DETAILED DESCRIPTION

[0037] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings 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 should fall within the scope of protection of the present invention.

[0038] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0039] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0040] Example 1, please refer to Figure 1-Figure 5, a motor housing that is easy to assemble, comprising a stator 6, a stator rear cover 5 and a stator front cover 8 are respectively inserted at the two ends of the stator 6, a housing body 12 is injection-molded between the outer surfaces of the stator 6, the stator rear cover 5 and the stator front cover 8, and the housing body (12) has an air duct, and the stator front cover 8 is provided with a plurality of stator rear cover holes 801; by inserting the stator rear cover 5 and the stator front cover 8 at the two ends of the stator 6, and injecting the housing body 12 between the outer surfaces of the stator 6, the stator rear cover 5 and the stator front cover 8 to achieve assembly, it is not necessary to use a large number of screws and other fasteners, which facilitates the assembly of the motor and improves the production efficiency; since it is not necessary to use a large number of screws and other fasteners, the application reduces the production cost and reduces the risk of motor performance degradation or damage caused by loose fasteners.

[0041] The operator only needs to plug the stator rear cover 5 and the stator front cover 8 at both ends of the stator 6 and then perform injection molding to complete the assembly of the casing body 12 without the need for tedious screw tightening operations, thereby greatly improving production efficiency and reducing labor costs and time costs.

[0042] Further, such as Figure 3 and Figure 5 As shown, a rotor 7 is arranged in the stator 6, one end of the rotor 7 passes through the stator front cover 8 and the casing body 12 and is connected to the fan blade 11. The rotor 7 drives the fan blade 11 to rotate to accelerate the circulation of the surrounding air of the present application. The motor will generate a lot of heat during operation. If the heat cannot be dissipated in time, the temperature of the motor will increase, affecting the performance and life of the motor. The rotation of the fan blade 11 accelerates the air circulation, which can quickly take away the heat generated by the operation of the motor. Through the rapid flow of air, the heat inside the motor can be dissipated in time to avoid overheating of the motor, thereby extending the service life of the motor, ensuring the stability of the motor performance, and improving the working efficiency and reliability of the motor.

[0043] Further, such as Figure 3 As shown, a front elastic body 9 is provided on the side of the stator front cover 8 close to the fan blades 11, and the outer surface of the rotor 7 passes through the front elastic body 9. When the motor is running, the rotor 7 will have certain vibrations and relative movements. The front elastic body 9 plays a role of buffering and isolation to prevent the rotor 7 from directly rubbing against the stator front cover 8. If the rotor 7 and the stator front cover 8 are in direct contact and friction, long-term operation will cause surface wear of both, affecting their accuracy and service life. The setting of the front elastic body 9 reduces this wear, prolongs the service life of the rotor 7 and the stator front cover 8, ensures the overall performance and stability of the motor, and reduces the frequency of maintenance and replacement of parts.

[0044] Further, such as Figure 3As shown, the outer surface of the rotor 7 is sleeved with a front bearing 10, and the front bearing 10 is in contact with a side of the front elastic body 9 away from the stator 6. The front bearing 10 provides stable support for the rotor 7, so that the rotor 7 remains stable during rotation and reduces shaking and deviation. When the motor is running, the high-speed rotation of the rotor 7 requires a stable support point. The front bearing 10 plays this important role. It can effectively reduce the vibration of the rotor 7 caused by unbalanced force or other factors, ensure the normal operation of the motor, and improve the working efficiency and performance of the motor. The stable operation of the rotor 7 can also reduce energy loss and improve the energy efficiency ratio of the motor.

[0045] Further, such as Figure 3 As shown, the other end of the rotor 7 passes through the stator back cover 5, and the end of the stator back cover 5 away from the stator 6 is installed with a rear elastic body 4. The outer surface of the rotor 7 passes through the rear elastic body 4, which is similar to the function of the front elastic body 9. The rear elastic body 4 plays a role of buffering and isolation between the rotor 7 and the stator back cover 5. When the motor is running, the other end of the rotor 7 will also have a certain amount of movement. The rear elastic body 4 can alleviate the impact and friction of the rotor 7 on the stator back cover 5, prevent wear of both, and ensure the integrity and service life of the rotor 7 and the stator back cover 5. This helps to maintain the overall structural stability of the motor and reduce the performance degradation and failure risk of the motor due to component wear. The front elastic body 9 and the rear elastic body 4 can both be made of rubber.

[0046] Further, such as Figure 3 As shown, a rear bearing 3 is sleeved on one end of the rotor 7 away from the fan blades 11, and the rear bearing 3 is connected to the side of the rear elastic body 4 away from the stator rear cover 5. The rear bearing 3 can support the rotor 7 to improve the stability of the rotor 7 during operation. The rear bearing 3 further provides support for the rotor 7, and works together with the front bearing 10 to ensure the stability of the rotor 7 during the operation of the motor. The two bearings work together like a stable frame to firmly fix the rotor 7 in a suitable position, so that it can remain stable under high-speed rotation and various working conditions. This not only improves the overall performance and reliability of the motor, but also reduces the vibration and noise caused by the instability of the rotor 7, and improves the working environment of the motor.

[0047] Further, such as Figure 3 As shown, the stator back cover 5 is provided with a plurality of stator back cover holes 501, and the stator 6 has a plurality of welding legs 601, one end of each of the welding legs 601 respectively passes through the plurality of stator back cover holes 501, and the arrangement of the welding legs 601 facilitates the connection of the stator 6 circuits, and the arrangement of the stator back cover holes 501 not only facilitates the routing of the welding legs 601, but also facilitates heat dissipation.

[0048] Further, such as Figure 1 and Figure 2As shown, a PCB board 2 is connected between one ends of a plurality of welding feet 601, a power plug 1 is welded on the PCB board 2, the PCB board 2 is located outside the casing body 12, and the power plug 1 is welded on the PCB board 2, so that the connection between the motor and the power supply becomes simple and quick, and fast power-on is achieved. In actual use, the user only needs to insert the power plug 1 into the corresponding power socket to power the motor, which improves the convenience of using the motor. Moreover, the PCB board 2 and the power plug 1 are located outside the casing body 12, which is convenient for maintenance and replacement. When the PCB board 2 fails or needs to be upgraded, the operator can operate it conveniently without disassembling the internal structure of the motor, thereby reducing the maintenance cost and difficulty. At the same time, the PCB board 2 is located outside, which is conducive to heat dissipation, avoiding the influence of internal heat accumulation on its performance, and further improving the reliability and stability of the motor.

[0049] Example 2, please refer to Figure 6 The casing body 12 includes an outer shell 121 and an inner shell 122 located inside the outer shell 121. A plurality of air duct guide vanes 123 are arranged between the inner shell 122 and the air duct guide vanes 123. The air duct is located between the inner shell 122 and the outer shell 121. The air duct guide vanes 123 play a role in changing the wind direction and guiding the air. There are gaps between the plurality of air duct guide vanes 123. A first bearing hole 124 is arranged at one end of the inner shell 122. The rear bearing 3 is installed in the first bearing hole 124. A second bearing hole is arranged at the other end of the inner shell 122. The front bearing 10 is installed in the second bearing hole. The stator rear cover 5, the stator 6 and the stator front cover 8 are all arranged in the inner shell 122, and the fan blades 11 are located in the outer shell 121. When the fan blades 11 rotate, they can drive air to flow inside the inner shell 122, quickly take away the heat generated by the internal components, achieve effective heat dissipation inside the motor, reduce the motor temperature, and extend the life of the motor. At the same time, the fan blades 11 accelerate the speed of air circulation between the outer shell 121 and the inner shell 122, which can not only dissipate the heat inside the motor to the external environment, but also dissipate heat to other surrounding objects, thereby increasing the functionality and practicality of the motor.

[0050] Example 3, please refer to Figure 7-Figure 12 , a method for manufacturing a motor housing that is easy to assemble, for manufacturing a motor housing that is easy to assemble, comprising: performing injection molding using an injection mold;

[0051] The injection mold includes a first mold 13 and a second mold 14. The first mold 13 includes a first mold base 131. A first mold core 132 is disposed in the first mold base 131. The second mold 14 includes a second mold base 141 located at one side of the first mold base 131. An inner mold body 142 is disposed in the second mold base 141. A second mold core 143 is disposed in the middle of the inner mold body 142.

[0052] The method also includes the following steps: installing the stator front cover 8 at the front end of the stator 6, installing the stator rear cover 5 at the rear end of the stator 6, placing the stator 6 with the stator rear cover 5 and the stator front cover 8 installed into the first mold core 132 by the robot, then closing the first mold 13 with the second mold 14, using the injection molding machine to inject molding from the injection port 145 between the second mold core 143, the first mold core 132 and the stator 6 to form the housing body 12, opening the mold after the injection molding is completed, and taking out the molded product by the robot; realizing automated production, improving production efficiency and product quality, using robots for operation, and the entire production process is highly efficient. The high degree of automation reduces the uncertainty and error caused by human intervention. The robot can operate according to the preset program and accuracy, accurately put the stator 6 with the end cover installed into the mold, and quickly take out the product after the injection molding is completed, which improves the accuracy and consistency of production. The injection molding process is integrated, from mold closing to injection molding to mold opening and taking out the parts. The whole process is coherent and efficient, and the casing body can be quickly formed, which greatly improves production efficiency. At the same time, automated production reduces the impact of human factors on product quality, ensures the quality stability of each product, and improves the product qualification rate and overall quality level.

[0053] Further, such as Figure 8 , Fig.10 and Fig.11 As shown, the first mold 13 also includes a support base 133 installed on the side of the first mold base 131 away from the second mold base 141, a fixed plate 134 is arranged in the support base 133, a plurality of support rods 136 are connected between the fixed plate 134 and the first mold base 131, and a movable plate 135 is sleeved between the outer surfaces of the plurality of support rods 136, and the movable plate 135 can move on the outer surfaces of the support rods 136. The arrangement of the support base 133, the fixed plate 134 and the support rods 136 provides a solid support structure for the first mold 13, so that the first mold 13 can withstand various forces such as injection pressure and remain stable during operation. During the injection molding process, the pressure applied by the injection molding machine is relatively large. If the mold structure is unstable, the mold may be deformed or damaged, affecting the injection molding accuracy and product quality. This stable structural design ensures the reliability and accuracy of the mold during long-term use, ensures the smooth progress of the injection molding process, extends the service life of the mold, and reduces the cost of mold maintenance and replacement.

[0054] Further, such as Figure 8As shown, the outer surface of the support rod 136 is sleeved with a spring 137 located between the movable plate 135 and the first mold base 131, and a ejector rod 138 is provided on the side of the movable plate 135 close to the first mold base 131. One end of the ejector rod 138 passes through the first mold base 131 and extends into the first mold core 132. During the movement of the movable plate 135, the ejector rod 138 can push out the casing body 12 injection-molded in the first mold core 132, which is convenient for material discharge. This design improves production efficiency and reduces production cycle. At the same time, the smooth demolding process also ensures the surface quality and dimensional accuracy of the product, reduces the defective rate, and improves the overall quality of the product.

[0055] Further, such as Figure 8-Figure 11 As shown, a plurality of guide holes 139 are provided on the first mold base 131, and a plurality of guide rods 146 are provided on the side of the connecting base 144 close to the second mold base 141. One end of the guide rod 146 passes through the second mold base 141 and is plugged into the guide hole 139. The guide hole 139 and the guide rod 146 cooperate with each other to guide during the mold closing process of the first mold 13 and the second mold 14, so that the mold closing of the first mold 13 and the second mold 14 is more accurate. Accurate mold closing ensures the accuracy of the injection space and avoids problems such as product size deviation and uneven wall thickness caused by mold closing deviation.

[0056] Further, such as Fig.11 As shown, a mounting seat 147 is connected between the inner mold body 142 and the second mold base 141. The mounting seat 147 and the second mold core 143 can be connected together through the mounting seat 147 and bolts. The mounting seat 147 can be used to transport materials to the second mold core 143 during the injection molding process.

[0057] Further, such as Fig.12 As shown, the injection molded product is taken out and put into the assembly line, then the rotor 7 is installed in the stator 6, and then the rear elastomer 4 and the front elastomer 9 are assembled, and then the rear bearing 3 and the front bearing 10 are respectively installed between the two ends of the casing body 12 and the rotor 7, the fan blades 11 are assembled, and the PCB board 2 and the power plug 1 are welded, and finally the test is carried out.
