Description

Technical Field

[0001] This utility model relates to the technical field of motors, and in particular to a motor mounting bracket. Background Technology

[0002] Electric motors, as an important power source, are widely used in many fields such as industrial automation, robotics, power tools, home appliances, and new energy vehicles.

[0003] Currently, commonly used motor mounting bracket structures mainly consist of a main housing and end caps fixed to both axial ends of the main housing. The main housing houses and supports the motor's core components, such as the stator and rotor. During operation, the motor generates heat. In existing technology, one of the main heat dissipation methods is to create several vents on the end caps of the mounting bracket. These vents are designed to allow hot air inside the motor to escape through convection, while simultaneously allowing cooler external air to enter, creating airflow to carry away heat.

[0004] However, the motor mounting bracket, which consists of the main body shell and end cover, is heavy, and the end cover cannot have large ventilation holes, resulting in low motor heat dissipation efficiency. Utility Model Content

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a motor mounting bracket that can reduce the overall weight of the motor and accelerate the dissipation of heat generated during motor operation.

[0006] According to an embodiment of the present invention, a mounting base for a motor is provided. The motor includes a rotor and a stator that rotate relative to each other. The mounting base includes a housing and two supports. The rotor and the stator are housed inside the housing. The two supports are respectively mounted at both ends of the housing. Each support includes a mounting ring, a support sleeve located inside the mounting ring, and a plurality of connecting ribs connecting the mounting ring and the support sleeve. The mounting ring is connected to an end of the housing. The rotor is provided with a rotating shaft, which is sleeved on the support sleeve. The plurality of connecting ribs are distributed circumferentially along the mounting ring, and a ventilation cavity is formed between two adjacent connecting ribs.

During motor operation, the heat generated inside the motor exchanges with the outside through a ventilation cavity. This ventilation cavity replaces the small vents in the traditional end cover, significantly increasing the airflow channel area, enhancing airflow efficiency, and reducing the internal temperature rise of the motor. This solves the problem of poor heat dissipation in existing motors. Furthermore, the heavy end cover is eliminated, and a lightweight support structure is adopted, greatly reducing the amount of metal used while maintaining structural rigidity, thus meeting the requirements for lightweight equipment.

[0010] According to an embodiment of the present invention, a motor mounting base is provided with a bearing inside the support sleeve, and the rotating shaft is installed inside the bearing.

[0011] According to an embodiment of the present invention, a motor mounting base has an abutment ring at one end of the support sleeve away from the housing. The abutment ring abuts against the end of the bearing, and the rotating shaft is accommodated inside the abutment ring.

[0012] According to an embodiment of the present invention, a motor mounting base further includes a dust filter cover, which extends circumferentially along the outer side of the connecting rib to cover the ventilation cavity.

[0013] According to an embodiment of the present invention, a motor mounting base is provided with a dust filter cover having a flange portion, which is connected to the mounting ring by bolts.

[0028] The following description, in conjunction with the accompanying drawings, describes a motor mounting bracket according to an embodiment of the present invention.

[0029] Reference Figure 1 The present invention aims to provide an embodiment of a motor mounting bracket.

[0030] This utility model discloses a motor mounting base. The motor includes a rotor 100 and a stator 110 that rotate relative to each other. The mounting base includes a housing 120 and two supports 130. The housing 120 houses the rotor 100 and the stator 110. The two supports 130 are respectively mounted at both ends of the housing 120. Each support 130 includes a mounting ring 140, a support sleeve 150 located inside the mounting ring 140, and a plurality of connecting ribs 160 connecting the mounting ring 140 and the support sleeve 150. The mounting ring 140 is connected to the end of the housing 120. The rotor 100 is provided with a rotating shaft 280, which is sleeved on the support sleeve 150. The plurality of connecting ribs 160 are distributed circumferentially along the mounting ring 140, and a ventilation cavity 170 is formed between two adjacent connecting ribs 160.

[0031] It is understood that this utility model, by setting up a housing 120 and two brackets 130, the bracket 130 is composed of a mounting ring 140, a support sleeve 150 and multiple connecting ribs 160. The mounting ring 140 is used to fix the bracket 130 to the end of the housing 120, and the support sleeve 150 can install the rotating shaft of the rotor 100. During the operation of the motor, the heat generated inside the motor can be exchanged with the outside through the ventilation cavity 170. The ventilation cavity 170 replaces the small air hole of the traditional end cover, which greatly increases the airflow channel area, significantly enhances the airflow efficiency, reduces the internal temperature rise of the motor, and solves the problem of poor heat dissipation of existing motors. In addition, the heavy end cover is eliminated and a lightweight bracket 130 structure is adopted, which greatly reduces the amount of metal used, while maintaining structural rigidity and meeting the requirements of lightweight equipment.

[0032] In some embodiments of this utility model, reference is made to Figure 2 and Figure 3 The connecting rib 160 has a first connecting section 180 and a second connecting section 190. The first connecting section 180 and the second connecting section 190 are connected to each other to form an L-shaped structure. The first connecting section 180 is connected to the end of the mounting ring 140 away from the housing 120, and the second connecting section 190 is connected to the end of the support sleeve 150 away from the mounting ring 140. It can be understood that the arrangement of the first connecting section 180 and the second connecting section 190 increases the cross-sectional area of ​​the ventilation cavity 170, which is conducive to efficient heat dissipation. In addition, the L-shaped structure of the connecting rib 160 is conducive to improving the torsional strength of the bracket 130.

[0033] In some embodiments of this utility model, a bearing 200 is provided inside the support sleeve 150, and a rotating shaft 280 is installed inside the bearing 200. It can be understood that by using the bearing 200 to rotatably connect with the rotating shaft 280, large friction is avoided between the rotating shaft 280 and the support sleeve 150, thereby reducing the risk of wear on the rotating shaft 280 and the support sleeve 150.

[0034] In some embodiments of this utility model, the support sleeve 150 has an abutment ring 210 at the end away from the housing 120. The abutment ring 210 abuts against the end of the bearing 200. The abutment ring 210 accommodates the rotating shaft 280. Therefore, the abutment ring 210 contacts the end face of the bearing 200 to prevent the bearing 200 from moving axially when the rotating shaft 280 rotates at high speed.

[0035] In some embodiments of this utility model, a dust filter 220 is also included. The dust filter 220 extends circumferentially along the outer side of the connecting rib 160 to cover the ventilation cavity 170. It is understood that the annular dust filter 220 blocks dust from entering the motor while maintaining high ventilation efficiency.

[0036] In some embodiments of this utility model, the dust filter cover 220 is provided with a flange 230, which is connected to the mounting ring 140 by bolts, thereby facilitating the installation and fixing of the dust filter cover 220.

[0037] In some embodiments of this utility model, the rotating shaft 280 is fitted with an impeller 270, which is located inside the mounting ring 140. It can be understood that the rotating shaft 280 drives the impeller 270 to rotate and generate negative pressure airflow, which forces external air to be drawn in from the ventilation cavity 170 and hot air to be discharged from the housing 120, thereby improving heat dissipation efficiency.

[0038] In some embodiments of this utility model, a connecting part 240 is provided at one end of the rotating shaft 280. The connecting part 240 is provided with an external thread. The connecting part 240 is connected to an external part through the external thread. It can be understood that the motor mounting base of this embodiment can be a mounting base for a floor fan motor. The rotating shaft 280 can be connected to an external fan blade. By tightening the external thread of the connecting part 240 with a nut, the fan blade can be fixed on the rotating shaft 280.

[0039] In some embodiments of this utility model, a reducer 250 is provided at the end of the rotating shaft 280 away from the connecting part 240. The reducer 250 is used to connect with the steering mechanism of the floor fan. Furthermore, a connecting shaft 260 is provided on the outer surface of the housing 120. The connecting shaft 260 is rotatably connected to the bracket 130 of the floor fan. It can be understood that the motor mounting base in this embodiment is a mounting base for the motor of the floor fan. The reducer 250 can reduce the speed of the rotating shaft 280 and increase the torque. The reducer 250 is connected to the steering mechanism of the floor fan, so that the motor rotates around the connecting shaft 260 as the center, causing the motor to change angle and meet the oscillation requirement of the floor fan.
