Description

Technical Field

[0001] This invention relates to the field of automotive motor manufacturing technology, specifically a high-strength motor heat dissipation housing. Background Technology

[0002] With the rapid development of new energy vehicle manufacturing technology, the power and performance of drive motors are constantly improving, and the heat generated during operation is also increasing. High temperatures can affect the efficiency and service life of motors, and even cause failures. Traditional motor heat dissipation methods and housing structures are insufficient in terms of heat dissipation efficiency, load changes, and coolant utilization, making it difficult to meet the high requirements of modern new energy vehicle manufacturing for motor heat dissipation. Therefore, it is of great significance to develop a high-efficiency, stable, and load-adaptable high-strength motor heat dissipation housing.

[0003] In existing technologies, when the motor load suddenly increases, relying solely on the motor's own output torque to maintain the speed can easily lead to a sudden drop in speed and a surge in heat generation. This not only increases the difficulty of heat dissipation but also shortens the motor's lifespan.

[0004] To address the above issues, a high-strength motor heat dissipation housing is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a high-strength motor heat dissipation housing. By using this device, the problem mentioned above can be solved in the prior art where, when the motor load suddenly increases, the motor relies solely on its own output torque to maintain the speed, which easily leads to a sudden drop in speed and a surge in heat generation. This not only increases the difficulty of heat dissipation but also shortens the service life of the motor.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A high-strength motor heat dissipation housing is provided, including a housing, an annular assembly coaxially fixed in the inner cavity of the housing, a plurality of spiral channels arranged annularly with its axis as a reference in the annular assembly, a stator coaxially fixed in the inner wall of the annular assembly, a rotor coaxial with the stator and rotatably connected to the housing, and a cam coaxially fixed on the rotor. The inner cavity of the housing is also coaxially fixed with a hydraulic component. The hydraulic component has a cylindrical hydraulic chamber that is circumferentially opened on it, corresponding to the position of the spiral channel. A plunger assembly with a temperature sensor is slidably connected inside the cylindrical hydraulic chamber. A cooling port is provided on the left side of the hydraulic component. The cooling port is connected to the spiral channel through a pipe and a heat exchange solenoid valve. The hydraulic component also has an annular cavity. A fluid exchange solenoid valve is provided at the bottom of the cylindrical hydraulic chamber where it connects with the annular cavity. A suction component is fixed on the outer wall of the housing. The suction component is connected to the annular cavity hose. The hydraulic assembly has several auxiliary ports and return ports arranged in a ring on the right side. The crankshaft is fixed to the right side of the rotor. A polygonal block is rotatably connected to the crankshaft. Several auxiliary tubes are arranged in a ring inside the housing. A piston assembly with a speed sensor is slidably connected inside the auxiliary tube. The piston assembly is slidably connected to the edge of the polygonal block. An auxiliary solenoid valve is fixed at the upper end of the auxiliary tube. The auxiliary solenoid valve is connected to the auxiliary port through a connecting pipe one. A return solenoid valve is provided on one side of the auxiliary tube. The return solenoid valve is connected to the return port through a check valve and a connecting pipe two.

[0007] The annular assembly includes an annular cooling cavity body, on which a plurality of spiral channels are formed. The plurality of spiral channels are arranged in a ring around the axis of the annular cooling cavity body, and an annular sealing plate is arranged coaxially with the annular cooling cavity body.

[0008] The annular sealing plate is fixedly connected to the annular cooling cavity body. Several liquid inlets are provided on the right side of the annular cooling cavity body. The several liquid inlets are arranged in a ring around the annular cooling cavity body. The several liquid inlets are respectively connected to several spiral channels.

[0009] The hydraulic assembly includes a connecting ring body, which is fixedly connected to the inner cavity of the housing. The connecting ring body has several cylindrical hydraulic chambers arranged in a ring around its axis. A cooling port is provided on the left side of the connecting ring body. The cooling port is connected to the spiral channel through a pipe, a heat exchange solenoid valve, and a liquid inlet. A protective shell is fixedly connected to the connecting ring body coaxially.

[0010] Each of the plunger assemblies includes a cooling piston, which is slidably connected within a cylindrical hydraulic chamber, and a temperature sensor is fixedly connected to the side of the cooling piston facing the bottom of the cylindrical hydraulic chamber.

[0011] A push rod is coaxially arranged with the cooling piston. The end of the push rod away from the rotor shaft is fixedly connected to the cooling piston. A cooling spring is sleeved on the push rod. A ball block is fixedly connected to the end of the push rod near the rotor shaft. The ball block abuts against the cam.

[0012] The assisting assembly includes an assisting piston, which is slidably connected inside an assisting tube. A speed sensor is fixedly connected to the side of the assisting piston adjacent to the bottom of the assisting tube. An assisting rod is coaxially arranged with the assisting piston. One end of the assisting rod away from the center of the polygonal block is fixedly connected to the assisting piston. A slider is fixedly connected to the end of the assisting rod near the center of the polygonal block. The slider is slidably connected to the polygonal block. A spring is sleeved on the assisting rod, and a bellows is sleeved on the outside of the spring.

[0013] The suction assembly includes a liquid storage chamber, which is fixedly connected to the outer wall of the housing. A suction piston is slidably connected inside the liquid storage chamber. A cylinder is coaxially arranged with the liquid storage chamber and is fixedly connected to the top of the liquid storage chamber. The output end of the cylinder is fixedly connected to the suction piston. The liquid storage chamber is connected to an annular cavity through a flexible tube.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The rotor causes the piston assembly to slide through the transmission action. The speed sensor monitors the piston assembly in real time. When the load increases and the speed drops suddenly, the sensor detects the change. The controller regulates the assist solenoid valve and the return solenoid valve, using the coolant pressure to push the piston assembly to move, thereby assisting the crankshaft to rotate, and in turn assisting the rotor to rotate, so as to maintain the stability of the motor rotation speed and reduce the heat generation caused by load fluctuations. 2. By setting several spiral channels arranged in a ring around the axis of the ring assembly, the flow path and residence time of the coolant in the housing are increased, allowing the coolant to absorb the heat generated by the motor more fully, thereby improving the heat dissipation efficiency. 3. A temperature sensor is fixedly connected to the plunger assembly, which can monitor the temperature of the coolant flowing back into the cylindrical hydraulic chamber in real time. When the coolant temperature is higher than the preset temperature, the temperature sensor transmits the information to the controller. The controller promptly controls the heat exchange solenoid valve to close, preventing the high-temperature coolant from continuing to circulate in the spiral channel, making the heat dissipation effect more stable and reliable. 4. The coolant is not only used for heat dissipation of the motor, but also helps the rotor of the motor to rotate when the load changes, reducing the degree of heat increase caused by the increase in load. This allows the coolant to be used in multiple ways, reducing the need for additional equipment and lowering the operating cost of the motor. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the embodiments 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] A high-strength motor heat dissipation housing is provided, as per reference. Figures 1-7 As shown, it includes a housing 1, an annular assembly 2 is coaxially fixed inside the housing 1, the annular assembly 2 has several spiral channels 3 arranged in a ring with its axis as a reference, the stator 4 is coaxially fixed inside the annular assembly 2, and the rotor 5, which is coaxial with the stator 4, is rotatably connected to the housing 1, and the cam 6 is coaxially fixed on the rotor 5. The inner cavity of the housing 1 is also coaxially fixed with a hydraulic component 7. The hydraulic component 7 has a cylindrical hydraulic chamber 71 that corresponds to the position of the spiral channel 3. The cylindrical hydraulic chamber 71 is slidably connected with a plunger assembly 8 with a temperature sensor 9. The left side of the hydraulic component 7 is provided with a cooling port 72. The cooling port 72 is connected to the spiral channel 3 through a pipe and a heat exchange solenoid valve 73. The hydraulic component 7 is also provided with an annular cavity 74. The bottom of the cylindrical hydraulic chamber 71 is provided with a fluid exchange solenoid valve 10 at the connection between it and the annular cavity 74. The outer wall of the housing 1 is fixed with a suction assembly 20. The suction assembly 20 is connected to the annular cavity 74 with a hose. The hydraulic component 7 has several auxiliary ports 75 and return ports 76 arranged in a ring on the right side. The crankshaft 30 is fixed on the right side of the rotor 5. A polygonal block 40 is rotatably connected to the crankshaft 30. Several auxiliary tubes 50 are arranged in a ring inside the housing 1. An auxiliary piston assembly 60 with a speed sensor 70 is slidably connected inside the auxiliary tube 50. The auxiliary piston assembly 60 is slidably connected to the polygonal block 40. An auxiliary solenoid valve 80 is fixed at the upper end of the auxiliary tube 50. The auxiliary solenoid valve 80 is connected to the auxiliary port 75 through a connecting pipe 1 801. A return solenoid valve 90 is provided on one side of the auxiliary tube 50. The return solenoid valve 90 is connected to the return port 76 through a check valve 100 and a connecting pipe 2 1001. When the motor is working normally, that is, when the rotor 5 rotates, it synchronously drives the cam 6, which is fixedly connected to it, to rotate. As the cam 6 rotates synchronously with the rotor 5, when the protruding part of the cam 6 rotates to the position of the plunger assembly 8, it pushes the plunger assembly 8 up, causing the plunger assembly 8 to move towards the bottom of the cylindrical hydraulic chamber 71, that is, away from the axis of the hydraulic connecting ring assembly 71. When the plunger assembly 8 moves towards the bottom of the cylindrical hydraulic chamber 71, it squeezes out the coolant in the cylindrical hydraulic chamber 71, causing the coolant to flow out through the cooling fluid port 72. This arrangement ensures that when the plunger assembly 8 moves towards the bottom of the cylindrical hydraulic chamber 71, it squeezes out the coolant in the cylindrical hydraulic chamber 71. Coolant enters the spiral liquid channel 3 sequentially through cooling port 72, pipes, and heat exchange solenoid valve 73 for cooling. When the recessed part of cam 6 rotates to the position of plunger assembly 8, cam 6 loses the squeezing force on plunger assembly 8, causing plunger assembly 8 to reset. That is, plunger assembly 8 moves towards the axis of hydraulic connecting ring assembly 7, thereby causing the coolant in the spiral liquid channel 3 to flow back into the cylindrical hydraulic chamber 71 through pipes, heat exchange solenoid valve 73, and cooling port 72. Temperature sensor 9 monitors the temperature of the coolant flowing back into the cylindrical hydraulic chamber 71. When temperature sensor 9 detects a temperature change from the spiral liquid channel 3 to the cylindrical hydraulic chamber 71, the coolant in the spiral liquid channel 3 flows back into the cylindrical hydraulic chamber 71 through pipes, heat exchange solenoid valve 73, and cooling port 72. When the temperature of the coolant flowing back from the spiral liquid channel 3 to the cylindrical hydraulic chamber 71 is higher than the preset temperature, the temperature sensor 9 transmits the monitoring information to the controller (not shown in the figure, which is existing technology). The controller controls the heat exchange solenoid valve 73 to close. When the temperature sensor 9 detects that the temperature of the coolant flowing back from the spiral liquid channel 3 to the cylindrical hydraulic chamber 71 is higher than the preset temperature, the controller controls the heat exchange solenoid valve 73 to close and simultaneously controls the fluid exchange solenoid valve 10 to open. This causes the protruding part of the cam 6 to rotate again to the position of the plunger assembly 8, pushing the plunger assembly 8 up again. As the plunger assembly 8 moves towards the bottom of the cylindrical hydraulic chamber 71, it squeezes out the higher-temperature coolant from the cylindrical hydraulic chamber 71. During this process, the higher-temperature coolant is exchanged through the fluid exchange solenoid valve 10. The solenoid valve 10 enters the annular cavity 74, and the suction assembly 20 draws out the coolant at a higher temperature from the annular cavity 74. The coolant is then cooled down; this cooling technique is existing technology and is not shown in the figure. After the coolant is cooled, the suction assembly 20 reverses its operation, forcing the cooled coolant back into the annular cavity 74. Then, when the recessed part of the cam 6 rotates to the position of the plunger assembly 8, the plunger assembly 8 moves away from the bottom of the cylindrical hydraulic chamber 71, that is, it moves closer to the axis of the hydraulic connecting ring assembly 7. At this time, the cooled coolant in the annular cavity 74 returns to the cylindrical hydraulic chamber 71 through the fluid exchange solenoid valve 10, and this process repeats.Cool the motor; By setting several spiral liquid channels 3 arranged in a ring around the axis of the annular cooling chamber assembly 2, the flow path and residence time of the coolant in the housing are increased, so that the coolant can absorb the heat generated by the motor more fully and improve the heat dissipation efficiency. A temperature sensor 9 is fixedly connected to the plunger assembly 8, which can monitor the temperature of the coolant flowing back to the columnar hydraulic chamber 71 in real time. When the coolant temperature is higher than the preset temperature, the temperature sensor 9 transmits the information to the controller. The controller promptly closes the heat exchange solenoid valve 73 to prevent the high-temperature coolant from continuing to circulate in the spiral liquid channel 3, making the heat dissipation effect more stable and reliable. When the temperature sensor 9 detects that the coolant temperature is too high, the controller not only closes the heat exchange solenoid valve 73, but also opens the liquid exchange solenoid valve 10. The high-temperature coolant is squeezed into the annular cavity 74 through the plunger assembly 8. The high-temperature coolant in the annular cavity 74 is then extracted by the suction assembly 20 for cooling and then re-injected into the annular cavity 74. This design ensures that the plunger assembly 8 is always in a highly efficient working state under normal motor operation, thereby extending the service life of the motor. This configuration ensures that when the motor is in operation, i.e., the rotor 5 rotates, the electric crankshaft 30 rotates synchronously. When the rotor 5 drives the crankshaft 30 to rotate synchronously, it simultaneously drives the polygonal block 40 to rotate eccentrically around the axis of the rotor 5. At the same time, the polygonal block 40 rotates relative to the crankshaft 30. This configuration ensures that when the polygonal block 40 rotates eccentrically around the axis of the rotor 5, it pushes several auxiliary piston assemblies 60 to slide back and forth within the hydraulic auxiliary tube 50. When the load on the motor suddenly increases, the speed of the rotor 5 drops sharply, which in turn causes the speed of the crankshaft 30 to decrease synchronously. This, in turn, reduces the speed of the eccentric rotation of the polygonal block 40. At the same time, the speed sensor 70 detects that the speed of the several auxiliary piston assemblies 60 sliding back and forth within the hydraulic auxiliary tube 50 decreases. During the entire process of the eccentric rotation of the polygonal block 40, under the action of the polygonal block 40, some auxiliary piston assemblies 60 move away from the center of the polygonal block 40, while other auxiliary piston assemblies 60 move closer to the center of the polygonal block 40. When the speed sensor 70 detects a decrease in the reciprocating speed of the several auxiliary piston assemblies 60 within the hydraulic auxiliary tube 50, the auxiliary solenoid valve 80 on the hydraulic auxiliary tube 50, which is slidably connected to the auxiliary piston assembly 60 moving away from the center of the polygonal block 40, closes, and the return solenoid valve 90 on the hydraulic auxiliary tube 50 opens. Simultaneously, the auxiliary solenoid valve 80 on the hydraulic auxiliary tube 50, which is slidably connected to the auxiliary piston assembly 60 moving closer to the center of the polygonal block 40, opens, and the hydraulic auxiliary... When the return solenoid valve 90 on pipe 50 is closed, and the suction assembly 20 squeezes coolant into the annular cavity 74, the hydraulic pressure in the annular cavity 74 increases. This causes the coolant in the annular cavity 74 to flow into the hydraulic assist pipe 50 through the connecting pipe 801 and the assist solenoid valve 80, pushing the assist plug assembly 60 in the hydraulic assist pipe 50 to move towards the center of the polygonal block 40, thereby generating a thrust on the polygonal block 40, which in turn assists the crankshaft 30, that is, assists the rotor 5. After the motor load changes, the flow of coolant pushes the auxiliary piston assembly 60 to move, thereby generating thrust on the polygonal block 40, ultimately assisting the crankshaft 30 and rotor 5. This design can provide additional assistance in a timely manner when the load increases, helping the motor maintain a stable speed, reducing the increase in motor heat generation due to load fluctuations, thus increasing the difficulty and efficiency of motor heat dissipation, and extending the service life of the motor. The coolant is not only used for motor heat dissipation, but also participates in the motor's assisting process as an assisting medium when the load changes, reducing the degree of heat generation increase caused by the increase in motor load. This allows the coolant to be used in multiple ways, reducing the need for additional equipment and lowering the complexity and cost of the system.

[0019] Reference Figures 3-9 As shown, the annular component 2 includes an annular cooling cavity body 21, on which a plurality of spiral channels 3 are provided. The plurality of spiral channels 3 are arranged in a ring around the axis of the annular cooling cavity body 21, and an annular sealing plate 22 is arranged coaxially with the annular cooling cavity body 21.

[0020] The annular sealing plate 22 is fixedly connected to the annular cooling chamber body 21. Several liquid inlets 23 are provided on the right side of the annular cooling chamber body 21. The several liquid inlets 23 are arranged in a ring around the annular cooling chamber body 21. The several liquid inlets 23 are respectively connected to several spiral channels 3.

[0021] The hydraulic assembly 7 includes a connecting ring body 77, which is fixedly connected to the inner cavity of the housing 1. Several cylindrical hydraulic chambers 71 are circumferentially formed on the connecting ring body 77 with the axis of the connecting ring body 77 as the reference. A cooling port 72 is formed on the left side of the connecting ring body 77. The cooling port 72 is connected to the spiral channel 3 through a pipe, a heat exchange solenoid valve 73 and a liquid inlet 23. A protective shell 78 is fixedly connected to the connecting ring body 77 coaxially.

[0022] Several plunger assemblies 8 each include a cooling piston 81, which is slidably connected in a cylindrical hydraulic chamber 71. A temperature sensor 9 is fixedly connected to the side of the cooling piston 81 facing the bottom of the cylindrical hydraulic chamber 71.

[0023] A push rod 82 is coaxially arranged with the cooling piston 81. The end of the push rod 82 away from the axis of the rotor 5 is fixedly connected to the cooling piston 81. A cooling spring 83 is sleeved on the push rod 82. A ball block 84 is fixedly connected to the end of the push rod 82 near the axis of the rotor 5. The ball block 84 abuts against the cam 6. When the rotor 5 drives the cam 6 to rotate, when the protruding part of the cam 6 rotates to the position of abutting against a ball block 84, the ball block 84 moves away from the axis of the cam 6, thereby driving the push rod 82 and the cooling piston 81 to move synchronously, so that the cooling piston 81 pushes the cylindrical hydraulic chamber 7. The coolant in the spiral channel 3 is squeezed out, the cooling spring 83 is compressed, and the coolant enters the spiral channel 3 through the cooling port 72, the pipe and the heat exchange solenoid valve 73 in sequence for cooling. When the concave part of the cam 6 rotates to the position of abutting the ball block 84, the cooling spring 83 returns to its original position, and at the same time, the push rod 82 and the cooling piston 81 move closer to the axis of the cam 6, so that the cooling piston 81 moves away from the bottom of the columnar hydraulic chamber 71, so that the coolant in the spiral channel 3 flows back into the columnar hydraulic chamber 71. During this process, the fluid exchange solenoid valve 10 is closed and the heat exchange solenoid valve 73 is opened. When the temperature sensor 9 detects that the temperature of the coolant flowing back into the cylindrical hydraulic chamber 71 exceeds the preset value, the heat exchange solenoid valve 73 closes and the fluid exchange solenoid valve 10 opens. Subsequently, when the protruding part of the cam 6 rotates to the position of abutting the ball block 84, the cooling piston 81 squeezes the coolant in the cylindrical hydraulic chamber 71 into the annular chamber 74 through the fluid exchange solenoid valve 10. Then, it is drawn out by the suction assembly 20 for cooling. After cooling is completed, the suction assembly 20 injects the coolant back into the annular chamber 74. Subsequently, when the concave part of the cam 6 rotates to the position of abutting the ball block 84, the cooling spring 83 resets, allowing the coolant to enter the cylindrical hydraulic chamber 71 through the fluid exchange solenoid valve 10. After that, the fluid exchange solenoid valve 10 closes and the heat exchange solenoid valve 73 opens.

[0024] The assisting assembly 60 includes an assisting piston 601, which is slidably connected inside the assisting tube 50. A speed sensor 70 is fixedly connected to the side of the assisting piston 601 adjacent to the bottom of the assisting tube 50 to monitor the moving speed of the assisting piston 601 inside the assisting tube 50. An assisting rod 602 is coaxially arranged with the assisting piston 601. One end of the assisting rod 602 away from the center of the polygonal block 40 is fixedly connected to the assisting piston 601. A slider 603 is fixedly connected to the end of the assisting rod 602 near the center of the polygonal block 40. The slider 603 is slidably connected to the polygonal block 40. A spring 604 is sleeved on the assisting rod 602, and a bellows 605 is sleeved on the outside of the spring 604.

[0025] The suction assembly 20 includes a liquid storage chamber 201, which is fixedly connected to the outer wall of the housing 1. A suction piston 202 is slidably connected inside the liquid storage chamber 201. A cylinder 203 is coaxially arranged with the liquid storage chamber 201 and is fixedly connected to the top of the liquid storage chamber 201. The output end of the cylinder 203 is fixedly connected to the suction piston 202. The liquid storage chamber 201 is connected to the annular cavity 74 through a hose. When the cylinder 203 contracts, the piston moves upward, allowing the high-temperature coolant in the annular cavity 74 to enter the liquid storage chamber 201 through the hose for cooling. After cooling is completed, the cylinder 203 extends, and the suction piston 202 draws the cooled coolant into the annular cavity 74 through the hose. When the speed sensor 70 detects a decrease in the reciprocating speed of the several auxiliary pistons 601 within the auxiliary tube 50, the auxiliary solenoid valve 80 on the auxiliary tube 50, which is slidably connected to the auxiliary piston 601 moving away from the center of the polygonal block 40, closes, and the return solenoid valve 90 on the auxiliary tube 50 opens. Simultaneously, the auxiliary solenoid valve 80 on the auxiliary tube 50, which is slidably connected to the auxiliary piston 601 moving closer to the center of the polygonal block 40, opens, and the return solenoid valve 90 on the auxiliary tube 50 closes. When cylinder 203 pushes suction piston 202 downward, it squeezes coolant in reservoir 201 into annular cavity 74, increasing hydraulic pressure in annular cavity 74. This causes coolant in annular cavity 74 to flow into auxiliary pipe 50 through connecting pipe 801 and auxiliary solenoid valve 80, pushing auxiliary piston 601 in auxiliary pipe 50 to move closer to the center of polygonal block 40, thereby generating thrust on polygonal block 40, which in turn assists crankshaft 30, i.e., assists rotor 5.
