Description

Technical Field

[0001] This disclosure relates to the field of controller technology, and more particularly to a motor controller. Background Technology

[0002] With the continuous development of electric vehicles, more and more vehicle manufacturers are beginning to pay attention to the EMC issues of the whole vehicle. Electric vehicles mainly rely on one (or more) electric drive systems to provide traction. The motor drive system mainly includes power batteries, motor controllers, motors, high-voltage cables and connectors and other electronic components. During operation, electronic components will generate a lot of heat, which will affect the normal operation of the motor controller.

[0003] In related technologies, motor controllers generate a large amount of heat during operation, affecting their normal operation. Motor controllers primarily employ three cooling methods: natural cooling, air cooling, and water cooling. Natural cooling involves installing heat sink fins or heat dissipation modules on the controller's casing, resulting in low cooling efficiency. Air cooling uses cooling fans, leading to a less compact controller structure, higher noise levels, and potential insufficient heat dissipation during high-power operation. Water cooling uses a water-cooled plate tightly connected to the power devices; however, water seepage into the controller can cause serious safety hazards, resulting in personal injury and property damage. Furthermore, water cooling suffers from poor heat exchange efficiency, inadequate overall heat dissipation, and uneven heat dissipation at low motor temperatures, leading to overheating or undercooling. Additionally, when the internal temperature of the motor controller is too high, it cannot automatically increase its heat dissipation capacity.

[0004] Therefore, it is necessary to improve one or more of the problems existing in the above-mentioned related technical solutions.

[0005] It should be noted that this section is intended to provide background or context for the technical solutions of this disclosure as set forth in the claims. The description herein does not constitute an admission that it is prior art simply because it is included in this section. Summary of the Invention

[0050] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided so that this disclosure will be more comprehensive and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art.

[0051] Furthermore, the accompanying drawings are merely illustrative diagrams of embodiments of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted. Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities.

[0052] This example implementation provides a motor controller. (See reference...) Figures 1 to 3 The motor controller may include:

[0053] The housing 100, mounting plate 120, heat dissipation baffle 130, and spraying assembly.

[0054] The mounting plate 120 is disposed inside the housing 100, and the side of the mounting plate 120 facing the top of the housing 100 is used to mount electronic components, while the side of the mounting plate 120 facing away from the top of the housing 100 is provided with a plurality of heat dissipation fins 110 for cooling the electronic components.

[0055] A heat dissipation baffle 130 is disposed inside the housing 100 and is located below the mounting plate 120. The heat dissipation baffle 130 and the mounting plate 120 form a first liquid storage cavity 140, and the heat dissipation baffle 130 and the bottom of the housing 100 form a second liquid storage cavity 150. The heat dissipation fins 110 extend into the second liquid storage cavity 150 and are connected to the inner bottom of the housing 100. The mounting plate 120 has a first medium inlet and outlet 121, and the heat dissipation baffle 130 has a second medium inlet and outlet 131. The first liquid storage cavity 140 and the second liquid storage cavity 150 are respectively used to contain cooling media.

[0056] The spraying assembly includes a water pump 200, a guide pipe 300, a connector 400, and a pipe 500. The water pump 200 is located at the bottom inner part of the housing 100, and the water pump 200 is connected to the connector 400 via the guide pipe 300. The connector 400 is rotatably connected to the pipe 500. A plurality of nozzles 510 are provided on the pipe 500, and the nozzles 510 are in communication with the pipe 500. The nozzles 510 are located above the mounting plate 120.

[0057] In one embodiment, the motor 1800 controller includes a housing 100, a mounting plate 120, a heat dissipation baffle 130, and a spraying assembly. The mounting plate 120 and the heat dissipation baffle 130 are sequentially arranged from top to bottom on two side walls of the housing 100, such that the mounting plate 120, the heat dissipation baffle 130, and the four side walls of the housing 100 form a first liquid storage chamber 140, and the heat dissipation baffle 130, the four side walls of the housing 100, and the bottom of the housing 100 form a second liquid storage chamber 150. The mounting plate 120 has a first medium inlet / outlet 121, and the heat dissipation baffle 130 has a second medium inlet / outlet 131. Both the first and second medium inlets / outlets 121 and 131 are used for the flow of cooling medium. The first and second liquid storage chambers 140 and 150 are both used to contain cooling medium.

[0058] It should be understood that several electronic components are disposed on the side of the mounting plate 120 facing the top of the housing 100, and several heat dissipation fins 110 are disposed on the side of the mounting plate 120 facing away from the top of the housing 100. The heat dissipation fins 110 are perpendicular to the mounting plate 120 and extend into the second liquid storage cavity 150. Furthermore, the top end of the heat dissipation fins 110 is connected to the mounting plate 120, and the bottom end of the heat dissipation fins 110 is connected to the inner bottom of the housing 100. The heat dissipation fins 110 are used to dissipate heat from the electronic components on the mounting plate 120. The number of heat dissipation fins 110 is set according to actual conditions, and this disclosure does not limit this.

[0059] It should also be understood that the motor 1800 controller also includes a spraying assembly. The spraying assembly includes a water pump 200, a guide pipe 300, a connector 400, and a pipe 500. The water pump 200 provides the power to circulate the cooling medium. The water pump 200 is located at the inner bottom of the housing 100, with its inlet end located within the second liquid storage chamber 150. The outlet end of the water pump 200 is connected to the inlet end of the guide pipe 300, which is connected to the inlet end of the connector 400. The outlet end of the connector 400 is connected to the inlet end of the pipe 500. Several nozzles 510 are installed on the pipe 500, each nozzle 510 communicating with the pipe 500. This configuration allows the cooling medium in the second liquid storage chamber 150 to sequentially pass through the water pump 200, guide pipe 300, connector 400, and pipe 500, finally being sprayed onto the electronic components on the mounting plate 120 via several nozzles 510 on the pipe 500. This allows for heat exchange with the hot electronic components, thus cooling them. Furthermore, the outlet end of the connector 400 is rotatably connected to the inlet end of the pipe 500, ensuring the cooling medium is evenly sprayed onto the electronic components on the mounting plate 120 through the nozzles 510, facilitating uniform cooling of the hot electronic components. The cooling medium is a fluorinated liquid.

[0060] It is important to understand that when the cooling medium in the first liquid storage chamber 140, the heat dissipation fins 110, and the second liquid storage chamber 150 is used to dissipate heat from the electronic components on the mounting plate 120, the heat from the electronic components on the mounting plate 120 is transferred to the heat dissipation fins 110 and the cooling medium in the first liquid storage chamber 140 for initial heat dissipation. The cooling medium in the second liquid storage chamber 150 passes sequentially through the water pump 200, the guide pipe 300, the connector 400, and the pipe 500, and finally through several nozzles 510 on the pipe 500, spraying the cooling medium onto the electronic components on the mounting plate 120 to exchange heat with the hot electronic components, thereby further cooling the hot electronic components.

[0061] Through the aforementioned motor 1800 controller, on the one hand, the heat dissipation baffle 130 and the mounting plate 120 form a first liquid storage chamber 140, and the heat dissipation baffle 130 and the bottom of the housing 100 form a second liquid storage chamber 150. The first liquid storage chamber 140 and the second liquid storage chamber 150 contain cooling medium. Through the combined use of the heat dissipation fins 110 and the cooling medium, heat inside the housing 100 is exchanged from the cooling medium in the first liquid storage chamber 140 and the second liquid storage chamber 150 and the heat dissipation fins 110, thereby achieving the effect of suppressing the temperature inside the housing 100; on the other hand... On the one hand, when the temperature inside the housing 100 is high and the heat exchange efficiency provided by the cooling medium and the heat dissipation fins 110 is low, the water pump 200 delivers the cooling medium in the second liquid storage chamber 150 to the nozzle 510 through the guide pipe 300 and sprays it out. The cooling medium sprayed out of the nozzle 510 will fall on the electronic components of the mounting plate 120 and take away the heat from the electronic components. The sprayed cooling medium will then be delivered to the nozzle 510 by the water pump 200 through the first medium inlet / outlet 121 and the second medium inlet / outlet 131, so as to realize the circulation and heat dissipation of the cooling medium.

[0062] Below, we will refer to Figures 1 to 6 The various parts of the motor 1800 controller described in this example embodiment will be explained in more detail.

[0063] In one embodiment, it also includes:

[0064] A first sealing plate 600 is disposed at the first medium inlet / outlet 121 for sealing the first medium inlet / outlet 121;

[0065] Metal plate 610 is disposed on the lower surface of the first sealing plate 600;

[0066] The second sealing plate 700 is disposed at the second medium inlet / outlet 131 and is used to seal the second medium inlet / outlet 131;

[0067] A fixing rod 800 is disposed between the metal plate 610 and the second sealing plate 700.

[0068] Specifically, the motor 1800 controller also includes: a first sealing plate 600, a metal plate 610, a second sealing plate 700, and a fixing rod 800. The first sealing plate 600 is disposed at the first medium inlet / outlet 121 to block the first medium inlet / outlet 121, thereby achieving a seal. The second sealing plate 700 is disposed at the second medium inlet / outlet 131 to block the second medium inlet / outlet 131, thereby achieving a seal. Furthermore, the first sealing plate 600 and the second sealing plate 700 are connected by the fixing rod 800. The lower surface of the first sealing plate 600 is provided with the metal plate 610, and further still, the fixing rod 800 is disposed between the metal plate 610 and the second sealing plate 700. The second sealing plate 700 is made of iron.

[0069] In one embodiment, it also includes:

[0070] Two contact heads 900 are respectively located at the bottom of the inner side of the second liquid storage chamber 150;

[0071] Two temperature measuring cylinders 1000 are respectively installed on the corresponding contact heads 900, and each temperature measuring cylinder 1000 penetrates the heat dissipation partition 130; wherein, the interior of the temperature measuring cylinder 1000 is used to contain mercury.

[0072] Specifically, the motor 1800 controller also includes two contact heads 900 and two temperature measuring cylinders 1000. Two contact heads 900 are disposed on the inner bottom surface of the second liquid storage chamber 150, and temperature measuring cylinders 1000 are respectively disposed on the top of the two contact heads 900, with each temperature measuring cylinder 1000 penetrating the heat dissipation baffle 130. Heat from the electronic components on the mounting plate 120 is transferred to the heat dissipation fins 110 and the cooling medium in the first liquid storage chamber 140 for initial heat dissipation. When the temperature of the electronic components on the mounting plate 120 is too high, the temperature of the cooling medium in the first liquid storage chamber 140 will rise, causing the mercury in the temperature measuring cylinder 1000 to expand.

[0073] In one embodiment, it also includes:

[0074] Two conductive contact rods 1200 are respectively disposed on the top of the corresponding temperature measuring cylinder 1000, and each conductive contact rod 1200 slides through the second sealing plate 700 so that the second sealing plate 700 can move up and down along the outer wall of the conductive contact rod 1200.

[0075] The end of the conductive contact rod 1200 near the metal plate 610 is slidably inserted into the metal plate 610 so that the metal plate 610 can move up and down along the outer wall of the conductive contact rod 1200.

[0076] Specifically, the motor 1800 controller also includes two conductive contact rods 1200. Each conductive contact rod 1200 is connected to the top of the corresponding temperature measuring cylinder 1000. The second sealing plate 700 can move up and down along the outer wall of the conductive contact rod 1200, and the metal plate 610 can also move up and down along the outer wall of the conductive contact rod 1200. This arrangement facilitates the up and down movement of the first sealing plate 600 and the second sealing plate 700.

[0077] In one embodiment, it also includes:

[0078] An electromagnet 1300 is disposed at the bottom of the second liquid storage chamber 150, and the positive and negative leads of the electromagnet 1300 are electrically connected to the contact head 900 through wires respectively.

[0079] Two elastic elements 1400 are respectively sleeved on the corresponding temperature measuring cylinders 1000, and the end of each elastic element 1400 near the contact head 900 abuts against the contact head 900, and the end of each elastic element 1400 away from the contact head 900 abuts against the second sealing plate 700; wherein, the second sealing plate 700 is made of ferrous material, and the elastic element 1400 is made of insulating material.

[0080] Specifically, the elastic element 1400 is a spring. In the initial state, the spring is in its naturally extended state. At this time, the first sealing plate 600 is located at the first medium inlet / outlet 121, and the second sealing plate 700 is located at the second medium inlet / outlet 131. When the temperature of the electronic components on the mounting plate 120 is too high, the temperature of the cooling medium in the first liquid storage chamber 140 will rise. The high temperature causes the mercury in the temperature measuring cylinder 1000 to expand. When the mercury in the temperature measuring cylinder 1000 touches the conductive contact rod 1200, the conductive contact rod 1200, the contact head 900, and the elastic element 1400 form a circuit and are connected in series with the conductive metal plate 610, so that the circuit of the electromagnet 1300 forms a circuit. At this time, the electromagnet 1300 generates magnetism to attract the second sealing plate 700. The downward moving second sealing plate 700 drives the first sealing plate 600 to move simultaneously, thereby opening the first medium inlet / outlet 121 and the second medium inlet / outlet 131. The cooling medium in the second liquid storage chamber 150 passes sequentially through the water pump 200, the guide pipe 300, the connector 400, and the pipe 500. Finally, it is sprayed onto the electronic components on the mounting plate 120 through several nozzles 510 on the pipe 500, where it exchanges heat with the electronic components to cool them down again.

[0081] In one embodiment, it also includes:

[0082] A metal contact plate 620 is disposed at one end of the second sealing plate 700.

[0083] Two electrode contacts 1500 are disposed at the bottom of the second liquid storage chamber 150, and the two electrode contacts 1500 are located directly below the metal contact plate 620;

[0084] The water pump 200 includes two pins, and each pin is electrically connected to the corresponding electrode contact 1500 via a wire.

[0085] Specifically, the two pins of the water pump 200 are electrically connected to the electrode contact 1500 via wires. One end of the second sealing plate 700 is fixedly connected to the metal contact 620 via a connecting rod. The metal contact 620 is located directly above the electrode contact 1500. When the second sealing plate 700 moves downward, the metal contact 620 moves to the upper surface of the electrode contact 1500, thus forming a circuit in the water pump 200, thereby starting the water pump 200. The water pump 200 sprays the cooling medium from the nozzle 510 onto the electronic components for cooling.

[0086] In one embodiment, it also includes:

[0087] A flow guide shell 1600 is disposed on one side of the shell 100;

[0088] A fan 1700 is mounted on the guide shell 1600, and the fan 1700 is used to cool and dissipate heat from the coolant in the guide pipe 300.

[0089] Specifically, a flow guide shell 1600 is fixedly connected to one side surface of the housing 100 of the motor 1800 controller, an L-shaped plate 1610 is fixedly connected to one side surface of the flow guide shell 1600, a fan 1700 is provided on one side of the flow guide shell 1600, the bottom end of the fan 1700 is movably inserted into the L-shaped plate 1610, a locking bolt 1620 is threadedly connected to one side surface of the flow guide shell 1600, and the locking bolt 1620 is engaged with the top end of the fan 1700, which facilitates quick disassembly of the fan 1700. The guide pipe 300 is spirally arranged and located inside the guide shell 1600. A U-shaped plate 170 is fixedly connected to the bottom of the shell 100. The inner cavity of the U-shaped plate 170 is connected to the inner cavity of the guide shell 1600. The fan 1700 delivers external air to the surface of the guide pipe 300, which increases the cooling speed of the cooling medium in the guide pipe 300. When the cooling medium is sprayed into the interior of the shell 100 again through the nozzle 510 for secondary cooling, its temperature is greatly reduced, thus improving the heat dissipation effect. The airflow blown out by the fan 1700 passes through the interior of the guide shell 1600 and the interior of the U-shaped plate 170 in sequence, and can quickly remove the heat from the bottom of the heat dissipation fins 110 exposed outside the shell 100.

[0090] In one embodiment, it also includes:

[0091] The driver component includes:

[0092] A motor 1800 is disposed on the outer top of the housing 100, and a middle connecting bar 1830 is connected to the output shaft of the motor 1800, the middle connecting bar 1830 extending into the interior of the housing 100;

[0093] The first gear 1810 is connected to the central connecting strip 1830 located inside the housing 100;

[0094] The second gear 1820 is disposed on the pipe 500 at one end away from the connector head 400, and the second gear 1820 meshes with the first gear 1810.

[0095] Specifically, the motor 1800 controller also includes a drive assembly, a motor 1800, a first gear 1810, and a second gear 1820. The motor 1800 is fixedly mounted on the top of the housing 100. The output shaft of the motor 1800 is fixedly connected to a guide plate. A protrusion is fixedly connected to one side of the guide plate off-center, and the protrusion slides and engages with one side of the connecting strip 1830. The motor 1800 drives the guide plate to rotate, causing a limiting rod on one side of the guide plate to slide inside the connecting strip 1830. This, in turn, drives the first gear 1810 to reciprocate on the top wall of the housing 100. Simultaneously, the first gear 1810 drives the second gear 1820 to reciprocate, achieving synchronous reciprocating rotation of the pipe 500, thereby causing the nozzle 510 to oscillate. The first gear 1810 is a sector gear.

[0096] In one embodiment, a limiting block 530 is further provided on the pipe 500. The limiting block 530 is sleeved on the pipe 500, and one side of the limiting block 530 near the top of the housing 100 is connected to the inner top of the housing 100. Specifically, there are two limiting blocks 530, respectively disposed at both ends of the pipe 500, and the limiting blocks 530 are rotatably sleeved on the pipe 500. The limiting blocks 530 are used to cooperate with the rotation of the pipe 500.

[0097] In one embodiment, a groove 160 is provided on the top of the housing 100, and the connecting strip 1830 extends into the groove 160. When the motor 1800 is working, the connecting strip 1830 can rotate within the groove 160. Specifically, the groove 160 on the top of the housing 100 is designed to match the connecting strip 1830, and the space of the groove 160 is large enough to allow the connecting strip 1830 to rotate within the groove 160 when the motor 1800 is working.

[0098] Through the aforementioned motor 1800 controller, on the one hand, the heat dissipation baffle 130 and the mounting plate 120 form a first liquid storage chamber 140, and the heat dissipation baffle 130 and the bottom of the housing 100 form a second liquid storage chamber 150. The first liquid storage chamber 140 and the second liquid storage chamber 150 contain cooling medium. Through the combined use of the heat dissipation fins 110 and the cooling medium, heat inside the housing 100 is exchanged from the cooling medium in the first liquid storage chamber 140 and the second liquid storage chamber 150 and the heat dissipation fins 110, thereby achieving the effect of suppressing the temperature inside the housing 100; on the other hand... On the one hand, when the temperature inside the housing 100 is high and the heat exchange efficiency provided by the cooling medium and the heat dissipation fins 110 is low, the water pump 200 delivers the cooling medium in the second liquid storage chamber 150 to the nozzle 510 through the guide pipe 300 and sprays it out. The cooling medium sprayed out of the nozzle 510 will fall on the electronic components of the mounting plate 120 and take away the heat from the electronic components. The sprayed cooling medium will then be delivered to the nozzle 510 by the water pump 200 through the first medium inlet / outlet 121 and the second medium inlet / outlet 131, so as to realize the circulation and heat dissipation of the cooling medium.
