Abstract

This invention belongs to the field of motor controller technology, specifically an intelligent motor controller. Addressing the limitation of existing liquid cooling systems that only dissipate heat from the casing, this invention proposes the following solution: a rectangular box-shaped base with an upward-opening design. C-shaped sliding tubes with openings facing the center are fixed to the inner bottom wall of the base near its four corners. Z-shaped sliders are slidably connected to each of the four C-shaped sliding tubes. Compression springs are fixed to the bottom ends of each of the four Z-shaped sliders. Each Z-shaped slider includes a mounting block extending towards the center at its bottom and a mounting protrusion extending towards the periphery of the base at its top. Through the flexible coolant bag and lifting mechanism, when the internal temperature of the device becomes too high and triggers a temperature sensor, two electromagnets are simultaneously energized. At this time, the support plate is forced to rise under the action of a triangular insert, allowing the upper surface of the flexible coolant bag to adhere to the lower surface of the drive control board, thereby accelerating heat dissipation.

Description

Technical Field

[0001] This invention relates to the field of motor controller technology, and more particularly to an intelligent motor controller. Background Technology

[0002] A motor controller is a device used to control the operation of a motor. It receives input signals and uses these signals to control the motor's speed, direction, and other related parameters. Motor controllers are typically electronic devices that use electronic components and algorithms to implement control functions. They are mainly used in fields such as automobiles. The proper functioning of the controller directly affects the normal operation of the equipment system; therefore, ensuring the safe and reliable use of the controller is crucial.

[0003] The power module is the main heat source of the entire controller. The drive control board it uses is a heat-generating component. The loss of the drive control board accounts for more than 80% of the total power of the heat-generating components in the chassis. The heat dissipation efficiency of the drive control board directly affects the overall heat dissipation effect of the motor controller. Existing motor controllers will set a water-cooling circuit on the bottom of the chassis to achieve heat dissipation. However, this water-cooling circuit can only cool the chassis and cannot directly act on the heat-generating components. Therefore, under extreme conditions, the heat dissipation capacity will still be poor. Summary of the Invention

[0004] To overcome the aforementioned shortcomings of the prior art, the present invention aims to provide a novel heat dissipation structure that allows the water-cooling circuit to directly contact the heat-generating component under extreme high-temperature conditions. This invention provides an intelligent controller for an electric motor, comprising a base with an upward-opening, rectangular box-like structure. C-shaped sliding tubes with openings facing the center are fixed to the inner bottom wall of the base near its four corners. Z-shaped sliders are slidably connected to each of the four C-shaped sliding tubes. Compression springs are fixed to the bottom ends of each of the four Z-shaped sliders. Each Z-shaped slider includes a mounting block extending towards the center at its bottom and mounting protrusions extending towards the periphery of the base at its top. A common drive control board is fixed between the upper surfaces of the four mounting blocks, and a common main control board is fixed between the top ends of the four mounting protrusions. A flexible coolant bag is disposed at the bottom of the base below the drive control board, and a lifting mechanism is disposed below the flexible coolant bag. The lifting mechanism includes components attached to the flexible coolant bag. The lower surface of the support plate has symmetrical triangular lifting blocks fixed to its two ends. The bottom inner wall of the base has triangular plates that can slide synchronously towards the middle at both ends near the support plate. Permanent magnets are embedded at the opposite ends of the two triangular plates. Electromagnets are fixed at the bottom of the base near the corresponding permanent magnets. A temperature sensor is also installed inside the base. The temperature sensor is connected to a control module via a signal line, and the power supply end of the electromagnet is connected to the control module. When the internal temperature of the device is too high and triggers the temperature sensor, it will control the two electromagnets to be energized simultaneously. At this time, the support plate is forced to rise under the action of the triangular plates, so that the upper surface of the flexible coolant bag is attached to the lower surface of the drive control board, thereby accelerating the dissipation of heat.

[0005] A further feature of this invention is that a cover plate is fixed to the top of the base, and the upper surface of the cover plate is provided with heat dissipation ribs distributed at equal intervals. Capacitor modules are provided at two corners near one end of the bottom inner wall of the base. A cantilever rod is inserted into the side of the base near the middle, and one end of the cantilever rod inside the device extends horizontally to the middle of the upper surface of the drive control board. With this arrangement, the temperature sensor can be placed in the most sensitive and important position, thereby playing a safety role.

[0006] A further feature of this invention is that the cantilever rod is made of a bendable metal material, which facilitates the adjustment of the spatial position of the temperature sensor.

[0007] A further feature of this invention is that the bottom inner wall of the base is fixed with transverse slide rails on both sides near each triangular insert, and each side of the triangular insert has a sliding block that matches the transverse slide rail. When the electromagnet is energized, the magnetic pole of the end of the permanent magnet on the same side is the same, so a repulsive force is generated at the same time, which pushes the two triangular inserts towards the middle at the same time, and then the combined force under the action of the triangular lifting block lifts the support plate.

[0008] A further feature of this invention is that an air inlet is provided on the side of the base on the same side as the cantilever rod, and a filter screen is provided on the surface of the air inlet. An exhaust module is provided in the middle of the side of the base away from the air inlet, and the exhaust module is an exhaust fan. The height of the exhaust module is located at the middle height after the main control board and the drive control board are positioned. It can work with the flexible coolant bag to accelerate the discharge of internal heat and prevent dust from entering the equipment during the heat dissipation process.

[0009] A further feature of this invention is that the outer wall of the base has multiple wiring ports near the capacitor module; a diaphragm is provided in the middle of the flexible coolant bag, which divides the interior of the flexible coolant bag into two chambers, front and rear. An inlet pipe and an outlet pipe extending outwards are respectively connected to the ends of the two chambers away from the capacitor module. Two connecting pipes are connected to the end of the flexible coolant bag near the capacitor module, and a single hydraulic high-temperature circuit breaker is provided between the two connecting pipes. Under normal load conditions, the interior of the hydraulic high-temperature circuit breaker is in an unobstructed communication state, allowing the coolant to reflux within the flexible coolant bag, thereby carrying away heat from a larger contact area and improving cooling efficiency.

[0010] A further feature of this invention is that a limiting notch is reserved at the top of the C-shaped slide tube away from the opening, and two side guard plates are reserved at the limiting notch. The two side guard plates are respectively provided with coaxial screw holes of the same height, and a pin stud is screwed into the screw hole. The side of the mounting protrusion two at the top of the Z-shaped slider is provided with a pin hole that matches the diameter of the pin stud. This allows the drive control board and the main control board to be relatively independent after installation, thereby reducing the direct impact of external vibration on both. It also allows the distance between the drive control board and the surface of the flexible coolant bag below it to be adjusted as needed.

[0011] A further feature of the present invention is that a downwardly recessed protruding bottom shell is reserved in the middle of the bottom of the base, and a heat dissipation groove is reserved on the side of the protruding bottom shell near the support plate.

[0012] A further feature of this invention is that the hydraulic high-temperature circuit breaker includes an outer frame, the outer frame being a vertical rectangular frame structure, and a vertical reversing pipe being disposed in the middle of the outer frame. The reversing pipe is a circular tube structure, and a reversing cavity with an inner diameter larger than that at both ends is reserved in the middle of the inner circumference of the reversing pipe. A branch pipe connected to one of the connecting pipes is inserted into the side wall of the reversing cavity. A main piston plate is also slidably connected in the reversing cavity, and the upper and lower sides of the main piston plate are respectively fixed with the same The shaft has a column, with sealing piston discs fixed at its upper and lower ends. Return pipe one and return pipe two are respectively inserted into the small-diameter cavities at the upper and lower ends of the reversing cavity. A return spring and a passive stop rod are fixed to the upper and lower sides of the two sealing piston discs, respectively. A spring baffle is fixed to the top of the return spring, and both ends of the spring baffle are fixed to the top of the reversing pipe. A sliding bearing is engaged at the bottom end of the reversing pipe, and the passive stop rod is slidably inserted into the sliding bearing. The inner part of the outer frame, near the lower part of the passive stop rod... The circuit is equipped with a bimetallic strip, and a resistance wire is installed below the end of the bimetallic strip. The resistance wire is connected in series in the motor circuit. The outlet end of the return pipe one near the top is connected to a branch pipe two, which is connected to another connecting pipe. The other end of the branch pipe two and the end of the return pipe two are connected to the same piston cylinder. The piston rod end of the piston cylinder is equipped with a movable connecting piece, and the two ends of the movable connecting piece are respectively equipped with metal gasket one and metal gasket two connected in series in the circuit. When the load in the motor is too large, the current increases and the resistance wire heats up, which causes the end of the bimetallic strip to bend. This causes the main piston plate to rise, so that the coolant changes its flow channel and flows into the piston cylinder from the return pipe two. This causes the connected movable connecting piece to break, thereby achieving a temporary circuit break, avoiding continuous power supply to the motor and protecting the motor. At this time, if the controlled motor module is overloaded, the resistance wire will heat up abnormally, which will trigger the hydraulic power high temperature circuit breaker to break the circuit. This circuit breaking through temperature control is more secure and reliable.

[0013] A further feature of this invention is that a one-way valve is provided at both the return pipe connected to the second branch pipe and at the section flowing out from the piston cylinder, thereby ensuring the normal circulation of coolant under normal circumstances.

[0014] The beneficial effects of this invention are as follows: 1. Through the flexible coolant bag and lifting mechanism, when the internal temperature of the device is too high and triggers the temperature sensor, it will control two electromagnets to be energized simultaneously. At this time, the support plate is forced to rise under the action of the triangular plate, so that the upper surface of the flexible coolant bag is attached to the lower surface of the drive control board, thereby accelerating the dissipation of heat.

[0015] 2. By using a diaphragm inside the flexible coolant bag, the coolant can flow back inside the bag, thereby carrying away heat from a larger contact area and improving cooling efficiency.

[0016] 3. By using the set pin studs and compression springs, the drive control board and the main control board can be made relatively independent after installation, thereby reducing the direct impact of external vibration on both. The distance between the drive control board and the surface of the flexible coolant bag below it can also be adjusted as needed.

[0017] 4. With this configuration, when the load on the motor is too high, the increased current and heating of the resistance wire will cause the end of the bimetallic strip to bend, which in turn will drive the main piston plate to rise. This will cause the coolant to change its flow path and flow from the return pipe into the piston cylinder, which will then cause the connected movable connecting piece to disconnect, thereby achieving a temporary circuit break, preventing the motor from being continuously powered and protecting the motor.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] In this embodiment, refer to Figure 1-10A smart controller for an electric motor includes a base 1 with an overall rectangular box-like structure and an upward-opening design. C-shaped sliding tubes 14 with openings facing the center are fixed to the inner bottom wall of the base 1 near the four corners. Z-shaped sliders 13 are slidably connected to each of the four C-shaped sliding tubes 14. Compression springs 24 are fixed to the bottom ends of each of the four Z-shaped sliders 13. Each Z-shaped slider 13 includes a mounting block 131 extending towards the center at its bottom end and mounting protrusions 132 extending towards the periphery of the base 1 at its top end. A common drive control board 15 is fixed between the upper surfaces of the four mounting blocks 131, and a common main control board 11 is fixed between the top ends of the four mounting protrusions 132. A flexible coolant bag 16 is disposed at the bottom of the base 1 below the drive control board 15, and a lifting mechanism is disposed below the flexible coolant bag 16. The lifting mechanism includes a support plate 22 attached to the lower surface of the flexible coolant bag 16. Two symmetrical triangular lifting blocks 21 are fixed to the lower surfaces of the two ends of the base 2. Triangular inserts 20 that can slide synchronously toward the middle are respectively provided on the bottom inner wall of the base 1 near the two ends of the support plate 22. Permanent magnets 19 are embedded in the opposite ends of the two triangular inserts 20. Electromagnets 18 are fixed to the bottom of the base 1 near the corresponding permanent magnets 19. A temperature sensor 12 is also provided inside the base 1. The temperature sensor 12 is connected to the control module through a signal line, and the power supply end of the electromagnet 18 is connected to the control module. Through the flexible coolant bag 16 and the lifting mechanism, when the internal temperature of the device is too high and triggers the temperature sensor 12, it will control the two electromagnets 18 to be energized at the same time. At this time, the support plate 22 is forced to rise under the action of the triangular inserts 20, so that the upper surface of the flexible coolant bag 16 is attached to the lower surface of the drive control plate 15, thereby accelerating the dissipation of heat.

[0022] Reference Figure 3 and Figure 4 The top of the base 1 is also fixed with a cover plate 2, and the upper surface of the cover plate 2 is provided with heat dissipation ribs 201 distributed at equal intervals. Capacitor modules 10 are provided at two corners near one end of the bottom inner wall of the base 1. A cantilever rod 4 is inserted into the side of the base 1 near the middle, and the end of the cantilever rod 4 located inside the device extends horizontally to the middle of the upper surface of the drive control board 15. With this arrangement, the temperature sensor 12 can be placed in the most sensitive and important position, thereby playing a safety role.

[0023] In this invention, the cantilever rod 4 is made of a bendable metal material, which facilitates the adjustment of the spatial position of the temperature sensor 12.

[0024] Reference Figure 5 and Figure 6The bottom inner wall of the base 1 is fixed with horizontal slide rails 23 on both sides near each triangular plate 20, and sliding blocks adapted to the horizontal slide rails 23 are reserved on both sides of the triangular plate 20. When the electromagnet 18 is energized, the magnetic poles of the end of the permanent magnet 19 on the same side are the same, so a repulsive force will be generated at the same time, which will push the two triangular plates 20 towards the middle at the same time, and then the combined force of the triangular lifting block 21 will lift the support plate 22.

[0025] Reference Figure 3 An air inlet 5 is provided on the side of the base 1 on the same side as the cantilever rod 4, and a filter screen is provided on the surface of the air inlet 5. An exhaust module 8 is provided in the middle of the side of the base 1 away from the air inlet 5, and the exhaust module 8 is an exhaust fan. The height of the exhaust module 8 is located at the middle height after the main control board 11 and the drive control board 15 are positioned. With this setting, it can work with the flexible coolant bag 16 to accelerate the discharge of internal heat and prevent dust from entering the equipment during the heat dissipation process.

[0026] Reference Figures 1-3 , Figure 5 The outer wall of the base 1 has multiple wiring ports 3 near the capacitor module 10. A diaphragm is provided in the middle of the flexible coolant bag 16, which divides the interior of the flexible coolant bag 16 into two chambers. The two chambers away from the capacitor module 10 are respectively connected to an outwardly extending inlet pipe 6 and an outlet pipe 7. Two connecting pipes 17 are connected to the end of the flexible coolant bag 16 near the capacitor module 10, and the same hydraulic high-temperature circuit breaker 9 is provided between the two connecting pipes 17. Under normal load conditions, the interior of the hydraulic high-temperature circuit breaker 9 is in an unobstructed communication state. Through the diaphragm provided inside the flexible coolant bag 16, the coolant can form a backflow inside the flexible coolant bag 16, thereby carrying away heat from a larger contact area and improving cooling efficiency.

[0027] Reference Figure 7 The top of the C-shaped slide tube 14 has a limiting notch 141 reserved away from the opening, and two side guard plates are reserved at the limiting notch 141. The two side guard plates have coaxial screw holes of the same height, and the screw holes are screwed with pin studs 142. The side of the mounting protrusion 132 at the top of the Z-shaped slider 13 has a pin hole that matches the diameter of the pin stud 142. Through the set pin stud 142 and compression spring 24, the drive control board 15 and the main control board 11 can be relatively independent after installation, thereby reducing the direct impact of external vibration on the two. The distance between the drive control board 15 and the surface of the flexible coolant bag 16 below it can also be adjusted as needed.

[0028] Reference Figure 5The bottom of the base 1 has a recessed protruding bottom shell 101 in the middle, and a heat dissipation groove is reserved on the side of the protruding bottom shell 101 near the support plate 22.

[0029] Reference Figures 8-10 The hydraulic high-temperature circuit breaker 9 includes an outer frame 901, which has a vertical rectangular frame structure. A vertical reversing pipe 902 is located in the middle of the outer frame 901. The reversing pipe 902 has a circular tube structure, and a reversing cavity 914 with an inner diameter larger than both ends is reserved in the middle of the inner circumference of the reversing pipe 902. A branch pipe 904 connected to one of the connecting pipes 17 is inserted into the side wall of the reversing cavity 914. A main piston plate 913 is also slidably connected in the reversing cavity 914. Coaxial shafts are fixed to the upper and lower sides of 13, and sealing piston discs are fixed to the upper and lower ends of the shafts. Return pipe one and return pipe two are respectively inserted into the small-diameter cavities at the upper and lower ends of the reversing cavity 914. Return springs 915 and passive abutments are fixed to the upper and lower sides of the two sealing piston discs, respectively. A spring baffle 903 is fixed to the top of the return spring 915, and both ends of the spring baffle 903 are fixed to the top of the reversing tube 902. A sliding bearing 912 is engaged at the bottom end of the reversing tube 902. The sliding bearing 912 is dynamically inserted into the inner part of the outer frame 901, near the lower part of the passive abutment. A bimetallic strip 911 is provided inside the frame 901, and a resistance wire 910 is provided below the end of the bimetallic strip 911. The resistance wire 910 is connected in series in the motor circuit. The outlet end of the return pipe 1 near the top is connected to a branch pipe 2 905 that is connected to another connecting pipe 17. The other end of the branch pipe 2 905 and the end of the return pipe 2 are connected to the same piston cylinder 909. A movable connecting piece 90 is provided at the end of the piston rod of the piston cylinder 909. 7. Furthermore, the two ends of the movable connecting piece 907 are respectively provided with a metal gasket 906 and a metal gasket 908 connected in series in the circuit. With this arrangement, when the load in the motor is too large, the current increases and the resistance wire 910 heats up, causing the end of the bimetallic strip 911 to bend. This causes the main piston plate 913 to rise, which changes the flow path of the coolant and flows from the return pipe 2 into the piston cylinder 909. This causes the connected movable connecting piece 907 to disconnect, thereby achieving a temporary circuit break, preventing the motor from being continuously powered, and protecting the motor. When the circuit is normally conducting, the current flowing into the motor passes sequentially through metal pad 906, movable connecting piece 907, metal pad 908, and resistance wire 910, and then flows into the controlled motor module. That is, metal pad 906, movable connecting piece 907, metal pad 908, and resistance wire 910 are connected in series in the motor circuit. If the controlled motor module is overloaded, the resistance wire 910 will heat up abnormally, which will trigger the hydraulic high-temperature circuit breaker 9 to break the circuit. This method of breaking the circuit through temperature control is more secure and reliable.

[0030] Reference Figure 10 One-way valves are installed at the return pipe 1 connected to branch pipe 2 905 and at the section flowing out from piston cylinder 909, so as to ensure the normal circulation of coolant under normal conditions.

[0031] Working Principle: During normal use, the coolant is input through the inlet pipe 6, then through the connecting pipe 17 into the reversing pipe 902, and finally through the return pipe 1, branch pipe 2 905, and another connecting pipe 17 back to the other half of the flexible coolant bag 16. Finally, it returns to the coolant pool through the outlet pipe 7. Simultaneously, under normal load, the resistance wire 910 of the motor generates only a small amount of heat, insufficient to bend the bimetallic strip 911. When the internal temperature is too high, it first triggers the temperature sensor 12, after which the control module controls the two electromagnets. When power is applied to 18, the support plate 22 is forced to rise under the action of the two triangular inserts 20 moving towards the middle, which in turn causes the upper surface of the flexible coolant bag 16 to stick to the lower surface of the drive control board 15, accelerating the dissipation of heat. When the load in the motor is too large, the current increases and the heating of the resistance wire 910 causes the end of the bimetallic strip 911 to bend, which in turn drives the main piston plate 913 to rise, causing the coolant to change its flow path and flow from the return pipe into the piston cylinder 909, which in turn causes the connected movable connecting piece 907 to disconnect, thereby achieving a temporary circuit break.

[0032] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
