[0048] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application.

[0049] The vehicle distribution box is used to distribute the electricity in the vehicle power battery pack, and the shell 100 of the distribution box is made by sheet metal processing of thin plates.

[0050] However, the shell 100 of the current distribution box is relatively thin and weak in strength. When the vehicle is in harsh working conditions for a long time, the shell 100 of the distribution box is easily deformed or even fails, and the service life is relatively short.

[0051] In order to solve the technical problem that the housing 100 of the above-mentioned distribution box is easily deformed or even fails, and has a short service life, the present application provides a distribution box and a vehicle, please refer to Figure 1The distribution box includes a housing 100, a cover plate, a mounting plate 300 and a connector 400. The housing 100 has a first direction X. The housing 100 includes a bottom wall 120 and a side wall 130. The side wall 130 is connected to the bottom wall 120 along the first direction X. The mounting plate 300 is connected to the side wall 130. At least part of the mounting plate 300 is spaced from the bottom wall 120 along the first direction X to form a first space 111. The side of the mounting plate 300 away from the bottom wall 120 is used to install the electrical components. The cover plate is disposed along the first direction X. The cover plate, the side wall 130 and the mounting plate 300 are connected to the side of the side wall 130 away from the bottom wall 120 in the X direction, and the accommodating cavity 110 is enclosed by the cover plate, the side wall 130 and the mounting plate 300; the connecting member 400 is arranged in the first space 111, and the connecting member 400 includes a first protrusion 420, and the first protrusion 420 is respectively connected to the bottom wall 120 and the mounting plate 300; the first protrusion 420 has a first accommodating groove 421, and the first accommodating groove 421 forms a first opening on the first protrusion 420, and the first opening faces the mounting plate 300.

[0052] In some embodiments, the bottom wall 120 and the connector 400 are connected by welding, and the mounting plate 300 and the connector 400 are connected by welding.

[0053] It can be understood that, in the above embodiment, the first protrusion 420 in the connecting member 400 is connected to both the mounting plate 300 and the bottom wall 120 in the first direction X. The first protrusion 420 can guide the force exerted on the mounting plate 300 to the bottom wall 120, and can also guide the force exerted on the bottom wall 120 to the mounting plate 300, thereby improving the mechanical properties of the bottom wall 120 and the mounting plate 300 to avoid warping of the bottom wall 120 and the mounting plate 300.

[0054] In order to reduce the difficulty of installing the distribution box, in some embodiments of the present application, the mounting plate 300 can be first connected to the connector 400 to form a component, and then the component is placed in the accommodating cavity 110, and the connector 400 and the bottom wall 120 are connected to complete the installation of the connector 400 and the mounting plate 300.

[0055] It is understandable that connecting the connector 400 and the bottom wall 120 located in the first space 111 requires opening a hole in the mounting plate 300 to extend the tool into the first space 111, which results in a small operating space and a high degree of operating difficulty. In some optional embodiments, the connector 400 extends along the third direction Z, with the first opening facing the bottom wall 120. After the mounting plate 300 and the connector 400 are placed in the accommodating cavity 110, at least the portion of the connector 400 located on both sides of the accommodating groove needs to be connected to the bottom wall 120 to ensure the connection stability between the protrusion and the bottom wall 120. Therefore, along the second direction Y, two process holes need to be opened on the mounting plate 300 to connect the portion of the connector 400 located on both sides of the accommodating cavity 110 to the bottom wall 120.

[0056] In some embodiments of the present application, the first opening faces the mounting plate 300, that is, the parts of the connector 400 located on both sides of the receiving groove need to be connected to the mounting plate 300, and when the connector 400 and the mounting plate 300 are connected, the operation space is large and the operation difficulty is low. In addition, since only the part of the connector 400 at the bottom of the receiving groove needs to be connected to the bottom wall 120, only one process hole needs to be opened on the mounting plate 300 along the second direction Y to connect the part of the connector 400 located at the bottom of the receiving groove with the bottom wall 120. The number of process holes required is small, and the mechanical properties of the mounting plate 300 are better.

[0057] In some embodiments, see Figure 4 The connecting member 400 also includes a first connecting plate 410 connected to the first protrusion 420, the first connecting plate 410 is connected to the mounting plate 300, the number of the first connecting plates 410 is multiple, the multiple first connecting plates 410 are arranged at intervals, the first protrusion 420 is arranged between at least two adjacent first connecting plates 410, and respectively connects at least two adjacent first connecting plates 410.

[0058] In some embodiments, two first connecting plates 410 are spaced apart along the second direction Y, and the first protrusions 420 are disposed between at least two adjacent first connecting plates 410 along the second direction Y and respectively connect the two adjacent first connecting plates 410 .

[0059] In the above embodiment, a plurality of first connecting plates 410 are provided to increase the connection area between the connecting member 400 and the mounting plate 300, thereby improving the connection stability between the connecting member 400 and the mounting plate 300. In addition, since the connecting member 400 is located between the mounting plate 300 and the bottom wall 120, the connecting member 400 having a more stable connection with the mounting plate 300 can also further improve the mechanical properties of the bottom wall 120.

[0060] In some embodiments, please refer again to Figure 4 The first protrusion 420 includes a first bending portion 422, a second bending portion 423 and a first connecting portion 424. The first bending portion 422 is located between the bottom wall 120 and the mounting plate 300 along the first direction X, and is respectively connected to the bottom wall 120 and the mounting plate 300; the second bending portion 423 and the first bending portion 422 are spaced apart along the second direction Y, the second bending portion 423 is located between the bottom wall 120 and the mounting plate 300 along the first direction X, and is respectively connected to the bottom wall 120 and the mounting plate 300; the first connecting portion 424 is connected to the bottom wall 120, and the first connecting portion 424 is located between the first bending portion 422 and the second bending portion 423 along the second direction Y, and is respectively connected to the first bending portion 422 and the second bending portion 423; the first bending portion 422, the second bending portion 423 and the first connecting portion 424 are surrounded by a first accommodating groove 421; the first direction X and the second direction Y intersect.

[0061] In some embodiments, the connecting member 400 is a bent member, and the first connecting plate 410, the first bending portion 422, the second bending portion 423 and the first connecting portion 424 are all bent from different parts of the same thin plate. In some embodiments, the first connecting plate 410 is welded to the bottom wall 120.

[0062] In some embodiments, the first connecting plate 410 , the first bending portion 422 , the second bending portion 423 , and the first connecting portion 424 have the same thickness.

[0063] In order to further enhance the support of the connecting member 400 on the bottom wall 120 and reduce the possibility of warping of the bottom wall 120, in some embodiments, the thickness of the first connecting portion 424 is greater than the thickness of the first bending portion 422 and the second bending portion 423. Specifically, in some embodiments, the first connecting portion 424 is formed by connecting a plurality of thin plate members stacked and connected along the first direction X, and one of the plurality of thin plate members is located between the first bending portion 422 and the second bending portion 423 along the second direction Y, and connects the first bending portion 422 and the second bending portion 423 respectively.

[0064] In order to further enhance the support of the connection member 400 on the mounting plate 300 and reduce the possibility of warping of the mounting plate 300, in some embodiments, the thickness of the first bending portion 422 and the second bending portion 423 are equal and greater than the thickness of the first connecting portion 424. Specifically, in some embodiments, the first bending portion 422 and the second bending portion 423 are both formed by connecting a plurality of thin plate members arranged along the second direction Y, and one of the plurality of thin plate members is respectively connected to the first connecting plate 410 and the first connecting portion 424.

[0065] In some embodiments, see Figure 2 , Figure 5 and Figure 6 The mounting plate 300 is penetrated by a welding hole 310 along the first direction X, and the welding hole 310 is connected to the first space 111 and the accommodating cavity 110 .

[0066] In some embodiments, the welding device welds the connector 400 and the bottom wall 120 through the welding hole 310 so that at least one of the connection between the first bend portion 422 and the bottom wall 120 along the second direction Y away from the first connection portion 424 and the connection between the second bend portion 423 and the bottom wall 120 along the second direction Y away from the first connection portion 424 is welded together.

[0067] In some embodiments, some of the plurality of welding holes 310 spaced apart along the first direction X are oblong holes. Specifically, the maximum size of the welding hole 310 along the second direction Y is smaller than the maximum size of the welding hole 310 along the third direction Z, so that the welding device can perform more welding in the third direction Z through one welding hole 310. In other words, see Figure 6 , the welding device can form more welding points 140 on the connecting member 400 along the third direction Z in one welding hole 310 .

[0068] In the above embodiment, the welding hole 310 is provided in the mounting plate 300 so that the welding device can pass through the mounting plate 300 from the side of the mounting plate 300 away from the bottom wall 120 through the welding hole 310 to weld and connect the connector 400 and the bottom wall 120 located on the side of the mounting plate 300 close to the bottom wall 120. In some embodiments, the welding hole 310 has a hole wall, and the orthographic projection of the hole wall along the first direction X on the second surface 322 is located within the orthographic projection of the first connecting portion 424 along the first direction X on the second surface 322, so that the welding hole 310 is connected to the accommodating groove 421.

[0069] In the above embodiment, by opening a welding hole 310 connected to the receiving groove 421 on the mounting plate 300, the welding device can weld and connect the first connecting portion 424 and the bottom wall 120, so as to reduce the number of weldings between the connecting member 400 and the bottom wall 120 along the second direction Y, and reduce the manufacturing difficulty of the distribution box, under the premise that the connecting member 400 and the bottom wall 120 have good connection stability. In addition, since the number of weldings between the connecting member 400 and the bottom wall 120 along the second direction Y is reduced, the number of welding holes 310 along the second direction Y can also be reduced, or the size of the welding holes 310 along the second direction Y can be reduced, so that the mechanical properties of the mounting plate 300 are better.

[0070] In some embodiments, see Figure 3 , Figure 4 and Fig. 9 The distribution box also has a second direction Y. The distribution box includes a plurality of connectors 400. The plurality of connectors 400 are arranged at intervals along the second direction Y. The first direction X and the second direction Y intersect.

[0071] In the above embodiment, multiple spaced connectors 400, the mounting plate 300 and the bottom wall 120 form multiple frame structures, which can further improve the mechanical properties of the mounting plate 300 and the bottom wall 120. In some embodiments, the second direction Y is the length direction of the box. The connectors 400 spaced apart along the length direction are shorter, the connectors 400 have greater rigidity and better mechanical properties. The better the support of the connectors 400 to the mounting plate 300 and the bottom wall 120, the better the mechanical properties of the distribution box housing 100.

[0072] In some embodiments, see Figure 1 and Figure 2 The mounting plate 300 is spaced apart from the side wall 130 along a direction perpendicular to the first direction X to form a gap 112; the distribution box also includes a support block 500, which is disposed in the gap 112 and respectively connects the bottom wall 120, the side wall 130 and the mounting plate 300.

[0073] It is understandable that, in order to further improve the mechanical properties of the mounting plate 300, in some embodiments, it is necessary to connect the mounting plate 300 with the bottom wall 120 so that the mounting plate 300 and the bottom wall 120 can share the forces received by each other. In the above embodiment, the gap 112 provides sufficient operating space to connect the mounting plate 300 with the bottom wall 120. In addition, the support block 500 disposed in the gap 112 can not only enable the bottom wall 120 and the mounting plate 300 to share the forces received by each other, but the support block 500 connected to the side wall 130 can also enable the mounting plate 300 and the bottom wall 120 to share the forces received by the side wall 130, thereby improving the mechanical properties of the side wall 130.

[0074] In some embodiments, see Figure 5 and Figure 7 The mounting plate 300 includes a main body portion 320 and a supporting portion 330. The main body portion 320 is spaced apart from the bottom wall 120 along the first direction X and forms a first space 111. The main body portion 320 has a first surface 321 and a second surface 322 that are opposite to each other along the first direction X. The second surface 322 is connected to the connecting member 400. The supporting portion 330 is connected between the second surface 322 and the bottom wall 120 along the first direction X, and is respectively connected to the second surface 322 and the bottom wall 120. The supporting portion 330 is spaced apart from the side wall 130 to form a gap 112. The supporting portion 330 is connected to the supporting block 500.

[0075] In the above embodiment, the support portion 330 is provided so that the mounting plate 300 can extend in the first direction X, thereby being connected to the bottom wall 120, and the support portion 330 enables the mounting plate 300 and the bottom wall 120 to form a relatively stable frame structure, so that the mechanical properties of the housing 100 are further improved. It can be understood that the support portion 330 is larger than the main body 320 in the first direction X. The provision of the support portion 330 can increase the connection area between the mounting plate 300 and the support block 500, thereby improving the supporting effect of the mounting plate 300 on the side wall 130, and further improving the mechanical properties of the housing 100.

[0076] In some embodiments, the main body 320 and the support portion 330 are integrally formed. Specifically, in some embodiments, the main body 320 and the support portion 330 are formed by bending different parts of the same thin plate.

[0077] In some embodiments, see Figure 2 , Figure 5 and Figure 6 The distribution box also includes a second connecting portion 600, which is arranged in the gap 112. The second connecting portion 600 is located between the support portion 330 and the bottom wall 120 along the first direction X, and respectively connects the support portion 330 and the bottom wall 120; at least a portion of the second connecting portion 600 is arranged between the support block 500 and the bottom wall 120 along the first direction X, and connects the support block 500.

[0078] In some embodiments, the mounting plate 300, the support portion 330 and the second connection portion 600 are integrally formed. Specifically, in some embodiments, the mounting plate 300, the support portion 330 and the second connection portion 600 are formed by bending different parts of the same thin plate. In some embodiments, the second connection portion 600 is welded to the bottom wall 120.

[0079] In the above embodiment, the second connection portion 600 can be provided to further increase the connection area between the mounting plate 300 and the bottom wall 120 , thereby improving the connection stability between the bottom wall 120 and the mounting plate 300 , thereby further improving the mechanical properties of the housing 100 .

[0082] In the above embodiment, the fastener 700 having the second connection hole 710 is provided so that the electrical component can be connected to the mounting plate 300 .

[0083] In some embodiments, see Figure 1 and Fig.11The side wall 130 has a first mounting hole 131 connected to the accommodating cavity 110; the distribution box also includes a first reinforcement member 800, the first reinforcement member 800 is arranged in the accommodating cavity 110, the first reinforcement member 800 is connected to the side wall 130, the first reinforcement member 800 has a second mounting hole 810, the first mounting hole 131, the second mounting hole 810, and the accommodating cavity 110 are connected to each other.

[0084] It is understandable that the side wall 130 needs to be provided with a first mounting hole 131 so that the electrical components in the accommodating cavity 110 can be connected to the outside. After the first mounting hole 131 is provided, the strength of the side wall 130 is reduced. In the above embodiment, the first reinforcing member 800 is provided on the side wall 130 to compensate for the reduced strength due to the opening of the side wall 130, thereby improving the mechanical properties of the side wall 130, and further improving the mechanical properties of the housing 100. In some embodiments, the first reinforcing member 800 is welded to the side wall 130.

[0085] In some embodiments, the orthographic projection of the hole wall of the first mounting hole 131 on the outer peripheral surface of the side wall 130 is located within the orthographic projection of the hole wall of the second mounting hole 810 on the outer peripheral surface of the side wall 130 to avoid interference between the electrical components passing through the first mounting hole 131 and the first reinforcement 800.

[0086] In some embodiments, the first reinforcing member 800 is connected to the side wall 130 by welding.

[0087] In the above embodiment, the first reinforcing member 800 is connected to the side wall 130 to increase the mechanical properties of the side wall 130, thereby improving the mechanical properties of the housing 100. In addition, the second mounting hole 810 can also allow the electrical component to pass through the side wall 130 and connect to the outside.

[0088] In some embodiments, please refer again to Fig.11 The side wall 130 includes a first side surface 132 and a second side surface 133, the first mounting hole 131 passes through the first side surface 132, the first side surface 132 and the second side surface 133 are connected, and the first side surface 132 and the second side surface 133 are respectively connected to the bottom wall 120; the first reinforcement piece 800 includes a first reinforcement portion 820 and a flange portion 830, the first reinforcement portion 820 is connected to the first side surface 132, and the second mounting hole 810 passes through the first reinforcement portion 820; the flange portion 830 is connected to the first reinforcement portion 820, and the flange portion 830 is connected to at least one of the second side surface 133 and the bottom wall 120.

[0089] In some embodiments, the first reinforcement portion 820 is connected to the side wall 130 by welding, and the flange portion 830 is connected to the side wall 130 by welding.

[0090] In some embodiments, the flange portion 830 has a maximum size W along the second direction Y, satisfying: W ≥ 15 mm. Specifically, the value of W can be: any one of 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, 25 mm, 26 mm, 27 mm, 28 mm, 29 mm, 30 mm, 31 mm, 32 mm, 33 mm, 34 mm, 35 mm, 36 mm, 37 mm, 38 mm, 39 mm, 40 mm, 41 mm, 42 mm, 43 mm, 44 mm, and 45 mm. This allows the flange portion 830 to have a size along the second direction Y that is larger than the size of the welding head, so that it can be welded to the side wall 130 or the bottom wall 120 for connection.

[0091] In the above embodiment, the flange portion 830 is provided to increase the connection area between the first reinforcement piece 800 and the side wall 130, thereby making the connection between the first reinforcement piece 800 and the side wall 130 more stable, further improving the mechanical properties of the side wall 130 by the first reinforcement piece 800, and further improving the mechanical properties of the box.

[0092] In some embodiments, see Figure 1 and Fig.10 The side wall 130 has a third side surface 134, and the third side surface 134 is connected to the bottom wall 120; the distribution box also includes a second reinforcement piece 900, and the second reinforcement piece 900 is arranged in the accommodating cavity 110. The second reinforcement piece 900 includes a second connecting plate 910 and a bending piece 960, and the second connecting plate 910 is connected to the third side surface 134; the bending piece 960, the bending piece 960 is connected to the second connecting plate 910, and the bending piece 960 is penetrated by a threading groove 113 connected to the accommodating cavity 110, and the threading groove 113 forms a second opening 970 in the bending piece 960, and the second opening 970 faces the third side surface 134, the bending piece 960 is connected to the third side surface 134, and the bending piece 960 is penetrated by a third connecting hole 950, and the third connecting hole 950 is connected to the threading groove 113 and the accommodating cavity 110.

[0093] In some embodiments, the wire groove 113 extends along the first direction X and passes through the bending member 960 to communicate with the accommodating cavity. The wire groove 113 passing through the bending member 960 and communicating with the accommodating cavity 110 can guide the wire harness in the accommodating cavity 110 into the wire groove 113 .

[0094] In some embodiments, the bending member 960 includes a third bending portion 920, a fourth bending portion 930, and a third connecting portion 940. The third bending portion 920 is connected to the third side surface 134, and the third bending portion 920 is connected to the second connecting plate 910; the fourth bending portion 930 is connected to the third side surface 134, and the fourth bending portion 930 is arranged on the side of the third bending portion 920 away from the second connecting plate 910, and the third bending portion 920 and the fourth bending portion 930 are arranged at intervals; the third connecting portion 940 is arranged between the third bending portion 920 and the fourth bending portion 930, and respectively connects the third bending portion 920 and the fourth bending portion 930, and the third connecting portion 940 is arranged at intervals with the third side surface 134 to form a threading groove 113, and the third connecting portion 940 has a third connecting hole 950 connected to the threading groove 113.

[0095] In some embodiments, the second connecting plate 910 is connected to the side wall 130 by welding.

[0096] In some embodiments, the second reinforcement member 900 has multiple second connecting plates 910, at least one of the two second connecting plates 910 is connected to the third bending portion 920 at a side away from the fourth bending portion 930, and the other is connected to the fourth bending portion 930 at a side away from the third bending portion 920.

[0097] In some embodiments, the second connecting plate 910, the third bending portion 920, the fourth bending portion 930 and the third connecting portion 940 are integrally formed. In some embodiments, the second connecting plate 910, the third bending portion 920, the fourth bending portion 930 and the third connecting portion 940 are formed by bending different parts of the same thin plate.

[0098] In some embodiments, the distribution box further includes a buckle for restraining the wiring harness, the buckle is passed through the third connection hole 950 , and a portion of the buckle can be disposed in the wire threading groove 113 .

[0099] In the above embodiment, the buckle can be connected to the box by providing the third connecting portion 940 having the third connecting hole 950. In addition, the third connecting portion 940 can be kept at a certain distance from the side wall 130 by providing the third bending portion 920 and the fourth bending portion 930, thereby forming the threading groove 113 to place the buckle.

[0100] In some embodiments, please refer again to Fig.10 The side wall 130 is penetrated by a third mounting hole 135 communicating with the accommodating cavity 110 , the second connecting plate 910 is penetrated by a fourth mounting hole 911 , and the third mounting hole 135 , the fourth mounting hole 911 , and the accommodating cavity 110 are in communication.

[0101] In some embodiments, the orthographic projection of the hole wall of the third mounting hole 135 on the side wall 130 is located within the orthographic projection of the hole wall of the fourth mounting hole 911 on the side wall 130 to avoid interference between the electrical component passing through the third mounting hole 135 and the second reinforcement member 900 .

[0102] It is understandable that the end of the wire harness needs to be restrained by a buckle and needs to pass through the housing 100 to connect to the outside world. That is, there is an area on the side wall 130 where the third mounting hole 135 needs to be opened, and the mechanical properties of this area are insufficient.

[0103] In the above embodiment, the second reinforcement piece 900 can not only improve the mechanical properties of the side wall 130 area where the third mounting hole 135 is opened, but also connect the buckle, which not only improves the mechanical properties of the housing 100 but also facilitates the installation of the electrical components.

[0104] Accordingly, the present application also provides a vehicle, comprising a distribution box as in any one of the above embodiments. The vehicle having the distribution box has higher reliability due to the good mechanical properties of the distribution box housing.
