Description

Technical Field

[0001] The utility model generally relates to the technical field of motors, and more specifically to an electric control device, a motor and a vehicle. Background Art

[0002] In the prior art, the electric control device of a motor is usually arranged outside the motor housing, resulting in poor integration and a relatively large overall volume of the motor.

[0003] Therefore, the prior art also provides an integrated electric control motor. By installing the circuit board of the controller in the installation cavity of the rear cover and reasonably utilizing the space inside the rear cover, the controller is integrated into the entire motor. The controller does not need to be arranged outside the motor housing to occupy space, thereby effectively improving the integration of the motor and effectively reducing the overall volume of the motor.

[0004] However, this technical solution still has some deficiencies: Resin is filled in the installation cavity of the rear cover to fix the circuit board, and the heat dissipation problem of the circuit board is not considered. When the temperature of the circuit board rises relatively high during the operation of the motor, the heat dissipation effect cannot meet the requirements, which easily leads to motor shutdown or even damage to the circuit board.

[0062] In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present utility model, some well-known technical features in the art are not described.

[0063] To thoroughly understand the present utility model, a detailed description will be presented in the following. It should be understood that these embodiments are provided to make the disclosure of the present utility model thorough and complete, and to fully convey the concept of these exemplary embodiments to those of ordinary skill in the art. Obviously, the implementation of the embodiments of the present utility model is not limited to the special details familiar to those skilled in the art. The preferred embodiments of the present utility model are described in detail below. However, in addition to these detailed descriptions, the present utility model may also have other embodiments.

[0064] The ordinal numbers such as "first" and "second" cited in the present utility model are merely identifiers and do not have any other meanings, such as a specific order, etc. Moreover, for example, the term "first component" itself does not imply the existence of a "second component", and the term "second component" itself does not imply the existence of a "first component".

[0065] It should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer" and similar expressions used in the present utility model are only for illustrative purposes and are not restrictive.

[0066] In some application scenarios, in order to dissipate heat from the electronic control board inside the electronic control box, some covers are provided with a heat-conducting layer with a relatively large area on the side close to the electronic control board. The heat-conducting layer only includes an integral heat dissipation area, and the integral heat dissipation area corresponds to all the electronic devices on the electronic control board. The electronic devices can contact the integral heat dissipation area for heat conduction, but it does not distinguish which electronic devices generate more heat and which generate less heat, nor does it avoid the positions of the gaps between the electronic devices. Such a solution can dissipate heat for the electronic devices, but obviously also causes waste of the heat-conducting layer material.

[0067] The present utility model discloses an electronic control device, a motor and a vehicle.

[0068] Now, exemplary embodiments according to the present utility model will be described in more detail with reference to the accompanying drawings.

[0069] As Figure 1 、 Figure 2 、 Figure 3 shown, in a preferred embodiment, an electronic control device 100 includes: an electronic control board 2 and an electronic control box;

[0070] Electronic devices are provided on the electronic control board 2; the electronic control board 2 can be a circuit board of a certain control device, and the electronic devices are various electronic components arranged according to the designed control circuit; the electronic control board 2 is adapted to be arranged inside the electronic control box.

[0071] The electric control box includes a box body 3 and a cover plate 1; the box body 3 and the cover plate 1 can form a closed installation space to accommodate the electric control board 2, forming an isolation protection for the electric control board 2;

[0072] A first heat-conducting layer is provided on one side of the cover plate 1 close to the electric control board 2, and the first heat-conducting layer includes a plurality of heat-dissipating areas; and / or a second heat-conducting layer is provided on one side of the box body 3 close to the electric control board 2, and the second heat-conducting layer includes a plurality of heat-dissipating areas;

[0073] The heat dissipation area is arranged corresponding to the electronic device, and the electronic device can contact the heat dissipation area for heat conduction, and finally dissipate heat through the cover plate 1 and / or the box body 3 .

[0074] According to the heat dissipation requirements, a heat-conducting layer (correspondingly having multiple heat-dissipating zones) may be provided only on the cover plate 1 to dissipate heat only for the electronic devices on the first surface 22 of the electric control board 2; a heat-conducting layer (correspondingly having multiple heat-dissipating zones) may be provided only on the box body 3 to dissipate heat only for the electronic devices on the second surface 23 of the electric control board 2; or a heat-conducting layer (correspondingly having multiple heat-dissipating zones) may be provided on both the cover plate 1 and the box body 3 to dissipate heat for the electronic devices on both the first surface 22 and the second surface 23 of the electric control board 2.

[0075] The thermal conductive layer in the present application includes multiple heat dissipation zones, namely separate heat dissipation zones, rather than integrated heat dissipation zones. Multiple heat dissipation zones are convenient for making corresponding designs according to different electronic devices, and are also convenient for avoiding gaps between electronic devices. The material used for the thermal conductive layer is specifically coated on the corresponding electronic device rather than being coated on a large area without distinction, thereby saving thermal conductive materials, reducing manufacturing costs, and facilitating the disassembly of the electronic control board during repair and maintenance.

[0076] The heat-conducting layer and the electronic device are in contact, and the heat-conducting layer and the cover plate 1 and the box body 3 are in an adhered state. This arrangement can improve the heat conduction effect, conduct the heat of the electronic device to the cover plate 1 and / or the box body 3 more quickly, and then dissipate the heat through the cover plate 1 and / or the box body 3 to prevent the electronic control board 2 from being overheated.

[0077] In one embodiment, if Figure 1 , Figure 2 As shown, the electric control board 2 can be the operation control device of the motor, and the electric control box can be arranged at the end of the motor instead of the side of the motor (the motor is not shown in the figure), and no longer occupies the side space of the motor, thereby effectively improving the integration of the motor and effectively reducing the overall volume.

[0078] In one embodiment, if Figure 1 , Figure 2 , Figure 3 As shown, the cover plate 1 is used to connect the box body 3 and can close the end opening of the box body 3; a plurality of heat sinks 17 can be provided on the outer wall of the cover plate 1, and the heat dissipation effect is outstanding;

[0079] The first surface 22 of the electronic control board 2 is close to the cover plate 1. A first electronic device is provided on the first surface 22 of the electronic control board 2. The cover plate 1 is provided with a first heat-conducting layer corresponding to the first electronic device. The first electronic device can be in contact with the first heat-conducting layer and dissipate heat through the cover plate 1.

[0080] The first heat-conducting layer and the first electronic device are in a state of close contact, and the first heat-conducting layer and the cover plate 1 are in an adhered state. Such a setting can improve the heat-conducting effect, more quickly conduct the heat generated by the first electronic device to the cover plate 1, and then dissipate heat through the cover plate 1 to prevent the temperature of the electronic control board 2 from being too high.

[0081] The cover plate 1 includes a cover body 11. A plurality of first connecting lugs 16 are provided on the outer wall of the cover body 11 and are connected and fixed to the box body 3 through the first connecting lugs 16 and bolts 5.

[0082] The electronic control board 2 includes a board body 21. A plurality of connecting holes are provided on the board body 21 and are connected and fixed to the box body 3 through the connecting holes and bolts 4. A plurality of connecting columns 38 (refer to Figure 6 、 Figure 7 shown) are correspondingly provided in the box body 3 for fixing the electronic control board 2. The bolts 4 fixedly connect the electronic control board 2 to the connecting columns 38 to realize the installation of the electronic control board 2 in the electronic control box.

[0083] In one embodiment, as Figure 1 、 Figure 2 、 Figure 4 shown, the structure of the box body 3 is:

[0084] The box body 3 is used to connect to the motor housing and is adjacent to the cover plate 1. The box body 3 is located between the motor housing and the cover plate 1, and the box body 3 can extend into the motor housing by a part;

[0085] The second surface 23 of the electronic control board 2 is close to the box body 3. A second electronic device is provided on the second surface 23 of the electronic control board 2. The box body 3 is provided with a second heat-conducting layer corresponding to the second electronic device. The second electronic device can be in contact with the second heat-conducting layer and dissipate heat through the box body 3.

[0086] The second heat-conducting layer and the second electronic device are in a state of close contact, and the second heat-conducting layer and the box body 3 are in an adhered state. Such a setting can improve the heat-conducting effect, more quickly conduct the heat generated by the second electronic device to the box body 3, and then dissipate heat through the box body 3 to prevent the temperature of the electronic control board 2 from being too high.

[0087] The box body 3 includes a cover body 30. A plurality of second connecting lugs 37 are provided on the outer wall of the cover body 30 and are connected and fixed to the motor housing through the second connecting lugs 37 and bolts. The box body 3 can be used to set bearings to support the motor shaft.

[0088] In one embodiment, as Figure 3 、 Figure 5As shown, the first heat conduction layer includes a plurality of first heat dissipation areas. The first surface 22 of the electronic control board 2 close to the cover plate 1 includes a plurality of first areas, and at least one first electronic device is provided in each first area.

[0089] The first heat dissipation area is a solid area formed by coating a heat-conducting material on the cover plate 1. The position and shape of the first heat dissipation area are determined according to the first electronic device that needs to dissipate heat. Any two first heat dissipation areas are in a dispersed state, that is, they are not directly connected to each other. The first area is a virtual area, which can be composed of one first electronic device or multiple first electronic devices adjacent to each other. For example, the outermost edges of multiple first electronic devices are connected to form the first area. The area of the first heat dissipation area can be slightly larger than the area of the corresponding first area to ensure that the corresponding first area can be completely covered.

[0090] In one embodiment, the plurality of first heat dissipation areas correspond to the plurality of first areas one by one.

[0091] The correspondence here means that one first heat dissipation area corresponds to one first area. The number of first heat dissipation areas is equal to the number of first areas, without missing a certain first area or leaving a certain first heat dissipation area remaining. This requires at least that the position of any first heat dissipation area matches the position of the corresponding first area to facilitate the realization of the one-to-one correspondence relationship.

[0092] In one embodiment, the shape of the first heat dissipation area matches the corresponding first area.

[0093] The shape of the first heat dissipation area can be irregular, as long as it can correspond to the shape of the first area. Through this setting, the first heat dissipation area can contact the first electronic device in the first area more accurately and completely, avoiding contact deviation and affecting the heat dissipation effect. In addition, the heat-conducting material can be saved more effectively.

[0094] Figure 3 Among them, the first electronic device can be provided on the board body 21: the first electronic device one 221, the first electronic device two 222, the first electronic device three 223, the first electronic device four 224, the first electronic device five 225, the first electronic device six 226, and the first electronic device seven 227.

[0095] The first electronic device one 221 and the first electronic device two 222 belong to the components in the same first area. The first electronic device three 223 and the first electronic device four 224 belong to the components in the same first area. The first electronic device five 225, the first electronic device six 226, and the first electronic device seven 227 belong to the components in the same first area.

[0096] Figure 5Among them, the first heat dissipation areas can be the first heat dissipation area one 13, the first heat dissipation area two 14, and the first heat dissipation area three 15 provided on the cover body 11. The position and shape of the first heat dissipation area one 13 correspond to the first electronic device one 221 and the first electronic device two 222. The position and shape of the first heat dissipation area two 14 correspond to the first electronic device three 223 and the first electronic device four 224. The position and shape of the first heat dissipation area three 15 correspond to the first electronic device five 225, the first electronic device six 226, and the first electronic device seven 227.

[0097] The first heat dissipation area one 13, the first heat dissipation area two 14, and the first heat dissipation area three 15 are in a dispersed state, that is, they are not directly connected to each other. It is targeted coating rather than large-area coating, which can save heat-conducting materials, reduce manufacturing costs, and facilitate the disassembly of the electronic control board 2 during maintenance.

[0098] In one embodiment, as Figure 4 、 Figure 6 、 Figure 7 shown, the second heat-conducting layer includes a plurality of second heat dissipation areas. The second surface 23 of the electronic control board 2 close to the box body 3 includes a plurality of second areas, and at least one second electronic device is provided in each second area.

[0099] The second heat dissipation area is a solid area formed by coating the box body 3 with heat-conducting materials. The position and shape of the second heat dissipation area are determined according to the second electronic device that needs to dissipate heat. Any two second heat dissipation areas are in a dispersed state, that is, they are not directly connected to each other. The second area is a virtual area, which can be composed of one second electronic device or multiple second electronic devices adjacent to each other. For example, the outermost edges of multiple second electronic devices are connected to form the second area. The area of the second heat dissipation area can be slightly larger than the area of the corresponding second area to ensure that it can completely cover the corresponding second area.

[0100] In one embodiment, a plurality of second heat dissipation areas correspond to a plurality of second areas one by one.

[0101] The corresponding here means that one second heat dissipation area corresponds to one second area. The number of second heat dissipation areas is equal to the number of second areas, without missing a certain second area or leaving a certain second heat dissipation area. This requires at least that the position of any second heat dissipation area matches the position of the corresponding second area to facilitate the realization of the one-to-one correspondence relationship.

[0102] In one embodiment, the shape of the second heat dissipation area matches the corresponding second area.

[0103] The shape of the second heat dissipation area can be irregular, subject to being able to correspond to the shape of the second area. Through this setting, the second heat dissipation area can contact the second electronic devices in the second area more accurately and more completely, avoiding contact deviation that affects the heat dissipation effect. Additionally, heat-conducting materials can be saved more effectively.

[0104] Figure 4 Among them, the second electronic devices can be those arranged on the board body 21: the first second electronic device 231, the second second electronic device 232, the third second electronic device 233, the fourth second electronic device 234, the fifth second electronic device 235, the sixth second electronic device 236, the seventh second electronic device 237, and the eighth second electronic device 238.

[0105] The first second electronic device 231 and the second second electronic device 232 belong to components in the same second area, the third second electronic device 233 belongs to a component in a single second area, the fourth second electronic device 234 and the fifth second electronic device 235 belong to components in the same second area, the sixth second electronic device 236 and the seventh second electronic device 237 belong to components in the same second area, and the eighth second electronic device 238 belongs to a component in a single second area.

[0106] Figure 6 、 Figure 7 Among them, the second heat dissipation areas can be those arranged on the cover body 30: the first second heat dissipation area 32, the second second heat dissipation area 33, the third second heat dissipation area 34, the fourth second heat dissipation area 35, and the fifth second heat dissipation area 36. The position and shape of the first second heat dissipation area 32 correspond to the first second electronic device 231 and the second second electronic device 232, the position and shape of the second second heat dissipation area 33 correspond to the third second electronic device 233, the position and shape of the third second heat dissipation area 34 correspond to the fourth second electronic device 234 and the fifth second electronic device 235, the position and shape of the fourth second heat dissipation area 35 correspond to the sixth second electronic device 236 and the seventh second electronic device 237, and the position and shape of the fifth second heat dissipation area 36 correspond to the eighth second electronic device 238.

[0107] The first second heat dissipation area 32, the second second heat dissipation area 33, the third second heat dissipation area 34, the fourth second heat dissipation area 35, and the fifth second heat dissipation area 36 are in a dispersed state, that is, they are not directly connected to each other. It is targeted coating rather than large-area coating, which can save heat-conducting materials, reduce manufacturing costs, and facilitate the disassembly of the electronic control board 2 during maintenance.

[0108] In one embodiment, as Figure 5 shown, the cover plate 1 includes:

[0109] The first boss 12 is provided on the side of the cover plate 1 adjacent to the electronic control board 2 and protrudes towards the electronic control board 2 (i.e., protrudes along the axial direction of the motor), so that the first boss 12 is close to the first electronic device. The first heat-conducting layer is provided on the first boss 12. Specifically, the first heat-dissipating area one 13, the first heat-dissipating area two 14, and the first heat-dissipating area three 15 are provided on the top of the first boss 12.

[0110] The first boss 12 can shorten the distance between the side of the cover plate 1 adjacent to the electronic control board 2 and the first electronic device, so that the first heat-conducting layer can be in close contact with the first electronic device to improve the heat dissipation effect.

[0111] In one embodiment, as Figure 6 、 Figure 7 shown, the box body 3 includes:

[0112] A groove is provided at the bottom of the box body 3. The position and shape of the groove match the corresponding second heat-dissipating area, and part of the second heat-dissipating area is provided at the bottom of the groove.

[0113] In the figure, the box body 3 includes three grooves. The shape of the grooves is close to an oval and can accommodate two adjacent second electronic devices. The second heat-dissipating area one 32 is provided at the bottom of one of the grooves (this groove can accommodate the second electronic device one 231 and the second electronic device two 232), the second heat-dissipating area three 34 is provided at the bottom of one of the grooves (this groove can accommodate the second electronic device four 234 and the second electronic device five 235), and the second heat-dissipating area four 35 is provided at the bottom of one of the grooves (this groove can accommodate the second electronic device six 236 and the second electronic device seven 237).

[0114] In one embodiment, as Figure 6 、 Figure 7 shown, the box body 3 includes:

[0115] A convex edge 39 is provided at the bottom of the box body 3 and protrudes towards the electronic control board 2 (i.e., protrudes along the axial direction of the motor). The convex edge 39 surrounds to form a groove.

[0116] The convex edge 39 is provided on the cover body 30 and can be integrally manufactured with the cover body 30.

[0117] The convex edge 39 can prevent the second heat-conducting layer from flowing to other positions when the second heat-conducting layer is coated, and ensure that the position, shape, and thickness of the second heat-dissipating area meet the design requirements.

[0118] In one embodiment, as Figure 5 、 Figure 6 、 Figure 7As shown, the shape of the surface of the cover plate 1 adjacent to the electronic control board 2 conforms to the shape of the first electronic device, and the shape of the bottom of the box body 3 conforms to the shape of the second electronic device. For example, the convexities and concavities of the surface of the cover plate 1 adjacent to the electronic control board 2 are adapted to the position, shape, height, etc. of the first electronic device, and the convexities and concavities of the bottom of the box body 3 are adapted to the position, shape, height, etc. of the second electronic device. Through this setting, interference between components can be avoided, and it is also convenient to set the heat conduction layer.

[0119] In one embodiment, a first gap is provided between the surface of the cover plate 1 adjacent to the electronic control board 2 and the first electronic device, and the distance of the first gap is less than or equal to the thickness of the first heat conduction layer; this is more suitable for coating the first heat conduction layer, and the distance of the first gap can be selected as 1 - 2 mm;

[0120] A second gap is provided between the bottom of the box body 3 and the second electronic device, and the distance of the second gap is less than or equal to the thickness of the second heat conduction layer. This is more suitable for coating the second heat conduction layer, and the distance of the second gap can be selected as 1 - 2 mm.

[0121] In one embodiment, as Figure 6 、 Figure 7 shown, the box body 3 includes:

[0122] A second boss 31, the second boss 31 is provided at the bottom of the box body 3 and protrudes towards the electronic control board 2 (also protruding along the axial direction of the motor), and part of the second heat dissipation area is provided on the second boss 31. Specifically, the second heat dissipation area two 33 and the second heat dissipation area five 36 are provided on the top of the second boss 31.

[0123] The second boss 31 can shorten the distance between the bottom of the box body 3 and the second electronic device, so that the second heat conduction layer can be in a state of being in close contact with the second electronic device to improve the heat dissipation effect.

[0124] In one embodiment, the first heat conduction layer and the second heat conduction layer are heat conductive silicone grease layers, and other suitable types of heat conduction layers can also be selected.

[0125] Correspondingly, the first heat dissipation area one 13, the first heat dissipation area two 14, and the first heat dissipation area three 15 are all heat conductive silicone grease layers, and the second heat dissipation area one 32, the second heat dissipation area two 33, the second heat dissipation area three 34, the second heat dissipation area four 35, and the second heat dissipation area five 36 are all heat conductive silicone grease layers.

[0126] In one embodiment, as Figure 3 、 Figure 4 shown, the first electronic device includes at least transistor-type electronic components, and the second electronic device includes at least capacitor-type electronic components.

[0127] The transistor can be a diode, a triode, a MOS transistor, etc. Transistor-type electronic components are usually various integrated circuit modules. When the electronic control board 2 is working, the heat generated by the transistor-type electronic components is often relatively high. Therefore, by arranging the transistor-type electronic components close to the cover plate 1, heat dissipation can be achieved more quickly. The heat generated by the capacitor-type electronic components is relatively low. Therefore, the capacitor-type electronic components are arranged close to the box body 3.

[0128] The first electronic device and the second electronic device may also include other types of electronic components, such as resistor-type electronic components, inductors, etc.

[0129] The second aspect of the present utility model provides a motor, including the electronic control device 100 described in any one of the above embodiments.

[0130] The motor can be an electric motor, an engine, or an integrated motor-generator, and generally includes a rotor and a stator. The specific structure and working principle can refer to the prior art and will not be elaborated here in detail.

[0131] The motor includes a motor housing. The box body 3, the electronic control board 2, and the cover plate 1 can be sequentially arranged at the rear end of the motor housing. A bearing seat 6 can be arranged on the box body 3 for installing and fixing the rotor shaft.

[0132] The third aspect of the present utility model provides a vehicle, including the motor described in any one of the above embodiments.

[0133] For an electronic control device, a motor, and a vehicle of the present utility model, by providing a first heat-conducting layer for the first electronic device, the first heat-conducting layer connects the first electronic device and the cover plate 1, and a second heat-conducting layer for the second electronic device, the second heat-conducting layer connects the second electronic device and the box body 3, the heat dissipation effect of the electronic control board 2 is improved. The first heat-conducting layer and the second heat-conducting layer are coated in a targeted manner rather than a large-area coating, which can save heat-conducting materials, reduce manufacturing costs, and facilitate the disassembly of the electronic control board 2 during maintenance.

[0134] The processes and steps described in all the above preferred embodiments are only examples. Unless adverse effects occur, various processing operations can be carried out in an order different from that of the above processes. The order of the steps of the above processes can also be increased, combined, or deleted according to actual needs.
