Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0020] Figure 1 This is a schematic diagram of a high-voltage connection assembly provided in an embodiment of this application. Please refer to it. Figure 1 This application provides a high-voltage connection assembly 000, including: a housing 010, a plurality of first connection bars 021 and a plurality of second connection bars 022.

[0021] Multiple first connecting rows 021 and multiple second connecting rows 022 are arranged at intervals in a first direction, and both the first connecting rows 021 and the multiple second connecting rows 022 are connected to the housing 010. The housing 010 has a first side d1 and a second side d2 disposed opposite to each other in a second direction. The first direction and the second direction intersect.

[0022] Each first connecting bar 021 has a first electrical contact b1 and a second electrical contact b2 at both ends, and each second connecting bar 022 has a third electrical contact b3 and a fourth electrical contact b4 at both ends. The first electrical contact b1 and the third electrical contact b3 both protrude from the first side d1 of the outer casing 010. The second electrical contact b2 and the fourth electrical contact b4 both protrude from the second side d2 of the outer casing 010.

[0023] In this configuration, multiple first electrical contacts b1 in multiple first connecting rows 021 and multiple second electrical contacts b2 in multiple second connecting rows 022 are arranged in a first direction. Multiple third electrical contacts b3 in multiple first connecting rows 021 are distributed around a first rotation direction, and multiple fourth electrical contacts b4 in multiple second connecting rows 022 are distributed around a second rotation direction. The first rotation direction is opposite to the second rotation direction.

[0024] For example, in the embodiments of this application, the first direction may be perpendicular to the second direction.

[0025] It should be noted that both the first and second rotation directions mentioned are viewed from the outside in. To more clearly describe the rotation directions here, we will use... Figure 1 Taking the orientation of the high-voltage connection component 000 as an example, for the first rotation direction, "from the outside to the inside" refers to the rotation direction seen from the left to the inside in the first direction. For the second rotation direction, "from the outside to the inside" refers to the rotation direction seen from the right to the inside in the first direction.

[0026] For example, the first rotation direction can be either clockwise or counterclockwise, and the second rotation direction can be either clockwise or counterclockwise, that is, the first rotation direction and the second rotation direction are respectively clockwise and counterclockwise.

[0027] In this embodiment of the application, the following description takes the first rotation direction as clockwise, the second rotation direction as counterclockwise, and the number of the first connecting row 021 and the number of the second connecting row 022 as three.

[0028] The three first connection busbars 021 are used for electrical connection at one end to the busbar 150 of the drive motor 130, and at the other end to the three-phase copper busbar in the motor controller 120. The three first connection busbars 021 can be, for example, the U-phase connection busbar, the V-phase connection busbar, and the W-phase connection busbar.

[0029] The three second connection busbars 022 are used for electrical connection at one end to the busbar 150 of the generator motor 140, and at the other end to the three-phase copper busbar in the motor controller 120. The three second connection busbars 022 can also be, for example, a U-phase connection busbar, a V-phase connection busbar, and a W-phase connection busbar.

[0030] The motor controller 120 is used to control the drive motor 130 and the generator motor 140 respectively.

[0031] The high-voltage connection assembly 000 in this embodiment can be used in a dual-motor hybrid transmission 110. Multiple first connection bars 021 enable electrical connection between the drive motor 130 and the motor controller 120, while multiple second connection bars 022 enable electrical connection between the generator motor 140 and the motor controller 120. Furthermore, all the first and second connection bars 021 and 022 are integrated onto the same housing 010. This integrated high-voltage connection assembly 000 allows for both connection between the drive motor 130 and the motor controller 120, and also between the generator motor 140 and the motor controller 120, effectively reducing the number of connecting parts, simplifying the structure and assembly, and thus saving assembly space for the high-voltage connection assembly 000.

[0032] Figure 2 This is a schematic diagram illustrating an application scenario of a high-voltage connection component provided in an embodiment of this application. Please refer to it. Figure 2 , Figure 2 The structure includes: a high-voltage connection assembly 000, a gearbox 110, and a motor controller 120.

[0033] The gearbox 110 and the motor controller 120 are distributed adjacent to each other in the second direction.

[0034] In the second direction, a portion of the high-voltage connection assembly 000 is located inside the main housing 111 of the gearbox 110, and another portion is located at the motor controller 120.

[0035] The three first electrical contacts b1 in the three first connection bars 021 are respectively connected to the three-phase copper busbars in the motor controller 120 and the drive motor 130, and the three second electrical contacts b2 in the three first connection bars 021 are respectively connected to the busbars 150 in the drive motor 130.

[0036] The three third electrical contacts b3 in the three second connection blocks 022 are respectively connected to the three-phase copper busbars in the motor controller 120 and the generator motor 140, and the three fourth electrical contacts b4 in the three second connection blocks 022 are respectively connected to the busbars 150 in the generator motor 140.

[0037] The three ends of the busbar 150 in the drive motor 130 are distributed along the first rotation direction. Thus, the three third electrical contacts b3 distributed around the first rotation direction can correspond one-to-one with the three ends of the busbar 150 in the drive motor 130. This facilitates direct connection between the third electrical contacts b3 in the first connecting bar 021 and the ends of the busbar 150 in the drive motor 130, eliminating intermediate parts, thereby simplifying the structure and assembly, and saving space.

[0038] The three ends of the busbar 150 in the generator motor 140 are distributed along the second rotation direction. Thus, the three fourth electrical contacts b4 distributed around the second rotation direction can correspond one-to-one with the three ends of the busbar 150 in the generator motor 140. This facilitates direct connection between the fourth electrical contacts b4 in the second connecting busbar 022 and the ends of the busbar 150 in the generator motor 140, eliminating intermediate parts, thereby simplifying the structure and assembly, and saving space.

[0039] In summary, by integrating multiple first and second connecting bars onto the high-voltage connection assembly, it is possible to connect the high-voltage connection assembly to multiple electrical components. This effectively reduces the number of connecting parts, simplifies the structure and assembly, and thus saves assembly space for the high-voltage connection assembly. The multiple third electrical contacts distributed around a first rotation direction in the multiple first connecting bars, and the multiple fourth electrical contacts distributed around a second rotation direction in the multiple second connecting bars, facilitate the correspondence between the connection positions of the multiple third electrical contacts and the busbars of the drive motor, and the connection positions of the multiple fourth electrical contacts and the busbars of the generator motor. This allows for direct electrical connection between the third electrical contacts and the busbars of the drive motor, and between the fourth electrical contacts and the busbars of the generator motor. This eliminates intermediate parts, simplifying the structure and assembly, and saving space. Furthermore, since the electrical contacts are directly connected to the busbars without intermediate components, power consumption is reduced, the reliability of the connection between the high-voltage connection assembly and the motor is improved, and reliable electrical transmission between the motor controller and the motor is achieved.

[0040] In addition, the housing has a first side and a second side disposed opposite to each other in a second direction. The first electrical contact and the third electrical contact are both distributed protruding from the first side of the housing, and the second electrical contact and the fourth electrical contact are both distributed protruding from the second side of the housing. That is, the first electrical contact and the third electrical contact are distributed on both sides of the housing in the second direction, which simplifies the structure of the high-voltage connection assembly and facilitates the design and manufacturing of the high-voltage connection assembly.

[0041] Figure 3 This is a schematic diagram of another high-voltage connection assembly provided in an embodiment of this application. Please refer to it. Figure 3In some possible implementations, the housing 010 includes a mounting portion 013. The mounting portion 013 has a plurality of mounting holes k0 distributed around it.

[0042] In the plurality of first connection rows 021, the distance between each first electrical contact b1 and the fixed mounting part 013 in the second direction is equal, while the distance between different second electrical contacts b2 and the fixed mounting part 013 in the second direction is different.

[0043] In the multiple second connection rows 022, the distance between each third electrical contact b3 and the fixed mounting part 013 in the second direction is equal, while the distance between different fourth electrical contacts b4 and the fixed mounting part 013 in the second direction is different.

[0044] By ensuring that the distances between each first electrical contact b1 and the fixed mounting part 013 in the second direction are equal, and that the distances between each third electrical contact b3 and the fixed mounting part 013 in the second direction are also equal, it is convenient to realize that the multiple first electrical contacts b1 and the multiple second electrical contacts b2 are respectively electrically connected to the three-phase copper busbar in the motor controller 120, and the structure can be simplified.

[0045] By varying the distances between the different second electrical contacts b2 and the fixed mounting portion 013 in the second direction, the positions of the multiple second electrical contacts b2 and the multiple ends of the busbar 150 on the drive motor 130 can be adapted to each other. This allows for direct one-to-one electrical connection between the multiple second electrical contacts b2 and the multiple ends of the busbar 150 on the drive motor 130, thus simplifying the connection structure between the first connecting busbar 021 and the drive motor 130 and saving space.

[0046] By varying the distances between the different fourth electrical contacts b4 and the fixed mounting portion 013 in the second direction, the positions of the multiple fourth electrical contacts b4 and the multiple ends of the busbar 150 on the generator motor 140 can be adapted to each other. This allows for direct one-to-one electrical connection between the multiple fourth electrical contacts b4 and the multiple ends of the busbar 150 on the generator motor 140, thus simplifying the connection structure between the second connecting busbar 022 and the generator motor 140 and saving space.

[0047] In some possible implementations, each mounting hole k0 is fixed with a bushing 014, that is, there is a one-to-one correspondence between the mounting hole k0 and the bushing 014.

[0048] For example, please refer to Figure 4 , Figure 4This is a schematic diagram of another application scenario of the high-voltage connection component provided in the embodiment of this application. The main body shell 111 of the gearbox 110 has a plurality of connection holes that correspond one-to-one with the fixed mounting part 013. The fixed mounting part 013 is placed on the main body shell 111, and the plurality of mounting holes k0 on the fixed mounting part 013 are aligned one-to-one with the plurality of connection holes on the main body shell 111. By passing bolts through the mounting holes k0 and the corresponding connection holes, the fixed mounting part 013 can be connected to the main body shell 111.

[0049] The bushing 014 ensures that the bolts will not damage the fixed mounting part 013 in the housing 010 during bolt installation, and enables the effective installation of the high-pressure connection assembly 000 and the main housing 111.

[0050] Figure 5 This is a schematic diagram of another high-voltage connection assembly provided in the embodiments of this application. Please refer to it. Figure 5 In some possible implementations, in the plurality of first connection rows 021, the distance between the plurality of second electrical contacts b2 and the fixed mounting portion 013 in the second direction gradually decreases in the direction away from the plurality of second connection rows 022, and the plurality of second electrical contacts b2 are spaced apart in the first direction, so as to facilitate the distribution of the plurality of second electrical contacts b2 around the first rotation direction.

[0051] In the plurality of second connecting rows 022, the distance between the plurality of fourth electrical contacts b4 and the fixed mounting portion 013 in the second direction gradually decreases in the direction away from the plurality of first connecting rows 021, and the plurality of fourth electrical contacts b4 are spaced apart in the first direction, so as to facilitate the distribution of the plurality of fourth electrical contacts b4 around the second rotation direction.

[0052] Please refer to Figure 5 In some possible implementations, the distance between the first electrical contact b1 and the fixed mounting part 013 in the second direction is equal to the distance between the third electrical contact b3 and the fixed mounting part 013 in the second direction.

[0053] For example, the first electrical contact portion b1 has a first connection hole k1, and the distance between the plurality of first connection holes k1 in the plurality of first electrical contact portions b1 and the fixed mounting portion 013 is the same in the second direction.

[0054] The second electrical contact part b2 has a second connection hole k2, and the distance between the multiple second connection holes k2 in the multiple first electrical contact parts b1 and the fixed mounting part 013 in the second direction gradually decreases in the direction away from the second connection row 022.

[0055] The third electrical contact part b3 has a third connection hole k3, and the distance between the third connection holes k3 of the plurality of third electrical contact parts b3 and the fixed mounting part 013 in the second direction is the same.

[0056] The fourth electrical contact part b4 has a fourth connection hole k4, and the distance between the multiple fourth connection holes k4 in the multiple fourth electrical contact parts b4 and the fixed mounting part 013 in the second direction gradually decreases in the direction away from the first connection row 021.

[0057] Wherein, the distance between the first connecting hole k1 and the fixed mounting part 013 in the second direction is equal to the distance between the third connecting hole k3 and the fixed mounting part 013 in the second direction.

[0058] Please refer to Figure 3 In one possible implementation, the high-voltage connection assembly 000 further includes a plurality of crimp nuts 030. The plurality of crimp nuts 030 are located on the same side of the plurality of connection rows 020 in a third-order orientation.

[0059] Each rivet nut 030 corresponds to a second connecting hole k2 or a fourth connecting hole k4, and each rivet nut 030 is interference-fitted with the corresponding second connecting hole k2 or fourth connecting hole k4, so that the busbar 150 of the motor and the connecting busbar 020 can be effectively connected by bolts.

[0060] The third direction intersects the first direction and the second direction. For example, the first direction, the second direction, and the third direction are all perpendicular to each other.

[0061] It should be noted that some of the multiple connection rows 020 are the first connection rows 021, and the other part of the connection rows 020 are the second connection rows 022. For example, if there are six connection rows 020, three of the six connection rows 020 are the first connection rows 021, and the other three of the six connection rows 020 are the second connection rows 022.

[0062] In this way, the busbar 150 of the drive motor 130 can be connected to the rivet nuts 030 on the three second connection holes k2 by three bolts, and the busbar 150 of the generator motor 140 can be connected to the rivet nuts 030 on the three fourth connection holes k4 by three bolts.

[0063] For example, the first connecting hole k1 and the third connecting hole k3 are both oblong holes, and the second connecting hole k2 and the fourth connecting hole k4 are both circular holes. The first connecting busbar 021 is electrically connected to the three-phase copper busbar inside the motor controller 120 at the first connecting hole k1 by bolts, and the second connecting busbar 022 is connected to the three-phase copper busbar inside the motor controller 120 at the third connecting hole k3 by bolts. Here, it can be understood that there are two three-phase copper busbars inside the motor controller 120, one corresponding to the drive motor 130 and the other corresponding to the generator motor 140.

[0064] By setting both the first connecting hole k1 and the third connecting hole k3 as oblong holes, the tolerances can be avoided from being concentrated on the copper busbar, thus better preventing the deformation of the connecting busbar 020.

[0065] Figure 6 This is a schematic diagram of another high-voltage connection assembly provided in the embodiments of this application. Please refer to it. Figure 6 In some possible implementations, each first connecting segment 021 includes: a first main body segment 0211, a second main body segment 0212, and a first connecting segment 0213. The two ends of the first connecting segment 0213 are respectively connected to one end of the first main body segment 0211 and one end of the second main body segment 0212. The end of the first main body segment 0211 facing away from the first connecting segment 0213 has a first electrical contact b1, and the end of the second main body segment 0212 facing away from the first connecting segment 0213 has a second electrical contact b2. The first connecting segment 0213 is embedded inside the housing 010. A portion of the first main body segment 0211 is embedded inside the housing 010, and another portion protrudes from a first side d1 of the housing 010. A portion of the second main body segment 0212 is embedded inside the housing 010, and another portion protrudes from a second side d2 of the housing 010.

[0066] The first main body segment 0211, the second main body segment 0212, and the first connecting segment 0213 are integrally processed structures. The first connecting row 021 achieves an indirect bending connection between the first main body segment 0211 and the second main body segment 0212 through the first connecting segment 0213. The bending connection between the first main body segment 0211 and the first connecting segment 0213, as well as the bending connection between the second main body segment 0212 and the first connecting segment 0213, facilitates adaptation to narrow spaces, absorbs vibration, and assists in heat dissipation.

[0067] Each second connecting section 022 includes: a third main body section 0221, a fourth main body section 0222, and a second connecting section 0223. Both ends of the second connecting section 0223 are connected to one end of the third main body section 0221 and one end of the fourth main body section 0222, respectively. The end of the third main body section 0221 facing away from the second connecting section 0223 has a third electrical contact portion b3, and the end of the fourth main body section 0222 facing away from the second connecting section 0223 has a fourth electrical contact portion b4. The second connecting section 0223 is embedded inside the housing 010. A portion of the third main body section 0221 is embedded inside the housing 010, and another portion protrudes from the first side d1 of the housing 010. A portion of the fourth main body section 0222 is embedded inside the housing 010, and another portion protrudes from the second side d2 of the housing 010.

[0068] The third main body section 0221, the fourth main body section 0222, and the second connecting section 0223 are integrally processed structures. The second connecting row 022 achieves an indirect bending connection between the third main body section 0221 and the fourth main body section 0222 through the second connecting section 0223. The bending connection between the third main body section 0221 and the second connecting section 0223, as well as the bending connection between the fourth main body section 0222 and the second connecting section 0223, facilitates adaptation to narrow spaces, absorption of vibration, and auxiliary heat dissipation.

[0069] Please refer to Figure 6 In some possible implementations, each first main body segment 0211 and each third main body segment 0221 extends along the second direction, and the extension length of each first main body segment 0211 is equal to the extension length of each second main body segment 0212.

[0070] The second main body segment 0212 includes a first vertical segment 02121 and a first inclined segment 02122. One end of the first vertical segment 02121 is connected to the first connecting segment 0213, and the other end is connected to one end of the first inclined segment 02122. The end of the first inclined segment 02122 opposite to the first vertical segment 02121 has a second electrical contact portion b2. The first vertical segment 02121 extends along a second direction, and the extension direction of the first inclined segment 02122 intersects the second direction. The housing 010 covers at least a portion of the first vertical segment 02121 and exposes at least a portion of the first inclined segment 02122. In the plurality of first connecting rows 021, the extension length of the plurality of first vertical segments 02121 gradually decreases in a direction away from the plurality of second connecting rows 022.

[0071] The fourth main body segment 0222 includes a second inclined segment 02221 and a second vertical segment 02222. One end of the second inclined segment 02221 is connected to the second connecting segment 0223, and the other end is connected to one end of the second vertical segment 02222. The end of the second vertical segment 02222 facing away from the second inclined segment 02221 has a fourth electrical contact portion b4. The second vertical segment 02222 extends along a second direction, and the extension direction of the second inclined segment 02221 intersects the second direction. The housing 010 covers at least a portion of the second inclined segment 02221 and exposes at least a portion of the second vertical segment 02222. In the plurality of second connecting rows 022, the extension length of the plurality of second vertical segments 02222 gradually decreases in a direction away from the plurality of first connecting rows 021.

[0072] Taking the second main body segment 0212 as an example, it should be noted that the extension direction of the first inclined segment 02122 intersects the second direction. This can be because the extension direction of the first inclined segment 02122 is perpendicular to the second direction, or the angle between the extension direction of the first inclined segment 02122 and the second direction is an obtuse angle (an obtuse angle refers to the angle between the first inclined segment 02122 in the direction toward the fixed mounting part 013 and the second direction). The outer shell 010 covers at least a portion of the first vertical segment 02121. For example, the outer shell 010 covers all of the first vertical segment 02121, or the outer shell 010 includes a portion of the first vertical segment 02121, with the remaining first vertical segment 02121 located outside the outer shell 010. The first inclined segment 02122 can be entirely exposed outside the outer shell 010, or it can be partially located inside the outer shell 010 with another portion exposed outside the outer shell 010.

[0073] The design principles of the fourth main body segment 0222 and the second main body segment 0212 are similar, so the second vertical segment 02222 and the second inclined segment 02221 in the fourth main body segment 0222 will not be explained further.

[0074] Please refer to Figure 6 In some possible implementations, the housing 010 includes: a first socket 011, a fixed mounting portion 013, and a second socket 012. The first socket 011 and the second socket 012 are fixed to opposite sides of the fixed mounting portion 013 in a second direction.

[0075] Each of the first electrical contacts b1 and each of the third electrical contacts b3 protrudes from the first socket 011. Each of the second electrical contacts b2 and each of the fourth electrical contacts b4 protrudes from the second socket 012.

[0076] By using the first socket 011, the fixed mounting part 013, and the second socket 012 in the housing 010, the area that the housing 010 can cover the connecting bar 020 can be increased, thereby better protecting the connecting bar 020 and ensuring the effectiveness and safety of the high-voltage connection assembly 000.

[0077] For example, the housing 010 has a plurality of mounting cavities q spaced apart in a first direction, each mounting cavity q passing through a first socket portion 011, a fixed mounting portion 013, and a second socket portion 012 in the extending direction of the connecting strip 020. The connecting strip 020 is sleeved within the mounting cavity q, and two electrical contacts distributed in the second direction are located outside the mounting cavity q.

[0078] The fixed mounting part 013 can cover the first connecting segment 0213 and the second connecting segment 0223. The first socket part 011 can cover a portion of the first main body segment 0211 near the first connecting segment 0213 and a portion of the third main body segment 0221 near the second connecting segment 0223. The second socket part 012 can cover at least a portion of the first vertical segment 02121 near the first connecting segment 0213 and at least a portion of the second inclined segment 02221 near the second connecting segment 0223.

[0079] Please refer to Figure 6 In some possible implementations, the first socket 011 has a plurality of glue injection grooves c1, which are spaced apart in a first direction and penetrate the first socket 011 in a third direction.

[0080] The high-pressure connection assembly 000 also includes a plurality of seals 040. Each seal 040 corresponds one-to-one with a plurality of injection grooves c1 and one-to-one with a plurality of connecting rows 020. The seals 040 are bonded to the first socket portion 011 within their respective injection grooves c1, and the seals 040 are arranged around the corresponding connecting rows 020 within their respective injection grooves c1 and are bonded to the connecting rows 020.

[0081] By opening a glue injection groove c1 through the first socket 011 in a third direction, and fixing a sealing element 040 in the glue injection groove c1, the sealing element 040, which is bonded to the first socket 011, distributed around the connecting row 020, and bonded to the connecting row 020, can seal the first socket 011 and the connecting row 020 at the glue injection groove c1, prevent oil leakage, and ensure that the equipment can operate normally and effectively.

[0082] The sealing element 040 is fixed at the glue injection groove c1 between the first sleeve 011 and the connecting row 020, without the need for fixing or limiting with other structures, making the sealing structure here simple, reliable, easy to implement and low in cost.

[0083] Figure 7 This is a schematic diagram of a high-voltage connection assembly according to another embodiment of this application. Please refer to it. Figure 7 In some possible implementations, the fixed mounting part 013 has an annular sealing groove c2 on the side facing the second socket part 012.

[0084] The high-voltage connection assembly 000 also includes a sealing ring 050. In the second direction, a portion of the sealing ring 050 is filled and fixed within the annular sealing groove c2, and another portion of the sealing ring 050 protrudes from the fixed mounting portion 013 on the side facing the second socket portion 012.

[0085] Please refer to the following: Figure 8 , Figure 8 This is a schematic diagram of another high-pressure connection assembly provided in another embodiment of this application. The sealing ring 050 has a first sealing surface m1 with a serrated distribution on one side in the second direction, and a second sealing surface m2 with a serrated distribution on the other side in the second direction.

[0086] Bidirectional sealing can be achieved through the serrated first sealing surface m1 and second sealing surface m2, and the sealing performance can be improved by extending the liquid flow path. Furthermore, since the first sealing surface m1 and the second sealing surface m2 are not planar, the sealing ring 050 at the first sealing surface m1 can be elastically deformed, thereby making better sealing contact with the bottom of the corresponding annular sealing groove c2. Similarly, the sealing ring 050 at the second sealing surface m2 can be elastically deformed, thereby making better sealing contact with the corresponding main body shell 111.

[0087] Please refer to Figure 7 In some possible implementations, the fixed mounting part 013 has a positioning pin x on the side facing the second socket part 012. The positioning pin x is used to engage with the hole on the main body shell 111. This facilitates the assembly and positioning of the outer shell 010 and the main body shell 111 in the gearbox 110, and realizes a precise and reliable connection between the high voltage connection assembly 000 and the main body shell 111, the motor, and the motor controller 120.

[0088] For example, there are two locating pins x, which are diagonally distributed on the side of the fixed mounting part 013 facing the second socket part 012.

[0089] Please refer to Figure 6 In some possible implementations, the first socket 011 has a plurality of protrusions t spaced apart in a first direction on the side opposite to the fixed mounting portion 013, and at least one protrusion t is provided between adjacent first connecting rows 021 and between adjacent second connecting rows 022.

[0090] By setting the protrusion t, the creepage distance or path between two adjacent connection bars 020 can be increased, avoiding insulation failure and short circuit between two adjacent connection bars 020, thereby better ensuring the reliability and safety of the high voltage connection assembly 000.

[0091] Please refer to Figure 5 The second socket 012 includes a plurality of first sub-sockets 0121 and a plurality of second sub-sockets 0122 distributed at intervals in a first direction.

[0092] Multiple first sub-socket portions 0121 and multiple second sub-socket portions 0122 are sequentially distributed in the first direction, and the multiple first sub-socket portions 0121 correspond one-to-one with the multiple first connecting rows 021, and the multiple second sub-socket portions 0122 correspond one-to-one with the multiple second connecting rows 022.

[0093] Each first sub-sleeve 0121 has a first surface m3 on the side opposite to the fixed mounting portion 013 in the second direction, and multiple first surfaces m3 are distributed around the first rotation direction. Each second sub-sleeve 0122 has a second surface m4 on the side opposite to the fixed mounting portion 013 in the second direction, and multiple second surfaces m4 are distributed around the second rotation direction.

[0094] Figure 5 To clearly distinguish the multiple second sub-sockets 0122, dashed lines are used to divide them in the first direction to show the boundary between adjacent second sub-sockets 0122.

[0095] by Figure 6 For example, the processing technology of the high-voltage connection component 000 in this application embodiment is described as follows: Stamped connecting strip 020: Six connecting strips 020 are stamped by a continuous stamping die. The cross-section of each connecting strip 020 is, for example, 3*18mm². Based on a typical current carrying capacity of 6A / mm², the current carrying capacity of the connecting strip 020 is 324A, which can realize the effective transmission of current between the motor and the motor controller 120 in the hybrid gearbox 110.

[0096] Assembly of rivet nut 030: After the connecting strip 020 is stamped, the rivet nut 030 is installed on the same side of the connecting strip 020. The rivet nut 030 and the connecting strip 020 are interference fit. The release force of the rivet nut 030 is designed to be >500N, so that the motor busbar 150 and the connecting strip 020 can be effectively connected by bolts.

[0097] Injection molded housing 010: Connecting strip 020 according to... Figure 6The components are arranged in an integrated manner in the injection mold and then integrally injection molded. Simultaneously, a top pin is used in the mold to position the connecting strip 020, ensuring that the connecting strip 020 remains in position during injection molding. This meets the electrical performance requirements of the high-voltage connecting assembly 000, which maintains a minimum electrical clearance of 7.5mm and a minimum creepage distance of 10mm under the rated operating voltage of 400V within the gearbox 110. Two locating pins x are designed on the high-voltage connecting assembly 000 to facilitate precise alignment of the mounting holes k0 with the bolt holes on the main body shell 111 during installation, ensuring effective installation of the high-voltage connecting assembly 000 and the main body shell 111. During the injection molding process of the high-voltage connecting assembly 000, a bushing 014 is placed in each mounting hole k0 and integrally injection molded with the outer shell 010.

[0098] For example, under the rated operating voltage of 800V in the gearbox 110, the minimum electrical clearance between the connecting busbars 020 and 020 is 4.8mm, and the minimum creepage distance is 13.5mm.

[0099] Sealing Design: An annular sealing groove c2 is formed on the lower surface of the fixed mounting part 013, and a sealing ring 050 with anti-detachment raised dots is installed in the annular sealing groove c2. The compression of the sealing ring 050 in the annular sealing groove c2 is, for example, 25%, and the filling rate of the sealing ring 050 in the annular sealing groove c2 is, for example, 93%, achieving a reliable seal between the high-pressure connection component 000 and the main body shell 111. After the outer shell 010 is injection molded, glue is poured into the glue injection groove c1 between the outer shell 010 and the connecting strip 020. The glue is, for example, a silicone glue with good fluidity, oil resistance, and high temperature resistance. It can flow by itself to the gap between the connecting strip 020 and the outer shell 010 during the glue pouring process, thus filling the gap. After curing at room temperature, a sealing element 040 is formed to seal the gap between the connecting strip 020 and the outer shell 010. The sealing element 040, formed by the sealing ring 050 and the potting seal, ensures that the high-pressure connection assembly 000 meets the airtightness requirements of the entire gearbox after being installed on the main body housing 111 of the gearbox 110. An end-face seal is used between the main body housing 111 of the gearbox 110 and the high-pressure connection assembly 000, and potting seal is applied between the copper busbar and the injection-molded housing to achieve a seal between the high-pressure connection assembly 000 and the gearbox 110 housing. This ensures that oil inside the gearbox 110 does not leak into the chamber of the motor controller 120.

[0100] In summary, by integrating multiple first and second connecting bars onto the high-voltage connection assembly, it is possible to connect the high-voltage connection assembly to multiple electrical components. This effectively reduces the number of connecting parts, simplifies the structure and assembly, and thus saves assembly space for the high-voltage connection assembly. The multiple third electrical contacts distributed around a first rotation direction in the multiple first connecting bars, and the multiple fourth electrical contacts distributed around a second rotation direction in the multiple second connecting bars, facilitate the correspondence between the connection positions of the multiple third electrical contacts and the busbars of the drive motor, and the connection positions of the multiple fourth electrical contacts and the busbars of the generator motor. This allows for direct electrical connection between the third electrical contacts and the busbars of the drive motor, and between the fourth electrical contacts and the busbars of the generator motor. This eliminates intermediate parts, simplifying the structure and assembly, and saving space. Furthermore, since the electrical contacts are directly connected to the busbars without intermediate components, power consumption is reduced, the reliability of the connection between the high-voltage connection assembly and the motor is improved, and reliable electrical transmission between the motor controller and the motor is achieved.

[0101] In addition, the housing has a first side and a second side disposed opposite to each other in a second direction. The first electrical contact and the third electrical contact are both distributed protruding from the first side of the housing, and the second electrical contact and the fourth electrical contact are both distributed protruding from the second side of the housing. That is, the first electrical contact and the third electrical contact are distributed on both sides of the housing in the second direction, which simplifies the structure of the high-voltage connection assembly and facilitates the design and manufacturing of the high-voltage connection assembly.

[0102] Another embodiment of this application provides an automobile, including: a motor controller 120, a motor, and a high-voltage connection assembly 000 as described above. The two ends of the high-voltage connection assembly 000 are respectively connected to the motor controller 120 and the motor.

[0103] For example, please refer to Figure 2 The motor includes a drive motor 130 and a generator motor 140. The vehicle also includes a transmission 110 and an engine. The transmission 110 and the motor controller 120 are distributed adjacent to each other in the second direction.

[0104] The three first electrical contacts b1 in the three first connection bars 021 are respectively connected to the three-phase copper busbars in the motor controller 120 and the drive motor 130, and the three second electrical contacts b2 in the three first connection bars 021 are respectively connected to the busbars 150 in the drive motor 130.

[0105] The three third electrical contacts b3 in the three second connection blocks 022 are respectively connected to the three-phase copper busbars in the motor controller 120 and the generator motor 140, and the three fourth electrical contacts b4 in the three second connection blocks 022 are respectively connected to the busbars 150 in the generator motor 140.

[0106] For example, the vehicle in this application is a hybrid vehicle, which can be referred to... Figure 2 Hybrid vehicles, for example, have pure electric mode, series range-extended mode, and energy recovery mode. In pure electric mode, the battery supplies power, and electrical energy is transmitted to the drive motor 130 through the three-phase lines, motor controller 120, and first connector 021, driving the wheels. In series range-extended mode, the engine drives the generator motor 140 to generate electricity, which is transmitted to the motor controller 120 through the busbar 150 and second connector 022, and then to the drive motor 130 through the first connector 021, driving the wheels. In energy recovery mode, during braking / deceleration, the drive motor 130 reverses to generate electricity, which is then transmitted back to the battery through the busbar 150, first connector 021, motor controller 120, and three-phase lines.

[0107] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.

[0108] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
