[0049] The specific implementation methods of the present application are further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application but are not intended to limit the scope of the present application.

[0050] The embodiment of the present application discloses a charging and distribution box 100 of a vehicle 1000 and the vehicle 1000. The charging and distribution box 100 is arranged on the vehicle 1000 and is used to manage the charging and power consumption of the vehicle 1000. The vehicle 1000 further includes a vehicle body 200, and the charging and distribution box 100 is installed on the vehicle body 200.

[0051] like Figure 1-Figure 11 As shown, the charging and distribution box 100 according to the embodiment of the present application includes: a box body 1, a charging and distribution unit group (not shown in the figure), a first connection structure 3 and a second connection structure 4. The box body 1 defines an installation space 11 and the outer wall is provided with at least one distribution socket 2, and the distribution socket 2 is connected to the installation space 11. In other words, the outer wall of the box body 1 is provided with one distribution socket 2, or the outer wall of the box body 1 is provided with multiple distribution sockets 2.

[0052] The installation space 11 is used to accommodate components, the power distribution socket 2 is suitable for connection with the electrical connection plug of the wiring harness, and the charging and distribution unit group is arranged in the box body 1. The charging and distribution unit group includes at least one type of charging and distribution unit, and the charging and distribution unit is electrically connected to the corresponding power distribution socket 2. That is, the charging and distribution unit is electrically connected to the wiring harness through the power distribution socket 2, and then the charging and distribution unit is electrically connected to the electrical device at the other end of the wiring harness. By increasing the types of charging and distribution units in the box body 1, the functions of the charging and distribution box 100 can be increased.

[0053] Furthermore, the first connection structure 3 and the second connection structure 4 are both arranged on the outer side wall of the box body 1 and are spaced apart along the first direction of the charging and distribution box 100. In some embodiments, the first direction of the charging and distribution box 100 may refer to the length direction of the charging and distribution box 100, that is, Figure 2 However, the present application is not limited thereto. In some other embodiments, the first direction of the charging and distribution box 100 may refer to the width direction of the charging and distribution box 100, that is, Figure 2 The left and right direction in .

[0054] At the same time, the vehicle body 200 is provided with a connection gap 240, one of the first connection structure 3 and the second connection structure 4 is suitable for being inserted into and limited in the connection gap 240 of the vehicle body 200, and the other is suitable for being fixedly connected to the vehicle body 200. That is, the first connection structure 3 is suitable for being inserted into and limited in the connection gap 240 of the vehicle body 200, and the second connection structure 4 is fixedly connected to the vehicle body 200, or the second connection structure 4 is suitable for being inserted into and limited in the connection gap 240 of the vehicle body 200, and the first connection structure 3 is fixedly connected to the vehicle body 200. It should be noted that the one of the first connection structure 3 and the second connection structure 4 that is fixedly connected to the vehicle body 200 can be fixedly connected to the vehicle body 200 by means including but not limited to screwing, riveting, and welding.

[0055] When the assembler assembles the charging and distribution box 100 to the vehicle 1000, the assembler first inserts one of the first connection structure 3 and the second connection structure 4 corresponding to the connection gap 240 into the connection gap 240, and limits the connection structure (i.e., the first connection structure 3 or the second connection structure 4) by two opposite surfaces of the connection gap 240, so that the one of the first connection structure 3 and the second connection structure 4 corresponding to the connection gap 240 cannot continue to move, so that the side of the box body 1 close to the connection gap 240 can be fixed to the vehicle body 200. Then the assembler fixes one of the first connection structure 3 and the second connection structure 4 that is not connected to the vehicle body 200 to the vehicle body 200, so that the other side of the box body 1 can be fixed to the vehicle body 200. At this time, both sides of the box body 1 are fixed to the vehicle body 200, and the assembly process of the charging and distribution box 100 on the vehicle body 200 can be completed.

[0056] Therefore, the assembler first inserts one of the first connection structure 3 and the second connection structure 4 that matches the connection gap 240 into the connection gap 240, and then fixes the other one to the vehicle body 200, so as to complete the assembly of the charging and distribution box 100 on the vehicle body 200. Compared with the prior art, one of the first connection structure 3 and the second connection structure 4 is plugged in and matched with the vehicle body 200, which can reduce the number of fasteners required to assemble when fixing the charging and distribution box 100 to the vehicle body 200, improve the installation efficiency of the charging and distribution box 100 on the vehicle body 200, and reduce the assembly time of the vehicle 1000. In addition, no installation tools are required when the charging and distribution box 100 is plugged in and matched with the vehicle body 200, thereby reducing the size of the space on the vehicle body 200 for avoiding installation tools.

[0057] It should be understood that the first direction of the charging and distribution box 100 can be the same as, opposite to, or at an angle to the front-rear direction of the vehicle 1000. In other words, the charging and distribution box 100 can be set in a specific installation direction according to the actual structure of the vehicle body 200, so that the assembler can fix the charging and distribution box 100 to the vehicle body 200.

[0058] like Figure 1-Figure 3 , Figure 5-Figure 7 As shown, in some embodiments of the present application, the outer wall surface of the vehicle body 200 is provided with a clip 210, and the clip 210 includes a clamping portion 211 and a connecting portion 212. The clamping portion 211 is spaced apart from the outer wall surface of the vehicle body 200 to form a connecting gap 240. Figure 2 In the embodiment shown, the clamping portion 211 is spaced apart from the outer wall surface of the vehicle body 200 along the height direction of the charging and distribution box 100. The height direction of the charging and distribution box 100 can be Figure 2 The connecting portion 212 is connected between the end of the clamping portion 211 away from the box body 1 and the vehicle body 200, wherein an opening communicating with the connecting gap 240 is formed between the clamping portion 211 and the outer wall surface of the vehicle body 200, and the opening is open toward the box body 1.

[0059] Furthermore, the first connection structure 3 is adapted to be inserted from the opening between the clamping portion 211 and the outer wall of the vehicle body 200 and limited in the connection gap 240. The first connection structure 3 includes a plug-in portion 31, which is inserted along the first direction (i.e. Figure 1 The plug-in plate portion 31 is configured to extend into the connection gap 240 and be clamped between the clamping portion 211 and the outer wall surface of the vehicle body 200. By clamping the plug-in plate portion 31 with the clamping portion 211 and the outer wall surface of the vehicle body 200, the clamping portion 211 and the outer wall surface of the vehicle body 200 can jointly restrict the plug-in plate portion 31 from moving closer to or away from the vehicle body 200, so that the plug-in plate portion 31 can restrict one side of the charging and distribution box 100 from moving closer to or away from the vehicle body 200 through the first connection structure 3, thereby achieving the technical effect of fixing one side of the charging and distribution box 100 to the vehicle body 200.

[0060] Furthermore, the clip 210 can be elastically deformed, and the clamping portion 211 can rotate around the connection between the clamping portion 211 and the connecting portion 212. When the plug-in plate portion 31 is inserted between the clamping portion 211 and the outer wall surface of the vehicle body 200, the plug-in plate portion 31 can drive the clamping portion 211 to separate from the outer wall surface of the vehicle body 200, and the clamping portion 211 rotates relative to the connecting portion 212. The clip 210 generates elastic deformation and generates elastic force. The elastic force of the clamping portion 211 acts on the plug-in plate portion 31, so that the plug-in plate portion 31 can be reliably clamped between the clamping portion 211 and the outer wall surface of the vehicle body 200, thereby minimizing the loosening of the side of the charging and distribution box 100 having the plug-in plate portion 31 on the vehicle body 200, thereby improving the connection reliability between the charging and distribution box 100 and the vehicle body 200.

[0061] In some embodiments, such as Figure 5-Figure 7As shown, a limit baffle 230 is further provided on the outer wall of the vehicle body 200. The limit baffle 230 is adjacent to the connecting portion 212, and when the plug-in plate portion 31 is inserted between the clamping portion 211 and the outer wall of the vehicle body 200, the limit baffle 230 is located on the outer side of the plug-in plate portion 31. The limit baffle 230 is suitable for abutting against the plug-in plate portion 31. The limit baffle 230 is used to limit the movement of the plug-in plate portion 31 along the radial direction of the charging and distribution box 100, and can prevent the plug-in plate portion 31 from slipping out of the connection gap 240, thereby ensuring that the charging and distribution box 100 is reliably fixed to the vehicle body 200 through the first connecting structure 3.

[0062] Furthermore, if Figure 3-Figure 6 As shown, the plug-in board portion 31 and the box body 1 are arranged along the first direction (i.e. Figure 1 The first connection structure 3 is spaced apart from the first plate portion 31 and the box body 1 in the front-to-back direction. The first connection structure 3 also includes a first connection portion 32. The first connection portion 32 is connected between the plug plate portion 31 and the box body 1, and the first connection portion 32 is detachably connected and matched with the plug plate portion 31. Specifically, one end of the first connection portion 32 is fixedly connected to the outer wall of the box body 1, and the end of the first connection portion 32 close to the plug plate portion 31 is provided with a positioning groove 321 and a fixing groove 322. The plug plate portion 31 is correspondingly provided with a positioning slider and a fixing column. After the plug plate portion 31 is positioned and matched with the positioning groove 321 by using the positioning slider, the first connection portion 32 can be connected and matched with the plug plate portion 31 by extending the fixing column into the fixing groove 322.

[0063] By making the first connection portion 32 and the plug-in plate portion 31 detachably connected and matched, the assembler can design a connection gap 240 of a suitable size on the vehicle body 200 according to the type and model of the vehicle 1000, and then select a matching plug-in plate portion 31 according to the size of the connection gap 240, and connect and match the matching plug-in plate portion 31 with the first connection portion 32. In this way, the first connection structure 3 can be adapted to vehicle bodies 200 of different models, thereby improving the versatility of the charging and distribution box 100 and reducing the design cost and design time of the charging and distribution box 100.

[0064] like Figure 4-Figure 6 As shown, in some embodiments of the present application, along the second direction of the charging and distribution box 100, at least one side wall of the first connection portion 32 may be provided with a reinforcing block 33, and the reinforcing block 33 is fixedly connected to the outer side wall of the box body 1, wherein the first direction of the charging and distribution box 100 is perpendicular to the second direction. When the first direction of the charging and distribution box 100 is Figure 1 When the front-to-back direction is Figure 1 The left and right direction in .

[0065] The reinforcement block 33 is used to improve the structural strength of the first connection portion 32. Specifically, the first connection portion 32 can be configured as a bent plate, which can enable the first connection structure 3 to have good fracture resistance. The reinforcement block 33 and the first connection portion 32 form a triangular stable structure, and the reinforcement block 33 can limit the change in the bending angle of the first connection portion 32, so that the first connection structure 3 is not easily deformed, thereby improving the structural strength of the first connection structure 3.

[0066] In some preferred embodiments, both side walls of the first connection portion 32 are provided with reinforcement blocks 33, which can effectively improve the structural strength of the first connection structure 3. In addition, the reinforcement blocks 33 are fixedly connected to the outer side walls of the box body 1, so that a force transmission path is formed between the reinforcement blocks 33 and the box body 1, and the box body 1 can support the reinforcement blocks 33, so that the reinforcement blocks 33 can improve the structural strength of the first connection structure 3 better.

[0067] like Figure 1 , Figure 4 , Figure 6 As shown, in some embodiments of the present application, the outer side wall of the box body 1 provided with the first connection structure 3 is also provided with a support bar 12, the support bar 12 is extended along the second direction of the charging and distribution box 100 and passes through the reinforcement block 33, and the bottom wall of the reinforcement block 33 opposite to the vehicle body 200 can be provided with an avoidance groove 34, and the avoidance groove 34 is used to avoid the support bar 12. Among them, the support bar 12 is used to improve the structural strength of the box body 1. When the first connection structure 3 rotates around the box body 1 after being impacted, the support bar 12 can try to avoid the torsional deformation of the box body 1. In addition, the support bar 12 can support the reinforcement block 33, which can try to prevent the reinforcement block 33 from rotating and deforming.

[0068] like Figure 6 , Figure 7 As shown, in some embodiments of the present application, a guide portion 213 may be provided at the end of the clamping portion 211 close to the box body 1, and the guide portion 213 is bent in a direction away from the outer wall surface, and the reinforcing block 33 is suitable for abutting with the guide portion 213. Among them, after the plug-in plate portion 31 is inserted into the clamping portion 211 and the outer wall surface of the vehicle body 200, when the reinforcing block 33 abuts with the guide portion 213, the guide portion 213 can limit the reinforcing block 33 from continuing to move close to the installation gap, proving that the plug-in plate portion 31 has been installed in place in the installation gap at this time, and the guide portion 213 can limit the position of the plug-in plate portion 31 in the installation gap, thereby avoiding the insufficient or excessive length of the plug-in plate portion 31 extending into the installation gap, and further improving the consistency of the installation position of the charging and distribution box 100 on the vehicle 1000.

[0069] Furthermore, by bending the guide portion 213 in a direction away from the outer wall surface, the surface of the guide portion 213 opposite to the plug-in plate portion 31 is constructed as a guide slope, which can guide the plug-in plate portion 31, thereby facilitating the insertion of the plug-in plate portion 31 into the installation gap, further reducing the difficulty of installing the first connecting structure 3.

[0070] like Figure 1-Figure 4 , Figure 8 As shown, in some embodiments of the present application, when the first connection structure 3 is suitable for being inserted into and limited in the connection gap 240 of the vehicle body 200, the second connection structure 4 is suitable for being fixedly connected to the vehicle body 200. The outer wall surface of the vehicle body 200 may be provided with a first mounting portion 220, and the second connection structure 4 includes a second mounting portion 41, which is suitable for being arranged opposite to the first mounting portion 220, and the first fastener 51 passes through the first mounting portion 220 and the second mounting portion 41 to fix the first connection structure 3 and the vehicle body 200.

[0071] The first mounting portion 220 and the second mounting portion 41 may both be provided with connection holes, and the first fastener 51 may be a bolt. When the connection hole of the first mounting portion 220 is aligned with the connection hole of the second mounting portion 41, the bolt passes through the first mounting portion 220 and the second mounting portion 41 to fix the second connection structure 4 and the vehicle body 200, and then the second connection structure 4 may fix the box body 1 and the vehicle body 200. Of course, in some embodiments, the first fastener 51 may also be a rivet or the like.

[0072] According to the charging and distribution box 100 of the embodiment of the present application, a conductive layer is provided on the surface of the second mounting part 41 opposite to the vehicle body 200. The conductive layer can be formed by coating a conductive paint on the outer surface of the second mounting part 41. The conductive layer is sandwiched between the second mounting part 41 and the first mounting part 220. The conductive layer is used to form a circuit path between the second mounting part 41 and the first mounting part 220. The box body 1 can be grounded through the first mounting part 220 and the vehicle body 200. The conductive layer can improve the grounding effect of the box body 1. At the same time, such a configuration can make the charging and distribution box 100 do not need to be equipped with a grounding wire, thereby reducing the manufacturing cost of the charging and distribution box 100.

[0073] Furthermore, if Figure 1-Figure 4 As shown, the second mounting portion 41 and the box body 1 are arranged along the first direction (i.e. Figure 1The second connection structure 4 is spaced apart from the second mounting portion 41 and the box body 1 in the front-to-back direction, and the second connection structure 4 also includes a second connection portion 42, which is connected between the second mounting portion 41 and the box body 1, and one end of the second connection portion 42 close to the second mounting portion 41 is inclined toward the vehicle body 200. The second connection portion 42 can be configured as a connection plate, and by obliquely connecting the connection plate between the second mounting portion 41 and the box body 1, it can be ensured that the second mounting portion 41 fits the vehicle body 200, while the spacing distance between the box body 1 and the vehicle body 200 meets the design requirements.

[0074] Furthermore, compared to setting the second connection portion 42 and the second mounting portion 41 flush, setting an angle between the second connection portion 42 and the second mounting portion 41 can improve the structural strength of the second connection structure 4, and can avoid the second connection structure 4 from breaking after being subjected to an impact force along the first direction of the charging and distribution box 100 as much as possible, thereby improving the connection reliability between the charging and distribution box 100 and the vehicle body 200.

[0075] like Figure 2-Figure 4 , Figure 8 As shown, in some embodiments of the present application, along the second direction of the charging and distribution box 100, at least one side wall of the second connection structure 4 may be provided with a reinforcing plate 43, and the reinforcing plate 43 is used to improve the structural strength of the second connection structure 4. Specifically, the reinforcing plate 43 is fixedly connected to the second connection portion 42 and the second mounting portion 41, and there is an angle between the second connection portion 42 and the second mounting portion 41. The reinforcing plate 43, the second connection portion 42 and the second mounting portion 41 form a triangular stable structure, and the reinforcing plate 43 can limit the change in the angle between the second connection portion 42 and the second mounting portion 41, so that the second connection structure 4 is not easily deformed, thereby improving the structural strength of the second connection structure 4.

[0076] In some preferred embodiments, both side walls of the second connection structure 4 are provided with reinforcing plates 43, which can effectively improve the structural strength of the second connection structure 4. In addition, the reinforcing plates 43 are fixedly connected to the outer side walls of the box body 1, so that a force transmission path is formed between the reinforcing plates 43 and the box body 1, and the box body 1 can support the reinforcing plates 43, so that the reinforcing plates 43 can improve the structural strength of the second connection structure 4 better.

[0077] In some embodiments of the present application, the types of the power distribution socket 2 include: an AC charging socket 21, a power supply socket 22 or a battery connection socket 23. Among them, the AC charging socket 21 is used to electrically connect to an external AC charging source, and the external AC charging source can provide 220V AC power to the charging and distribution box 100 through the AC charging socket 21. The power supply socket 22 is connected to a lead-acid battery and / or a CAN (Control Area Network) network, and the lead-acid battery is used to provide 9V to 16V current to the charging and distribution box 100, and the CAN network is used to transmit charging or distribution signals to the charging and distribution box 100. The battery connection socket 23 is used to electrically connect to the power battery pack so that electrical energy is transmitted between the charging and distribution box 100 and the power battery pack. Preferably, the charging and distribution box 100 can be provided with an AC charging socket 21, a power supply socket 22 and a battery connection socket 23 at the same time, so that the functionality of the charging and distribution box 100 can be improved.

[0078] Based on this, the type of the charging and distribution unit can be an on-board charger, a DC / DC (Direct Current / Direct Current-Direct Current to Direct Current) converter, a PDU ((Power Distribution Unit-high voltage distribution unit) controller or a DC / AC (Direct Current / Alternating Current-Direct Current to Alternating Current) converter. Among them, the on-board charger is electrically connected to the AC charging socket 21, the power supply socket 22 and the battery connection socket 23. After the on-board charger converts the AC current provided by the external AC charging source, the on-board charger outputs electrical energy to the power battery pack through the battery connection socket 23, and the lead-acid battery is used to power the on-board charger, and the CAN network connection is used to output a charging control signal to the on-board charger so that the on-board charger can work normally.

[0079] The DC / DC converter is electrically connected to the power supply socket 22, the lead-acid battery is used to power the DC / DC converter, and the CAN network connection is used to output a DC conversion control signal to the DC / DC converter so that the DC / DC converter can normally output DC power of the required voltage.

[0080] The PDU controller is electrically connected to the AC charging socket 21 , the power supply socket 22 and the battery connection socket 23 , and is used to control the power distribution of the vehicle 1000 .

[0081] The DC / AC converter is electrically connected to the AC charging socket 21 and the power supply socket 22. The lead-acid battery is used to power the DC / AC converter. The CAN network connection is used to output an AC conversion control signal to the DC / AC converter so that the DC / AC converter can work normally. The DC / AC converter is used to convert the DC power input into the charging and distribution box 100 into AC power to provide it to electrical appliances.

[0082] It should be understood that the charging and distribution units that can be installed in the box 1 include but are not limited to the above four charging and distribution units. The user can set a suitable charging and distribution unit in the box 1 according to the actual needs of the vehicle 1000 to meet the charging and power requirements of the vehicle 1000.

[0083] According to some specific embodiments of the present application, the fixing bolts of the distribution socket 2 can be fixed to the distribution socket 2 by a riveting and welding process, and a sealing ring is provided between the distribution socket 2 and the box body 1. Such a setting can improve the sealing effect of the charging and distribution box 100 at the distribution socket 2.

[0084] like Figure 8 As shown, in some embodiments of the present application, there are multiple power distribution sockets 2, and the multiple power distribution sockets 2 include at least two of the AC charging socket 21, the power supply socket 22, and the battery connection socket 23. The AC charging socket 21, the power supply socket 22, and the battery connection socket 23 are all arranged on the same side wall of the box body 1. When the AC charging harness in the vehicle 1000 is connected to the AC charging socket 21, the power supply harness is connected to the power supply socket 22, or the battery connection socket 23 is connected to the battery connection harness, such an arrangement can make the AC charging harness outlet direction, the power supply harness outlet direction, and the battery connection harness outlet direction of the charging and distribution box 100 the same. After the charging and distribution box 100 is assembled to the vehicle body 200, the wiring harness arrangement of the vehicle 1000 is more concise, and the assembler can simultaneously organize multiple harnesses with the same outlet direction of the charging and distribution box 100, thereby reducing the difficulty of wiring in the vehicle 1000.

[0085] Furthermore, if Figure 8 As shown, according to the embodiment of the present application, the charging and distribution box 100 may also include: a heat exchanger (not shown in the figure), the heat exchanger is arranged in the box body 1, and the outer wall of the box body 1 may also be provided with a refrigerant interface 16, the refrigerant interface 16 is connected to the heat exchanger, and the refrigerant interface 16 is used to connect to the refrigerant pipeline. The refrigerant can flow between the refrigerant pipeline and the heat exchanger through the refrigerant interface 16, and the refrigerant exchanges heat with the electrical components in the box body 1 when flowing through the heat exchanger.

[0086] In addition, the refrigerant interface 16, the AC charging socket 21, the power supply socket 22 and the battery connection socket 23 are arranged on the same side wall of the box body 1, so that the outlet direction of the refrigerant pipeline, the outlet direction of the AC charging harness, the outlet direction of the power supply harness and the outlet direction of the battery connection harness of the charging and distribution box 100 can be the same. After the charging and distribution box 100 is assembled to the vehicle body 200, the wiring harness layout and pipeline layout of the vehicle 1000 are simpler, and the assembler can simultaneously organize multiple outlet directions and wiring harnesses and pipelines with the same outlet direction of the charging and distribution box 100, thereby reducing the difficulty of wiring and pipe laying of the vehicle 1000.

[0087] Furthermore, the refrigerant interface 16 can be constructed as a quick-connect interface, and the refrigerant interface 16 can be plugged into and matched with the refrigerant pipeline to reduce the difficulty of connecting the refrigerant interface 16 and the refrigerant pipeline.

[0088] like Figure 8 , Fig. 9 As shown, in some embodiments of the present application, the outer side wall of the box body 1 may also be provided with a 12V positive wire mounting seat 6, the 12V positive wire mounting seat 6 is electrically connected to the corresponding charging and distribution unit, and the 12V positive wire mounting seat 6 and the distribution socket 2 are provided on different side walls of the box body 1. Specifically, when a DC / DC converter is provided in the charging and distribution box 100, the 12V positive wire mounting seat 6 is electrically connected to the DC / DC converter, the 12V positive wire mounting seat 6 is electrically connected to the lead-acid battery, and the DC / DC converter supplies power to the lead-acid battery through the 12V positive wire mounting seat 6 to balance the power consumption of the lead-acid battery. Among them, in order to make the DC / DC converter supply power to the lead-acid battery normally and avoid feeding the lead-acid battery, the 12V positive line has higher insulation requirements. When the outer wall of the box body 1 is simultaneously provided with a distribution socket 2 and a 12V positive line mounting seat 6, by arranging the 12V positive line mounting seat 6 and the distribution socket 2 on different side walls of the box body 1, the contact between the 12V positive line and other electrical connection harnesses can be avoided as much as possible, thereby reducing the risk of short circuit between the 12V positive line and other electrical connection harnesses, thereby improving the power safety of the vehicle 1000.

[0089] like Figure 8 , Fig. 9 As shown, in some embodiments of the present application, the 12V positive wire mounting seat 6 is provided with a harness mounting hole 61, a fastener mounting hole 62 and an insulating plate 63. The harness mounting hole 61 and the fastener mounting hole 62 are spaced apart. The harness mounting hole 61 is used to install the 12V positive wire, and a second fastener 52 is installed in the fastener mounting hole 62. The second fastener 52 can be a bolt, which passes through the fastener mounting hole 62 and the side wall of the box 1 to fix the 12V positive wire mounting seat 6 to the outer side wall of the box 1, so as to reduce the installation cost and difficulty between the 12V positive wire mounting seat 6 and the box 1.

[0090] By spacing the harness mounting hole 61 and the fastener mounting hole 62 apart, the 12V positive line can be avoided from contacting the second fastener 52 as much as possible, thereby reducing the risk of short circuit between the 12V positive line and the vehicle body 200, thereby improving the power safety of the vehicle 1000.

[0091] And, if Fig. 9 As shown, the insulating plate 63 is arranged between the harness mounting hole 61 and the fastener mounting hole 62 to separate the 12V positive wire from the second fastener 52. The insulating plate 63, the harness mounting hole 61 and the fastener mounting hole 62 are all arranged on the same side of the 12V positive wire mounting seat 6, and the insulating plate 63 extends in a direction away from the 12V positive wire mounting seat 6. The insulating plate 63 is made of insulating material. By arranging the insulating plate 63 between the harness mounting hole 61 and the fastener mounting hole 62, the 12V positive wire can be further prevented from contacting the second fastener 52, thereby further reducing the risk of short circuit between the 12V positive wire and the vehicle body 200, thereby improving the power safety of the vehicle 1000.

[0092] like Figure 2 , Figure 8 , Fig.10 As shown, in some embodiments of the present application, the box body 1 includes a box body 13 and a cover body 14, the box body 13 and the cover body 14 together define an installation space 11, and the box body 13 has an open mouth 15. Figure 2 In the embodiment shown, the box body 13 is arranged along the height direction (i.e. Figure 2 The cover 14 is provided on the opening 15, and the cover 14 is used to open or close the installation space 11, so that the assembler can install the charging and distribution unit in the installation space 11 or take the charging and distribution unit out of the installation space 11. In some preferred embodiments, the box body 13 and the cover 14 can be constructed of aluminum alloy parts to effectively reduce the weight of the charging and distribution box 100.

[0093] A support beam 7 may be provided in the box body 13. The support beam 7 is supported between two opposite inner side walls of the box body 13. Fig.10 In the illustrated embodiment, the support beam 7 is extended along the length direction of the charging and distribution box 100, and the support beam 7 is supported between the front inner wall and the rear inner wall of the box body 13. Of course, in some embodiments, the support beam 7 can also be extended along the width direction of the charging and distribution box 100, and the support beam 7 is supported between the left inner wall and the right inner wall of the box body 13. In other embodiments, multiple support beams 7 are cross-arranged in the charging and distribution box 100. The support beam 7 is used to support the box body 13, which can improve the structural strength of the box body 13, thereby minimizing the torsional deformation of the box body 13 after collision, and further improving the working reliability of the charging and distribution box 100.

[0094] And, if Fig.11 As shown, the support beam 7 has a cover support portion 71, and the cover support portion 71 is in abutment with the cover 14. Among them, the support beam 7 can use the cover support portion 71 to support the cover 14, which can avoid the cover 14 from being easily deformed due to the excessive structural size of the cover 14, thereby reducing the noise generated after the cover 14 is assembled to avoid the box, and further improving the NVH (Noise, Vibration, Harshness) performance of the vehicle 1000. In some specific embodiments, the cover support portion 71 can be constructed as a support block, so that the contact area between the cover support portion 71 and the support beam 7 and between the cover support portion 71 and the cover 14 can be increased, and the contact between the cover support portion 71 and the cover 14 is more reliable, thereby improving the support effect of the support beam 7 on the cover 14.

[0095] like Fig.10 As shown, in some embodiments of the present application, the side wall of the open mouth 15 of the box body 13 may be provided with a plurality of first positioning structures 81, and the plurality of first positioning structures 81 are arranged spaced apart along the circumferential direction of the box body 13. Fig.10 In the illustrated embodiment, the side wall of the open opening 15 of the box body 13 may be provided with two first positioning structures 81, and the two first positioning structures 81 are arranged along the diagonal line of the box body 1. Of course, in other embodiments, the two first positioning structures 81 may also be symmetrically distributed on both sides of the box body 1. And the number of the first positioning structures 81 is not limited to two. In some embodiments, the number of the first positioning structures 81 on the box body 13 may be three, four or more.

[0096] The cover body 14 is provided with a plurality of second positioning structures 82, and the first positioning structure 81 is positioned and matched with the second positioning structure 82. In the process of assembling the charging and distribution box 100, the assembler can quickly position and accurately align the cover body 14 and the box body 13 by positioning and matching the plurality of first positioning structures 81 and the second positioning structures 82, thereby improving the assembly efficiency of the charging and distribution box 100, and also improving the assembly accuracy of the charging and distribution box 100, and further improving the product quality of the charging and distribution box 100.

[0097] Further, one of the first positioning structure 81 and the second positioning structure 82 is a positioning column, and the other is a positioning hole. That is, the first positioning structure 81 can be a positioning hole, and the second positioning structure 82 can be a positioning column, or Fig.10As shown, the first positioning structure 81 can be a positioning column, and the second positioning structure 82 can be a positioning hole. By inserting the positioning column into the positioning hole, the inner wall of the positioning hole interferes with the outer peripheral wall of the positioning column, and the positioning column can be restricted from moving in the radial direction of the charging and distribution box 100, so that the technical effect of the first positioning structure 81 and the second positioning structure 82 can be achieved.

[0098] According to the charging and distribution box 100 of the embodiment of the present application, the side wall of the open mouth 15 of the box body 13 may also be provided with an annular sealing ring, which is clamped between the box body 13 and the cover body 14. The sealing ring is used to seal the gap between the box body 13 and the cover body 14, which can effectively ensure the sealing of the box body 1. The sealing ring can limit the liquid from penetrating into the box body 1 through the gap between the box body 13 and the cover body 14 as much as possible, thereby effectively improving the safety of the charging and distribution box 100.

[0099] like Figure 4 , Figure 8 As shown, in some embodiments of the present application, the outer wall of the box body 1 may also be provided with a breathable valve 9, and the breathable valve 9 is connected to the installation space 11. When the charging and distribution unit in the box body 1 generates heat during operation, causing the air in the box body 1 to heat up and expand, the air can be discharged to the outside of the box body 1 through the breathable valve 9, thereby reducing the pressure in the box body 1 and making the pressure inside and outside the box body 1 consistent. In addition, when the charging and distribution box 100 is collided and squeezed, the air in the box body 1 can be quickly discharged to the outside of the box body 1 through the breathable valve 9, which can avoid the excessive air pressure in the box body 1 causing secondary damage to the charging and distribution unit, thereby improving the reliability of the charging and distribution box 100.

[0100] Based on this, the present application further discloses a vehicle 1000. The vehicle 1000 according to the embodiment of the present application includes: a vehicle body 200 and a charging and distribution box 100. The outer wall surface of the vehicle body 200 is provided with a connection gap 240, and the connection gap 240 can be formed by the clamping portion 211 of the clip 210 in the above embodiment and the outer wall surface of the vehicle body 200. The charging and distribution box 100 is the charging and distribution box 100 described in the above embodiment, and one of the first connection structure 3 and the second connection structure 4 of the charging and distribution box 100 is inserted and limited in the connection gap 240 of the vehicle body 200, and the other is fixedly connected to the vehicle body 200.

[0101] According to the vehicle 1000 described in the embodiment of the present application, the assembler first inserts one of the first connection structure 3 and the second connection structure 4 that matches the connection gap 240 into the connection gap 240, and then fixes the other one to the vehicle body 200, so as to complete the assembly of the charging and distribution box 100 on the vehicle body 200. Compared with the prior art, the number of fasteners required to assemble when fixing the charging and distribution box 100 to the vehicle body 200 can be reduced, the installation efficiency of the charging and distribution box 100 on the vehicle body 200 is improved, and the assembly time of the vehicle 1000 is reduced. In addition, one side of the charging and distribution box 100 is fixed to the vehicle body 200 by plugging, and no installation tools are required when the charging and distribution box 100 is plugged and matched with the vehicle body 200, thereby reducing the size of the space on the vehicle body 200 for avoiding the installation tools.

[0102] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present application. These improvements and substitutions should also be regarded as the scope of protection of the present application.
