[0033] The following will introduce in detail the specific structure of a motor provided by an embodiment of the present utility model and the corresponding technical effects brought thereby with reference to the patent drawings.

[0034] Please refer to Figures 1 - 4 , a motor provided by an embodiment of the present utility model includes an insulating frame 200, an external wire 902, and an enameled wire 901. An installation unit 300 is provided on the installation surface 211 of the insulating frame 200. The installation unit 300 forms an installation groove 370 on the insulating frame 200. The enameled wire 901 is connected to the external wire 902 to form a wire harness 900 and can be snap-fitted and installed in the installation groove 370.

[0035] It should be noted that the external wire can be understood as three phase wires or a neutral wire. That is, each phase wire can be connected to an enameled wire 901 to form a wire harness 900.

[0036] It can be understood that a phase wire in the external wire can be connected to an enameled wire 901 to form a wire harness 900 and can be connected and snap-fitted and installed together in the installation groove 370. That is, the snap-fitting installation of the external wire and the enameled wire 901 is completed through the installation groove 370, which can avoid the occurrence of a short circuit caused by the contact between the phase wire and the iron core.

[0037] The motor further includes pressing members 380 and cooperating members 390 disposed on both sides of the mounting unit 300. When the pressing members 380 are connected to the cooperating members 390, the pressing members 380 press the side of the mounting unit 300 away from the mounting surface 211 to press the wire harness 900 into the mounting groove 370.

[0038] Among them, the mounting groove 370 includes a first sub-groove 371, a second sub-groove 372, and a third sub-groove 373 that are sequentially arranged at an angle and communicate with each other. The wire harness 900 is sequentially snapped into the first sub-groove 371, the second sub-groove 372, and the third sub-groove 373. When the pressing members 380 are connected to the cooperating members 390, the pressing members 380 press at least one of the first sub-groove 371, the second sub-groove 372, and the third sub-groove 373. It can be understood that the pressing members 380 can press the side of the wire harness 900 away from the mounting surface 211 to stably accommodate the wire harness 900 in the mounting groove 370.

[0039] It should be noted that since the mounting groove 370 includes a first sub-groove 371, a second sub-groove 372, and a third sub-groove 373 that are sequentially arranged at an angle and communicate with each other, when the wire harness 900 is snapped in, it will sequentially extend along the extending direction of the first sub-groove 371, the extending direction of the second sub-groove 372, and the extending direction of the third sub-groove 373, thereby ensuring that the wire harness 900 is stably snapped into the mounting groove 370.

[0040] In this embodiment, when the pressing members 380 are connected to the cooperating members 390, the pressing members 380 press the sides of the first sub-groove 371 and the third sub-groove 373 away from the mounting surface 211.

[0041] Specifically, in this embodiment, the mounting unit 300 includes a first side wall 310, a second side wall 320, and a third side wall 330 that are sequentially arranged at intervals. A first sub-groove 371 is defined between the first side wall 310 and the second side wall 320, a third sub-groove 373 is defined between the second side wall 320 and the third side wall 330, and the second sub-groove 372 is formed between the first side wall 310, the second side wall 320, and the third side wall 330.

[0042] Furthermore, in this embodiment, the mounting unit 300 further includes a fourth side wall 340. Both ends of the fourth side wall 340 are respectively connected to the second side wall 320 and the third side wall 330. Through the arrangement of the fourth side wall 340, the wire harness 900 located in the third sub-groove 373 is not easily disengaged from the third sub-groove 373.

[0043] It should be noted that the first side wall 310, the second side wall 320, the third side wall 330, and the fourth side wall 340 in this embodiment are all structures protruding from the mounting surface 211.

[0044] Specifically, the insulating bracket 200 includes a connecting surrounding plate 220 and a bottom plate 210. The bottom plate 210 has an installation surface 211. The first side wall 310, the second side wall 320, the third side wall 330 and the fourth side wall 340 are all convexly provided on the bottom plate 210. One end of the first side wall 310 is connected to the surrounding plate 220, and one end of the second side wall 320 far from the fourth side wall 340 is connected to the surrounding plate 220. One end of the third side wall 330 far from the fourth side wall 340 is connected to the surrounding plate 220.

[0045] It can be seen therefrom that the assembly line snapped into the installation groove 370 will be restricted by the surrounding plate 220. Specifically, the wire harness 900 located in the third sub-groove 373 can be restricted by the fourth side wall 340 and the surrounding plate 220 to ensure that the assembly line is stably installed in the installation groove 370.

[0046] Wherein, a second sub-groove 372 communicating with the first sub-groove 371 and the third sub-groove 373 is provided on the second side wall 320. The second sub-groove 372 is located between the surrounding plate 220 and the fourth side wall 340, and the second sub-groove 372 penetrates through the second side wall 320 along the thickness direction of the second side wall 320.

[0047] In order to further improve the stability of the installation of the wire harness 900, at least one of the first side wall 310, the second side wall 320 and the third side wall 330 is convexly provided with a limiting portion 350, and the limiting portion 350 is used for clamping the wire harness 900 with an adjacent side wall or an adjacent limiting portion 350.

[0048] Specifically, in this embodiment, a limiting portion 350 is convexly provided on one side of the first side wall 310 close to the second side wall 320, and a limiting portion 350 is also convexly provided on one side of the second side wall 320 close to the first side wall 310. That is to say, in the first sub-groove 371, the wire harness 900 is clamped by two opposite limiting portions 350 to ensure the stability of the assembly of the wire harness 900.

[0049] In the third sub-groove 373, a limiting portion 350 is convexly provided on one side of the second side wall 320 close to the third side wall 330, and a limiting portion 350 is also convexly provided on one side of the third side wall 330 close to the second side wall 320. Similarly, in the third sub-groove 373, the wire harness 900 can also be clamped by two opposite limiting portions 350 to ensure the stability of the assembly of the wire harness 900.

[0050] Of course, in some other embodiments, within the first sub-slot 371, only the side of the first sidewall 310 close to the second sidewall 320 may be provided with a limiting portion 350 protruding therefrom, or only the side of the second sidewall 320 close to the first sidewall 310 may be provided with a limiting portion 350 protruding therefrom. Within the second sub-slot 372, only the side of the second sidewall 320 close to the third sidewall 330 may be provided with a limiting portion 350 protruding therefrom, or only the side of the third sidewall 330 close to the second sidewall 320 may be provided with a limiting portion 350 protruding therefrom.

[0051] At least two of the first sidewall 310, the second sidewall 320, and the third sidewall 330 are provided with wire pressing grooves 360 recessed towards the mounting surface 211 on the side away from the mounting surface 211. When the pressing member 380 presses the side of the mounting unit 300 away from the mounting surface 211, the pressing member 380 is received within the wire pressing groove 360. That is to say, through the setting of the wire pressing groove 360, the distance between the pressing member 380 and the mounting surface 211 can be made smaller when pressing the wire harness 900, thereby pressing the wire harness 900 more tightly against the mounting surface 211. And the wire pressing groove 360 can also provide a receiving space for the pressing member 380, enabling the pressing member 380 to be stably arranged within the wire pressing groove 360, so as to ensure that the pressing member 380 stably presses the wire harness 900.

[0052] Specifically, in this embodiment, the first sidewall 310, the second sidewall 320, and the third sidewall 330 are all provided with wire pressing grooves 360 on the side away from the mounting surface 211.

[0053] In this embodiment, in order to enable the pressing member 380 to more firmly mount the wire harness 900 within the mounting groove 370. The extending direction of the wire pressing groove 360 in this embodiment passes through the limiting portion 350. That is to say, the wire pressing groove 360 on the first sidewall 310 passes through the limiting portion 350 protruding from the first sidewall 310, the wire pressing groove 360 on the second sidewall 320 passes through the limiting portion 350 protruding from the second sidewall 320, and the wire pressing groove 360 on the third sidewall 330 passes through the limiting portion 350 protruding from the third sidewall 330. In other words, the bottom wall of the wire pressing groove 360 on the first sidewall 310 is the top wall of the limiting portion 350 protruding from the first sidewall 310, the bottom wall of the wire pressing groove 360 on the second sidewall 320 is the top wall of the limiting portion 350 protruding from the second sidewall 320, and the bottom wall of the wire pressing groove 360 on the third sidewall 330 is the top wall of the limiting portion 350 protruding from the third sidewall 330.

[0054] Specifically, both the pressing member 380 and the mating member 390 are disposed on the bottom plate 210. After the pressing member 380 is connected to the mating member 390, the pressing member 380 presses the side of the mounting unit 300 away from the bottom plate 210. That is to say, after the wire harness 900 is snap-fitted into the mounting groove 370, after the pressing member 380 is connected to the mating member 390, the wire harness 900 can be pressed into the mounting groove 370 by the pressing member 380, preventing the wire harness 900 in the mounting groove 370 from moving in the direction away from the bottom plate 210 and ensuring the stable installation of the wire harness 900 in the mounting groove 370.

[0055] Specifically, in this embodiment, the pressing member 380 is located on the side of the third side wall 330 away from the second side wall 320, and the mating member 390 is located on the side of the first side wall 310 away from the pressing member 380.

[0056] Please refer to Figure 4 , the wire harness 900 sequentially passes through the first sub-groove 371, the second sub-groove 372, and the third sub-groove 373. It should be noted that Figure 4 the wire harness 900 in Figure 4 is only for the schematic illustration of being snapped into the mounting groove 370, and the wire diameter dimension of the wire harness 900 in

[0057] One end of the pressing member 380 away from the insulating bracket 200 is provided with a first mating portion 381, and one end of the mating member 390 away from the insulating bracket 200 is provided with a second mating portion 391 for detachably connecting with the first mating portion 381. The pressing member 380 can undergo flexible deformation. Specifically, one end of the pressing member 380 away from the bottom plate 210 is provided with a first mating portion 381, and one end of the mating member 390 away from the bottom plate 210 is provided with a second mating portion 391. During the process of connecting the pressing member 380 to the second mating portion 391 of the mating member 390 through the first mating portion 381, the pressing member 380 can deform, and then press the side of the mounting unit 300 away from the bottom plate 210, realizing the pressing on the top of the mounting groove 370 and preventing the wire harness 900 snap-fitted in the mounting groove 370 from moving in the direction away from the bottom plate 210.

[0058] In some alternative embodiments, to facilitate the deformation of the pressing member 380 during its movement towards the mating member 390 for connection, the thickness dimension of the pressing member 380 gradually decreases in the direction closer to the insulating bracket 200. That is to say, the thickness dimension of the pressing member 380 gradually decreases in the direction closer to the bottom plate 210. Since the thickness dimension in the direction closer to the bottom plate 210 is smaller, it is convenient for the pressing member 380 to deform relative to the bottom plate 210.

[0059] It can be understood that in some other embodiments, a connecting block may also protrude from the bottom plate 210. The connecting block is hinged to the pressing member 380 to enable the pressing member 380 to rotate relative to the bottom plate 210. And after the first engaging portion 381 of the pressing member 380 is connected to the first engaging portion 381 of the engaging member 390, the pressing member 380 can be pressed on the side of the mounting unit 300 away from the bottom plate 210.

[0060] In this embodiment, the first engaging portion 381 is snap-connected to the second engaging portion 391, and the first engaging portion 381 and the second engaging portion 391 are snap-fasteners that snap-connect to each other. Of course, in some other embodiments, the first engaging portion 381 and the second engaging portion 391 may also be other detachable connection methods. For example, the first engaging portion 381 and the second engaging portion 391 can be connected by a fastener, and the fastener can be a plug or a threaded fastener. When the fastener is a plug, the first engaging portion 381 and the second engaging portion 391 have plug holes through which the common plug penetrates. When the fastener is a threaded fastener, one of the first engaging portion 381 and the second engaging portion 391 has a threaded hole, and the other has a through hole.

[0061] There are multiple mounting units 300, and the multiple mounting units 300 are arranged at intervals along the circumferential direction of the bottom plate 210. Specifically, in this embodiment, the number of the mounting units 300 is four. It can be understood that the external wiring 902 includes three phase lines and one neutral line. Each of the three phase lines and one neutral line is respectively connected to an enameled wire 901 to form four wire bundles 900, and the four wire bundles 900 can be respectively installed and fixed by the four mounting units 300.

[0062] In some alternative embodiments, the motor further includes an insulating sleeve (not shown in the figure). The insulating sleeve is sleeved on the wire bundle 900 and can be snap-connected and installed in the installation groove 370.

[0063] To facilitate the entry of the external wiring 902 onto the insulating frame 200, one end of the motor shaft 100 is provided with a shaft hole 101 and a side hole 102 communicating with the shaft hole 101. The axis of the shaft hole 101 is parallel to the axis direction of the motor shaft 100. The external wiring 902 can sequentially pass through the shaft hole 101 and the side hole 102 to enter the insulating frame 200 and be connected to the enameled wire 901.

[0064] Of course, the motor of this embodiment further includes structures such as end covers 800, stator assemblies, rotors, bearings, and housings 500. Among them, the end covers and the housings are sleeved on the motor shaft 100, the housing covers the end cover, and the stator assembly, the rotor, and the insulating frame 200 are all located inside the housing and the end cover. The stator assembly has a stator core, and the three-phase winding is usually wound by enameled wires 901. In this embodiment, the winding is located outside the surrounding plate 220 of the insulating frame 200, and the winding is wound around the stator core to form three groups, which are connected to the L1, L2, and L3 phase lines of the three-phase power supply. The magnetic field generated by the winding rotates with the change of the current phase, which is the root cause of the motor generating power. Since the above structure is a conventional setting in this field, the specific structure thereof will not be elaborated herein.

[0065] In summary, a motor provided by an embodiment of the present invention includes an insulating frame 200, an external connection wire 902, and enameled wires 901. An installation unit 300 is provided on the installation surface 211 of the insulating frame 200. The installation unit 300 is disposed on the insulating frame 200 and forms an installation groove 370 on the insulating frame 200. The enameled wires 901 are connected to the external connection wire 902 to form a wire harness 900 and can be snap-fitted and installed in the installation groove 370. The snap-fitting installation of the external wire and the enameled wires 901 is completed through the installation groove 370, which can avoid the occurrence of a short-circuit situation caused by the phase line contacting the iron core.

[0066] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
