[0054] The following describes an embodiment of the present disclosure in detail. The embodiment described with reference to the accompanying drawings is exemplary. Referring to Figures 1 to 11 , a connecting device 2 according to an embodiment of the present disclosure is described. The connecting device 2 includes a first connecting socket 10 and a second connecting socket 20 .

[0055] Specifically, as shown in Figures 1-6, the first connection base 10 extends along a first direction A. A plurality of first input terminals 111 are provided on both sides of the first connection base 10 along a second direction B. The first direction A intersects the second direction B. The second connection base 20 is electrically connected to the first connection base 10, extends along the second direction B, and is provided with a plurality of second output terminals 21.

[0056] In this embodiment, the first connecting base 10 extends along the first direction A, the second connecting base 20 is connected to one end of the first connecting base 10 along the first direction A, the second connecting base 20 extends along the second direction B, and the first connecting base 10 and the second connecting base 20 are connected in a T-shape. The first connecting base 10 is provided with a plurality of first access terminals 111 on both sides along the second direction B, and the plurality of first access terminals 111 on each side along the second direction B are spaced apart along the first direction A. The plurality of second outlet terminals 21 can be provided on a side of the second connecting base 20 away from the first connecting base 10 for electrical connection with the electronic control device 4. When the first connecting base 10 is connected to two motors at the same time, it can be provided between the two motors for electrical connection with the two motors at the same time. That is, when the connecting device 2 is provided between the two motors, the two motors are electrically connected to the first access terminals 111 on both sides of the first connecting base 10 along the first direction A, respectively.

[0057] The intersection of the first direction A and the second direction B can be understood as the first direction A being perpendicular to the second direction B, but is not limited to being perpendicular. For example, the first direction A and the second direction B form an angle of 80 degrees or 70 degrees.

[0058] According to the connecting device 2 of the embodiment of the present disclosure, by making the first connecting seat 10 and the second connecting seat 20 connected to each other extend along the first direction A and along the second direction B respectively, it is convenient to set multiple first access ends 111 on the first connecting seat 10 to connect with different motors without the need for multiple intermediate steps. The types of materials and the assembly errors between the first connecting seat 10 and the second connecting seat 20 and components such as the motor can be reduced, thereby reducing the cost and reliability of the connecting device 2, making the structure of the connecting device 2 more compact, reducing the volume of the connecting device 2, and effectively reducing the difficulty of the assembly process, which is conducive to the integrated and miniaturized design of the connecting device 2.

[0059] In some embodiments, as shown in FIG2 , the first connector 10 includes a first connector 11 and a second connector 12. The first connector 11 extends along a first direction A, with a plurality of first inlet terminals 111 disposed on either side of the first connector 11 along a second direction B. The second connector 12 is connected to the first connector 11 and extends along a second direction B. The second connector 20 is electrically connected to the second connector 12, with the first direction A and the second direction B being perpendicular. It is understood that the first and second connectors 11 and 12 form a T-shaped connection, extending in the first and second directions A and B, respectively. The plurality of first inlet terminals 111 are disposed on either side of the first connector 11 along the second direction B, spaced apart on the first connector 11 along the first direction A. The two motors are electrically connected to the first connector 11 via the first inlet terminals 111, and the second connector 12 is electrically connected to the second connector 20 via the second outlet terminals 21. Both the first inlet terminals 111 and the second outlet terminals 21 are copper busbars.

[0060] Thus, the arrangement of the first connecting portion 11 and the second connecting portion 12 facilitates the arrangement of the first input terminal 111 and the connection between the first connecting base 10 and the second connecting base 20, fully utilizing the space on the connecting device 2 to avoid interference between the multiple first input terminals 111 and the multiple second output terminals 21. The second connecting portion 12 extending along the second direction B is opposite to the second connecting base 20, facilitating connection with the second connecting base 20.

[0061] In some embodiments, as shown in FIG3 , the plurality of first access terminals 111 include a plurality of first sub-access terminals 1111 and a plurality of second sub-access terminals 1112. The plurality of first sub-access terminals 1111 are spaced apart from one another along the first direction A on one side of the first connection portion 11 along the second direction B. The plurality of second sub-access terminals 1112 are spaced apart from one another along the first direction A on the other side of the first connection portion 11 along the second direction B. In this embodiment, taking three first sub-access terminals 1111 and three second sub-access terminals 1112 as an example, the plurality of first sub-access terminals 1111 are spaced apart from one another along the first direction A, and the plurality of second sub-access terminals 1112 are spaced apart from one another along the first direction A. The plurality of first sub-access terminals 1111 are adapted to electrically connect to a motor located on the one side, and the plurality of second sub-access terminals 1112 are adapted to electrically connect to a motor located on the other side.

[0062] Therefore, the arrangement of the first sub-access terminal 1111 and the second sub-access terminal 1112 facilitates electrical connection of the two motors to the first sub-access terminal 1111 and the second sub-access terminal 1112 on both sides along the second direction B, thereby increasing the utilization of the space on both sides of the first connection portion 11.

[0063] In some embodiments, as shown in Figures 2 and 3, the plurality of first sub-access terminals 1111 and the plurality of second sub-access terminals 1112 are symmetrically arranged about the first connecting portion 11. That is, the plurality of first sub-access terminals 1111 and the plurality of second sub-access terminals 1112 disposed on either side of the first connecting portion 11 along the second direction B are identical in structure, ensuring that the dimensions of the two motors electrically connected to the first connecting portion 11 along the second direction B are identical. This allows for consistent lead wire structures for the two motors, reduces cost and assembly difficulty, and improves the efficiency of connecting the first sub-access terminals 1111 and the second sub-access terminals 1112 to the motors.

[0064] In some embodiments, as shown in Figures 2 and 6, the second connection portion 12 is provided with a plurality of first outlet terminals 121; the second connection base 20 is provided with a plurality of second inlet terminals 22, and the plurality of second inlet terminals 22 are electrically connected to the plurality of first outlet terminals 121 to achieve electrical connection between the second connection base 20 and the first connection base 10. The plurality of first outlet terminals 121 are spaced apart along the second direction B, and the plurality of first outlet terminals 121 are opposite to and electrically connected to the plurality of second inlet terminals 22, facilitating connection between the first connection base 10 and the second connection base 20 via the first outlet terminals 121 and the second inlet terminals 22. For example, the plurality of first outlet terminals 121 include a plurality of first sub-outlets and a plurality of second sub-outlets, wherein the plurality of first sub-outlets are respectively connected to the plurality of first inlet terminals 1111 and are all located on one side of the second direction B. The plurality of second sub-outlets are respectively connected to the plurality of second inlet terminals 1112 and are located on the other side of the second direction B. The plurality of first outlet terminals 121 correspond to the plurality of first input terminals 111, and the connecting device 2 for connecting the two motors is placed between the two motors, so that the two motors are connected to the first connecting seat 10 on both sides of the second direction B, thereby increasing the utilization rate of the space of the connecting device 2 and making better use of the gap between the two motors.

[0065] In some embodiments, as shown in Figures 2 and 4, the plurality of first outlet terminals 121 are located on a side of the plurality of first inlet terminals 111 adjacent to the second connection base 20. That is, the first outlet terminals 121 are located at an end of the first connection base 10 adjacent to the second connection base 20, and the second inlet terminals 22 are located at an end of the second connection base 20 adjacent to the first connection base 10. The plurality of first outlet terminals 121 and the plurality of second inlet terminals 22 are opposite to each other along the first direction A. Thus, the plurality of first outlet terminals 121 are located on a side adjacent to the second connection base 20, facilitating connection between the first outlet terminals 121 and the second inlet terminals 22, reducing the size of the connecting device 2 in the second direction B, and reducing the space occupied on both sides of the first connection base 10 along the second direction B.

[0066] In some embodiments, as shown in FIG2 , multiple first outlet terminals 121 are spaced apart along the second direction B, and the multiple first outlet terminals 121 correspond to the multiple first access terminals 111, respectively. If the number of first access terminals 111 and first outlet terminals 121 is the same, they correspond one to one when connected. Multiple second access terminals 22 are spaced apart along the second direction B, and the multiple second access terminals 22 are connected to the multiple first outlet terminals 121, respectively. This facilitates the connection between the first connection base 10 and the second connection base 20 at one end of the first connection base 10 along the first direction A, avoids the need for intermediate connections between the first connection base 10 and the second connection base 20, reduces costs, and avoids taking up too much space.

[0067] In some embodiments, as shown in Figures 3, 4 and 5, first connection holes 1211 are respectively formed on the multiple first connection ends 121, and second connection holes 221 are respectively formed on the multiple second connection ends 22. The multiple first connection holes 1211 are respectively opposite to the multiple second connection holes 221 and are connected by fasteners 16 to achieve mechanical and electrical connection between the second connection base 20 and the first connection base 10. Specifically, a first connection hole 1211 is formed on the first connection end 121 and passes through the first connection end 121 in the third direction C, and a second connection hole 221 is formed on the second access end 22 and passes through the second access end 22 along the third direction C. The first connection hole 1211 and the second connection hole 221 are opposite to each other in the third direction C. The fastener 16 passes through the first connection hole 1211 and the second connection hole 221 to fix the first connection end 121 and the second access end 22 together. Since the first connection end 121 and the second access end 22 are conductive copper bars, the first connection end 121 and the second access end 22 are mechanically connected and electrically connected at the same time, so as to ensure that the components connected to the first connection seat 10 and the second connection seat 20 can achieve electrical communication.

[0068] Therefore, the setting of the first connecting hole 1211 and the second connecting hole 221 facilitates the fixed connection and electrical connection between the first connecting seat 10 and the second connecting seat 20, and the setting of the connecting holes reduces the process difficulty of the connection between the first connecting seat 10 and the second connecting seat 20, and improves the efficiency of the connection between the first connecting seat 10 and the second connecting seat 20.

[0069] In some embodiments, as shown in FIG2 , the plurality of second outlet terminals 21 are located on a side of the plurality of second inlet terminals 22 away from the first connection base 10. That is, after the first connection base 10 and the second connection base 20 are fixedly connected, the second outlet terminals 21 provided on the second connection base 20 are located on a side of the second connection base 20 away from the first connection base 10, and the first inlet terminals 111 provided on the first connection base 10 are respectively located on both sides of the first connection base 10 along the second direction B. Thus, the positioning of the second outlet terminals 21 facilitates electrical connection and installation between the second outlet terminals 21 and external devices such as electronic controls, while also reducing interference with components installed on the first inlet terminals 111, thereby making the layout of the connection device 2 more reasonable and facilitating the arrangement of components connected to the first connection base 10 and the second connection base 20. This makes the structure of the connection device 2 more compact, facilitating the miniaturization and integrated design of the connection device 2.

[0070] In some embodiments, as shown in Figures 2-6 , at least one of the first connecting portion 11 and the second connecting portion 12 is provided with a plurality of mounting locations 133. For example, some of the plurality of mounting locations 133 are provided on the first connecting portion 11, while others are provided on the second connecting portion 12. When the connecting device 2 needs to be fixed, such as when the connecting device 2 is installed within the housing 3 of the drive assembly 1 having two motors, the connecting device 2 can be fixedly connected to the housing 3 via the mounting locations 133 provided on the first connecting portion 11 and the second connecting portion 12. Thus, the provision of the mounting locations 133 facilitates the installation of the first connecting portion 11 and the second connecting portion 12.

[0071] 1 and 2 , the plurality of mounting positions 133 include a plurality of first mounting positions 13 and a plurality of second mounting positions 14. The plurality of first mounting positions 13 are provided on the first connecting portion 11, and the plurality of second mounting positions 14 are provided on the second connecting portion 12. The plurality of second mounting positions 14 are respectively located on both sides of the plurality of first connecting terminals 121. Thus, the provision of the second mounting positions 14 facilitates the installation of the second connecting portion 12. Furthermore, since the second mounting positions 14 are located at both ends of the second connecting portion 12 along the second direction B, that is, on both sides of the plurality of first connecting terminals 121 along the second direction B, the installation of the second connecting portion 12 can be facilitated to balance the forces on the second connecting portion 12, thereby increasing the stability of the installation of the second connecting portion 12. Furthermore, the difficulty of the process can be reduced, the interference of the mounting positions 133 with the setting position of the first connecting terminals 121 can be facilitated, and the safety of the installation of the mounting positions 133 can be increased.

[0072] In some embodiments, as shown in FIG2 , the plurality of first mounting positions 13 include a plurality of first sub-mounting positions 131 and a plurality of second sub-mounting positions 132 . The plurality of first sub-mounting positions 131 are disposed at an end of the first connecting portion 11 away from the second connecting portion 12 , and the plurality of first sub-mounting positions 131 are arranged along the second direction B. Along the first direction A, the plurality of second sub-mounting positions 132 are located between the plurality of first sub-mounting positions 131 and the plurality of second mounting positions 14 .

[0073] In this embodiment, there are two first sub-mounting positions 131 and two second sub-mounting positions 132. The two first sub-mounting positions 131 are located at one end of the first connecting portion 11 away from the second connecting portion 12 and are spaced apart and adjacent to each other along the second direction B. The two second sub-mounting positions 132 are respectively located on both sides of the first connecting portion 11 along the second direction B. That is, one of the second sub-mounting positions 132 is located between the plurality of first sub-access terminals 1111, or between the first sub-access terminal 1111 and the first sub-mounting position 131, or between the first sub-access terminal 1111 and the second mounting position 14. The other second sub-mounting position 132 is located between the plurality of second sub-access terminals 1112, or between the second sub-access terminal 1112 and the first sub-mounting position 131, or between the second sub-access terminal 1112 and the second mounting position 14.

[0074] In some embodiments, as shown in FIG2 , a plurality of guide grooves 122 are formed on the second connection portion 12, and a plurality of first connection terminals 121 are respectively disposed in the plurality of guide grooves 122. The plurality of second connection terminals 22 are respectively guided and engaged with the plurality of guide grooves 122 and are respectively electrically connected to the plurality of first connection terminals 121. The guide grooves 122 are open along the first direction A toward one end of the second connection seat 20. The second connection terminals 22 provided on the second connection seat 20 can be guided and engaged with the guide grooves 122, that is, the second connection terminals 22 can be inserted into the guide grooves 122 along the first direction A to engage with the guide grooves 122. After engagement, the second connection terminals 22 and the first connection terminals 121 are electrically connected via the fasteners 16. Thus, the guide grooves 122 can limit the second connection terminals 22 along the second direction B, thereby preventing the second connection seat 20 from deviating in the second direction B when the first connection seat 10 and the second connection seat 20 are connected, thereby improving installation efficiency.

[0075] 3 and 6 , at least one of the first connection base 10 and the second connection base 20 is provided with a plurality of positioning pins 134. The provision of the plurality of positioning pins 134 facilitates the pre-installation positioning of the first connection base 10 and the second connection base 20, improving the efficiency and accuracy of installation.

[0076] In some embodiments, as shown in Figures 3 and 6, the plurality of locating pins 134 include a plurality of first locating pins 15 and a plurality of second locating pins 23. The plurality of first locating pins 15 are disposed at both ends of the first connecting base 10 along the first direction A. The plurality of first locating pins 15 are located on one side of the first connecting base 10 along the third direction C. The third direction C, the first direction A, and the second direction B are orthogonal. In other words, the first locating pins 15 can be positioned along the third direction C toward the side of the connecting device 2, depending on the location of the connecting device 2 within the drive assembly 1 and the specific surface of the housing 3 of the drive assembly 1 to which it is connected, and are not specifically limited herein. The first locating pins 15 can provide support for the first connecting base 10 in the first direction A.

[0077] 6 , multiple second locating pins 23 are provided at both ends of the second connecting base 20 along the second direction B, and the multiple second locating pins 23 are located on the side of the second connecting base 20 facing the first connecting base 10. That is, the second locating pins 23 are provided on the second connecting base 20 along the second direction B and extend along the first direction A toward the first connecting base 10. When the second connecting base 20 is installed, the second locating pins 23 can support and limit the connection device 2 in the first direction A. Thus, the provision of the multiple first locating pins 15 and the multiple second locating pins 23 facilitates the installation and positioning of the first connecting base 10 and the second connecting base 20, thereby simplifying the installation of the first connecting base 10 and the second connecting base 20 and improving the installation accuracy of the first connecting base 10 and the second connecting base 20.

[0078] In some embodiments, referring to FIG3 , one of the plurality of first positioning pins 15 is disposed at an end of the first connecting portion 11 away from the second connecting portion 12, and another of the plurality of first positioning pins 15 is disposed at an end of the second connecting portion 12 along the second direction B. In this embodiment, there are two first positioning pins 15: one disposed at the end of the first connecting portion 11 away from the second connecting portion 12, and the other disposed on one side of the second connecting portion 12 along the second direction B, thereby positioning the first connecting base 10 in multiple directions. Optionally, first positioning pins 15 are disposed on both sides of the second connecting portion 12 along the second direction B.

[0079] In some embodiments, the plurality of first locating pins 15 and the first connecting base 10 are integrally formed as an injection-molded part, and the plurality of second locating pins 23 and the second connecting base 20 are integrally formed as an injection-molded part. By using an integral injection molding process to form the first locating pins 15 and the second locating pins 23 on the first connecting base 10 and the second connecting base 20, respectively, the manufacturing process of the first connecting base 10 and the second connecting base 20 can be simplified, the structural strength of the first locating pins 15 and the second locating pins 23 can be improved, the stability of the installation of the first connecting base 10 and the second connecting base 20 can be increased, and the production cycle can be improved.

[0080] In some embodiments, the locating pin 134 is a tapered locating pin. This is primarily because the tapered locating pin provides precise guidance, ensuring precise alignment of the connecting device 2 during installation. It also provides extremely stable positioning and support, helping to improve installation stability. It also facilitates assembly and disassembly of the connecting device 2, saving time and improving efficiency. Furthermore, the pin can accommodate various hole diameters, reducing the requirements for the corresponding hole.

[0081] In some embodiments, as shown in FIG1 , the middle portion of the second connection base 20 is connected to one end of the first connection base 10 along the first direction A. In this embodiment, the second connection base 20 is opposite to the second connection portion 12 and is fixedly and electrically connected thereto. The first connection portion 11 is provided on a side of the second connection portion 12 away from the second connection base 20. One end of the first connection portion 11 adjacent to the second connection base 20 is connected to the middle portion of the second connection portion 12 along the second direction B. The first connection portion 11 and the second connection portion 12 are connected in a T-shape. The second connection base 20 is opposite to and connected to the second connection portion 12, so that the first connection base 10 and the second connection base 20 are connected as a whole in a T-shape. Thus, one end of the first connection base 10 along the first direction A is connected to the middle portion of the second connection base 20, which facilitates the use of the space between the two motors by the connection device 2, facilitates the flat design of the connection device 2, and facilitates the connection of the motor and the electronic control to the connection device 2 on the same side of the connection device 2.

[0082] The drive assembly 1 according to the embodiment of the second aspect of the present disclosure, as shown in Figure 8, includes a housing 3, an electronic control device 4, a first motor 5, a second motor 6 and a connecting device 2, the electronic control device 4 is arranged in the housing 3; the first motor 5 and the second motor 6 are arranged in the housing 3, the connecting device 2 is the connecting device 2 of any of the above embodiments, the first motor 5 and the second motor 6 are electrically connected to multiple first input ends 111 of the first connecting seat 10 of the connecting device 2, and the electronic control device 4 is electrically connected to multiple second output ends 21 of the second connecting seat 20 of the connecting device 2.

[0083] As shown in Figures 7 and 10, the electronic control device 4, multiple motors (e.g., the first motor 5 and the second motor 6), and the connecting device 2 are all disposed within the housing 3. The electronic control device 4, the first motor 5, and the second motor 6 are all electrically connected to the connecting device 2.

The electronic control device 4, the first motor 5, and the second motor 6 are located on the same side of the connecting device 2.

[0084] According to the drive assembly 1 of the embodiment of the present disclosure, by disposing the connecting device 2 and the motor and electronic control device 4 connected to the connecting device 2 within the housing 3, the volume of the drive assembly 1 can be reduced, which is beneficial to the integrated and miniaturized design of the drive assembly 1 and improves the utilization rate of the internal space of the housing 3. At the same time, because the first motor 5, the second motor 6, and the electronic control device 4 are all located on the same side of the connecting device 2 along the third direction C, it is convenient to increase the utilization rate of the space between the first motor 5 and the second motor 6, as well as the space between the first motor 5, the second motor 6, and the electronic control device 4. This can effectively reduce the space occupied by the drive assembly 1 along the second direction B, reduce the overall size of the drive assembly 1, and make the overall vehicle layout more feasible.

[0085] In some embodiments, as shown in Figure 7, the first motor 5 and the second motor 6 are located on either side of the first connecting base 10, and are electrically connected to the first access terminals 111 on the corresponding side. The first motor 5 and the second motor 6 are adapted to be located on either side of the first connecting base 10 along the second direction B, and are electrically connected to the first access terminals 111 on the corresponding side. When the drive assembly 1 is positioned within a vehicle, the utilization of the vehicle interior space in the third direction C can be increased, facilitating a flat design of the connecting base and increasing the utilization of the space within the first connecting base 10 in the second direction B.

[0086] 7 and 11 , the first motor 5 is provided with a first terminal 501, and the second motor 6 is provided with a second terminal 601. There are multiple first and second terminals 501, 601. The multiple first terminals 501 are electrically connected to the first sub-input terminal 1111, and the multiple second terminals 601 are electrically connected to the second sub-input terminal 1112. When the second connection base 20 is connected to the motor device, the three second output terminals 21 on the second connection base 20 near the first motor 5 are electrically connected to the three-phase copper busbar terminals on the electronic control device 4 that control the first motor 5. The three second output terminals 21 on the second connection base 20 near the second motor 6 are electrically connected to the three-phase copper busbar terminals on the electronic control device 4 that control the second motor 6.

[0087] In some embodiments, as shown in FIG8 , the housing 3 has a motor cavity 302 and an electric control cavity 301, the first motor 5 and the second motor 6 are disposed in the motor cavity 302, the electric control device 4 is disposed in the electric control cavity 301, the first connecting seat 10 is disposed in the motor cavity 302, and the second connecting seat 20 is disposed in the electric control cavity 301. For example, the housing 3 has a middle plate, with the motor cavity 302 and the electric control cavity 301 formed on both sides of the middle plate, and at least one middle hole formed in the middle plate, the motor cavity 302 and the electric control cavity 301 being connected through the middle hole. The second connecting seat 20 is disposed in the electric control cavity 301 and abuts against the middle plate, the first connecting seat 10 is disposed in the motor cavity 302 and abuts against the middle plate, the electric control device 4 is disposed in the electric control cavity 301 and is located on the side of the second connecting seat 20 away from the middle plate, the first motor 5 and the second motor 6 are disposed in the motor cavity 302 and are respectively disposed on both sides of the first connecting seat 10 and are respectively connected to the first connecting portion 11. The first motor 5 , the second motor 6 , the electronic control device 4 and the connecting device 2 are respectively connected to the inner wall of the box body 3 .

[0088] Therefore, the electronic control device 4 and the motors 5 and 6 are respectively arranged in different chambers, so that the oil and other substances generated by the motors during operation will not affect the electronic control device 4, so that the electronic control device 4 can efficiently adjust the first motor 5 and the second motor 6, thereby improving the stability and reliability of the adjustment.

[0089] In some embodiments, as shown in Figures 8 and 9, the drive assembly 1 further includes a seal 17, which is disposed between the second connecting seat 20 and the housing 3 to seal the motor cavity 302 and the electric control cavity 301. The seal 17 is disposed on the side of the second connecting seat 20 facing the first connecting seat 10. When the second connecting seat 20 is installed in the electric control cavity 301, the seal 17 is disposed between the second connecting seat 20 and the middle plate. The second connecting seat 20 can compress the seal 17 to increase the seal between the motor cavity 302 and the electric control cavity 301, thereby preventing the paint in the motor cavity 302 from entering the electric control cavity 301 and increasing the safety of the drive assembly 1. The sealing structure is simple and highly reliable, which can also reduce costs and process difficulty.
