Embodiment 1

The utility model embodiment provides a kind of motor.

Fig. 1 is the diagrammatic cross-section of an embodiment of the motor of the utility model embodiment 1；Fig. 2 is that this is practical new One schematic diagram of shell and bracket of the motor of type embodiment 1, shows a kind of positional relationship of groove portion Yu the first bonding plane；Figure 3 be one schematic diagram of shell and bracket of the motor of the utility model embodiment 1, the feelings before showing bracket and shell bonding Condition.

As shown in Figure 1 to Figure 3, motor 10 has motor body 11, shell 12 and bracket 13；Wherein, shell 12 covers At least part of motor body 11, at least side of shell 12 in the axial direction are formed with opening portion 120, and Fig. 1 shows shell Side S1 in 12 axial direction；Bracket 13 covers opening portion 120.

In the present embodiment, as shown in Figure 1 to Figure 3, shell 12 includes side 122 and stage portion 123, wherein side 122 are formed as tubular, and the inner circumferential of stage portion 123 from side 122 is prominent towards radially inner side；Bracket 13 includes 132 He of top cover portion Protruding portion 133, wherein top cover portion 132 extends along perpendicular to axial plane, and protruding portion 133 is from top cover portion 132 to close to motor The direction of main body 11 is prominent, and the side 122 of shell 12 has opposed forward surface with bracket 13 in the axial direction and/or radially OP, wherein the forward surface of the side 122 opposed with bracket 13 is known as OP1, and the forward surface of the bracket 13 opposed with side 122 claims For OP2, it is formed with the first bonding plane ST1 on the forward surface OP1 of side 122, it is viscous that second is formed on the forward surface OP2 of bracket 13 Junction ST2, side 122 and bracket 13 are mutually bonded and are fixed by the first bonding plane ST1 and the second bonding plane ST2.

In the present embodiment, as shown in Fig. 2, being provided with groove portion 14 circumferentially on the forward surface OP1 of side 122, Groove portion 14 and the first bonding plane ST1 are radially and/or axially adjacent.

Thus structure, by the way that groove portion is arranged near the bonding plane for having binder to cover, the binder overflowed from bonding plane It can be accommodated by the groove portion, to prevent binder from spilling into the interior outside of motor.

In the present embodiment, as shown in figure 3, when bracket 13 and shell 12 to be adhesively fixed, first in forward surface OP1 Binder is smeared on the first bonding plane ST1 formed and on the second bonding plane ST2 that forward surface OP2 is formed, then will be applied again The bonding plane for having smeared binder contacts with each other and compresses, to bond bracket 13 and shell 12 securely.

In the present embodiment, Fig. 3 shows in the axial direction and radially opposed forward surface OP and is formed with bonding plane, But the present embodiment is without being limited thereto, only in the axial direction or radially can also be formed with bonding plane in opposed forward surface OP.

In the present embodiment, as shown in Figures 2 and 3, plane where groove portion 14 may be provided at and axially vertical side 122 Forward surface OP1 (that is, axial face OP1-1 of forward surface OP1) on, in the case, groove portion 14 and the first bonding plane ST1 are in diameter It is adjacent upwards；Equally, plane where groove portion 14 can also be provided at is with the forward surface OP1 of axial parallel side 122 (that is, opposite The sagittal plane OP1-2 of face OP1) on, in the case, groove portion 14 and the first bonding plane ST1 are adjacent in the axial direction；Thus structure, It can prevent binder from overflowing to motor inside and to motor outside simultaneously, that is, to be arranged on the axial face OP1-1 of forward surface OP1 Groove portion 14 can prevent binder from overflowing on the outside of motor, and the groove portion 14 being arranged on the sagittal plane OP1-2 of forward surface OP1 can Prevent binder to spilling on the inside of motor.

In the present embodiment, Fig. 2 shows the sagittal plane OP1- of axial face OP1-1 and forward surface OP1 in forward surface OP1 The case where groove portion 14 are all set on 2, but the present embodiment is without being limited thereto, it can also be only in the axial face OP1-1 or phase of forward surface OP1 Groove portion 14 is set on the sagittal plane OP1-2 of face OP1；Wherein, groove portion 14 is arranged on the axial face OP1-1 of forward surface OP1 to compare Groove portion 14 is arranged on forward surface OP1-2 can preferably accommodate binder, to prevent binder due to gravity influences from slot It is overflowed in portion 14.

Fig. 4 is the diagrammatic cross-section of the another embodiment of the motor of the utility model embodiment 1；Fig. 5 is that this is practical The top view of the shell of the motor of new embodiment 1.

In the present embodiment, as shown in Figure 4 and Figure 5, side 122 has thinner wall section 1221 and with thinner wall section 1221 in circumferential direction Upper adjacent thick wall portion 1222, stage portion 123 are provided with protrusion 1231, direction support of the protrusion 1231 in stage portion 123 The surface 123a of frame 13 is axially protruded to bracket 13, and at least part of thinner wall section 1221 is located at protrusion 1231 in radial direction Upper opposed position, groove portion 14 are arranged on the forward surface OP1 of the thick wall portion 1222 of side 122.

Thus structure, since groove portion 14 is provided only on the forward surface OP1 of thick wall portion 1222, without being set in thinner wall section 1221 Groove portion 14 is set, therefore the durability degree of the side 122 of shell 12 can be enhanced.

In the present embodiment, Fig. 4 and Fig. 5 shows the axial face that the forward surface OP1 of thick wall portion 1222 is arranged in groove portion 14 Situation on OP1-1, but the present embodiment is without being limited thereto, and groove portion 14 can also be provided at the radial direction of the forward surface OP1 of thick wall portion 1222 On the OP1-2 of face.

In the present embodiment, as shown in Figure 4 and Figure 5, step recess portion 1232, step can also be set in stage portion 123 Recess portion 1232 is radially positioned between the inner peripheral surface of side 122 and the radially-outer surface of protrusion 1231.

Thus structure, step recess portion 1232 can be used for further accommodating to be glued along what the sagittal plane OP1-2 of forward surface OP1 overflowed Agent is tied, to prevent binder from reaching the inside of motor body 11, for example, preventing binder from reaching rotor.

In the present embodiment, as shown in Figure 4 and Figure 5, step recess portion 1232 can be opposed radially with thinner wall section 1221. Thus structure, due to groove portion 14 not being arranged in thinner wall section 1221, with the opposed step recess portion radially of thinner wall section 1221 1232 can accumulate the binder overflowed at (receiving) thinner wall section 1221.
