Referring to fig. 1 and 2, the embodiment of the present invention provides a motor 1000, including stator module 100 and end cover 200, stator module 100 includes stator core (not shown in the drawings), form plastic package shell 110 through injecting on stator core, plastic package shell 110 opens along stator module 100's axial one end and forms installing port 101, stator module 100 inboard is injectd the installation cavity 102 with installing port 101 intercommunication, installation cavity 102 is used for holding rotor subassembly (not shown in the drawings), the rotor subassembly rotates and locates in installation cavity 102, end cover 200's middle part position is equipped with the bearing groove, be used for installing rotor bearing, end cover 200 assembles the back that targets in place and covers in installing port 101, and can support rotor subassembly through rotor bearing, make rotor subassembly can steady operation.

Fig. 1 is a schematic structural diagram of the motor 1000 after assembly, and it can be understood that the motor 1000 further includes a wiring harness 300, where the wiring harness 300 may be composed of a power line, a signal line, and other conducting wires, and the wiring harness 300 needs to pass through the plastic package housing 110 and enter the interior of the plastic package housing 110, so that the wiring harness 300 can be electrically connected with components such as a circuit board in the mounting cavity 102, and therefore in the embodiment, the plastic package housing 110 is provided with the outlet 131, which is convenient for the wiring harness 300 to be led out through the outlet 131.

As can be understood from fig. 2, an end surface of the plastic package housing 110 at the mounting port 101 is a first end surface 111, a circumferential wall of the plastic package housing 110 extends in an 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, and the outlet 131 is disposed on the flange 130, so that the wiring harness 300 can be led out from an inner side of the flange 130 to an outer side through the outlet 131. And a wire clamp 400 is arranged at the outlet 131, the wire clamp 400 is matched with the outlet 131, and a wire can be clamped through the wire clamp 400. In addition, the periphery wall of plastic envelope shell 110 is equipped with installation foot 120, is connected with electrical equipment through installation foot 120, easy to assemble motor 1000.

It should be noted that, considering that application scenarios of products such as household appliances carrying the motor 1000 are more extensive, and the diversity of application environments of the motor 1000 is increased, in the design process of the motor 1000, attention needs to be paid to the waterproof problem under severe working conditions such as raining, and performance degradation of the motor 1000 and even abnormal operation caused by water entering from the position of the outlet 131 are avoided. Based on this, the embodiment of the utility model provides an assembly structure to fastener 400 and outlet 131 optimizes, effectively improves motor 1000's leakproofness, reduces the phenomenon that motor 1000 appears intaking, promotes motor 1000 operational reliability.

Referring to fig. 2 and 7, it can be understood that in some embodiments, the wire clamp 400 is an elastic member, preferably made of an elastic material, and may be made of a silicon rubber or a rubber material, the wire clamp 400 may clamp a conducting wire passing through the outlet 131, a plurality of wires form the wire harness 300, the wire harness 300 is integrally connected through the connecting terminal 310, and the wire clamp 400 fixes each wire, so that the wire harness 300 is integrally positioned. The wire clamp 400 is arranged 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 can also play a role in sealing.

Taking the embodiment shown in fig. 9 as an example for illustration, fig. 9 shows a schematic view of a state where the end cover 200 is not assembled, it can be 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 cover 200 is the third end surface 401, the height of the wire clip 400 is greater than the height of the outlet 131, and when the wire clip 400 is assembled in the outlet 131, the third end surface 401 protrudes relative to the second end surface 132, that is, in the state where the end cover 200 is not assembled, the upper end surface of the wire clip 400 is at the end surface of the flange 130 with a height difference therebetween. Because the hardness is small, the magnitude of interference exists between the end cover 200 and the wire clamp 400, after the end cover 200 is connected with the flange 130 and assembled in place, the end cover 200 extrudes the upper end face of the wire clamp 400, the wire clamp 400 deforms under the action of pressure, and the wire clamp 400 extrudes the inner wall of the wire outlet 131 towards the periphery, so that the contact surface of the wire clamp 400 and the wire outlet 131 is attached more tightly, a more effective sealing structure is formed, the sealing performance between the wire clamp 400 and the stator assembly 100 is improved, the risk that the motor 1000 enters water at the position of the wire outlet 131 is effectively reduced, and the operation reliability of the motor 1000 is improved.

Taking the wire clip 400 made of silicone rubber as an example for illustration, it can be understood in conjunction with fig. 9 that the wire clip 400 is formed by injection molding, and the protruding height of the third end surface 401 relative to the second end surface 132 is h in the embodiment, which satisfies the following conditions: h is more than or equal to 0.5mm, that is to say, the height difference between the second end surface 132 and the third end surface 401 needs to be more than or equal to 0.5mm, for example, the height difference can be 0.5mm, 1mm and the like, so that the end cover 200 can generate enough extrusion force to the wire clamp 400, the sealing performance is favorably improved, and the waterproof performance is greatly improved. It can be understood that if the height difference is too small, the amount of deformation generated by the clip 400 is too small, which affects the sealing property between the clip 400 and the outlet 131.

It should be noted that the elastic modulus of the clip 400 in the examples is e, and 1.2 MPa. Ltoreq. E.ltoreq.5.4 MPa (MPa) is satisfied. It will be appreciated that the elastic member will deform when an external force is applied to the elastic member, and the modulus of elasticity is understood to be the stress in a unidirectional stress state divided by the strain in that direction. In the elastic deformation stage of the material, the stress and the strain are in a proportional relation, the proportional coefficient is called elastic modulus, the index of the difficulty degree of the material in generating elastic deformation can be measured according to the elastic modulus, the larger the value of the proportional coefficient is, the larger the stress for enabling the material to generate certain elastic deformation is, namely the higher the rigidity of the material is, the smaller the elastic deformation is generated under the action of certain stress, and the index of the elastic deformation resistance of the material can be reflected. The elastic modulus of the wire clamp 400 is set to meet the condition that e is more than or equal to 1.2MPa and less than or equal to 5.4MPa, so that the wire clamp 400 has better elastic deformation capacity, and the wire clamp 400 is more tightly combined with the plastic package shell 110 under the condition of extrusion. Specific elastic modulus values can be selected according to different materials and application sealing requirements, for example, the elastic modulus e can be 1.2MPa, 2MPa and the like when the wire clamp 400 is a silica gel material, and the elastic modulus e can be 3MPa, 4MPa, 5.4MPa and the like when the wire clamp 400 is a rubber material, and the specific requirements are not limited.

It can be understood that the hardness of the wire clamp 400 in the embodiment is c, and satisfies: c is more than or equal to 30HA and less than or equal to 70HA, the specific hardness can be set according to the requirements of practical application scenes, the compression resistance of the wire clamp 400 can be reflected through the hardness, the smaller the hardness is, the more easy the wire clamp 400 is to deform, otherwise, the larger the hardness is, the more difficult the wire clamp 400 is to deform, and the sealing performance between the wire clamp 400 and the plastic package shell 110 can be influenced by the excessively small hardness or the excessively large hardness. When the wire clamp 400 deforms, the side wall of the wire clamp 400 and the side wall of the mounting groove 210 form a binding force of an over-hard fit, the wire clamp 400 adopts different hardness, and the binding force of the wire clamp 400 and the end cover 200 can also change. For example, the wire clip 400 may have a hardness of 30HA, 40HA, etc. when the wire clip 400 is a silicone material, and may have a hardness of 60HA, 70HA, etc. when the wire clip 400 is 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, the flange 130 is in interference fit with the mounting groove 210, so that the end cover 200 is connected with the flange 130 for fastening, and thus the first end cover 200 can be quickly assembled on the stator assembly 100 without additional auxiliary components for fixing, and 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 action of pressure and forms a seal with the plastic package housing 110.

In addition, referring to fig. 6, the outer circumferential wall of the wire clip 400 extends outward to form a limiting portion 420, when the wire clip 400 is fixed to the outlet 131, two sides of the limiting portion 420 can be clamped to the outer side wall of the flange 130, and an upper side of the limiting portion 420 can be clamped to the outer side wall of the end cap 200, so that the wire clip 400 can be prevented from shifting in the radial direction of the stator assembly 100, and the stability of the assembly structure of the wire clip 400 can be improved.

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

Referring to fig. 7, fig. 7 shows another embodiment of the wire clamp 400, in which the wire clamp 400 is provided with a wire through hole (not shown in the drawings), 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 through hole, and the wire harness sleeve 430 is integrally formed with the wire clamp 400, in the assembling process, after the wire harness 300 passes through the wire harness sleeve 430 and the wire through hole, the wire harness sleeve 430 is tightened by using a binding tape, so that the wire harness 300 is tightened by the wire harness sleeve 430, the sealing between the wire harness 300 and the wire clamp 400 is realized, and meanwhile, the wire clamp 400 is deformed after being assembled in place, so that the sealing is further formed at the wire through hole, and the better sealing performance is achieved.

Consider because fastener 400 has certain flexibility, there is not high problem of cohesion between pencil 300 and the fastener 400, the pencil 300 appears becoming flexible, draws the risk of taking off easily when receiving the exogenic action. Therefore, the utility model discloses motor 1000 sets up solidus structure 103 through being close to outlet 131 department at the first terminal surface 111 of plastic envelope shell 110, utilizes solidus structure 103 to fix pencil 300, makes pencil 300 obtain effectively fixed, can satisfy the sealed and fixed demand of pencil 300 through fastener 400 with solidus structure 103 cooperation like this, the greatly reduced pencil 300 appears becoming flexible when making pencil 300 receive the exogenic action, the risk of drawing off, the reliability of motor 1000 has been promoted.

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 formed 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, and may be four or more, which is not particularly limited.

It should be noted that, as shown in 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 integrally L-shaped, one end port of the first wire groove 141 is located on a side wall of the boss close to the wire outlet 131, and the other end port 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 a wire is correspondingly placed into the first wire groove 141, the wire can be bent along the first wire groove 141 to form a curved line body, that is, the groove body of the first wire groove 141 is not a straight groove, which is beneficial to increase the frictional resistance between the wire and the groove body, so that the wire is not easily separated 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 also be provided, and the bending angle is also 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 the two bending sections 142, the bending angle range may be in a range from 90 ° to 180 °, and it should be noted that when the wire is bent to form 180 °, the wire forms two parallel wire bodies. It can be understood that the more the quantity of the bending sections 142, the larger the bending angle, the larger the frictional resistance between the wire and the groove body, the more difficult the wire is to break away from the first wire groove 141, and after each wire is fixed at the corresponding first wire groove 141, the more effective fixation of the whole wire harness 300 can be realized, and the risk that the wire harness 300 becomes loose and is pulled off is greatly reduced.

It can be understood that the protruding rib 143 can abut against the wire inside the groove body, so that the wire and the first wire groove 141 are in an interference fit assembly structure, and the firmness of the wire is further increased.

It should be noted that the height of the protrusion of the rib 143 can be set according to the wire diameter of the wire, so as to avoid excessive extrusion damage to the wire due to the too high rib 143. In addition, in the embodiment, 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, 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 wiring harness 300 of the power line as an example, the wiring harness 300 is firstly 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 rib 143 to achieve the purpose of interference fit, each wire in the wiring harness 300 is fixed, and the wiring harness 300 is effectively prevented from loosening.
