[0042] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0043] According to the first aspect of the present application, refer to Figures 1 to 11 The present application provides a fuse assembly. The fuse assembly includes a housing 1, an inductor 2 and a fuse element 3, wherein the housing 1 is formed with a mounting cavity 11, the inductor 2 is disposed in the mounting cavity 11, the fuse element 3 is disposed in the mounting cavity 11, and the fuse element 3 is electrically connected to the inductor 2.

[0044] It is understandable that the inductor 2 and the fuse unit are simultaneously installed in the installation cavity 11 of the housing 1, so that the inductor 2 and the fuse element 3 are integrated in the housing 1 of the fuse component, thereby improving the integration of the fuse component and reducing the space requirement of the fuse component.

[0045] It is understandable that the components of the fuse assembly in the related art are dispersedly installed, resulting in a large space required for the fuse assembly. In the present application, the inductor 2 and the fuse element 3 are simultaneously installed in the housing 1, which improves the integration of the fuse assembly and helps to reduce the space requirement of the fuse assembly.

[0046] In some examples, the fuse element 3 is, for example, a DC passive fuse.

[0047] In some examples, the inductor 2 is, for example, a power inductor 2 .

[0048] In some embodiments, see Figure 1 The number of the fuse elements 3 is at least two, and at least two of the fuse elements 3 are connected in parallel to the inductor 2 .

[0049] It is understandable that at least two fuse elements 3 are connected in parallel to the inductor 2. When one of the fuse elements 3 fails and disconnects, the inductor 2 can still form a conductive path with the other fuse element 3, ensuring that the fuse component can still work normally.

[0050] It can be understood that when the fuse component is applied to the motor controller 10 of the vehicle, the present application provides at least two parallel fuse elements 3. When one of the fuse elements 3 fails and disconnects, there is still another fuse element 3 that can be connected to the inductor 2, ensuring that the vehicle can continue to drive without breaking down.

[0051] In some embodiments, see Figure 1 The insurance component also includes a first copper bar 4 , a first end of the first copper bar 4 is electrically connected to the inductor 2 , and a second end of the first copper bar 4 protrudes from the housing 1 .

[0052] It can be understood that the second end of the first copper bar 4 protrudes from the shell 1, thereby facilitating the electrical connection between the second end of the first copper bar 4 and other electronic components (such as the filter 61 of the motor controller 10), and the first end of the first copper bar 4 is electrically connected to the inductor 2, thereby facilitating the electrical connection between the inductor 2 and other electronic components.

[0053] It can be understood that integrating the first copper busbar 4 into the fuse component improves the integration of the fuse component.

[0054] It is understandable that the copper busbar is directly integrated into the insurance component, eliminating the separate copper busbar connection structure, which is conducive to reducing the number of parts developed and produced. When the insurance component is applied to the motor controller 10, the number of parts of the motor controller 10 can be effectively reduced, which is conducive to improving production efficiency.

[0055] In some embodiments, the housing 1 is formed with a first connection hole, and the second end of the first copper busbar 4 is passed through the first connection hole.

[0056] It can be understood that the first copper bar 4 is inserted into the first connection hole, and the housing 1 can limit the first copper bar 4, thereby improving the installation stability of the first copper bar 4.

[0057] It is understandable that the housing 1 is generally made of insulating material, and the first copper bus 4 is inserted into the housing 1 to effectively solve the safety problem.

[0058] In some examples, the housing 1 is, for example, an injection-molded part, and the first copper bar 4 is overmolded in the injection-molded part, thereby effectively solving the safety problem.

[0059] In some embodiments, see Figure 1 The insurance component further includes a second copper bar 5 , a first end of the second copper bar 5 is electrically connected to the insurance element 3 , and a second end of the second copper bar 5 protrudes from the housing 1 .

[0060] It can be understood that the second end of the second copper bar 5 protrudes from the shell 1, thereby facilitating the electrical connection between the second end of the second copper bar 5 and other electronic components (such as the capacitor 62 of the motor controller 10), and the first end of the second copper bar 5 is electrically connected to the fuse element 3, thereby facilitating the electrical connection between the fuse element 3 and other electronic components.

[0061] It can be understood that integrating the second copper busbar 5 into the fuse component improves the integration of the fuse component.

[0062] It is understandable that the copper busbar is directly integrated into the insurance component, eliminating the separate copper busbar connection structure, which is conducive to reducing the number of parts developed and produced. When the insurance component is applied to the motor controller 10, the number of parts of the motor controller 10 can be effectively reduced, which is conducive to improving production efficiency.

[0063] In some embodiments, the housing 1 is formed with a second connection hole, and the second end of the second copper busbar 5 is passed through the second connection hole.

[0064] It can be understood that the second copper bar 5 is inserted into the second connection hole, and the housing 1 can limit the second copper bar 5, thereby improving the installation stability of the second copper bar 5.

[0065] It is understandable that the housing 1 is generally made of insulating material, and the second copper busbar 5 is inserted into the housing 1 to effectively solve the safety problem.

[0066] In some examples, the housing 1 is, for example, an injection-molded part, and the second copper busbar 5 is overmolded in the injection-molded part, thereby effectively solving the safety problem.

[0067] According to the second aspect of the present application, refer to Figure 2 , Figure 3 and Fig.10 The present application provides a motor controller 10, comprising the above-mentioned insurance component.

[0068] It can be understood that the inductor 2 and the fuse unit are installed in the installation cavity 11 of the shell 1 at the same time, so that the inductor 2 and the fuse element 3 are integrated in the shell 1 of the fuse component, thereby improving the integration of the fuse component, reducing the space requirement of the fuse component, and facilitating the miniaturization design of the motor controller 10.

[0069] It is understandable that the insurance component mainly has the function of suppressing the charging and discharging of parallel capacitors due to different voltages, and has the function of timely cutting off the circuit when the current in the motor controller 10 is abnormally too large.

[0070] In some embodiments, see Figure 2 , Figure 3 and Fig.10The motor controller 10 includes a controller body 6 and a refrigeration component 7 . The controller body 6 includes the insurance component. The controller body 6 is installed on the refrigeration component 7 .

[0071] It is understandable that the controller body 6 is directly mounted on the refrigeration component 7 , and the refrigeration component 7 can cool the controller body 6 such as the fuse component.

[0072] It can be understood that the present application utilizes the refrigeration component 7 as the mounting base of the controller body 6, and realizes the reuse of the refrigeration component 7 while cooling the controller body 6, which is beneficial to reducing the volume of the motor controller 10, thereby reducing the installation space of the motor controller 10, reducing the overall quality of the motor controller 10, and reducing the cost.

[0073] It is understandable that the present application cancels the concept of the box in the related art, and only uses the refrigeration part 7 as a mounting seat to install the controller body 6, that is, the motor controller 10 of the present application does not have structures such as the box side wall and the top cover, which simplifies the structure of the motor controller 10 and helps to reduce the installation space of the motor controller 10. In addition, the controller body 6 is directly installed on the refrigeration part 7, without the obstruction of the box side wall and the box top cover in the related art, so that during production, the production equipment (such as a manipulator) has a larger activity space, which helps to reduce the difficulty of production and improve production efficiency.

[0074] In some examples, the refrigeration element 7 is a water cooling plate.

[0075] In some embodiments, see Figure 2 , Figure 3 , Figure 4 and Fig. 9 The controller body 6 further includes a filter 61, which is mounted on the refrigeration component 7. The filter 61, the inductor 2 and the insurance element 3 are electrically connected in sequence.

[0076] It is understandable that the filter 61 required by the motor controller 10 is installed on the cooling element 7 so that the cooling element 7 can cool the filter 61 , while improving the component integration of the motor controller 10 , which is beneficial to reducing the installation space of the motor controller 10 .

[0077] In some examples, the filter 61 is, for example, a DC bus filter.

[0078] In some embodiments, see Figure 3 , Figure 5 and Figure 6 The controller body 6 further includes a capacitor 62, which is mounted on the refrigeration component 7, and the inductor 2, the fuse element 3 and the capacitor 62 are electrically connected in sequence.

[0079] It is understandable that the capacitor 62 required by the motor controller 10 is installed on the cooling element 7 so that the cooling element 7 can cool the capacitor 62 , while improving the component integration of the motor controller 10 , which is beneficial to reducing the installation space of the motor controller 10 .

[0080] According to a third aspect of the present application, the present application provides a motor, comprising the above-mentioned motor controller 10.

[0081] It can be understood that the inductor 2 and the fuse unit are installed in the installation cavity 11 of the shell 1 at the same time, so that the inductor 2 and the fuse element 3 are integrated in the shell 1 of the fuse component, thereby improving the integration of the fuse component and reducing the space requirement of the fuse component, which is beneficial to the miniaturized design of the motor controller 10 and the miniaturized design of the motor.

[0082] In some embodiments, see Fig.10 and Fig.11 The motor includes a motor housing 8 , the motor housing 8 is formed with a receiving cavity 81 , and the motor controller 10 is installed in the receiving cavity 81 .

[0083] It is understandable that the integration of the motor and the electric control is achieved by installing the motor controller 10 in the motor housing 81. At the same time, since the motor controller 10 is installed in the motor housing 8, the motor controller 10 does not need to be sealed, reducing design restrictions.

[0084] In some embodiments, the motor controller is placed in the motor housing as a whole. When installing, the motor controller is placed into the motor from top to bottom. There are water channel ports and three-phase copper bus adapters inside the motor to position the motor controller as a whole. After the motor controller is installed, the DC bus is connected to the motor controller through the opening on the side wall of the motor, and the low-voltage connector needs to be assembled on the motor housing before the motor controller is installed. After the motor controller is installed, it is connected to the jack on the motor controller adapter board.

[0085] In some embodiments, the filter includes an integrated DC bus negative copper bus 901, a DC bus positive copper bus 902, a Y capacitor 903, a nanocrystalline magnetic ring 904, an X capacitor 905, and a ferrite magnetic ring 906, wherein the magnetic ring is used to eliminate high-frequency interference on the DC side, the Y capacitor 903 is used to suppress common-mode interference, and the X capacitor 905 is used to suppress differential-mode interference. Therefore, in order to meet the EMC requirements of the SiC controller or higher-level EMC requirements, a first-level ferrite magnetic ring 906, a first-level nanocrystalline magnetic ring 904 + a plurality of X and Y capacitors 903 are integrated to form a two-stage filter, which meets the EMC requirements; reduces costs, reduces assembly time, and facilitates automated production.

[0086] In some embodiments, the capacitor includes a high-voltage sampling harness 908 fixing base 907, a high-voltage sampling harness 908, a laser-welded positive copper busbar 909 on the capacitor IGBT side, a bracket 910, a laser-welded negative copper busbar 911 on the capacitor IGBT side, a laser-welded positive copper busbar 912 on the capacitor DC side, and a laser-welded negative copper busbar 913 on the capacitor DC side.

[0087] Driving motor function: The positive and negative currents of the DC busbar are respectively input into the capacitor through the laser-welded positive copper busbar 912 on the DC side of the capacitor and the laser-welded negative copper busbar 913 on the DC side of the capacitor, and then pass through the two small capacitors inside the capacitor shell, and then are output to the module 914 to drive the motor through the laser-welded positive copper busbar 909 on the IGBT side of the capacitor and the laser-welded negative copper busbar 911 on the IGBT side of the capacitor.

[0088] See also Figure 6 and Figure 7 When the capacitor is manufactured, the laser-welded copper bar at the capacitor end will be positioned through the positioning hole of the capacitor baffle to ensure that the position of the laser-welded copper bar of the capacitor product will not be offset. Before welding, the module 914 will be fixed on the box or tooling, and then the capacitor will be assembled. The positive copper bar of the capacitor will be connected to the positive copper bar of the module 914 after the capacitor is installed and fixed. Welding can begin after passing the pre-welding gap detection. After the positive copper bar is welded, the laser-welded lap copper bar can be placed on the negative copper bar of the capacitor and the negative copper bar of the module 914.

[0089] The overlapped copper bars are positioned through the positioning holes. Because the copper bars are long, two pre-welding detection holes are added inside the copper bars to facilitate the gap detection between the two laser-welded copper bars. Welding can be carried out after the detection is completed. At the same time, considering the safety requirements and welding requirements, high-temperature resistant insulation materials are added to the inside of the copper bars for protection.

[0090] In some embodiments, see Figure 8 The three-phase injection molded part includes a three-phase injection molded part housing 915, a three-phase copper busbar 916, a three-phase magnetic ring glue filling surface 917, a three-phase injection molded part mounting foot 918 and a magnetic ring. The shape is flat, which reduces the Z-direction height of the three-phase copper busbar 916 component and reduces the space occupied by the motor controller box in the Z direction, making its structure more compact. The addition of a magnetic ring on the three-phase side makes the controller EMC effect better. The magnetic ring and the three-phase copper busbar 916 are integrally molded in the injection molded part to save the internal space of the motor controller. During the production process, the three-phase output part can be installed in one step, which can meet the needs of the automated assembly line.

[0091] When producing the motor controller, the IGBT module and the capacitor are first laser welded together and placed in the motor controller box. The three-phase copper busbar assembly is pre-installed in the Hall assembly, and the pre-installed Hall and three-phase copper busbar assembly are installed at the output end of the IGBT module; then the driver board, control board shielding board and control board are installed in sequence; then the entire controller is turned 180 degrees to install the back part, the inductor fuse holder is first installed on the water cooling plate, and then the two DC passive fuses are installed on the inductor fuse holder, and finally the DC filter is installed on the water cooling plate, and all parts are installed. Finally, the copper busbar overlap is welded by laser welding, and the entire controller is installed.

[0092] In this application, except for the use of bolts to fix all parts and components to the water-cooled plate, the rest of the copper busbar overlap parts all use laser welding to cancel the copper busbar connection. The advantage is that the area of ​​the copper busbar overlap is larger than that of the bolting solution, which has better overcurrent capability, reduces the heating of the copper busbar, and improves the overcurrent efficiency. At the same time, all laser welding surfaces are designed to be as high as possible. During production, the laser welding equipment can complete the laser welding work of one side of the controller at one time, which greatly improves the production efficiency. Compared with the bolting solution, the production cycle of grabbing and replacing bolts is faster. The laser welding process is also used for the overlap between the capacitor and the IGBT, which reduces the stray inductance and increases the overcurrent efficiency.

[0093] In this application, the motor controller is reasonably laid out, with only one wiring harness connected to the motor, and no wiring harness is used in other locations. By reducing the wiring harness design, the controller is made neater and more beautiful, and the risk of failure caused by loose wiring harness connection is reduced. This solution is to design the motor controller inside the motor housing, realize the integration of the motor and the motor controller, and move the installation position of connectors such as the DC bus and low-voltage connectors to the motor housing, saving space; at the same time, since the motor controller box is installed in the motor housing, there is no need to seal the motor controller, reducing design restrictions. The water channel of this solution can cool the IGBT and inductor at the same time, realize the efficient use of the water channel, and fully dissipate heat from the components. This solution is compatible with both front-wheel drive and rear-wheel drive motors, and can be adapted by simply replacing the filter. There is no need to develop separate motor controllers for the front and rear drives, which greatly saves costs.

[0094] According to a fourth aspect of the present application, the present application provides a vehicle, comprising the above-mentioned motor.

[0095] It can be understood that the inductor 2 and the fuse unit are installed in the installation cavity 11 of the shell 1 at the same time, so that the inductor 2 and the fuse element 3 are integrated in the shell 1 of the fuse component, thereby improving the integration of the fuse component and reducing the space requirement of the fuse component, which is beneficial to the miniaturized design of the motor controller 10 and the miniaturized design of the motor.

[0096] In some examples, the vehicle may be a fuel vehicle, a plug-in hybrid vehicle, or a new energy vehicle, etc., and this application does not make specific limitations on this.
