Description

Motor housing

Technical Field

The utility model relates to the technical field of electric machines, especially, relate to a motor housing.

Background

The Electric motor is widely applied to various industries as the most common Power source, for example, to an Electric Power Steering (EPS) system in an automobile Steering system. When a driver steers the steering wheel, the torque sensor detects the steering of the steering wheel and the magnitude of the torque, voltage signals are transmitted to the electronic control unit, and the electronic control unit sends instructions to the motor controller according to the voltage signals, so that the motor outputs steering power-assisted torque with corresponding magnitude and direction, and auxiliary power is generated. The EPS saves a power steering oil pump, a hose, hydraulic oil, a conveyor belt, a belt pulley and the like which are necessary for a hydraulic power steering system, thereby saving energy and protecting the environment.

In the existing structure, an EPS motor is fixed to an actuator of a steering system through a flange. The flange is of a full-circle structure, and materials at the central hole need to be punched off during production and manufacturing, so that the process is increased, and a large amount of materials are wasted. Further, if the actuator is changed in accordance with the hole site of flange mounting, the flange cannot be used, and the versatility is poor.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments, so that the technical solutions and the advantages thereof will be more clearly understood. It is to be understood that the drawings are provided for purposes of illustration and description only and are not intended as a definition of the limits of the invention, but the dimensions shown in the drawings are for convenience and are not to be taken as limiting the scale.

As shown in fig. 1 to 3, an embodiment of the motor housing of the present invention includes a housing 10 and a plurality of flanges 20 connected to the housing 10. The flange 20 is formed with a fixing hole 22 for assembling the motor with other mechanisms, such as an actuator of a steering system, etc.

The housing 10 has a cylindrical structure, and a space is formed inside the housing for mounting a rotor, a stator, and the like of the motor. The respective flanges 20 are disposed around the housing 10 and fixedly coupled to the sidewalls of the housing 10 by welding or the like. Each of the flanges 20 includes a body 24 and ears 26 extending from the body 24. The body 24 is of an arc segment structure and is attached to the side wall of the shell 10. In this embodiment, a ring groove 12 is formed on the side wall of the housing 10. The axial height of the body 24 of the flange 20 is the same as the axial height of the ring groove 12, and the inner diameter of the body 24 corresponds to the outer diameter of the housing 10 at the ring groove 12 thereof. Therefore, the body 24 can be just attached to the annular groove 12 on the side wall of the shell 10, and the annular groove 12 limits the body 24 in the radial direction and the axial direction, so that the flange 20 and the shell 10 can be conveniently welded. In other embodiments, the flange 20 may be welded directly to the sidewall of the housing 10, omitting the ring groove 12.

In this embodiment, there are two flanges 20, and the two flanges 20 are symmetrically disposed. Each of the flanges 20 has an arc length of about 1/4 circumferences, and the flanges 20 are circumferentially spaced apart by a distance of about 1/4 circumferences when the flanges 20 are assembled with the housing 10. The ear portion 26 extends radially outward from the axial side end of the body 24, and the fixing hole 22 is formed in the ear portion 26 and axially penetrates the ear portion 26. The fixing holes 22 are aligned with corresponding mounting holes of a mechanism, such as an actuator, and a fixing member, such as a screw, penetrates through the fixing holes 22 and the mounting holes to fixedly connect the motor to the actuator.

In the above embodiment, the two flanges 20 are symmetrically arranged, and it should be understood that the two flanges 20 may have different configurations according to the positions of the assembly holes of the corresponding mechanisms. In the embodiment shown in fig. 4, the two flanges 20 are arranged asymmetrically, and the angle or distance between the two flanges 20 is determined according to the positions of the assembly holes, so as to ensure that the fixing holes 22 of each flange 20 are aligned with the assembly holes of the corresponding mechanism one by one.

In the two embodiments shown in fig. 3 and 4, there are two flanges 20, and there are two fixing holes 22, respectively, which are connected with the mechanism of the two assembling holes. It should be understood that the number and length of the flanges 20 of the motor housing of the present invention can be adjusted as required. In the embodiment shown in fig. 5, there are three flanges 20, and the three flanges 20 are symmetrically arranged, and each flange has an arc length not less than 1/6 circumferential lengths. Each flange 20 is formed with a fastening hole 22 to be correspondingly coupled with a mechanism having three symmetrically arranged assembly holes. As shown in fig. 6, the three flanges 20 may be asymmetrically arranged, and may be correspondingly provided with a mechanism having three asymmetrically arranged mounting holes. In summary, the number, relative position, etc. of the flanges 20 of the motor housing of the present invention are adjusted according to practical applications, and are not limited to the above embodiments.

The utility model discloses motor housing's flange 20 is the circular arc section structure, has consequently lacked the technology of dashing the centre bore department material when the production preparation, has not only reduced the processing procedure, and more importantly can increase substantially the utilization ratio of material. Moreover, the flanges 20 of the motor housing can be changed correspondingly according to the specific application environment, and when the positions or the number of the assembly holes are changed, only the number of the flanges 20 needs to be changed correspondingly or the relative positions of the flanges 20 need to be adjusted, mold opening is not needed again, and the universal matching performance is good.

The above description is only a preferred embodiment of the present invention, the protection scope of the present invention is not limited to the above listed embodiments, any person skilled in the art can obviously obtain simple changes or equivalent substitutions of the technical solutions within the technical scope of the present invention.
