The support frame 100 is used for loading and supporting motor components such as stators and rotors, so that the motor can be smoothly assembled. Wherein, the brush 300 can directly penetrate the opening 155 and be installed in the mounting area 150, so as to achieve the relative installation effect between the brush 300 and the support frame 100, and the anti-off structure 310 is used for relatively positioning and fixing the brush 300 and the support frame 100. The brush 300 is directly installed in the mounting area 150 on the support frame 100 of the motor, so that the support shell used for installing the brush 300 in the prior art can be omitted, and the installation process between the brush 300 and the support frame 100 can be effectively simplified, thereby facilitating the assembly process of the motor and effectively improving the operation efficiency of the motor assembly.

[0032] In some embodiments, referring to Figure 2The outer side of the support frame 100 is provided with a support arm 130, and the mounting area 150 is arranged at the end of the support arm 130 away from the support frame 100, and the opening 155 is located at the end face of the support arm 130. The support arm 130 can effectively expand the extension range of the support frame 100, so that the support frame 100 can more smoothly load and support the motor components such as the stator, the rotor and the like. Moreover, the support arm 130 can also provide the brush 300 with a mounting position away from the support frame 100, so as to facilitate the installation of the brush 300 from the outer periphery of the support frame 100, and then facilitate the installation of the brush 300 into the mounting area 150.

[0033] Specifically, the support arm 130 extends from the middle of the support frame 100 towards the periphery of the support frame 100.

[0034] In some embodiments, referring to Figure 2 The support arm 130 and the brush 300 are both multiple and the same number, each brush 300 is installed one-to-one on the support arm 130, and each support arm 130 is distributed around the center of the support frame 100. Multiple support arms 130 can load and support other motor components such as the stator, the rotor and the like from multiple peripheral directions of the support frame 100, thereby effectively expanding the range of loading and supporting motor components by the support frame 100. Moreover, multiple support arms 130 can also provide each brush 300 with an orderly mounting position, so that multiple brushes 300 can be arranged in sequence on the outer periphery of the support frame 100, so as to facilitate the smooth and orderly electrical connection of the brush 300.

[0035] In some embodiments, referring to Figure 3 The anti-disengagement structure 310 includes a terminal 313 mounted on the support arm 130, and the terminal 313 is electrically connected with the brush 300; the terminal 313 covers at least part of the opening 155 and can block the brush 300 from disengaging from the mounting area 150 at the opening 155. The terminal 313 not only can electrically connect the brush 300 with the outside, but also can block the brush 300 at the opening 155, so that the brush 300 cannot disengage from the opening 155 by itself, thereby achieving the effect of positioning and fixing the brush 300 smoothly.

[0036] In some embodiments, referring to Figure 4 The anti-disengagement structure 310 includes a buckle 315 arranged on the terminal 313 and / or the support arm 130, and the terminal 313 and the support arm 130 are fixed to each other through the buckle 315. The buckle 315 not only can smoothly fix the terminal 313 and the support arm 130, but also has the advantages of simple installation and quick disassembly, so as to effectively facilitate the installation and fixing operation between the terminal 313 and the support arm 130, thereby improving the overall installation efficiency of the motor.

[0037] It is expected that the buckles 315 can be provided on the terminals 313 or the support arms 130, or both the terminals 313 and the support arms 130 are provided with the buckles 315 and are buckled by the two buckles 315. The specific embodiments are not unique, but can be adjusted according to the actual situation, which is not limited here.

[0038] In some embodiments, referring to Figure 4 , the side of the support arm 130 is provided with a passageway 325, the passageway 325 is connected with the opening 155, and part of the terminal 313 passes through the passageway 325 outside the support arm 130 and extends into the mounting area 150. The passageway 325 not only allows the terminal 313 to smoothly extend into the mounting area 150, but also positions the terminal 313 and the opening 155 relative to each other, so that the terminal 313 can be accurately mounted in the opening 155, and the disconnection of the brush 300 by the terminal 313 can be blocked.

[0039] In some embodiments, referring to Figure 3 , the buckle 315 is elastic and provided on the terminal 313, the width of the passageway 325 is less than the sum of the width of the terminal 313 and the width of the buckle 315, and the terminal 313 can drive the buckle 315 to pass through the opening 155. The elasticity of the buckle 315 allows it to contract and automatically rebound after passing through the passageway 325, so as to buckle and fix the passageway 325, thereby achieving the effect of buckling and fixing the terminal 313 and the support arm 130.

[0040] Specifically, the buckle 315 is an elastic spring provided on the terminal 313, which can contract under external force, so that the terminal 313 can drive the elastic spring to pass through the passageway 325, and then the buckle 315 automatically rebounds to achieve the effect of fixing the terminal 313 and the support arm 130 relative to each other.

[0041] In some embodiments, referring to Figure 3 , the passageway 325 is provided on the end side of the support arm 130, and the normal direction of the opening 155 is not parallel to the normal direction of the passageway 325. When the terminal 313 extends into the support arm 130 through the passageway 325, the orientation of the terminal 313 will be offset relative to the length direction of the support arm 130 due to the offset between the orientation of the passageway 325 and the opening, thereby effectively reducing the radial size of the motor as a whole. Moreover, since the passageway 325 is provided on the end side of the support arm 130, the length of the terminal 313 exposed outside relative to the support arm 130 can be reduced, thereby avoiding damage caused by accidental contact with the terminal 313.

[0042] In some embodiments, referring to Figure 4 A protective sleeve 320 is arranged in the mounting area 150, the brush 300 extends into and contacts the protective sleeve 320, and at least one of the protective sleeve 320 and the support frame 100 is an insulating member. The protective sleeve 320 can further surround and protect the brush 300, so as to avoid direct contact between the brush 300 and the support frame 100. Since at least one of the protective sleeve 320 and the support frame 100 is an insulating member, the brush 300 will be surrounded by the insulating member, thereby ensuring that the brush 300 is difficult to short circuit.

[0043] Specifically, the support frame 100 is made of insulating rubber or the like. Of course, the protective sleeve 320 can also be an insulating sleeve, and the specific implementation is not unique, but can be adjusted according to the actual situation, which is not limited here.

[0044] In some embodiments, referring to Figure 5 The support frame 100 is connected with a mounting disc 500, and the mounting disc 500 is provided with a flow guide structure 530 capable of guiding airflow to move close to or away from the center of the support frame 100. The mounting disc 500 is used for mounting the fan, so that the fan can be connected with the motor and heat dissipation of the motor. The flow guide structure 530 can ensure that the airflow blown by the fan can smoothly blow to the center of the motor, thereby effectively improving the heat dissipation effect of the motor.

[0045] Specifically, the support frame 100 and the mounting disc 500 are positioned and connected with each other through the rotating shaft of the motor, and the flow guide structure 530 includes a plurality of curved surfaces arranged on the end face of the mounting disc 500. The curved surfaces are curved and extended from the outer periphery of the mounting disc 500 towards the center of the mounting disc 500, and each curved surface is distributed equidistantly around the center of the mounting disc 500.

[0046] The utility model discloses a second aspect provides a kind of embodiment of motor, including above motor support. The support frame 100 is used to load and support motor components such as stator, rotor, so that the motor can be smoothly assembled. Among them, the brush 300 can directly pass through the open mouth 155 and be installed in the mounting area 150, so that the relative installation effect between the brush 300 and the support frame 100 is achieved, and the relative positioning and fixing between the brush 300 and the support frame 100 are carried out by the anti-dropping structure 310. The brush 300 is directly installed in the mounting area 150 on the support frame 100 of the motor, so that the support shell used for installing the brush 300 in the prior art can be omitted, and the installation process between the brush 300 and the support frame 100 can be effectively simplified, thereby facilitating the assembly process of the motor, and effectively improving the operation efficiency of motor assembly.

[0047] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, it is to be understood that the scope of protection includes each and every possible combination of the technical features.

[0048] The embodiments of the utility model are explained in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and within the knowledge range of ordinary skilled in the art, various changes can be made without departing from the purpose of the utility model.
