Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heat dissipation motors, in particular to a heat dissipation motor shell and a control method thereof. BACKGROUND

[0002] In the current automobile manufacturing industry, electric power steering systems have become the core components for improving driving experience and vehicle handling, and are widely used in various vehicle models. Among them, the vehicle steering motor, as the power source of the system, needs to be installed in the chassis outside the driver's cabin. Therefore, how to efficiently cope with complex working environments is particularly important.

[0003] A vehicle steering motor assembly and manufacturing method disclosed in CN119171682A ensures high-precision manufacturing and stable assembly of the vehicle steering motor assembly through precise engraving, heating assembly, cooling fixation, cleaning and lubrication, and strict detection process. The sealing performance and structural strength of the motor are strengthened, which effectively copes with extreme weather and complex road conditions, accurately responds to steering demand, prolongs the service life, and solves the problems of insufficient sealing of existing vehicle motor assemblies, easy environmental erosion and insufficient structural strength.

[0004] Most of the electric power steering systems in current vehicles are installed in the chassis outside the driver's cabin, which can contact the natural airflow during vehicle driving to some extent. Therefore, relying on natural cooling is the most common form of heat dissipation in the steering assist system. At the same time, some high-performance vehicles also combine the form of heat dissipation holes to accelerate the heat dissipation of high-frequency motors to meet the basic driving needs. However, the pursuit of mechanical performance (including but not limited to the automotive field) is an endless process, and the concept of continuous improvement is indispensable for pursuing better and more durable mechanical performance:

[0005] Although the traditional automobile steering assist motor has basically met the needs of family transportation through the heat dissipation form of heat dissipation holes combined with natural cooling, but after a long time of driving, the heat exchange form relying on natural cooling is not enough to dissipate the heat accumulated by the motor during continuous work. The current advocacy of "please do not drive tiredly" does not only refer to people, but also to vehicles. After a long time of driving, the vehicle's main work system will inevitably overheat, which is not the best working condition. Therefore, experienced drivers will stop driving after a long time of driving (especially in hot summer), and the vehicle will rest, mainly to restore the vehicle to the best working temperature and state;

[0006] One reason why the car's optimal state is disrupted is that the heat exchange method relying on natural wind cooling is insufficient to dissipate the heat accumulated by the generator during continuous operation. Another reason is that the heat dissipation holes on the motor housing are generally small to prevent dust from entering. Although there is natural wind outside the housing, there is a lack of significant pressure difference between the inside and outside of the housing. Therefore, it is still difficult for the hot gas inside the housing to exchange with the outside through the small heat dissipation holes. In essence, the heat dissipation still relies on the heat conduction between the hot and cold air inside and outside the heat dissipation holes. In essence, it does not achieve a high heat dissipation effect of heat exchange. This drawback will become obvious in the form of overheating after the car has been driven for a long time.

[0007] To address the aforementioned issues, there is an urgent need for innovative designs based on the existing heat-dissipating motor housing and its control methods. Summary of the Invention

[0008] This invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. Specifically, the invention aims to provide a heat-dissipating motor housing and its control method. This addresses the issue raised in the background where the heat dissipation holes on the motor housing are typically small to prevent dust intrusion. Although there is natural airflow outside the housing, there is a lack of significant pressure difference between the inside and outside. Therefore, it is difficult for the hot gas inside the housing to exchange with the outside through the small heat dissipation holes. In essence, heat dissipation still relies on the heat conduction between the hot and cold air inside and outside the heat dissipation holes, which does not achieve a high heat dissipation effect through heat exchange. This drawback becomes significant in the form of overheating after the car has been running for a long time.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a heat-dissipating motor housing, comprising a motor housing and a motor assembly, further comprising induction cylinders equidistantly distributed outside the motor housing for sensing changes in the acceleration and deceleration state of a vehicle, an induction ball located inside the induction cylinder relying on inertial displacement, and spiral heat absorbers equidistantly distributed between the motor housing and the motor assembly for following the position change of the induction ball to realize the replacement of internal and external coolant. The motor housing has heat dissipation fins equidistantly distributed outside the induction cylinder, and the upper and lower ends of each spiral heat absorber penetrate through the side wall of the motor housing and are respectively connected to the upper and lower ends of the heat dissipation fins.

[0010] Preferably, the upper end of the induction tube is provided with an upper air intake pipe for only allowing cold air from the outside to enter and an upper air outlet pipe for only allowing cold air from inside the induction tube to enter the motor housing. The lower end of the induction tube is provided with a lower air intake pipe for only allowing hot air from inside the motor housing to enter the induction tube and a lower air outlet pipe for only allowing hot air from inside the induction tube to exit. Furthermore, the upper air intake pipe, upper air outlet pipe, lower air intake pipe, and lower air outlet pipe are all provided with a central ventilation chamber, and a one-way valve assembly is installed inside each of the central ventilation chambers.

[0011] Preferably, the one-way valve assembly includes an I-shaped plate, which is fixedly connected to the inner wall of the central venting chamber. A valve ball for sealing the central venting chamber is slidably sleeved on the outer wall of the central column of the I-shaped plate, and the air inlet end of the central venting chamber is provided with a spherical sidewall that fits the valve ball.

[0012] Preferably, a first spring is wound around the outer wall of the central column, and one end of the first spring is welded to the end of the I-shaped plate, and the other end of the first spring is fixed to the outer wall of the valve ball.

[0013] Preferably, the sensing ball is located at the center of the slide inside the sensing cylinder, and second springs are symmetrically arranged on both sides of the sensing ball within the slide.

[0014] Preferably, one end of the second spring is welded to the outer wall of the sensing ball, and the other end of the second spring is fixed to the inner wall of the sensing cylinder. The sensing ball is made of metal, and both the outer wall of the sensing ball and the inner wall of the slide are smoothed.

[0015] Preferably, the heat dissipation fins have a thin triangular cross-section, and the heat dissipation fins have a groove inside. A sensor plate is slidably disposed at the center of the groove. One end of a thin pull rope is symmetrically fixed at the upper and lower ends of the sensor plate, and the other end of the thin pull rope passes through the heat dissipation fins and the sensor cylinder and is fixedly connected to the center of the sensor ball.

[0016] Preferably, the internal spaces of the heat dissipation fins and the spiral heat absorber are filled with coolant, and sealing rings are provided at the points where the thin rope passes through the heat dissipation fins and the induction cylinder.

[0017] Preferably, a guide wheel assembly is installed on the outside of the heat dissipation fins and the induction cylinder, and the thin pull rope located outside the heat dissipation fins and the induction cylinder is guided twice at ninety degrees by the guide wheel assembly.

[0018] A control method for a heat-dissipating motor housing, the control method comprising the following steps:

[0019] S1. When the speed of the car changes, the induction ball, which maintains a horizontal and centered posture along the direction of the car's movement, will change its position in real time under its own inertia as the speed of the car changes, and will generate positive and negative pressures in the two sections separated by the induction ball inside the induction cylinder respectively.

[0020] S1-1. When positive pressure is generated in the upper part of the induction cylinder, the valve ball inside the upper air outlet pipe will be pushed open and the cold air in the upper space of the induction cylinder will be pushed into the motor housing. At the same time, when negative pressure is generated in the lower part of the induction cylinder, the valve ball inside the lower air intake pipe will be sucked open and the hot gas inside the motor housing will be sucked into the lower space of the induction cylinder.

[0021] S1-2. When positive pressure is generated in the lower section of the sensor cylinder, the valve ball inside the lower outlet pipe will be pushed open and the hot air in the lower space of the sensor cylinder will be output to the outside. At the same time, when negative pressure is generated in the upper section of the sensor cylinder, the valve ball inside the upper intake pipe will be sucked open and cold air from the outside will be drawn into the upper space of the sensor cylinder.

[0022] S2. In step S1, when the sensing ball slides down along the inner slide of the sensing cylinder, the sensing ball will be pulled up by the thin ropes on both sides, and the sensing plate will be moved up along the inner slide groove of the heat dissipation fins. The coolant in the upper part of the heat dissipation fins after being cooled by the high-speed flowing natural wind will be injected into the upper end of the spiral heat absorber. At the same time, the coolant inside the spiral heat absorber that has absorbed the heat of the motor assembly will enter the lower part of the heat dissipation fins under the push of the coolant in the upper part of the spiral heat absorber and the synchronous action of the negative pressure in the lower part of the heat dissipation fins to be cooled by natural wind.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] When the car's speed changes, the high-quality solid metal sensor ball, which maintains a horizontal and centered position along the car's direction of travel, will "sense" the dynamic changes in the car's speed in real time. Under its own inertia, the sensor ball will change position in real time with the dynamic speed of the car. When the sensor ball slides upward along the slide inside the sensor cylinder, it will compress the upper second spring and stretch the lower second spring. At the same time, it will create positive pressure in the upper space of the sensor cylinder and negative pressure in the lower half of the space. When positive pressure is generated, it will push open the valve ball inside the upper air outlet pipe and push the cold air in the upper space of the sensor cylinder into the motor housing. At the same time, when negative pressure is generated, it will suck open the valve ball inside the lower air intake pipe and draw the hot gas inside the motor housing into the lower space of the sensor cylinder.

[0025] Similarly, for the lower half of the sensor tube, when positive pressure is generated, it will push open the valve ball inside the lower exhaust pipe and output the hot air from the lower part of the sensor tube to the outside. At the same time, when negative pressure is generated, it will suck open the valve ball inside the upper intake pipe and draw in the cold air from the outside into the upper part of the sensor tube.

[0026] I. This invention utilizes the speed change of a car during driving and the inertia of the sensing ball to create a "breathing effect" between the upper and lower ends of the sensing cylinder, thereby creating a pressure difference between the inside and outside of the motor housing. This achieves a high heat dissipation method where "the amount of cold air that comes in is equal to the amount of hot air that comes out." Furthermore, the air drawn in from the outside passes through the sensing cylinder before entering the motor housing, avoiding the problem of dust intrusion that is easily caused by traditional heat dissipation hole methods.

[0027] Second, this invention utilizes spiral heat absorbers distributed at equal angles inside the motor housing to quickly absorb the heat generated during the operation of the motor components. It also utilizes the inertial movement of the induction ball caused by changes in vehicle speed to synchronously drive the induction plate to perform piston-like induction displacement within the heat dissipation fins, promoting natural exchange of coolant inside and outside the spiral heat absorber. This achieves rapid heat exchange between the inside and outside of the motor housing, and combined with the heat carrier exchange mechanism of the induction cylinder, it achieves an overall efficient cooling effect using natural wind. Under the same working time and frequency, it can significantly reduce the overheating of the vehicle after prolonged driving, and increase the duration of the vehicle's optimal condition under adverse environmental conditions (bumpy roads, frequent gear changes, frequent steering, and hot weather, etc.).

[0040] Please see Figures 1 to 10 The present invention provides a technical solution: a heat-dissipating motor housing, including a motor housing 1 and a motor assembly, and further including a sensor cylinder 2 equidistantly distributed outside the motor housing 1 for sensing changes in the acceleration and deceleration state of a vehicle, a sensor ball 4 located inside the sensor cylinder 2 and relying on inertial displacement, and a spiral heat absorber 8 equidistantly distributed between the motor housing 1 and the motor assembly for following the position change of the sensor ball 4 to realize the replacement of internal and external coolant. Heat dissipation fins 5 are equidistantly distributed outside the sensor cylinder 2 on the outside of the motor housing 1, and the upper and lower ends of each spiral heat absorber 8 penetrate through the side wall of the motor housing 1 and are respectively connected to the upper and lower ends of the heat dissipation fins 5.

[0041] The upper end of the induction tube 2 is provided with an upper air intake pipe 21 for only allowing cold air from the outside to enter and an upper air outlet pipe 22 for only allowing cold air from inside the induction tube 2 to enter the motor housing 1. The lower end of the induction tube 2 is provided with a lower air intake pipe 23 for only allowing hot air from inside the motor housing 1 to enter the induction tube 2 and a lower air outlet pipe 24 for only allowing hot air from inside the induction tube 2 to exit. The upper air intake pipe 21, the upper air outlet pipe 22, the lower air intake pipe 23 and the lower air outlet pipe 24 are all provided with a central air passage chamber. A one-way valve assembly is installed inside each central air passage chamber.

[0042] The one-way valve assembly includes an I-shaped plate 31, which is fixedly connected to the inner wall of the central venting chamber. A valve ball 3 for sealing the central venting chamber is slidably sleeved on the outer wall of the central column of the I-shaped plate 31. The air inlet end of the central venting chamber is provided with a spherical sidewall that fits the valve ball 3.

[0043] The outer wall of the central column is wound with a first spring 32, one end of the first spring 32 is welded to the end of the I-shaped plate 31, and the other end of the first spring 32 is fixed to the outer wall of the valve ball 3.

[0044] The sensing ball 4 is located at the center of the slide inside the sensing cylinder 2, and second springs 41 are symmetrically arranged on both sides of the sensing ball 4 inside the slide.

[0045] One end of the second spring 41 is welded to the outer wall of the sensing ball 4, and the other end of the second spring 41 is fixed to the inner wall of the sensing cylinder 2. The sensing ball 4 is made of metal, and both the outer wall of the sensing ball 4 and the inner wall of the slide are smoothed.

[0046] The heat dissipation fin 5 has a thin triangular cross section, and a sliding groove is provided inside the heat dissipation fin 5. A sensor plate 6 is slidably arranged at the center of the sliding groove. One end of a thin pull rope 7 is symmetrically fixed at the upper and lower ends of the sensor plate 6, and the other end of the thin pull rope 7 passes through the heat dissipation fin 5 and the sensor cylinder 2 and is fixedly connected to the center of the sensor ball 4.

[0047] The internal spaces of the heat dissipation fins 5 and the spiral heat absorber 8 are filled with coolant, and sealing rings are provided at the points where the thin rope 7 passes through the heat dissipation fins 5 and the induction cylinder 2.

[0048] The heat dissipation fins 5 and the induction cylinder 2 are equipped with guide wheel sets, and the thin pull rope 7 located outside the heat dissipation fins 5 and the induction cylinder 2 is guided by the guide wheel sets at two 90-degree angles.

[0049] A control method for a heat-dissipating motor housing, the control method comprising the following steps:

[0050] S1. When the speed of the car changes, the sensor ball 4, which maintains a horizontal and centered posture along the direction of the car's movement, will change its position in real time under its own inertia as the speed of the car changes, and will generate positive and negative pressures in the two sections separated by the sensor ball 4 inside the sensor cylinder 2 respectively.

[0051] S1-1. When positive pressure is generated in the upper section of the induction cylinder 2, the valve ball 3 inside the upper air outlet pipe 22 will be pushed open and the cold air in the upper space of the induction cylinder 2 will be pushed into the motor housing 1. At the same time, when negative pressure is generated in the lower section of the induction cylinder 2, the valve ball 3 inside the lower air intake pipe 23 will be sucked open and the hot gas inside the motor housing 1 will be sucked into the lower space of the induction cylinder 2.

[0052] S1-2. When a positive pressure is generated in the lower section of the induction cylinder 2, the valve ball 3 inside the lower air outlet pipe 24 will be pushed open and the hot air in the lower space of the induction cylinder 2 will be output to the outside. At the same time, when a negative pressure is generated in the upper section of the induction cylinder 2, the valve ball 3 inside the upper air intake pipe 21 will be sucked open and the cold air from the outside will be drawn into the upper space of the induction cylinder 2.

[0053] S2. In step S1, when the sensing ball 4 slides down along the inner slide of the sensing cylinder 2, the sensing ball 4 will be pulled by the thin ropes 7 on both sides to drive the sensing plate 6 to slide up along the inner slide groove of the heat dissipation fin 5. The coolant in the upper part of the heat dissipation fin 5 after being cooled by the high-speed flowing natural wind will be injected into the upper end of the spiral heat absorber 8. At the same time, the coolant inside the spiral heat absorber 8 that has absorbed the heat of the motor assembly will enter the lower part of the heat dissipation fin 5 under the push of the coolant at the upper end of the spiral heat absorber 8 and the synchronous action of the negative pressure in the lower part of the heat dissipation fin 5 to be cooled by the natural wind.

[0054] Working principle: Power steering systems in automobiles not only work when the car is turning, but also when the car encounters bumps or uneven surfaces. The power steering motor assists in correcting the driver's direction. Some advanced EPS systems even make minor adjustments while driving straight to counteract steering wheel deviation caused by uneven road surfaces or changes in vehicle dynamics. Therefore, even when driving straight, the power steering system operates at a high frequency, and... Figure 1 As shown, the power steering system of most cars is located flat under the driver's cab with the motor perpendicular to the two wheel axles and facing forward.

[0055] When driving a car, the driver needs to maintain a high level of concentration. The driver constantly adjusts the direction and throttle based on the road surface and surrounding conditions to regulate the car's speed and position. It's difficult for a car to maintain a constant speed; therefore, speed changes (accelerator and throttle) are the most frequent driving operations throughout the entire process. When the car's speed changes, such as... Figure 7 and Figure 8 The high-quality solid metal induction ball 4, which maintains a horizontal and centered posture along the direction of the car's movement, will "sensor" the dynamic changes in the car's speed in real time. Under its own inertia, the induction ball 4 will change its position in real time with the dynamic speed of the car, and make the induction ball 4 slide back and forth along the central axis of the vehicle in the sliding track inside the induction cylinder 2.

[0056] 1. Assuming that the sensing ball 4 slides upward along the internal slide of the sensing cylinder 2 (the terms "up" and "down" mentioned in this article refer to the planar orientation shown in the attached diagram, not the accurate real-time orientation), the sensing ball 4 will compress the upper second spring 41 and stretch the lower second spring 41, simultaneously creating positive pressure in the upper part of the sensing cylinder 2 and negative pressure in the lower half of the sensing cylinder 2:

[0057] When positive pressure is generated, it will push open the valve ball 3 inside the upper air outlet pipe 22 and push the cold air in the upper space of the induction cylinder 2 into the motor housing 1. At the same time, when negative pressure is generated, it will suck open the valve ball 3 inside the lower air intake pipe 23 and suck the hot gas inside the motor housing 1 into the lower space of the induction cylinder 2.

[0058] 2. When the sensing ball 4 slides downward along the internal slide of the sensing cylinder 2, the sensing ball 4 will compress the lower second spring 41 and stretch the upper second spring 41, simultaneously creating negative pressure in the upper part of the sensing cylinder 2 and positive pressure in the lower part of the sensing cylinder 2:

[0059] When positive pressure is generated, it will push open the valve ball 3 inside the lower exhaust pipe 24 and output the hot air in the lower space of the induction cylinder 2 to the outside. At the same time, when negative pressure is generated, it will suck open the valve ball 3 inside the upper suction pipe 21 and draw in the cold air from the outside into the upper space of the induction cylinder 2 (the exhaust port of the lower exhaust pipe 24 in the attached figure is provided with a flared mouth facing the heat dissipation fins 5, and the airflow that is quickly discharged from the lower exhaust pipe 24 can be used to accelerate the cooling of the coolant inside the heat dissipation fins 5).

[0060] The above-mentioned method utilizes the speed change of the car during driving and the inertia of the induction ball 4 to create a "breathing effect" between the upper and lower ends of the induction cylinder 2, thereby creating a pressure difference between the inside and outside of the motor housing 1. This achieves a high heat dissipation method where "the amount of cold air that comes in is equal to the amount of hot air that comes out." Furthermore, the air drawn in from the outside passes through the induction cylinder 2 before entering the interior of the motor housing 1, avoiding the problem of dust intrusion that is easily caused by traditional heat dissipation holes (when the car is not driven, traditional motor heat dissipation holes are directly connected to the outside, and dust can easily directly enter the motor interior. However, in this invention, when the car is not driven, the air vents are connected to the outside through the induction cylinder 2, so even if dust intrudes, it can only enter the induction cylinder 2 and will not directly intrude into the motor).

[0061] Thirdly, as the induction ball 4 slides upward along the inner slide of the induction cylinder 2, the induction ball 4 will be pulled by the thin pull ropes 7 on both sides to drive the induction plate 6 to slide downward along the inner slide groove of the heat dissipation fin 5, and inject the coolant in the lower half of the heat dissipation fin 5 after being cooled by the high-speed flowing natural wind into the lower end of the spiral heat absorber 8. At the same time, the coolant inside the spiral heat absorber 8 that has absorbed the heat of the motor assembly will enter the upper half of the heat dissipation fin 5 under the push of the coolant at the lower end of the spiral heat absorber 8 and the synchronous action of the negative pressure in the upper half of the heat dissipation fin 5 to be cooled by the natural wind.

[0062] Similarly, when the induction ball 4 slides down along the inner slide of the induction cylinder 2, the induction ball 4 will be pulled by the thin pull ropes 7 on both sides to drive the induction plate 6 to slide up along the inner slide groove of the heat dissipation fin 5. The coolant in the upper part of the heat dissipation fin 5 after being cooled by the high-speed flowing natural wind will be injected into the upper end of the spiral heat absorber 8. At the same time, the coolant inside the spiral heat absorber 8 that has absorbed the heat of the motor assembly will enter the lower part of the heat dissipation fin 5 under the push of the coolant at the upper end of the spiral heat absorber 8 and the synchronous action of the negative pressure in the lower part of the heat dissipation fin 5 to be cooled by the natural wind.

[0063] In this cycle, the spiral heat absorbers 8, which are distributed at equal angles inside the motor housing 1, can quickly absorb the heat generated during the operation of the motor components. The inertial movement of the induction ball 4 caused by the change in vehicle speed synchronously drives the induction plate 6 to perform piston-like induction displacement inside the heat dissipation fins 5, thereby promoting the natural exchange of coolant inside and outside the spiral heat absorbers 8. This achieves rapid heat exchange between the inside and outside of the motor housing 1. Combined with the heat carrier exchange of the induction cylinder 2, the overall heat dissipation method achieves the effect of efficient natural wind cooling. Under the same working time and working frequency, it can significantly reduce the overheating of the vehicle after long-term driving and increase the duration of the vehicle's optimal condition under adverse environmental conditions (bumpy road surface, frequent gear changes, frequent steering, and hot weather, etc.).

[0064] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
