[0002] In many current industrial fields, such as new energy vehicles, precision motor manufacturing, etc., annular magnets play an indispensable role as key components. These applications require magnets to not only have a high-strength magnetic field and stable performance, but also be able to adapt to complex and changeable working conditions. However, for the currently integrally formed annular magnets, especially those made of neodymium iron boron (NdFeB), although they have excellent magnetic properties, when accidentally dropped, they are extremely likely to break and decompose, and if a part is damaged, the whole needs to be replaced. Summary of the Utility Model

[0003] In order to solve the problems in the above background art, the utility model provides a splicable annular magnet.

Each spliced magnetic block can be spliced along the annular flange to form an annular magnet, and a fixing mechanism is further provided between each spliced magnetic block and the annular support.

[0005] By adopting the above technical solution, the annular flange and the embedding groove are inserted into each other, so that the annular support can be used as an installation platform for each spliced magnetic block, which can enhance the overall structural rigidity, and the damaged spliced magnetic blocks can be replaced. And a fixing mechanism is provided between them to ensure the stability of splicing.

[0006] Further, the fixing mechanism includes a retractable clamping platform provided on the upper end surface or the lower end surface of the annular flange and a clamping groove provided on the inner top wall or the bottom wall of the embedding groove for cooperating with the retractable clamping platform to lock.

[0007] By adopting the above technical solution, the retractable clamping platform and the clamping groove in the embedding groove cooperate to form a stable mechanical locking structure, ensuring the precise positioning and fixing of the spliced magnetic blocks on the annular support.

[0008] Further, a pressing end integrally connected with the retractable clamping platform is provided on the main body part, a displacement groove adapted to the retractable clamping platform and the pressing end is provided on the annular support, and an elastic member is provided in the displacement groove.

[0009] By adopting the above technical solution, the pressing end and the retractable clamping platform can be pressed and displaced along the displacement groove, so that the spliced magnetic blocks can be disassembled, and the elastic member can reset the retractable clamping platform.

[0010] Furthermore, the elastic member is a wave spring, and there are two wave springs, which are respectively arranged at the bottom of the pressing end and the bottom of the telescopic clamping platform.

[0011] By adopting the above technical solution, the wave spring has good resilience characteristics, which can ensure that the pressing end and the telescopic platform can quickly reset after being pressed.

[0012] Furthermore, the annular support member is made of silicon steel.

[0013] By adopting the above technical solution, the high magnetic permeability can guide and concentrate magnetic lines of force, improve the magnetic field efficiency of the magnet, and has high mechanical strength and resistance to deformation.

[0014] In summary, the beneficial effects of the present utility model are as follows: by using the annular support member made of silicon steel as the core framework, the overall structural stability of the magnet is significantly enhanced, and an annular flange is provided on the peripheral side for a plurality of splicing magnets to be assembled along the annular support member to form an assembled annular magnet, so that when a single assembled magnet is damaged, it can be independently replaced without replacing the entire annular magnet, reducing the maintenance cost. And a telescopic clamping platform and a clamping groove are arranged between the annular support member and the assembled magnet for matching and locking, ensuring the precise connection of the assembled magnet, and at the same time, the fixation can be quickly cancelled through the pressing end.
