[0044] The embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0045] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0046] In the description of the present utility model, the "first feature" and "second feature" may include one or more of such features.

[0047] In the description of the present utility model, "a plurality of" means two or more, and "several" means one or more.

[0048] Next, the distribution box 1 according to an embodiment of the present utility model will be described with reference to the drawings.

[0049] As Figures 1-5 shown, the distribution box 1 according to an embodiment of the present utility model includes a housing 100, a sealing cover 200, and a plurality of electrical distribution components 300.

[0050] The sealing cover 200 is connected to the housing 100 and seals the housing 100, and a plurality of electrical distribution components 300 are connected to the sealing cover 200 and at least partially accommodated in the housing 100.

[0051] Among them, the fact that a plurality of electrical distribution components 300 are connected to the sealing cover 200 and at least partially accommodated in the housing 100 means that a plurality of electrical distribution components 300 can be fixed to the sealing cover 200. At the same time, a part of the plurality of electrical distribution components 300 can be accommodated in the sealing cover 100 and another part can be accommodated in the housing 100, or all of the plurality of electrical distribution components 300 can also be accommodated in the housing 100.

[0052] For example, a power distribution cavity 110 can be constructed in the housing 100, the sealing cover 200 seals the power distribution cavity 110, and at least part of the plurality of electrical distribution components 300 are accommodated in the power distribution cavity 110.

[0053] The distribution box 1 implemented according to the present utility model directly connects a plurality of distribution components 300 to the sealing cover 200, which can improve the integration degree of the sealing cover 200. Compared with the distribution box 1 in the traditional technology, in this embodiment, the plastic box body for fixing the distribution components 300 can be omitted, which not only reduces the number of components inside the distribution box 1, makes the internal structure of the distribution box 1 simpler, but also directly fixes the plurality of distribution components 300 on the sealing cover 200, and the assembly and fixing structure of the distribution components 300 is simpler, and the assembly is more convenient and fast.

[0054] In addition, after omitting the plastic box body, the heat-conducting medium 500 (such as heat-conducting glue) inside the distribution box 1 can directly fill the space between the distribution components 300 and the housing 100, thereby avoiding the problem of redundant space between the plastic box body and the housing 100, that is, avoiding the influence on the heat dissipation effect due to the redundant space between the plurality of distribution components 300 and the housing 100. The plurality of distribution components 300 can directly transfer heat to the housing 100 through the heat-conducting medium 500 and release it outward, and thus can greatly improve the heat dissipation efficiency of the distribution box 1, and the heat dissipation effect of the distribution components 300 is better.

[0055] Thus, the distribution box 1 according to the embodiment of the present utility model has the advantages of high integration degree, simple structure and better heat dissipation effect.

[0056] In some specific embodiments of the present utility model, as Figure 4 shown, the plurality of distribution components 300 include a pre-charge component 310, a main fuse 320 and a relay 330. The pre-charge component 310, the main fuse 320 and the relay 330 are arranged along the length direction of the sealing cover 200 and are respectively connected to the sealing cover 200.

[0057] By providing the pre-charge component 310, the pre-charge component 331 can avoid the capacitive impact on the battery cells of the battery pack when the motor electronic control is powered on, so as to protect the battery cells.

[0058] It can be understood that the dimension of the sealing cover 200 in the length direction is relatively large. By arranging the pre-charge component 310, the main fuse 320 and the relay 330 along the length direction of the sealing cover 200, the position interference between the pre-charge component 310, the main fuse 320 and the relay 330 can be avoided, which is convenient for layout, and thus it is convenient to integrally fix the pre-charge component 310, the main fuse 320 and the relay 330 on the sealing cover 200.

[0059] Moreover, by connecting the pre-charging component 310, the main fuse 320, and the relay 330 to the sealing cover 200 respectively, the connection structures between the pre-charging component 310, the main fuse 320, and the relay 330 and the sealing cover 200 can be independent of each other, further improving the connection stability between the pre-charging component 310, the main fuse 320, and the relay 330 and the sealing cover 200.

[0060] Further, as Figure 4 shown, in the width direction of the sealing cover 200, the main fuse 320 is at least partially staggered with the pre-charging component 310 and the relay 330 respectively.

[0061] It should be noted that, after assembly, the width direction of the sealing cover 200 is the up-and-down direction. By staggering the main fuse 320 with other distribution components 300, the heat-conducting medium 500 can only be filled between the pre-charging component 310, the relay 330, and the housing 100, thus avoiding interference between the heat-conducting medium 500 and the main fuse 320.

[0062] Moreover, by staggering the main fuse 320 with the pre-charging component 310 and the relay 330 at least partially, in the length direction of the sealing cover 200, a part of the main fuse 320 can overlap with a part of the pre-charging component 310 or a part of the relay 330, which neither causes position interference between the main fuse 320 and the pre-charging component 310 or the relay 330, nor increases the occupied space of the main fuse 320, the pre-charging component 310, and the relay 330 in the length direction of the sealing cover 200, making the layout and installation more convenient.

[0063] In some specific embodiments of the present invention, as Figure 2 shown, the distribution box 1 further includes a heat-conducting medium 500, and the heat-conducting medium 500 is filled in the housing 100 and at least covers a part of the pre-charging component 310 and a part of the relay 330.

[0064] For example, the heat-conducting medium 500 can be heat-conducting glue.

[0065] In this way, the heat generated by the pre-charging component 310 can be directly transferred to the housing 100 through the heat-conducting medium 500, and the heat generated by the relay 330 can be directly transferred to the housing 100 through the heat-conducting medium 500, further improving the heat dissipation efficiency of the pre-charging component 310 and the relay 330, and achieving better heat dissipation effect.

[0066] In some specific embodiments of the present invention, as Figure 4 shown, the relay 330 is provided with a coil 331, the heat-conducting medium 500 at least covers the coil 331, and the main fuse 320 and the heat-conducting medium 500 are spaced apart.

[0067] It is understandable that the heat in the relay 330 is mainly generated in the coil 331. By covering the coil 331 with the heat-conducting medium 500, the heat generated by the coil 331 can be directly transferred to the housing 100 through the heat-conducting medium 500. The heat-conducting efficiency of the coil 331 to the housing 100 is faster, and thus the heat generated by the coil 331 can be quickly transferred outwards to ensure better heat dissipation effect of the coil 331.

[0068] In addition, by arranging the main fuse 320 and the heat-conducting medium 500 at intervals, the heat-conducting medium 500 will not adhere to the main fuse 320, which is convenient for replacing the main fuse 320 during later maintenance of the main fuse 320, and the maintenance operation is more convenient.

[0069] In some specific embodiments of the present invention, a glue injection hole 130 is formed on one side in the width direction of the housing 100, and the glue injection hole 130 and a plurality of electrical distribution components 300 are arranged alternately.

[0070] Wherein, the inner diameter of the glue injection hole 130 can be 10 mm.

[0071] For example, the glue injection hole 130 can be arranged on the upper side surface of the housing 100, which is convenient for injecting the heat-conducting medium 500 into the housing 100 (i.e., into the electrical distribution cavity 110) through the glue injection hole 130, and after the glue injection is completed, the heat-conducting medium 500 is not easy to flow out from the glue injection hole 130, which is convenient for sealing the glue injection hole 130.

[0072] In addition, the glue injection hole 130 can be sealed by a rubber plug 131. The rubber plug 131 can be made of metal, and the rubber plug 131 can be fixedly bonded in the glue injection hole 130 with glue to seal the glue injection hole 130.

[0073] Furthermore, by arranging the glue injection hole 130 and a plurality of electrical distribution components 300 alternately, when injecting the heat-conducting medium 500 into the electrical distribution cavity 110 through the glue injection hole 130, the heat-conducting medium 500 can directly flow to the bottom of the electrical distribution cavity 110 to preferentially fill the lower space of the electrical distribution cavity 110, avoiding the heat-conducting medium 500 falling on the electrical distribution components 300 and being unable to fill the lower space of the electrical distribution cavity 110.

[0074] In some specific embodiments of the present invention, an insulating layer is provided on the inner wall of the electrical distribution cavity 110.

[0075] Among them, the insulating layer can be coated on the inner wall of the power distribution cavity 110 or attached to the inner wall of the power distribution cavity 110 by means of film sticking. The thickness of the insulating layer can be 0.1 mm to 0.3 mm. By providing the insulating layer, the inner wall of the power distribution cavity 110 can be completely disconnected from the power distribution components 300, more effectively avoiding electrical conduction between the power distribution components 300 and the inner wall of the power distribution cavity 110, and the safety of electrical connection is higher.

[0076] In some specific embodiments of the present utility model, the sealing cover 200 is provided with a plurality of threaded posts 210, and the pre-charging component 310 is provided with a plurality of mounting ears 311. The plurality of mounting ears 311 are connected to the plurality of threaded posts 210 one by one through a plurality of first fasteners 312.

[0077] Among them, the threaded posts 210 can extend along the thickness direction of the sealing cover 200, and internal threads are formed in the threaded posts 210. The threaded posts 210 can be fixed to the inner side of the sealing cover 200 by means of welding, die casting, molding, gluing, etc.

[0078] In this way, during assembly, the mounting ears 311 can be fixed to the side of the threaded posts 210 facing away from the sealing cover 200 through the first fasteners 312, and then the pre-charging component 310 can be fixed to the sealing cover 200.

[0079] In some specific embodiments of the present utility model, as Figure 4 shown, the sealing cover 200 is provided with a plurality of first connecting pieces 220, and a plurality of second connecting pieces 321 are provided on opposite sides of the main fuse 320. The first connecting pieces 220 are supported below the second connecting pieces 321, and the plurality of second connecting pieces 321 are connected to the plurality of first connecting pieces 220 one by one through a plurality of second fasteners 322.

[0080] Among them, the first connecting pieces 220 can be fixed to the inner side of the sealing cover 200 by means of welding, die casting, molding, gluing, etc.

[0081] In this way, during assembly, the second connecting pieces 321 can be fixed to the upper side of the first connecting pieces 220 through the second fasteners 322, and then the main fuse 320 can be fixed to the sealing cover 200. Moreover, the first connecting pieces 220 can support and fix the second connecting pieces 321 from below, making the fixation of the main fuse 320 more reliable.

[0082] Furthermore, as Figure 5 shown, along the thickness direction of the sealing cover 200 away from the sealing cover 200, the side of the first connecting piece 220 facing away from the second connecting piece 321 is inclined towards the direction close to the first connecting piece 220.

[0083] With such a setting, the first connecting piece 220 can be configured in a triangular shape, and the thickness of the side of the first connecting piece 220 facing the sealing cover 200 can be relatively thick to ensure that the connection strength between the first connecting piece 220 and the sealing cover 200 can be relatively high. At the same time, the support stability of the first connecting piece 220 can be higher, and thus the main fuse 320 can be more reliably fixed to the sealing cover 200 by using the first connecting piece 220.

[0084] In addition, the side of the first connecting piece 220 facing the second connecting piece 321 can be kept horizontal, that is, the upper side of the first connecting piece 220 can be kept horizontal to facilitate connection and fixation with the first connecting piece 220.

[0085] In some specific embodiments of the present utility model, as Figure 4 and Figure 5 shown, the sealing cover 200 is provided with a plurality of fixing brackets 230, and the fixing brackets 230 include a supporting portion 231 and a stopping portion 232.

[0086] The supporting portion 231 extends along the length direction of the sealing cover 200, and the supporting portions 231 of the plurality of fixing brackets 230 all support on one side of the relay 330 in the width direction of the sealing cover 200. The stopping portion 232 extends along the width direction of the sealing cover 200, and the stopping portions 232 of the plurality of fixing brackets 230 respectively stop on the opposite sides of the relay 330 in the length direction of the sealing cover 200. That is, the fixing bracket 230 can be configured in an "L" shape.

[0087] Among them, the fixing bracket 230 can be fixed to the inner side of the sealing cover 200 by means of welding, die-casting, molding, gluing, etc. Among them, the width direction of the sealing cover 200 is the up-and-down direction.

[0088] Among them, along the length direction of the sealing cover 200, the supporting portion 231 can be 15 mm to 20 mm; and, along the width direction of the sealing cover 200, the stopping portion 232 can be 15 mm to 20 mm; and, along the thickness direction of the sealing cover 200, the sizes of both the supporting portion 231 and the stopping portion 232 can be 15 mm to 20 mm.

[0089] In this way, the supporting portions 231 of the plurality of fixing brackets 230 can support the relay 330 from below the relay 330 to fix the relay 330 in the up-and-down direction, and the stopping portions 232 of the plurality of fixing brackets 230 can limit and fix the relay 330 in the length direction of the sealing cover 200 to realize pre-fixation of the relay 330.

[0090] In addition, after filling the heat-conducting medium 500 in the power distribution cavity 110, the heat-conducting medium 500 can wrap the relay 330 and the pre-charging component 310. Furthermore, the heat-conducting medium 500 can be used to further fix the relay 330 and the pre-charging component 310, so that the fixing of the power distribution device 300 in the power distribution cavity 110 is more stable and reliable.

[0091] In some specific embodiments of the present utility model, as Figure 3 shown, an inspection opening 120 is formed on one side in the width direction of the housing 100, and at least the main fuse 320 is exposed from the inspection opening 120.

[0092] Among them, the inspection opening 120 can be arranged on the upper side surface of the housing 100, and the inspection opening 120 can be arranged at an interval from the glue injection port described above. Moreover, the size of the inspection opening 120 needs to meet the operating space for replacing the main fuse 320.

[0093] By providing the inspection opening 120, when the main fuse 320 fails (for example, the fuse is short-circuited and blown), the main fuse 320 can be directly repaired or replaced through the inspection opening 120, without the need to disassemble the sealing cover 200 and the housing 100, which is beneficial to simplifying the maintenance operation of the main fuse 320.

[0094] In addition, an inspection cover 121 can be provided. The inspection cover 121 can be installed in cooperation with the inspection opening 120 through bolts to cover the inspection opening 120. Moreover, a rubber sealing ring can be arranged on the circumferential direction of the inspection opening 120 to seal the gap between the inspection cover 121 and the housing 100, and the sealing performance of the inspection opening 120 is better.

[0095] In some specific embodiments of the present utility model, as Figure 2 and Figure 3 shown, at least one of the housing 100 and the sealing cover 200 is provided with a sealing groove 140, and a sealing member 141 is arranged in the sealing groove 140 to seal the gap between the housing 100 and the sealing cover 200.

[0096] Among them, the sealing member 141 can be a rubber sealing ring.

[0097] For example, the sealing groove 140 can be arranged on the housing 100, or the sealing groove 140 can be arranged on the sealing cover 200, or the sealing grooves 140 can be arranged on both the housing 100 and the sealing cover 200, and the sealing member 141 is arranged in the sealing groove 140. In addition, there can also be multiple sealing members 141, and the multiple sealing members 141 can form a multiple sealing.

[0098] In this way, the sealing performance between the sealing cover 200 and the housing 100 can be improved, and after the assembly is completed, it can prevent dust, impurities or water from entering the power distribution cavity 110 through the gap between the sealing cover 200 and the housing, so as to ensure the dryness and cleanliness inside the power distribution cavity 110, and further ensure the safety of the electrical connection inside the power distribution cavity 110.

[0099] Furthermore, as Figure 3 shown, the housing 100 is provided with a plurality of threaded holes 150, and the plurality of threaded holes 150 are arranged at intervals along the circumferential direction of the housing 100. The sealing cover 200 is provided with a plurality of through holes 240, and the plurality of through holes 240 are arranged along the circumferential direction of the sealing cover 200, and the plurality of through holes 240 and the plurality of threaded holes 150 are screwed together in one-to-one correspondence through a plurality of third fasteners (not shown in the figure).

[0100] Among them, the threaded holes 150 and the sealing grooves 140 can be arranged at intervals to prevent the connection between the housing 100 and the sealing cover 200 from damaging the sealing structure between the housing 100 and the sealing cover 200.

[0101] By using a plurality of third fasteners to press the sealing cover 200 against the housing 100 through the heat-conducting medium (500), not only can the connection reliability between the sealing cover 200 and the housing 100 be improved, but also the pressing force of the sealing cover 200 and the housing 100 on the seal 141 can be increased, further improving the sealing effect between the sealing cover 200 and the housing 100.

[0102] Next, refer to the accompanying drawings to describe the battery pack tray 2 according to an embodiment of the present invention.
