Summary of the invention

High-efficient electricity low technical problem to be solved by the utility model is to provide a kind of labor intensity and easy for installation Machine support assembly.

The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of electric machine support assembly includes motor branch Frame, the electric machine support have abutment wall, have location hole in the abutment wall, and the inner wall of the abutment wall is opposite with motor shaft core line, should The outside wall surface of abutment wall is away from each other with motor shaft core line；Brush-box, the brush-box include the first rectangular cylinder, which injects The location hole is formed to inner end, cooperation section and outward, this is placed within the inner wall to inner end and outward and outside wall surface In addition；Copper carbon set；The brush-box further includes integrally formed positioning shoulder block and the first Elastic buckle, which is placed in first On the stack shell of rectangular cylinder, which offsets with the outside wall surface, which is placed in the end to inner end, should First Elastic buckle may pass through the location hole and offset with the inner wall, which is adapted with the location hole.

The utility model has the advantages that due to following technical characteristic: brush-box is directly inserted into location hole in above-mentioned technical proposal, when When positioning shoulder block is bonded with the outside wall surface of abutment wall, offset simultaneously with inner wall to the first buckle of inner end end, so that positioning Shoulder block and the first buckle have clamped abutment wall simultaneously, reach fixed effect, convenient and efficient, are not necessarily to proficiency of workers and attention Power is concentrated to improve yield, and convenient for realizing automation in the production line, it is low and easy for installation high-efficient to solve labor intensity Problem.The forming of brush-box integrated injection molding, reduces cost of parts.

As a concrete scheme to above-mentioned technical proposal, first Elastic buckle includes being respectively placed in the rectangle The first elastic fin on two planes of symmetry of cylinder or so, the head of first elastic fin are fixed in the end to inner end Portion, the tail portion of first elastic fin are directed toward the inner wall and offset therewith.This concrete scheme makes the first elastic fin, determines Position shoulder block and the forming of the first rectangular cylinder integrated injection molding more meet the demoulding requirement of moulding, and the locating effect in abutment wall is more It is good.

As further improvement to above-mentioned technical proposal, the longitudinal section of the first elastic fin is domed.The improvement makes The performance of positioning is opened more preferably when collapsing and leave location hole when one elastic fin passes through location hole.

As a concrete scheme to above-mentioned technical proposal, copper carbon set is the second rectangle that there is the second Elastic buckle in one end Cylinder, second Elastic buckle can from it is described outward pass through first rectangular cylinder in, be placed in it is described to outside inner end simultaneously It offsets with described to the end of inner end, the inside of the outer cross of second rectangular cylinder and first rectangular cylinder is horizontal Section is adapted.

As further improvement to above-mentioned technical proposal, the second Elastic buckle includes being respectively placed in second rectangular cylinder The second elastic fin above and below body on two planes of symmetry, the head of second elastic fin is fixed in second rectangular cylinder End, the tail portion of second elastic fin is directed toward the end to inner end and offsets therewith.

Detailed description of the invention

Fig. 2 is the front sectional view of the utility model；

Fig. 3 is the bottom view of the utility model.

Specific embodiment

The present invention will be further described with reference to the accompanying drawings and examples.

Referring to Fig. 1, a kind of electric machine support assembly of the present embodiment, including electric machine support 1, brush-box 2, copper carbon set 3.Motor Bracket 1 has abutment wall 11, there is location hole 111 in abutment wall 11, and the inner wall 112 of abutment wall is opposite with motor shaft core line, bearing The outside wall surface 113 of wall is away from each other with motor shaft core line；Brush-box 2 includes the first rectangular cylinder, and brush-box 2 injects location hole 111 It is formed to inner end 21, cooperation section 22 and outward 23, is placed within inner wall 112 to inner end 21 and outward 23 and outer wall Other than face 113；First Elastic buckle 211 includes the first resilient wing being respectively placed on first rectangular cylinder or so, two planes of symmetry Piece 2111, the head of the first elastic fin 2111 are fixed in the end to inner end 21, have positioning shoulder block on the stack shell of brush-box 2 24, there is the first Elastic buckle 211 to inner end 21, copper carbon set 3 is the second rectangular cylinder that there is the second Elastic buckle 31 in one end, second Elastic buckle 31 includes the second elastic fin 311 being respectively placed on two planes of symmetry of the second rectangular cylinder or more, the second elasticity The head of fin 311 is fixed in the end of the second rectangular cylinder.Fig. 2 is participated in, positioning shoulder block 24 offsets with outside wall surface 113；Cooperation Section 22 is adapted with location hole 111.Second Elastic buckle 31 can from outward 23 pass through the first rectangular cylinder in, be placed in inner end It offsets outside 21 and with to the end of inner end 21, the internal cross section of the outer cross of the second rectangular cylinder and the first rectangular cylinder It is adapted.The end at the inwardly-directed end 21 in the tail portion of the second elastic fin 311 simultaneously offsets therewith.
