This design facilitates the disassembly and assembly of the motor and the fan main shaft. The motor cone sleeve is connected to the fan main shaft, and a second keyway device is provided in the inner hole to drive the fan main shaft to rotate.

The bolts are prone to thread slippage during rotation, thereby reducing work efficiency.

[0005] A brushless motor flange that is easy to assemble and disassemble is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the present utility model is to provide a brushless motor flange that is easy to assemble and disassemble, so as to solve the problem raised in the above background technology that a tapered surface is provided through the inner hole of the motor taper sleeve, the tapered surface cooperates with the tapered surface of the fan main shaft and the diameter of the inner hole is consistent with the diameter of the fan main shaft, which is convenient for the disassembly and assembly of the motor and the fan main shaft, but the motor disassembly process is relatively cumbersome and requires rotating the corresponding bolts for disassembly, and the bolts are prone to thread slippage during rotation, thereby reducing work efficiency.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a brushless motor flange that is easy to assemble and disassemble, comprising a limiting mechanism and a flange mounted on one side of the limiting mechanism;

[0008] A protective mechanism is provided on the outer side of the limiting mechanism, and one side of the protective mechanism is fixedly connected to the outer side of the brushless motor body;

[0009] Also includes:

[0010] The limiting mechanism includes a brushless motor body, one end of which is fitted and connected to a flange;

[0011] Among them, the interior of the flange is fixedly connected with a plurality of connecting rods, the number of the connecting rods is ten, and the connecting rods are evenly distributed inside the flange;

[0012] A groove is provided inside the connecting rod, and a push rod is slidably connected inside the groove.

[0013] Preferably, a first spring is sleeved on the outer side of the push rod, and one end of the first spring is in close contact with the groove.

[0014] Preferably, limiting grooves are symmetrically provided on both sides of one end of the push rod, and steel balls are provided inside the two limiting grooves.

[0015] Preferably, one side of the steel ball is fitted and connected to the push rod, and the other side of the steel ball is fitted and connected to a limiting block, and the outer side of the limiting block is threadedly connected to the brushless motor body.

[0016] Preferably, the protection mechanism includes a heat sink, and one side of the heat sink is fixedly connected to the brushless motor body.

[0017] Preferably, a plurality of cylinders are fixedly connected to the other side of the heat sink, the number of the cylinders is three groups, and the cylinders are evenly distributed on the outside of the heat sink, and a sleeve is provided on the outside of the top end of the cylinder.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: the brushless motor flange is easy to disassemble and assemble, and the flange on the brushless motor body can be quickly disassembled without using any tools by setting a limiting mechanism, thereby improving work efficiency. The protection mechanism can not only improve the heat dissipation efficiency of the brushless motor body, but also protect the outer side of the brushless motor body. The specific contents are as follows:

[0020] 1. By setting a limit mechanism, the flange on the brushless motor body can be quickly disassembled without using any tools, thereby improving work efficiency. By pressing the push rod inward to compress the first spring, the limit of the push rod on the steel ball is released. Pulling the connecting rod outward can make the steel ball fall into the groove along the limit groove, thereby releasing the limit of the steel ball limit block. The connecting rod can be pulled out from the limit block, and the flange can be quickly disassembled;

[0021] 2. By setting up a protective mechanism, not only the heat dissipation efficiency of the brushless motor body can be improved, but also the outside of the brushless motor body can be protected. When the outside of the brushless motor body is hit, the deformation of the protective cover can absorb part of the impact force. At the same time, the protective cover drives the sleeve to move inward, and uses the compression of the second spring to absorb part of the impact force. The second spring drives the sleeve to reset so that the cylinder contacts the damping particles, which can absorb part of the elastic force, thereby having a buffering and protective effect on the brushless motor body.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-6The present invention provides a technical solution: a brushless motor flange that is easy to assemble and disassemble, comprising a limiting mechanism 1 and a flange 102 installed on one side of the limiting mechanism 1; a protective mechanism 2 is provided on the outside of the limiting mechanism 1, and one side of the protective mechanism 2 is fixedly connected to the outside of the brushless motor body 101; the limiting mechanism 1 comprises a brushless motor body 101, one end of the brushless motor body 101 is fitted and connected to the flange 102, and a plurality of connecting rods 103 are fixedly connected to the inside of the flange 102, and the number of the connecting rods 103 is ten, and the connecting rods 103 are evenly distributed inside the flange 102. By providing ten connecting rods 103, the stability of the fixing of the flange 102 can be improved;

[0031] A groove 104 is formed inside the connecting rod 103, and a push rod 105 is slidably connected to the inside of the groove 104. A first spring 106 is sleeved on the outside of the push rod 105, and one end of the first spring 106 is in close contact with the groove 104. By providing the first spring 106, the push rod 105 can always limit the steel ball 108 when there is no external force.

[0032] Limiting grooves 107 are symmetrically provided on both sides of one end of the push rod 105. Steel balls 108 are provided inside the two limiting grooves 107. One side of the steel ball 108 is fitted and connected to the push rod 105, and the other side of the steel ball 108 is fitted and connected to a limiting block 109. The outer side of the limiting block 109 is threadedly connected to the brushless motor body 101. The flange 102 can be quickly fixed to the brushless motor body 101 by utilizing the cooperation between the steel balls 108 and the limiting blocks 109.

[0033] The protective mechanism 2 includes a heat sink 201. One side of the heat sink 201 is fixedly connected to the brushless motor body 101. The other side of the heat sink 201 is fixedly connected to a plurality of cylinders 202. The cylinders 202 are arranged in three groups and are evenly distributed on the outside of the heat sink 201. A sleeve 203 is provided on the outside of the top of the cylinder 202. Each group of cylinders 202 contains three cylinders 202, for a total of nine cylinders 202, which are evenly distributed on the outside of the heat sink 201.

[0034] The top end of the sleeve 203 is fixedly connected to a second spring 204, one end of the second spring 204 is fitted and connected to the cylinder 202, the bottom end of the sleeve 203 is fixedly connected to damping particles 205, the inside of the damping particles 205 is interlaced and connected with the cylinder 202, and the top end of the outer side of the sleeve 203 is fixedly connected to a protective cover 206. The compression of the second spring 204 is used to absorb part of the impact force. The second spring 204 drives the sleeve 203 to reset so that the cylinder 202 contacts the damping particles 205, which can absorb part of the rebound force.

[0035] Working principle: Before using this brushless motor flange that is easy to disassemble and assemble, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 6 As shown, the brushless motor body 101 is first installed in a designated position. When the outer side of the brushless motor body 101 is impacted, the deformation of the protective cover 206 can absorb part of the impact force. At the same time, the protective cover 206 drives the sleeve 203 to move inward, and the compression of the second spring 204 absorbs part of the impact force. The second spring 204 drives the sleeve 203 to return to its original position so that the cylinder 202 contacts the damping particles 205, which can absorb part of the elastic force, thereby providing a buffering and protective effect for the brushless motor body 101.

[0036] Secondly, when it is necessary to quickly remove the flange 102 on the brushless motor body 101, by pressing the push rod 105 inward to compress the first spring 106, the limit of the push rod 105 on the steel ball 108 is released, and the connecting rod 103 is pulled outward to make the steel ball 108 fall into the groove 104 along the limit groove 107, thereby releasing the limit of the limit block 109 of the steel ball 108, and the connecting rod 103 can be pulled out from the limit block 109, so that the flange 102 can be removed.

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
