Technical Field
[0001] This utility model relates to the field of magnetic tiles, specifically a magnetic tile with a self-cooling guide groove. Background Technology
[0002] A magnetic tile is a permanent magnet with a specific shape, mainly used in motors to generate a constant magnetic field. It is one of the core components for converting electrical energy into mechanical energy. A DC motor is a rotating motor that can convert DC electrical energy into mechanical energy. Its internal structure mainly consists of two parts: the stator and the rotor. The stator of a traditional DC motor is made of coil windings. A magnetic field is generated by passing current through the coils. Due to the large volume of the coil windings, the overall size, weight, and efficiency of the DC motor are limited.
[0003] To address this problem, people use permanent magnets to replace coil windings to generate a magnetic field. Since permanent magnets can be made into various shapes as needed, they are generally made into tile-shaped structures and are called magnetic tiles. Magnetic tiles generate a lot of heat due to eddy current losses and hysteresis losses during use. If heat dissipation is not timely, the temperature will exceed its upper temperature limit, which will lead to demagnetization.
[0004] In the prior art, magnetic tiles are mostly made of brittle materials, which are prone to breakage or detachment due to impact or centrifugal force during high-speed rotation, vibration or assembly. Therefore, this utility model proposes a magnetic tile with a self-cooling guide groove to solve the above problems. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0025] Example 1: Please refer to Figures 1-9 This utility model provides a technical solution: a magnetic tile with a self-cooling guide groove, including a rotor 1. The outer surface of the rotor 1 is provided with several sets of magnetic tile bodies 2. Each set of magnetic tile bodies 2 has a guide groove 5 on its outer surface. The guide groove 5 on the surface of the magnetic tile increases the surface area of the magnetic tile compared to a smooth surface, thereby improving the contact efficiency with the cooling medium to a certain extent. The outer side of the magnetic tile body 2 is provided with a first arc-shaped protective shell 3 and a second arc-shaped protective shell 4. The first arc-shaped protective shell 3 and the second arc-shaped protective shell 4 can wrap and fix the magnetic tile, disperse stress, and prevent the magnetic tile from cracking to a certain extent. The upper sides of the left and right ends of the first arc-shaped protective shell 3 are provided with locking blocks 11, and the upper side walls of the left and right ends of the second arc-shaped protective shell 4 are provided with locking grooves 14. The surface of the first arc-shaped protective shell 3 is provided with a first ventilation groove 6, and the surface of the second arc-shaped protective shell 4 is provided with a second ventilation groove 7.
[0026] When using the first arc-shaped protective shell 3 and the second arc-shaped protective shell 4, the first arc-shaped protective shell 3 and the second arc-shaped protective shell 4 are respectively provided with the first ventilation groove 6 and the second ventilation groove 7. If the magnetic tile does not have ventilation grooves, the protective cover may block the heat dissipation channel of the guide groove 5, resulting in heat accumulation. The first ventilation groove 6 and the second ventilation groove 7 balance protection and heat dissipation to a certain extent.
[0027] Example 2: Based on Example 1, each set of magnetic tile body 2 has three sets of guide grooves 5 on its outer surface, and each set of magnetic tile body 2 has four sets of mounting holes 10 on its inner side. The four sets of mounting holes 10 are located at the four corners of the inner side of the magnetic tile body 2. The mounting holes 10 allow the adhesive to flow into the mounting holes 10 before curing during the installation of the magnetic tile, thereby enhancing the adhesion between the magnetic tile and the iron core. Two sets of limiting holes 9 are provided in the middle of the outer surface of the magnetic tile body 2. Two sets of limiting posts 20 are provided on the inner ring surface of the second arc-shaped protective shell 4. One end of the two sets of limiting posts 20 is fixedly connected to the inner ring surface of the second arc-shaped protective shell 4, and the two sets of limiting posts 20 are located in the middle of the inner ring surface of the second arc-shaped protective shell 4.
[0028] When installing the second arc-shaped protective shell 4, align the two sets of limiting posts 20 with the two sets of limiting holes 9 opened on the outer surface of the magnetic tile body 2, and insert them into the limiting holes 9. This can limit the position of the second arc-shaped protective shell 4 and prevent it from shaking up and down during use.
[0029] Example 3: Based on Example 2, a fixing groove 15 is provided at the bottom of the slot 14. An installation groove 16 is provided on one side of the fixing groove 15. One side of the fixing groove 15 is connected to the slot 14, and the other side is connected to the installation groove 16. A triangular locking block 17 is provided inside the installation groove 16, and a spring 19 is provided on one side of the triangular locking block 17. The spring 19 is located inside the installation groove 16, with one end fixedly connected to the side wall of the installation groove 16 and the other end fixedly connected to the side wall of the triangular locking block 17. An adjustment groove 8 is provided on the outer surface of the second arc-shaped protective shell 4. The adjustment groove 8 is located on one side of the triangular locking block 17 and is connected to the installation groove 16. 6. An adjustment block 18 is provided in the adjustment groove 8. One end of the adjustment block 18 is fixedly connected to one side of the triangular block 17. By adjusting the adjustment block 18, the adjustment block 18 is pulled to one side. At this time, the adjustment block 18 moves in the adjustment groove 8, which drives the triangular block 17 to move into the mounting groove 16. The spring 19 is compressed at this time. When the triangular block (17) is completely located in the mounting groove 16, the fixing block 12 can be taken out from the fixing groove 15. The block 11 and the fixing block 12 are pulled out from the slot 14. The fixing block 12 is fixedly installed at the bottom of the block 11. The fixing block 12 has a limit groove 13 on the side near the first arc-shaped protective shell 3.
[0030] When installing the first arc-shaped protective shell 3 and the second arc-shaped protective shell 4, align the locking block 11 and the fixing block 12 with the locking groove 14 and lock them into the locking groove 14. Move the first arc-shaped protective shell 3 downward. At this time, the fixing block 12 is locked into the fixing groove 15. The triangular locking block 17 is compressed under force and locked into the limiting groove 13. At this time, the installation of the first arc-shaped protective shell 3 and the second arc-shaped protective shell 4 can be completed, and the magnetic tile can be wrapped and fixed.
[0031] In actual use, the mounting hole 10 enhances the adhesion between the magnetic tile and the iron core, preventing the magnetic tile from loosening or falling off during high-speed rotation. The mounting hole 10 can also expel air from the bonding surface, reduce air bubbles in the adhesive layer, and improve heat conduction efficiency. By inserting the limiting post 20 into the limiting hole 9, the position of the second arc-shaped protective shell 4 can be limited. Align the locking block 11 and fixing block 12 on one side of the first arc-shaped protective shell 3 with the locking groove 14, and the triangular locking block 17 is locked into the limiting groove 13, thus completing the installation of the first arc-shaped protective shell 3 and the second arc-shaped protective shell 4.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
