Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a vehicle charging and distribution box for a vehicle. Background Technology

[0002] The vehicle manages its power consumption and charging through the charging and distribution box. In order to adapt the charging and distribution box to different types of high-voltage architectures of the vehicle and meet the overall vehicle layout requirements, the charging and distribution box is installed on the vehicle body, and the charging and distribution box is located in the front compartment outside the passenger compartment or under the vehicle seats.

[0003] In existing technologies, charging and distribution boxes have multiple fasteners along their circumference. Assembly personnel sequentially tighten these fasteners to secure the box to the vehicle body. For compact vehicles, the assembly space for the charging and distribution box is limited, making it difficult for assembly personnel to access the fasteners with their tools. This reduces installation efficiency and prolongs assembly time. Furthermore, a significant amount of space is required on the vehicle body to accommodate the installation tools, increasing the size of the charging and distribution box and reducing space utilization within the vehicle.

[0049] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.

[0050] This application discloses a charging and distribution box 100 for a vehicle 1000 and the vehicle 1000 itself. The charging and distribution box 100 is disposed in the vehicle 1000 and is used to manage the charging and power consumption of the vehicle 1000. The vehicle 1000 also includes a body 200, and the charging and distribution box 100 is mounted on the body 200.

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

[0052] The installation space 11 is used to accommodate components. The power distribution socket 2 is adapted to connect and mate with the electrical connector plug of the wiring harness. Furthermore, a charging and distribution unit assembly is located within the housing 1. This assembly includes at least one type of charging and distribution unit, which is electrically connected to its corresponding power distribution socket 2. In other words, the charging and distribution unit is electrically connected to the wiring harness via the power distribution socket 2, and consequently, to the electrical components at the other end of the wiring harness. By increasing the types of charging and distribution units within the housing 1, the functionality of the charging and distribution box 100 can be enhanced.

[0053] Furthermore, both the first connecting structure 3 and the second connecting structure 4 are disposed on the outer side wall of the housing 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, i.e. Figure 2 The first direction of the charging and distribution box 100 can refer to the front-to-back direction. However, this application is not limited to this. In some other embodiments, the first direction of the charging and distribution box 100 can refer to the width direction of the charging and distribution box 100, that is... Figure 2 The left and right directions in the middle.

[0054] Meanwhile, the vehicle body 200 is provided with a connection gap 240. One of the first connecting structure 3 and the second connecting structure 4 is adapted to be inserted into and confined within the connection gap 240 of the vehicle body 200, and the other is adapted to be fixedly connected to the vehicle body 200. That is, the first connecting structure 3 is adapted to be inserted into and confined within the connection gap 240 of the vehicle body 200, and the second connecting structure 4 is fixedly connected to the vehicle body 200, or the second connecting structure 4 is adapted to be inserted into and confined within the connection gap 240 of the vehicle body 200, and the first connecting structure 3 is fixedly connected to the vehicle body 200. It should be noted that the one of the first connecting structure 3 and the second connecting 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] During the assembly process of the charging and distribution box 100 onto the vehicle 1000, the assembler first inserts one of the first connecting structures 3 and the second connecting structure 4 corresponding to the connecting gap 240 into the connecting gap 240. The two opposing surfaces of the connecting gap 240 together limit the connection structure (i.e., the first connecting structure 3 or the second connecting structure 4), preventing further movement of the one corresponding to the connecting gap 240. This allows the side of the box 1 closest to the connecting gap 240 to be fixed to the vehicle body 200. Then, the assembler fixes one of the first connecting structures 3 and the second connecting structure 4 that is not connected to the vehicle body 200 to the vehicle body 200, thus fixing the other side of the box 1 to the vehicle body 200. At this point, both sides of the box 1 are fixed to the vehicle body 200, completing the assembly process of the charging and distribution box 100 onto the vehicle body 200.

[0056] Therefore, the assembler first inserts one of the first connecting structure 3 and the second connecting structure 4, which mates with the connecting gap 240, into the connecting gap 240, and then fixes the other to the vehicle body 200. This completes the assembly of the charging and distribution box 100 onto the vehicle body 200. Compared with the prior art, the insertion and mating of one of the first connecting structure 3 and the second connecting structure 4 into the vehicle body 200 reduces the number of fasteners required to fix the charging and distribution box 100 to the vehicle body 200, improves the installation efficiency of the charging and distribution box 100 on the vehicle body 200, and reduces the assembly time of the vehicle 1000. Furthermore, no installation tools are required when the charging and distribution box 100 is inserted and mated with the vehicle body 200, thereby reducing the space required on the vehicle body 200 to accommodate 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 and rear direction of the vehicle 1000. In other words, the charging and distribution box 100 can be set with a specific installation direction according to the actual structure of the vehicle body 200, so that the assembly personnel can fix the charging and distribution box 100 to the vehicle body 200.

[0058] like Figures 1-3 , Figures 5-7 As shown, in some embodiments of this application, a clip 210 is provided on the outer wall surface of the vehicle body 200. The clip 210 includes a clamping part 211 and a connecting part 212. The clamping part 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 part 211 and the outer wall surface of the vehicle body 200 are spaced apart 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 vertical direction is as follows. The connecting part 212 is connected between the end of the clamping part 211 away from the box body 1 and the vehicle body 200. An opening communicating with the connecting gap 240 is formed between the clamping part 211 and the outer wall surface of the vehicle body 200, and the opening is open towards the box body 1.

[0059] Furthermore, the first connecting structure 3 is adapted to be inserted into the opening between the clamping part 211 and the outer wall surface of the vehicle body 200 and is confined within the connecting gap 240. The first connecting structure 3 includes a plug plate part 31, which is located along the first direction of the charging and distribution box 100 (i.e., Figure 1 Extending away from the housing 1 in the front-rear direction, the insert plate portion 31 is adapted to extend into the connecting gap 240 and be clamped between the clamping portion 211 and the outer wall surface of the vehicle body 200. By using the clamping portion 211 and the outer wall surface of the vehicle body 200 to clamp the insert plate portion 31, the clamping portion 211 and the outer wall surface of the vehicle body 200 can jointly restrict the movement of the insert plate portion 31 towards or away from the vehicle body 200. Thus, the insert plate portion 31 can restrict the movement of one side of the charging and distribution box 100 towards or away from the vehicle body 200 through the first connecting 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 is elastically deformable, and the clamping part 211 can rotate around the connection between the clamping part 211 and the connecting part 212. When the insert plate part 31 is inserted between the clamping part 211 and the outer wall surface of the vehicle body 200, the insert plate part 31 can drive the clamping part 211 to separate from the outer wall surface of the vehicle body 200. The clamping part 211 rotates relative to the connecting part 212, and the clip 210 undergoes elastic deformation and generates elastic force. The elastic force of the clamping part 211 acts on the insert plate part 31, which can reliably clamp the insert plate part 31 between the clamping part 211 and the outer wall surface of the vehicle body 200. This can minimize the possibility of the side of the charging and distribution box 100 with the insert plate part 31 becoming loose 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 implementation schemes, such as Figures 5-7As shown, the outer wall of the vehicle body 200 is also provided with a limiting baffle 230. The limiting baffle 230 is adjacent to the connecting part 212. When the insert plate part 31 is inserted between the clamping part 211 and the outer wall of the vehicle body 200, the limiting baffle 230 is located outside the insert plate part 31. The limiting baffle 230 is adapted to stop and cooperate with the insert plate part 31. The limiting baffle 230 is used to restrict the insert plate part 31 from moving in the radial direction of the charging and distribution box 100. It can prevent the insert plate part 31 from coming out of the connecting 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, such as Figures 3-6 As shown, the plug-in section 31 and the housing 1 are aligned along the first direction of the charging and distribution box 100 (i.e., Figure 1 The first connecting structure 3, which is arranged in a front-to-back direction, also includes a first connecting part 32. The first connecting part 32 is connected between the insert plate part 31 and the housing 1, and the first connecting part 32 is detachably connected to the insert plate part 31. Specifically, one end of the first connecting part 32 is fixedly connected to the outer side wall of the housing 1. The end of the first connecting part 32 near the insert plate part 31 is provided with a positioning groove 321 and a fixing groove 322. The insert plate part 31 is provided with a positioning slider and a fixing post. After the insert plate part 31 is positioned and engaged with the positioning groove 321 by the positioning slider, the first connecting part 32 can be connected to the insert plate part 31 by extending the fixing post into the fixing groove 322.

[0063] By detachably connecting the first connecting part 32 and the insert part 31, the assembler can design a suitable connecting gap 240 on the body 200 according to the type and model of the vehicle 1000. Then, according to the size of the connecting gap 240, a matching insert part 31 is selected and connected to the first connecting part 32. This allows the first connecting structure 3 to be compatible with the body 200 of different vehicle models, 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 Figures 4-6 As shown, in some embodiments of this application, along the second direction of the charging and distribution box 100, at least one side wall of the first connecting portion 32 may be provided with a reinforcing block 33, which is fixedly connected to the outer side wall of the box body 1. The first direction of the charging and distribution box 100 is perpendicular to the second direction. Figure 1 When the front and rear directions are in the middle, the second direction of the charging and distribution box 100 is Figure 1 The left and right directions in the middle.

[0065] The reinforcing block 33 is used to improve the structural strength of the first connecting part 32. Specifically, the first connecting part 32 can be constructed as a bent plate, which enables the first connecting structure 3 to have good fracture resistance. The reinforcing block 33 and the first connecting part 32 form a triangular stable structure. The reinforcing block 33 can limit the change of bending angle of the first connecting part 32, making the first connecting structure 3 less prone to deformation, thereby improving the structural strength of the first connecting structure 3.

[0066] In some preferred embodiments, reinforcing blocks 33 are provided on both side walls of the first connecting portion 32, which can effectively improve the structural strength of the first connecting structure 3. Furthermore, the reinforcing blocks 33 are fixedly connected to the outer side wall of the housing 1, thus forming a force transmission path between the reinforcing blocks 33 and the housing 1. The housing 1 can support the reinforcing blocks 33, thereby making the reinforcing blocks 33 more effective in improving the structural strength of the first connecting structure 3.

[0067] like Figure 1 , Figure 4 , Figure 6 As shown in some embodiments of this application, the outer wall of the housing 1, where the first connecting structure 3 is located, is also provided with a support strip 12. The support strip 12 extends along the second direction of the charging and distribution box 100 and passes through the reinforcing block 33. The bottom wall of the reinforcing block 33 opposite to the vehicle body 200 may be provided with a clearance groove 34, which is used to avoid the support strip 12. The support strip 12 is used to improve the structural strength of the housing 1. When the first connecting structure 3 is impacted and rotates around the housing 1, the support strip 12 can minimize the torsional deformation of the housing 1. Furthermore, the support strip 12 can support the reinforcing block 33, minimizing the rotational deformation of the reinforcing block 33.

[0068] like Figure 6 , Figure 7 As shown, in some embodiments of this application, the end of the clamping part 211 near the housing 1 may be provided with a guide part 213. The guide part 213 is bent away from the outer wall surface, and the reinforcing block 33 is adapted to abut against the guide part 213. When the insert plate part 31 is inserted into the clamping part 211 and the outer wall surface of the vehicle body 200, when the reinforcing block 33 abuts against the guide part 213, the guide part 213 can restrict the reinforcing block 33 from continuing to move closer to the installation gap, proving that the insert plate part 31 has been installed in place within the installation gap. The guide part 213 can limit the position of the insert plate part 31 within the installation gap, thereby avoiding insufficient or excessive length of the insert plate part 31 extending into the installation gap, and thus 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 structure of the guide portion 213 opposite to the insert plate portion 31 is a guide slope. The guide slope can guide the insert plate portion 31, thereby facilitating the insertion of the insert plate portion 31 into the installation gap and further reducing the installation difficulty of the first connecting structure 3.

[0070] like Figures 1-4 , Figure 8 As shown, in some embodiments of this application, when the first connecting structure 3 is adapted to be inserted into and confined within the connecting gap 240 of the vehicle body 200, the second connecting structure 4 is adapted to be 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 connecting structure 4 includes a second mounting portion 41, which is adapted to be disposed opposite to the first mounting portion 220. A first fastener 51 passes through the first mounting portion 220 and the second mounting portion 41 to fix the first connecting structure 3 and the vehicle body 200.

[0071] Both the first mounting portion 220 and the second mounting portion 41 may be provided with connecting holes. The first fastener 51 may be a bolt. When the connecting hole of the first mounting portion 220 is aligned with the connecting 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 connecting structure 4 and the vehicle body 200. Thus, the second connecting structure 4 can fix the housing 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 embodiment of the present application, the charging and distribution box 100 has a conductive layer on the surface of the second mounting part 41 opposite to the vehicle body 200. The conductive layer can be formed by coating the outer surface of the second mounting part 41 with conductive paint. 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, this arrangement can eliminate the need to install a grounding wire in the charging and distribution box 100, thereby reducing the manufacturing cost of the charging and distribution box 100.

[0073] Furthermore, such as Figures 1-4 As shown, the second mounting part 41 and the housing 1 are along the first direction of the charging and distribution box 100 (i.e., Figure 1The second connecting structure 4, which is spaced apart in the front and rear directions, also includes a second connecting part 42. The second connecting part 42 connects the second mounting part 41 and the housing 1, and the end of the second connecting part 42 near the second mounting part 41 is inclined towards the vehicle body 200. The second connecting part 42 can be constructed as a connecting plate. By connecting the connecting plate inclined between the second mounting part 41 and the housing 1, it can be ensured that the second mounting part 41 fits snugly against the vehicle body 200, while the distance between the housing 1 and the vehicle body 200 meets the design requirements.

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

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

[0076] In some preferred embodiments, reinforcing plates 43 are provided on both side walls of the second connecting structure 4, which can effectively improve the structural strength of the second connecting structure 4. Furthermore, the reinforcing plates 43 are fixedly connected to the outer side wall of the housing 1, thus forming a force transmission path between the reinforcing plates 43 and the housing 1. The housing 1 can support the reinforcing plates 43, thereby making the reinforcing plates 43 more effective in improving the structural strength of the second connecting structure 4.

[0077] In some embodiments of this application, the power distribution socket 2 includes: an AC charging socket 21, a power supply socket 22, or a battery connection socket 23. The AC charging socket 21 is used for electrical connection to an external AC charging power source, which 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. The lead-acid battery provides 9V to 16V current to the charging and distribution box 100, and the CAN network transmits charging or power distribution signals to the charging and distribution box 100. The battery connection socket 23 is used for electrical connection to a power battery pack, enabling the transfer of electrical energy between the charging and distribution box 100 and the power battery pack. Preferably, the charging and distribution box 100 can simultaneously be equipped with an AC charging socket 21, a power supply socket 22, and a battery connection socket 23, thereby improving the functionality of the charging and distribution box 100.

[0078] Based on this, the charging and power distribution unit can be an on-board charger, a DC / DC (Direct Current / Direct Current) converter, a PDU (Power Distribution Unit) controller, or a DC / AC (Direct Current / Alternating Current) converter. 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 converting 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. Furthermore, the lead-acid battery supplies power to the on-board charger, and the CAN network connection is used to output charging control signals to the on-board charger to ensure its normal operation.

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

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

[0081] The DC / AC converter is electrically connected to AC charging socket 21 and power supply socket 22. A lead-acid battery is used to power the DC / AC converter. A CAN network connection is used to output AC conversion control signals 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 to the charging and distribution box 100 into AC power for use by electrical appliances.

[0082] It should be understood that the charging and power distribution units that can be installed in the housing 1 include, but are not limited to, the above four types of charging and power distribution units. Users can set up appropriate charging and power distribution units in the housing 1 according to the actual needs of the vehicle 1000 to meet the charging and power consumption needs of the vehicle 1000.

[0083] According to some specific embodiments of this application, the fixing bolts of the power distribution socket 2 can be fixed to the power distribution socket 2 by a press-fit welding process, and a sealing ring is provided between the power distribution socket 2 and the box 1. This arrangement can improve the sealing effect of the charging and distribution box 100 at the power distribution socket 2.

[0084] like Figure 8 As shown, in some embodiments of this application, there are multiple power distribution sockets 2, including at least two of AC charging sockets 21, power supply sockets 22, and battery connection sockets 23. The AC charging sockets 21, power supply sockets 22, and battery connection sockets 23 are all located on the same side wall of the housing 1. When the AC charging harness inside the vehicle 1000 is connected to the AC charging socket 21, the power supply harness to the power supply socket 22, or the battery connection socket 23 to the battery connection harness, this arrangement ensures that 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 are all the same. After the charging and distribution box 100 is assembled onto the vehicle body 200, the wiring arrangement of the vehicle 100 is simpler, and the assembly personnel can simultaneously organize multiple wiring harnesses with the same outlet direction in the charging and distribution box 100, thereby reducing the difficulty of wiring management in the vehicle 1000.

[0085] Furthermore, such as Figure 8 As shown, the charging and distribution box 100 according to the embodiment of this application may further include: a heat exchanger (not shown in the figure), the heat exchanger is disposed inside the box 1, and the outer side wall of the box 1 may also be provided with a refrigerant interface 16, the refrigerant interface 16 is connected to the heat exchanger, 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 inside the box 1 when it flows through the heat exchanger.

[0086] Furthermore, the refrigerant interface 16, AC charging socket 21, power supply socket 22, and battery connection socket 23 are located on the same side wall of the housing 1. This allows the refrigerant pipe outlet direction, AC charging harness outlet direction, power supply harness outlet direction, and battery connection harness outlet direction of the charging and distribution box 100 to be the same. After the charging and distribution box 100 is assembled to the vehicle body 200, the wiring harness and pipe layout of the vehicle 1000 is simpler. Assembly personnel can simultaneously organize multiple outlet directions and wiring harnesses and pipes with the same outlet direction of the charging and distribution box 100, thereby reducing the difficulty of wiring and pipe laying in the vehicle 1000.

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

[0088] like Figure 8 , Figure 9 As shown, in some embodiments of this application, a 12V positive line mounting base 6 may also be provided on the outer wall of the enclosure 1. The 12V positive line mounting base 6 is electrically connected to the corresponding charging and distribution unit. The 12V positive line mounting base 6 and the power distribution socket 2 are located on different side walls of the enclosure 1. Specifically, when a DC / DC converter is provided inside the charging and distribution box 100, the 12V positive line mounting base 6 is electrically connected to the DC / DC converter and to the lead-acid battery. The DC / DC converter supplies power to the lead-acid battery through the 12V positive line mounting base 6 to balance the power consumption of the lead-acid battery. In order to ensure that the DC / DC converter can supply power to the lead-acid battery normally and avoid the lead-acid battery from being depleted, the 12V positive line has higher insulation requirements. When the outer side wall of the enclosure 1 is equipped with both the power distribution socket 2 and the 12V positive line mounting base 6, by setting the 12V positive line mounting base 6 and the power distribution socket 2 on different side walls of the enclosure 1, the contact between the 12V positive line and other electrical connection harnesses can be avoided as much as possible. This can reduce the risk of short circuit between the 12V positive line and other electrical connection harnesses, thereby improving the electrical safety of the vehicle 1000.

[0089] like Figure 8 , Figure 9 As shown, in some embodiments of this application, the 12V positive wire mounting base 6 is provided with a wire harness mounting hole 61, a fastener mounting hole 62, and an insulating plate 63. The wire harness mounting hole 61 and the fastener mounting hole 62 are spaced apart. The wire 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 housing 1 to fix the 12V positive wire mounting base 6 to the outer side wall of the housing 1. This reduces the installation cost and difficulty between the 12V positive wire mounting base 6 and the housing 1.

[0090] By spacing the wiring harness mounting hole 61 from the fastener mounting hole 62, contact between the 12V positive wire and the second fastener 52 can be minimized, thereby reducing the risk of a short circuit between the 12V positive wire and the vehicle body 200 and improving the electrical safety of the vehicle 1000.

[0091] And, as Figure 9 As shown, an insulating plate 63 is disposed between the wire harness mounting hole 61 and the fastener mounting hole 62 to separate the 12V positive wire and the second fastener 52. The insulating plate 63, the wire harness mounting hole 61, and the fastener mounting hole 62 are all located on the same side of the 12V positive wire mounting base 6, and the insulating plate 63 extends away from the 12V positive wire mounting base 6. The insulating plate 63 is made of insulating material. By placing the insulating plate 63 between the wire harness mounting hole 61 and the fastener mounting hole 62, contact between the 12V positive wire and the second fastener 52 can be further avoided, thereby further reducing the risk of a short circuit between the 12V positive wire and the vehicle body 200, and thus improving the electrical safety of the vehicle 1000.

[0092] like Figure 2 , Figure 8 , Figure 10 As shown, in some embodiments of this application, the housing 1 includes a housing body 13 and a cover 14, which together define an installation space 11. The housing body 13 has an opening 15. Figure 2 In the embodiment shown, the box body 13 is along the height direction of the charging and distribution box 100 (i.e., Figure 2 The charging and distribution box 100 is designed to open upwards (vertically). A cover 14 is placed over the opening 15. The cover 14 is used to open or close the installation space 11 to facilitate the installation personnel to install or remove the charging and distribution unit from the installation space 11. In some preferred embodiments, both the box body 13 and the cover 14 can be constructed of aluminum alloy to effectively reduce the weight of the charging and distribution box 100.

[0093] A support beam 7 can be provided inside the box body 13. The support beam 7 is supported between two opposite inner side walls of the box body 13, for example, in Figure 10 In the illustrated embodiment, the support beam 7 extends along the length of the charging and distribution box 100, and is supported between the front and rear inner walls of the box body 13. In some embodiments, the support beam 7 may also extend along the width of the charging and distribution box 100, and be supported between the left and right inner walls of the box body 13. In other embodiments, multiple support beams 7 are intersectingly arranged in the charging and distribution box 100. The support beams 7 support the box body 13, thereby increasing the structural strength of the box body 13 and minimizing torsional deformation after impact, thus improving the operational reliability of the charging and distribution box 100.

[0094] And, as Figure 11 As shown, the support beam 7 has a cover support portion 71, which engages with the cover 14. The support beam 7 utilizes the cover support portion 71 to support the cover 14, minimizing the risk of deformation due to the cover 14's excessive size. This reduces noise generated during cover assembly and improves 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, increasing 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. This makes the contact between the cover support portion 71 and the cover 14 more reliable, thereby enhancing the support effect of the support beam 7 on the cover 14.

[0095] like Figure 10 As shown, in some embodiments of this application, the sidewall of the opening 15 of the box body 13 may be provided with a plurality of first positioning structures 81, which are spaced apart along the circumferential direction of the box body 13. Figure 10 In the illustrated embodiment, two first positioning structures 81 may be provided on the side wall of the opening 15 of the box body 13. The two first positioning structures 81 are arranged along the diagonal 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. Furthermore, the number of first positioning structures 81 is not limited to two. In some embodiments, the number of first positioning structures 81 on the box body 13 may be three, four, or more.

[0096] The cover 14 is provided with multiple second positioning structures 82, and the first positioning structure 81 and the second positioning structure 82 are positioned and engaged. During the assembly of the charging and distribution box 100, the assembler can quickly position and accurately align the cover 14 with the box body 13 by positioning and engaging multiple sets of first positioning structures 81 and second positioning structures 82, thereby improving the assembly efficiency and accuracy of the charging and distribution box 100, and ultimately improving the product quality of the charging and distribution box 100.

[0097] Furthermore, one of the first positioning structure 81 and the second positioning structure 82 is a positioning post, 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 post, or as... Figure 10As shown, the first positioning structure 81 can be a positioning post, and the second positioning structure 82 can be a positioning hole. By inserting the positioning post into the positioning hole, the inner wall of the positioning hole interferes with the outer peripheral wall of the positioning post, which can restrict the movement of the positioning post in the radial direction of the charging and distribution box 100, thereby achieving the technical effect of positioning and cooperating between the first positioning structure 81 and the second positioning structure 82.

[0098] According to the embodiment of the present application, the side wall of the opening 15 of the box body 13 can also be provided with an annular sealing ring. The sealing ring is sandwiched between the box body 13 and the cover 14. The sealing ring is used to seal the gap between the box body 13 and the cover 14, which can effectively ensure the sealing performance of the box body 1. The sealing ring can limit the liquid from seeping into the box body 1 from the gap between the box body 13 and the cover 14, which effectively improves the safety of the charging and distribution box 100.

[0099] like Figure 4 , Figure 8 As shown, in some embodiments of this application, a vent valve 9 may be provided on the outer wall of the housing 1, and the vent valve 9 is connected to the installation space 11. When the charging and distribution unit inside the housing 1 generates heat during operation, causing the air inside the housing 1 to heat up and expand, the air can be discharged to the outside of the housing 1 through the vent valve 9, thereby reducing the pressure inside the housing 1 and making the pressure inside and outside the housing 1 consistent. Furthermore, when the charging and distribution box 100 is subjected to collision and compression, the air inside the housing 1 can be quickly discharged to the outside of the housing 1 through the vent valve 9, which can minimize the risk of secondary damage to the charging and distribution unit due to excessive air pressure inside the housing 1, thereby improving the reliability of the charging and distribution box 100.

[0100] Based on this, this application further discloses a vehicle 1000, which, according to the embodiments of this 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, which can be formed jointly by the clamping portion 211 of the clip 210 in the above embodiments 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 embodiments. One of the first connecting structure 3 and the second connecting structure 4 of the charging and distribution box 100 is inserted into and confined within the connection gap 240 of the vehicle body 200, while the other is fixedly connected to the vehicle body 200.

[0101] According to the vehicle 1000 described in this application embodiment, the assembler first inserts one of the first connecting structure 3 and the second connecting structure 4, which mates with the connecting gap 240, into the connecting gap 240, and then fixes the other to the vehicle body 200. This completes the assembly of the charging and distribution box 100 on the vehicle body 200. Compared with the prior art, this reduces the number of fasteners required to fix the charging and distribution box 100 to the vehicle body 200, improves the installation efficiency of the charging and distribution box 100 on the vehicle body 200, and reduces the assembly time of the vehicle 1000. Furthermore, one side of the charging and distribution box 100 is fixed to the vehicle body 200 by a plug-in connection. No installation tools are required when the charging and distribution box 100 is plugged into the vehicle body 200, thereby reducing the space required on the vehicle body 200 to avoid installation tools.

[0102] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
