The following description of the embodiments of the present invention will be made with reference to the accompanying drawings, in which it is apparent that the embodiments described below are some, but not all embodiments of the invention.

A motor 1000 according to an embodiment of the present invention, which is a brushless motor in particular, is described with reference to fig. 1 to 9, and is applied to a home appliance apparatus such as an air conditioner, and the motor 1000 will be described below with a specific example.

Referring to fig. 1 and 2, an electric motor 1000 provided by an embodiment of the present invention includes a stator assembly 100 and an end cover 200, the stator assembly 100 includes a stator core (not shown in the drawings), a plastic package housing 110 is formed on the stator core by injection molding, one end of the plastic package housing 110 along an axial direction of the stator assembly 100 is opened to form a mounting opening 101, a mounting cavity 102 communicating with the mounting opening 101 is defined at an inner side of the stator assembly 100, the mounting cavity 102 is used for accommodating a rotor assembly (not shown in the drawings), the rotor assembly is rotatably disposed in the mounting cavity 102, a bearing groove is disposed in a middle position of the end cover 200 and is used for mounting a rotor bearing, the end cover 200 is covered on the mounting opening 101 after being assembled in place, and the rotor assembly can be supported through the rotor bearing, so that the rotor assembly can stably operate.

Fig. 1 is a schematic structural diagram of an assembled motor 1000, and it can be understood that the motor 1000 further includes a wire harness 300, the wire harness 300 may be formed by wires such as a power line and a signal line, and the wire harness 300 needs to pass through the plastic package housing 110 to enter the interior, so that the wire harness 300 can be electrically connected with components such as a circuit board in the mounting cavity 102, and therefore, in an embodiment, an outlet 131 is provided on the plastic package housing 110, so that the wire harness 300 is convenient to perform wire outgoing through the outlet 131.

As can be understood from fig. 2, the end surface of the plastic package housing 110 at the mounting opening 101 is a first end surface 111, the peripheral wall of the plastic package housing 110 extends along the axial direction of the stator assembly 100 to form a flange 130 protruding from the first end surface 111, the flange 130 is generally annular as a whole, and the wire outlet 131 is disposed on the flange 130, so that the wire harness 300 can be led out from the inner side of the flange 130 through the wire outlet 131 to the outer side. And a wire clamp 400 is provided at the outlet 131, the wire clamp 400 being matched with the outlet 131, and a wire can be clamped by the wire clamp 400. In addition, the outer peripheral wall of the plastic package housing 110 is provided with mounting feet 120, and the motor 1000 is conveniently mounted by connecting the mounting feet 120 with electrical equipment.

It should be noted that, considering that the application scenario of products such as home appliances carrying the motor 1000 is wider, the diversity of the application environment of the motor 1000 is also increased, so that the waterproof problem under the severe working conditions such as rain needs to be focused in the design process of the motor 1000, and the performance of the motor 1000 is prevented from being reduced or even the motor cannot work normally due to water entering the position of the outlet 131. Based on this, the embodiment of the invention optimizes the assembly structure of the wire clamp 400 and the wire outlet 131, effectively improves the tightness of the motor 1000, reduces the water inlet phenomenon of the motor 1000, and improves the operation reliability of the motor 1000.

Referring to fig. 2 and 7, it will be appreciated that in some embodiments, the wire clip 400 is an elastic member, preferably made of a material having elasticity, and may be specifically made of silica gel or rubber, the wire clip 400 may clamp a wire passing through the outlet 131, a plurality of wires form the wire harness 300, the wire harness 300 is integrally connected through the connection terminal 310, and the wire clip 400 fixes each wire, so that the wire harness 300 is integrally positioned. The wire clamp 400 is installed in the wire outlet 131, and the wire clamp 400 is deformed and tightly attached to the inner wall of the wire outlet 131 to form a sealing structure by extruding the wire clamp 400, so that the wire clamp 400 and the plastic package shell 110 are effectively sealed, and the wire clamp 400 can fix the wire harness 300 and also can play a sealing role.

Taking the embodiment shown in fig. 9 as an example for illustration, fig. 9 shows a schematic view of a state in which the end cap 200 is not assembled, it is understood that the upper end surface of the flange 130 is the second end surface 132, the end surface of the wire clip 400 facing the end cap 200 is the third end surface 401, and the height of the wire clip 400 is greater than the height of the wire outlet 131, and when the wire clip 400 is assembled into the wire outlet 131, the third end surface 401 protrudes with respect to the second end surface 132, that is, in a state in which the end cap 200 is not assembled, the upper end surface of the wire clip 400 is located at the end surface of the flange 130 with a height difference therebetween. Because hardness is less, there is the interference between end cover 200 and the fastener 400, after end cover 200 is connected with flange 130 and is assembled in place, end cover 200 produces the extrusion to the up end of fastener 400, make fastener 400 take place deformation under the pressure effect, fastener 400 can extrude the inner wall of outlet 131 all around, thereby make fastener 400 and the contact surface laminating of outlet 131 more inseparable, form more effective seal structure, improve the leakproofness between fastener 400 and the stator module 100, effectively reduce the risk that motor 1000 appears intaking in the position of outlet 131, promote motor 1000 operational reliability.

Taking the wire clip 400 made of a silicone material as an example for illustration, it can be understood with reference to fig. 9 that the wire clip 400 is formed by an injection molding process, and in the embodiment, the protruding height of the third end surface 401 relative to the second end surface 132 is h, which satisfies the following requirements: h is equal to or greater than 0.5mm, that is, the difference in height between the second end surface 132 and the third end surface 401 needs to be equal to or greater than 0.5mm, for example, the difference in height may be 0.5mm, 1mm, etc., so that the end cover 200 can generate a sufficient extrusion force on the wire clip 400, which is favorable for improving the sealing performance and greatly improves the waterproof performance. It can be appreciated that if the height difference is too small, the deformation amount of the wire clip 400 is too small, which affects the tightness between the wire clip 400 and the outlet 131.

In the embodiment, the elastic modulus of the line clamp 400 is e, and the elastic modulus is 1.2 MPa.ltoreq.e.ltoreq.5.4 MPa (megapascals). It is understood that an external force is applied to the elastic member, the elastic member is deformed, and the elastic modulus is understood as the stress divided by the strain in that direction in the unidirectional stress state. In the elastic deformation stage, the stress and the strain of the material are in a proportional relation, the proportional coefficient is called elastic modulus, the index of the degree of difficulty in generating elastic deformation of the material can be measured according to the elastic modulus, and the larger the value is, the larger the stress of the material for generating certain elastic deformation is, namely the larger the rigidity of the material is, namely the smaller the elastic deformation is under the action of certain stress, so that the index of the elastic deformation resistance of the material can be reflected. By setting the elastic modulus of the wire clamp 400 to be 1.2 MPa-5.4 MPa, the wire clamp 400 has better elastic deformation capability, and the wire clamp 400 is tightly combined with the plastic package shell 110 under the condition of being extruded. Specific elastic modulus values can be selected according to different materials and requirements of application tightness, for example, the elastic modulus e can be 1.2MPa, 2MPa and the like when the wire clamp 400 is made of a silica gel material, and the elastic modulus e can be 3MPa, 4MPa, 5.4MPa and the like when the wire clamp 400 is made of a rubber material, and the specific elastic modulus is not limited.

It will be appreciated that the hardness of the wire clip 400 is c in the illustrated embodiment, and is: the specific hardness can be set according to the actual application scene requirement, the compressive capacity of the wire clamp 400 can be reflected through the hardness, the smaller the hardness is, the more easily deformed the wire clamp 400, the larger the hardness is, the more difficultly deformed the wire clamp 400 is, and the sealing performance between the wire clamp 400 and the plastic package shell 110 can be influenced by the excessively small or excessively large hardness. When the wire clip 400 is deformed, the side wall of the wire clip 400 and the side wall of the mounting groove 210 form a bonding force of excessively hard fit, the wire clip 400 adopts different hardness, and the bonding force with the end cover 200 is also changed. For example, the hardness of the clip 400 may be 30HA, 40HA, or the like when the clip 400 is made of a silicone material, and 60HA, 70HA, or the like when the clip 400 is made of a rubber material, which is not particularly limited.

It should be noted that, as can be understood from fig. 6, the edge of the end cover 200 is bent along the circumferential direction to form an annular mounting groove 210, and the flange 130 is in interference fit with the mounting groove 210, so that the end cover 200 is connected with the flange 130 to fasten, and therefore, the first end cover 200 can be quickly assembled to the stator assembly 100, no additional auxiliary component is needed to be used for fixing, the operation is simple and convenient, after the end cover 200 is assembled in place, the bottom surface of the mounting groove 210 abuts against the second end surface 132, and the wire clamp 400 is deformed under the pressure and forms a seal with the plastic package housing 110.

In addition, referring to fig. 6, the outer peripheral wall of the wire clip 400 is formed with a limiting portion 420 extending outwards, when the wire clip 400 is fixed to the wire outlet 131, two sides of the limiting portion 420 may be clamped to the outer side wall of the flange 130, and an upper side of the limiting portion 420 may be clamped to the outer side wall of the end cover 200, so that the wire clip 400 is prevented from being deviated in the radial direction of the stator assembly 100, and stability of an assembly structure of the wire clip 400 is improved.

It should be noted that, referring to fig. 2, in the embodiment, the wire clip 400 is provided with three clamping grooves 410, the three clamping grooves 410 and the wire clip 400 are integrally formed, when the wire clip 400 is assembled, a wire can be placed into the clamping groove 410 from the top wall of the wire clip 400, after the wire clip 400 is assembled to the wire outlet 131 to generate deformation, the wire clip 400 can be tightly clamped in the clamping groove 410, and an effective sealing structure is formed, so that water is prevented from entering the motor 1000 from the clamping groove 410.

Referring to fig. 7, in another embodiment of the wire clamp 400 shown in fig. 7, in this embodiment, a wire hole (not shown in the drawing) is formed in the wire clamp 400, the outer side wall of the wire clamp 400 protrudes to form a wire harness sleeve 430, the wire harness sleeve 430 is communicated with the wire hole, the wire harness sleeve 430 and the wire clamp 400 are integrally formed, in the assembly process, after the wire harness 300 passes through the wire harness sleeve 430 and the wire hole, the wire harness sleeve 430 is fastened by using a binding belt, the wire harness sleeve 430 is fastened to fasten the wire harness 300, so that sealing between the wire harness 300 and the wire clamp 400 is achieved, and meanwhile, the wire clamp 400 is deformed to form sealing at the wire hole further, so that better sealing performance is achieved.

Considering that the wire clip 400 has a certain flexibility, there is a problem that the binding force between the wire harness 300 and the wire clip 400 is not high, and the wire harness 300 is easy to loose and pull off when being subjected to external force. Therefore, in the motor 1000 of the embodiment of the invention, the wire fixing structure 103 is arranged at the position, close to the wire outlet 131, of the first end face 111 of the plastic package housing 110, and the wire harness 300 is fixed by the wire fixing structure 103, so that the wire harness 300 is effectively fixed, the requirements of sealing and fixing the wire harness 300 can be met through the cooperation of the wire clamp 400 and the wire fixing structure 103, the risk that the wire harness 300 is loosened and pulled off under the action of external force is greatly reduced, and the reliability of the motor 1000 is improved.

Referring to fig. 2 and 3, in some embodiments, the wire fixing structure 103 is a first boss 140 formed on the first end surface 111 of the plastic package housing 110, three first wire grooves 141 are provided on the first boss 140, the three first wire grooves 141 are arranged at intervals on the upper end surface of the first boss 140, and each first wire groove 141 is matched with a single wire of the wire harness 300, that is, three wires can be fixed simultaneously through the three first wire grooves 141. Of course, the number of the first wire grooves 141 may be set according to the number of wires of the wire harness 300, or four or more may be provided, not particularly limited.

It should be noted that, referring to fig. 3 and fig. 4, the groove body of each first wire groove 141 is provided with a bending section 142, so that the first wire groove 141 is an L-shaped groove body as a whole, one end port of the first wire groove 141 is located on the side wall of the boss close to the wire outlet 131, and the other end port of the first wire groove is located on the other side wall of the first boss 140, in the embodiment shown in fig. 3, the bending angle of the bending section 142 is 90 °, it can be understood that after the wire is correspondingly placed in the first wire groove 141, the wire is bent along the first wire groove 141 to form a bent wire body, that is, the groove body of the first wire groove 141 is not a straight groove, which is favorable for increasing the friction resistance between the wire and the groove body, so that the wire is not easy to separate from the first wire groove 141.

It should be noted that the number of the bending sections 142 of the first wire groove 141 is not limited to one, two or more bending sections 142 may be provided, and the bending angle is not limited to 90 °, for example, a U-shaped groove body may be formed by the bending sections 142, or an S-shaped groove body may be formed by matching two bending sections 142, and the bending angle may range from 90 ° to 180 °, and it should be noted that when the bending forms 180 °, the wire forms two mutually parallel wire bodies. It can be understood that, the more the number of the bending sections 142 is, the larger the bending angle is, the larger the friction resistance between the wires and the groove body is, the wires are difficult to separate from the first wire groove 141, and after each wire is fixed in the corresponding first wire groove 141, the whole wire harness 300 can be more effectively fixed, so that the risk of loosening and pulling out the wire harness 300 is greatly reduced.

With continued reference to fig. 3, in the embodiment, the side walls of each first slot 141 are respectively provided with a plurality of ribs 143, and the plurality of ribs 143 are disposed at intervals along the length direction of the slot, specifically, the plurality of ribs 143 may be staggered on two opposite side walls, and the number of the ribs 143 may be set according to the length of the slot body, which is not limited specifically. It can be appreciated that the protruding ribs 143 can abut against the wires in the groove body, so that the wires and the first wire groove 141 generate an interference fit assembly structure, and the firmness of the wires is further increased.

It should be noted that, the height of the protrusion of the protruding rib 143 can be set according to the wire diameter of the wire, so as to avoid excessive extrusion damage to the wire caused by too high protruding rib 143. In addition, the depth of the first wire groove 141 is set to be greater than or equal to 1.5 times the wire diameter of the wire in the embodiment, so that the wire can be further prevented from being separated from the first wire groove 141, for example, the depth of the first wire groove 141 is 3 times the wire diameter of the wire.

Taking the wire harness 300 of the power line as an example, the wire harness 300 is fixed on the wire clamp 400, and then each wire is correspondingly fixed in the first wire groove 141, so that the wire body is bent and matched through the convex ribs 143, the purpose of interference fit is achieved, each wire in the wire harness 300 is fixed, and the wire harness 300 is effectively prevented from loosening.

As can be understood from fig. 6, after the wires are placed in the second wire slot 151, the fixing plate 160 is used to cover the second boss 150, and the protruding blocks 161 correspondingly compress the wires in the slot body, so as to fix the wire harness 300, so that the whole wire harness 300 can be more effectively fixed, and the risk of loosening and pulling out the wire harness 300 is greatly reduced. It should be noted that, the second wire grooves 151 are arranged obliquely, so as to facilitate the routing of the wires, and the arrangement mode of the second wire grooves 151 is not particularly limited.
