Description

Technical Field

[0001] This utility model relates to the field of motor controller technology, specifically to a motor controller and a vehicle. Background Technology

[0002] With the rapid development of new energy vehicles, the electric control system, as the core component of its power control, has been widely used. The cover of the motor controller plays the role of enclosing and protecting the various components inside and outside the controller. However, in related technologies, the motor controller requires at least two positioning parts between the housing and the cover for pre-positioning. The number of parts is large, and the plug-in parts need to occupy the space inside the housing, resulting in a large housing volume. This makes it inconvenient to miniaturize the motor controller and causes waste of materials and costs. Utility Model Content

[0003] One objective of this utility model is to provide a motor controller to solve the problem that the existing technology has many positioning parts and that the plug-in parts occupy the space of the housing, resulting in a large housing volume. Another objective of this utility model is to provide a vehicle.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A motor controller includes: a housing having an opening and a mating surface forming around the opening, a protrusion formed on the mating surface, the protrusion protruding in a direction away from the mating surface; a cover plate connected to the mating surface and covering the opening, the cover plate having a recess on one side facing the housing, the protrusion being inserted into the recess; a circuit board disposed in the housing; and a connector connected to the side of the circuit board away from the housing, the connector being located outside the housing and within the recess, the connector passing through the protrusion.

[0006] Based on the above technical means, the cooperation of the convex and concave parts can, on the one hand, pre-position the relative position between the housing and the cover plate, which facilitates the subsequent installation between the cover plate and the housing and reduces the number of positioning parts. On the other hand, the concave part can accommodate the plug-in parts, which will not occupy the space of the housing. The layout of electrical components inside the housing is more compact. Moreover, the plug-in parts can be accommodated by the partial convex part of the cover plate, avoiding the overall increase of the space of the cover plate. This can reduce the installation space required for the motor controller, save production materials, and reduce costs.

[0007] Furthermore, the cover plate includes a plate body and an extension, the plate body and the extension are connected, the recess includes a first recess and a second recess, the first recess is disposed in the extension, the second recess is disposed in the plate body, and the first recess and the second recess are connected.

[0008] The above-mentioned technical means can increase the volume of the recess to accommodate the connector, and the cover plate only protrudes locally without causing an excessive increase in the volume of the cover plate, thus avoiding an excessive increase in the space and materials required for the cover plate arrangement.

[0009] Furthermore, the main body of the plate includes a base plate and a side plate. The base plate is provided with the second recess and is connected to the extension. The side plate is provided on the side of the base plate facing the housing and extends circumferentially along the base plate and is connected to the extension. The cover plate also includes a sealing edge, which is provided on the side plate and the extension and abuts against the mating surface and the protrusion.

[0010] According to the above technical means, a space can be formed between the side plate and the mating surface, as well as between the concave and convex parts. The space can be used to arrange the sealing element. The sealing edge can limit the sealing element, improve the sealing effect between the housing and the cover plate, give the motor controller good waterproof and dustproof performance, and the sealing structure is simple, which can reduce costs.

[0011] Furthermore, a portion of the sealing edge extends beyond the outer peripheral surface of the side plate.

[0012] The above-mentioned technical means can increase the contact area between the sealing edge and the box body, thereby improving the sealing effect.

[0013] Furthermore, the portion of the sealing edge extending beyond the outer periphery of the side plate is provided with a mounting hole; the motor controller also includes a conductive mounting component, which passes through the mounting hole and the mating surface and is fixed to the housing, and the housing and the cover plate are electrically connected through the conductive mounting component.

[0014] Based on the above technical means, not only can the relative position between the cover plate and the housing be fixed, but the cover plate and the housing can also be electrically connected. The cover plate and the housing together play an electromagnetic shielding role, thereby avoiding interference between the electrical components inside and outside the motor controller and improving the motor controller's ability to resist electromagnetic interference.

[0015] Furthermore, the portion of the sealing edge extending beyond the outer periphery of the side plate is provided with a positioning hole, the positioning hole being located on the side of the plate body away from the extension portion; the motor controller also includes a positioning element, the positioning element passing through the positioning hole and the mating surface and being fixed to the housing.

[0016] According to the above technical means, only one positioning component is needed to fix the opposite sides of the cover plate to the box body, which can improve the positioning reliability between the cover plate and the box body. While achieving the double-sided limiting effect of the cover plate, the number of parts is small, reducing costs.

[0017] Furthermore, the motor controller also includes a shielding rib, which is connected to the side of the cover plate facing the housing and extends circumferentially along the recess.

[0018] Based on the aforementioned technical means, the area where the connector is located can be separated from the area where other electrical components are located, reducing the impact of other electrical components on the connector and effectively preventing mutual interference between electrical components in different areas within the motor controller. Furthermore, the shielding ribs can improve the structural strength and modal characteristics of the cover plate, thereby improving the NVH (Noise, Vibration, Harshness) performance of the cover plate.

[0019] Furthermore, the shielding rib is spaced apart from the circuit board, and the shielding rib has a groove on the side facing the housing; the motor controller also includes a flexible conductive element, which is disposed in the groove and abuts against the circuit board.

[0020] Based on the above technical means, on the one hand, rigid contact between the shielding rib and the circuit board is avoided; on the other hand, the shielding rib and the circuit board are electrically connected through flexible conductive parts, which further reduces the influence of other electrical components on the connector and improves the reliability of signal transmission.

[0021] Furthermore, there are multiple grooves, which are spaced apart along the extending direction of the shielding rib, and each groove contains the flexible conductive element.

[0022] Based on the above technical means, on the one hand, the number of grooves and flexible conductive parts is increased, further reducing the gap between the shielding ribs and the circuit board. On the other hand, each flexible conductive part is small in size, which makes it easy to install and fix a single flexible conductive part. Moreover, the failure of all flexible conductive parts will not be caused by the detachment of one flexible conductive part, resulting in high fault tolerance efficiency.

[0023] Furthermore, both the groove and the flexible conductive element are single entities, and both extend along the extension direction of the shielding rib.

[0024] Based on the above technical means, the flexible conductive component can be set to be relatively long, and the flexible conductive component is a continuous structure, which can greatly reduce the gap between the shielding rib and the circuit board, and is more conducive to improving the electromagnetic shielding effect inside the motor controller.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0054] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0055] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0056] The following is combined Figures 1 to 7 The following describes embodiments of the present invention.

[0057] According to an embodiment of the present invention, a motor controller 1 is provided, which includes a housing 100, a cover plate 200, a circuit board 300, and a connector 400.

[0058] The housing 100 has an opening 110, and a mating surface 130 is formed around the opening 110. A protrusion 120 is formed on the mating surface 130, and the protrusion direction of the protrusion 120 is the same as the opening direction of the opening 110. The protrusion 120 protrudes away from the mating surface 130 and has a through hole 140. The cover plate 200 is connected to the mating surface 130 and covers the opening 110. The cover plate 200 has a recess 201 on the side facing the housing 100, and the protrusion 120 is inserted into the recess 201. The circuit board 300 is disposed on the housing 100. The connector 400 is connected to the side of the circuit board 300 facing the cover plate 200, that is, the connector 400 is connected to the side of the circuit board 300 facing away from the housing 100. The connector 400 is located outside the housing 100 and inside the recess 201. The connector 400 passes through the through hole 140, that is, the connector 400 passes through the protrusion 120.

[0059] The cover plate 200 can be integrally cast from aluminum alloy. On the plane perpendicular to the protrusion 120, the width of the projection of the extension 220 gradually decreases in the direction away from the housing 100. For example, the projection of the extension 220 can be arc-shaped, triangular, trapezoidal, etc.

[0060] By providing an opening 110 on the housing 100, various electrical components inside the motor controller 1 can be installed inside the housing 100 through the opening 110, and the circuit board 300 can also be installed inside the housing 100. Furthermore, during subsequent maintenance of the motor controller 1, the electrical components can also be removed from the housing 100 through the opening 110.

[0061] By setting the cover plate 200, the opening 110 of the housing 100 can be sealed, which reduces the probability of the electrical components inside the motor controller 1 being corroded by external dust and liquids, and also prevents the electrical components inside the motor controller 1 from being damaged by bumps, thereby improving the working performance and service life of the motor controller 1.

[0062] The connector 400 passes through the through hole 140, that is, the connector 400 is exposed from the housing 100 and the cover plate 200, which enables the motor controller 1 to connect with external electrical components so that the circuit board 300 can exchange signals with external electrical components. For example, the vehicle control unit (VCU) in the vehicle is connected to the connector 400 through wires to realize the signal exchange between the vehicle controller and the motor controller 1.

[0063] A protrusion 120 is provided on the housing 100, and a recess 201 is provided on the cover plate 200. The protrusion 120 and the recess 201 cooperate to pre-position the relative position between the housing 100 and the cover plate 200, which facilitates the subsequent installation between the cover plate 200 and the housing 100 and reduces the number of positioning parts. On the other hand, the recess 201 can accommodate the plug-in component 400. The side of the cover plate 200 facing away from the housing 100 where the recess 201 is located can have the protrusion 120 to ensure the thickness of the cover plate 200. The plug-in component 400 will not occupy the space of the housing 100. The layout of electrical components inside the housing 100 is more compact. Moreover, the plug-in component 400 can be accommodated by the partial protrusion of the cover plate 200, avoiding an increase in the overall space of the cover plate 200. This can reduce the installation space required for the motor controller 1, save production materials, and reduce costs.

[0064] Furthermore, such as Figure 7 As shown, the cover plate 200 includes a plate body 210 and an extension 220. The side of the plate body 210 is connected to the extension 220. The recess 201 includes a first recess 202 and a second recess 203. The first recess 202 is located in the extension 220, and the second recess 203 is located in the plate body 210. The first recess 202 and the second recess 203 are connected.

[0065] For example, on a plane perpendicular to the cover plate 200, the width of the projection of the extension 220 gradually decreases in the direction away from the plate body 210. For example, the projection of the extension 220 can be an arc, a triangle, a trapezoid, etc.

[0066] By providing the extension 220, the volume of the recess 201 can be increased to accommodate the connector 400, and the cover plate 200 only protrudes partially, without causing an excessive increase in the volume of the cover plate 200, thus avoiding an excessive increase in the space and materials required for the arrangement of the cover plate 200.

[0067] Furthermore, such as Figure 3 , Figure 4 and Figure 7 As shown, the main body 210 includes a base plate 211 and a side plate 212. The base plate 211 has a second recess 203. The side plate 212 is located on the side of the base plate 211 facing the housing 100. An extension 220 is connected to the base plate 211. The side plate 212 extends circumferentially along the base plate 211 and is connected to the extension 220. That is, the side plate 212 and the extension 220 are arranged and connected circumferentially along the base plate 211. The cover plate 200 also includes a sealing edge 230. The sealing edge 230 is located on the side of the side plate 212 facing the housing 100 and on the side of the extension 220 facing the housing 100. The sealing edge 230 abuts against the side of the housing 100 facing the cover plate 200. Specifically, the sealing edge 230 abuts against the mating surface 130 and the protrusion 120.

[0068] By abutting the sealing edge 230 against the housing 100, a space can be formed between the side plate 212 and the mating surface 130, as well as between the recess 201 and the protrusion 120. The aforementioned spaces can be used to arrange the sealing element 600. The sealing edge 230 can limit the sealing element 600. The height of the sealing edge 230 can be adjusted according to the material characteristics of the sealing element 600 and the sealing pressure value, thereby improving the sealing effect between the housing 100 and the cover plate 200, giving the motor controller 1 good waterproof and dustproof performance, and the sealing structure is simple, which can reduce costs.

[0069] The sealing element 600 can be a structure such as sealant or foam. The sealing element 600 can be conductive to make an electrical connection between the cover plate 200 and the housing 100. At least one of the housing 100 and the cover plate 200 is grounded. The cover plate 200 and the housing 100 together play an electromagnetic shielding role, thereby avoiding interference between electrical components inside and outside the motor controller 1 and optimizing the working stability of the motor controller 1.

[0070] In some embodiments, such as Figure 7 As shown, a portion of the sealing edge 230 extends beyond the outer periphery of the side plate 212. This increases the contact area between the sealing edge 230 and the housing 100, improving the sealing effect.

[0071] Furthermore, the portion of the sealing edge 230 extending beyond the outer periphery of the side plate 212 is provided with a mounting hole 214. The motor controller 1 also includes a conductive mounting component, which passes through the mounting hole 214 and the mating surface 130, and is fixed to the housing 100. The housing 100 and the cover plate 200 are electrically connected through the conductive mounting component. The conductive mounting component can be a threaded fastener, such as a screw or nut.

[0072] By setting conductive mounting components, not only can the relative positions between the cover plate 200 and the housing 100 be fixed, but the electrical connection between the cover plate 200 and the housing 100 can also be improved. Furthermore, at least one of the housing 100 and the cover plate 200 can be grounded, and the cover plate 200 and the housing 100 can play an electromagnetic shielding role. This will prevent the electrical components inside and outside the motor controller 1 from interfering with each other, improve the anti-electromagnetic interference capability of the motor controller 1, and optimize the working stability of the motor controller 1.

[0073] Furthermore, such as Figure 7 As shown, the portion of the sealing edge 230 extending beyond the outer periphery of the side plate 212 is provided with a positioning hole 213, which is located on the side of the main body away from the extension 220. The motor controller 1 also includes a positioning element, which passes through the positioning hole 213 and the mating surface 130, and is fixed to the housing 100. The positioning element can be a pin.

[0074] Because the protrusion 120 and the recess 201 cooperate to position one side of the cover plate 200 and the box body 100, and then the other side of the cover plate 200 and the box body 100 are positioned by the positioning component, only one positioning component is needed to fix the opposite sides of the cover plate 200 to the box body 100. This can improve the positioning reliability between the cover plate 200 and the box body 100. While achieving the double-sided limiting effect of the cover plate 200, it reduces the number of machining of the positioning holes 213 and the number of positioning components used. The number of parts is small, which reduces the cost.

[0075] Furthermore, such as Figures 3-5 As shown, a first inclined wall 240 is formed on the side of the second recess 203 facing away from the housing 100 in the substrate 211. The distance between the first inclined wall 240 and the circuit board 300 gradually increases towards the first recess 202. A flat wall 250 and a second inclined wall 260 are formed on the side of the first recess 202 facing away from the housing 100 in the extension 220. The second inclined wall 260 is located on opposite sides of the flat wall 250 in the length direction and is connected to the sealing edge 230. The distance between the second inclined wall 260 and the circuit board 300 gradually increases towards the flat wall 250. The flat wall 250 is connected to the first inclined wall 240.

[0076] In this way, while ensuring sufficient space for the insertion piece 400, the transition between different areas of the recess 201 is relatively smooth, which can reduce the probability of local stress concentration.

[0077] In some embodiments, such as Figure 2 , Figures 5-7 As shown, the motor controller 1 also includes a shielding rib 500, which is connected to the cover plate 200 on the side facing the housing 100, and the shielding rib 500 extends circumferentially along the recess 201. The shielding rib 500 and the cover plate 200 can be integrally formed, for example, the shielding rib 500 and the cover plate 200 are integrally cast from aluminum alloy.

[0078] It should be noted that, in addition to the circuit board 300 and the connector 400, the enclosure 100 also contains other electrical components, such as IGBT modules, capacitors, and conductive copper busbars. These electrical components may generate electromagnetic interference with the connector 400, affecting the reliability of signal transmission.

[0079] By setting the shielding rib 500, the area where the connector 400 is located can be separated from the area where other electrical components are located, reducing the influence of other electrical components on the connector 400, effectively avoiding mutual interference between electrical components in different areas inside the motor controller 1, and improving the reliability of signal transmission. Furthermore, the shielding rib 500 can improve the structural strength and modal characteristics of the cover plate 200, thereby improving the NVH (Noise, Vibration, Harshness) performance of the cover plate 200.

[0080] Among them, a reinforcing rib 270 is provided on the side of the cover plate 200 facing the housing 100. The reinforcing rib 270 is located on the side of the shielding rib 500 facing away from the recess 201. Through the cooperation of the reinforcing rib 270 and the shielding rib 500, the structural strength and modal characteristics of the cover plate 200 can be further improved, and the NVH performance of the cover plate 200 can be further improved.

[0081] Furthermore, such as Figure 2 , Figures 5-7 As shown, the shielding rib 500 is spaced apart from the circuit board 300, and the shielding rib 500 has a groove 510 on the side facing the housing 100. The motor controller 1 also includes a flexible conductive element 520, which is disposed in the groove 510 and abuts against the circuit board 300. The flexible conductive element 520 can be conductive adhesive or conductive foam. The circuit board 300 can be grounded.

[0082] In this way, on the one hand, rigid contact between the shielding rib 500 and the circuit board 300 is avoided, reducing the probability of the shielding rib 500 damaging the circuit board 300. Furthermore, the shielding rib 500 indirectly presses the circuit board 300 through the flexible conductive element 520, which can also improve the positional stability of the circuit board 300 to a certain extent. On the other hand, the shielding rib 500 and the circuit board 300 are electrically connected through the flexible conductive element 520. The flexible conductive element 520 can deform to seal the gap between the shielding rib 500 and the circuit board 300, further reducing the impact of other electrical components on the connector 400 and improving the reliability of signal transmission.

[0083] Specifically, in some embodiments, there are multiple grooves 510, which are spaced apart along the extending direction of the shielding rib 500. Each groove 510 is provided with a flexible conductive element 520. In this way, on the one hand, the number of grooves 510 and flexible conductive elements 520 is increased, further reducing the gap between the shielding rib 500 and the circuit board 300, which can improve the electromagnetic shielding effect. On the other hand, each flexible conductive element 520 is small in size, which makes it easy to install and fix a single flexible conductive element 520, and the failure of all flexible conductive elements 520 due to the detachment of one flexible conductive element 520 will not occur, resulting in high fault tolerance efficiency.

[0084] In other embodiments, there is only one groove 510 and one flexible conductive element 520, and both the groove 510 and the flexible conductive element 520 extend along the extending direction of the shielding rib 500. In this way, the flexible conductive element 520 can be set to be relatively long, and since the flexible conductive element 520 is a connecting structure, it can greatly reduce the gap between the shielding rib 500 and the circuit board 300, which is more conducive to improving the electromagnetic shielding effect.
