Description

Technical Field

[0001] This application belongs to the field of high-voltage distribution box technology, specifically relating to a high-strength high-voltage box with rapid assembly function, a power battery, and a vehicle. Background Technology

[0002] With the development of the times, new energy vehicles have increasingly occupied an important position in the market. The battery pack is an indispensable part of new energy vehicles. One of the main components of the battery pack is the battery disconnect unit (BDU). It is the main safety switch of the high-voltage battery pack and the high-voltage power distribution center. Its core functions are safe switching, pre-charge protection, fault isolation, and current monitoring.

[0003] Currently, the PCB board is the main control component of the BDU (Block Utility Unit). Electrical components such as relays and fuses need to be electrically connected to the PCB board through connectors to transmit their status signals to the PCB board and receive control signals from the PCB board, thus controlling various states of the BDU. However, because the connectors are located between the PCB board and the electrical components, the PCB board covers the connectors and busbars. This necessitates the creation of process holes on the PCB board when connecting the connectors and electrical components, inevitably reducing the strength of the PCB board and increasing the number of process steps and costs. Simultaneously, electrical components such as relays and fuses are connected to the load through busbars. However, since busbars are long, plate-shaped components of various shapes, their strength is relatively low, easily leading to increased errors in flatness, parallelism, and relative accuracy between holes during assembly.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0019] With the development of the times, new energy vehicles have increasingly occupied an important position in the market. The battery pack is an indispensable part of new energy vehicles. One of the main components of the battery pack is the battery disconnect unit (BDU). It is the main safety switch of the high-voltage battery pack and the high-voltage power distribution center.

Figure 13This is a schematic diagram of the structure of the first connecting terminal, the second connecting terminal, and the control component in the high-strength high-voltage box with rapid assembly function provided in this application embodiment. The high-strength high-voltage box with rapid assembly function provided in this application embodiment includes a shell 10, a first conductive bus 20, a second conductive bus 30, an electrical component 40, a fixing component 50, a control component 60, and a connector 70. The shell 10 has a cavity 11 and a mounting port 12 communicating with the cavity 11 along a third direction Z; the first conductive bus 20 is integrally formed with the shell 10 and is at least partially exposed in the cavity 11; at least a portion of the second conductive bus 30 passes through the cavity 11 and is connected to the first conductive bus 20; the electrical component 40 is disposed in the cavity 11, and the load terminal of the electrical component 40 is connected to the portion of the first conductive bus 20 exposed in the cavity 11; the electrical component 40 has a first insertion hole 41 on the side of the electrical component 40 near the mounting port 12 along a third direction Z; the fixing component 50 is connected to the second conductive bus 30. The busbar 30 is connected and positioned along the third direction Z on the side of the electrical component 40 near the mounting port 12. The fixing member 50 includes a first plug member 51, which at least partially passes through the first plug hole 41. The control member 60 is disposed on the housing 10 and extends along the plane formed by the first direction X and the third direction Z. The electrical component 40 and the control member 60 are spaced apart along the second direction Y. The connector 70 is spaced apart from the electrical component 40 along the third direction Z and connects the control terminal of the electrical component 40 and the control member 60. This application integrates the first conductive busbar 20 and the housing 10 into a single unit, effectively ensuring the strength of the first conductive busbar 20 and reducing errors in flatness, parallelism, and relative accuracy between holes caused by assembly. By dividing the conductive busbar into two parts, the first conductive busbar 20 and the second conductive busbar 30, and then integrating only the first conductive busbar 20 with the housing 10, the size of the insert and the overall structural complexity can be reduced during the integral molding process. Using smaller, simpler inserts and the housing 10 for integral molding further reduces stress during the integral molding of the conductive busbar and the housing 10, improving molding quality and yield. This application also integrates the control component 60, which extends along the first direction X and the third direction Z, with the electrical component 40 spaced apart along the second direction Y. The connector 70 is then spaced apart from the electrical component 40 along the third direction Z, ensuring that the electrical component 40 is not obstructed in the third direction Z. This eliminates the need for process holes in the control component 60, allowing direct connection between the connector 70 and the electrical component 40, effectively ensuring the strength of the control component 60 and avoiding increased processing steps and costs.

[0022] In some embodiments, the first direction X, the second direction Y, and the third direction Z are orthogonally arranged to form a Cartesian coordinate system. Specifically, the first direction X is the length direction of the BDU, the second direction Y is the width direction of the BDU, and the third direction Z is the height direction of the BDU.

[0023] In some embodiments, the housing 10 of this application is manufactured by injection molding. The housing 10 has a cavity 11 and a mounting port 12 communicating with the cavity 11 along a third direction Z. The cavity 11 and the mounting port 12 are generated during the injection molding of the housing 10. The electrical component 40 is disposed in the cavity 11 through the mounting port 12.

[0024] In some embodiments, electrical component 40 includes relays, fuses, shunts, etc.

[0025] In some embodiments, the control element 60 includes a PCB board, the body of which extends along a plane formed by a first direction X and a third direction Z, and the second direction Y is the thickness direction of the PCB board.

[0026] In some embodiments, the connector 70 includes a nickel strip, one end of which is connected to the control terminal of the electrical component 40, and the other end of which is connected to the control component 60. For example, taking a relay as an example, one end of the nickel strip is connected to the control terminal of the relay by soldering, and the other end of the nickel strip is connected to the control component 60 by soldering.

[0027] In some embodiments, along the third direction Z, the control terminal is disposed on the side of the electrical component 40 near the connector 70 and at the mounting port 12 of the housing 10, so that after the electrical component 40 is disposed in the chamber 11, the control terminal located at the mounting port 12 can be directly connected to the nickel plate. For example, taking a relay as an example, after the relay is inserted into the chamber 11 through the mounting port 12, its control terminal is located at the mounting port 12, and the control terminal of the relay is soldered to the nickel plate.

[0028] In some embodiments, the control member 60 has a first positioning hole 61 and a second positioning hole 62 extending along a second direction Y. The connector 70 includes a first connecting terminal 71 and a second connecting terminal 72. The first connecting terminal 71 passes through the first positioning hole 61 and is connected to the control member 60. Specifically, the first connecting terminal 71 passes through the first positioning hole 61 and is soldered to the control member 60. The second connecting terminal 72 is disposed in the second positioning hole 62 to increase the connection points between the connector 70 and the control member 60, so that when the first connecting terminal 71 is subjected to external force, part of the external force can be distributed to the second connecting terminal 72, thereby improving the torsional and deformation resistance of the first connecting terminal 71 and improving the connection strength between the connector 70 and the control member 60.

[0029] In some embodiments, the second connection terminal 72 includes a limiting boss 73. Along the second direction Y, the limiting boss 73 is disposed on the side of the control member 60 away from the electrical component 40, and the orthographic projection of the limiting boss 73 in the second direction Y at least partially coincides with the control member 60. After the second connection terminal 72 passes through the second positioning hole 62, the limiting boss 73 can abut against the control member 60 along the second direction Y when the second connection terminal 72 moves along the second direction Y, thereby limiting the control member 60 and the second connection terminal 72 in the second direction Y.

[0030] In some embodiments, the connector 70 in this application includes two mutually centrally symmetrical second connecting terminals 72, the center of symmetry being the projection point of the second direction Y, so that when the connector 70 is subjected to a torsional force along the second direction Y, the torsional force can be divided into two parts and uniformly transmitted to the two second connecting terminals 72, the torsional resistance of the two second connecting terminals 72 is uniformized, and the individual second connecting terminal 72 is prevented from being subjected to an uneven and extremely large torsional force and prematurely breaking.

[0031] In some embodiments, along the first direction X, a first connecting terminal 71 is disposed between two second connecting terminals 72 to assist the first connecting terminal 71 in dispersing the torsional force around the third direction Z, thereby improving the torsional resistance of the connector 70 in the third direction Z circumferential direction.

[0032] In some embodiments, along the third direction Z, the first connecting terminal 71 is disposed between two second connecting terminals 72 to assist the first connecting terminal 71 in dispersing the torsional force about the first direction X, thereby improving the torsional resistance of the connector 70 in the first direction X circumferential direction.

[0033] In some embodiments, the materials of the first conductive bus 20 and the second conductive bus 30 include any one or any combination of copper, aluminum, gold, and silver.

[0034] In some embodiments, the portion of the first conductive bus 20 exposed in the chamber 11 has a first connection hole 21, and the second conductive bus 30 passes through the first connection hole 21 to connect to the first conductive bus 20. When connecting the second conductive bus 30 and the first conductive bus 20, the second conductive bus 30 is inserted into the chamber 11 through the mounting port 12, then the second conductive bus 30 is inserted into the first connection hole 21, and finally the connection between the second conductive bus 30 and the first conductive bus 20 is fixed by welding or bolting. Specifically, in this application, welding is used to connect the first conductive bus 20 and the second conductive bus 30 on the side of the first conductive bus 20 furthest from the second conductive bus 30 along the third direction Z.

[0035] In some embodiments, the housing 10 further has a second connection hole 13 communicating with the chamber 11. The first connection hole 21 of the first conductive bus 20 is exposed to the chamber 11 through the second connection hole 13, and the second conductive bus 30 is connected to the first connection hole 21 of the first conductive bus 20 through the second connection hole 13. The second connection hole 13 in this application is generated during the injection molding of the housing 10.

[0036] In some embodiments, the high-strength high-voltage box with rapid assembly function further includes a support member 80, which is disposed in the chamber 11. The support member 80 has a second insertion hole 81 on the side facing the mounting port 12. The support member 80 and the housing 10 are integrally injection molded, and the second insertion hole 81 is formed during injection molding. The fixing member 50 also includes a second insertion member 52, which at least partially passes through the second insertion hole 81. Along the third direction Z, the second insertion member 52 is disposed on the side of the fixing member 50 near the electrical component 40, such that the second insertion member 52 is directly opposite the second insertion hole 81 along the third direction Z. During connection, firstly, the electrical component 40 is inserted into the chamber 11 from the mounting port 12 along the third direction Z. Then, the first plug 51 on the fixing member 50 connected to the second conductive bus 30 is aligned with the first plug hole 41 along the third direction Z, the second plug 52 is aligned with the second plug hole 81, and the second conductive bus 30 is aligned with the first connection hole 21 along the third direction Z. Finally, the fixing member 50 connected to the second conductive bus 30 is pressed along the third direction Z, so that the fixing member 50 simultaneously drives the first plug 51 to be inserted into the first plug hole 41, the second plug 52 to be inserted into the second plug hole 81, and the second conductive bus 30 to be inserted into the first connection hole 21.

[0037] In some embodiments, the fastener 50 includes a plurality of first connectors 51. In this application, two first connectors 51 are provided on the side of the fastener 50 along the third direction Z, closer to the electrical component 40, and the two first connectors 51 are disposed on both sides of the second connector 52, for connecting the two electrical components 40 respectively. The fastener 50 may also integrate multiple first connectors 51, such as 3, 4, 5, or 6, based on actual engineering requirements. It is understood that integrating multiple first connectors 51 onto the fastener 50 can reduce the number of molds, reduce the total number of fasteners 50, reduce the number of mold openings during production, and reduce the number of assembly parts during assembly, thereby reducing production costs and improving production efficiency.

[0038] In some embodiments, a portion of the second conductive bus 30 is integrally injection molded with the fixing member 50 as an insert. In this application, the fixing member 50 is provided with a number of second conductive buses 30 corresponding to the number of first plug-in members 51.

[0039] In some embodiments, the fastener 50 has a third insertion hole 53 on the side away from the mounting port 12 along the third direction Z. The third insertion hole 53 of this application is a groove with an opening along the third direction Z away from the electrical component 40, and the length direction of the groove is parallel to the first direction X. The high-strength high-voltage box with rapid assembly function also includes a cover 90, which is spaced apart from the housing 10 along the third direction Z. The cover 90 is connected to the housing 10 and covers at least part of the mounting port 12 to achieve the encapsulation and fixation of electrical components 40, conductive busbars and fixing members 50. The cover 90 includes a third plug-in member 91, which is disposed along the third direction Z on the side of the cover 90 facing the fixing member 50, and at least part of the third plug-in member 91 passes through the third plug-in hole 53 along the third direction Z. The third plug-in member 91 in this application is a long plate-shaped member, and the length direction of the long plate-shaped member is collinear with the length direction of the groove, so that when the cover 90 is plugged into the housing 10 along the third direction Z, the long plate-shaped third plug-in member 91 is also simultaneously plugged into the groove-shaped third plug-in hole 53 along the third direction Z, so as to further limit the fixing member 50 in the third direction Z.

[0040] In some embodiments, the housing 10 further has a third connection hole 14 communicating with the chamber 11, through which the first conductive bus 20 is exposed in the chamber 11, and the electrical component 40 is connected to the first conductive bus 20 through the third connection hole 14. The third connection hole 14 in this application is generated during the injection molding of the housing 10.

[0041] In some embodiments, the electrical component 40 includes relays, fuses, etc. The load terminal of the electrical component 40 in this application is connected to the first conductive bus 20 through the third connection hole 14. The connection method can be screwing or welding. In this application, the first conductive bus 20 and the load terminal are welded on the side of the first conductive bus 20 away from the electrical component 40.

[0042] Understandably, embodiments of this application provide a high-strength high-voltage box with rapid assembly capability, including a housing 10, a first conductive bus 20, a second conductive bus 30, an electrical component 40, a fixing member 50, a control member 60, and a connector 70. The housing 10 has a chamber 11 and a mounting port 12 communicating with the chamber 11 along a third direction Z; the first conductive bus 20 is integrally formed with the housing 10 and is at least partially exposed in the chamber 11; at least a portion of the second conductive bus 30 passes through the chamber 11 and is connected to the first conductive bus 20; the electrical component 40 is disposed in the chamber 11, and the load terminal of the electrical component 40 is connected to the portion of the first conductive bus 20 exposed in the chamber 11; the electrical component 40 has a first insertion hole 41 on the side along the third direction Z near the mounting port 12; the fixing member 50 is connected to the second conductive bus 30, and... The fixing member 50 is located on the side of the electrical component 40 near the mounting port 12 along the third direction Z. The fixing member 50 includes a first plug member 51, which at least partially passes through the first plug hole 41. The control member 60 is located on the housing 10 and extends along the plane formed by the first direction X and the third direction Z. The control member 60 is connected to the control terminal of the electrical component 40. The electrical component 40 and the control member 60 are spaced apart along the second direction Y. The connecting member 70 is spaced apart from the electrical component 40 along the third direction Z and connects the electrical component 40 and the control member 60. This application integrates the first conductive busbar 20 and the housing 10 into a single unit, effectively ensuring the strength of the first conductive busbar 20 and reducing errors in flatness, parallelism, and relative accuracy between holes caused by assembly. By dividing the conductive busbar into two parts, the first conductive busbar 20 and the second conductive busbar 30, and then integrating only the first conductive busbar 20 with the housing 10, the size of the insert and the overall structural complexity can be reduced during the integral molding process. Using smaller, simpler inserts and the housing 10 for integral molding further reduces stress during the integral molding of the conductive busbar and the housing 10, improving molding quality and yield. This application also integrates the control component 60, which extends along the first direction X and the third direction Z, with the electrical component 40 spaced apart along the second direction Y. The connector 70 is then spaced apart from the electrical component 40 along the third direction Z, ensuring that the electrical component 40 is not obstructed in the third direction Z. This eliminates the need for process holes in the control component 60, allowing direct connection between the connector 70 and the electrical component 40, effectively ensuring the strength of the control component 60 and avoiding increased processing steps and costs.
