Description

Technical Field

[0001] This invention relates to the field of motor equipment, and more particularly to a motor with an integrated heat dissipation structure in its housing. Background Technology

[0002] In the field of electric vehicle equipment applications, the requirements for motor performance and stability are extremely high. Among them, heat dissipation has always been a key bottleneck restricting the long-term efficient operation of motors. Traditional motors mostly use a single heat dissipation structure, which has limited heat dissipation efficiency and is difficult to adapt to the high-load and long-term working requirements. The internal installation space of electric vehicles is cramped, and the large amount of heat generated by the motor during operation is easy to accumulate around it and cannot be dissipated quickly. This not only leads to a decrease in motor output power and an increase in energy consumption, but may also cause problems such as accelerated component aging and insulation performance degradation. In severe cases, it may even cause safety failures. At the same time, the air intake filter of the heat dissipation end of traditional motors is easily clogged by dust and impurities accumulated in the driving environment, resulting in poor airflow for heat dissipation, further deteriorating the heat dissipation effect, increasing the frequency and cost of equipment maintenance. In addition, as the core heat-generating component of the motor, the stator assembly is difficult to dissipate heat in an all-round and rapid manner using traditional heat dissipation methods, resulting in frequent local overheating and affecting the overall service life and operational reliability of the motor. Therefore, we propose a motor with an integrated heat dissipation structure in the outer shell to solve the above-mentioned problems. Summary of the Invention

A return flow shroud is fixedly connected to the inner side of the air guide shroud. A filter screen is installed in the middle of the return flow shroud. A uniformly distributed reserved opening is opened in the middle of the air guide shroud.

[0005] Preferably, the outer side of the middle part of the air guide shroud near the partition plate is fixedly connected to a uniformly distributed guide pipe, and the end of the guide pipe away from the air guide shroud passes through the adjacent partition plate.

[0006] Preferably, a mounting bracket is fixedly connected to one side of the partition plate that is close to it, and the mounting bracket is penetrated by the stator assembly. The fixing plate is disposed on the outside of the mounting bracket.

[0007] Preferably, a connecting ring is fitted on both sides of the outer periphery of the mounting bracket, and the connecting ring is provided with evenly distributed protrusions on the outer periphery of the connecting ring. A evenly distributed connecting pipe is fixedly connected between the connecting rings.

[0008] Preferably, the connecting pipes are all disposed between the stator assemblies, the sidewalls of the connecting pipes and the connecting rings are both in contact with the stator assemblies, the connecting pipes and the connecting rings are connected, and coolant is disposed inside the connecting pipes and the connecting rings.

[0009] Preferably, both sides of the inner wall of the rotating sleeve are fixedly connected with uniformly distributed pressure columns, each pressure column corresponding to the connecting ring and fitting against the outer circumferential surface of the connecting ring.

[0010] Preferably, the rotating sleeve has evenly distributed openings on both sides of its outer periphery, and the partition plate near the fixed grid housing has evenly distributed connecting openings on its outer side in the middle, all of which connect to the space between the mounting bracket and the rotating sleeve.

[0011] Preferably, the cooling fan blades are disposed between the filter screen and the air guide shroud, both the filter screen and the air guide shroud are rotatably connected by a rotating shaft, and the filter screen is attached to one side of the air vent.

[0012] Preferably, a sealing ring is fixedly installed at the middle of the end of the front cover away from the fixed grid housing, and the sealing ring is sleeved on the outer circumference of the rotating shaft.

[0013] Preferably, one end of the rotating shaft is an output end used to connect to the driven component, and the other end of the rotating shaft is rotatably connected to the rear end cover via a bearing.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. To address the issue that motors operating under continuous high loads during electric vehicle operation are prone to poor airflow due to dust accumulation on the intake filter, affecting heat dissipation efficiency and equipment stability, this invention addresses this problem. The rotating shaft synchronously drives the cooling fan blades, drawing in external air through the vent to form a cooling airflow. The filter effectively filters dust and impurities from the air, preventing them from entering the motor and causing component wear or blockage. Simultaneously, the curved design of the air guide shroud guides some of the cooling airflow back to meet the return shroud, thus impacting the filter in reverse and promptly removing dust adhering to it. This prevents dust accumulation from affecting subsequent airflow, ensuring long-term stable motor operation, reducing the frequency of maintenance due to filter blockage, and meeting the long-term usage needs of electric vehicles in complex driving environments.

[0016] 2. Addressing the issue of limited internal space in electric vehicles, where heat generated by the motor tends to accumulate, leading to reduced heat dissipation, especially after prolonged driving, where high temperatures can negatively impact motor performance and even pose safety hazards, this invention addresses this problem. Part of the cooling airflow generated by the cooling fan blades is precisely guided through a guide pipe to the cooling fins on the outer periphery of the rotating sleeve. This ensures efficient heat exchange through full contact between the airflow and the fins, quickly removing the heat transferred from the motor. Simultaneously, the airflow acting on the cooling fins drives the rotating sleeve to rotate. The rotating sleeve and fins actively disturb the hot air around the motor, breaking the static environment of heat accumulation, accelerating the diffusion of hot air and the replenishment of cool air, significantly improving heat dissipation efficiency. This design perfectly suits the cramped internal space of electric vehicles, effectively controlling temperature even during prolonged high-load operation, ensuring stable motor output power, and preventing power reduction or equipment damage due to overheating.

[0017] 3. Addressing the problem that traditional heat dissipation methods struggle to achieve comprehensive and rapid heat dissipation of the stator assembly, often resulting in localized overheating, this invention utilizes a connecting pipe and a connecting ring to form a heat dissipation circuit surrounding the stator assembly. Both pipes and rings are tightly fitted to the stator assembly, allowing the internal coolant to directly and fully absorb the heat generated by the stator assembly. Simultaneously, as the rotating sleeve is driven to rotate by the cooling airflow, the pressure column inside rotates synchronously and continuously presses against the protrusions on the connecting ring. This mechanical pressure promotes rapid circulation of the coolant within the connecting pipe and ring. During this flow, the coolant efficiently absorbs heat from the stator assembly and rapidly conducts it to the pipe wall, dissipating it into the surrounding airflow. This achieves a highly efficient cycle of "heat absorption, heat conduction, and heat dissipation," significantly improving the heat dissipation speed and uniformity of the stator assembly. This prevents damage to the motor caused by localized overheating, extends the motor's lifespan, and ensures stable performance under high-load conditions.

[0018] 4. Addressing the problem that traditional cooling airflow methods struggle to penetrate the core heat-generating areas due to the complex internal structure of motors, resulting in insufficient heat dissipation and affecting overall cooling performance, this invention addresses this issue. Part of the cooling airflow enters the motor through a pre-reserved opening on the air guide shroud. It then smoothly enters the space between the mounting bracket and the rotating sleeve via a connecting port on the partition plate. The stator assembly, connecting pipe, and connecting ring within this space are directly exposed to the airflow, allowing for full contact with these core heat-generating components and the cooling structure, forming comprehensive convective cooling. The airflow after heat exchange is finally discharged from the motor through an opening on the rotating sleeve. The entire airflow path covers the key heat-generating areas inside the motor, achieving a complete cooling process of "external air intake, internal penetration, comprehensive heat exchange, and rapid exhaust," significantly improving the comprehensiveness and effectiveness of cooling. This further ensures temperature uniformity among the motor's internal components, avoids equipment failures caused by localized cooling dead zones, and provides dual protection for the long-term stable operation of the motor.

Detailed Implementation

[0026] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0027] like Figures 1-6 The motor shown has an integrated heat dissipation structure in its casing. It includes a front cover 101, a fixed grille housing 108 fixedly connected to the rear side of the front cover 101, a rear cover 105 fixedly connected to the end of the fixed grille housing 108 away from the front cover 101, partition plates 118 fixedly connected to the middle of both ends of the fixed grille housing 108, limit rings 127 fixedly connected to the adjacent sides of the partition plates 118, rotating rings 122 rotatably connected to the inner side of each limit ring 127, and rotating sleeves 107 rotatably connected to the inner side of the fixed grille housing 108 via the limit rings 127 and rotating rings 122. The rotating rings 122 are fixedly connected to both sides of the outer periphery of the rotating sleeves 107. The outer periphery of the rotating sleeve 107 is fixedly connected with evenly distributed heat dissipation fins 104. The front cover 101 and the middle of the partition plate 118 are both connected to a rotating shaft 103. One end of the rotating shaft 103 is the output end for connecting the driven component. The other end of the rotating shaft 103 is rotatably connected to the rear cover 105 through a bearing. A sealing ring 102 is fixedly installed in the middle of the end of the front cover 101 away from the fixed grid housing 108. The sealing ring 102 is sleeved on the outer periphery of the rotating shaft 103. A rotor assembly 115 is installed in the middle of the outer periphery of the rotating shaft 103. Evenly distributed fixed plates 119 are fixedly connected between the partition plates 118. A stator assembly 120 is installed on each of the fixed plates 119.

[0028] Furthermore, in practical implementation, within the electric vehicle structure, the motor enables the driving operation. Specifically, the terminal block installed on the front cover 101 connects the motor to the electric vehicle's power supply and control components. During operation, after power is supplied, electromagnetic induction causes the rotor assembly 115 in the motor to rotate, causing the shaft 103 to rotate accordingly. The shaft 103 connects relevant reduction gears and driven components, completing the required driving operation for the electric vehicle. Under the operation of the cooling fan blades 117, some of the cooling airflow enters the guide pipe 1. Inside the 13, the airflow is guided by the guide pipe 113, so that the airflow comes into contact with the heat dissipation fins 104 on the outer periphery of the rotating sleeve 107 to achieve auxiliary heat dissipation. At the same time, the airflow will drive the rotating sleeve 107 to rotate through the heat dissipation fins 104. The rotation of the rotating sleeve 107 and the heat dissipation fins 104 can directly disturb the airflow around the motor, thereby preventing the accumulation of heat in the surrounding air due to the motor's heat dissipation. It is suitable for heat dissipation when the motor is working for a long time, and is more suitable for the long-term operation of electric vehicles and the confined internal installation space.

[0029] Among them, a mounting bracket 126 is fixedly connected to one side of the partition plate 118 that is close to it. The mounting bracket 126 is penetrated by the stator assembly 120. The fixing plate 119 is set on the outside of the mounting bracket 126. A connecting ring 124 is sleeved on both sides of the outer periphery of the mounting bracket 126. The connecting ring 124 is provided with evenly distributed protrusions 123 on the outer periphery of the connecting ring 124. Evenly distributed connecting pipes 121 are fixedly connected between the connecting rings 124. The connecting pipes 121 are all set between the stator assemblies 120. The sidewalls of the connecting pipes 121 and the connecting rings 124 are in contact with the stator assembly 120. The connecting pipes 121 and the connecting rings 124 are connected. Coolant is provided inside the connecting pipes 121 and the connecting rings 124.

[0030] Furthermore, in specific implementation, the stator assembly 120 is surrounded by the connecting pipe 121 and connecting ring 124 inside the motor, which enables sufficient heat dissipation of the stator assembly 120. During operation, some of the cooling airflow passes through the reserved opening 116 and comes into contact with the partition plate 118 on that side. The connecting opening 114 on the partition plate 118 facilitates the entry of the cooling airflow. It comes into full contact with the connecting pipe 121 and connecting ring 124 between the mounting bracket 126 and the rotating sleeve 107, as well as between the stator assembly 120 and the mounting bracket 126 and the rotating sleeve 107. Finally, the cooling airflow is discharged through the opening 106 on the rotating sleeve 107. The cooling airflow enables sufficient heat dissipation of the contacting stator assembly 120, connecting pipe 121, and connecting ring 124, thereby significantly improving the heat dissipation effect of the stator assembly 120, which is beneficial for practical use.

[0031] Among them, a heat dissipation fan blade 117 is fixedly connected to the outer periphery of the tail end of the rotating shaft 103, an air guide shroud 111 is installed on the inner side of the rear end cover 105, a return shroud 112 is fixedly connected to the inner side of the air guide shroud 111, a filter screen 110 is installed in the middle of the return shroud 112, the heat dissipation fan blade 117 is located between the filter screen 110 and the air guide shroud 111, the filter screen 110 and the air guide shroud 111 are both penetrated by the rotating shaft 103 and rotatably connected to the rotating shaft 103, and the filter screen 110 is attached to one side of the vent 109.

[0032] Furthermore, in specific implementation, when the rotating shaft 103 rotates, it will drive the cooling fan blades 117 fixed at the tail to rotate. When the cooling fan blades 117 rotate, they will draw in external air through the vent 109 to form a cooling airflow. The airflow can be filtered by the filter screen 110. During this process, the arc surface of the air guide shroud 111 can guide the cooling airflow, so that some of the cooling airflow can flow back and meet the return shroud 112. The return shroud 112 can guide the airflow to contact the filter screen 110, thereby achieving backflow of the filter screen 110 and preventing dust accumulation at the filter screen 110 from affecting the subsequent airflow, which is beneficial to the long-term use of the motor.

[0033] The air guide shroud 111 has evenly distributed reserved openings 116 in the middle. The air guide shroud 111 is fixedly connected to the outer side of the middle part of the end near the partition plate 118 with evenly distributed guide pipes 113. The end of the guide pipes 113 away from the air guide shroud 111 passes through the adjacent partition plate 118. The rotating sleeve 107 has evenly distributed openings 106 on both sides of its outer periphery. The partition plate 118 near the fixed grid housing 108 has evenly distributed connecting openings 114 on the outer side of the middle part. The connecting openings 114 connect the space between the mounting bracket 126 and the rotating sleeve 107. The inner side wall of the rotating sleeve 107 is fixedly connected to two parts with evenly distributed pressure columns 125. The pressure columns 125 correspond to the connecting ring 124 and are in contact with the outer periphery of the connecting ring 124.

[0034] Furthermore, in specific implementation, when the rotating sleeve 107 is driven to rotate, the pressure column 125 fixed inside the rotating sleeve 107 will rotate accordingly. The pressure column 125 can squeeze the protrusion 123 on the connecting ring 124. The rotation of the rotating sleeve 107 will achieve continuous squeezing of the protrusion 123. The squeezing of the protrusion 123 will enable the flow of internal coolant. The rapid flow of coolant can accelerate the absorption of heat on the stator assembly 120 and the dissipation of its own heat, thereby achieving rapid heat dissipation of the motor interior and the stator assembly 120.

[0035] Working principle:

[0036] In the structure of an electric vehicle, the motor drives the vehicle. Specifically, the terminal block installed on the front cover 101 connects the motor to the power supply and control components. During operation, after power is supplied, electromagnetic induction causes the rotor assembly 115 in the motor to rotate, causing the shaft 103 to rotate accordingly. The shaft 103 connects to relevant reduction gears and driven components, completing the required driving operation for the electric vehicle. Specifically, when the shaft 103 rotates, it drives the cooling fan blades 117 fixed at the rear to rotate. As the cooling fan blades 117 rotate, they draw in external air through the vent 109, forming a cooling airflow. The filter 110 filters the incoming air. During the process, the curved surface of the air guide shroud 111 guides the cooling airflow, allowing some of the cooling airflow to flow back and meet the return shroud 112. The return shroud 112 guides the airflow to contact the filter screen 110, thereby achieving backflushing of the filter screen 110 and preventing dust accumulation on the filter screen 110 from affecting subsequent airflow, which is beneficial to the long-term use of the motor. Under the operation of the cooling fan blades 117, some cooling airflow will enter the guide pipe 113. The guide pipe 113 guides the cooling airflow, allowing it to contact the cooling fins 104 on the outer periphery of the rotating sleeve 107 for auxiliary cooling. At the same time, the cooling airflow will drive the rotating sleeve 107 to rotate through the cooling fins 104. The rotation of the rotating sleeve 107 and the heat dissipation fins 104 directly disturbs the airflow around the motor, thus preventing heat buildup in the surrounding air due to motor heat dissipation. This is suitable for heat dissipation during long-term motor operation and is more suitable for the long-term operation and confined internal installation space of electric vehicles. In use, the stator assembly 120 is surrounded by the connecting pipe 121 and connecting ring 124 inside the motor, which can achieve sufficient heat dissipation for the stator assembly 120. During operation, when the rotating sleeve 107 is driven to rotate, the pressure column 125 fixed inside the rotating sleeve 107 will rotate accordingly. The pressure column 125 can squeeze the protrusion 123 on the connecting ring 124. The rotation of the rotating sleeve 107 will achieve continuous squeezing of the protrusion 123. The cooling system works by squeezing the protrusion 123 to allow the internal coolant to flow. This rapid flow of coolant accelerates the absorption and dissipation of heat from the stator assembly 120, resulting in rapid heat dissipation from the motor interior and the stator assembly 120, which is beneficial for practical use. Simultaneously, some of the cooling airflow passes through the reserved opening 116 and contacts the partition plate 118 on that side. The connecting opening 114 on the partition plate 118 facilitates the entry of the cooling airflow. It then makes full contact with the connecting pipe 121 and connecting ring 124 between the mounting bracket 126 and the rotating sleeve 107, and between the stator assembly 120 and the mounting bracket 126 and the rotating sleeve 107. Finally, the cooling airflow exits through the opening 106 on the rotating sleeve 107.The cooling airflow effectively dissipates heat from the contacting stator assembly 120, connecting pipe 121, and connecting ring 124, significantly improving the heat dissipation effect of the stator assembly 120 and benefiting practical applications.
