[0031] The following describes the detailed implementation manners of the present disclosure in conjunction with the accompanying drawings. It should be understood that the detailed implementation manners described herein are only for the purpose of illustration and explanation of the present disclosure, and are not used to limit the present disclosure.

[0032] In the present disclosure, unless otherwise stated, the orientation words such as "upper", "lower", "left", "right" and the like indicate the orientation or position relationship only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, specific orientation structure and operation. Therefore, it should not be construed as a limitation of the present disclosure. The terms "inner" and "outer" refer to the inside and outside of the corresponding structural contour.

[0033] In addition, it should be noted that the terms such as "first" and "second" are used to distinguish one element from another, and do not have sequence and importance. In addition, in the description with reference to the accompanying drawings, the same reference numerals in different drawings represent the same elements.

[0034] In the description of the present disclosure, it should also be noted that unless otherwise clearly specified and limited, the terms "set", "connected", "coupled", "installed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0035] Refer to Figures 1 to 4As shown, the first aspect of the present disclosure provides a high-voltage distribution box 1 for vehicles, including a box body 10, a side of the box body 10 close to the electric drive assembly is provided with a wiring terminal 40, and the wiring terminal 40 is arranged protruding from the outer wall of the box body 10; the end of the wiring terminal 40 away from the box body 10 is electrically connected to the output end of the electric drive assembly. Through the above technical scheme, on the one hand, the high-voltage distribution assembly is integrated into the above-mentioned high-voltage distribution box 1. When the relevant accessories in the above-mentioned high-voltage distribution box 1 are worn or damaged, it is not necessary to disassemble the battery pack or the front engine compartment, and the relevant accessories arranged in the high-voltage distribution box 1 can be repaired or replaced more directly and quickly, thereby greatly reducing the difficulty and cost of maintenance; on the other hand, the wiring terminal 40 protruding from the outer wall of the box body 10 can be quickly connected to the input end of the electric drive assembly, and the safety and reliability of the high-voltage distribution box 1 are also improved.

[0036] Furthermore, a housing cavity is formed in the box body 10, and a circuit protection component 20 is arranged in the housing cavity, and the wiring terminal 40 is electrically connected to the input end of the circuit protection component 20. In this way, when the circuit protection component 20 is worn out or ablated, since the circuit protection component 20 is arranged in the box body 10 independent of the electric drive assembly, it is convenient for maintenance personnel to quickly find the fault point, and to perform maintenance, maintenance, replacement and other operations on the circuit protection component 20 located in the housing cavity. The maintenance and replacement of the circuit protection component 20 will not be disturbed or interfered by the electric drive assembly, so there is no need to lift or disassemble the electric drive assembly as a whole, and the maintenance, maintenance and replacement of the circuit protection component 20 are simpler and more labor-saving, which can significantly reduce the maintenance time and maintenance cost.

[0037] In an exemplary embodiment provided by the present disclosure, Figure 3 As shown, the high-voltage distribution box 1 also includes a first fastener, a first fastening hole 41 may be formed on the wiring terminal 40, and a second fastening hole may be formed on the output end of the electric drive assembly, and the first fastener can be unlocked and locked in the first fastening hole 41 and the second fastening hole. In this way, the first fastener can be used to lock the wiring terminal 40 and the output end of the electric drive assembly, thereby improving the stability and firmness of the connection between the wiring terminal 40 and the electric drive assembly, and avoiding problems such as poor contact and circuit breakage between the wiring terminal 40 and the output end of the electric drive assembly due to shaking and bumping of the vehicle during driving.

[0038] In addition, in order to improve the connection stability between the high-voltage distribution box 1 and the electric drive assembly, as Figure 1 , Figure 2As shown, in an exemplary embodiment provided by the present disclosure, the high-voltage distribution box 1 may further include a plurality of fixing feet 50 and a plurality of second fasteners. Each fixing foot 50 is connected to the box body 10, and a third fastening hole 51 is formed on each fixing foot 50. The second fastener passes through the third fastening hole 51 and is lockably fastened in a preset fourth fastening hole on the electric drive assembly. In this way, the second fastener passes through the second fastening hole and the third fastening hole 51 in sequence, and the fixing foot 50 connected to the box body 10 can be locked on the electric drive assembly, thereby realizing the relative fixation between the high-voltage distribution box 1 and the electric drive assembly.

[0039] The present disclosure does not limit the specific detachable manner and structure between the high-voltage distribution box 1 and the electric drive assembly. The distribution box can also achieve detachable connection with the electric drive assembly by means of snap connection. For example, in another embodiment provided by the present disclosure, a snap block is formed on one of the high-voltage distribution box 1 and the electric drive assembly, and a snap buckle is formed on the other. The snap buckle can be unlockably snapped onto the snap block. In this way, when the snap buckle is snapped onto the snap block, the relative fixation between the high-voltage distribution box 1 and the electric drive assembly can be realized. When the snap buckle is disengaged from the snap block, the high-voltage distribution box 1 and the electric drive assembly are in an independent state, and at this time, the high-voltage distribution box 1 can be detached from the electric drive assembly. Moreover, by adopting the above-mentioned snap connection method, the high-voltage distribution box 1 can be quickly disassembled and assembled without the aid of tools, which is more convenient for the maintenance operation of maintenance personnel.

[0040] The present disclosure does not limit the specific setting position of the fixing foot 50. The fixing foot 50 can be connected to any position of the above-mentioned high-voltage distribution box 1 according to the specific installation situation. For example, in an exemplary embodiment provided by the present disclosure, as Figure 3 shown, the fixing foot 50 can be connected to the side wall of the box body 10, and the lower end surface of the fixing foot 50 is flush with the lower end surface of the bottom wall of the box body 10. In this way, since the lower end surface of the fixing foot 50 is flush with the lower end surface of the bottom wall of the box body 10, during the process of locking the fixing foot 50 on the electric drive assembly by the second fastener, the lower end surface of the fixing foot 50 and the lower end surface of the bottom wall are in the same plane, so that the fixing foot 50 and the bottom wall can be kept in close contact with the outside of the electric drive assembly at the same time, avoiding the problem that there is a large gap between the outer wall of the electric drive assembly and the fixing foot 50 or the bottom wall due to the height difference between the lower end surface of the fixing foot 50 and the lower end surface of the bottom wall, and further improving the connection stability between the high-voltage distribution box 1 and the electric drive assembly.

[0041] Furthermore, as Figure 3As shown, a protruding block 11 protruding outward is formed on the lower end surface of the box body 10. The wiring terminal 40 is inserted into the protruding block 11 and at least partially located outside the protruding block 11. The protruding block 11 is used to be clamped in a preset clamping groove on the electric drive assembly. In this way, during the process of assembling the box body 10 to the electric drive assembly, the protruding block 11 can be first aligned with the preset clamping groove on the electric drive assembly, and the protruding block 11 is inserted into the clamping groove. After the protruding block 11 is clamped in place, the first fastener is used to firmly connect the wiring terminal 40 and the output end of the electric drive assembly. During the above assembly process, on the one hand, during the process of installing the box body 10 on the electric drive assembly, the protruding block 11 and the clamping groove can also play a role in guiding and positioning the box body 10, that is, directly inserting the protruding block 11 located on the lower end surface of the box body 10 into the preset clamping groove on the electric drive assembly can realize the positioning of the assembly position of the box body 10, making the installation of the box body 10 simpler and more convenient, reducing the assembly difficulty, and further shortening the assembly time; on the other hand, under the interaction of the protruding block 11 and the clamping groove, the protruding block 11 and the clamping groove can limit and stop each other, thereby restricting the relative displacement between the box body 10 and the electric drive assembly and improving the connection stability between the box body 10 and the electric drive assembly.

[0042] The present disclosure does not limit the specific circuit connection relationship of the above circuit protection component 20. For example, in an exemplary embodiment provided by the present disclosure, as Figure 4 shown, the high-voltage output terminal 21 of the above circuit protection component 20 is used to connect to the load of the vehicle. The circuit protection component 20 includes a fuse 22 and / or a relay 23. The fuse 22 and / or the relay 23 are used to disconnect or conduct the circuit between the input end of the circuit protection component 20 and the high-voltage output terminal 21 of the circuit protection component 20. In this way, during the operation of the above circuit protection component 20, both the fuse 22 and / or the relay 23 can protect the circuit by controlling the on / off of the circuit. And when the above fuse 22 and / or relay 23 are damaged or consumed, the box body 10 can be directly opened to repair or replace the fuse 22 and / or the relay 23, thereby reducing the maintenance difficulty and maintenance cost while improving the maintenance efficiency.

[0043] Furthermore, as Figure 4As shown, the circuit protection component 20 may further include a voltage adjustment module 24 and a low-voltage connector 25. The voltage adjustment module 24 is connected between the output end of the circuit protection component 20 and the fuse 22 and / or the relay 23. The voltage adjustment module 24 is connected in series with the low-voltage connector 25. One end of the low-voltage connector 25 facing away from the box body 10 is used for electrically connecting to a low-voltage electrical device of the vehicle. In this way, a part of the current delivered from the electric drive assembly can be adjusted by the voltage adjustment module 24 to a low-voltage current with a lower voltage and flow out from the low-voltage connector 25, so as to provide power for the low-voltage electrical devices of the vehicle, such as the vehicle controller; at the same time, another part of the current delivered from the electric drive assembly can provide power for the load devices of the vehicle, such as the PTC heater, etc., via the high-voltage output terminal 21.

[0044] Optionally, as Figure 1 shown, the high-voltage distribution box 1 further includes a high-voltage load cable 60, a high-voltage power distribution cable 70, a high-voltage load line connector 80, and a high-voltage power distribution line connector 90. A first wiring terminal 12 and a second wiring terminal 13 are formed on the side wall of the box body 10. A first through hole for the high-voltage load cable 60 to pass through is provided in the first wiring terminal 12, and a second through hole for the high-voltage power distribution cable 70 to pass through is provided in the second wiring terminal 13. The first ends of the high-voltage load cable 60 and the high-voltage power distribution cable 70 are respectively electrically connected to the circuit protection component 20. The second end of the high-voltage load cable 60 is electrically connected to the high-voltage load line connector 80, and the second end of the high-voltage power distribution cable 70 is electrically connected to the high-voltage power distribution line connector 90. Specifically, during actual use, the high-voltage load cable 60 can be passed through the first through hole so that the first end of the high-voltage load cable 60 is electrically connected to the circuit protection component 20 located inside the box body 10, and electrical connection with the load device of the vehicle is achieved through the high-voltage power distribution line connector 90. The wiring terminal 40 is electrically connected to the output end of the electric drive assembly. Finally, the high-voltage load cable 60 is passed through the second through hole again so that the high-voltage load cable 60 is electrically connected to the circuit protection component 20 located inside the box body 10, and then electrical connection with the load device is achieved through the high-voltage load line connector 80.

[0045] The above-mentioned load device can be a compressor or a PTC heater. The present disclosure does not limit this. For embodiments where there are multiple load devices, the above-mentioned high-voltage load cables 60 and high-voltage load line connectors 80 also correspond to multiple ones, that is, each load device is arranged in one-to-one correspondence with each high-voltage load cable 60 and high-voltage load line connector 80.

[0046] Both the above-mentioned high-voltage load line connector 80 and high-voltage power distribution line connector 90 can be quick-connect plugs. The high-voltage load line connector 80 can be quickly installed and disassembled by plugging into the socket on the load device. Similarly, the high-voltage power distribution line connector 90 can also be quickly installed and disassembled by plugging into the socket on the battery pack.

[0047] In addition, the circuit protection component 20 provided by the present disclosure is not limited to being connected to the above-mentioned load device and battery pack. The circuit protection component 20 can be connected to any electrical equipment with relevant requirements. Based on this, as Figure 1 、 Figure 2 shown, a reserved wiring terminal 14 is further formed on the side wall of the high-voltage distribution box 1 provided by the present disclosure. The reserved wiring terminal 14 has a reserved through hole for the wire harness to pass through. In this way, when a new component needs to be reconnected, the cable can be electrically connected to the circuit protection component 20 located inside the box body 10 through the reserved through hole, and the structure of the box body 10 does not need to be rebuilt to achieve the electrical connection between the electrical equipment and the circuit protection component 20 inside the box body 10.

[0048] Optionally, as Figure 1 shown, the high-voltage distribution box 1 can further include a high-voltage load cable positioning member 61 and a high-voltage power distribution cable positioning member 71. The high-voltage load cable positioning member 61 is sleeved on the high-voltage load cable 60 and is used to lock the high-voltage load cable 60 on the electric drive assembly. The high-voltage power distribution cable positioning member 71 is sleeved on the high-voltage power distribution cable 70 and is used to lock the high-voltage power distribution cable 70 on the electric drive assembly. Through the high-voltage load cable positioning member 61, the positioning of the high-voltage load cable 60 and the adjustment of its routing can be achieved. Through the high-voltage power distribution cable positioning member 71, the positioning of the high-voltage power distribution cable 70 and the adjustment of its routing can be achieved, making the routing of the high-voltage load cable 60 and the high-voltage power distribution cable 70 more neat and orderly, being able to make rational use of space and avoiding interference with other components of the electric drive assembly.

[0049] The present disclosure does not limit the specific structures and fixing methods of the above-mentioned high-voltage load cable positioning member 61 and high-voltage power distribution cable positioning member 71, as long as the above-mentioned cables can be fastened on the electric drive assembly. In an exemplary embodiment provided by the present disclosure, the above-mentioned high-voltage load cable positioning member 61 and high-voltage power distribution cable positioning member 71 can both be stud zipties. In this way, during the positioning process of the above-mentioned cables, both the tightness of the stud zipties for fastening the high-voltage load cable 60 and the high-voltage power distribution cable 70 can be adjusted, and the positioning of the high-voltage load cable 60 and the high-voltage power distribution cable 70 can be achieved through methods such as snap connection and threaded connection.

[0050] Alternatively, in other embodiments provided by the present disclosure, the above-mentioned high-voltage load cable positioning member 61 and high-voltage power distribution cable positioning member 71 can both be structures such as clamps and flanges.

[0051] In an exemplary embodiment provided by the present disclosure, the circuit protection component 20 is a loss component, and the circuit protection component 20 can include one or more of a contactor and a fuse 22. It should be noted that the above structure is not limited to the above in the accommodation cavity, and related structures such as copper bars, Hall current sensors, pre-charge resistors, and control circuit boards that cooperate with the circuit protection component 20 can also be provided in the accommodation cavity.

[0052] In addition, there is also a certain empty space in the accommodation cavity, and this empty space can provide an accommodation space for the installation and arrangement of additional components such as contactors or fuses 22 under the requirements of subsequent product function improvement or vehicle overall solution optimization.

[0053] Optionally, as Figure 3 shown, the box body 10 can include a box body 100 and a box cover 101. The box cover 101 detachably covers the open mouth of the box body 100, and the box cover 101 and the box body 100 jointly enclose an accommodation cavity. In this way, when it is necessary to repair or maintain the circuit protection component 20 located in the accommodation cavity, the box cover 101 can be detached from the box body 100. After the repair is completed, the box cover 101 is covered on the box body 100 again, so that the circuit protection component 20 is in a relatively sealed space, reducing or avoiding interference from the outside during driving.

[0054] The present disclosure does not limit the detachable manner between the above-mentioned box body 100 and the box cover 101. For example, the box body 100 and the box cover 101 can be connected by a snap connection method, that is, the box cover 101 is directly snapped onto the box body 100. Or, in another embodiment provided by the present disclosure, the box cover 101 and the box body 100 can also be fixedly connected by a third fastener (such as a fastening bolt).

[0055] The box body 10 of the high-voltage distribution box 1 provided by the present disclosure can be made of aluminum-silicon 10 magnesium-manganese or ADC12 (Al-Si-Cu alloy system), and the overall die-casting process is adopted. The overall thickness requirement is ≥3 mm. The above materials have low density, high strength, and good corrosion resistance, which can further improve the service life of the box body 10.

[0056] The second aspect of the present disclosure provides an electric drive system, including an electric drive assembly and the high-voltage distribution box 1 as described above. The electric drive assembly is preset with insertion holes, and the wiring terminals 40 are inserted into the insertion holes. In this way, during the process of assembling the high-voltage distribution box 1 on the electric drive assembly, the wiring terminals 40 of the high-voltage distribution box 1 can be inserted into the insertion holes provided on the electric drive assembly, and are connected to the output end of the electric drive assembly provided in the insertion hole through the first fastener.

[0057] Moreover, since the connection between the wiring terminal 40 and the output end of the electric drive assembly is located inside the insertion hole, it is possible to avoid the connection between the first fastener and the output end of the electric drive assembly from being invaded and corroded by other structures of the electric drive assembly, impurities in the atmosphere, rainwater and other external factors, and improve the connection stability between the wiring terminal 40 and the output end of the electric drive assembly.

[0058] In addition, precisely because the above-mentioned circuit protection component 20 is arranged in the high-voltage distribution box 1 independent of the electric drive assembly, it is also possible to reduce the space occupied by the circuit protection component 20 in the electric drive assembly. For the implementation manner in which the high-voltage distribution box 1 is arranged on the upper part of the electric drive assembly, it is possible to reduce the size occupation of the electric drive assembly in the length direction and width direction of the vehicle, and increase the layout flexibility of the electric drive assembly. And adopting the above-mentioned solution provided by the present disclosure also has a certain improvement in the overall vehicle production efficiency and the convenience of operation of the production line workers during the process of vehicle production and manufacturing.

[0059] The third aspect of the present disclosure provides a vehicle, including the high-voltage distribution box 1 as described above or the electric drive system as described above. This vehicle has all the beneficial effects of the above-mentioned high-voltage distribution box 1 and the electric drive system assembly, and the present disclosure will not elaborate here.

[0062] Furthermore, any combination can be made between various different embodiments of the present disclosure, as long as it does not violate the idea of the present disclosure, it should also be regarded as the content disclosed by the present disclosure.
