Description

Technical Field

[0001] This utility model belongs to the field of magnetic tile technology, and in particular relates to a heat dissipation type magnetic tile structure. Background Technology

[0002] Magnet tiles are arc-shaped permanent magnets, mostly made of ferrite or neodymium iron boron pressed and sintered. They can fit tightly against the inner wall of the motor and are used to replace the excitation coil to form a constant air gap magnetic field. They are the core component of permanent magnet DC motors. The arc-shaped structure can optimize the magnetic field distribution, reduce the size of the motor and reduce energy consumption. They are widely used in micro motors such as fans, automobiles and power tools. They can also be assembled inside speakers to form a magnetic circuit. The stability of the magnetic field directly determines the operating efficiency of the equipment.

[0003] However, most magnetic heat dissipation structures are cast or welded to the bracket as a whole. When it is necessary to replace the heat sink with different specifications according to different motor models, the entire bracket assembly can only be replaced, which greatly increases the cost of disassembly and assembly, thus leading to poor parts compatibility. Utility Model Content

[0016] Please see Figure 1-5 As shown, this utility model is a heat dissipation type magnetic tile structure, including a frame 111 and a plurality of mounting slots 112 opened on the frame 111, and also includes: a replacement part 2, of which a plurality of replacement parts 2 are provided, and the plurality of replacement parts 2 are all disposed in the mounting slots 112; and a fixing part 3, which is disposed on the top of the frame 111. The replacement unit 2 includes a replacement component 21, which is disposed in the mounting groove 112; and a positioning component 22, which is disposed on the replacement component 21. The replacement component 21 includes a magnetic tile 211 slidably connected in the mounting groove 112. Two ball heads 212 are fixedly connected to the outer wall of the magnetic tile 211. Each ball head 212 is fitted with an elastic buckle 213. A heat sink 214 is fixedly connected to the side of the two elastic buckles 213 that is close to each other. A heat conduction plate 215 is fixedly connected to the side of the heat sink 214 that is close to the magnetic tile 211. The heat conduction plate 215 is in contact with the magnetic tile 211. The positioning component 22 includes two positioning rod groups 221 fixedly connected to the upper and lower sides of the heat sink 214. A plurality of positioning slots 222 are opened on the outer wall of the heat sink 214. The plurality of positioning rod groups 221 extend into the plurality of positioning slots 222. The outer walls of the plurality of positioning rod groups 221 are slidably connected to the plurality of positioning slots 222 respectively.

[0017] The fixing part 3 includes a fixing component 31, which is disposed on the top of the frame 111; and a limiting component 32, which is disposed on the fixing component 31. The fixing component 31 includes a plurality of fixing rods 311 fixedly connected to the top of the frame 111. The outer walls of the plurality of fixing rods 311 are slidably connected to fixing rings 312. A limiting groove 313 is formed on the top of the fixing ring 312. A limiting ring 314 is rotatably connected in the limiting groove 313. A fixing member is provided on the limiting ring 314. The fixing member includes a plurality of insert rods 315 fixedly connected to the limiting ring 314. The outer walls of the plurality of fixing rods 311 are... Each component has a slot 316, and several insert rods 315 extend into the slots 316. The outer walls of the insert rods 315 are slidably connected to the slots 316. The limiting component 32 includes a rectangular groove 321 on the top of the fixing ring 312. The outer wall of the limiting rotating ring 314 is fixedly connected to a fixing plate 322. The fixing plate 322 is provided with a limiting element. The fixing plate 322 is slidably connected to the rectangular groove 321. The fixing element includes a screw 323 threadedly connected to the top of the fixing plate 322. The bottom end of the screw 323 extends into the fixing ring 312, and the outer wall of the screw 323 is rotatably connected to the fixing ring 312.

[0018] One specific application of this embodiment is as follows: When replacing, the screws 323 on the fixing plate 322 can be removed with a screwdriver to release the limitation on the fixing plate 322. Then, the limiting ring 314 can be rotated to make the four insert rods 315 on it rotate synchronously. Under the guidance of the limiting groove 313, the four insert rods 315 are completely pulled out from the slots 316 on the outer wall of the four fixing rods 311, thereby releasing the limitation lock between the fixing ring 312 and the four fixing rods 311. Then, the fixing ring 312 can be removed from the top of the frame 111. At this time, the magnetic tile 211 and the heat sink 214 on the frame 111, which are slidably connected in several mounting slots 112 on the frame 111, lose their clamping constraint and can be easily pulled out and disassembled. After the magnetic tile 211 and the heat sink 214 are pulled out of the mounting slot 112, the heat sink 214 can be pulled outwards. This causes the two elastic clips 213 on the heat sink 214 to deform elastically under the pulling force, thereby disengaging from the two ball heads 212 on the outer wall of the magnetic tile 211. At the same time, the four positioning rod assemblies 221 on the upper and lower sides of the heat sink 214 will also slide out from the corresponding four positioning slots 222 on the outer wall of the magnetic tile 211. At this point, the heat sink 214 is completely separated from the magnetic tile 211. Then, a new heat sink 214 is taken and its two... The elastic buckle 213 is aligned with the two ball heads 212 on the magnetic tile 211 and pushed in, so that the elastic buckle 213 re-locks the ball heads 212. At the same time, it is ensured that the four positioning rod groups 221 are respectively inserted into the corresponding positioning slots 222, thus completing the assembly of the new heat sink 214 and the magnetic tile 211. Finally, the assembled magnetic tile 211 and the new heat sink 214 are reinserted into the mounting slot 112. Then, the fixing ring 312 is reinstalled in reverse order, and the limiting ring 314 is rotated to allow the four insertion rods 315 to be reinserted into the slots 316. The screws 323 are tightened to complete the entire replacement operation.
