[0029] Specifically, the housing 100 is formed with an accommodating space 110, the kinetic flywheel 11 is arranged in the accommodating space 110, and the housing 100 is provided with a recovery groove 124; the protective part 200 is constructed on the inner circumferential wall of the housing 100 and is arranged outside the kinetic flywheel 11, and the protective part 200 is arranged opposite to the recovery groove 124; wherein the protective part 200 comprises a plurality of protective groups 210, and the plurality of protective groups 210 are arranged outside the kinetic flywheel 11 in a circumferential direction, and the debris generated during the use of the kinetic flywheel 11 acts on the plurality of protective groups 210 for multiple times of buffering and settling.

[0030] It should be noted that, during the use of the kinetic flywheel 11, energy is suitable to be transmitted into the kinetic flywheel 11 for storage, and during the use of the extreme working condition of the kinetic flywheel 11, debris is suitable to be generated, the debris is suitable to be thrown out by the kinetic flywheel 11 and to act on the inner circumferential wall of the housing 100, and the debris may collide and rebound with the housing, thereby possibly colliding with the rotor for a second time or even multiple times, so as to cause a large amount of instantaneous crushing of the high-speed rotor and an instantaneous structural crushing energy explosion. Therefore, how to buffer the debris to reduce the influence on the inner circumferential wall of the housing 100 is crucial, and meanwhile, during the long-time use, the accumulation of the debris will affect the use of the kinetic flywheel 11, and therefore, how to buffer and store the debris is very necessary. Meanwhile, the material used in the production process of the kinetic flywheel 11 is relatively valuable, and if the material is recycled, the cost can be significantly reduced, and how to recycle and reuse the material is needed to be solved.

[0031] The present application provides a protective assembly 10 for a kinetic flywheel 11, which is suitable to comprise a housing 100 and a protective part 200, the housing 100 is suitable to provide an accommodating space 110, so that the kinetic flywheel 11 can be arranged in the accommodating space 110 according to the design, and when the kinetic flywheel 11 is running and storing energy, the transmitted energy is suitable to be converted into kinetic energy for storage. The debris generated during the use of the kinetic flywheel 11 in the present application is suitable to act on the protective part 200 for buffering, so as to avoid the debris from directly acting on the housing 100 for impact, thereby improving the use reliability of the housing 100.

[0032] Specifically, the housing 100 is adapted to be constructed with a containing space 110, so that the kinetic energy flywheel 11 can be arranged in the containing space 110, and the containing space 110 is adapted to provide space for rotation of the kinetic energy flywheel 11, so that the kinetic energy flywheel 11 can rotate and store energy according to the design, and the protective part 200 is arranged on the inner circumferential wall of the housing 100, and since the protective part 200 is arranged on the outer circumferential side of the kinetic energy flywheel 11, the debris generated by the kinetic energy flywheel 11 during use can impact the protective part 200 after being thrown out by the kinetic energy flywheel 11, and the protective part 200 has a buffering and sinking effect, avoiding the debris of the kinetic energy flywheel 11 impacting the housing 100 after cracking under extreme working conditions, and improving safety.

[0033] Furthermore, the recycling groove is arranged at the bottom of the housing 100 opposite the protective group 210, so that the debris guided by the protective group 210 is guided to the recycling groove for containing and recycling, thereby facilitating subsequent recycling and reuse, and reducing use cost.

[0034] In some specific embodiments, the protective part 200 is adapted to include a plurality of protective groups 210, which are arranged on the outer circumferential side of the kinetic energy flywheel 11 in an axially spaced manner, so that the debris generated by the kinetic energy flywheel 11 after cracking can be buffered by the protective groups 210 when being thrown out in the circumferential direction, and since the protective groups 210 can buffer and sink the debris, the debris is prevented from impacting the housing 100, thereby improving safety and reliability.

[0035] According to the protective assembly 10 for the kinetic energy flywheel 11 of the embodiment of the present application, the protective part 200 is constructed in the housing 100, and since the protective part 200 is arranged on the outer side of the kinetic energy flywheel 11 in a circumferentially spaced manner, the debris generated by the kinetic energy flywheel 11 during use, or the debris generated by the kinetic energy flywheel 11 due to cracking, can be buffered and sunk by the protective part 200, so as to avoid the debris impacting the housing 100, thereby improving use safety and reliability. Furthermore, the protective part 200 is arranged opposite the recycling groove 124, so that the debris buffered and recycled by the protective part 200 can be guided and transmitted into the recycling groove 124, thereby facilitating recycling and reuse, and effectively reducing cost.

[0036] In some embodiments, each of the plurality of protective groups 210 comprises a first protective layer 211, a second protective layer 212, and a third protective layer 213, which are sequentially sleeved outside the flywheel 11 from inside to outside. That is, the plurality of protective groups 210 are arranged circumferentially on the outside of the flywheel 11, and the structure of the plurality of protective groups 210 is arranged in the same way, so that the assembly process of the protective assembly 10 is simpler and more efficient, and the production efficiency is improved. In some specific embodiments, the protective group 210 comprises a first protective layer 211, a second protective layer 212, and a third protective layer 213, and since the first protective layer 211, the second protective layer 212, and the third protective layer 213 are sequentially arranged on the outside of the flywheel 11, the debris fragments of the flywheel 11 can be sequentially buffered on the first protective layer 211, the second protective layer 212, and the third protective layer 213, and multiple buffering can reduce the impact effect, avoid the impact of debris fragments on the shell 100, and thus improve the reliability.

[0037] In some embodiments, the first protective layer 211 is a plastic energy-absorbing protective layer, the second protective layer 212 is a flexible energy-absorbing protective layer, and the third protective layer 213 is a magnetic buffering protective layer. That is, the first protective layer 211 is set as a plastic energy-absorbing protective layer, so that the first protective layer 211 can capture the initially impacted fragments to absorb the impact of the debris fragments and reduce the subsequent impact of the debris fragments after passing through the first protective layer 211. Similarly, the second protective layer 212 is set as a flexible energy-absorbing protective layer, which is suitable for being acted on by the debris fragments after passing through the first protective layer 211, and the second protective layer 212 is set as a flexible energy-absorbing protective layer to further absorb the kinetic energy of the debris fragments and constrain them. In addition, the third protective layer 213 is a magnetic buffering protective layer, so that the magnetic field generated by the third protective layer 213 can magnetically repel and guide the debris fragments, thereby absorbing the remaining kinetic energy as much as possible. At the same time, the magnetic field also guides and accommodates the debris fragments, avoiding the influence of the debris fragments on the shell 100, and the magnetic field can also deliver the debris fragments into the recycling groove 124 for accommodation and collection, facilitating recycling and reducing costs.

[0038] In some embodiments, a plurality of limiting grooves 120 are circumferentially and spaced apart on the peripheral wall of the shell 100, and the limiting grooves 120 are oppositely arranged with the protective part 200, and the protective part 200 is correspondingly arranged in the limiting groove 120. It can be understood that the limiting groove 120 provided on the inner peripheral wall of the shell 100 is suitable for providing a position for the assembly of the protective part 200, so that the protective part 200 can be arranged in the limiting groove 120 according to the design, so that the protective part 200 can buffer and settle the debris fragments of the flywheel 11 according to the design, thereby improving the safety.

[0039] In some embodiments, the limiting groove 120 comprises, from inside to outside, a first installation groove 121, a second installation groove 122 and a third installation groove 123, the first protective layer 211 is inserted into the first installation groove 121, the second protective layer 212 is inserted into the second installation groove 122, and the third protective layer 213 is arranged in the third installation groove 123. That is, the limiting groove 120 is adapted to be provided with the first installation groove 121, the second installation groove 122 and the third installation groove 123, the first installation groove 121 is adapted to provide a position for the first protective layer 211, so that the first protective layer 211 can be assembled in the first installation groove 121 according to the design, and the insertion installation mode can simplify the assembly process and improve the assembly efficiency. Similarly, the second installation groove 122 is adapted to provide a position for the assembly of the second protective layer 212, so that the second protective layer 212 can be assembled into the second installation groove 122 according to the design. Moreover, the third installation groove 123 can provide a space for the magnetic field generated by the third protective layer 213, so that the magnetic field can buffer and guide the settlement of the debris, thereby guiding the debris into the recycling groove, improving the safety of the protective assembly 10, facilitating the recycling of materials, and reducing the use cost.

[0040] In some embodiments, the third protective layer 213 comprises a plurality of vertically spaced magnetic bodies 214, which are fixedly arranged on the outer peripheral wall of the shell 100, and the magnetic field generated by the plurality of magnetic bodies 214 is in the third installation groove 123. It can be understood that the third protective layer 213 is adapted to comprise a plurality of magnetic bodies 214, which are arranged on the outer peripheral wall of the shell 100, so that the magnetic field formed by the plurality of magnetic bodies 214 can be formed in the third installation groove 123, so that the magnetic field can absorb and buffer the debris according to the design, reduce or even avoid the contact and impact of the debris with the shell 100, and have higher reliability. At the same time, the magnetic field generated by the magnetic body 214 can guide the debris to the recycling groove arranged in the corresponding protective part, so as to simplify the recycling process and reduce the use cost.

[0041] In some embodiments, in the vertical direction, the magnetic field density of the magnetic body 214 on the upper side is less than that of the magnetic body 214 on the lower side. In this way, by arranging the magnetic field density of the magnetic body 214 on the upper side to be less than that of the magnetic body 214 on the lower side, the magnetic field formed by the third protective layer 213 is a gradient magnetic field with upper comb and lower density, so that the gradient magnetic field can guide the debris to settle downward according to the design, avoid the recontact of the debris with the kinetic flywheel 11, and have higher safety. At the same time, the debris can be guided into the recycling groove 124 for collection, reducing the use influence, and facilitating the recycling and reuse of the kinetic flywheel debris, thereby reducing the use cost.

[0042] In some specific embodiments, the magnetic body 214 is a permanent magnet. In this way, the magnetic body 214 is set as a permanent magnet to enable the magnetic body 214 to provide a stable magnetic field to drive the settlement of the debris fragments, so as to avoid the influence of the debris fragments on the use of the kinetic energy flywheel 11, and improve the use reliability. At the same time, a stable magnetic field can also be generated to guide the debris fragments into the recycling groove 124 for recycling, thereby reducing the use cost.

[0043] In some embodiments, the vertical projection of the shell 100 is a regular polygon. In this way, the vertical projection of the shell 100 is set as a regular polygon, so that the number of edges of the regular polygon is the same as the number of the plurality of protection groups 210, so that the plurality of protection groups 210 can be arranged on the outer side of the kinetic energy flywheel 11 in a designed circumferential direction, to settle the debris fragments generated by the kinetic energy flywheel 11 during use, thereby improving the use reliability of the protection assembly 10.

[0044] The energy storage device according to the embodiments of the present application comprises the protection assembly 10 for the kinetic energy flywheel 11 as described above. In this way, since the protection assembly 10 as described above is provided in the energy storage device, the protection assembly 10 is arranged on the outer side of the kinetic energy flywheel 11 in a circumferential direction by being constructed in the shell 100. The debris generated by the kinetic energy flywheel 11 during use, or the debris generated by the cracking of the kinetic energy flywheel 11 can be buffered and settled by the protection assembly 200, so as to avoid the debris from impacting on the shell 100, thereby improving the safety and reliability of the energy storage device. Furthermore, the protection assembly 200 is arranged opposite to the recycling groove 124, so that the debris buffered and collected by the protection assembly 200 can be guided and delivered into the recycling groove 124, so as to be recycled and reused, thereby effectively reducing the cost.
