Description

Technical Field

[0001] The present invention relates to the technical field of motors, and in particular to an integrated axial flux motor. Background Art

[0002] An axial flux motor is a motor in which the magnetic flux is distributed along the axial direction of the motor. Compared with traditional radial flux motors (magnetic flux is distributed radially), its structure is flatter and more compact, and it has unique advantages and a wide range of application scenarios.

[0003] The flat design of the axial flux motor saves axial space and is suitable for equipment with limited installation space, such as electric vehicle wheels, robot joints, etc.

[0004] The axial flux motors at the robot's joints need to drive the robot's limbs to reciprocate, enabling rapid start and stop, as well as forward and reverse motion. To extend the robot's service life, the axial flux motors are typically encased. To make the robot relatively flexible and proportionate, the size of the robot's joints is relatively limited. The axial flux motors need to be highly aligned with the robot's joints, generating heat. Optimizing the heat dissipation of the axial flux motors is difficult in order to maintain the robot's flexibility and joint state, minimizing the impact on the robot. Summary of the Invention

[0005] The object of the present invention is to provide an integrated axial flux motor to solve the problems raised in the above background technology.

[0006] To solve the above technical problems, the present invention provides the following technical solution: an integrated axial flux motor, comprising a main body, the main body comprising a housing and a rotating shaft extending therefrom, the housing having a liquid storage chamber for carrying coolant at one end facing the rotating shaft, a heat dissipation component mounted on the liquid storage chamber, the heat dissipation component comprising:

[0007] The two sets of motion blocks 1 and 2 are both located in the liquid storage cavity and are spaced apart in a cross shape. The two sets of motion blocks 2 remain in the liquid storage cavity at fixed positions, and the two sets of motion blocks 1 are driven by the rotating shaft.

[0008] Multiple groups of inner cavities are provided inside the shell, one end of each group is connected to the liquid storage cavity, and the other end of each group is connected to each other;

[0009] When the two sets of moving blocks are driven by the rotating shaft to reciprocate, the space between the moving blocks 1 and 2 is changed, so that the coolant circulates through the liquid storage cavity and the multiple sets of inner cavities.

[0010] Furthermore, the heat dissipation component also includes ring layer 1 and ring layer 2. A fixing part fixed to the rotating shaft is fixed on the outside of ring layer 2, which is used to drive ring layer 2 to rotate synchronously with the rotating shaft. Ring layer 1 is fixed to the outside of the shell by bolts and is sleeved on the outer ring of ring layer 2. Ring layer 1 and ring layer 2 cover the opening part of the liquid storage chamber. The outer ring of ring layer 2 also extends with a snap-fit ​​edge that is sealed with ring layer 1. The inner sides of moving block 1 and moving block 2 are in contact with the inner wall of the liquid storage chamber, and the outer sides are in contact with ring layer 1 and ring layer 2. The moving block 1 and ring layer 2 are fixed by bolts.

[0011] Furthermore, the inner cavity is in a bent and extended shape, so as to increase its extending path within the shell.

[0012] Furthermore, the channels at one end of the multiple groups of inner cavities connected to each other are connecting cavities, which are ring-shaped and opened inside the shell.

[0013] Furthermore, an external connection end communicating with the connection cavity is installed on the outer side of the shell, and the outer side of the external connection end is used to connect a hose to guide and replace the coolant in the liquid storage cavity.

[0014] Furthermore, the moving block 2 is fixed to the inner wall of the liquid storage chamber by magnetic attraction, and the outer curved surface of the moving block 2 is integrally extended with an arc-shaped edge 2 that fits with the liquid storage chamber, and the arc-shaped edge 2 blocks one end of the local inner cavity, and the outer side of the moving block 1 is integrally extended with an arc-shaped edge 1 that fits on the inner side of the arc-shaped edge 2, and the ends of the arc-shaped edge 1 and the arc-shaped edge 2 are respectively against the moving block 2 and the moving block 1.

[0015] Furthermore, the inner and outer arc surfaces of the moving block 1 and the moving block 2 are both in contact with the inner and outer arc surfaces of the liquid storage chamber, and the side edges of the moving block 1 and the moving block 2 are both straight lines, and their extension lines coincide with the axis of the rotating shaft.

[0016] Furthermore, the coolant in the liquid storage chamber is a water-based coolant or an oil-based coolant.

[0017] Furthermore, a stator core is installed inside the shell, a frame is installed on the stator core, a rotor core is installed on the rotating shaft, and a magnet is also provided on the outside of the rotor core.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. When the robot joint is running, the shaft rotates back and forth, and the second ring drives the moving block 1 to rotate back and forth, changing the position between the moving block 1 and the moving block 2 to achieve spatial changes. The coolant can move outward and inward from the external connection end to achieve the replacement of the coolant, complete the cooling effect, and keep the axial flux motor state unchanged.

[0020] 2. The range of joint motion at different positions of the robot is different, so the range of rotation of the shaft is also different. Setting the motion block 2 to magnetic attraction can enable the motion block 2 to be pushed by the motion block 1. As long as the robot joint is performing reciprocating motion, the coolant can be replaced.

[0021] 3. The coolant is distributed in the shell, and the connecting cavity connects the various inner cavities. The overheating energy generated at the local position of the axial flux motor is dispersed through the coolant to avoid excessive heat concentration and overheating at the local position.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0034] See also Figures 1-9 , the present invention provides a technical solution: the axial flux motor is widely used, adopts an axial magnetic field design, has a flat structure, and is compact, making it particularly suitable for space-constrained robot joints. Its torque density is generally higher than that of a traditional radial motor, and it can provide greater torque in the same volume, meeting the joint drive's demand for high dynamic response. However, due to its compact size, heat dissipation components are relatively difficult to install. Even if heat dissipation components are installed, the effect of the heat dissipation component 4 is limited. Based on this, an integrated axial flux motor is proposed, comprising a main body 1, the main body 1 comprising a shell 2 and a rotating shaft 3 extending from the interior thereof, the shell 2 having a liquid storage chamber 21 at one end facing the rotating shaft 3 for carrying coolant, a heat dissipation component 4 being mounted on the liquid storage chamber 21, and the heat dissipation component 4 comprising:

[0035] The two sets of motion blocks 1 43 and the two sets of motion blocks 2 44 are both located in the liquid storage chamber 21 and are spaced apart in a cross shape. The two sets of motion blocks 2 44 remain in the liquid storage chamber 21 and are driven by the rotating shaft 3.

[0036] Multiple groups of inner cavities 22 are provided inside the housing 2, one end of each of the groups is connected to the liquid storage chamber 21, and the other end of each of the groups is connected to each other;

[0037] When the two sets of moving blocks 1 43 are driven by the rotating shaft 3 to reciprocate, the space between the moving block 1 43 and the moving block 2 44 is changed, so that the coolant circulates through the liquid storage chamber 21 and the multiple sets of inner channels 22 .

[0038] Specifically, two groups of moving blocks 1 43 and two groups of moving blocks 2 44 are cross-arranged in the liquid storage chamber 21, wherein the two groups of moving blocks 1 43 are driven to rotate by the rotating shaft 3, so the gap between the moving blocks 1 43 and the moving blocks 2 44 will change. At the same time, since one end of the multiple groups of inner cavities 22 are connected to the liquid storage chamber 21 and the other ends are connected to each other, when the gap between the moving blocks 1 43 and the moving blocks 2 44 is changed, the coolant located therein can circulate from the liquid storage chamber 21 and the inner cavities 22, so that the heat generated by the axial flux motor can be relatively evenly transferred to the shell 2, so that the shell 2 can evenly conduct the heat. It should be noted that the material of the shell 2 can be metal or other materials. If it is made of other materials, the heat dissipation effect may be limited, so the reciprocating coolant can greatly transfer the temperature.

[0039] The heat dissipation component 4 also includes a ring layer 1 41 and a ring layer 2 42. A fixing part 422 fixed to the outside of the ring layer 2 42 is fixed with a rotating shaft 3, which is used to drive the ring layer 2 42 to rotate synchronously with the rotating shaft 3. The ring layer 1 41 is fixed to the outside of the shell 2 by bolts and is sleeved on the outer ring of the ring layer 2 42. The ring layer 1 41 and the ring layer 2 42 cover the opening part of the liquid storage chamber 21. The outer ring of the ring layer 2 42 also extends with a snap-fit ​​edge 421 that is sealed with the ring layer 1 41. The inner sides of the moving block 1 43 and the moving block 2 44 are in contact with the inner wall of the liquid storage chamber 21, and the outer sides are in contact with the ring layer 1 41 and the ring layer 2 42. The moving block 1 43 and the ring layer 2 42 are fixed by bolts.

[0040] Specifically, the moving block 1 43 and the moving block 2 44 are restricted in the liquid storage chamber 21 by the ring layer 1 41 and the ring layer 2 42, wherein the moving block 1 43 and the moving block 2 44 are located at the lower end of the ring layer 1 41 on half of the outer circle, and the other half is located at the lower end of the ring layer 2 42. At the same time, the ring layer 2 42 is fixed to the moving block 1 43, so that the moving block 1 43 and the moving block 2 44 are restricted by the ring layer 1 41, and the moving block 1 43 can rotate with the ring layer 2 42. Although the ring layer 2 42 can rotate, it remains sealed with the ring layer 1 41 and the inner edge of the liquid storage chamber 21.

[0041] The inner cavity 22 is in a bent extension shape, which is used to increase the extension path within the shell 2. The inner cavity 22 is bent so that the inner cavity 22 extends from the shell 2, making it more widely distributed and facilitating the removal of heat. At the same time, the original state and shape of the axial flux motor can be maintained unchanged. During the operation of the robot joint, no interference will occur and no installation problems will occur.

[0042] The channel connecting one end of the multiple sets of internal lumens 22 is a connecting cavity 23. The connecting cavity 23 is annular and is provided inside the housing 2. The annular connecting cavity 23 is used to connect the multiple sets of internal lumens 22, so that the internal lumens 22 are connected to each other. When the gap between the moving block 1 43 and the moving block 2 44 changes, liquid can enter the internal lumens 22. Regardless of which internal lumens 22 it enters, it can move out of the external connecting end 24. It should be noted that, regardless of the intersection angle between the moving block 1 43 and the moving block 2 44, the portion between them can ensure communication with the internal lumens 22, allowing the coolant to move out of the internal lumens 22 when squeezed.

[0043] An external connection end 24 communicating with the connection chamber 23 is installed on the outside of the shell 2 . The outside of the external connection end 24 is used to connect a hose to guide and replace the coolant in the liquid storage chamber 21 .

[0044] Specifically, the outer end of the external connection end 24 is connected to the external coolant. When the angles of the moving block 1 43 and the moving block 2 44 change back and forth, the coolant in the liquid storage chamber 21 can be squeezed out from the external connection end 24, and the coolant can also be adsorbed from the outside to achieve the replacement of the coolant, making it easier to cool the axial flux motor. It should be noted that the external coolant can be set in a position that does not affect the rotation of the robot joint and is connected through a hose, which greatly increases the heat dissipation effect and avoids affecting the operation of the robot.

[0045] The moving block 2 44 is fixed to the inner wall of the liquid storage chamber 21 by magnetic attraction. The outer arc surface of the moving block 2 44 is integrally extended with an arc side 2 441 that fits with the liquid storage chamber 21. The arc side 2 441 blocks one end of the local inner cavity 22. The outer side of the moving block 1 43 is integrally extended with an arc side 1 431 that fits on the inner side of the arc side 2 441. The ends of the arc side 1 431 and the arc side 2 441 are respectively against the moving block 2 44 and the moving block 1 43.

[0046] Specifically, the motion block 2 44 is magnetic, so the motion block 2 44 can be pushed to move when the thrust is too large, but it will not be affected when the motion block 1 43 and the motion block 2 44 squeeze the coolant under normal circumstances. It should be noted that the range of motion of the robot joint can be changed, so the angle of rotation of the shaft 3 also needs to be changed. The motion block 1 43 is pushed to move, and when it is against the motion block 2 44, the motion block 2 44 can move together to avoid affecting the movement of the robot joint. The robot joint will recover after a large-scale movement, but the motion block 2 44 will not recover, so the gap between the motion block 1 43 and the motion block 2 44 will also increase, ensuring that the heat dissipation component 4 can operate stably no matter how large the range of the robot joint operation is. In addition, it will not hinder the 360° rotation of the robot joint.

[0047] The function of arc-shaped side 1 431 and arc-shaped side 2 441 is to ensure that a cavity state is maintained between the two. Of course, when arc-shaped side 1 431 rotates, the range of the cavity between the two will increase. Since it is already in a cavity state, there is already gas inside. Therefore, increasing the range within a certain range will only reduce the internal air pressure and will not affect operation. It should be noted that when the axial flux motor is operating, temperature will inevitably be generated, and this temperature will increase the air pressure in the part of the cavity formed by arc-shaped side 1 431 and arc-shaped side 2 441. Therefore, it can offset the problem of the internal air pressure drop caused by the operation of arc-shaped side 1 431 to a certain extent. It should also be noted that the cavity between arc-shaped side 1 431 and arc-shaped side 2 441 refers to the cavity between moving block 1 43 and moving block 2 44, as well as the outer portion of the cavity with overlapping arc-shaped side 1 431 and arc-shaped side 2 441.

[0048] The inner and outer arc surfaces of the moving block 1 43 and the moving block 2 44 are both in contact with the inner and outer arc surfaces of the liquid storage chamber 21 . The sides of the moving block 1 43 and the moving block 2 44 are both straight lines, and their extension lines coincide with the axis of the rotating shaft 3 .

[0049] Specifically, the side extension lines of the moving block 1 43 and the moving block 2 44 coincide with the axis of the rotating shaft 3, so that when the moving block 1 43 rotates, it can fit with the moving block 2 44 and replace the coolant to the greatest extent.

[0050] The coolant in the liquid storage chamber 21 is a water-based coolant or an oil-based coolant.

[0051] A stator core 8 is installed inside the shell 2, a skeleton 7 is installed on the stator core 8, a rotor core 5 is installed on the rotating shaft 3, and a magnet 6 is also provided on the outside of the rotor core 5. The stator core 8, skeleton 7, rotor core 5 and magnet 6 are all necessary structures of the axial flux motor, which is the existing technology and will not be described here.

[0052] The working principle of the present invention: The main function of the axial flux motor at the robot joint is to drive the robot to operate, wherein the robot operation often has repetitive movements, so the axial flux motor is in a reciprocating motion process. Since the robot joint position is restricted and the axial flux motor continuously reciprocates, the robot joint is prone to overheating, based on this, an improvement is proposed.

[0053] Specifically, when the robot joint is running, the shaft 3 is rotated back and forth and the ring layer 2 42 is driven to reciprocate through the fixing member 422, thereby realizing the reciprocating rotation of the two sets of motion blocks 1 43. The liquid storage chamber 21 is filled with coolant, and the coolant is connected to the outside through the inner cavity 22, the connecting cavity 23 and the outer connecting end 24. The inner cavity 22 has multiple channels and is interconnected through the connecting cavity 23. Therefore, Figure 5 and Figure 6 As shown, through Figure 3The ring layer 2 42 in the middle drives the moving block 1 43 to rotate back and forth, so that the spacing between the two groups of moving blocks 1 43 and the two groups of moving blocks 2 44 distributed in a cross shape changes. At the same time, due to the closed effect formed by the arc-shaped edge 1 431 and the arc-shaped edge 2 441, the two areas formed by the moving block 1 43, the moving block 2 44, the arc-shaped edge 1 431 and the arc-shaped edge 2 441 remain in a cavity state. The two areas change with the movement size of the rotating shaft 3, and the size of the other two areas formed by the moving block 1 43 and the moving block 2 44 also changes, so that the internal coolant is drawn, causing the coolant to move outward and inward from the external connection end 24, realizing the replacement of the coolant, completing the cooling effect, and keeping the state of the axial flux motor unchanged.

[0054] Secondly, the range of joint motion of the robot is different at different positions, so the range of rotation of the rotating shaft 3 is also different. By setting the motion block 2 44 to be magnetic, the motion block 1 43 can be fitted with the motion block 2 44 after rotating at an angle less than 90°, and the motion block 2 44 can continue to be pushed to move, which will not affect the range of motion of the robot. Similarly, when the robot joint moves in the opposite direction, the arc side 1 431 and the arc side 2 441 respectively offset the motion block 2 44 and the motion block 1 43, so the motion block 2 44 can also be pushed to move. It should also be noted that the replacement of the coolant is a change in the space between the motion block 1 43 and the motion block 2 44. As long as the robot joint is performing reciprocating motion, the replacement of the coolant is achieved, and at the same time, it will not affect the circular motion of the robot joint. It should also be noted that the inner cavity 22 has multiple groups and is distributed along the circumference of the liquid storage cavity 21. Figure 8 As shown, regardless of the positions of the moving block 1 43 and the moving block 2 44 , the coolant can be moved to the inner cavity 22 .

[0055] Since the coolant is distributed in the shell 2, it can be quickly absorbed by the coolant when the axial flux motor generates heat. At the same time, the internal cavities 22 of each are connected through the connecting cavity 23. Even if the axial flux motor generates overheating at a local position, it can be dispersed by the coolant, avoiding excessive concentration of heat and causing local overheating, thereby affecting the operation of the robot.
