[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0039] According to the first aspect of this application, please refer to Figure 1 and Figure 2 The integrated terminal block provided in this disclosure includes a terminal block body 2, a left motor lead wire 8 and a right motor lead wire 9, wherein the left motor lead wire 8 and the right motor lead wire 9 are connected to the same terminal block body 2.

[0040] Among them, motor systems suitable for dual motors.

[0041] Understandably, the dual-motor system has a left motor lead 8 and a right motor lead 9. The two separate terminal blocks on the dual-motor side are eliminated, and an integrated terminal block is used to connect to the left motor lead 8 and the right motor lead 9.

[0042] In this embodiment, the integrated terminal block includes a terminal block body 2, a left motor lead 8, and a right motor lead 9. The left motor lead 8 and the right motor lead 9 are connected to the same terminal block body 2. Only one terminal block body 2 is needed to connect to both the left motor lead 8 and the right motor lead 9 simultaneously, eliminating the need for at least one terminal block body 2. This avoids the large space occupation caused by setting multiple terminal block bodies 2, saves space, and is conducive to achieving lightweight motor system. It also alleviates the technical problem of existing technologies that require at least two terminal blocks, resulting in large space occupation and hindering lightweight implementation.

[0043] In one embodiment, please refer to Figure 3 It may also include at least two motor leads, including but not limited to the left motor lead 8 and the right motor lead 9.

[0044] In one embodiment, please refer to Figure 1 An electrical channel is formed inside the terminal block body 2, and the left motor lead wire 8 and the right motor lead wire 9 are partially located in the electrical channel.

[0045] The electrical channel is used for electrical connection with the left motor lead 8 and the right motor lead 9.

[0046] It is understandable that by forming an electrical channel within the terminal block body 2, it is possible to better connect electrically to the left motor lead 8 and the right motor lead 9.

[0047] In one embodiment, please refer to Figure 5 The terminal block body 2 is provided with three-phase terminals and a neutral terminal. The three-phase terminals are electrically connected to the three-phase lines, and the neutral terminal is electrically connected to the neutral line.

[0048] Among them, the three-phase terminals are used to connect the three-phase power lines of the motor. The three phases in the three-phase power lines work together through alternating current with a 120° phase difference to achieve efficient energy transmission and power output, thereby realizing the transmission of electrical energy.

[0049] The three-phase terminals are encapsulated by copper busbar bending and injection molding, and fixed with bolts to ensure the stability of high current transmission and low contact resistance.

[0050] The neutral terminal is used to connect the neutral line to form a complete circuit; the neutral terminal may participate in the grounding or fault current return path.

[0051] The three-phase terminals can be fixed with bolts to ensure mechanical strength and conductivity.

[0052] The neutral terminal may share a fixing structure with the three-phase terminals to simplify installation.

[0053] Understandably, eliminating the traditional separate terminal block on the motor side and integrating the three-phase terminals of the two motors onto the same terminal block body 2 simplifies the layout and saves space.

[0054] It is understandable that the separate design of the three-phase terminals and neutral terminals in related technologies requires independent terminal blocks and occupies a lot of space. In this embodiment, the three-phase terminals, neutral terminals and electrical control terminals are integrated into a single terminal block body 2, and the left motor lead wire 8 and the right motor lead wire 9 are directly connected through copper busbars, reducing intermediate links and achieving lightweighting and space optimization.

[0055] In one embodiment, please refer to Figure 1 The integrated terminal block further includes a first fixing member 1, which is used to fasten the three-phase terminals and the neutral terminal to the terminal block body 2.

[0056] It is understood that the three-phase terminals and the neutral terminal are fastened to the terminal block body 2 by the first fastener 1 to ensure mechanical strength and conductivity.

[0057] In one embodiment, please refer to Figure 1 and Figure 5 The integrated terminal block also includes a sealing ring 7 and a main housing 12, wherein the sealing ring 7 and the main housing 12 are pressed together to form an end face seal.

[0058] This also includes the main enclosure 12, with the mounting surface of the integrated terminal block pressed against the terminal block mounting surface 19 on the main enclosure 12.

[0059] It is understandable that the sealing ring 7 is installed on the mounting surface of the terminal block body 2, and the terminal block body 2 is fixed to the main housing 12 by bolts, pressing the sealing ring 7 to form an end face seal and improve the sealing effect.

[0060] In one embodiment, please refer to Figure 1 and Figure 2 The integrated terminal block contains an electrical control cavity 20 and a motor cavity, and the sealing ring 7 is used to isolate the electrical control cavity 20 from the motor cavity.

[0061] Understandably, the sealing ring 7 is used to isolate the electronic control cavity 20, the left motor cavity 17, and the right motor cavity 18, preventing oil leakage from the left motor cavity 17 and the right motor cavity 18 into the electronic control cavity 20, which would result in insufficient creepage clearance of the electronic control cavity 20 and insulation failure; at the same time, it avoids the risk of cavitation and lubrication failure caused by reduced oil in the left motor cavity 17 and the right motor cavity 18.

[0062] In one embodiment, the integrated terminal block further includes a smart fuse 4, which is integrated into the terminal block body 2.

[0063] It also includes a smart fuse fixing bolt 5 and a smart fuse fixing nut 6, which directly fix the smart fuse 4 to the terminal block body 2.

[0064] This also includes a copper busbar, which is bent and then embedded into the terminal block body 2 to form an integrated structure of copper busbar injection molding and encapsulation. The smart fuse 4 can be integrated with the copper busbar injection molding and encapsulation to avoid the loosening risk of traditional external fuses.

[0065] The copper busbar is in direct contact with the conductive end of the smart fuse 4 and is locked in place by the smart fuse fixing bolt 5.

[0066] Among them, the smart fuse 4 can use fast-blow fuse material, and the response time of the smart fuse 4 can be less than 10ms to prevent the motor windings from overheating.

[0067] Understandably, installing smart fuse 4 on only two of the three phases reduces the number of fuses by 33% compared to installing smart fuse 4 on all three phases. Furthermore, the space of the integrated terminal block is optimized, reducing additional installation space and making it suitable for compact motor systems.

[0068] It should be noted that the sealing ring 7 inside the integrated terminal block can also be used to prevent oil from corroding the contacts of the smart fuse 4, thereby improving the reliability of the integrated terminal block and extending its lifespan.

[0069] It should be noted that a pluggable interface can be reserved on the terminal block body 2 to facilitate the replacement of smart fuses 4 with different rated currents. At the same time, a temperature sensor can be embedded near the fuse to monitor the fuse status in real time.

[0070] In one embodiment, please refer to Figure 6 The integrated terminal block is also provided with three three-phase terminals for the left motor and three three-phase terminals for the right motor. Any two of the three three-phase terminals for the left motor are connected to the smart fuse 4, and any two of the three three-phase terminals for the right motor are connected to the smart fuse 4.

[0071] Understandably, in the event of a three-phase overcurrent in the left and right motors, the intelligent fuse 4 will disconnect any faulty phase terminal. If only two phase terminals are connected and the faulty phase terminal is not connected to the fuse, the two phase terminals equipped with the intelligent fuse 4 can be disconnected, thereby disconnecting the faulty phase terminal that is not connected to the fuse.

[0072] In this embodiment, when any phase terminal fails, overcurrent protection can be achieved by disconnecting the two phase terminals connected to the smart fuse 4. The smart fuse 4 only needs to cover two of the three phases. When any phase experiences an overcurrent, the smart fuse 4 will blow, thus cutting off the fault circuit.

[0073] In one embodiment, the integrated terminal block further includes a second fixing member, through which the smart fuse 4 is connected to the left motor three-phase terminal and the right motor three-phase terminal.

[0074] The second fastener may include a smart fuse fixing bolt 5 and a smart fuse fixing nut 6, used to fix the smart fuse 4 to at least any two phases of the left three-phase terminal and at least any two phases of the right three-phase terminal.

[0075] In one embodiment, the integrated terminal block further includes a main housing 12 and a plurality of isolation plates 16, wherein the plurality of isolation plates 16 and the main housing 12 enclose a plurality of isolation cavities.

[0076] Among them, the isolation plate 16 is used for shielding to prevent electromagnetic interference from affecting the operating accuracy of the smart insurance 4.

[0077] In the integrated terminal block, the main housing 12 and the isolation plate 16 work together to form multiple isolation cavities to achieve high and low voltage isolation, shielding and sealing protection.

[0078] The main housing 12 serves as the mounting base for the terminal block system, supporting the terminal block body 2, the motor cavity, and the electrical control cavity 20.

[0079] The internal partition and the isolation plate 16 work together to form the following independent cavities: left motor cavity 17, right motor cavity 18, and electrical control cavity 20. The left motor cavity 17 and right motor cavity 18 are used to accommodate the motor and lubrication medium, and the electrical control cavity 20 is used to house high-voltage electrical control components, including but not limited to the inverter interface.

[0080] The isolation cavity is formed by an isolation plate 16 and is used to protect low-voltage signal components, including but not limited to left-hand transformer connector 10 and right-hand transformer connector 13.

[0081] The integrated terminal block also includes a terminal block mounting surface 19, which is pressed against the sealing ring 7 to prevent leakage between the left motor cavity 17, the right motor cavity 18, and the electrical control cavity 20.

[0082] Among them, the isolation plate 16 can be a 1mm stainless steel plate injection molded and covered on the side of the terminal block, which must meet the shielding effect.

[0083] It is understood that each isolation plate 16 is enclosed by the inner wall of the main housing 12 to form an independent metal shielding cavity. The isolation cavity includes a left-hand transformer isolation cavity and a right-hand transformer isolation cavity. The left-hand transformer isolation cavity is used to isolate the left-hand transformer connector 10 from the high-voltage terminal of the left motor. The high-voltage terminal of the left motor includes the left motor neutral terminal 25, the first left motor three-phase terminal 26, the second left motor three-phase terminal 27, and the third left motor three-phase terminal 28. The right-hand transformer isolation cavity is used to isolate the right-hand transformer connector 13 from the high-voltage terminal of the right motor. The high-voltage terminal of the right motor includes the right motor neutral terminal 21, the first right motor three-phase terminal 22, the second right motor three-phase terminal 23, and the third right motor three-phase terminal 24.

[0084] It should be noted that the isolation plate 16 can also be configured as a detachable structure, or the isolation plate 16 can be made of composite shielding material to adapt to higher frequency interference scenarios.

[0085] In one embodiment, the isolation plate 16 is integrally disposed with the terminal block body 2.

[0086] Among them, the isolation plate 16 can also be integrated with the main housing 12.

[0087] Understandably, the isolation plate 16 can be integrated with the terminal block body 2 or the main housing 12, eliminating the need for additional mounting brackets and simplifying the structural design of the integrated terminal block.

[0088] In one embodiment, please refer to Figure 4 The isolation plate 16 includes a metal spring 29, which is used to contact and electrically connect with the main housing 12.

[0089] Among them, the metal spring 29 is integrated into the edge of the isolation plate 16 to ensure conductive contact with the main housing 12.

[0090] Among them, the surface of the metal spring 29 is plated with gold or nickel to adapt to high humidity environment and play a role in corrosion protection.

[0091] Among them, the metal spring 29 is made of elastic conductive material, which establishes a low impedance path between the isolation plate 16 and the main housing 12 to ensure smooth conduction of shielding current.

[0092] Among them, the metal spring 29 can be designed with pre-compression deformation to compensate for the machining tolerance of the main housing 12 and avoid shielding failure due to assembly gap.

[0093] The metal spring 29 can be fixed to the edge of the isolation plate 16 by stamping or welding, and is injection molded into the terminal block body 2 together with the isolation plate 16.

[0094] The isolation plates 16 on both sides of the main housing 12 are equipped with metal springs 29 to ensure the consistency of electromagnetic shielding performance of the dual motor cavities.

[0095] Understandably, by setting bimetallic springs 29 in parallel in critical areas, fault tolerance is improved.

[0096] Understandably, the metal spring 29 electrically connects the isolation plate 16 to the metal wall of the main housing 12 to form a continuous conductor to constitute a Faraday cage, effectively isolating high-frequency interference.

[0097] It should be noted that the elastic deformation of the metal spring 29 of the isolation plate 16 will not affect the compression rate of the sealing ring 7, and the compression range of the sealing ring 7 can be 20% to 30%. The elastic deformation of the metal spring 29 needs to be adapted to the slight displacement of the integrated terminal block due to thermal expansion or vibration in order to avoid stress concentration or contact detachment.

[0098] In this embodiment, the design of the metal spring 29 solves the problem of low reliability of traditional rigid connection through elastic dynamic connection; the metal spring 29 electrically connects the isolation plate 16 to the metal wall of the main housing 12 to form a continuous conductor to form a Faraday cage, effectively isolating high frequency interference.

[0099] In one embodiment, the integrated terminal block further includes a left-hand variable connector 10 and a right-hand variable connector 13, wherein the left-hand variable connector 10 and the right-hand variable connector 13 are located in different isolation cavities.

[0100] Among them, the left-hand variable connector 10 and the right-hand variable connector 13 are in close contact with the isolation plate 16 through the metal spring 29 to ensure that the potential of the shielding layer is consistent.

[0101] Understandably, the isolation chamber reuses the metal wall of the main housing 12, eliminating the need for an additional shielding cover and saving space.

[0102] In one embodiment, the integrated terminal block further includes a terminal block fixing bolt 3, which fixes the terminal block body 2 to the main housing 12.

[0103] In one embodiment, the integrated terminal block further includes a high-voltage terminal block 11, which is used to connect the three phases of the motor to the high-voltage terminals of the electronic control system to achieve reliable transmission of high current and high voltage.

[0104] According to a second aspect of this disclosure, a motor system is provided that includes an integrated terminal block as described in any of the above embodiments; the motor system has all the beneficial effects of the aforementioned integrated terminal block, which will not be repeated here.

[0105] In one embodiment, the motor system includes a motor body 14, on which motor lead wires for leading out three-phase terminals are integrated. The motor lead wires include a left motor lead wire 8 and a right motor lead wire 9. The left motor lead wire 8 replaces the terminal block structure located on the left motor side, and the right motor lead wire 9 replaces the terminal block structure located on the right motor side, saving two terminal blocks in the motor system, thus saving space and making the layout design and weight reduction easier.

[0106] According to a third aspect of this disclosure, a vehicle is provided that includes the motor system or integrated terminal block of any of the above embodiments, and the vehicle has all the beneficial effects of the motor system or integrated terminal block of any of the embodiments, which will not be repeated here.

[0107] The vehicle may be a gasoline vehicle, a plug-in hybrid vehicle, or a new energy vehicle, etc., and this disclosure does not make any specific restrictions.

[0108] According to a fourth aspect of this application, a method for adjusting a sealing ring 7 is also provided, applied to an integrated terminal block as described in any of the above embodiments, the integrated terminal block including a sealing ring 7 and a main housing 12, the sealing ring 7 being press-fitted with the main housing 12 to form an end face seal, the method for adjusting the sealing ring 7 including:

[0109] S1: The surface difference between the lead wire terminal and the terminal block terminal is calculated by the dimension chain link;

[0110] S2: The deformation opening amount of the integrated terminal block under forced displacement is obtained through analysis;

[0111] S3: Adjust the compression ratio of the end face seal of the sealing ring 7 based on the size of the deformation opening.

[0112] The step S1, which verifies the surface difference between the sealing ring 7 and the main housing 12 by checking the dimensional chain link, includes:

[0113] S11: Identify key links in the chain:

[0114] S12: Calculate the surface difference between the lead wire terminal and the terminal block terminal through tolerance superposition analysis based on the critical link.

[0115] The terminal block includes any one of the following: right motor neutral terminal 21, first right motor three-phase terminal 22, second right motor three-phase terminal 23, third right motor three-phase terminal 24, left motor neutral terminal 25, first left motor three-phase terminal 26, second left motor three-phase terminal 27, and third left motor three-phase terminal 28.

[0116] Among them, the lead wire terminal is part of the motor lead wire 15 and is used to connect to the terminal block body 2.

[0117] The surface difference between any terminal block and the lead wire terminal is the same. This surface difference can be calculated by selecting any terminal block terminal and the corresponding lead wire terminal. Specifically, this surface difference can be the distance between any terminal block terminal and the corresponding lead wire terminal.

[0118] The step of calculating the surface difference between the lead-out terminal and the terminal block terminal through the dimensional chain links is to quantify the impact of cumulative assembly tolerances on the sealing surface fit, thereby determining the design benchmark for the initial compression rate of the sealing ring 7. The key links include, but are not limited to, tolerances on the electrical control side, terminal block tolerances, and main housing 12 tolerances. Electrical control side tolerances include pin hole position accuracy, mounting surface flatness, and copper busbar profile accuracy. Terminal block tolerances include injection molding shrinkage rate and mounting hole position accuracy. Main housing 12 tolerances include mounting surface flatness and pin hole clearance.

[0119] The step of simulating and analyzing the deformation opening amount under forced displacement of the integrated terminal block is to predict the impact of the deformation of the terminal block body 2 caused by bolt tightening on the sealing surface; for example, the deformation opening amount under forced displacement of 1mm and 3mm is 0.32mm and 0.98mm, respectively.

[0120] Among these measures, the end face seal compression ratio is adjusted to dynamically adapt to the amount of deformation and ensure the effectiveness of the seal; the range of the compression ratio can be, but is not limited to, 20% to 30%.

[0121] In this embodiment, by adjusting the compression ratio of the sealing ring 7 end face seal, the problem of sealing reliability in highly integrated terminal blocks is solved, making it suitable for the harsh operating conditions of motor systems.
