Embodiment

The schematic perspective view of motor coil module of Fig. 1 display present invention with fixing device.Fig. 2 shows that the present invention has The perspective exploded view of the motor coil module of fixing device.Coordinate and refer to Fig. 1 and Fig. 2, in the present embodiment, with fixation The motor coil module 10 of device includes：One coil device 20, a sensor 30 and a fixing device 40.The coil device 20 is wrapped A pedestal 21 and coil 22 are included, the pedestal 21 has an at least lateral wall 211, had between an at least lateral wall 211 and coil 22 There is a space 23.The sensor 30 contacts coil 22, to sense the state of coil 22.The fixing device 40 is arranged at the space 23, to fix the sensor 30.

The pedestal 21 separately includes a central portion 212 and multiple support arms（It is not shown）, in the present embodiment, the pedestal 21 Including four support arms, the central portion 212 and four support arms are in crosswise, and coil 22 is wound on four support arms.The seat Body 21 may include multiple lateral walls 211, in the form of sheets arc, be arranged at outside coil 22.In the present embodiment, the pedestal 21 may include Four lateral walls 211, the grade lateral wall 211 can be silicon steel sheet.In other embodiments, Fig. 3 is refer to, the lateral wall is except above-mentioned Silicon steel sheet outside, separately include the rounded ring-type of an exterior ring cap 518, be arranged at outside silicon steel sheet.

Space 23 between coil 22 and the lateral wall 211 in two adjacent support arms is a sector space, the present embodiment In, with four sector spaces.The fixing device 40 may be disposed at one of them sector space.The fixing device 40 is one fan-shaped Column, it is corresponding with the sector space, and with the corresponding shape with the space 23, therefore the fixed of the fan-shaped column is filled The sector space can generally be filled up by putting 40.

In the present embodiment, the fixing device 40 of the fan-shaped column have a first side 41, a second side 42 and Coil 22 on one arc-shaped side edges 43, the wherein second side 42 contact support arm, that is, support branch using the second side 42 Coil 22 in brace, makes the sensor 30 in the first side 41 positively contact the coil 22；Arc-shaped side edges 43 can connect Touch or do not contact the lateral wall 211.The first side 41 of the fixing device 40 has a housing region 44, to accommodate the sense Survey device 30.The housing region 44 is rectangle groove, coordinates the oblong-shaped of the sensor 30, may be disposed at the sensor 30 The housing region 44.Because the thickness of the sensor 30 is more than the thickness of the housing region 44, therefore the sensor 30 slightly protrudes from this First side 41, therefore the first side 41 is not in contact with the coil 22.When the fixing device 40 and the sensor 30 are arranged at the sky Between 23 when, the fixing device 40 can fix the sensor 30 by the coil 22, and positively contact the coil 22.The fixation is filled It can be rubber or silica gel material to put 40.

With reference to Fig. 4, it shows the schematic diagram of another embodiment of fixing device of the present invention.In other embodiments, this is consolidated It can be soft changable shape material to determine device 60, such as foam, and the sensor 30 is coated to deform.Therefore, the fixing device 60 fixing devices 40 for being not required to the embodiment such as Fig. 2 have housing region.The sensor 30 compressing is arranged at the fixing device 60 side, makes the side depressed deformation of the fixing device 60, and the sensor 30 is coated to accommodate.Similarly, this is fixed When device 60 and the sensor 30 are arranged at the space, the sensor 30 can be also fixed by the coil, and positively contact should Coil.

Referring again to Fig. 1 and Fig. 2, in the present embodiment, the sensor 30 switchs for an overheat protector, to sense coil 22 Temperature, and when the temperature of coil 22 is more than a predetermined value, make the open circuit of coil 22, to avoid the constant temperature of coil 22 from rising, protect Protective ring 22.In other embodiments, the sensor can be an overcurrent protection circuit or short switch, can sense the electricity of coil Size is flowed, when coil current is too big or short-circuit, coil open circuit can be made, to avoid coil burnout, coil is protected.Therefore, this hair The sensor 30 of bright embodiment can sense the various states of coil 22, for example：Temperature, curtage etc., to protect coil.

The pedestal 21 separately includes an at least outer part 213, and an at least outer part 213 is arranged at coil 22 and the lateral wall Between 211.In the present embodiment, the pedestal 21 includes four outer parts 213, wherein an outer part 213 includes an extension projection 214, extend along the circumferential direction of the lateral wall 211, there is a buckle space between the extension projection 214 and the lateral wall 211 215.The circumferential lateral edge 43 of the fixing device 40 separately has a locating convex block 45, and it is empty that the locating convex block 45 is just placed in the buckle Gap 215, further to position the fixing device 40 in the space 23.And the buckle space 215 times is arc portion 217 in one, it is wide Degree is more than the outer part 213, makes the locating convex block 45 by the limitation of the interior arc portion 217, is arranged in the interior arc portion 217, and It is arranged at the buckle space 215.

In the present embodiment, a upper limb of the extension projection 214 has one first lead angle structure 216, the locating convex block 45 A lower edge have one second lead angle structure 451.When installing the fixing device 40 in the space 23, the extension projection is utilized The cooperation of 214 the first lead angle structure 216 and the second lead angle structure 451 of the locating convex block 45, can make the locating convex block 45 are from top to bottom successfully placed in the buckle space 215.

Fig. 3 is refer again to, it shows the schematic diagram of another embodiment of coil device of the present invention.Coil compared to Fig. 2 Device 20, the dextrorotation of coil device 50 of the invention is turn 90 degrees, to clearly illustrate the buckle space 515.

The only principle and its effect of above-described embodiment only to illustrate the invention, and it is not used to the limitation present invention.Therefore, practise in The personage of this technology, which modifies and changed to above-described embodiment, does not take off spirit of the invention still.The interest field of the present invention should be as Listed by foregoing claim.
