Specific embodiment

In conjunction with referring to figs. 1 to 5, embodiment according to the present utility model, electric motor end cap includes lid 1, lid 1 First end face is provided with backstop bulge loop 2, and backstop bulge loop 2 is provided with annular caulking groove 3 far from one end of lid 1.

Casing 10 can be embedded into the annular caulking groove 3 of backstop bulge loop 2 when being cooperated with casing 10 by the electric motor end cap Interior, to form detour channel by the two side walls of annular caulking groove 3, when assembly, which is equivalent to, is embedded into electric motor end cap for casing 10 It is interior, the bonded area between motor and end cap is increased on the basis of existing structure, has completely cut off connection inside motor and external Be channel, greatly reinforced the sealing effect of motor, improve the degree of protection of motor, indirectly improve motor use scope and Service life.

Further, since improving the waterproof effect of motor, therefore it is able to solve long-term rain spraying environment and will cause in motor The problem of portion intakes improves motor quality, reduces failure after sale, while product competitiveness in the market can be improved.

Backstop bulge loop 2 includes internal ring wall 4 and external annulus 5, and annular caulking groove 3 is formed between internal ring wall 4 and external annulus 5.At this In embodiment, backstop bulge loop 2 is split type structure, can facilitate and improve on the basis of existing structure, i.e., at existing end The peripheral side of the seam allowance (i.e. internal ring wall 4) of lid increases annular sidewall structure (i.e. external annulus 5) by modes such as bondings, thus in electricity Increase a vertically integrated face between generator terminal lid and casing 10, workload can be reduced, reduces improvement cost.

Certainly, internal ring wall 4 and external annulus 5 can also be integrally formed with lid 1 simultaneously.

Internal ring wall 4 and external annulus 5 can be commonly connected on lid 1, and internal ring wall 4 and the setting of the interval of external annulus 5, can also It is structure as a whole with internal ring wall 4 and external annulus 5, so that backstop bulge loop 2 is integrally formed formula structure, can more easily be guaranteed interior Concentricity between ring wall 4 and external annulus 5 guarantees the uniformity of fit clearance between electric motor end cap and casing 10, guarantees sealing Effect.

Connecting hole 6 is provided on the lid 1 of the inner circumferential side of backstop bulge loop 2, connecting hole 6 and the annular interval of caulking groove 3 are arranged.By It needs to be attached with the stator of motor in connecting hole 6, and stator is that setting is arranged in casing 10, therefore by connecting hole 6 In the inner circumferential side of annular caulking groove 3, since casing 10 is embedded in annular caulking groove 3, it is possible to prevente effectively from casing 10 is right The connection of connection bolt causes to interfere, and guarantees being fixedly connected between stator and motor housing.

Connecting hole 6 in axial direction runs through the inner sidewall of backstop bulge loop 2, and it is convex that the part hole wall of the connecting hole 6 is located at backstop It, can be while guaranteeing has enough radial spacings between connecting hole 6 and annular caulking groove 3, so that connection on the inner sidewall of ring 2 Hole 6 is arranged towards the periphery of stator as far as possible, and more convenient installation for realizing stator is fixed, and structure utilization is more abundant.

Preferably, convex block 7 is additionally provided in first end face, convex block 7 is located at the ipsilateral of first end face with backstop bulge loop 2, even Hole 6 is connect to be arranged on convex block 7.Convex block 7 can increase wall thickness of the lid 1 at the position of setting connecting hole 6, increase electric motor end cap Structural strength, reduce the possibility that deforms of electric motor end cap, improve the stability and reliability of electric machine structure.

Preferably, the opening of annular caulking groove 3 is provided with guiding surface, can be embedding at annular caulking groove 3 to casing 10 Enter to play effective guiding function, it is more convenient that casing 10 is assembled in annular caulking groove 3, facilitate and realizes electric motor end cap and casing Assembly between 10 is fixed, and assembly efficiency is improved.

Preferably, reinforcing rib 8, circumferential direction uniform cloth of multiple reinforcing ribs 8 along lid 1 have been disposed radially in first end face If the structural strength of electric motor end cap can be further strengthened by reinforcing rib 8, it is strong to improve structure of the electric motor end cap at axis hole Degree avoids electric motor end cap from deforming in axis hole location recurring structure.The reinforcing rib for being preferably located at same radial direction can be Multiple, multiple reinforcing ribs can be arranged along the spaced radial of lid 1, while playing effective booster action, enable to add The structure setting of strengthening tendons is more reasonable.

By above-mentioned end cover structure, an annular sidewall structure, phase need to be only increased newly at the seam allowance outer circle of electric motor end cap When increasing a vertically integrated face newly between electric motor end cap and casing 10, a detour channel is formed with original structure, is increased The contact area of casing 10 and electric motor end cap has completely cut off contact channel inside motor and external, has greatly reinforced motor Sealing effect improves the degree of protection of motor.This structure processing casting process is simple, practical, does not influence to install, and do not have There is the fixation outer circle for destroying motor, does not influence original assemble sequence of motor, this sealing structure can be used in degree of protection On the motor of higher roll bending casing class.

In conjunction with referring to fig. 4 and shown in Fig. 5, embodiment according to the present utility model, motor housing includes first end cover 9, machine Shell 10 and second end cover 11, the first end cover 9 and/or second end cover 11 are above-mentioned electric motor end cap, and casing 10 is embedded in motor In the annular caulking groove 3 of end cap.

Embodiment according to the present utility model, motor include motor housing, which is above-mentioned motor housing.

Those skilled in the art will readily recognize that above-mentioned each advantageous manner can be free under the premise of not conflicting Ground combination, superposition.

The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the utility model within novel spirit and principle Within the scope of shield.Above are merely preferred embodiments of the utility model, it is noted that for the ordinary skill of the art For personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these improvement It also should be regarded as the protection scope of the utility model with modification.
