[0036] Embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, but should not be understood as limiting the present disclosure.
[0037] like Figures 1 to 5 As shown, the rotor 100 of the axial flux motor of the embodiment of the present disclosure includes a rotor disk 1 and a magnetic steel 2. The rotor disk 1 includes a first bracket 11 and a second bracket 12. The second bracket 12 is arranged on one side of the first bracket 11 in the axial direction of the rotor 100 and is connected to the first bracket 11. The first bracket 11 is provided with a first clamping portion 1121, and the second bracket 12 is provided with a second clamping portion 1221. The magnetic steel 2 is clamped between the first clamping portion 1121 and the second clamping portion 1221 in the axial direction of the rotor 100.
[0038] In the axial flux motor of the embodiment of the present disclosure, the rotor disk 1 is configured to include a first bracket 11 and a second bracket 12 connected to each other, and a first clamping portion 1121 is provided on the first bracket 11, and a second clamping portion 1221 is provided on the second bracket 12, and the magnetic steel 2 is clamped between the first clamping portion 1121 and the second clamping portion 1221 in the axial direction of the rotor 100, thereby realizing axial limitation of the magnetic steel 2. When machining the rotor disk 1, it is only necessary to machine the first clamping portion 1121 on the first bracket 11 and the second clamping portion 1221 on the second bracket 12, thereby reducing the machining complexity of the rotor disk 1, thereby reducing the cost of the rotor 100 of the axial flux motor.
[0039] In the related art, bolts are usually used to connect the two internal components of the axial flux motor. Not only is the connection efficiency low, but there is also a risk of the bolts loosening when the rotor runs at high speed, and they may even fall into the air gap between the rotor and the stator, causing the axial flux motor to burn out.
[0040] In some embodiments, Figures 1 to 4 As shown, the second bracket 12 and the first bracket 11 are connected by rivets 4 .
[0041] For example, Figure 3 , Figures 6 to 8 As shown, the first bracket 11 is provided with a first connecting hole 1123, the second bracket 12 is provided with a second connecting hole 1212, the rivet 4 passes through the first connecting hole 1123 and the second connecting hole 1212, and the rivet 4 is squeezed along the axial direction of the rotor 100 to deform the two ends of the rivet 4, thereby realizing the connection between the first bracket 11 and the second bracket 12.
[0042] The first bracket 11 and the second bracket 12 are connected by the rivet 4, which can not only improve the connection efficiency between the first bracket 11 and the second bracket 12, but also avoid the risk of the bolts loosening and falling, thereby improving the reliability of the axial flux motor.
[0043] In some embodiments, Figure 3 , Figures 5 to 8 As shown, the first bracket 11 includes a first ring body 111 and a plurality of first clamping strips 112, the plurality of first clamping strips 112 are arranged at intervals along the circumference of the first ring body 111, and the first clamping portion 1121 is provided on the first clamping strip 112. The second bracket 12 includes a second ring body 121 and a plurality of second clamping strips 122, the plurality of second clamping strips 122 are arranged at intervals along the circumference of the second ring body 121, the second ring body 121 is connected to the first ring body 111, and the second clamping portion 1221 is provided on the second clamping strip 122.
[0044] For example, the number of the first clamping bars 112 and the number of the second clamping bars 122 are both eight, the eight first clamping bars 112 are evenly spaced along the circumference of the rotor 100 , and the eight second clamping bars 122 are evenly spaced along the circumference of the rotor 100 .
[0045] By configuring the first bracket 11 to include a first ring body 111 and a plurality of first clamping strips 112, configuring the second bracket 12 to include a second ring body 121 and a second clamping strip 122, and utilizing the first ring body 111 to connect with the second ring body 121, the connection between the first bracket 11 and the second bracket 12 is achieved, and utilizing the first clamping strip 112 and the second clamping strip 122 to clamp the magnetic steel 2, the structures of the first bracket 11 and the second bracket 12 are simplified, and the processing and manufacturing of the first bracket 11 and the second bracket 12 are facilitated, thereby further reducing the cost of the rotor 100 of the axial flux motor.
[0046] Alternatively, if Figure 6 As shown, the first clamping strip 112 is provided with a limiting portion 1122 , and the limiting portion 1122 abuts against the magnetic steel 2 along the circumferential direction of the rotor 100 .
[0047] By providing a limiting portion 1122 on the first clamping strip 112, the limiting portion 1122 is used to stop the magnetic steel 2 along the circumferential direction of the rotor 100, so as to limit the magnetic steel 2 in the circumferential direction of the rotor 100, facilitate the processing and manufacturing of the first bracket 11, and further reduce the cost of the rotor 100 of the axial flux motor.
[0048] Alternatively, if Figure 6 As shown, the first clamping strip 112 includes a first surface and a second surface, the first surface intersects with the second surface, the first surface forms a first clamping portion 1121, and the second surface forms a limiting portion 1122. Fig. 9 As shown, the magnetic steel 2 includes a first limiting surface 21 and a second limiting surface 22 . The first limiting surface 21 intersects with the second limiting surface 22 . The first limiting surface 21 stops at the first surface, and the second limiting surface 22 stops at the second surface.
[0049] For example, Figure 6As shown, the first surface is perpendicular to the second surface, as Fig. 9 As shown, the first limiting surface 21 is perpendicular to the second limiting surface 22 .
[0050] By forming the first clamping portion 1121 on the first surface of the first clamping strip 112 and the limiting portion 1122 on the second surface, the structure of the first clamping strip 112 is simplified, which facilitates the processing and manufacturing of the first bracket 11, thereby further reducing the cost of the rotor 100 of the axial flux motor.
[0051] like Figure 6 As shown, the first clamping strip 112 has two second surfaces, which are respectively arranged on opposite sides of the first clamping strip 112 in the circumferential direction of the rotor 100. In two adjacent first clamping strips 112, the second surface of each first clamping strip 112 facing the other first clamping strip 112 is used to cooperate with the same magnetic steel 2 to achieve the limiting of the magnetic steel 2 in the circumferential direction of the rotor 100.
[0052] Optionally, the first clamping bars 112 and the second clamping bars 122 are arranged alternately and spaced apart along the circumferential direction of the rotor 100 .
[0053] By arranging the first clamping strips 112 and the second clamping strips 122 alternately and spaced along the circumferential direction of the rotor 100 , the first clamping strips 112 and the second clamping strips 122 are respectively clamped at different positions of the magnetic steel 2 , thereby improving the clamping reliability of the magnetic steel 2 and thus improving the reliability of the rotor 100 .
[0054] Alternatively, if Figure 3 and Fig. 9 As shown, the magnetic steel 2 is provided with a limiting groove 23 , and the second clamping strip 122 is disposed in the limiting groove 23 .
[0055] By arranging the second clamping strip 122 in the limiting groove 23 of the magnetic steel 2, not only the second clamping strip 122 is utilized to clamp the magnetic steel 2, but also the second clamping strip 122 can be prevented from protruding out of the magnetic steel 2 along the axial direction of the rotor 100, thereby reducing the axial dimension of the rotor 100 and facilitating a lightweight design of the rotor 100.
[0056] Optionally, the magnetic steel 2 is bonded to the rotor disk 1 .
[0057] For example, the first limiting surface 21 and the first clamping portion 1121 , the second limiting surface 22 and the limiting portion 1122 , and the groove wall of the limiting groove 23 and the second clamping strip 122 are bonded by colloid.
[0058] The magnetic steel 2 is bonded to the rotor disk 1 , which can improve the connection reliability between the magnetic steel 2 and the rotor disk 1 , and further improve the reliability of the rotor 100 .
[0059] In some embodiments, Figure 3 , Figure 6 and Figure 8 As shown, the first bracket 11 is provided with a slot 1111 , the notch of the slot 1111 faces the radial outer side of the rotor 100 , and the second bracket 12 is provided with a clamping protrusion 1211 , and the clamping protrusion 1211 is arranged in the slot 1111 .
[0060] For example, Figure 3 and Figure 6 As shown, the first ring body 111 is provided with a slot 1111. Figure 8 As shown, the second ring body 121 is provided with a locking protrusion 1211 , and the locking protrusion 1211 is disposed in the locking groove 1111 .
[0061] By arranging the engaging protrusion 1211 in the engaging groove 1111 , the first bracket 11 and the second bracket 12 are limited in the axial direction of the rotor 100 , thereby improving the connection reliability of the first bracket 11 and the second bracket 12 , and further improving the reliability of the rotor 100 .
[0062] Alternatively, if Figure 3 and Figure 6 As shown, the size of the slot 1111 in the circumferential direction of the rotor 100 is larger than the size of the engaging protrusion 1211 in the circumferential direction of the rotor 100. The first bracket 11 is provided with a mounting slot 1112, which is communicated with the slot 1111 and allows the engaging protrusion 1211 to pass through in the radial direction of the rotor 100.
[0063] When the first bracket 11 and the second bracket 12 are assembled, the clamping protrusion 1211 is first passed through the notch of the installation groove 1112 along the radial direction of the rotor 100 and enters the clamping groove 1111, and then rotated along the circumferential direction of the rotor 100 by a certain angle (for example, 22.5°) so that the clamping protrusion 1211 is staggered with the installation groove 1112 to prevent the clamping protrusion 1211 from escaping from the installation groove 1112, thereby achieving the axial limitation of the first bracket 11 and the second bracket 12 in the rotor 100. Afterwards, the first bracket 11 is connected to the second bracket 12 to achieve a stable connection between the first bracket 11 and the second bracket 12.
[0064] The installation groove 1112 is provided to facilitate the insertion of the engaging protrusion 1211 into the engaging groove 1111 , which is beneficial to improving the assembly efficiency of the first bracket 11 and the second bracket 12 , and further reducing the cost of the rotor 100 of the axial flux motor.
[0065] Alternatively, if Figure 3 , Figure 6 and Figure 8As shown, the clamping groove 1111 is annular, and the number of the mounting grooves 1112 and the clamping protrusions 1211 are both multiple, and the multiple mounting grooves 1112 are arranged at intervals along the circumference of the rotor 100. The mounting grooves 1112 and the clamping protrusions 1211 correspond one to one, and the mounting grooves 1112 allow the corresponding clamping protrusions 1211 to pass through along the radial direction of the rotor 100.
[0066] For example, the number of the mounting grooves 1112 and the number of the clamping protrusions 1211 are both eight, the eight mounting grooves 1112 are evenly spaced along the circumference of the rotor 100 , and the eight clamping protrusions 1211 are evenly spaced along the circumference of the rotor 100 .
[0067] Specifically, when the first bracket 11 and the second bracket 12 are assembled, the engaging protrusion 1211 passes through the notch of the corresponding mounting groove 1112 along the radial direction of the rotor 100 and enters into the engaging groove 1111 .
[0068] By setting the slot 1111 to be annular and setting the number of the mounting slots 1112 and the snap-fit protrusions 1211 to be multiple, the axial limiting reliability of the first bracket 11 and the second bracket 12 on the rotor 100 can be improved, further improving the reliability of the rotor 100 of the axial flux motor.
[0069] In some embodiments, Figures 1 to 5 , Fig.10 As shown, the clamping ring 3 is also included. The clamping ring 3 is sleeved on the rotor disk 1 and connected to the rotor disk 1 , and the inner circumferential surface 31 of the clamping ring 3 abuts against the outer circumferential surface of the magnetic steel 2 .
[0070] The retaining ring 3 may be made of carbon fiber, which wraps around the outer peripheral surface of the magnetic steel 2 to achieve radial positioning of the magnetic steel 2 and prevent the magnetic steel 2 from detaching from the rotor disk 1 under the action of centrifugal force when the rotor 100 rotates.
[0071] The clamping ring 3 is provided to facilitate radial positioning of the magnetic steel 2 , thereby further reducing the cost of the rotor 100 of the axial flux motor.
[0072] The rotor 100 assembly method of the axial flux motor of the present disclosure embodiment:
[0073] The clamping protrusion 1211 of the second bracket 12 passes through the mounting groove 1112 of the first bracket 11 along the radial direction of the rotor 100, and enters the clamping groove 1111 through the mounting groove 1112;
[0074] The second bracket 12 is rotated along the circumferential direction of the rotor 100 so that the engaging protrusion 1211 is engaged in the engaging groove 1111. After the second connecting hole 1212 is aligned with the first connecting hole 1123, the second bracket 12 is stopped from rotating.
[0075] Insert the rivet 4 into the second connection hole 1212 and the first connection hole 1123 along the axial direction of the rotor 100, and squeeze the two sides of the rivet 4 along the axial direction of the rotor 100 so that the rivet 4 is in an I-shape as a whole, thereby connecting the second bracket 12 with the first bracket 11;
[0076] Apply glue to the surface of the magnetic steel 2 that contacts the rotor disk 1, and insert the magnetic steel 2 between the first clamping strip 112 and the second clamping strip 122 along the radial direction of the rotor 100;
[0077] The retaining ring is installed on the radial outer side of the magnetic steel 2 to complete the assembly of the rotor 100.
[0078] The rotor 100 of the axial flux motor of the embodiment of the present disclosure has the following advantages:
[0079] The rotor disk 1 has a simple structure and is easy to manufacture, which is beneficial to reducing the cost of the rotor 100 of the axial flux motor;
[0080] There is no need to use bolts to fasten the first bracket 11 and the second bracket 12 , and the rotor disk 1 and the retaining ring 3 , which not only improves the assembly efficiency of the rotor 100 , but also avoids the risk of the screws loosening and falling, thereby improving the reliability of the rotor 100 .

[0082] Since the cost of the rotor 100 of the axial flux motor according to the embodiment of the present disclosure is relatively low, the axial flux motor according to the embodiment of the present disclosure has the advantages of low cost and the like.
[0083] The vehicle of the embodiment of the present disclosure includes the axial flux motor described in any of the above embodiments, wherein the vehicle can be a pure electric vehicle or a hybrid electric vehicle.
