Description

Technical Field

[0001] The utility model belongs to the technical field of magnetic tiles, and particularly relates to combined magnetic tiles. Background Art

[0002] Magnetic tiles are tile-shaped magnets mainly used in permanent magnet motors. They can be divided into various types according to different materials and shapes, and have high coercivity and good temperature stability. Magnetic tiles can be divided into integral magnetic tiles and combined magnetic tiles. Integral magnetic tiles are usually integrally formed, and a single large magnetic tile is used on the rotor or stator of the motor. Its main advantages are simple structure and uniform magnetic field, which are suitable for motors with standard sizes. Combined magnetic tiles are composed of multiple small magnetic blocks, and through specific structural design and splicing methods, the size and shape can be conveniently adjusted.

[0003] One installation method of the existing combined magnetic tiles is to insert a fixing clip between every two magnetic tiles, and then use a tool to expand the baffles on both sides of the fixing clip to firmly hold the magnetic tiles for positioning and fixing. However, this method will cause wear to the magnetic tiles and is not convenient for later replacement. Therefore, a combined magnetic tile that is convenient for installation and later disassembly is required. Content of the Utility Model

[0004] In view of the problem in the prior art that one installation method of the existing combined magnetic tiles is to insert a fixing clip between every two magnetic tiles, and then use a tool to expand the baffles on both sides of the fixing clip to firmly hold the magnetic tiles for positioning and fixing. However, this method will cause wear to the magnetic tiles and is not convenient for later replacement, the following technical solutions are proposed:

[0005] A main body assembly, the main body assembly includes magnetic tiles;

[0006] There are four magnetic tiles in total, which are symmetrically distributed in a ring shape;

[0007] A positioning assembly, the positioning assembly includes a fixing block, a circular through hole, a groove, a square through hole, an adjusting rod, a movable block and a spring;

[0008] The fixing block is attached to the side of the magnetic tile, the groove is opened at the lower end of the fixing block, the circular through hole is opened at the upper end of the fixing block and communicates with the groove, the square through hole is opened on both sides of the groove, the adjusting rod is screwed in the circular through hole, the movable block is movably connected in the groove, the spring is sleeved on the movable block, and one end of the spring is fixed at one end of the movable block and the other end is fixed at the side of the square through hole.

[0009] The magnetic tiles can generate a constant magnetic potential source in the motor. Four magnetic tiles form a whole and are evenly attached to the inner wall of the stator housing. The fixing blocks play a supporting and connecting role. The circular through-holes play a connecting and adjusting role. By cooperating with the up and down movement of the adjusting rod, the position change can be realized. The grooves provide a storage function. The square through-holes play a limiting role and at the same time provide a moving channel for the movable block. The movable block is used to firmly press against the magnetic tiles. The spring has a reset function. During specific use, the adjusting rod can rotate up and down along the circular through-hole, driving the movable block to move along the square through-hole to achieve the firm fastening of the magnetic tiles.

[0010] As a preference of the above technical solution, there are four groups of the positioning components, which are respectively connected and inserted between every two magnetic tiles.

[0011] Four magnetic tiles form a whole, making the magnetic field more uniform. Each two are fixed by the positioning components. The four groups of positioning components make the four magnetic tiles firmly attached to the inner wall of the stator housing.

[0012] As a preference of the above technical solution, there are two movable blocks, and the movable blocks are trapezoidal, with the inclined surface ends located directly below the adjusting rod.

[0013] Two movable blocks are provided to firmly press against the magnetic tiles on both sides respectively, making the connection more stable.

[0014] As a preference of the above technical solution, the movable blocks are movably connected to the lower end of the adjusting rod and are also movably connected within the square through-holes.

[0015] When the adjusting rod rotates and moves downward, it can drive the movable blocks to move within the grooves and move outwards from the square through-holes to fit against the magnetic tiles. And the movable blocks are trapezoidal, and the adjusting rod and the movable blocks can achieve positioning at different positions.

[0016] As a preference of the above technical solution, the main body component further includes a stator housing, and the stator housing wraps outside the magnetic tiles and fits against the magnetic tiles.

[0017] The stator housing plays a protective role. The magnetic tiles are installed on the inner wall of the stator housing and can generate an interaction force with the rotating rotor part.

[0018] As a preference of the above technical solution, an adjusting component is further included;

[0019] The adjusting component includes a fixing plate, a connecting shaft, a connecting plate and an anti-slip rubber block;

[0020] There are two fixing plates, which are fixed on both sides of the end of the movable block far away from the adjusting rod. The connecting shaft is fixed between the fixing plates. The connecting plate is sleeved on the connecting shaft, and the anti-slip rubber block is fixed on the side of the connecting plate.

[0021] The fixing plate plays a connecting role. The connecting shaft facilitates the rotation of the connecting plate. The connecting plate plays a connecting role. The anti-slip rubber block can prevent the magnetic tile from being worn. The anti-slip rubber block can fit the magnetic tile. At this time, the connecting plate on the other side of the anti-slip rubber block can rotate around the connecting shaft on the fixing plate, so that the anti-slip rubber block can completely fit the magnetic tile and increase the contact area.

[0022] The beneficial effects of the present utility model are as follows:

[0023] (1) In the present utility model, through the provided positioning assembly, four magnetic tiles are attached to the inner wall of the stator housing. The fixing block is inserted between every two magnetic tiles. By rotating the adjusting rod with an internal hexagonal tool, the adjusting rod moves downward along the circular through-hole, driving the two movable blocks in the groove to move outward along the square through-hole to firmly hold the magnetic tiles. After installing four groups of positioning assemblies in sequence, if disassembly is required, rotate the adjusting rod in the reverse direction so that the adjusting rod disengages from the movable block. The movable block resets under the action of the spring and disengages from the magnetic tile, and then the fixing block and the magnetic tile can be taken out in sequence. This setting facilitates the installation and disassembly of the magnetic tiles, has simple operation and strong applicability;

[0024] (2) In the present utility model, through the provided adjusting assembly, when the movable block moves outward along the square through-hole, it drives the fixing plate and the connecting shaft to move outward, and further drives the anti-slip rubber block on the connecting plate to move outward. The anti-slip rubber block fits the side of the magnetic tile and drives the connecting plate to rotate around the connecting shaft. This setting can make the anti-slip rubber block completely fit the side wall of the magnetic tile, increase the contact area and improve the connection stability. Description of the Drawings

[0031] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0032] Please refer to Figures 1-4 as shown. This embodiment is a combined magnetic tile, including:

[0033] A main body component, which includes a magnetic tile 11;

[0034] There are four magnetic tiles 11 in total, which are symmetrically distributed in a ring shape;

[0035] A positioning component, which includes a fixing block 20, a circular through hole 21, a groove 22, a square through hole 23, an adjusting rod 24, a movable block 25 and a spring 26;

[0036] The fixing block 20 is attached to the side of the magnetic tile 11. The groove 22 is opened at the lower end of the fixing block 20. The circular through hole 21 is opened at the upper end of the fixing block 20 and communicates with the groove 22. The square through hole 23 is opened on both sides of the groove 22. The adjusting rod 24 is screwed in the circular through hole 21. The movable block 25 is movably connected in the groove 22. The spring 26 is sleeved on the movable block 25, and one end of the spring 26 is fixed to one end of the movable block 25, and the other end is fixed to the side of the square through hole 23;

[0037] There are four groups of positioning components, which are respectively connected and inserted between every two magnetic tiles 11;

[0038] There are two movable blocks 25 in total, and the movable block 25 is trapezoidal, and the inclined surface end is located directly below the adjusting rod 24;

[0039] The movable block 25 is movably connected to the lower end of the adjusting rod 24 and is also movably connected in the square through hole 23;

[0040] The main body component further includes a stator housing 10, and the stator housing 10 wraps around the outside of the magnetic tile 11 and is attached to the magnetic tile 11.

[0041] Working principle:

[0042] The four magnetic tiles 11 are attached to the inner wall of the stator housing 10. The fixing block 20 is inserted between every two magnetic tiles 11. By turning the adjusting rod 24 with an inner hexagon tool, the adjusting rod 24 moves downward along the circular through hole 21, driving the two movable blocks 25 in the groove 22 to move outward along the square through hole 23 to firmly hold the magnetic tile 11. Just install the four groups of positioning components in sequence;

[0043] If disassembly is required, turn the adjusting rod 24 in the reverse direction, so that the adjusting rod 24 moves upward along the circular through hole 21. The lower end of the adjusting rod 24 disengages from the movable block 25. The movable block 25 resets under the action of the spring 26, and the movable block 25 disengages from the magnetic tile 11, and then the fixing block 20 and the magnetic tile 11 can be taken out in sequence.

[0044] This step facilitates the installation and disassembly of the magnetic tile 11, with simple operation and strong applicability.

[0045] Please refer to Figure 5 , and the embodiment further includes, on the basis of the above embodiments:

[0046] An adjusting assembly, which includes a fixing plate 30, a connecting shaft 31, a connecting plate 32 and an anti-slip rubber block 34;

[0047] There are two fixing plates 30, which are fixed on both sides of the end of the movable block 25 away from the adjusting rod 24. The connecting shaft 31 is fixed between the fixing plates 30. The connecting plate 32 is sleeved on the connecting shaft 31, and the anti-slip rubber block 34 is fixed on the side of the connecting plate 32.

[0048] Working principle:

[0049] When the movable block 25 moves outwards along the square through hole 23, it drives the fixing plate 30 and the connecting shaft 31 to move outwards, and then drives the anti-slip rubber block 34 on the connecting plate 32 to move outwards. As the anti-slip rubber block 34 gradually fits against the side of the magnetic tile 11, when the anti-slip rubber block 34 completely fits against the magnetic tile 11, the anti-slip rubber block 34 drives the connecting plate 32 to rotate around the connecting shaft 31 by a certain angle.

[0050] This step can make the anti-slip rubber block 34 completely fit against the side wall of the magnetic tile 11, increase the contact area, and improve the connection stability.

[0051] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
