Description

Technical Field

[0001] The invention relates to the technical field of motors, and in particular to a washing pump motor. Background Art

[0002] In a high-pressure washing pump, the output shaft of a motor is often used to drive the impeller to rotate, so that the impeller rotates in the liquid storage chamber of the pump body and the liquid in the liquid storage chamber is sprayed out from the nozzle.

[0003] As the power component in the high-pressure washing pump, the motor is an important factor affecting the liquid spraying effect and the cost of the entire high-pressure washing pump; the existing motor structure generally includes an upper electronic control part and a lower output part; the circuit board of the electronic control part is generally fixed to the casing by fasteners. During the long-term operation of the motor, the fasteners often become loose, causing the circuit board to shake in the casing, resulting in poor stability of the upper end of the motor; the output part lacks an anti-jumping structure for the rotor, and axial jumps often occur during operation, and the impeller jumps, resulting in poor stability of the lower end of the motor; when the stability of any of the upper and lower ends of the motor deteriorates, the motor will shake, thereby affecting the liquid spraying effect;

[0004] In addition, the rotors of existing motors mostly use heavy annular strong magnetic tiles that are sleeved on the rotor shaft. This structure makes the rotor's own weight larger and consumes more energy during rotation, making it less efficient. The annular strong magnetic tiles themselves are relatively expensive. During production, if the annular strong magnetic tiles are too tightly fitted to the rotor shaft, the tiles are easily crushed. If they are too loosely fitted, the two are prone to slipping. Therefore, production is difficult and the defective rate is high, ultimately leading to a higher cost for the entire motor. How to keep the motor efficient and stable while reducing production costs is a problem that technicians are committed to solving. Summary of the invention

[0037] The embodiments of the present invention are further described below in conjunction with the accompanying drawings.

[0038] See also Figure 1-11 A washing pump motor shown includes a shielding shell 1, an electric control component 2 arranged at the upper end of the shielding shell 1, and an output component 3 arranged at the lower end of the shielding shell 1;

[0039] The shielding shell 1 includes an electric control housing 11 disposed at the upper end and an output housing 12 disposed at the lower end; the inner wall of the electric control housing 11 is provided with a plurality of bidirectional fixing mechanisms 114 integrally formed with the electric control housing 11, and the electric control component 2 is fixed in the electric control housing 11 via the bidirectional fixing mechanisms 114;

[0040] The output assembly 3 includes a stator 31 and a rotor 32 disposed in the output housing 12; the rotor 32 includes a rotor shaft 321, a magnetic conductive portion 322 sleeved on the rotor shaft 321, a plurality of strong magnetic tiles 323 spaced apart along the circumferential direction of the magnetic conductive portion 322, double-position fixing portions 324 disposed at both ends of the magnetic conductive portion 322, and an anti-jump mechanism 325 disposed along the axial direction of the rotor shaft 321;

[0041] The magnetic conductive part 322 is formed by stacking a plurality of silicon steel sheets so as to enhance the magnetic field formed by the plurality of strong magnetic tiles 323; the double-position fixing part 324 includes an axial edging 3241 and a radial edging 3242; the strong magnetic tiles 323 are reinforced on the magnetic conductive part 322 via the axial edging 3241, and the plurality of silicon steel sheets stacked to form the magnetic conductive part 322 are reinforced via the radial edging 3242;

[0042] The anti-jumping mechanism 325 includes a rotor shaft anti-jumping structure 3251 and a magnetic conductive part anti-jumping structure 3252; the rotor shaft anti-jumping structure 3251 is arranged at at least one end of the output housing 12 to prevent the axial movement of the rotor shaft 321; the magnetic conductive part anti-jumping structure 3252 is arranged at both ends of the magnetic conductive part 322 to prevent the axial movement of the magnetic conductive part 322 in the output housing 12.

[0043] Compared with the prior art, the shielding shell 1 of the present invention includes an electric control housing 11 and an output housing 12, wherein the inner wall of the electric control housing 11 is provided with a bidirectional fixing mechanism 114 integrally formed therewith, and the bidirectional fixing mechanism 114 can avoid loosening like conventional fasteners when fixing the electric control component 2, thereby making the upper end of the motor more stable; the rotor 32 of the output component 3 includes a rotor shaft 321, a magnetic conductive part 322, a strong magnetic tile 323, a double-position fixing part 324 and an anti-jumping mechanism 325; the rotor shaft 321 is restricted by a rotor shaft anti-jumping structure 3251, and the magnetic conductive part 322 is restricted by a magnetic conductive part anti-jumping structure 3252, so that the axial jumping space of the rotor 32 is reduced, thereby making the lower end of the motor more stable; when the stability of the upper and lower ends is improved, The overall stability of the motor is better, and the liquid spraying effect is better; the multiple strong magnetic tiles 323 of the output component 3 are arranged at intervals along the circumferential direction of the magnetic conductive part 322, and are fixed with the radial edging 3242 of the double-position fixing part 324. Compared with the annular magnetic tiles sleeved on the rotor shaft, they are not easy to break or slip during production, thereby reducing the defective rate during production and reducing the manufacturing cost; and the strong magnetic tiles 323 reduce the high-cost strong magnetic dosage compared to the annular magnetic tiles, saving the overall cost of the motor, reducing the dead weight of the rotor, and reducing the energy loss caused by the excessive dead weight of the rotor when rotating. The magnetic conductive part 322 is composed of multiple silicon steel sheets stacked to supplement the magnetic field strength that reduces the loss of strong magnetic dosage, thereby reducing the manufacturing cost while maintaining a high output efficiency.

[0044] Please continue reading Figure 2 , Figure 3 , Figure 4 , Figure 5 The electric control housing 11 includes an end cover 111 and an upper cover 112 arranged on the end cover 111; the end cover 111 includes a first concave shell 1111 formed toward the rotor 32; the output housing 12 includes a lower cover 121 and a second concave shell 1211 formed away from the rotor 32; the stator 31, the first concave shell 1111 and the second concave shell 1211 form a rotor accommodating space 113 for accommodating the rotor 32.

[0045] Specifically, the first concave shell 1111 is formed by the end cover 111, and the second concave shell 1211 is formed by the lower cover 121. Both are not independently configured. Under this configuration, the cost of independently producing the concave shell is reduced, and the installation process of the concave shell is avoided, so that the overall manufacturing cost of the motor is lower, and the one-piece molded concave shell can avoid loosening caused by motor vibration. The first concave shell 1111 makes the upper end structure of the motor more stable, and the second concave shell 1211 makes the lower end of the motor more stable; in addition, the stator 31, the first concave shell 1111 and the second concave shell 1211 form a rotor accommodating space 113 for accommodating the rotor 32, which provides a basis for the subsequent realization of the anti-jumping function of the rotor 32.

[0046] Please continue reading Figure 4 , Figure 5 , Figure 6 The rotor shaft anti-jumping structure 3251 includes a ball bearing 32511 and an oil-containing bearing 32512 respectively arranged at both ends of the rotor shaft 321; the outer ring of the ball bearing 32511 is arranged to be closely matched with the second concave shell 1211, and the inner ring is arranged to be closely matched with the outer wall of the rotor shaft 321, so as to reduce the axial jump of the rotor shaft 321; the oil-containing bearing 32512 is arranged to be fixed to the first concave shell 1111; the end cover 111 has at least one positioning step for positioning the end cover 111 and the lower cover 121 to maintain the concentricity of the two.

[0047] Specifically, in this embodiment, the outer ring of the ball bearing 32511 is tightly matched with the second concave shell 1211 and is fixed, and the inner ring of the ball bearing 32511 is tightly matched with the outer wall of the rotor shaft 321. When the rotor shaft 321 rotates, the inner and outer rings of the ball bearing 32511 can only rotate relative to each other and cannot move up and down, thereby limiting the up and down movement of the rotor shaft 321; the oil-containing bearing 32512 is tightly matched with the inner wall of the first concave shell 1111. When the rotor shaft 321 rotates, its upper end rotates in the oil-containing bearing 32512. Since the ball bearing 32511 is already provided at one end of the rotor shaft 321, the rotor shaft 321 has already played a role in preventing the rotor shaft 321 from jumping. Therefore, setting the other end as a lower-cost oil-containing bearing 32512 is a lower-cost option for the entire motor.

[0048] It is understandable that when the motor power is large and the speed is high, the oil-containing bearing 32512 at the other end of the rotor shaft 321 can also be replaced by a ball bearing 32511.

[0049] Please continue reading Figure 4 , Figure 5 , wherein the rotor accommodating space 113 includes a first axial space 1131, a second axial space 1132, a third axial space 1133, and a fourth axial space 1134 which are arranged in sequence from bottom to top; the magnetic conductive part anti-jumping structure 3252 includes a first filling part 32521 and a second filling part 32522; the ball bearing 32511 is arranged in the first axial space 1131; the first filling part 32521 is arranged in the second axial space 1132; the magnetic conductive part 322 is arranged in the third axial space 1133; and the second filling part 32522 is arranged in the fourth axial space 1134.

[0050] It can be understood that during the high-speed rotation of the rotor 32, the rotor shaft 321, the magnetic conductive part 322, and the strong magnetic tile 323 installed on the magnetic conductive part 322 all have a certain degree of jumping; based on the two parts of jumping, the rotor accommodating space 113 is divided into a first axial space 1131, a second axial space 1132, a third axial space 1133, and a fourth axial space 1134, wherein the ball bearing 32511 is arranged in the first axial space 1131, and the magnetic conductive part 322 is arranged in the third axial space 1134. Space 1133, and the second axial space 1132 and the fourth axial space 1134 are left to leave room for the magnetic conductive part 322 and the strong magnetic tiles 323 installed on the magnetic conductive part 322 to move. When the first filling part 32521 is set in the second axial space 1132 and the second filling part 32522 is set in the fourth axial space 1134, the axial positions of these two spaces are filled, thereby avoiding the magnetic conductive part 322 and the strong magnetic tiles 323 installed on the magnetic conductive part 322 and other components to move.

[0051] Please read further Figure 4 , Figure 5 , wherein the first filling portion 32521 is a circular hard clamp ring; the upper end surface of the first filling portion 32521 abuts against the lower end surface of the magnetic conductive portion 322; the lower end surface of the first filling portion 32521 abuts against the upper end surface of the inner ring of the ball bearing 32511;

[0052] The second filling portion 32522 is a disc-shaped soft gasket; the lower end surface of the second filling portion 32522 contacts the upper end surface of the magnetic conductive portion 322 ; the upper end surface of the second filling portion 32522 contacts the upper end surface of the first concave shell 1111 .

[0053] It can be understood that, since the lower end of the rotor shaft 321 is provided with a ball bearing 32511, and the inner ring of the ball bearing 32511 rotates synchronously with the rotor shaft 321, it is more preferred to set the first gap portion 32521 as a circular hard clamp ring. The circular hard clamp ring can press against the lower end surface of the magnetic conductive portion 322 and the upper end surface of the inner ring of the ball bearing 32511 to fill the second gap portion 32522, and can rotate with the two without affecting the transmission between the two. It is an oil-containing bearing 32512, and the oil-containing bearing 32512 is arranged in the first concave shell 1111, that is, when the magnetic conductive part 322 rotates, its upper end surface may generate friction with the bottom wall of the first concave shell 1111, resulting in reduced motor efficiency; when the second filling part 32522 is a disc-shaped soft gasket, the soft gasket can reduce the friction with the magnetic conductive part 322 or the bottom wall of the first concave shell 1111 by adding lubricant or using oil-free self-lubricating material, so as to fill the fourth axial space 1134 without affecting the efficiency of the motor.

[0054] Please continue reading Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , wherein the strong magnetic tile 323 is arranged to have a fan-shaped cross section; the magnetic conductive portion 322 includes a central axis 3221, a through hole 3222 arranged through the central axis 3221, a plurality of segmented sections 3223 arranged circumferentially along the outer wall of the central axis 3221, and a magnetic tile installation area 3224 surrounded by the central axis 3221 and two adjacent segmented sections 3223; the strong magnetic tile 323 is arranged in the magnetic tile installation area 3224; the lower end of the rotor shaft 321 has at least one step.

[0055] Under this setting, the amount of strong magnetic material used in the motor is reduced compared to the annular strong magnetic tiles. The reduced part is the part filled with the segment 3223. The magnetic field strength lost due to the reduction of strong magnetic material can be compensated by the magnetic conductive part 322 composed of multiple silicon steel sheets. The use of high-cost strong magnetic materials is reduced without affecting the magnetic field strength, and the weight of the entire rotor 32 is reduced, thereby reducing the energy consumed by the rotor 32 on its own weight when it rotates, thereby improving the overall efficiency of the motor.

[0056] For further information, please refer to Figure 7 , Figure 8 The lower end of the rotor shaft 321 is configured to have at least one step. Under this configuration, the rotor shaft 321 can be pressed into the through hole 3222 by the joint force of the lower end surface of the rotor shaft 321 and the step, thereby reducing the bending of the rotor shaft 321 and the scratches on the outer surface of the rotor shaft 321 entering the through hole 3222, so that the rotor shaft 321 drives the magnetic conductive part 322 to rotate with higher stability and concentricity, and the entire motor is more stable.

[0057] Please continue reading Fig.10 , wherein the strong magnetic tile 323 includes an inner arc surface 3231, an outer arc surface 3232 and two side surfaces 3233; the radial edge 3242 applies a force toward the central axis 3221 to the outer arc surface 3232; the inner arc surface 3231 is in contact with the outer wall of the central axis 3221, and the two side surfaces 3233 are respectively in contact with the side surfaces of two adjacent segments 3223.

[0058] It can be understood that during production, the strong magnetic tile 323 is attached to the magnetic conductive part 322 from the side of the magnetic conductive part 322, and the non-magnetic conductive part 322 is forcibly pressed into the inner hole of the circular strong magnetic tile. This arrangement reduces the probability of crushing the strong magnetic tile 323 when the strong magnetic tile 323 and the magnetic conductive part 322 are installed, thereby reducing production losses and reducing manufacturing costs. In addition, when the outer arc surface 3232 is tightly wrapped by the radial edge 3242, the force of the inner arc surface 3231 is shared to the central axis 3221, and the force of the two side surfaces 3233 is respectively shared to the sides of the two adjacent segments 3223, so that the pressure of the entire strong magnetic tile 323 is shared, and it is not easy to break during production and use, which further reduces the manufacturing cost.

[0059] Please continue reading Figure 3 , Figure 4 , wherein the bidirectional fixing mechanism 114 includes a plurality of bottom lifting portions 1141 and a plurality of top buckling portions 1142; the plurality of bottom lifting portions 1141 are arranged on the upper end surface of the end cover 111; the plurality of top buckling portions 1142 are arranged on the side wall inside the upper cover 112;

[0060] The end cover 111 has a first buckle groove 1112 arranged along the circumference of the edge, and the upper cover 112 includes a first fastener 1121 arranged at the bottom of the side wall; when the first fastener 1121 is riveted and fixed to the first buckle groove 1112, the bottom lifting part 1141 and the top buckling part 1142 fix the electronic control component 2 from the bottom and the top respectively.

[0061] Specifically, multiple bottom lifting parts 1141 are integrally formed on the upper end surface of the end cover 111 by bending, casting, welding and other processes, and the top snap-fitting part 1142 is integrally formed on the side wall inside the upper cover 112 by riveting and other processes. Both will not loosen like fasteners during the vibration of the motor; during production, the electric control component 2 is set on multiple bottom lifting parts 1141, and when the first fastener 1121 is riveted and fixed to the first snap groove 1112, the top snap-fitting part 1142 presses the top of the electric control component 2, so that the electric control component 2 is subjected to force from the bottom and the top respectively, thereby avoiding instability of the upper end of the motor due to loosening of the electric control component 2.

[0062] Please continue reading Figure 2 , Figure 3 , wherein the end cover 111 further has a plurality of second buckle grooves 1113 arranged through, and the output housing 12 includes a second buckle 122 arranged at the upper end of the side wall; when the second buckle grooves 1113 and the second buckle 122 are riveted and fixed, the axial clearance in the rotor accommodating space 113 is reduced.

[0063] Please continue reading Figure 1 , Figure 2 , wherein the electric control component 2 includes a connector 21; the connector 21 passes through the top of the upper cover 112; and the rotor shaft 321 passes through the bottom of the second concave shell 1211.

[0064] Under this arrangement, the entire motor has only two relatively small openings, namely, the outlet of the connector 21 and the outlet of the rotor shaft 321 , thereby making the shielding effect of the motor better and the anti-interference performance better.

[0065] It is worth mentioning that in the present embodiment, the connector 21 includes a negative electrode connector and two positive electrode connectors, wherein the negative electrode connector is connected to the upper cover 112 to ensure that the shell is grounded, thereby further increasing the shielding effect; it is understandable that in other embodiments, the multiple connectors may also include a dedicated grounding connector, which can also ensure that the shell is grounded when the grounding connector is connected to the upper cover 112.

[0066] The above description is only for the best embodiment of the present invention, but it should not be understood as limiting the claims. The present invention is not limited to the above embodiments, and its specific structure is allowed to be changed. All changes made within the scope of protection of the independent claims of the present invention are within the scope of protection of the present invention.
