When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0044] The utility model proposes a motor controller, which aims to provide a first installation position and a second installation position on the bottom and side of a shell body so that the cable has two different outlet positions and outlet directions from the bottom and side of the shell body, thereby achieving different motor controllers when connecting cables. The matching outlet directions and outlet positions can be freely selected, thereby improving the compatibility of the motor controller.

[0045] Please refer to Figures 1 to 7 The specific structure of the motor controller 10 proposed by the utility model will be described in a specific embodiment below. In one embodiment of the utility model, the motor controller 10 includes:

[0046] A housing 1, wherein a housing cavity 11 is formed in the housing 1, and the housing cavity includes a first cavity 111 and a second cavity 112;

[0047] A water-cooling component 2, wherein the water-cooling component 2 is disposed in the first cavity 111;

[0048] A driving assembly 3, wherein the driving assembly 3 is disposed in the first cavity 111 and is located on one side of the water-cooling component 2;

[0049] A power module 4, wherein the power module 4 is disposed in the second cavity 112 and located on the other side of the water-cooling component 2;

[0050] The terminal component 5 is arranged in the first cavity 111, and the terminal component 5 is formed with a first terminal 5212 corresponding to the first installation position, so that the cable 6 is electrically connected to the first terminal 5212 through the first installation position; or, the terminal component 5 is formed with a second terminal 532 corresponding to the second installation position 122, so that the cable 6 is electrically connected to the second terminal 532 through the second installation position 122.

[0051] In this embodiment, the motor controller 10 includes a shell 1 and a water-cooling component 2 arranged in the shell 1, wherein a accommodating cavity 11 is formed in the shell 1, and the accommodating cavity 11 includes a first cavity 111 and a second cavity 112, and the water-cooling component 2 is installed in the first cavity 111. It can be understood that the first cavity 111 and the second cavity 112 are arranged in sequence in the height direction of the shell 1, that is, the first cavity 111 is arranged above the second cavity 112.

[0052] It should be noted that the water-cooling component 2 can be installed in the accommodating cavity 11 by means of screws or welding, so as to ensure the installation stability of the water-cooling component 2.

[0053] The drive assembly 3 is installed in the first cavity 111 and is arranged on one side of the water-cooling component 2. In this way, the drive assembly 3 is heat-dissipated by the water-cooling component 2, and the heat generated by the drive assembly 3 can be quickly taken away by the water-cooling component 2, ensuring the normal use of the drive assembly 3.

[0054] The power module 4 is installed in the second cavity 112 and is located on the other side of the water-cooling component 2. With this arrangement, the power module 4 is heat-dissipated by the water-cooling component 2, and the heat generated by the power module 4 is quickly taken away by the water-cooling component 2. By respectively arranging the drive component 3 and the power module 4 on both sides of the water-cooling component 2, the water-cooling component 2 can simultaneously take away the heat generated by the drive component 3 and the power module 4, and the heat is dissipated by sharing a water channel between the drive component 3 and the power module 4. The overall size of the entire motor controller 10 is small, the occupied space is reduced, and the structure is compact.

[0055] The motor controller 10 further includes a terminal block member 5 , wherein the terminal block member 5 is installed in the first cavity 111 , and a first installation position is provided at the bottom of the housing 1 and a second installation position 122 is provided at the side of the housing 1 .

[0056] It should be noted that both the first installation position and the second installation position 122 are connected to the accommodating cavity 11 . It can be considered that both the first installation position and the second installation position 122 are connected to the accommodating cavity 11 .

[0057] In one case, if Figure 4 As shown, the terminal member 5 is formed with a first terminal 5212 corresponding to the first installation position, so that the cable 6 is electrically connected to the first terminal 5212 through the first installation position, that is, the cable 6 at this time has a wire outlet mode perpendicular to the bottom of the shell 1.

[0058] In another case, if Figure 7As shown, the terminal member 5 is formed with a second terminal 532 corresponding to the second installation position 122, so that the cable 6 is electrically connected to the second terminal 532 through the second installation position 122, that is, the cable 6 at this time has a wire outlet method perpendicular to the side of the shell 1.

[0059] By setting a first mounting position at the bottom of the shell 1 and a second mounting position 122 on the side of the shell 1, and cooperating with the terminal member 5 corresponding to the first mounting position or the second mounting position 122, the cable 6 has two different outlet positions and outlet directions from the bottom of the shell 1 or the side of the shell 1. Through this design, the motor controller can be compatible with both horizontal and vertical directions. When the motor controller 10 is connected to the cable 6, it can meet different installation positions, thereby improving the compatibility and installation flexibility of the motor controller 10.

[0060] Please refer to Figures 2 to 7 In an optional embodiment, the terminal component 5 includes a copper busbar assembly 51 and a terminal frame 52.

[0063] As described above, the cable 6 connected to the motor controller has two different outlet positions and outlet directions from the bottom of the shell 1 or the side of the shell 1. Through this design, the motor controller can be compatible with both horizontal and vertical directions. When the motor controller 10 is connected to the cable 6, it can meet different installation positions, thereby improving the compatibility and installation flexibility of the motor controller 10.

[0064] It should be noted that the connection between the copper busbar assembly 51 and the terminal frame 52 and the cable 6 can be achieved by fasteners such as screws, so that the cable 6 and the copper busbar assembly 51 are in contact and matched, thereby achieving electrical conduction between the two.

[0065] It should be noted that the copper busbar assembly 51 includes an output copper busbar assembly 511 and an input copper busbar assembly 512. When the terminal assembly is used for horizontal wiring, the shape of the copper busbar assembly in the terminal assembly is adapted to horizontal wiring. When the terminal assembly 5 is used for vertical wiring, the shape of the copper busbar assembly 51 in the terminal assembly 5 is adapted to vertical wiring. The shapes of the copper busbar assembly 51 corresponding to the two wiring conditions are different.

[0066] Among them, there are multiple first terminal 5212 and first wire tube 5213 or second terminal 532 and second wire tube 533, and multiple first terminal 5212 or multiple second terminal 532 are arranged at intervals on the terminal frame 52. Similarly, there are multiple groups of cables 6, and each cable 6 passes through each first wire tube 5213 or each second wire tube 533 in turn and is respectively connected to each first terminal 5212 or each second terminal 532. Moreover, there are also a plurality of first copper bar connection ends 5214 and second copper bar connection ends 534, and the plurality of first copper bar connection ends 5214 and second copper bar connection ends 534 are arranged at intervals on the terminal frame 52. Similarly, there are also a plurality of output copper bar assemblies 511 and input copper bar assemblies 512. In one case, each output copper bar assembly 511 and each input copper bar assembly 512 are respectively installed on each first copper bar connection end 5214, or, in another case, each output copper bar assembly 511 and each input copper bar assembly 512 are respectively installed on each second copper bar connection end 534. It should be further explained that the output copper bar assembly 511 and the input copper bar assembly 512 are prior art, and this application will not go into details here.

The opening direction of the first threading opening 521a is set toward the bottom of the shell 1 and is connected to the first through hole. The copper busbar assembly 51 is installed on the first copper busbar connection end 5214. Therefore, the cable 6 is connected to the copper busbar assembly 51 after passing through the first through hole and the first threading opening 521a in sequence. By installing the copper busbar assembly 51 on the vertical terminal frame 52, and the cable 6 can also extend into the shell 1 through the first threading port 521a and the first through hole to achieve conductive connection with the copper busbar assembly 51, such an arrangement can enable smooth wiring between the copper busbar assembly 51 and the cable 6, and facilitate wiring between the copper busbar assembly 51 and the cable 6. Not only is the wiring convenient, but the structure is simple and compact, and a flexible installation method between the copper busbar assembly 51 and the cable 6 is achieved.

Therefore, the cable 6 can also extend into the shell 1 through the second threading port 53a and the second through hole to achieve conductive connection with the copper busbar assembly 51. Such a configuration can enable smooth wiring between the copper busbar assembly 51 and the cable 6, and facilitate wiring between the copper busbar assembly 51 and the cable 6. Not only is the wiring convenient, but the structure is simple and compact, and a flexible installation method between the copper busbar assembly 51 and the cable 6 is achieved.

[0074] In some cases, the copper busbar assembly 51 may be connected to the horizontal terminal frame 53 by an injection molding process.

The coolant enters the water channel cavity through the water inlet port to take away the heat generated by the power module 4 and the drive component 3 through the water outlet port, thereby realizing the heat dissipation treatment of the drive component 3 and the power module 4 at the same time.

[0093] Specifically, in order to facilitate the circulation of the coolant in the water channel cavity, the outer wall of the shell 1 is provided with a water inlet port and a water outlet port which are spaced apart, and the water channel cavity is respectively connected to the water inlet port and the water outlet port. The coolant enters the water channel cavity from the water inlet port and flows out from the water outlet port, thereby realizing heat exchange between the coolant in the water channel cavity and the cooling system of the entire vehicle.

[0094] It should be noted that the water inlet port and the water outlet port can be arranged close to the outer peripheral wall of the first cavity 111, or close to the outer peripheral wall of the second cavity 112. The water inlet port and the water outlet port can also be respectively located on both sides of the housing of the motor controller. In the process of the coolant flowing in the water channel cavity, the coolant takes away the heat generated by various components such as the drive assembly 3 and the power module 4 during operation, thereby improving the heat dissipation efficiency of the water-cooled component 2.

[0095] It is understandable that the drive assembly 3 is attached to the water-cooling plate 21, so that the water-cooling plate 21 has a better heat dissipation effect. It should be further explained that the water-cooling plate 21 is an integrated structure, which ensures structural strength and stability, and has good cooling and temperature reduction while avoiding the risk of water leakage in the water channel heat dissipation method.

[0096] Please refer to Figure 1 In an optional embodiment, the driving component 3 includes a driving board 31 and an IGBT module 32, the IGBT module 32 is attached to the water-cooling plate 21, and the driving board 31 is connected to the side of the IGBT module 32 away from the water-cooling plate 21, so as to dissipate heat for the IGBT module 32 through the water-cooling component 2, and then quickly take away the heat generated by the IGBT module 32 during operation through the water-cooling component 2.

[0097] It should be noted that the IGBT module can be installed on the water cooling plate 21 by means of screws or the like, and of course other methods are also possible, and the present application does not impose any limitation thereto.

[0098] Please refer to Figure 2 and Figure 5 In an optional embodiment, the motor controller 10 also includes a heat conductor 7, which is installed in the second cavity 112, one side of the heat conductor 7 is in contact with the bottom of the water channel cavity, and the power module 4 is installed on the other side of the heat conductor. The heat conductor 7 helps to improve the heat dissipation effect of the water cooling component on the power module 4.

[0099] The power module 4 can be installed on the heat conductive member 7 by pasting or welding, or other methods. This application does not make any limitation here.

[0100] Optionally, the heat conducting member is a ceramic substrate.

[0101] The utility model further provides a vehicle, the vehicle comprising a motor and a motor controller 10 as described in any one of the above items, the motor being connected to the motor controller 10. Since the specific structure of the motor controller 10 in the vehicle refers to the above embodiment, it at least has all the beneficial effects brought by the technical solutions of the above embodiment, which will not be described one by one here.

[0102] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
