 is in a cross shape. In addition, as a preferred implementation, in this embodiment, the protective cover 12 is preferably connected to the bracket 11 by bonding, which can facilitate the installation of the protective cover 12 and ensure the reliability of the connection between the protective cover 12 and the bracket 11.

[0048] It is understandable that, in addition to being connected to the bracket 11 by bonding, the protective cover 12 may also be connected to the bracket 11 by screwing or clamping, which is also feasible.

[0049] As a preferred implementation, in this embodiment, still refer to Figure 1 , Figure 4 and Figure 5 As shown, the cover body and the shielding plate body 124 are connected by a connecting plate body 123, and the connecting plate body 123 extends from the end of the cover body to a side away from the protrusion 120, and is arranged downwardly in a direction pointing to the bracket 11. The guide portion also includes the upper surface of the connecting plate body 123. The setting of the connecting plate body 123 is conducive to further guiding the condensed liquid droplets to flow to the outside of the module output pole 200, thereby further improving the anti-condensation effect of the module output pole 200.

[0050] Also as a preferred embodiment, in this embodiment, the shielding plate body 124 is arranged to be inclined downward in the direction pointing to the bracket 11 from the end close to the cover plate body to the end away from the cover plate body. The guide portion also includes the upper surface of the shielding plate body 124. The shielding plate body 124 is arranged to be inclined downward in the direction pointing to the bracket 11, which can further guide the condensed liquid droplets to flow to the outside of the module output pole 200, and further improve the anti-condensation effect of the module output pole 200.

[0051] See also Figure 5 As shown, as a preferred embodiment, the guide portion in this embodiment includes the side of the protrusion 120, the upper surface of the connecting plate body 123 and the upper surface of the shielding plate body 124, so that the condensation droplets can be better guided to flow in the direction pointing to the shielding plate body 124 to the outside of the module output pole 200.

[0052] Moreover, in a specific implementation, the angle α between the side of the protrusion 120 and the horizontal plane is preferably set between 45° and 60°, and the angle α can be set to 45°, 50°, 55° or 60°, etc. This is conducive to better outflow of condensed droplets. The connecting transverse plate 121 between the protrusion 120 and the connecting plate body 123 is a plane transition. The distance from the protrusion 120 to the connecting plate body 123 is large, so the angle needs to be designed for diversion. At this time, the angle β between the connecting plate body 123 and the horizontal plane is between 45° and 70°, and the angle β can be set to 45°, 50°, 55°, 60°, 65° or 70°, etc.

[0053] Since the connecting plate body 123 is directly connected to the shielding plate body 124, the condensed liquid droplets have a certain initial velocity after being guided by the connecting plate body 123. At this time, in order to save space in the overall height direction of the protective cover 12, the shielding plate body 124 can be set to be tilted downward in the direction pointing to the bracket 11 at a gentler angle. In specific implementation, the angle γ between the shielding plate body 124 and the horizontal plane is between 15°-30°. The angle γ can be set to 15°, 20°, 25° or 30°, etc. In actual use, the condensed liquid droplets flow along the side of the raised portion 120 to the connecting cross plate 121, then flow to the connecting plate body 123, and then flow to the shielding plate body 124, and flow from the shielding plate body 124 to the outside of the module output electrode.

[0054] It should be noted that, in addition to being connected to the shielding plate body 124 through the connecting plate body 123, the cover plate body can also be directly connected to the shielding plate body 124. In addition, in addition to being tilted downward in the direction pointing to the bracket 11, the shielding plate body 124 can also be arranged horizontally. In this case, the dimension of the shielding plate body 124 along the extension direction needs to be set slightly shorter, and the inclination angle α of the side of the protrusion 120 needs to be set slightly larger. This is also feasible.

[0055] In order to facilitate the directional outflow of condensed liquid droplets and prevent the condensed liquid droplets from flowing out along the edge, in this embodiment, a retaining edge is provided on part of the edge of the protective cover 12 to prevent the condensed liquid droplets from flowing out of the corresponding edge. Figure 4 and Figure 5As shown, the edges of the cover body on both sides of the raised portion 120 are provided with first ribs 125, and the edges of the shielding plate body 124 at both ends along the extending direction of the raised portion 120 are provided with second ribs 126, which is conducive to the condensed liquid droplets dripping on the protective cover 12 to flow out to the outside of the module output pole 200 in a directional manner. Moreover, in a specific implementation, the height of the first rib 125 and the second rib 126, that is, the extension size of the first rib 125 and the second rib 126 in the height direction of the protective cover 12, is preferably 2-4mm bracket 11, and is specifically set to 2mm, 3mm or 4mm, etc., to effectively prevent the condensed liquid droplets from flowing out along the corresponding edges.

[0056] In this embodiment, see Figures 1 to 3 As shown, a wire harness accommodating groove 100 is provided on the bracket 11, and the wire harness accommodating groove 100 is arranged opposite to the protrusion 120. The arrangement of the wire harness accommodating groove 100 is conducive to the arrangement of the wire harness 1, and the arrangement of the wire harness accommodating groove 100 and the protrusion 120 opposite to each other can make the wire harness accommodating groove 100 have more space, which is further conducive to the arrangement of the wire harness 1. In addition, the above-mentioned wire harness mounting portion 112 includes a clamping hole provided on the bottom of the wire harness accommodating groove 100. When installing the wire harness 1, the buckle with a cable tie can be clamped in the clamping hole, and the wire harness 1 can be tightened by the cable tie, so as to fix the wire harness 1 on the bracket 11.

[0057] On the basis of the wire harness accommodating groove 100, the bracket 11 of this embodiment is also provided with a copper bar mounting portion 111 for the copper bar 2 to be clamped, and the copper bar mounting portion 111 is two groups symmetrically arranged about the wire harness accommodating groove 100. This is conducive to the fixed installation of the copper bar 2 on the bracket 11, and the bracket 11 can simultaneously install the wire harness 1 and the copper bar 2, and has the characteristics of high integration.

[0058] Specifically, each group of copper busbar installation parts 111 includes a plurality of slots 1011 arranged at intervals along the length direction of the wiring harness accommodating groove 100. The slots 1011 are specifically defined by two relatively arranged clamping brackets 11, and the free ends of the slots 1011 are provided with guide surfaces to facilitate the installation of the copper busbar 2. During the specific installation, it is only necessary to place the copper busbar 2 on the top of the slots 1011 and press it gently, so that the copper busbar 2 is clamped in the slots 1011 through the local deformation of the clamping bracket 11, and then the clamping bracket 11 restores the deformation, and the copper busbar 2 is limited by the barb at the end of the clamping bracket 11 to prevent the copper busbar 2 from falling out of the slots 1011.

[0059] See also Figure 2 and Figure 3As shown, in this embodiment, the bracket 11 is further provided with a connection portion for being connected to the external carrier by snapping. Specifically, the external carrier is provided with a long slot 1011, and the connection portion includes a snap arm 113 extending to a side away from the protective cover 12, and a snap protrusion 1131 provided at the free end of the snap arm 113. When the bracket 11 is installed on the external carrier, the snap protrusion 1131 is snapped in the slot 1011, so that the bracket 11 is better fixed on the external carrier through the cooperation between the snap protrusion 1131 and the slot 1011.

[0060] It should be noted that the external carrier may be, for example, the lower shell of the battery pack, the module end plate 101 or the crossbeam in the battery pack shell, etc. It should also be noted that the bracket 11 of this embodiment is preferably integrally injection molded, and its material may be nylon-66, nylon 6 or PET engineering plastics, etc.

[0061] In addition, in this embodiment, see Figure 2 , Figure 3 , and combined with Figures 6 to 8 As shown, the clamping arms 113 are arranged in two groups symmetrically about the protrusions 120, and two are arranged at intervals in each group. The clamping slots 1011 provided on the external carrier are arranged in a long strip shape, which is conducive to the clamping connection of the clamping protrusions 1131 with different spacings in each group. Due to the shape of the clamping slots 1011, in order to prevent the bracket 11 from moving along the long axis direction of the clamping slots 1011, in this embodiment, a limiting structure is also provided between the bracket 11 and the external carrier.

[0062] Specifically, the limiting structure includes a limiting arm 114 disposed on the bracket 11, and a limiting end face 1141 is disposed on the limiting arm 114. Corresponding to the limiting arm 114, a limiting groove 1012 is disposed on the external carrier, and the limiting end face 1141 abuts against the limiting groove 1012. Through the cooperation between the limiting end face 1141 and the limiting groove 1012, the bracket 11 can be effectively prevented from moving along the long axis direction of the long groove.

[0063] Preferably, the limiting arms 114 are also arranged in two groups symmetrically about the protrusion 120, and two are arranged at intervals in each group. In addition, the limiting groove 1012 on the external carrier is connected to the clamping groove 1011, which is conducive to the processing and preparation of the limiting groove 1012 and the clamping.

[0064] The mounting bracket assembly of this embodiment can guide the condensed liquid droplets to flow to the outside of the module output pole 200, and can effectively protect the module output pole 200, and also help to prevent the condensed liquid droplets from entering the plug-in to prevent corrosion. At the same time, it is also helpful to improve the overall rigidity of the protective cover 12, and can also absorb installation and manufacturing tolerances, and has a good use effect.

[0065] Embodiment 2

[0066] This embodiment relates to a battery pack, in which the mounting bracket assembly of the first embodiment is provided.

[0067] like Figures 6 to 8 As shown, the battery pack of this embodiment has a plurality of battery modules 10, each of which is provided with an intermediate end plate along the direction of stacking of the single cells. The mounting bracket assembly is located between brackets 11 of two adjacent battery modules 10, and the brackets 11 are snap-connected to the opposite intermediate end plates of the two modules.

[0068] Specifically, the middle end plate is provided with a long strip of snap-in grooves and a limit groove 1012, and the two sets of snap-in protrusions 1131 on the bracket 11 are respectively snap-into the snap-in grooves, and the two sets of limit end faces 1141 are respectively abutted against the corresponding limit grooves 1012, so that the bracket 11 is better fixed on the two middle end plates. The wire harness 1 and the copper busbar 2 are respectively installed on the wire harness mounting portion 112 and the copper busbar mounting portion 111, and the end of the wire harness 1 is connected to the module output pole 200. The protective cover 12 is bonded to the bracket 11. The assembly of the mounting bracket assembly is completed in this way.

[0069] The battery pack of this embodiment can guide condensation droplets to flow to the outside of the module output pole 200 by adopting the mounting bracket assembly of the first embodiment, thereby effectively protecting the module output pole 200 and helping to increase the service life of the battery pack.

[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
