Description

Technical Field

[0001] This invention relates to the field of energy storage, specifically to an energy storage flywheel rotor. Background Technology

[0002] Flywheel energy storage achieves the storage and release of electrical energy by increasing and decreasing the rotational speed of a composite material flywheel. When there is excess electrical energy, the rotational speed of the composite material flywheel is increased by an electric motor, thereby storing the electrical energy in the composite material flywheel as kinetic energy. When there is insufficient electrical energy, the rotational speed of the composite material flywheel is reduced to drive a generator to work, converting the kinetic energy stored in the composite material flywheel into electrical energy.

[0003] In related technologies, punching holes at the edge of the composite flywheel to reduce weight would disrupt the continuity of the fibers. Therefore, the problem of dynamic balance and weight reduction of fiber composite flywheels has always been an unsolvable problem. The common approach is to add weight, but the secondary curing of the weighted adhesive is unreliable. The adhesive strength of the resin alone is very low, and curing is required. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, embodiments of the present invention propose an energy storage flywheel rotor with a simple structure that can achieve dynamic balance.

[0006] According to an embodiment of the present invention, an energy storage flywheel rotor includes: a hub, wherein the outer peripheral surface of the hub is provided with a plurality of mounting grooves extending axially therefrom, at least one end of each mounting groove passing through the hub along the axial direction of the hub, and the plurality of mounting grooves being spaced apart circumferentially along the hub; and a composite material ring, the composite material ring including a first composite material ring and a second composite material ring, both the first composite material ring and the second composite material ring being sleeved on the hub and spaced apart axially along the hub, both the first composite material ring and the second composite material ring including a first portion and a second portion arranged sequentially along the radial direction of the composite material ring, the first portion being disposed within and connected to the second portion, the first portion including a plurality of connecting portions and a plurality of mounting... The hub comprises a plurality of connecting portions and a plurality of mounting portions arranged alternately along the circumference of the hub, with each end of a connecting portion connected to two adjacent mounting portions. The connecting portions extend along the circumference of the hub and are connected to the second part. The plurality of mounting portions are correspondingly inserted into the mounting groove. A plurality of adjusting members are correspondingly inserted into the mounting groove. The adjusting members are located between the outer circumferential surface of the mounting portion and the inner circumferential surface of the mounting groove. The outer circumferential surface of the adjusting members abuts against the inner circumferential surface of the mounting groove and the outer circumferential surface of the mounting portion. The adjusting members drive the composite material ring to move radially along the composite material ring via the mounting portion, so that the center of mass of the composite material ring coincides with the rotation center of the hub.

[0007] The energy storage flywheel rotor of this invention is provided with a mounting groove, a mounting part and an adjustment component, and the center of mass and the center of rotation of the composite material ring are adjusted to coincide. Compared with related technologies, the energy storage flywheel rotor 1 achieves dynamic balance without damaging the structure of the composite material ring, maintaining the integrity of the composite material ring and making it safer and more reliable.

[0008] In some embodiments, each mounting portion includes a mounting segment, a first arc-shaped segment, and a second arc-shaped segment. The outer peripheral surface of the mounting segment is in contact with the inner peripheral surface of the mounting groove. The first arc-shaped segment and the second arc-shaped segment are symmetrically arranged at intervals. The two ends of the first arc-shaped segment are respectively connected to the mounting segment and the adjacent connecting portion. The two ends of the second arc-shaped segment are respectively connected to the mounting segment and the adjacent connecting portion. Both the first arc-shaped segment and the second arc-shaped segment have a driving force that drives the mounting segment and the connecting portion away from each other.

[0009] In some embodiments, in a projection plane orthogonal to the axial direction of the hub, the mounting section includes a first section, a second section, and a third section. The first section and the third section are arranged parallel to each other at intervals, and one end of the first section and one end of the third section are respectively connected to the second section, so that the first section, the second section, and the third section form an outward-facing frame shape. The second section abuts against the outer peripheral surface of the adjusting member, and the first section and the third section abut against the inner peripheral surface of the mounting groove. The first arc-shaped section is connected to the other end of the first section, and the second arc-shaped section is connected to the other end of the third section. The first arc-shaped section is concave towards the direction adjacent to the second arc-shaped section, and the second arc-shaped section is concave towards the direction adjacent to the first arc-shaped section.

[0010] In some embodiments, the mounting groove includes a first mounting groove and a second mounting groove, and there are multiple first mounting grooves and multiple second mounting grooves. The multiple first mounting grooves and multiple second mounting grooves are spaced apart along the axial direction of the hub, and are also spaced apart along the circumferential direction of the hub. The first mounting groove extends from one end of the hub along the axial direction of the hub, and the second mounting groove extends from the other end of the hub along the axial direction of the hub. A first composite material ring is fitted onto the multiple first mounting grooves, and a second composite material ring is fitted onto the multiple second mounting grooves. The adjusting components include multiple first adjusting components and multiple second adjusting components. The multiple first adjusting components are correspondingly inserted into multiple first mounting slots. The first adjusting components are located between the outer peripheral surface of the mounting portion of the first composite material ring and the inner peripheral surface of the first mounting slot, so that the center of mass of the first composite material ring coincides with the rotation center of the wheel hub. The multiple second adjusting components are correspondingly inserted into multiple second mounting slots. The second adjusting components are located between the outer peripheral surface of the mounting portion of the second composite material ring and the inner peripheral surface of the second mounting slot, so that the center of mass of the second composite material ring coincides with the rotation center of the wheel hub.

[0011] In some embodiments, at least a portion of the first mounting groove is located outside the second mounting groove in a projection plane orthogonal to the axial direction of the hub.

[0012] In some embodiments, the adjusting member includes a drive rod and an adjusting plate, the adjusting plate extending axially along the hub and passing through the mounting portion and the mounting groove, and the adjusting plate abutting against the mounting portion, so that the adjusting plate drives the composite ring to move in the radial direction of the composite ring through the mounting portion to adjust the center of mass of the composite ring to coincide with the rotation center of the hub, and the drive rod passing through the mounting groove and located on the side of the adjusting plate opposite to the mounting portion.

[0013] In some embodiments, the side of the mounting groove facing the adjustment plate is a first mating surface, and the side of the adjustment plate facing the mounting groove is a second mating surface. The first mating surface is a first arcuate surface recessed away from the adjustment plate, and the second mating surface is a second arcuate surface recessed away from the mounting groove. The drive rod passes between the first arcuate surface and the second arcuate surface so that the drive rod drives the adjustment plate to move in the radial direction of the composite material ring.

[0014] In some embodiments, the drive rod includes a first sub-rod and a second sub-rod connected in a vertical direction. The diameter of the first sub-rod is larger than the diameter of the second sub-rod. The outer circumferential surface of the first sub-rod is provided with a guide thread. The mounting groove is provided with a threaded hole extending axially along the hub. The first sub-rod passes through the threaded hole by threaded engagement, and the second sub-rod abuts against the first arc surface of the adjustment plate.

[0015] In some embodiments, the outer peripheral surface of the second sub-rod is provided with a support thread, and the second arc surface is a threaded guide surface that mates with the support thread, so that when the first sub-rod passes through the threaded hole, the support thread of the second sub-rod is threadedly engaged with the threaded guide surface. The drive rod also includes a clamping part, which is provided at the free end of the second sub-rod, so that when the first sub-rod passes through the threaded hole, the clamping part clamps the adjusting plate.

[0016] In some embodiments, there are multiple types of drive rods, each of which has the same diameter for its first sub-rod and a different diameter for its second sub-rod. Attached Figure Description

Detailed Implementation

[0029] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] The energy storage flywheel rotor 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0031] like Figure 1-11 As shown, the energy storage flywheel rotor 100 according to an embodiment of the present invention includes a hub 1, a composite material ring 2, and a plurality of adjusting components 3.

[0032] The outer circumferential surface of hub 1 is provided with multiple axially extending (e.g.) Figure 1 As shown, mounting grooves 11 extend in the vertical direction, with at least one end of the mounting groove 11 penetrating the hub 1 along its axial direction. Multiple mounting grooves 11 are spaced apart circumferentially around the hub 1. Specifically, as... Figure 7 and Figure 8As shown, the outer circumferential surface of the hub 1 is provided with mounting grooves 11 that extend in the vertical direction and are equally spaced along the circumference of the hub 1. The mounting grooves 11 extend downward from the upper end face of the hub 1 or extend upward from the lower end face of the hub 1.

[0033] The composite material ring 2 includes a first composite material ring 23 and a second composite material ring 24. Both the first composite material ring 23 and the second composite material ring 24 are sleeved on the hub 1 and are spaced apart along the axial direction of the hub 1. Both the first composite material ring 23 and the second composite material ring 24 include a first part 21 and a second part 22 arranged sequentially along the radial direction of the composite material ring 2. The first part 21 is located inside the second part 22 and is connected to the second part 22. The first part 21 includes multiple connecting parts 211 and multiple mounting parts 212. The multiple connecting parts 211 and the multiple mounting parts 212 are arranged alternately along the circumference of the hub 1, and the two ends of the connecting parts 211 are respectively connected to two adjacent connecting parts 211. The connecting parts 211 extend along the circumference of the hub 1 and are connected to the second part 22. The multiple mounting parts 212 are correspondingly inserted into the mounting groove 11.

[0034] Specifically, such as Figures 2-5 As shown, the composite material ring 2 can be composed of n composite material rings with an interference fit. The composite material ring 2 includes a first composite material ring 23 and a second composite material ring 24, both of which are sleeved on the outer circumferential surface of the hub 1. The first composite material ring 23 and the second composite material ring 24 each include a first part 21 and a second part 22. The first part 21 is sleeved inside the second part 22 and fits with the second part 22 as a whole. Multiple connecting parts 211 and multiple mounting parts 212 are alternately arranged in a ring. The number of mounting parts 212 is equal to the number of mounting grooves 11. Each mounting groove 11 has a mounting part 212 inserted into it. The connecting part 211 is an arc-shaped part that extends circumferentially and is located between two adjacent mounting parts 212. The inner circumferential surface of the arc-shaped part and the outer circumferential surface of the hub 1 are spaced apart in the inward and outward directions. The two ends of the connecting part 211 are respectively connected to two adjacent mounting parts 212.

[0035] Multiple adjusting members 3 are correspondingly inserted into the mounting groove 11. The adjusting members 3 are located between the outer peripheral surface of the mounting part 212 and the inner peripheral surface of the mounting groove 11. The outer peripheral surface of the adjusting member 3 abuts against both the inner peripheral surface of the mounting groove 11 and the outer peripheral surface of the mounting part 212. The adjusting members 3 drive the composite material ring 2 to move radially in the composite material ring 2 via the mounting part 212, so that the center of mass of the composite material ring 2 coincides with the rotation center of the hub 1. Specifically, as shown... Figure 1-3As shown, the number of adjusting members 3 is equal to the number of mounting slots 11, and each mounting slot 11 is provided with an adjusting member 3. The adjusting member 3 is inserted into the mounting slot 11 and located on the side of the mounting part 212 away from the second part 22. The adjusting member 3 can drive the mounting part 212 to move in the inward and outward directions, and the adjusting member 3 and the mounting part 212 can move in the inward and outward directions to adjust the center of mass of the first composite material ring 23 and the center of mass of the second composite material ring 24 to coincide with the rotation center of the hub 1. The arrangement of the first composite material ring 23 and the second composite material ring 24 can make the torque generated by the first composite material ring 23 and the second composite material ring 24 equal in magnitude and opposite in direction when the energy storage flywheel rotor 100 rotates at high speed, thereby making the energy storage flywheel rotor 100 achieve dynamic balance.

[0036] The energy storage flywheel rotor 100 of this embodiment of the invention is provided with a mounting groove 11, a mounting part 212, and an adjusting member 3. The mounting part 212 can be installed in the mounting groove 11. The adjusting member 3 can not only adjust the center of mass and the center of rotation of the composite material ring 2 to coincide, but also make the energy storage flywheel rotor 100 achieve dynamic balance without damaging the structure of the composite material ring 2. Compared with related technologies, it maintains the integrity of the composite material ring 2 and is safer and more reliable. In addition, the adjusting member 3 can also generate an outward thrust on the composite material ring 2 by the mounting part 212, so that the composite material ring 2 is interference-fitted with the hub 1 through the cooperation of multiple mounting parts 212, multiple adjusting members 3 and multiple mounting grooves 11, providing a mounting foundation for the composite material ring. In addition, when the energy storage flywheel rotor 100 rotates at high speed, the thrust of the adjusting member 3 can also separate the composite material ring 2 during high-speed rotation, thereby improving the energy storage density of the energy storage flywheel rotor 100. In addition, due to the arrangement of the first arc segment 2122 and the second arc segment 2123, when the composite material ring 2 is installed on the hub 1, the first arc segment 2122 and the second arc segment 2123 can undergo elastic deformation. When the energy storage flywheel rotor 100 rotates at high speed, it can ensure that the second part 22 is always subjected to outward thrust, prevent the second part 22 from becoming loose, and ensure the energy storage efficiency of the energy storage flywheel rotor 100.

[0037] In some embodiments, each mounting portion 212 includes a mounting segment 2121, a first arcuate segment 2122, and a second arcuate segment 2123. The outer peripheral surface of the mounting segment 2121 is in contact with the inner peripheral surface of the mounting groove 11. The first arcuate segment 2122 and the second arcuate segment 2123 are symmetrically arranged at intervals. The two ends of the first arcuate segment 2122 are respectively connected to the mounting segment 2121 and the adjacent connecting portion 211. The two ends of the second arcuate segment 2123 are respectively connected to the mounting segment 2121 and the adjacent connecting portion 211. Both the first arcuate segment 2122 and the second arcuate segment 2123 have a driving force that drives the mounting segment 2121 and the connecting portion 211 away from each other. Specifically, as shown in the figure... Figure 3 and Figure 6 As shown, the mounting section 2121 passes through the mounting groove 11. The first arc-shaped section 2122 and the second arc-shaped section 2123 are symmetrically arranged at intervals along the front-back direction. The left ends of the first arc-shaped section 2122 and the second arc-shaped section 2123 are both connected to the mounting section 2121. The right end of the first arc-shaped section 2122 is connected to the adjacent connecting portion 211 of the first arc-shaped section 2122, and the right end of the second arc-shaped section 2123 is connected to the adjacent connecting portion 211 of the second arc-shaped section 2123. At least a portion of the first arc-shaped section 2122 and the second arc-shaped section 2123 are located within the mounting groove 11. The driving member is located at the left end of the mounting portion 212. Thus, the mounting portion 212 is driven in the left-right direction (e.g., ...) by the driving member. Figure 3 or Figure 6 (As shown in the inward and outward directions) the mounting part 212 moves upward, driving the first arc segment 2122 and the second arc segment 2123 to move. The first arc segment 2122 and the second arc segment 2123 drive the second part 22 to move in the left and right directions, thereby adjusting the center of mass of the composite material ring 2 to coincide with the rotation center of the hub 1. In addition, the first arc segment 2122 and the second arc segment 2123 have a driving force to drive the mounting part 2121 and the connecting part 211 away from each other. Thus, the composite material ring 2 can be separated during high-speed rotation, thereby improving the energy storage density of the energy storage flywheel rotor 100.

[0038] In some embodiments, within a projection plane orthogonal to the axial direction of the hub 1, the mounting segment 2121 includes a first segment 21211, a second segment 21212, and a third segment 21213. The first segment 21211 and the third segment 21213 are arranged parallel to each other at intervals, and one end of the first segment 21211 and one end of the third segment 21213 are respectively connected to the second segment 21212, so that the first segment 21211, the second segment 21212, and the third segment 21213 form an outward-facing opening. The frame is shaped such that the second segment 21212 abuts against the outer peripheral surface of the adjusting member 3, the first segment 21211 and the third segment 21213 abut against the inner peripheral surface of the mounting groove 11, the first arc segment 2122 is connected to the other end of the first segment 21211, the second arc segment 2123 is connected to the other end of the third segment 21213, the first arc segment 2122 is recessed toward the adjacent second arc segment 2123, and the second arc segment 2123 is recessed toward the adjacent first arc segment 2122.

[0039] Specifically, such as Figure 3 and Figure 6As shown, the mounting section 2121 can be a mounting frame and includes a first section 21211, a second section 21212, and a third section 21213 connected in sequence. The first section 21211 and the third section 21213 extend in the left-right direction, and the second section 21212 extends in the front-back direction. The left end of the first section 21211 and the left end of the third section 21213 are connected to the front and back ends of the second section 21212. The first section 21211 and the third section 21213 abut against the front and back sides of the inner circumferential surface of the mounting groove 11, respectively, so that the inner circumferential surface of the mounting section 2121 and the outer circumferential surface of the mounting groove 11 are in contact. When the energy storage flywheel rotor 100 rotates at high speed, it can prevent the mounting section 2121 from shaking in the mounting groove 11 and prevent the composite material ring 2 from sliding relative to the hub 1 in its circumferential direction, thus ensuring the energy storage efficiency of the energy storage flywheel. The adjusting member 3 is inserted between the second section 21212 and the left side of the inner circumferential surface of the mounting groove 11, so that the adjusting member 3 pushes the second section 21212 to push the composite material ring 2 to move in the radial direction of the composite material ring 2.

[0040] Furthermore, the first arc segment 2122 has its center located behind the first arc segment 2122, and its left side is connected to the right side of the first segment 21211. The second arc segment 2123 has its center located in front of the second arc segment 2123, and its left side is connected to the right side of the second segment 21212. The arc, length, and central angle of the first arc segment 2122 and the second arc segment 2123 are all equal. As a result, when the energy storage flywheel rotor 100 rotates at high speed, the deformation of the first arc segment 2122 and the second arc segment 2123 is the same, thus ensuring that the deformation of the composite material ring 2 is equal everywhere when the energy storage flywheel rotor 100 rotates at high speed. This ensures that when the energy storage flywheel rotor 100 rotates, the center of mass of the composite material ring 2 always coincides with the rotation center of the hub 1.

[0041] In some embodiments, the adjusting member 3 includes a drive rod 31 and an adjusting plate 32. The adjusting plate 32 extends axially along the hub 1 and passes through the mounting portion 212 and the mounting groove 11, with the adjusting plate 32 and the mounting portion 212 abutting each other. This allows the adjusting plate 32 to drive the composite material ring 2 to move radially in the composite material ring 2 via the mounting portion 212, thereby aligning the center of mass of the composite material ring 2 with the rotation center of the hub 1. The drive rod 31 passes through the mounting groove 11 and is located on the side of the adjusting plate 32 opposite to the mounting portion 212. Specifically, as shown... Figures 2-4As shown, both the drive rod 31 and the adjustment plate 32 extend in the vertical direction, and both the drive rod 31 and the adjustment plate 32 can be inserted into the mounting groove 11. The adjustment plate 32 is located between the drive member and the mounting part 212. Thus, by replacing the drive rod 31 with one of different diameters, the adjustment plate 32 can be driven to move in the inward and outward directions to adjust the position of the center of mass of the composite material ring 2. The thrust on the composite material ring 2 in the inward and outward directions can also be adjusted by the drive rod 31 and the adjustment plate 32 to prevent the composite material ring 2 from loosening when rotating at high speed.

[0042] In some embodiments, the side of the mounting groove 11 facing the adjusting plate 32 is a first mating surface 113, and the side of the adjusting plate 32 facing the mounting groove 11 is a second mating surface 321. The first mating surface 113 is a first arcuate surface recessed away from the adjusting plate 32, and the second mating surface 321 is a second arcuate surface recessed away from the mounting groove 11. The driving rod 31 passes between the first and second arcuate surfaces so that the driving rod 31 drives the adjusting plate 32 to move in the radial direction of the composite material ring 2. Specifically, as shown... Figure 9 and Figure 11 As shown, the left side of the mounting groove 11 is the first mating surface 113 and is a first arc surface, and the right side of the adjusting plate 32 is the second mating surface 321 and is a second arc surface. The center of the first arc surface is located inside the mounting groove 11 and is located to the right of the first arc surface, and the center of the second arc surface is located to the left of the adjusting plate 32. The drive rod 31 is a cylindrical rod. When the drive rod 31 passes through the mounting groove 11, the outer circumferential surface of the drive rod 31 can mate with the first arc surface and the second arc surface to make the outer circumferential surface of the drive rod 31 contact the first arc surface and the second arc surface, thereby improving the stability of the drive rod 31 and the adjusting plate 32 in the mounting groove 11.

[0043] In some embodiments, the drive rod 31 includes a first sub-rod 33 and a second sub-rod 34 connected in the vertical direction. The diameter of the first sub-rod 33 is larger than the diameter of the second sub-rod 34. The outer peripheral surface of the first sub-rod 33 is provided with a guide thread (not shown in the figure). The mounting groove 11 is provided with a threaded hole 114 extending axially along the hub 1. The first sub-rod 33 passes through the threaded hole 114 through a threaded engagement, and the second sub-rod 34 abuts against the first arc surface of the adjusting plate 32. Specifically, as shown... Figure 9 and Figure 10As shown, the first sub-rod 33 is mounted on the second sub-rod 34. The bottom of the mounting groove 11 is provided with a threaded hole 114 extending in the vertical direction. The first sub-rod 33 is provided with a guide thread extending in the vertical direction. The guide thread of the first sub-rod 33 and the threaded hole 114 are threadedly engaged, so that the first sub-rod 33 is fixed in the mounting groove 11. The second sub-rod 34 abuts against the second mating surface 321 of the adjusting plate 32 to provide tension to the composite material ring 2 in the inner and outer directions, so that the composite material ring 2 is fixed on the hub 1. The diameter of the second sub-rod 34 on the drive rod 31 can also be changed according to actual needs to adjust the energy storage flywheel rotor 100 to achieve dynamic balance.

[0044] In some embodiments, the outer peripheral surface of the second sub-rod 34 is provided with a support thread (not shown in the figure), and the second arc surface is a threaded guide surface that mates with the support thread, so that when the first sub-rod 33 passes through the threaded hole 114, the support thread of the second sub-rod 34 is threadedly engaged with the threaded guide surface. Specifically, as shown in the figure... Figure 10 As shown, the outer circumferential surface of the second sub-rod 34 is provided with a support thread extending in the vertical direction, and the second arc surface is provided with a threaded guide surface that mates with the support thread. When the drive rod 31 is installed in the mounting groove 11, the outer circumferential surface of the second sub-rod 34 is spaced apart from the inner circumferential surface of the mounting groove 11, and the inner circumferential surface of the second sub-rod 34 mates with the threaded guide surface. Thus, through the threaded engagement, the adjustment plate 32 is installed in the mounting groove 11. When the energy storage flywheel rotor 100 rotates at high speed, it can prevent the adjustment plate 32 from slipping out of the mounting groove 11 in the vertical direction, thus ensuring the stability of the installation of the adjustment plate 32.

[0045] In some embodiments, the drive rod 31 further includes a clamping portion 35 disposed at the free end of the second sub-rod 34, so that when the first sub-rod 33 passes through the threaded hole 114, the clamping portion 35 clamps the adjusting plate 32. Specifically, as shown in the figure... Figure 3 and Figure 10 As shown, the clamping part 35 is located at the upper end of the second sub-rod 34. When the drive rod 31 passes through the mounting hole, the clamping part 35 can clamp the upper end of the adjusting plate 32, thereby further positioning the adjusting plate 32 in the vertical direction and preventing the adjusting plate 32 from slipping out of the mounting groove 11.

[0046] In some embodiments, there are multiple types of drive rods 31. The diameter of the first sub-rod of each drive rod 31 is the same, while the diameter of the second sub-rod 34 of each drive rod 31 is different. Specifically, the drive rods 31 can be configured in multiple ways according to actual conditions. The diameter, length, and thread of the first sub-rod 33 of each drive rod 31 are the same, while the length and thread of the diameter of the second sub-rod 34 of each drive rod 31 are the same, but the diameter of the second sub-rod 34 of each drive rod 31 is different. Thus, the center of mass of the composite material ring 2 can be adjusted according to the length of the different diameters of the second sub-rods 34.

[0047] In some embodiments, the mounting groove 11 includes a first mounting groove 111 and a second mounting groove 112, with multiple first mounting grooves 111 and multiple second mounting grooves 112. The multiple first mounting grooves 111 and multiple second mounting grooves 112 are spaced apart along the axial direction of the hub 1, and are also spaced apart circumferentially along the hub 1. The first mounting groove 111 extends axially from one end of the hub 1, and the second mounting groove 112 extends axially from the other end of the hub 1. A first composite material ring 23 is fitted onto the multiple first mounting grooves 111, and a second composite material ring 24 is fitted onto the multiple second mounting grooves 112. Specifically, as shown... Figure 2 As shown, the mounting groove 11 includes a first mounting groove 111 and a second mounting groove 112, and there are multiple first mounting grooves 111 and multiple second mounting grooves 112. Multiple first mounting grooves 111 and multiple second mounting grooves 112 are spaced apart in the vertical direction on the outer peripheral surface of the hub 1. The first mounting groove 111 extends downward from the upper end of the hub 1, and the second mounting groove 112 extends upward from the lower end of the hub 1. Thus, the first composite material ring 23 is disposed at the upper end of the hub 1 through multiple first mounting grooves 111, and the second composite material ring 24 is disposed at the lower end of the hub 1 through multiple second mounting grooves 112. Thus, the arrangement of the energy storage flywheel rotor 100 is more reasonable.

[0048] In some embodiments, the plurality of adjusting members 3 include a plurality of first adjusting members and a plurality of second adjusting members. The plurality of first adjusting members are correspondingly inserted into a plurality of first mounting slots, with the first adjusting members located between the outer peripheral surface of the mounting portion of the first composite material ring 23 and the inner peripheral surface of the first mounting slot 111, so that the center of mass of the first composite material ring 23 coincides with the rotation center of the hub 1. The plurality of second adjusting members are correspondingly inserted into a plurality of second mounting slots 112, with the second adjusting members located between the outer peripheral surface of the mounting portion of the second composite material ring 24 and the inner peripheral surface of the second mounting slot 112, so that the center of mass of the second composite material ring 24 coincides with the rotation center of the hub 1. Thus, the center of mass of the first composite material ring 23 and the center of mass of the second composite material ring 24 are respectively adjusted to coincide with the rotation center of the hub 1 using the first adjusting members and the second adjusting members.

[0049] In some embodiments, in a projection plane orthogonal to the axial direction of the hub 1, at least a portion of the first mounting groove 111 is located outside the second mounting groove 112. Specifically, as Figure 7 and Figure 8As shown, multiple first mounting slots 111 and multiple second mounting slots 112 are staggered in the vertical direction. This allows the threaded holes 114 in the first mounting slots 111 and the threaded holes 114 in the second mounting slots 112 to be spaced apart in the circumferential direction of the hub 1. If the first mounting slots 111 and the second mounting slots 112 are spaced apart relative to each other in the vertical direction, the threaded holes 114 in the first mounting slots 111 and the threaded holes 114 in the second mounting slots 112 will also be spaced apart in the vertical direction. This will cause interference between the threaded holes 114 in the first mounting slots 111 and the threaded holes 114 in the second mounting slots 112 during processing. This ensures the length of the threaded holes 114 to guarantee the installation stability of the drive rod 31, thereby making the hub 1 more reasonably positioned.
