Specific embodiment
It is specific below in conjunction with the utility model to keep the purpose of this utility model, technical solution and advantage clearer
Technical solutions of the utility model are clearly and completely described in embodiment and corresponding attached drawing.Obviously, described embodiment
It is only the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, this field
Those of ordinary skill's every other embodiment obtained without making creative work, belongs to the utility model
The range of protection.
As shown in Figure 1, a kind of end cover mounting structure of motor, including：End cap 1, connection ring 2 and field frame assembly 3.Connection ring
2 are fixedly connected on field frame assembly 3, end cap 1 it is identical with the material of connection ring 2 (such as end cap 1 and connection ring 2 be all made of it is zinc-plated
Iron plate production), end cap 1 is inserted into connection ring 2, and is interference fitted with connection ring 2, and end cap 1 is fixed on field frame assembly 3
On.Specifically can be as shown in the figure, the insertion section 11 that there is end cap 1 shape and 2 inner hole of connection ring to match, and insertion section 11
It is inserted into connection ring 2, and is interference fitted with the inner hole of connection ring 2.Since end cap 1 is identical with the material of connection ring 2, in identical ring
Border temperature and humidity variation under, the shrinking percentage of the two is identical, no matter therefore environment temperature how to change with humidity, end cap 1 and company
Connect the connection status that ring 2 can be always maintained at interference fit, can make in this way the connection between end cap and field frame assembly it is more stable,
Reliably, it avoids loosening therebetween.
In actual fabrication, as shown in figure 8, having mounting groove 31 on field frame assembly 3, connection ring 2 is fixedly connected on installation
On the side wall of slot 31, that is to say, that end cap 1 is fixedly mounted on the mounting groove 31 of field frame assembly 3 by connection ring 2, needs to illustrate
, mounting groove 31 is connected to the inner cavity of field frame assembly 3 in actual fabrication, that is to say, that end cap 1 is fixedly mounted on mounting groove
It can be realized the closing of the inner cavity to field frame assembly 3 on 31.Wherein, mounting groove 31 can be cylinder, and connection ring 2 is and peace at this time
The circular ring shape that tankage 31 matches only needs to guarantee it is not limited to this, mounting groove 31 may be the other shapes such as prismatic
The shape of connection ring 2 matches with it.
Further, as shown in Fig. 2 to 6, there is reinforcing rib 21 circumferentially on the periphery wall of connection ring 2.This
Sample can be improved the intensity of connection ring 2 itself, avoid the phenomenon that end cap 1 loosens occur because it is deformed.Specifically, it connects
The first frame mode can be used in ring 2, and as shown in Figure 2,3, the quantity of reinforcing rib 21 is one, and the setting of reinforcing rib 21 is even
The axial one end of ring 2 is connect, enables that connection ring 2 is cut into L-shaped section by the plane of 2 axis of connection ring.More preferably, it connects
Second of frame mode can be used in ring 2, and as shown in Figure 4,5, 6, the quantity of reinforcing rib 21 is two, and two reinforcing ribs 21 divide
The axial both ends of connection ring 2 are not set, the section that connection ring 2 is cut into U-shaped by the plane of 2 axis of connection ring is enable.
It should be noted that the quantity of reinforcing rib 21 is not limited in one or two, setting number can also be increased as the case may be
Amount.
As an embodiment, as shown in Figure 2,4, have allow conducting wire to pass through to cross line notch 24 in connection ring 2.
The Hall Plate power supply line inside field frame assembly 3 can be enable to stretch out by crossing line notch 24 in this way, do not needed in field frame assembly 3
Or cable-through hole is separately set on end cap 1, save cost of manufacture.In actual fabrication, crosses line notch 24 and disconnect connection ring 2, make
Connection ring 2 has mutually separated first end 25 and second end 26.When connection ring 2 is circular ring shape, the center of line notch 24 is crossed
Angle is α, and the specific angle value in 15 °≤α≤60 ° can be determined according to the wire diameter and quantity passed through.It can either guarantee in this way
The stability being cooperatively connected between end cap 1 and connection ring 2, while it is too small and influence conducting wire and pass through to can be avoided line notch 24.
When specifically making, connection ring 2 can be directly placed into the injection mold of field frame assembly 3, and connection ring 2 is led to
The mode for crossing injection molding is integrally formed on the side wall of mounting groove 31.So not only be easy production, while can guarantee connection ring 2 with
The fastness connected between field frame assembly 3.
As an embodiment, the connection between connection ring 2 and field frame assembly 3 can further include connecting as shown in 7 to 10
Connect screw 4；As shown in Figure 9, it is provided with connection through-hole 22 in connection ring 2, have as shown in Figure 8, on field frame assembly 3 and connects
The corresponding connecting screw hole 32 in hole 22 is connected, attachment screw 4 passes through connection through-hole 22 and is threaded in connecting screw hole 32, with
Connection ring 2 is fixed on field frame assembly 3.
To two kinds of link positions of attachment screw 4 are introduced respectively in the present embodiment, the first link position such as Fig. 7
Shown in 9, there is mounting groove 31 on field frame assembly 3, at this time as shown in Figure 9, the side wall of connection ring 2 is arranged in connection through-hole 22
On, as shown in Figure 8, connecting screw hole 32 is arranged on the side wall of mounting groove 31.Further, as shown in figure 8, connection ring 2 is carried on the back
To bit-avoiding slot 23 is provided on the surface of field frame assembly 3, connection through-hole 22 is arranged on the bottom surface of bit-avoiding slot 23, and along connection
In the axial direction of through-hole 22, the depth of bit-avoiding slot 23 is greater than the length of the head of screw of attachment screw 4.In this way when attachment screw 4 will be even
When connecing ring 2 and being fixed on the side wall of mounting groove 31, the head of screw of attachment screw 4 can be completely hidden in bit-avoiding slot 23, will not
The inner surface of connection ring 2 is protruded from, and then avoids interfering with the insertion section 11 of the end cap 1 of insertion connection ring 2.Second of company
It is as shown in Figure 10 to connect position, reinforcing rib 21 is set in connection ring 2, connection through-hole 22 is arranged on reinforcing rib 21, connecting screw hole 32
It is arranged on the end face of field frame assembly 3.It should be noted that no matter attachment screw 4 is in which link position, attachment screw 4
Quantity can be at least two, and the quantity for connecting through-hole 22 can be at least two and, company uniformly distributed along the circumferential direction of connection ring 2
It is equal with the connection quantity of through-hole 22 and correspond to connect the quantity of screw hole 32, the quantity of attachment screw 4 and connecting screw hole 32 with
And the quantity of connection through-hole 22 is equal and correspond, it is total connection ring 2 can be fixed on stator by multiple attachment screws 4 in this way
On 3, connection ring 2 and the fastness that field frame assembly 3 connects so far ensure that.
To realize that the another aspect of goal of the invention the utility model provides a kind of plastic packaging motor, including any of the above skill embodiment
The end cover mounting structure of described motor.
Above embodiments make the utility model have can make the connection between end cap and field frame assembly it is more stable, can
It leans on, avoids loosening therebetween, while also there is design rationally, the simple advantage of structure.
The above description is only the embodiments of the present invention, is not intended to limit the utility model, for this field
Technical staff for, various modifications and changes may be made to the present invention.Within the spirit and principle of the utility model,
Any modification, equivalent replacement, improvement and so on should be included within the scope of the claims of the utility model.
