Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-3, an electric machine end cover assembly structure 10 includes: a lead assembly 11, a brush holder assembly 12 and a mounting end cap 13.

As a specific structure, the lead assembly 11 includes: two leads 111 and four brushes 112. Two of the four brushes 112 are electrically connected to one of the two leads 111 by wires 113. The other two of the four brushes 112 are electrically connected to the other of the two leads 111 by wires 113. The brush holder assembly 12 is mounted to the mounting end cap 13 with a receiving space formed therebetween the mounting end cap 13. The receiving space is used to receive the lead 111 and the wire 113 so as to keep the wiring of the mounting structure neat. The brush holder assembly 12 includes: a base plate 121 and four brush holders 125. The four brush holders 125 are used to mount the four brushes 112, respectively. Four brush holders 125 are fixed to the base plate 121 on a side of the base plate 121 remote from the mounting end cap 13. The base plate 121 is formed with four card holes 122. The card hole 122 is used for the lead 111 and the lead 113 to pass through so as to arrange and receive the lead 111 and the lead 113 into the accommodating space.

Specifically, one end of each of the two leads 111 passes through two adjacent card holes 122 and extends into the accommodating space to be stored in the accommodating space. Since the four brushes 112 are electrically connected to the lead 111 through the wires 113, the wires 113 are drawn out of the accommodating space again from the accommodating space by passing through the card holes 122. At this time, one end of the wire 113 is electrically connected to the lead 111, and the other end is connected to the brush 112 at the side of the base plate 121 where the brush holder 125 is disposed. Finally, the brush 112 is inserted into the brush holder 125 to complete the assembly.

Specifically, the plurality of brushes 112 of the motor end cover assembly structure 10 are directly connected to the two leads 111 through the wires 113 respectively, and are connected to the bottom plate 121 as a whole with the two leads 111, so that the mounting structure is simple, and the production cost is low. Meanwhile, the bottom plate 121 is provided with a plurality of clamping holes 122, so that the lead wires 111 and the lead wires 113 can be arranged on one side of the bottom plate 121 far away from the brush holder 125 by passing through the clamping holes 122, i.e. the lead wires 111 and the lead wires 113 are arranged and contained in the containing space. Such a structure ensures that the wiring on the side of the bottom plate 121 where the brush holder 125 is installed is simple, the circuit is neat, and the main circuit can be protected through the bottom plate 121, thereby preventing the lead 111 and the lead 113 from being damaged due to external factors.

As a specific embodiment, the card hole 122 is formed with a guide groove 123 and a card slot 124. The guide grooves 123 serve to guide the lead wires 111 and the lead wires 113 into the card slot 124, thereby fixing the lead wires 111 and the lead wires 113 in the card slot 124. Specifically, one end of the guide groove 123 is open and the other end is communicated to the card slot 124.

Further, the card slot 124 is a circular card slot 124. The width of the guide groove 123 is equal to or less than the radius of the card slot 124. This prevents the lead 111 and the wire 113 from coming out of the card slot 124.

As a specific embodiment, four brush holders 125 are uniformly distributed along the circumferential direction of the base plate 121.

Further, the brush holder 125 is a square sleeve structure. Such a structure is similar to the outer shape of the brush 112, and the brush 112 can be prevented from being reversely rotated in the brush holder 125.

As a specific embodiment, the mounting end cap 13 is formed with a through slot 131. The through groove 131 is used for the lead 111 to extend into the accommodating space. The lead 111 passes through the through slot 131 and is at least partially secured within the through slot 131. This ensures the mounting accuracy of the mounting end cap 13, and prevents the lead 111 from being damaged due to being pressed by the mounting end cap 13 when mounting.

As a specific embodiment, two of the four brushes 112 are connected to one end and the wire body of one of the two lead wires 111, respectively. The other two of the four brushes 112 are connected to one end of the other of the two lead wires 111 and the wire body.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by adopting equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
