When fool-proof protrusion 52 is installed in fool-proof hole 2212, in order to make the free ends of at least two cantilevers 521 close to each other, as shown in fig. 10, along the direction of inserting fool-proof protrusion 52 into fool-proof hole 2212, the outer surface of boss 523 is inclined toward the center line of fool-proof protrusion 52, and the side wall of fool-proof hole 2212 applies a force perpendicular to the outer surface of boss 523, so as to realize the effect of squeezing the free ends of at least two cantilevers 521, so that connecting neck 522 can smoothly enter fool-proof hole 2212, and the pre-installation of wiring assembly 5 or support plate 22 can be realized by the simple pushing action of an operator.

As shown in fig. 11, the first terminal 51 is a male terminal, the second terminal 2211 is a female terminal, the inner circumferential surface of the female terminal is arranged in a wave shape, the male terminal is inserted into the female terminal, the outer circumferential surface of the male terminal is connected with the inner circumferential surface of the female terminal through solder, and the inner circumferential surface of the female terminal is in the wave shape, so that the contact area between the inner circumferential surface of the female terminal and the solder is increased, and the welding between the male terminal and the female terminal is firmer.

The conventional stator core 211 is basically formed by punching silicon steel sheets and then laminating the silicon steel sheets, and because the silicon steel sheets have higher cost, the magnetic density of the stator core 211 is easily saturated, and meanwhile, the eddy current loss is higher, the silicon steel sheets have no performance and cost advantages when being used as the material of the conventional stator core 211.

Soft Magnetic Composite Material (SMC) is a high-purity iron powder Material with an inorganic insulating layer on the surface, can be made into the shape of the stator core 211 after pressing and heat treatment, has the characteristics of high saturation Magnetic induction and very low eddy current loss, and has performance and cost advantages when being used as a substitute for the original silicon steel sheet laminated stator core 211. The strength of the material of the stator core 211 formed by pressing iron powder is limited, and the situation that a part of the structure with poor strength is loose can occur under the conditions of long-time impact, vibration and the like, so that the application of the material to a motor is limited, and the application of the material to the compressor industry is further limited. In order to solve the above problem, as shown in fig. 12, the stator core assembly 21 generally further includes a reinforcing member 212, an accommodating space is disposed inside the reinforcing member 212, the core 211 is placed in the accommodating space, the reinforcing member 212 is a closed cover body capable of completely covering the stator core 211, and the reinforcing member 212 is configured to overcome a defect of poor structural strength of a soft magnetic composite material in the conventional stator core 211. However, when the rotor assembly 3 rotates relative to the stator 2, the stator core 211 generates more heat, and the stator core 211 is easily damaged due to a high temperature environment, so that the service life of the stator core assembly 21 is short, and the normal use of the motor 100 is affected. In order to solve the above problem, as shown in fig. 14, the reinforcing member 212 is provided with a heat dissipating opening 212211, so that when the rotor assembly 3 rotates relative to the stator 2, a large amount of heat generated by the stator core 211 can be discharged from the heat dissipating opening 212211, thereby preventing the stator core 211 from being damaged due to an excessively high temperature at the stator core 211 and prolonging the service life of the stator core 211.

Now, the structure of the motor 100 will be described with reference to an external rotor motor, and in order to facilitate understanding of the structure of the stator core 211, as shown in fig. 13, the stator core 211 includes a stator core body 2111 and a winding portion 2112 provided thereon, and the stator winding 213 is wound on the winding portion 2112. The winding portion 2112 has a T-shape, a small end of the winding portion 2112 is connected to the stator core body 2111, a large end of the winding portion 2112 is distant from the stator core body 2111, the stator winding 213 is provided between the large end of the winding portion 2112 and the stator core 2111, and the large end of the winding portion 2112 can prevent the winding portion 2112 from coming off the winding portion 2112.

To facilitate understanding of the specific structure of the reinforcing member 212, as shown in fig. 14, the reinforcing member 212 includes a first reinforcing portion 2121 and a second reinforcing portion 2122, a first accommodating space 21211 is provided in the first reinforcing portion 2121, the stator core body 2111 is disposed in the first accommodating space 21211, the second reinforcing portion 2122 is connected to the first reinforcing portion 2121, a second accommodating space 21221 is provided in the second reinforcing portion 2122, and a portion of the winding portion 2112 is disposed in the second accommodating space 21221, so that the reinforcing member 212 can provide a better protection effect for the stator core body 2111 disposed therein. Specifically, the reinforcement 212 is through the periphery of moulding plastics integrated into one piece at stator core 211, can realize the more firm cladding effect of reinforcement 212 to stator core 211, avoids reinforcement 212 to drop from stator core 211, realizes the better guard action of reinforcement 212 to stator core 211. In addition, the reinforcing member 212 and the stator core 211 are preassembled to be a whole, so that the stator core assembly 21 and the rotor assembly 3 are conveniently installed, and the assembly efficiency of the motor 100 is improved.

The air gap is a gap formed between the stator 2 and the rotor assembly 3, the air gap is a non-magnetic part of a magnetic circuit, and if the free end of the winding portion 2112 wraps the upper reinforcing member 212, the air gap between the stator 2 and the rotor assembly 3 is large, and the larger the leakage magnetic flux is, the smaller the mutual magnetic flux is, and the electromotive force, the current and the torque of the rotor assembly 3 are reduced. In order to solve the above problem, as shown in fig. 14, a heat dissipating hole 212211 is formed at an end of the second reinforcing portion 2122 away from the first reinforcing portion 2121, and a free end of the winding portion 2112 away from the stator core body 2111 is located at or protrudes out of the heat dissipating hole 212211, so that an air gap is reduced, leakage flux is reduced, mutual magnetic flux is increased, and electromotive force, current, and torque of the rotor assembly 3 are increased due to the elimination of the thickness of the non-magnetic reinforcing member 212 between the free end of the winding portion 2112 and the rotor assembly 3.

Preferably, in order to further prevent the stator winding 213 from falling off the reinforcement member 212 and ensure the normal operation of the motor 100, as shown in fig. 14 and 15, the second reinforcement part 2122 includes a reinforcement part body 21222 and a limiting structure 21223, the second accommodating space 21221 is provided on the stator core body 2111, the stator winding 213 is wound around the periphery of the reinforcement part body 21222, the limiting structure 21223 is provided at the upper end and/or the lower end of the reinforcement part body 21222 and is located at a side of the reinforcement part body 21222 away from the first reinforcement part 2121, and the limiting structure 21223 is used for limiting the stator winding 213 from falling off the reinforcement part body 21222.

The narrow end portion of the T-shaped winding portion 2112 has a generally rectangular longitudinal section, and when the stator winding 213 is wound around the narrow end, the winding portion 2112 forms a 90-degree corner at the corner position of the narrow end, which causes an excessively large bending width of the winding portion 2112, and tends to cause a breakage phenomenon of the wire inside the winding portion 2112. In order to solve the above problem, as shown in fig. 16, the second reinforcing part 2122 further includes a supporting structure 21224, the supporting structure 21224 is disposed at the upper end and/or the lower end of the reinforcing part body 21222 and is located between the limiting structure 21223 and the first reinforcing part 2121, the width of the supporting structure 21224 is smaller than the width of the reinforcing part body 21222, the reinforcing part body 21222 and the supporting structure 21224 jointly support and mount the stator winding 213, and an included angle between branch lines of two adjacent stator windings 213 is an obtuse angle, so that a bending range formed at a corner position of the winding part 2112 is small, the wire inside the winding part 2112 is not broken, normal conduction of the wire inside the winding part 2112 is ensured, and normal use of the motor 100 is ensured.

As shown in fig. 16, in order to further reduce the bending degree of the diagonal portion 2112 at the corner, the support structure 21224 is strip-shaped, the support structure 21224 extends along the length direction of the reinforcing portion body 21222, and the corner position of one end of the support structure 21224 away from the reinforcing portion body 21222 is a circular arc surface. Preferably, the end surface of the support structure 21224 away from the reinforcing portion body 21222 is a circular arc surface, which can further prevent the winding portion 2112 from bending to a large extent, and prevent the wire inside the stator winding 213 from being broken.

As shown in fig. 1 and 17, the casing 1 is provided with an air inlet 121 and an air outlet 122, and an air exhaust passage 400 is formed between the lower surface of the fan mechanism 200 and the air outlet 122. In order to exhaust the gas generated by the heat exchange system into the vehicle, the output end of the motor 100 extends out of the exhaust port 122, the output end of the motor 100 is connected with the fan mechanism 200, when the motor 100 is started, the output end of the motor 100 rotates and drives the fan mechanism 200 to rotate, and the fan mechanism 200 forms an air pressure difference around the fan mechanism to drive the gas to flow, so that the gas after heat exchange is exhausted into the vehicle. In addition, because motor 100 can produce more heat at the in-process of work, higher temperature can influence the normal work of motor 100, so part lets in air inlet 121 through fan mechanism 200 exhaust flow at first, the air current discharges outside the air-blower through gas vent 122 and exhaust passage 400 in proper order behind motor 100, thereby realize the cooling effect to motor 100, guarantee motor 100's normal use, but because the inside and outside pressure differential of casing 1 is less, the flow power of air current is relatively poor, the air current is relatively poor to motor 100's cooling effect.

In order to solve the above problem, as shown in fig. 17 and 3, a plurality of first blades 204 are arranged on a surface of the fan mechanism 200 opposite to the motor 100 at intervals along a circumferential direction of the fan mechanism 200, and when the fan mechanism 200 rotates with the motor 100, the first blades 204 can generate negative pressure near the first blades, so that an airflow entering from the air inlet 3021 passes through the windings of the motor 100 more smoothly and in a larger amount, and then is discharged from the air outlet 3022 and the air discharge passage 400, which can improve a cooling effect of the airflow on the windings of the motor 100, avoid an excessively high temperature of the motor 100, and ensure a better operation of the motor 100.

In order to discharge more air flow through the inside of the motor 100 and achieve a better cooling effect on the inside of the motor 100, as shown in fig. 3 and 18, a heat dissipation opening 311 is formed in the top end of the cover 31, the air flow entering from the air inlet 121 enters the motor 100 from a gap between the stator 2 and the rotor assembly 3, and the air flow cools the inside of the motor 100 and then is discharged out of the blower through the heat dissipation opening 311, so that the cooling of the air flow on the inside of the motor 100 is achieved, and the cooling effect of the air flow on the motor 100 is improved.

In order to enable most of the airflow to pass through the inside of the motor 100 and then be discharged out of the blower, and improve the utilization rate of the airflow, as shown in fig. 3, at least a portion of the motor 100 is located at the exhaust port 122, as shown in fig. 3 and fig. 19, the first blade 204 includes a blade body 2041 and a blocking plate 2042, the blade body 2041 extends from the axis of the fan mechanism 200 to the periphery of the fan mechanism 200, the blocking plate 2042 extends from the outer end of the blade body 2041 toward the motor 100, the blocking plate 2042 is inserted between the motor 100 and the housing 1, the blocking plate 2042 can prevent the airflow that does not pass through the inside of the motor 100 from being directly discharged out of the exhaust port 122, so that the utilization rate of the airflow is improved, it is ensured that most of the airflow passes through the inside of the motor 100 and then is discharged out of the blower, and the cooling effect of the airflow on the motor 100 is improved.

To facilitate understanding of the fan mechanism 200, a specific structure of the fan mechanism 200 will now be described with reference to fig. 19. As shown in fig. 19, the fan mechanism 200 further includes a downward-opening cover 201, a plurality of second blades 202, and a support ring 203, the first blades 204 are disposed on a lower surface of the cover 201, the second blades 202 extend upward from a bottom edge of the cover 201, the plurality of second blades 202 are disposed around a circumference of the cover 201, and upper ends of the plurality of second blades 202 are connected to the support ring 203. The stability of the overall structure of the fan mechanism 200 can be improved by providing the support ring 203, and the top ends of the second blades 202 are prevented from swinging when the fan mechanism 200 rotates.

Since the second blade 202 functions to discharge the air flow near the fan mechanism 200 to the outside of the blower and the first blade 204 functions to suck the air flow outside the blower to the inside of the motor 100, as shown in fig. 20, the first blade 204 and the second blade 202 each have an arc shape and the first blade 204 and the second blade 202 are bent in opposite directions.

As shown in fig. 17, the housing 201 of the prior art is in a horn shape, and the side 2011 of the longitudinal section of the housing 201 is an arc line bent toward the motor 100, but in practical use, the air discharge amount of the fan mechanism 200 with such a structure is small, and if the air discharge amount of the fan mechanism 200 with such a structure is to be increased, the whole fan mechanism 200 needs to be made large, so that the volumes of the fan mechanism 200 and the blower are large, and the blower cannot be installed in a space with a compact structure, and the use of the blower is limited. The inventors have conducted extensive research and research, and found that the above problem occurs because the volume of the space between the second blade 202 and the housing 201 is too small, and thus the amount of air discharged from the fan mechanism 200 is small. In order to solve the above problem, as shown in fig. 3, the outer cover 201 is in a horn shape, a side 2011 of a longitudinal section of the outer cover 201 is an arc line, and the side 2011 is curved towards a side of the outer cover 201 away from the motor, when the external shape of the fan mechanism 200 in fig. 3 and 17 is consistent in size, because the volume between the outer cover 201 and the second blade 202 of the present embodiment is larger than the volume between the outer cover 201 and the second blade 202 in fig. 17, the large air volume discharged outside by the fan mechanism 200 can be realized, the fan mechanism 200 of the present embodiment can achieve the effect of small volume and large displacement, and is conveniently applied to an environment with a small space.
