As shown in fig. 1, the motor controller 10 includes a box 11, a motor power module 12 and an installation position 13, the motor power module 12 and the installation position 13 are both disposed in the box 11, and the installation position 13 is used for installing a voltage boosting assembly 21, so as to implement matching of the voltage boosting function of the motor controller 10.
Specifically, the box 11 may include a bottom cover 111, a middle box 112 and an upper cover 113, the middle box 112 is hollow to form the accommodating cavity 1121, and two openings at two ends form an opening of the accommodating cavity 1121, the bottom cover 111 is disposed at one end of the middle box 112 to seal the opening at the end, and the upper cover 113 is disposed at the other end of the middle box 112 to seal the opening at the end. The motor power module 12 and the mounting position 13 are both located in the accommodating cavity 1121 of the middle box 112, and further the structure in the accommodating cavity 1121 is accommodated and protected by the middle box 112.
The case 11 as a whole may be provided in a rectangular parallelepiped shape, that is, the middle case 112 may be provided in a rectangular parallelepiped shape. Of course, the entire case 11 may be provided in other shapes, such as a square shape, a cylindrical shape, and the like, without specific limitation.
More specifically, the housing 11 is provided with a power interface (not shown), and the power interface is electrically connected to the structure inside the housing 11, and further electrically connected between the structure inside the housing 11 and the structure outside the motor controller 10 through the power interface. Wherein, power source can connect external battery, and then for the structure power supply in box 11. The number of the power interfaces can be one or more, and can be set according to actual requirements. In combination with the above embodiments, the power interfaces may be disposed on a sidewall of the middle box 112, and when the number of the power interfaces is two or more, the power interfaces may be disposed on the same sidewall of the middle box 112 at intervals.
Specifically, the motor power module 12 is used in connection with an electric motor within a vehicle to drive the motor. The motor in the vehicle is not part of the motor controller 10, and the motor power module 12 may be electrically connected to the motor through a connection line, so as to realize driving control of the motor. In combination with the above, the motor power module 12 is connected to an external battery through a power interface, and further, the external battery supplies power to the motor power module 12. The motor power module 12 may be directly connected to the power interface, so as to directly connect the motor power module 12 to the battery, and at this time, the motor power module 12 may be directly connected to the battery. The motor power module 12 may also be connected to the power interface through other electrical components, thereby indirectly connecting the motor power module 12 to the battery.
Specifically, with reference to fig. 4 and 5, the mounting location 13 is reserved in the box 11, the mounting location 13 is used for mounting the voltage boost assembly 21, and when the voltage boost assembly 21 is mounted in the box 11, the voltage boost assembly 21 is electrically connected between the power interface and the motor power module 12, so as to boost the electrical signal input from the power supply to the motor power module 12.
More specifically, the installation position 13 may be an installation cavity reserved in the box body 11, and when the boosting assembly 21 is installed in the installation position 13, the boosting assembly 21 is located in the installation cavity, and the size of the installation cavity may be adapted to the size of the boosting assembly 21. When the pressure boosting assembly 21 needs to be installed, the upper cover 113 or the bottom cover 111 of the box body 11 can be opened, the pressure boosting assembly 21 is installed on the installation position 13, and then the upper cover 113 or the bottom cover 111 is closed to realize sealing. After the boosting assembly 21 is installed, the boosting assembly 21 can be further connected with other electrical elements, so that the boosting assembly 21 is ensured to normally realize functions. Of course, in other embodiments, the mounting location 13 is electrically connected to other electrical components in the motor controller 10 in advance, and the voltage boost assembly 21 is automatically electrically connected to other components after the voltage boost assembly 21 is mounted to the mounting location 13.
After the boosting assembly 21 is electrically connected between the power interface and the motor power module 12, the power supply inputs the electrical signal into the boosting assembly 21 through the power interface, and the boosting assembly 21 boosts the electrical signal and inputs the boosted electrical signal into the motor power module. In this way, a boost is achieved when the motor controller 10 needs a boost.
In some application scenarios, after the voltage boosting assembly 21 is installed in the motor controller 10, the motor controller 10 has a voltage boosting function, and can be applied to class a vehicles and class B vehicles. When the boosting assembly 21 is not installed in the motor controller 10, the motor controller 10 does not have a boosting function, and can be applied to a class A0 vehicle and a class a vehicle low profile.
With the above, the motor controller 10 provided by the present application can mount the voltage boosting assembly 21 on the mounting location 13 when voltage boosting is required, thereby implementing the voltage boosting function of the motor controller 10. When the motor controller does not need to boost, the boosting assembly 21 is not installed, and at this time, the motor controller 10 does not have a boosting function. Therefore, the motor controller 10 can select whether to install the boosting component 21 to realize the selection of the boosting function, so as to realize the matching of the boosting function of the motor controller 10.
With continued reference to fig. 4 and fig. 5, in some embodiments, the mounting locations 13 include a first mounting location 131 and a second mounting location 132 that are independently disposed, the boost assembly 21 includes a boost power module 211 and a boost inductor 212, the first mounting location 131 is used for mounting the boost power module 211, and the second mounting location 132 is used for mounting the boost inductor 212.
Specifically, the first mounting position 131 and the second mounting position 132 are independently disposed, and may be disposed at an interval between the first mounting position 131 and the second mounting position 132, and there is no overlap between the first mounting position 131 and the second mounting position 132. In combination with the above, the size of the first mounting position 131 may be adapted to the shape and size of the boost power module 211, and the size of the second mounting position 132 may be adapted to the shape and size of the boost inductor 212, so that the boost power module 211 and the boost inductor 212 can be suitably mounted to the first mounting position 131 and the second mounting position 132.
In combination with the above, the first mounting position 131 and the second mounting position 132 may be electrically connected in advance, and then after the boost power module 211 and the boost inductor 212 are respectively mounted on the first mounting position 131 and the second mounting position 132, the boost power module 211 and the boost inductor 212 may be electrically connected directly. Of course, the first mounting location 131 and the second mounting location 132 may not be electrically connected, but the boosting power module 211 and the boosting inductor 212 may be electrically connected through a connector or the like.
It should be understood that when the boost assembly 21 includes the boost power module 211 and the boost inductor 212, the boost power module 211 and the boost inductor 212 together implement the boosting of the electric signal passing through the boost assembly 21.
In connection with the above embodiments, the motor power module 12 may include a driving motor power module 121 and a generator power module 122. Correspondingly, the motor includes a driving motor and a generator, the driving motor power module 121 is connected with the driving motor, and the generator power module 122 is connected with the generator. The boost power module 211 is disposed at the first mounting position 131, and the boost power module 211 is integrally packaged with the generator power module 122 or the driving motor power module 121.
Specifically, the driving motor power module 121 and the generator power module 122 are disposed independently, that is, there is no common structure between the driving motor power module 121 and the generator power module 122, and they are disposed at intervals. The driving motor and the generator are also independently arranged at intervals, the driving motor power module 121 is electrically connected with the driving motor through a connecting piece, and the generator power module 122 is electrically connected with the generator through another connecting piece.
More specifically, when motor controller 10 includes boost power module 211, boost power module 211 may be integrally packaged with either generator power module 122 or drive motor power module 121. In this embodiment, the first installation position 131 corresponding to the boost power module 211 is integrally disposed with any one of the driving motor power module 121 or the generator power module 122, so that the boost power module 211 is disposed on the first installation position 131 to implement integrated packaging. It should be understood that fig. 5 merely illustrates the placement of the boost power module 221 separately from the drive motor power module 121 with respect to the generator power module 122, and does not illustrate the structure of the integrated package.
Referring to fig. 6 and 7, fig. 6 is a schematic diagram of an arrangement of the driving motor power module 121, the generator power module 122, and the boost power module 211 of the motor controller 10 provided in the present application, and fig. 7 is a schematic diagram of another arrangement of the driving motor power module 121, the generator power module 122, and the boost power module 211 of the motor controller 10 provided in the present application.
The boost power module 211, the generator power module 122, and the driving motor power module 121 may include a plurality of power chips. For example, the driving motor power module 121 and the generator power module 122 may include six power chips, and the boost power module 211 may include two power chips.
In conjunction with fig. 6, when the booster power module is not integrally packaged with the drive motor power module 121 or the generator power module 122, the chip of the booster power module, the chip of the drive motor power module 121, and the chip of the generator power module 122 are each packaged by a separate case.
With reference to fig. 7, when the booster power module 211 and any one of the driving motor power module 121 or the generator power module 122 are integrally packaged, the chip of the booster power module 211 and the chip of any one of the generator power module 122 or the driving motor power module 121 are packaged in the same casing to form an integrated module S, and in this way, the integrated package is realized. The shell of the integrated module S can be provided with joints of different power modules, and then the electric connection between the different power modules and other motor elements is realized through the joints.
It should be understood that, by disposing the boost power module 211 in the motor controller 10 in an integrated package manner, the assembly process of the boost power module 211 can be omitted when the motor controller 10 needs boosting, and the disposition of the boost power module 211 can be conveniently realized.
For the installation of the boost inductor 212, in some embodiments, the windings and the core of the boost inductor 212 are integrally disposed, and the boost inductor 212 is flange-mounted in the second mounting location 132. It should be appreciated that in this embodiment, the windings and cores of boost inductor 212 are integrated to reduce the size of boost inductor 212, thereby facilitating installation. In this case, boost inductor 212 and the flange are part of motor controller 10.
Further, with reference to fig. 4 and 5, the motor controller 10 further includes a cooling liquid channel 14, the cooling liquid channel 14 is disposed through the box 11, the motor power module and the first mounting position 131 are disposed on one side of the cooling liquid channel 14, and the second mounting position 132 is disposed on the other side of the cooling liquid channel 14.
In combination with the above, the cooling liquid passage 14 penetrates the middle box 112 and is further disposed in the middle box 112. Referring to fig. 1, the cooling liquid passage 14 is disposed along the length direction of the middle case 112 and penetrates both side surfaces of the middle case 112. The cooling liquid channel 14 further includes a liquid inlet end 141 and a liquid outlet end 142, so that the cooling liquid is introduced through the liquid inlet end 141 and is discharged from the liquid outlet end 142.
By the mode, the cooling liquid channel 14 has more contact area with the inner cavity of the box body 11, so that the cooling liquid channel 14 can play a better heat dissipation role, and the heat dissipation of the high-power operation of the motor controller 10 is ensured.
Wherein, cooling liquid channel 14 can be the platykurtic setting to divide the inner chamber of box 11 into two sub-chambeies, two sub-chambeies are located the both sides of cooling liquid channel 14 respectively. The motor power module and the first mounting position 131 are disposed on one side of the cooling liquid channel 14 and located in one of the sub-cavities, and the second mounting position 132 is disposed on the other side of the cooling liquid channel 14 and located in the other sub-cavity. In this way, the elements are disposed on two sides of the cooling liquid channel 14, so that heat generated by the elements can be absorbed by the cooling liquid in the cooling liquid channel 14, and further, the heat can be better absorbed through the cooling liquid channel 14.
Further, in some embodiments, the motor power module 12 and the first mounting position 131 are located on the same structural layer, and the first mounting position 131 and the second mounting position 132 are disposed opposite to each other on two sides of the cooling liquid channel 14.
In combination with the above embodiments, the driving motor power module 121, the generator power module 122 and the first mounting position 131 are located on the same structural layer, and the structural layer is disposed adjacent to the cooling liquid channel 14. Because the driving motor power module 121, the generator power module 122 and the boosting power module 211 generate more heat when working again, by the arrangement mode, a better heat dissipation effect can be realized on the motor power module, the generator power module 122 and the boosting power module 211 through the cooling liquid channel 14.
The first installation position 131 and the second installation position 132 are disposed opposite to each other on two sides of the cooling liquid channel 14, that is, the first installation position 131 and the second installation position 132 are respectively disposed on two sides of the cooling liquid channel 14, and the first installation position 131 and the second installation position 132 are disposed opposite to each other. Wherein the second mounting location 132 may be disposed adjacent to the coolant channel 14. Through this kind of arrangement for the interval is less between first installation position 131 and the second installation position 132, is convenient for the electric connection between the two, and all is nearer apart from the distance of cooling liquid way 14, can realize the heat dissipation to boost assembly 21 better.
