These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed Description of the Embodiment

[0055] A power circuit board is usually included in a motor controller, which can invert direct current into alternating current to achieve control of the motor speed and torque.

[0056] In a high-power motor controller, the current is usually large, often reaching hundreds of amperes, and small-current power devices can no longer meet the requirements. Therefore, a power device module is often selected, and the power device module contains multiple small-current power devices connected in parallel.

[0057] In the related art, the power device module needs to be welded and installed on the circuit board. During the reflow soldering process, the solder may lose its shape or position due to overheating, resulting in poor stability of the power device module.

[0058] As Figures 1 to 3 shown, an embodiment of the present application provides a motor controller, including: a body 1, a bracket 2, and a plurality of discrete devices 3. Among them, the bracket 2 is arranged on the body 1, and the bracket 2 is formed with a first abutting portion 21; the discrete device 3 is arranged on the bracket 2, the discrete device 3 is formed with a second abutting portion 31, and the first abutting portion 21 and the second abutting portion 31 are connected; in the height direction of the body 1, the body 1 and the discrete device 3 are arranged at intervals, and the discrete device 3, the bracket 2, and the body 1 jointly enclose a receiving cavity for receiving solder.

[0059] It should be noted that the first abutting portion 21 is used to abut against the second abutting portion 31 to support the discrete device 3. When the first abutting portion 21 abuts against the second abutting portion 31, the body 1 and the discrete device 3 are arranged at intervals, and in the height direction of the body 1, the discrete device 3 is located above the body 1.

[0060] It should be noted that the interval between the body 1 and the discrete device 3 and the bracket 2 enclose a receiving cavity, and the solder is arranged inside the receiving cavity.

[0061] It can be understood that the receiving cavity can limit the flow of the solder, and the bracket 2 can limit the offset of the discrete device 3. During the reflow soldering process, after the solder is overheated and melted and is in a liquid state, the liquid solder flows in the receiving cavity, and the liquid solder is respectively connected to the body 1 and the discrete device 3. After the liquid solder solidifies, it may solidify between the body 1 and the discrete device 3 to improve the connection stability between the body 1 and the discrete device 3.

[0062] Therefore, the embodiments of the present application can solve the problem of poor stability of the power device module during the reflow soldering process.

[0063] The embodiment of the present application provides a body 1 that is formed with a first mounting portion and a second mounting portion; the bracket 2 is arranged on the first mounting portion; in the height direction of the body 1, the discrete device 3 is located above the second mounting portion; the first mounting portion and the second mounting portion are arranged at intervals.

[0066] In another feasible implementation manner, the first mounting portion is disposed on the body 1 , and the plane where the first mounting portion is located is coplanar with the plane where the body 1 is located.

[0067] In addition, in another feasible implementation manner, the first mounting portion is disposed lower than the main body 1 , that is, the first mounting portion is a first recessed portion, and the first mounting portion is extended toward a side away from the bracket 2 .

[0068] It is understandable that there is no limitation on the specific arrangement of the first mounting portion, and it can be selected according to actual use requirements, and it is only necessary to ensure that the bracket 2 is arranged on the first mounting portion.

[0069] It should be noted that the second mounting portion has a variety of different configurations, and the configurations of the second mounting portion are described below in turn with examples.

[0070] In a feasible implementation manner, the second mounting portion protrudes from the main body 1 , the second mounting portion extends toward a side close to the bracket 2 , and at least partially protrudes from the surface of the main body 1 .

[0071] In another feasible implementation manner, the second mounting portion is disposed on the body 1 , and the plane where the second mounting portion is located is coplanar with the plane where the body 1 is located.

[0072] In addition, in another feasible implementation manner, the second mounting portion is disposed lower than the main body 1 , that is, the second mounting portion is a second recessed portion, and the second mounting portion is extended toward a side away from the bracket 2 .

[0073] It is understandable that there is no limitation on the specific arrangement of the second mounting portion, and it can be selected according to actual use requirements, as long as the discrete device 3 is arranged above the second mounting portion.

[0074] One end of the solder provided in the embodiment of the present application is connected to the second mounting portion, and the other end of the solder is connected to the discrete device 3 .

[0075] It can be understood that the solder is used to connect the discrete device 3 and the body 1 to limit the movement of the discrete device 3 relative to the body 1 .

[0076] The first mounting portion provided in the embodiment of the present application is a first annular portion, and the second mounting portion is a second annular portion. The first annular portion and the second annular portion are concentrically arranged, and the first annular portion is arranged on the side of the outer ring of the second annular portion away from the symmetry center of the second annular portion.

[0077] It should be noted that the first annular portion and the second annular portion have a variety of different configurations. The configurations of the first annular portion and the second annular portion are described below with examples.

[0078] In a feasible embodiment, the first annular portion is a first square ring, and the second annular portion is a second square ring. In the projection in the height direction of the main body 1, the area of ​​the first square ring is greater than the area of ​​the second square ring, and the first square ring is arranged around the outer ring of the second square ring, that is, the first square ring is arranged on the side of the outer ring of the second square ring away from the symmetry center of the second square ring.

[0080] It is understandable that there is no restriction on the specific configuration shapes of the first annular portion and the second annular portion, and they can be selected according to actual use requirements, as long as the first annular portion is arranged on the side of the outer circle of the second annular portion away from the symmetry center of the second annular portion.

[0081] It is understandable that the second annular portion is arranged inside the first annular portion, that is, the first annular portion extends around the outer ring of the second annular portion toward a side away from the symmetry center of the second annular portion, so that the discrete device 3 can be supported and installed on the bracket 2. Thus, the bracket 2 can protect the discrete device 3.

[0082] The bracket 2 provided in the embodiment of the present application includes a first wall 22, a second wall 23, a third wall 24 and a fourth wall 25 which are fixedly connected in sequence, the first wall 22 and the third wall 24 are arranged opposite to each other, and the second wall 23 and the fourth wall 25 are arranged opposite to each other; the first wall 22, the second wall 23, the third wall 24 and the fourth wall 25 are jointly enclosed to form a square cavity; the discrete device 3 is arranged in the square cavity.

[0083] It can be understood that both the discrete device 3 and the solder are disposed within the square cavity. The first wall surface 22, the second wall surface 23, the third wall surface 24, and the fourth wall surface 25 can respectively provide safety protection for the discrete device 3. The square cavity can limit the flow of the solder to provide safety protection for the motor controller, and can also reduce the soldering difficulty between the discrete device 3 and the body 1, thereby improving the soldering speed of the discrete device 3.

[0084] In the embodiment provided by the present application, the discrete device 3 is formed with a first side wall 32, a second side wall 33, a third side wall 34, and a fourth side wall 35 that are connected in sequence. The first side wall 32 and the third side wall 34 are disposed opposite to each other, and the second side wall 33 and the fourth side wall 35 are disposed opposite to each other; in the height direction perpendicular to the body 1, the first wall surface 22 and the first side wall 32 are spaced apart, the second wall surface 23 and the second side wall 33 are spaced apart, the third wall surface 24 and the third side wall 34 are spaced apart, and the fourth wall surface 25 and the fourth side wall 35 are spaced apart.

[0085] It can be understood that the first wall surface 22 is used to limit the movement of the first side wall 32 towards the side close to the first wall surface 22; the second wall surface 23 is used to limit the movement of the second side wall 33 towards the side close to the second wall surface 23; the third wall surface 24 is used to limit the movement of the third side wall 34 towards the side close to the third wall surface 24; the fourth side wall 35 is used to limit the movement of the fourth side wall 35 towards the side close to the fourth wall surface 25.

[0086] In the motor controller provided by the embodiment of the present application, in the height direction of the body 1, the first wall surface 22 is disposed higher than the first side wall 32; the second wall surface 23 is disposed lower than the second side wall 33; the third wall surface 24 is disposed higher than the third side wall 34; the fourth wall surface 25 is disposed lower than the fourth side wall 35.

[0087] It should be noted that the first wall surface 22 and the third wall surface 24 are used to protect the discrete device 3 and limit the offset of the discrete device 3 between the first wall surface 22 and the third wall surface 24.

[0088] It should be noted that the plane where the highest positions of the second wall surface 23 and the fourth wall surface 25 are located abuts against the discrete device 3 to support the discrete device 3. The second wall surface 23 and the fourth wall surface 25 can limit the offset of the discrete device 3 between the second wall surface 23 and the fourth wall surface 25.

[0089] It should be noted that the first wall surface 22 and the third wall surface 24 are parallel to each other, and the second wall surface 23 and the fourth wall surface 25 are parallel to each other.

[0092] It can be understood that the supporting part is used to accommodate the discrete device 3 to protect the discrete device 3, and the supporting part can guide the installation of the discrete device 3, thereby reducing the installation difficulty of the discrete device 3.

[0093] A motor controller usually includes a power circuit board, which can invert direct current into alternating current to realize the control of the motor speed and torque.

[0094] In a high-power motor controller, the current is usually large, often reaching hundreds of amperes, and small-current power devices can no longer meet the requirements. Therefore, a power device module is often selected, and the power device module contains a plurality of parallel small-current power devices.

[0095] The shape of the power device module is fixed, and the layout of the power module group on the power circuit board is limited, which is not conducive to reasonable layout and reducing the volume.

[0097] It can be understood that the upper-bridge discrete device 36 and the lower-bridge discrete device 37 of one discrete device 3 are arranged at intervals in the first direction X, which can reduce the installation space of one discrete device 3 on the main body; in the first direction X, two adjacent discrete devices 3 are arranged at intervals, which can shorten the connection distance between the lower-bridge discrete device 37 of the previous discrete device 3 and the upper-bridge discrete device 36 of the next discrete device 3, thereby increasing the power density on the main body per unit area.

[0098] It can be understood that the supporting part can guide the installation of the discrete device 3, thereby reducing the installation difficulty of the discrete device 3.
