Description

Technical Field

[0001] The present invention relates to the technical field of wheel hub motors, and in particular to a high-efficiency heat dissipation wheel hub motor. Background Art

[0002] As a new type of drive technology, the wheel hub motor plays an extremely important role in the field of modern transportation, especially in electric vehicles and hybrid vehicles. It integrates the power source directly into the wheel hub, simplifies the vehicle's transmission system, reduces the loss in the energy transfer process, and significantly improves the vehicle's energy efficiency. At the same time, this distributed drive method gives the vehicle better handling performance, can achieve more precise torque control, and improve the vehicle's driving stability and safety. In addition, the wheel hub motor also brings greater flexibility to the vehicle's design, facilitates the layout optimization and multi-functional expansion of the vehicle, and strongly promotes the innovation and development of automotive technology.

[0003] Existing wheel hub motors are usually composed of core components such as the motor body, stator, rotor, and bearings. When working, current is passed into the stator winding to generate a rotating magnetic field, which drives the rotor to rotate, thereby driving the wheel to rotate. The motor body is generally wrapped in a shell to protect the internal components.

[0004] However, existing hub motors have certain defects. In terms of heat dissipation, since they mainly rely on natural wind for heat dissipation, when the vehicle is in high-speed operation, the heat generated by the motor increases sharply, and the heat dissipation speed of natural wind is far from meeting the demand. Heat accumulates rapidly inside the motor, causing the motor temperature to continue to rise, which will seriously affect the performance of the motor, causing the motor's output power to drop and its efficiency to decrease. When exposed to high temperature for a long time, the insulating material inside the motor will accelerate aging, the winding resistance will increase, and even cause motor short circuits and other faults, shortening the service life of the motor, increasing the safety risks of vehicle operation, and seriously restricting the reliability and stability of the hub motor in high-performance vehicle applications. Therefore, an efficient heat dissipation hub motor is proposed to solve the above problems. Summary of the invention

[0005] In order to make up for the above shortcomings, the present invention provides a high-efficiency heat dissipation hub motor, which aims to improve the problem that the equipment usually uses natural wind for heat dissipation. When the equipment runs at high speed, the internal heat is difficult to be dissipated in time, which may cause damage to the equipment.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Reference Figure 1 and Figure 2 , an embodiment provided by the present invention: an efficient heat dissipation wheel hub motor, comprising a wheel hub motor body 1, characterized in that: a cover plate 8 is provided on one side of the wheel hub motor body 1, a heat dissipation component is provided on the outer wall of the wheel hub motor body 1, and a quick release component is provided on one side of the cover plate 8;

[0035] The heat dissipation assembly includes a plurality of arc-shaped guide plates 3, which are located on one side of the wheel hub motor body 1. The outer wall of each arc-shaped guide plate 3 is provided with an angled guide plate, which is used to guide the wind direction, ensure smooth air circulation, optimize the heat dissipation effect, reduce heat accumulation, and improve the motor operation efficiency. A fixing ring 2 is fixedly connected to one side of the wheel hub motor body 1, and the inner wall of the fixing ring 2 is fixedly connected to the outer wall of the arc-shaped guide plate 3, which plays a role in stabilizing and fixing the arc-shaped guide plate 3 to avoid loosening or displacement during high-speed operation. A connecting ring 7 is fixedly connected to one side of the arc-shaped guide plate 3, and the connecting ring 7 helps to connect the arc-shaped guide plate 3 with other structural parts. Firm connection improves the stability of the overall assembly. A connecting plate 4 is fixedly connected between two adjacent arc-shaped guide plates 3. The function of the connecting plate 4 is to maintain the relative position of the arc-shaped guide plates 3 and ensure the reasonable distribution of the airflow path. A connecting block 5 is fixedly connected to one side of each connecting plate 4. The connecting block 5 further enhances the stability of the connecting plate 4 and provides support for the installation of the venturi tube 6. A venturi tube 6 is fixedly connected inside each connecting block 5. The venturi tube 6 has a large structure on both sides and a small structure in the middle, which is used to accelerate the air flow rate. By reducing the cross-sectional area in the middle of the pipe, the air is prompted to flow at a higher speed, thereby effectively improving the heat dissipation effect and accelerating the heat discharge;

[0036] Specifically, during the heat dissipation process of the equipment, the rotational force of the hub motor body 1 is effectively utilized, and the arc guide plate 3 is driven to rotate synchronously, thereby guiding the external air flow. When the arc guide plate 3 rotates, it uses its specially designed outer wall bevel to introduce external air into the outer surface of the hub motor body 1, and adjusts the airflow direction to ensure that the air can evenly cover the outer wall of the hub motor body 1. This process improves the efficiency of air flow, thereby enhancing the heat dissipation effect. At the same time, the rotation of the arc guide plate 3 not only affects the air flow, but also cooperates with the rotation of the venturi tube 6. The venturi tube 6 is an important airflow acceleration device. The larger opening on the side effectively guides the external air into the interior of the venturi tube 6. The middle part of the venturi tube 6 is a narrow area. When the airflow passes through this area, the air pressure will drop rapidly, resulting in an increase in flow rate. Subsequently, at the larger opening on the other side of the venturi tube 6, the airflow is re-expanded and accelerated, forming a strong airflow, which pushes the air to continue to flow toward the outer wall of the hub motor body 1. The venturi effect is utilized, and a higher flow rate and lower pressure are generated when the airflow passes through the venturi tube 6, further improving the speed and efficiency of air flow. The increase in air flow rate improves the contact efficiency between the air and the hub motor body 1, thereby enhancing the heat dissipation effect. This aerodynamic structure not only effectively improves the heat dissipation performance, but also optimizes the working environment and performance stability of the overall equipment. The heat dissipation effect of the equipment has been significantly improved, ensuring that the hub motor body 1 can still maintain good temperature control performance under high-load working conditions.

[0037] Reference Figure 3-Figure 5The quick-release assembly includes a plurality of card balls 18, which provide fixing and detachable functions to ensure the stability of the assembly and facilitate disassembly. The card ball 18 is located on one side of the cover plate 8, which is used to close and protect the internal structure. A fixing ring 2 10 is fixedly connected to the inner wall of the hub motor body 1, and the fixing ring 2 10 is used to fix and support related parts. A plurality of outer shells 2 17 are fixedly connected inside the fixing ring 2 10, and the outer shell 2 17 is used to protect the internal components and provide an installation platform. A plurality of outer shells 15 are fixedly connected inside the cover plate 8, and the outer shell 15 is used to protect the internal components and connect them to the outside world. A fixing ring 3 16 is fixedly connected to the inner wall of each outer shell 15, and the fixing ring 3 16 is used to provide support and positioning. The inner wall of each fixing ring 3 16 is slidably connected with Connecting shaft 14, the function of connecting shaft 14 is to transmit rotational motion and bear axial force, one end of each connecting shaft 14 is fixedly connected with a truncated cone block 19, the function of the truncated cone block 19 is to ensure the connection between the connecting shaft 14 and other components and provide positioning, the other end of each connecting shaft 14 is fixedly connected with a connecting column 12, the function of the connecting column 12 is to connect other parts and transmit mechanical force, the outer wall of each connecting shaft 14 is provided with a spring 13, the function of the spring 13 is to provide elastic force, ensure the normal movement of parts and play a buffering role, one end of each spring 13 is fixedly connected to the outer wall of fixing ring three 16, fixing ring three 16 provides a stable installation position for spring 13, the other end of each spring 13 is fixedly connected to the outer wall of connecting column 12, connecting column 12 provides another fixed point for spring 13. The outer wall of each connecting column 12 is fixedly connected with a connecting disk 11. The function of the connecting disk 11 is to provide connection and fixation to ensure stable connection between components. A connecting ring 2 9 is fixedly connected to one side of the connecting disk 11. The function of the connecting ring 2 9 is to provide fixation and connection to ensure stable connection between external equipment or components and internal structures. The outer wall of the truncated cone block 19 fits with the outer wall of the card ball 18. This design ensures that the card ball 18 can effectively clamp the truncated cone block 19 to ensure the fixation of the component. The card ball 18 is slidably connected to the inner sides of the shell 15. The sliding of the card ball 18 on the inner side of the shell 15 makes it easy to disassemble the component. The card ball 18 is engaged with the inner wall of the shell 2 17. The engagement of the card ball 18 with the shell 2 17 ensures the locking and stability of the components.

[0038] Specifically, when performing maintenance inside the equipment, it is necessary to remove the cover plate 8 for in-depth inspection and maintenance of the equipment. The disassembly process first requires pressing the connecting ring 2 9. While applying downward pressure, the connecting ring 2 9 drives the connecting column 12 to move through the connecting disk 11 inside it. The movement of the connecting column 12 will cause it to squeeze the spring 13, thereby compressing the spring 13. At the same time, the connecting shaft 14 will generate a force to push the truncated cone block 19 to move along a specific trajectory. As the truncated cone block 19 moves, it will interact with the card ball 18, causing the card ball 18 to detach from its original position. Specifically, the truncated cone block 19 pushes the card ball 18 to detach from the outer wall of the card ball 18. In this process, the card ball 18 gradually moves out of the original fixed position, allowing the cover plate 8 to be pulled outward. At the same time, the angled portion of the inner wall of the outer shell 2 17 will push the card ball 18 to shrink inward, further releasing the connection between the card ball 18 and the hub motor body 1. At this time, the cover plate 8 is successfully separated from the hub motor body 1, thereby realizing the disassembly operation of the cover plate 8, making the repair and maintenance of the equipment more convenient, simplifying the disassembly and assembly process, and improving the efficiency of equipment maintenance. When the repair and maintenance work is completed, the spring 13 will push the cone block 19 to return to its original position due to its restored rebound force, thereby re-squeezing the card ball 18 to the angled surface of the inner wall of the shell 17 to ensure that the card ball 18 is firmly fixed in the appropriate position. This process ensures the stable installation of the cover plate 8, and then the connection between the hub motor body 1 and the cover plate 8 can be re-established, ensuring the stability and safety of each component of the equipment during use.

[0039] Working principle: In the process of heat dissipation of the equipment, the rotational force of the hub motor body 1 is used to drive the arc guide plate 3 to rotate synchronously. The arc guide plate 3 attracts external air to the outer wall of the hub motor body 1 while rotating, and uses the bevel of the outer wall of the arc guide plate 3 to guide the airflow to ensure that the air can blow to the outer wall of the hub motor body 1. The arc guide plate 3 also drives the Venturi tube 6 to rotate while rotating, and uses the large opening on one side of the Venturi tube 6 to conduct external air to the inside of the Venturi tube 6. The narrow area in the middle of the Venturi tube 6 is used to reduce the pressure of the nearby air, so that the air flow rate is enhanced, and then the larger opening on the other side is used to conduct the air to the outer wall of the hub motor body 1, thereby increasing the air circulation speed and enhancing the heat dissipation of the equipment. Thermal effect, when it is necessary to disassemble the cover plate 8 and perform maintenance on the inside of the equipment, press the connecting ring 2 9. While moving, the connecting ring 2 9 will drive the connecting column 12 to squeeze the spring 13 through the connecting disk 11, and push the truncated cone block 19 to move through the connecting shaft 14, so that the truncated cone block 19 is moved out from the outer wall of the card ball 18. At this time, pull the cover plate 8 outward, and the inner wall angle of the shell 2 17 pushes the card ball 18 to shrink inward, so that the card ball 18 can be separated from the hub motor body 1, and the cover plate 8 can be disassembled, which improves the portability of equipment maintenance. After the maintenance is completed, the rebound force of the spring 13 is used to push the truncated cone block 19 to squeeze the card ball 18, so that the card ball 18 is stuck on the inner wall angle surface of the shell 2 17, so as to achieve the installation and fixation of the hub motor body 1 and the cover plate 8.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
