[0058] On the one hand, combined with Figure 1-3 As shown, this embodiment provides a motor terminal block 01, which is suitable for high-voltage connection of two three-phase motors 02 in a gearbox housing.

[0059] The motor terminal block 01 includes a terminal body 1 , a first conductive bar group 2 and a second conductive bar group 3 .

[0060] The wiring body 1 is provided with a first power connection terminal 11, a second power connection terminal 12, a third power connection terminal 13 and a fourth power connection terminal 14; the first power connection terminal 11 and the third power connection terminal 13 are respectively used to connect to the three-phase terminals 023 of the two three-phase motors 02; the second power connection terminal 12 and the fourth power connection terminal 14 are respectively used to connect to the high-voltage electrical system 03; the first conductive bar group 2 is electrically connected between the first power connection terminal 11 and the second power connection terminal 12, and the second conductive bar group 3 is electrically connected between the third power connection terminal 13 and the fourth power connection terminal 14.

[0061] The first conductive bar group 2 and the second conductive bar group 3 are detachably disposed on the surface of the wiring body 1 .

[0062] The motor terminal block 01 of this embodiment includes a terminal body 1, a first conductive row group 2 and a second conductive row group 3, wherein the terminal body 1 is provided with four power terminals, the first conductive row group 2 is connected between two of the power terminals to realize the connection between the high-voltage electrical system 03 and a three-phase motor 02, and the second conductive row group 3 is connected between the other two power terminals to realize the connection between the high-voltage electrical system 03 and another three-phase motor 02, thereby solving the problems of difficult motor wiring and poor connection reliability in the integrated design of dual motors and transmissions.

[0063] The two conductive bar groups are detachably connected to the wiring body 1 , and the wiring body 1 is pre-assembled with the conductive bar groups after injection molding, which facilitates the transportation and use of the motor terminal block 01 and the disassembly and maintenance of the conductive bar groups.

[0064] refer to Figure 3 As shown, in some possible implementations, the three-phase motor 02 includes a first three-phase motor 021 and a second three-phase motor 022 . Both three-phase motors 02 are located in a transmission housing and are respectively connected to the transmission.

[0065] The motor terminal block 01 is connected to the inner wall of the gearbox housing. For example, the terminal body 1 is provided with a plurality of assembly through holes, through which screws can be passed to fix the motor terminal block 01 to the inner wall of the gearbox housing.

[0066] In some possible implementations, the first conductive bank group 2 and the conductive bank group are made of metal copper plates.

[0067] refer to Figure 3 As shown, in some other possible implementations, the high-voltage electrical system 03 includes a first high-voltage connector 031 and a second high-voltage connector 032, the second power connection terminal 12 and the fourth power connection terminal 14 on the motor terminal block 01 are respectively connected to one end of the first high-voltage connector 031 and the second high-voltage connector 032, and the other ends of the first high-voltage connector 031 and the second high-voltage connector 032 are respectively connected to the motor controller.

[0068] In one electrical circuit, current flows sequentially through the first high-voltage connector 031, the second power terminal 12, the first conductive bar group 2, and the first power terminal 11, ultimately reaching the first three-phase motor 021. In the other electrical circuit, current flows sequentially through the second high-voltage connector 032, the fourth power terminal 14, the second conductive bar group 3, and the third power terminal 13, ultimately reaching the second three-phase motor 022. Thus, the motor terminal block 01 of this embodiment connects two three-phase motors 02.

[0069] In this disclosure, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, features defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this disclosure, "plurality" means two or more, unless otherwise specifically defined.

[0070] Combine Figure 1 、 4 As shown in Figures 6 and 8, in some embodiments, the first conductive row group 2 includes three first conductive plates 21, each of which is provided with at least one positioning hole 210; the surface of the wiring body 1 has three first fixing grooves 15 arranged in parallel and spaced apart.

[0071] The shape of the first fixing slots 15 corresponds to the shape of the first conductive plates 21 , and the three first conductive plates 21 can be detachably disposed in the three first fixing slots 15 , respectively.

[0072] Each first fixing groove 15 is provided with at least one pair of first clips 151 and at least one positioning column 152; at least one pair of first clips 151 can snap and fix the first conductive plate 21 in the corresponding first fixing groove 15, and at least one positioning column 152 can cooperate with the positioning hole 210 of the first conductive plate 21.

[0073] In this embodiment of the motor terminal block 01, the first conductive row group 2 includes three first conductive plates 21, enabling three-phase electrical conduction. The first conductive plates 21 are accommodated within the first fixing slots 15. The three first fixing slots 15 secure the three first conductive plates 21 at intervals, ensuring stable positioning between the three first conductive plates 21 and preventing them from shifting due to vehicle vibration and causing accidental short circuits.

[0074] Furthermore, the first fixing slot 15 is provided with a first clip 151 and a positioning post 152. The first clip 151 is disposed on both sides of the first fixing slot 15 and can engage and secure the first conductive plate 21 within the first fixing slot 15. The positioning holes 210 of the first conductive plate 21 cooperate with the positioning posts 152 within the first fixing slot 15 to prevent the first conductive plate 21 from moving along the extension direction of the first fixing slot 15, thereby accurately positioning the first conductive plate 21 within the first fixing slot 15.

[0075] For example, the number of the first buckles 151 can be one pair, two pairs, three pairs, etc. The number of each pair of first buckles 151 is two, and the two first buckles 151 appear in pairs according to the position relationship.

[0076] However, it should be understood that the first buckles 151 may also appear individually or in groups of three.

[0077] When the first clips 151 are arranged in pairs, and the number is two or more pairs, the two or more pairs of first clips 151 are spaced apart along the extension direction of the first fixing slot 15 to provide uniform snapping force to the first conductive plate 21 .

[0078] When the first clips 151 are arranged in non-pairs and there are two or more of them, the first clips 151 are alternately arranged on both sides of the first fixing slot 15 along the extension direction of the first fixing slot 15, thereby providing uniform snapping force to the first conductive plate 21.

[0079] Combine Figure 6 As shown, in some embodiments, at least one pair of first clips 151 are symmetrically arranged on both sides of the first fixing groove 15; each first clip 151 in the at least one pair of first clips 151 includes a connecting portion 1511 and a clamping portion 1512, the bottom of the connecting portion 1511 is connected to the wiring body 1, and the top is connected to the clamping portion 1512; at least part of the structure of the clamping portion 1512 protrudes into the first fixing groove 15.

[0080] When the first conductive plate 21 is installed in the first fixing slot 15, the clamping portion 1512 is pressed and opens toward the outside of the first fixing slot 15; after the first conductive plate 21 is installed in the first fixing slot 15, the clamping portion 1512 rebounds under the action of the connecting portion 1511, and the clamping portion 1512 clamps and fixes the first conductive plate 21 in the first fixing slot 15 by buckling the outer side surface of the first conductive plate 21.

[0081] After the first conductive plate 21 is injection-molded, it can be pre-assembled with the wiring body 1 to form the motor terminal block 01, and can be transported and assembled as a whole, thereby improving transportation and assembly efficiency. In addition, it is also convenient to disassemble and replace the first conductive plate 21 during later maintenance.

[0082] Combine Figure 6 As shown, in some embodiments, the first fixing groove 15 includes a first side wall 153 and a second side wall 154 ; the first side wall 153 and the second side wall 154 are arranged in parallel and spaced apart, and together with the surface of the wiring body 1 form the first fixing groove 15 .

[0083] At least one pair of notches 155 are symmetrically formed on the first side wall 153 and the second side wall 154, and at least one pair of first buckles 151 are correspondingly located in the at least one pair of notches 155; the connecting portion 1511 is aligned with the first side wall 153 or the second side wall 154, and the connecting portion 1511 is spaced apart from the first side wall 153 or the second side wall 154 on both sides along the direction of the first fixing groove 15.

[0084] In the motor terminal socket 01 of this embodiment, the first fixing groove 15 includes a first side wall 153 and a second side wall 154. The two side walls can limit the first conductive plate 21 in the first fixing groove 15 to prevent the first conductive plate 21 from moving left and right, ensuring that adjacent first conductive plates 21 maintain a safe distance.

[0085] In order to enable the first buckle 151 to elastically deform when squeezed, the connecting portion 1511 of the first buckle 151 is disconnected from the first side wall 153 or the second side wall 154 , thereby improving the elastic deformation capability of the connecting portion 1511 of the first buckle 151 .

[0086] In some possible implementations, reference Figure 6 As shown, the clamping portion 1512 has a guide inclined surface and a retreat-stopping step surface.

[0087] The guiding slope is located on the inner side of the top of the clamping portion 1512 and can guide when the first conductive plate 21 is pressed down, so that the clamping portion 1512 moves outward and then undergoes elastic deformation, so that the first conductive plate 21 can be smoothly clamped into the first fixing groove 15.

[0088] The stop step surface is located on the inner side of the bottom of the clamping part 1512. After the first conductive plate 21 is clamped in, it can move to the outer side surface of the first conductive plate 21 as the connecting part 1511 recovers. The stop step surface fits with the outer side surface of the first conductive plate 21 to prevent the first conductive plate 21 from falling out of the first fixing groove 15.

[0089] When the first conductive plate 21 needs to be removed from the first fixing slot 15 , the clamping portion 1512 of the first clip 151 is moved outward until the stop step surface moves outside the first conductive plate 21 , thereby allowing the first conductive plate 21 to be removed from the first fixing slot 15 .

[0090] Combine Figure 4 、 6 As shown, in some embodiments, the number of first clips 151 is two pairs, and the number of positioning columns 152 is one; the two pairs of first clips 151 are arranged at intervals along the extension direction of the first fixing groove 15, and the positioning column 152 is located between the two pairs of first clips 151 and in the middle of the first fixing groove 15 along the width direction; the height of at least one positioning column 152 is greater than or equal to the thickness of the first conductive plate 21.

[0091] Combine Figure 8 As shown, in some embodiments, the first conductive plate 21 includes a first bending and crimping section 211 , a first straight extension section 212 , and a second bending and crimping section 213 connected in sequence.

[0092] The first bent and crimped section is located at the first power connection end 11 and can be electrically connected to the three-phase terminal 023 via screws; the first straight extension section 212 is fixed in the first fixing groove 15 by the first clip 151; the second bent and crimped section 213 is located at the second power connection end 12 and can be electrically connected to the high-voltage electrical system 03 via screws.

[0093] Thus, the first conductive plate 21 of this embodiment can realize the connection between the first high-voltage connector 031 and the three-phase terminal 023 of the first three-phase motor 021 through the first bending crimping section 211, the first straight extension section 212 and the second bending crimping section 213, thereby meeting the connection requirements of the first high-voltage connector 031 and the first three-phase motor 021 at different positions.

[0094] Exemplarily, through holes for screws to pass through are respectively provided at both ends of the first conductive plate 21 .

[0095] Combine Figure 1 、 2 As shown in Figures 4 and 7 , in some embodiments, the second conductive row group 3 includes three second conductive plates 31 , and the surface of the wiring body 1 has three second fixing grooves 16 arranged in parallel and spaced apart.

[0096] The shape of the second fixing slots 16 corresponds to the shape of the second conductive plates 31 , and the three second conductive plates 31 can be detachably disposed in the three second fixing slots 16 , respectively.

[0097] The three second fixing grooves 16 are separated in parallel by four third side walls 161 . The four third side walls 161 and the surface of the wiring body 1 form three second fixing grooves 16 .

[0098] A clamping edge 162 is provided at the top of at least one of the two third side walls 161 on both sides of the second fixing groove 16 and protrudes into the second fixing groove 16 . The clamping edge 162 can clamp and fix the second conductive plate 31 in the second fixing groove 16 by pressing the outer side surface of the second conductive plate 31 .

[0099] In this embodiment of the motor terminal block 01, the second conductive row 3 includes three second conductive plates 31, enabling three-phase electrical conduction. The second conductive plates 31 are received within the second fixing slots 16. These slots 16 secure the three second conductive plates 31 at intervals, ensuring stable positioning between the plates 31 and preventing them from shifting due to vehicle vibration and causing accidental short circuits.

[0100] In addition, a clamping edge 162 is provided at the top of the third side wall 161 of the second fixing groove 16 . The clamping edge 162 can clamp and fix the second conductive plate 31 in the second fixing groove 16 .

[0101] Combine Figure 9As shown, in some embodiments, the second conductive plate 31 includes a third bending and crimping section 311 , a second straight extension section 312 , and a fourth bending and crimping section that are sequentially connected.

[0102] The third bent crimping section 311 is located at the third power connection end 13, and can be electrically connected to the three-phase terminal 023 through screws; the second straight extension section 312 is fixed in the second fixing groove 16 by the clamping edge 162; the fourth bent crimping section is located at the fourth power connection end 14, and can be electrically connected to the high-voltage electrical system 03 through screws.

[0103] Thus, the second conductive plate 31 of this embodiment can realize the connection between the second high-voltage connector 032 and the three-phase terminal 023 of the second three-phase motor 022 through the third bending crimping section 311, the second straight extension section 312 and the fourth bending crimping section, thereby meeting the connection requirements of the second high-voltage connector 032 and the second three-phase motor 022 at different positions.

[0104] Exemplarily, through holes for screws to pass through are respectively provided at both ends of the second conductive plate 31 .

[0105] Combine Figure 4 、 5 As shown, in some embodiments, the wiring body 1 includes a first structural portion 17 , a second structural portion 18 and a third structural portion 19 that are integrally injected.

[0106] The second structure portion 18 and the third structure portion 19 are respectively connected to the first structure portion 17 ; the first structure portion 17 and the second structure portion 18 are respectively close to the three-phase terminals 023 of the two three-phase motors 02 .

[0107] The first power connection terminal 11 is located on the first end surface 171 of the first structure portion 17 facing one of the three-phase motors 02 , and the second power connection terminal 12 is located on the second end surface 191 of the third structure portion 19 facing the high-voltage electrical system 03 . The first conductive bar group 2 is detachably disposed on the surface of the third structure portion 19 .

[0108] The third power terminal 13 is located on a third end surface 181 of the second structure portion 18 facing another three-phase motor 02 . The fourth power terminal 14 is located on a fourth end surface 182 of the second structure portion 18 facing the high-voltage electrical system 03 . The second conductive bar group 3 is detachably disposed on the surface of the second structure portion 18 .

[0109] The wiring body 1 of this embodiment comprises a first structural portion 17, a second structural portion 18, and a third structural portion 19, all integrally injection-molded, resulting in high overall strength. The first structural portion 17 and the second structural portion 18 are positioned adjacent to the three-phase terminals 023 of the two three-phase motors 02, reducing the distance between the terminals 023 and improving the system's compactness and reliability.

[0110] The first conductive bar group 2 is detachably mounted on the surface of the third structural portion 19. The third structural portion 19 provides fixation and support for the first conductive bar group 2, thereby improving the reliability and stability of the first conductive bar group 2. The second conductive bar group 3 is detachably mounted on the surface of the second structural portion 18. The second structural portion 18 provides fixation and support for the second conductive bar group 3, thereby improving the reliability and stability of the second conductive bar group 3.

[0111] In some possible implementations, metal nuts are embedded in the wiring body 1 at positions corresponding to the first power terminal 11, the second power terminal 12, the third power terminal 13, and the fourth power terminal 14. The metal nuts are integrally injection-molded into the wiring body 1, so that when the first conductive plate 21, the second conductive plate 31, or the three-phase terminal 023 is crimped using a screw, the metal screw and the nut engage to achieve crimping of the first conductive plate 21, the second conductive plate 31, or the three-phase terminal 023.

[0112] In some other possible implementations, the first fixing groove 15 is located on one side of the third structural portion 19, and a mesh reinforcement rib 192 is provided on the other side of the third structural portion 19. The mesh reinforcement rib 192 can increase the strength of the third structural portion 19 and improve the structural strength of the wiring body 1. Figure 4 、 5 In the embodiment, the three first fixing grooves 15 are located on the upper side of the third structural portion 19 , and the mesh reinforcement ribs 192 are located on the lower side of the third structural portion 19 .
