[0002] An on-board motor controller is an electronic device that converts the DC power supplied by the vehicle's power battery into AC power required to drive the motor, and precisely controls the motor's speed, torque, and direction.

[0003] The AC terminal of the vehicle motor controller uses a three-phase adapter. The three-phase adapter is an electrical interface used to connect and distribute three-phase AC power. Its core function is to provide a safe, reliable and convenient three-phase power connection solution.

[0004] Currently, in the AC terminal assembly design of vehicle motor controllers, the three-phase adapter is vertically mounted on the support frame in the up-down direction and fixed to one side of the support frame in the vertical direction, which increases the space occupied in the vertical direction.

[0007] In an optional embodiment of this application, the adapter further includes an interface end, which is connected to one side of the base plate along a second horizontal direction and has an interface, wherein the second horizontal direction is perpendicular to the first horizontal direction. The three-phase adapter assembly also includes an output electrode, which is disposed at the interface.

[0008] In an optional embodiment of this application, the output electrode includes a first output electrode plate, a second output electrode plate, and a third output electrode plate extending vertically downwards outside the interface. The first output electrode plate is electrically connected to the first input electrode plate, the second output electrode plate is electrically connected to the second input electrode plate, and the third output electrode plate is electrically connected to the third input electrode plate.

[0009] In an optional embodiment of this application, the base plate includes a horizontally extending plate portion and a first ear portion, a second ear portion, and a third ear portion that protrude from the plate portion along the same side in a vertical direction and are spaced apart. A first input electrode plate extends from the first ear portion along a first horizontal direction, a second input electrode plate extends from the second ear portion along a first horizontal direction, and a third input electrode plate extends from the third ear portion along a first horizontal direction.

[0010] In the optional embodiment of this application, the first ear, the second ear, and the third ear are located on the same side of the base plate along the first horizontal direction, and a first notch is formed between two adjacent ears; the base plate is provided with a plurality of spaced-apart lower mounting holes.

[0011] A second aspect of this application provides a motor controller, including a current sensor, a support plate, and the aforementioned three-phase adapter assembly. The current sensor is connected to a first input electrode plate, a second input electrode plate, a third input electrode plate, and the support plate, and is located on one side of the support plate in a horizontal first direction. The support plate on the horizontal first direction side is located in an insertion assembly space, between the bottom of the current sensor and the base plate.

[0012] In an optional embodiment of this application, the current sensor is provided with a plurality of spaced-apart mounting holes.

[0013] In an optional embodiment of this application, the motor controller further includes a power module and multiple spaced conductive plates. The support plate has clearance holes, and the power module is connected to the support plate. The power module and the three-phase adapter assembly with a current sensor are located on opposite sides of the clearance holes in a first horizontal direction. The projection of each conductive plate onto the support plate lies within the clearance hole, and the first, second, and third input electrode plates of the adapter are connected to the power module.

[0014] In an optional embodiment of this application, the motor controller further includes a circuit board connected to the support plate and located on one side of the support plate along the vertical direction; the power module is located between the support plate and the circuit board, and the current sensor is located on one side of the circuit board along the first horizontal direction.

[0015] In an optional embodiment of this application, the support plate is provided with a first protrusion and a second protrusion, which are spaced apart and arranged on one side of the support plate in a horizontal first direction, and both extend outward in the horizontal first direction. The first protrusion is located between the first ear and the second ear of the base plate, and the second protrusion is located between the second ear and the third ear of the base plate, with the second ear located between the first protrusion and the second protrusion.

[0016] A third aspect of this application provides a motor module, including a motor and the aforementioned motor controller, wherein the motor controller is disposed above the motor housing.

[0017] The fourth aspect of this application provides a vehicle including a power battery and the aforementioned motor module, wherein the power battery is connected to a motor controller.

[0018] Compared with the prior art, this application has the following beneficial effects: The motor controller provided in this application includes at least a three-phase adapter assembly, a current sensor, and a support plate. The three-phase adapter assembly includes an adapter base, which includes a base plate and a first input electrode plate, a second input electrode plate, and a third input electrode plate. These three input electrode plates are used to introduce three-phase AC power.

[0019] Each input electrode plate extends to the same side along the first horizontal direction and is located on the same side of the vertical direction of the base plate. Together with the base plate, they form an insertion assembly space with an opening in the first horizontal direction. The bracket plate can be inserted into the insertion assembly space along one side of the first horizontal direction.

[0020] That is, the bracket plate and the three-phase adapter are inserted and matched in the horizontal direction, which can save vertical space compared with the existing vertical splicing direction and make fuller use of the assembly space.

[0021] Secondly, the three-phase adapter and the current sensor can be plugged in first, and then plugged in to the bracket plate. Fixed connection points are formed on both sides of the vertical direction of the bracket plate to achieve vertical fixation.

[0022] Furthermore, the motor controller also includes a power module and a circuit board. The power module is used to convert DC power into three-phase AC power and output it to the three-phase adapter. The current sensor is located on one side of the horizontal first direction of the bracket plate (rear-mounted design) and is arranged at intervals with the power module to avoid overlapping with the power module in the vertical projection. This allows the circuit board to occupy more horizontal space, thereby enabling more electronic components to be arranged on the circuit board and further enriching the functions of the motor controller.

[0032] To make the above and other features and advantages of the present invention clearer, the invention will be further described below with reference to the accompanying drawings. It should be understood that the specific embodiments given herein are for the purpose of explanation to those skilled in the art and are exemplary only, not restrictive.

[0033] Furthermore, features specified with "first" or "second" for descriptive purposes only should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Features specified with "first" or "second" may explicitly or implicitly include at least one of the specified features. The description of "multiple" generally means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0034] Figure 1 This is a schematic diagram of a motor module according to one embodiment of the present application. The motor module includes a motor controller 1000 and a motor 2000. The motor controller 1000 is disposed above the housing of the motor 2000.

[0035] The motor 2000 is a three-phase motor, therefore it requires a three-phase AC power supply as its drive power. One of the functions of the motor controller 1000 is to convert the input DC power supply into a three-phase AC power supply to power the motor 2000.

[0036] Figure 2 for Figure 1 A schematic diagram of the AC terminal electrical components of the motor controller 1000. Please refer to [link / reference]. Figure 2 The motor controller 1000 includes a three-phase adapter 100, a current sensor 300, and a support plate 400.

[0037] Figure 3 for Figure 2 A schematic diagram of the assembly of the three-phase adapter assembly 100 and the current sensor 300. Please refer to [the diagram]. Figure 3 The three-phase adapter assembly 100 includes an adapter base 10, which includes a base plate 11 and a first input electrode plate 12, a second input electrode plate 13 and a third input electrode plate 14 connected to the base plate 11.

[0038] The first input electrode 12, the second input electrode 13, and the third input electrode 14 are arranged at intervals, all extending to the same side along the first horizontal direction and located on the same side of the base plate 11 in the vertical direction, and forming an insertion assembly space S1 between them and the base plate 11.

[0039] In this embodiment, the three-phase adapter 100 is used to connect to a three-phase AC power supply and introduce the three-phase AC power supply to the motor 2000. The three-phase adapter 100 includes an adapter 10, which can be mounted on the support plate 400.

[0040] The adapter 10 includes a first input electrode plate 12, a second input electrode plate 13 and a third input electrode plate 14. These three input electrode plates are respectively connected to a single phase of a three-phase AC power supply, such as the U phase, V phase and W phase of a three-phase AC power supply.

[0041] The first input electrode plate 12, the second input electrode plate 13, and the third input electrode plate 14 are arranged at intervals to ensure that each single phase of the three-phase AC power supply is introduced independently.

[0042] Furthermore, all three input electrode pieces extend towards the same side along the first horizontal direction, and are located on the same side of the base plate 11 in the vertical direction, thus forming a vertical insertion and assembly space S1 between the base plate 11 and the base plate 11. This insertion and assembly space S1 has an opening on one side in the first horizontal direction. Specifically, the insertion and assembly space S1 is the vertical space between the base plate 11 and each input electrode piece, and the insertion and assembly space S1 is designed to be open on one side in the first horizontal direction.

[0043] Furthermore, the horizontal first direction side of the support plate 400 can be inserted into the insertion assembly space S1 through the opening of the insertion assembly space S1, so that the base plate 11 of the adapter 10 and the three input electrode plates are respectively located on both sides of the support plate 400 in the vertical direction.

[0044] As can be seen, the three-phase adapter 100 and the bracket plate 400 are assembled by horizontal plugging, which is different from the existing vertical stacking assembly, thus avoiding the occupation of too much vertical space and making full use of the assembly space.

[0045] Figure 4 for Figure 1 A schematic diagram of the AC terminal of the motor controller 1000. Figure 5 for Figure 4 A schematic diagram of the AC terminals of the motor controller 1000 from another perspective. It should be noted that... Figure 4 and Figure 5 Hidden in Figure 2 The circuit board 500 is shown among the various electrical components. Please continue reading. Figure 3 , Figure 4 and Figure 5 In one optional embodiment, the current sensor 300 is connected to the first input electrode 12, the second input electrode 13, the third input electrode 14, and the support plate 400, and is located on one side of the support plate 400 in the first horizontal direction. The support plate 400 is located on one side of the support plate 400 in the first horizontal direction in the insertion assembly space S1, and is between the bottom of the current sensor 300 and the base plate 11.

[0046] In this embodiment, the current sensor 300 is provided with three through holes, which correspond one-to-one to allow the first input electrode plate 12, the second input electrode plate 13 and the third input electrode plate 14 to pass through. The current sensor 300 can detect the magnitude of the current passing through each input electrode plate.

[0047] During the assembly process, the current sensor 300 is first inserted into the three-phase adapter assembly 100, and then the three-phase adapter assembly 100 with the current sensor 300 is inserted into one side of the bracket plate 400. One side of the bracket plate 400 is snapped between the bottom of the current sensor 300 and the base plate 11.

[0048] In some optional embodiments, the current sensor 300 is provided with a plurality of spaced-apart upper mounting holes H3. In this embodiment, the multiple upper mounting holes H3 are used to fix the current sensor 300 and also to fix the upper side of the three-phase adapter assembly 100, thus avoiding the need to add additional mounting holes to the three-phase adapter assembly 100. Figure 4 In the embodiment shown, there are two mounting holes H3, but the number of mounting holes H3 is not limited to this.

[0049] In a further optional embodiment, the base plate 11 is provided with a plurality of spaced-apart lower mounting holes H2. In this embodiment, after the three-phase adapter assembly 100 with current sensor 300 is inserted into one side of the bracket plate 400, it can be fixed vertically on both sides by fastening the fasteners in conjunction with the plurality of upper mounting holes H3 and the plurality of lower mounting holes H2. Compared with the existing vertical single-sided stacking and single-sided fixing scheme, the vertical two-sided fixing scheme has better installation strength.

[0050] exist Figure 5 In the illustrated embodiment, there are three lower mounting holes H2, arranged in a triangular pattern. Of course, the number and distribution of the lower mounting holes H2 are not limited to the illustrated embodiment. It should be noted that the aforementioned fastening components refer to, for example, screws and rivets. Furthermore, in cases where the installation strength requirement is not high, a vertical single-sided fixing scheme can also be adopted, that is, utilizing only the upper mounting holes H3 or the lower mounting holes H2.

[0051] In some alternative embodiments, the base plate 11 includes a horizontally extending plate portion 114 and a first ear portion 111, a second ear portion 112, and a third ear portion 113 that protrude from the plate portion 114 on the same side in a vertical direction and are spaced apart.

[0052] The first input electrode 12 extends from the first ear portion 111 along the first horizontal direction, the second input electrode 13 extends from the second ear portion 112 along the first horizontal direction, and the third input electrode 14 extends from the third ear portion 113 along the first horizontal direction.

[0053] In this embodiment, the horizontally extending plate portion 114 has three ears extending from the same side in the vertical direction, thereby forming the base plate 11. These three ears are arranged at intervals and correspond to the first ear portion 111, the second ear portion 112, and the third ear portion 113, respectively.

[0054] The first input electrode 12, the second input electrode 13, and the third input electrode 14 are connected one-to-one to the first ear portion 111, the second ear portion 112, and the third ear portion 113 protruding from the same side in the vertical direction, and all extend to the same side in the first horizontal direction. Thus, the first input electrode 12, the second input electrode 13, and the third input electrode 14 are arranged parallel to and spaced apart from the plate portion 114 in the vertical direction, that is, the input electrode 12, the ear portion, and the plate portion 114 together form an insertion assembly space S1 with an opening on one side in the first horizontal direction.

[0055] In one optional embodiment, the first ear portion 111, the second ear portion 112, and the third ear portion 113 have the same shape. Specifically, the first ear portion 111, the second ear portion 112, and the third ear portion 113 are configured as bent structures with an opening on one side in a horizontal first direction. For example, the first ear portion 111, the second ear portion 112, and the third ear portion 113 are configured as U-shaped, semi-circular, etc., with the opening direction on one side in the horizontal direction. In one optional embodiment, a plurality of lower mounting holes H2 are all located at the plate portion 114.

[0056] In one optional embodiment, the first ear portion 111, the second ear portion 112, and the third ear portion 113 are aligned and arranged side-by-side with spacing in a horizontal second direction. Thus, the ends of the first input electrode plate 12, the second input electrode plate 13, and the third input electrode plate 14 connected to the respective ear portions are aligned in the horizontal second direction. Of course, the relative positions of the first ear portion 111, the second ear portion 112, and the third ear portion 113 in the horizontal second direction can be adaptively adjusted according to the side shape of the support plate 400, and are not limited thereto.

[0057] In a further optional embodiment, the first input electrode 12, the second input electrode 13, and the third input electrode 14 have the same length in the first horizontal direction, that is, the suspension ends of the input electrode 12 extending from the ear are aligned. Of course, the lengths of the first input electrode 12, the second input electrode 13, and the third input electrode 14 in the first horizontal direction can be adaptively adjusted according to assembly requirements, and are not limited thereto.

[0058] In a further optional embodiment, the first ear portion 111, the second ear portion 112, and the third ear portion 113 have equal vertical protrusion heights, and the vertical spacing between the first input electrode plate 12, the second input electrode plate 13, and the third input electrode plate 14 and the plate portion 114 is equal. Of course, the protrusion height of each ear portion and the spacing between each input electrode plate and the plate portion 114 can be adaptively adjusted according to the side thickness of the support plate 400.

[0059] Figure 6 for Figure 4A schematic diagram of the AC terminals of the motor controller 1000 from another perspective. Please refer to... Figure 6 In some optional embodiments, the first ear portion 111, the second ear portion 112 and the third ear portion 113 are located on the same side of the base plate 11 along the first horizontal direction, and a first notch C1 is formed between two adjacent ears.

[0060] In this embodiment, the first ear portion 111, the second ear portion 112, and the third ear portion 113 are aligned and arranged on the same side of the base plate 11 in the first horizontal direction. Specifically, as shown... Figure 3 As shown, the ears are located on the outermost side of the base plate 11 in the first horizontal direction, preventing the base plate 11 from protruding beyond the ears on one side in the first horizontal direction, thereby reducing the space occupied in the first horizontal direction. In addition, since the three ears are aligned along the edge in the first horizontal direction and spaced apart in the second horizontal direction, a first notch C1 is formed between the first ear 111 and the second ear 112, and another first notch C1 is formed between the second ear 112 and the third ear 113.

[0061] See Figure 5 and Figure 6 The support plate 400 is provided with a first protrusion 410 and a second protrusion 420. The first protrusion 410 and the second protrusion 420 are arranged at intervals on one side of the support plate 400 in the first horizontal direction, and both extend outward in the first horizontal direction.

[0062] The first protrusion 410 is located between the first ear portion 111 and the second ear portion 112, the second protrusion 420 is located between the second ear portion 112 and the third ear portion 113, and the second ear portion 112 is located between the first protrusion 410 and the second protrusion 420.

[0063] In this embodiment, the first protrusion 410 and the second protrusion 420 protruding outward from the bracket plate 400 are provided with mounting holes that cooperate with the housing of the motor 2000, and the spaced first protrusion 410 and the second protrusion 420 are separated by a second notch C2.

[0064] The first protrusion 410 is inserted into a first notch C1 between the first ear 111 and the second ear 112, the second ear 112 is inserted into a second notch C2 between the first protrusion 410 and the second protrusion 420, and the second protrusion 420 is inserted into another first notch C1 between the second ear 112 and the third ear 113.

[0065] Thus, after the three-phase adapter assembly 100 is plugged into the bracket plate 400 in the horizontal direction, the spaced first ear 111, second ear 112 and third ear 113 and the spaced first protrusion 410 and second protrusion 420 form a structure that is nested with each other and alternately arranged in the second horizontal direction, which is conducive to plugging and assembly and can also save space occupied in the horizontal direction.

[0066] See Figure 2 In some optional embodiments, the motor controller 1000 further includes a power module 600 and a plurality of spaced conductive sheets 700.

[0067] The bracket plate 400 is provided with a clearance hole H4. The power module 600 is connected to the bracket plate 400. The power module 600 and the three-phase adapter assembly 100 with current sensor 300 are located on opposite sides of the clearance hole H4 in the first horizontal direction.

[0068] The projection of each conductive sheet 700 on the bracket plate 400 is located within the clearance hole H4, and the first input electrode sheet 12, the second input electrode sheet 13 and the third input electrode sheet 14 of the adapter 10 are connected to the power module 600.

[0069] In this embodiment, the power module 600 is connected to the first input electrode plate 12, the second input electrode plate 13 and the third input electrode plate 14 of the three-phase conversion component 100 in the DC and AC terminals of the motor controller 1000, and is used to convert DC power into three-phase AC power.

[0070] Each input electrode is connected to the power module 600 via a conductive sheet 700. There are no fewer than three conductive sheets 700. The conductive sheets 700 are made of conductive materials, such as copper alloy.

[0071] The support plate 400 has a clearance hole H4. The power module 600, the adapter 10, and the current sensor 300 are located on opposite sides of the clearance hole H4 in the first horizontal direction. That is, the power module 600 is located on one side of the clearance hole H4 in the first horizontal direction, and the adapter 10 and the current sensor 300 are located on the other side of the clearance hole H4 in the first horizontal direction. The projection of each conductive sheet 700 on the support plate 400 is located within the clearance hole H4, which facilitates the assembly of the conductive sheet 700 connected between the input electrode sheet of the adapter 10 and the power module 600 through the clearance hole H4.

[0072] It should be understood that the current sensor 300 and the power module 600 located on both sides of the clearance hole H4 are spaced apart in the first horizontal direction, so the current sensor 300 and the power module 600 do not overlap in the vertical direction.

[0073] In a further optional embodiment, the motor controller 1000 also includes a circuit board 500 connected to the bracket plate 400 and located on one side of the bracket plate 400 in the vertical direction.

[0074] The power module 600 is located between the bracket plate 400 and the circuit board 500, and the current sensor 300 is located on one side of the circuit board 500 along the first horizontal direction.

[0075] In this embodiment, the bracket plate 400 has multiple mounting posts protruding upwards. These mounting posts are provided with mating holes for assembly with the circuit board 500, and the circuit board 500 and the bracket plate 400 are vertically spaced to form a space for accommodating the power module 600, which is located between the bracket plate 400 and the circuit board 500.

[0076] Since the current sensor 300 is arranged on the side in the first horizontal direction and does not overlap with the power module 600 in the vertical direction, the circuit board 500 can be extended horizontally to obtain a larger area. This allows more electronic components to be arranged on the circuit board 500, thereby enabling the circuit board 500 to achieve richer functions.

[0077] See Figure 3 and Figure 4 In some optional embodiments, the adapter 10 further includes an interface end 15, which is connected to one side of the base plate 11 along the second horizontal direction and has an interface H1. The three-phase adapter assembly 100 also includes an output electrode 20, which is disposed at the interface H1.

[0078] In this embodiment, the base plate 11 is provided with an interface end 15 on one side in the second horizontal direction. An interface H1 is provided in the interface end 15. An output electrode 20 is installed in the interface H1. The output electrode 20 can be connected to the motor 2000 to lead out the three-phase AC power introduced through the three-phase adapter 100 to the motor 2000.

[0079] In practical applications, interface H1 is not completely blocked by bracket plate 400. After the three-phase adapter component 100 is plugged into bracket plate 400, at least part of the upper opening of interface H1 is exposed, which facilitates wiring.

[0080] Furthermore, the output electrode 20 includes a first output electrode piece 21, a second output electrode piece 22, and a third output electrode piece 23 that extend downward in the vertical direction outside the interface H1.

[0081] The first output electrode 21 is electrically connected to the first input electrode 12, the second output electrode 22 is electrically connected to the second input electrode 13, and the third output electrode 23 is electrically connected to the third input electrode 14.

[0082] In this embodiment, the number of input electrode plates and output electrode plates in the three-phase adapter assembly 100 are equal and they are connected in a one-to-one correspondence. Each input electrode plate introduces each single phase of the three-phase AC power supply from the power module 600, and each output electrode plate leads each single phase of the three-phase AC power supply out to the motor 2000.

[0083] Another aspect of this application provides a vehicle that includes a power battery and the aforementioned motor module, the power battery being connected to a motor controller 1000.

[0084] In this embodiment, the vehicle is a new energy vehicle, such as a hybrid vehicle or a pure electric vehicle. The power battery provides DC power, which is converted into three-phase AC power by the motor controller 1000 and supplied to the motor 2000.

[0085] It should be noted that the aforementioned first and second horizontal directions define the horizontal direction. The first and second horizontal directions are perpendicular to each other. Here, one of the first and second horizontal directions is roughly in the vehicle length direction, and the other is roughly in the vehicle width direction. The vertical direction, which is perpendicular to the first and second horizontal directions, can refer to the vehicle height direction.

[0086] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
