Description

Technical Field

[0001] This invention relates to the field of new energy motor equipment technology, and more specifically, to an integrated new energy motor controller upper housing assembly. Background Technology

[0002] The upper housing assembly of the new energy motor controller, as a key protective and structural component, is typically made of high-strength die-cast aluminum alloy, combining lightweight design with excellent heat dissipation. Its core function is to provide a safe, sealed space for the internal power modules and control circuits, effectively preventing dust and water damage and achieving electromagnetic shielding. The housing design integrates cooling water channels and electrical connection ports, meeting the requirements for efficient thermal management and reliable assembly. It is a crucial foundational component for ensuring stable controller operation and improving overall vehicle performance.

[0003] Patent application number CN202410849002.1 discloses a compact, high-heat-dissipation motor controller drive module structure, including a water-cooled radiator with a mounting cavity. A thin-film capacitor is installed in the mounting cavity. Cooling channels are arranged around the outer ring of the mounting cavity on the water-cooled radiator. A ceramic heat-conducting sheet for improving heat conduction efficiency is fixedly installed on the upper surface of the heat-conducting cover plate. A three-phase output copper busbar is fixedly installed on the upper end of the thin-film capacitor. The heat is carried away by the water-cooled radiator shell and the water channels on the four sides, which improves the heat dissipation effect of the thin-film capacitor, reduces the overall capacitor cost, and reduces the assembly of the thin-film capacitor.

[0004] However, existing new energy motor controller housing assemblies typically rigidly fix the cooling system to the housing structure, lacking modular expansion capabilities. This makes it difficult to upgrade ordinary housings to liquid-cooled heat dissipation housings, and leaks are prone to occur at the coolant disassembly interface during maintenance, increasing maintenance difficulty and pollution risk. At the same time, their heat dissipation methods are often singular or the liquid cooling and air cooling systems are independent of each other with poor coordination, resulting in limited heat dissipation efficiency, complex structure, and high energy consumption.

[0005] In view of this, we propose an integrated new energy motor controller upper housing assembly. Summary of the Invention

[0006] The purpose of this invention is to provide an integrated new energy motor controller housing assembly, which uses a driver to synchronously drive a gear and a cooling fan via a single motor, thereby achieving both liquid cooling circulation and forced air cooling, in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: An integrated new energy motor controller upper housing assembly includes a liquid-cooled heat dissipation shell and a control component disposed on its top; The liquid cooling heat sink includes a fixed shell with a liquid cooling flow path inside, a pair of guide pipes rotating on the inner wall of the liquid cooling flow path collection area of ​​the fixed shell, and a fixed plate disposed on the outside of the guide pipes. The guide pipes have several guide grooves at the opening and several liquid inlet grooves at the end. The fixed plate has several liquid passage grooves inside. In the above setup, the relative position of the liquid inlet tank and the liquid outlet tank is changed by controlling the rotation of the guide pipe, thereby controlling the opening and closing of the liquid cooling flow path; The control assembly includes a gear compartment disposed in the liquid cooling flow path collection area of ​​the fixed housing, a pair of gears rotating inside the gear compartment and meshing with each other, a driver for controlling the rotation of the gears, and liquid passage pipes disposed on the outer walls of the left and right sides of the gear compartment. The driver described above drives the gear to rotate, generating pumping power within the gearbox, which causes the coolant to circulate in the open flow path; The fluid passage includes a connecting pipe extending to the inner wall of the gear compartment and a telescopic pipe sliding on the outer side of the gear compartment. The outer wall of the telescopic pipe is provided with several protrusions, and the telescopic pipe is coaxially sleeved with the connecting pipe.

[0009] In the technical solution of the present invention, a confluence groove is provided inside the fixed housing at the position of the heat dissipation fins, a plurality of flow grooves communicating with the confluence groove are provided inside the fixed housing, and a placement groove is provided at the position of the placement of the control component.

[0010] In the technical solution of the present invention, the guide tube is rotatably connected to the end wall of the placement groove in the fixed housing, and the two fixed plates are respectively snapped and fixed at the position where the placement groove is connected to the confluence groove and the flow groove.

[0011] In the above configuration, the liquid cooling heat sink achieves the opening, closing and switching of the coolant flow channel through the flow path inside the fixed housing, the rotatable guide pipe and the fixed plate with the liquid channel, thus providing a structural basis for selective liquid cooling heat dissipation.

[0012] In the technical solution of the present invention, the liquid cooling heat sink further includes a pair of limiting parts disposed inside the placement groove. The limiting parts include a fixed cylinder, a limiting rod slidably connected inside the fixed cylinder and having an inclined chamfer at its end, and a spring adhered and fixed to the limiting rod and the bottom surface of the placement groove wall.

[0013] In the above configuration, the limiting part, through its fixed cylinder, spring, and limiting rod with inclined chamfer, provides reliable elastic positioning and limiting functions for subsequent linkage with the control components.

[0014] In the technical solution of the present invention, the control component includes a base plate fixedly connected to the top surface of the sealing plate by screws, a cover plate fixedly connected to the center of the top surface of the base plate by screws, a fixing frame welded and fixed to the top surface of the base plate, a top plate snapped and fixed to the opening of the top surface of the fixing frame, and a filter screen snapped and fixed to the outer wall of the left side of the fixing frame.

[0015] In the technical solution of the present invention, the gear compartment and the base plate are integrally formed, and a partition and a guide plate disposed on the left side of the partition are integrally formed on the inner wall of the fixed frame. The guide plate is inclined with the left side lower and the right side higher, and is used to guide the airflow to the direction of the filter screen.

[0016] In the above configuration, the control components, through the integrated design of the base plate, gear compartment, fixed frame, guide plate and top plate, constitute a modular unit that combines hydraulic pumping, air-cooled flow guidance and overall encapsulation functions.

[0017] In the technical solution of the present invention, the driver includes a motor, a worm coaxially connected to the output shaft of the motor, a worm wheel perpendicularly meshing with the worm, a rotating shaft snapped and fixed at the center of the worm wheel, and a cooling fan snapped and fixed at the end of the central shaft of the worm. A storage compartment is sleeved on the outer side of the worm and the worm wheel. The storage compartment is fixedly connected to the top surface of the cover plate by screws. The motor is snapped and fixed to the outer wall of the storage compartment. The bottom end of the rotating shaft extends to the bottom of the cover plate and is fixedly connected to the gear by a snap pin. The cooling fan is fixedly connected to the outer wall of the partition by screws.

[0018] In the above setup, the driver enables a single power source to simultaneously drive the gear pump for fluid and the cooling fan for airflow, achieving efficient and coordinated heat dissipation.

[0019] In the technical solution of the present invention, the connecting pipe is fixedly connected to the outer wall of the gear compartment by bolts, the top end of the telescopic pipe is fixedly attached with a lever, and a sealing ring is adhered to the telescopic pipe near the end.

[0020] In the technical solution of the present invention, the control component further includes a toggle block slidably connected to the base plate. The top surface of the toggle block is provided with two limiting holes and its end is provided with an inclined toggle groove. In the above configuration, the telescopic tube of the liquid passage cooperates with the guide groove through the protrusion, and the actuating block is designed with a groove and a limiting hole to convert the external manual operation into the precise rotation and locking of the guide tube, thereby realizing reliable switching control of the flow path.

[0021] Compared with the prior art, the beneficial effects of the present invention are: 1. The upper housing assembly of this integrated new energy motor controller has the control component as an independent module. It can be connected to the liquid cooling heat sink with liquid cooling flow path inside through a sliding telescopic tube. The telescopic tube can synchronously drive the guide tube to rotate, change the relative position of the liquid inlet tank and the liquid outlet tank, thereby controlling the opening and closing of the liquid cooling flow path, preventing leakage problems in the liquid cooling flow path during assembly and disassembly, and simplifying the maintenance process.

[0022] 2. The upper housing assembly of this integrated new energy motor controller uses a single motor to synchronously drive gears and a cooling fan, simultaneously achieving liquid cooling circulation and forced air cooling. The airflow from the cooling fan directly acts on the heat dissipation fins, which are partially embedded in the housing and partially exposed in the air duct, enabling liquid cooling and air cooling to work synergistically and improve the overall heat dissipation efficiency of the upper housing.

[0024] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0025] Please see Figures 1-7 As shown, this embodiment provides the following technical solution: An integrated new energy motor controller upper housing assembly includes a liquid-cooled heat dissipation shell 100 and a control component 200 disposed on its top; Specifically, the liquid cooling heat sink 100 includes a fixed housing 110 with a liquid cooling flow path inside, a pair of guide pipes 150 rotating on the inner wall of the liquid cooling flow path collection area of ​​the fixed housing 110, and a fixed plate 160 disposed outside the guide pipes 150. The guide pipes 150 have a plurality of guide grooves 151 at the opening and a plurality of liquid inlet grooves 152 at the end. The fixed plate 160 has a plurality of liquid passage grooves 161 inside.

[0026] Furthermore, the liquid cooling heat sink 100 also includes a sealing plate 120 fixedly connected to the top of the fixed housing 110 by bolts, heat dissipation fins 130 welded and fixed to the top of the sealing plate 120, and a sealing plug 140 threadedly connected to the corner of the top surface of the sealing plate 120. A through groove 121 is also provided on the top surface of the sealing plate 120, and the bottom end of the heat dissipation fins 130 extends to the bottom of the sealing plate 120.

[0027] Furthermore, the fixed housing 110 has a confluence groove 111 at the position of the heat dissipation fin 130, and a plurality of flow grooves 112 connected to the confluence groove 111 are provided inside the fixed housing 110. The fixed housing 110 has a placement groove 113 at the position where the control component 200 is placed, which is the liquid cooling flow path collection area.

[0028] Furthermore, the guide tube 150 is rotatably connected to the end wall of the placement groove 113 in the fixed housing 110, and the two fixing plates 160 are respectively snapped and fixed at the positions where the placement groove 113 is connected to the confluence groove 111 and the flow groove 112.

[0029] Furthermore, during the installation of the new energy motor controller upper housing assembly, the liquid cooling heat sink 100 is first fixedly connected to the top of the motor controller housing with bolts. The sealing plug 140 on the top of the sealing plate 120 is unscrewed, and insulating coolant is injected into the flow groove 112 and related manifold 111 of the fixed housing 110 until the liquid level reaches the lower edge of the injection hole of the sealing plug 140. Then, the sealing plug 140 is tightened again to ensure a seal.

[0030] Furthermore, by controlling the rotation of the guide pipe 150, the relative positions of the liquid inlet tank 152 and the liquid passage tank 161 are changed. When the liquid inlet tank 152 is aligned with a specific liquid passage tank 161, the liquid cooling channel connecting the manifold 111 and the corresponding flow tank 112 is opened.

[0031] In the above configuration, the liquid cooling heat sink 100 realizes the opening, closing and switching of the coolant flow channel through the flow path in the fixed housing 110, the rotatable guide pipe 150 and the fixed plate 160 with the liquid channel 161, providing a structural basis for selective liquid cooling heat dissipation.

[0032] Please see Figure 8 As shown, in this embodiment, the liquid cooling heat sink 100 also includes a pair of limiting parts 170 disposed inside the placement groove 113. The limiting part 170 includes a fixing cylinder 171, a limiting rod 172 slidably connected inside the fixing cylinder 171 and having an inclined chamfer at its end, and a spring 173 adhered and fixed to the limiting rod 172 and the bottom surface of the groove wall of the placement groove 113.

[0033] Furthermore, the fixed cylinder 171 provides a sliding range for the limiting rod 172, and the elastic force provided by the spring 173 pushes the limiting rod 172 to move upward, thereby limiting the movement range of the internal structure of the control assembly 200.

[0034] In the above configuration, the limiting part 170, through its fixed cylinder 171, spring 173 and limiting rod 172 with inclined chamfer, provides reliable elastic positioning and limiting functions for subsequent linkage with the control component 200.

[0035] Please see Figures 9-11 As shown, in this embodiment, the control component 200 includes a gear compartment 211 disposed in the liquid cooling flow path collection area of ​​the fixed housing 110, a pair of gears 230 rotating inside the gear compartment 211 and meshing with each other, a driver 240 for controlling the rotation of the gears 230, and liquid passage pipes 250 disposed on the outer walls of the left and right sides of the gear compartment 211. The driver 240 drives the gears 230 to rotate, forming a pumping force in the gear compartment 211, causing the coolant to circulate in the open flow path.

[0036] Specifically, the control component 200 includes a base plate 210 fixedly connected to the top surface of the sealing plate 120 by screws, a cover plate 220 fixedly connected to the center of the top surface of the base plate 210 by screws, a fixing frame 270 welded and fixed to the top surface of the base plate 210, a top plate 280 snapped and fixed to the opening on the top surface of the fixing frame 270, and a filter screen 290 snapped and fixed to the left outer wall of the fixing frame 270.

[0037] Furthermore, the gear compartment 211 is integrally formed with the base plate 210, and the inner wall of the fixing frame 270 is integrally formed with a partition 271 and a guide plate 272 disposed on the left side of the partition 271. The guide plate 272 is inclined with the left side lower and the right side higher, and is used to guide the airflow to the direction of the filter screen 290.

[0038] Furthermore, the base plate 210 serves as a fixing platform for the cover plate 220 and the fixing frame 270. After the cover plate 220 is fixed, it cooperates with the gear chamber 211 to form a sealed area outside the pair of gears 230. When the pair of gears rotate, pumping power is generated in the gear chamber 211. The partition plate 271 on the fixing frame 270 provides a placement platform for the structure in the driver 240. At the same time, the guide plate 272 is used to guide the airflow in the direction of the filter screen 290. After the top plate 280 is snapped and fixed to the top of the fixing frame 270, the overall encapsulation of the controller housing assembly is completed.

[0039] In the above configuration, the control component 200, through the integrated design of the base plate 210, gear compartment 211, fixed frame 270, guide plate 272 and top plate 280, constitutes a modular unit that combines hydraulic pumping, air-cooled flow guidance and overall encapsulation functions.

[0040] Please see Figure 12As shown, in this embodiment, the driver 240 includes a motor 241, a worm gear 242 coaxially connected to the output shaft of the motor 241, a worm wheel 243 perpendicularly meshing with the worm gear 242, a rotating shaft 244 snapped and fixed at the center of the worm wheel 243, and a cooling fan 245 snapped and fixed at the end of the central shaft of the worm gear 242. A storage compartment 246 is sleeved on the outer side of the worm gear 242 and the worm wheel 243. The storage compartment 246 is fixedly connected to the top surface of the cover plate 220 by screws. The motor 241 is snapped and fixed to the outer wall of the storage compartment 246. The bottom end of the rotating shaft 244 extends to the bottom of the cover plate 220 and is fixedly connected to the gear 230 by a snap pin. The cooling fan 245 is fixedly connected to the outer wall of the partition plate 271 by screws.

[0041] Furthermore, when the motor controller starts working and requires heat dissipation, the motor 241 starts and drives the rotating shaft 244 and the gear 230 at its bottom to rotate via the worm gear 242 and worm wheel 243. The meshing pair of gears 230 rotate within the gear compartment 211 to generate pumping power, which pumps the coolant into the opened liquid cooling flow path through the connecting pipe 251 and the telescopic pipe 252, realizing the directional circulation of the coolant within the fixed housing 110.

[0042] Furthermore, when the driver 240 is operating, the cooling fan 245, coaxially connected to the worm gear 242, rotates synchronously. The airflow generated by the cooling fan 245 is directed towards the filter 290 within the fixed frame 270 by the guide plate 272. This forced airflow not only helps to cool the driver 240 itself, but also enhances the air convection in the area of ​​the heat sink fins 130, improving the auxiliary cooling effect. In the above configuration, the driver 240 enables a single power source to simultaneously drive the gear 230 to pump fluid and the cooling fan 245 to blow air, achieving efficient and coordinated heat dissipation.

[0043] Please see Figures 13-14 As shown, in this embodiment, the fluid passage 250 includes a connecting pipe 251 extending to the inner wall of the gear compartment 211 and a telescopic pipe 252 sliding on the outer side of the gear compartment 211. The outer wall of the telescopic pipe 252 is provided with a plurality of protrusions 254. The telescopic pipe 252 is coaxially sleeved with the guide pipe 150. After the telescopic pipe 252 extends outward, the protrusions 254 can move along the trajectory of the guide groove 151, thereby driving the guide pipe 150 to rotate.

[0044] Specifically, the connecting pipe 251 is fixedly connected to the outer wall of the gear compartment 211 by bolts, the top end of the telescopic pipe 252 is fixedly attached to the lever 253, and a sealing ring 255 is adhered to the end of the telescopic pipe 252.

[0045] Furthermore, the control component 200 also includes a toggle block 260 slidably connected to the base plate 210. The top surface of the toggle block 260 is provided with two limiting holes 261 and an inclined groove 262 is provided at its end.

[0046] Furthermore, the operator moves the toggle block 260 in the control component 200 with a tool. When the toggle block 260 moves to the target position, the limit rod 172 in the limit part 170, under the elastic force of the spring 173, will have its end angled and chamfered and will be locked into the limit hole 261 corresponding to the top surface of the toggle block 260, thereby achieving mechanical locking of the position of the toggle block 260.

[0047] Furthermore, the actuating block 260 drives the lever 253 in the liquid-conducting tube 250 and the telescopic tube 252 fixed thereto to slide outward through the actuating groove 262 at its end. During this process, the protrusion 254 on the outer wall of the telescopic tube 252 is embedded and moves along the trajectory of the guide groove 151 at the opening of the guide tube 150, thereby driving the guide tube 150 to rotate.

[0048] In the above configuration, the telescopic tube 252 of the liquid passage tube 250 cooperates with the guide groove 151 through the protrusion 254, and the actuating block 260 is designed with the actuating groove 262 and the limiting hole 261 to convert the external manual operation into the precise rotation and locking of the guide tube 150, thereby realizing reliable switching control of the flow path.

[0049] Finally, it should be noted that the motor 241 involved in this invention is a general standard part or a component known to those skilled in the art. Its structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle part of this device, the motor 241 is connected to the power supply through wires. The specific connection method should refer to the working principle in this invention. The electrical components are electrically connected in the order of operation. The detailed connection methods are all known technologies in the art.

[0050] During installation, the integrated new energy motor controller housing assembly of the present invention is first fixedly connected to the top of the motor controller housing by bolts to the liquid cooling heat sink 100. The sealing plug 140 on the top of the sealing plate 120 is then unscrewed, and insulating coolant is injected into the flow channel 112 and related manifold 111 of the fixed housing 110 until the liquid level reaches the lower edge of the injection hole of the sealing plug 140. The sealing plug 140 is then tightened again to ensure a seal. Subsequently, the operator moves the toggle block 260 in the control component 200 with a tool. When the toggle block 260 moves to the target position, the limit rod 172 in the limit part 170, under the elastic force of the spring 173, will have its end tilted and chamfered and will be locked into the limit hole 261 corresponding to the top surface of the toggle block 260, thereby achieving mechanical locking of the position of the toggle block 260. The actuating block 260 drives the lever 253 in the liquid-conducting tube 250 and the telescopic tube 252 fixed thereto to slide outward through the actuating groove 262 at its end. During this process, the protrusion 254 on the outer wall of the telescopic tube 252 is embedded and moves along the trajectory of the guide groove 151 at the opening of the guide tube 150, thereby driving the guide tube 150 to rotate. After the guide tube 150 is rotated, the relative position of the liquid inlet groove 152 at its cylindrical end and the liquid passage groove 161 in the fixed plate 160 changes. When the liquid inlet groove 152 is aligned with the specific liquid passage groove 161, the liquid cooling channel connecting the manifold 111 and the corresponding flow groove 112 is opened, and the top plate 280 is snapped and fixed to the top of the fixed frame 270, completing the overall encapsulation and flow path preset of the controller upper housing assembly; Next, when the motor controller starts working and requires heat dissipation, the motor 241 starts and drives the rotating shaft 244 and the gear 230 at its bottom to rotate via the worm 242 and worm wheel 243. The meshing pair of gears 230 rotate within the gear compartment 211 to generate pumping power, which pumps the coolant into the opened liquid cooling flow path through the connecting pipe 251 and the telescopic pipe 252, realizing the directional circulation of the coolant within the fixed housing 110; When the driver 240 is working, the cooling fan 245, which is coaxially connected to the worm gear 242, rotates synchronously. The airflow generated by the cooling fan 245 is blown towards the filter 290 within the fixed frame 270 by the guide plate 272. This forced airflow not only helps the driver 240 itself to be cooled, but also strengthens the air convection in the area of ​​the heat sink 130 and improves the auxiliary heat dissipation effect.

[0051] Subsequently, when system maintenance or coolant replacement is required, the sealing plug 140 can be unscrewed for operation. To close a specific flow path or reset the system, first stop the motor 241, then overcome the spring force and move the limit rod 172 to disengage it from the limit hole 261, and then move the toggle block 260 in the opposite direction. The toggle block 260 drives the telescopic tube 252 to retract, and the protrusion 254 on it moves in the opposite direction along the guide groove 151, thereby driving the conductor tube 150 to rotate back to the initial position.

[0052] At this point, the liquid inlet tank 152 and the liquid outlet tank 161 are misaligned, and the liquid cooling flow path is closed. After releasing the toggle block 260, the limit rod 172 is once again engaged in its other limit hole 261, locking the system in the closed state, and the entire system stops working.

[0053] The foregoing description of specific exemplary embodiments of the invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the invention, as well as various different choices and variations. The scope of the invention is intended to be defined by the specification and its equivalents.
