Description
Technical Field
[0001] This application relates to the field of motors, and more particularly, to a high-power control drive motor. Background Art
[0002] A high-power control drive motor refers to an electric motor that can operate at a relatively high power level and is used to control mechanical motion. Such motors can usually provide high torque and large output power, and are suitable for various industrial applications, such as machining, mining equipment, wind power generation, electric vehicles, and other occasions that require high-performance drives.
[0003] In existing high-power control drive motors, a cooling fan is generally installed on the rear end shaft. However, during long-term use, a large amount of dust or impurities will inevitably adhere to the outside of the cooling fan. The presence of dust will obstruct the airflow, reduce the heat dissipation effect of the cooling fan, cause the motor temperature to rise, and thus affect the operation of the motor. Therefore, it is necessary to regularly disassemble the cooling fan to clean the dust or impurities adhering to it. However, in the prior art, when disassembling the cooling fan, a disassembly tool is required to pry the cooling fan off the motor shaft. Since the rear end shaft of the motor is in a movable state during disassembly, the rear end shaft of the motor will rotate due to the frictional force between the fan and the shaft or other external forces during disassembly, which may cause accidental injury or damage between the cooling fan and the motor shaft during disassembly. Therefore, a high-power control drive motor is needed to assist in solving this problem. Summary of the Utility Model
[0004] The content part of this application is used to briefly introduce concepts, which will be described in detail in the following detailed implementation part. The content part of this application is not intended to identify the key features or essential features of the claimed technical solution, nor is it intended to limit the scope of the claimed technical solution.
[0005] To solve the technical problems mentioned in the above background art part, some embodiments of this application provide a high-power control drive motor, including a motor body. The rear end of the motor body is fixed with a fan cover through a plurality of first bolts. A cooling fan is sleeved on the rear end shaft of the motor body. A stopping member is installed at the rear end of the motor body and is also connected to the rear end shaft. The stopping member is used to stop the rear end shaft. It also includes a transmission member, and the transmission member is used to cancel the stop of the rear end shaft. The transmission member is installed on the inner wall of the fan cover and is connected to the stopping member.
[0006] Further, the stopping member includes an annular plate fixed to the rear end of the motor body through a plurality of second bolts. A lightweight groove is provided on the annular plate between every two adjacent second bolts, and the lightweight grooves are all in an arc-shaped structure.
[0007] Furthermore, between every two adjacent lightweight slots, there is a U-shaped guide rod movably inserted into the front side of the annular plate. On each U-shaped guide rod, the cross-section of the end far from the rear end shaft is in a convex structure, and an arc-shaped tooth plate is fixedly connected to the other end. On the front side of the annular plate, there are two moving channels respectively matching with each U-shaped guide rod, and the two moving channels are symmetrically distributed about the central axis of the same U-shaped guide rod.
[0008] Furthermore, there is a gear fixedly connected to the outside of the rear end shaft among the multiple arc-shaped tooth plates, and the arc-shaped tooth plates are used to clamp and fix the gear.
[0009] Furthermore, on the arc-shaped surfaces of the multiple arc-shaped tooth plates facing away from the gear, they are all connected to the inner wall of the annular plate through elastic pieces, and the vertical cross-sections of the elastic pieces are all in a hourglass shape structure.
[0010] Furthermore, the transmission member includes a plurality of square-shaped plates arranged in a circular array on the inner wall of the fan cover. Each square-shaped plate is fixed to the inner wall of the fan cover through a third bolt. One end of each square-shaped plate facing the rear end shaft is fixedly connected with a transmission block. The inside of each transmission block is in a hollow structure, and the number of the transmission blocks is equal to the number of the U-shaped guide rods.
[0011] Furthermore, at one end of each transmission block facing the rear end of the motor body, a fourth inclined surface is provided, and fifth inclined surfaces are provided on both sides of each fourth inclined surface.
[0012] Furthermore, on each U-shaped guide rod, a first inclined surface matching with the fourth inclined surface is provided on the inner wall of the side facing the outside of the annular plate. Second inclined surfaces are provided on both sides of each first inclined surface on the inner wall of the U-shaped guide rod, and the second inclined surfaces are respectively matched with the fifth inclined surfaces on the corresponding side. Third inclined surfaces are also provided on the outside of the annular plate between every two second inclined surfaces.
[0013] The beneficial effect of this application is as follows: A high-power control drive motor is provided. By setting the stop member, after the fan cover is disassembled, the fourth inclined surfaces on the transmission blocks can respectively cancel the extrusion of the first inclined surfaces. Even if each U-shaped guide rod drives the connected arc-shaped tooth plates to move towards the gear direction under the rebounding action of the elastic piece, so as to realize the clamping and fixing of the gear, and then it is convenient to fix the rear end shaft of the motor. Thus, it effectively ensures that when the cooling fan is disassembled later, the rear end shaft of the motor is not prone to self-rotation, which affects the disassembly and assembly of the cooling fan, and at the same time, it effectively avoids accidental injury or damage between the cooling fan and the motor shaft during disassembly.
[0014] By setting the transmission components, on the one hand, while the fan cover is sleeved on the rear end of the motor body, the transmission blocks connected to each square-shaped plate can be accurately inserted into the gap between the first inclined surface and the third inclined surface. However, due to the setting of the second inclined surface and the fourth inclined surface and two fifth inclined surfaces provided on the transmission block, the transmission block can be accurately inserted into the gap, and each U-shaped guide rod can drive the arc-shaped tooth plate to move away from the gear, thereby canceling the clamping and fixing of the rear end shaft of the motor body. On the other hand, under the elastic force of the elastic piece, each transmission block can be pressed by the U-shaped guide rod in the gap, thereby realizing the preliminary pre-positioning of the fan cover. Therefore, when the multiple first bolts on the fan cover are tightened and fixed subsequently, the problem that the fan cover rotates and causes the bolt holes to be misaligned, affecting the assembly efficiency, can be avoided.

Detailed Description of the Embodiment
[0023] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although some embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. On the contrary, these embodiments are provided to more thoroughly and completely understand the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only for exemplary purposes and are not used to limit the protection scope of the present disclosure.
[0024] In addition, it should be noted that for ease of description, only parts related to the relevant invention are shown in the drawings. Without conflict, the embodiments in the present disclosure and the features in the embodiments can be combined with each other.
[0025] The present disclosure will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0026] This specific embodiment is a high-power control drive motor, as Figure 1-2 shown, the high-power control drive motor includes a motor main body 1. A fan cover 2 is fixed to the rear end of the motor main body 1 by a plurality of first bolts. A cooling fan 12 is sleeved on the rear end shaft 11 of the motor main body 1. A stopper 3 is installed at the rear end of the motor main body 1, and the stopper 3 is also connected to the rear end shaft 11. The stopper 3 is used to stop the rear end shaft 11. It further includes a transmission member 4. The transmission member 4 is used to cancel the stop of the rear end shaft 11. The transmission member 4 is installed on the inner wall of the fan cover 2 and is connected to the stopper 3.
[0027] Referring to Figure 3 、 Figure 5 and Figure 7 shown, in order to be able to actively fix the rear end of the motor main body 1 from rotating after the fan cover 2 is disassembled, the stopper 3 is provided to include an annular plate 31 fixed to the rear end of the motor main body 1 by a plurality of second bolts 33. A lightening slot 32 is provided on the annular plate 31 between every two adjacent second bolts 33. The lightening slots 32 are all in an arc-shaped structure. A U-shaped guide rod 34 is movably inserted in front of the annular plate 31 between every two adjacent lightening slots 32. On each U-shaped guide rod 34, the cross-section of the end far from the rear end shaft 11 is in a convex structure, and an arc-shaped tooth plate 35 is fixedly connected to the other end. Two moving channels matching with each U-shaped guide rod 34 are provided on the front side of the annular plate 31. The two moving channels are symmetrically distributed about the central axis of the same U-shaped guide rod 34. A gear 37 is fixedly connected to the outside of the rear end shaft 11 among the plurality of arc-shaped tooth plates 35. The arc-shaped tooth plates 35 are used to clamp and fix the gear 37. The arc surfaces of the plurality of arc-shaped tooth plates 35 facing away from the gear 37 are connected to the inner wall of the annular plate 31 through elastic pieces 36. The cross-sections of the elastic pieces 36 are all in a hourglass shape structure.
[0028] By providing the lightweight groove 32, the load gravity of the annular plate 31 on the motor body 1 after installation is reduced. Figure 2 The multiple transmission members 4 shown in the figure are in a state of squeezing the corresponding U-shaped guide rods 34, so that each U-shaped guide rod 34 drives the arc-shaped toothed plate 35 to move away from the gear 37, thereby realizing the cancellation of the stop of the rear end shaft 11 of the motor body 1. The two moving channels are respectively adapted to the shapes of the two side walls of the U-shaped guide rod 34, and the spring 36 is attached Figure 2 is in a compressed state, and the attached Figure 3 is in normal state.
[0029] Reference Figures 4 to 7 As shown, in order to enable the stopper 3 to jointly cancel the clamping fixation of the rear end shaft 11 of the motor body 1 while installing the fan cover 2, and to preliminarily pre-position the fan cover 2 when installing, the transmission member 4 is provided to include a plurality of annular arrays of square plates 41 arranged on the inner wall of the fan cover 2, each square plate 41 is fixed to the inner wall of the fan cover 2 by a third bolt 45, and a transmission block 42 is fixedly connected to one end of each square plate 41 facing the rear end shaft 11, and the interior of each transmission block 42 is a hollow structure, and the number of transmission blocks 42 is equal to the number of U-shaped guide rods 34. A fourth inclined surface 43 is provided at one end of each transmission block 42 facing the rear end of the motor body 1, and fifth inclined surfaces 44 are provided on both sides of each fourth inclined surface 43. On each U-shaped guide rod 34, a first inclined surface 341 matching with the fourth inclined surface 43 is provided on the inner wall on the side facing the outer side of the annular plate 31, and second inclined surfaces 342 provided on the inner wall of the U-shaped guide rod 34 are provided on both sides of each first inclined surface 341. The second inclined surfaces 342 match with the fifth inclined surface 44 on the corresponding side, and a third inclined surface 343 provided on the outer side of the annular plate 31 is also provided between every two second inclined surfaces 342.
[0030] By providing the square-shaped plate 41 and the hollow structure of the transmission block 42, the load gravity on the fan cover 2 can be reduced. At the same time, with the help of the design of each inclined surface, the transmission block 42 is more efficient when inserted into the gap between the first inclined surface 341 and the third inclined surface 343, and the transmission block 42 is more efficient when inserted into the gap between the first inclined surface 341 and the third inclined surface 343. Figure 7 It can be seen that a horizontal plane is also provided on the inner wall of the U-shaped guide rod 34 on one side facing the outer wall of the annular plate 31. After the transmission block 42 is inserted into the gap, the horizontal plane can overlap an outer surface of the transmission block 42 that is away from the rear end shaft 11 of the motor body 1, and under the setting of the spring piece 36, the fan cover 2 can be preliminarily pre-positioned, so that when the multiple first bolts are subsequently aligned and locked, it is not easy for the fan cover 2 to rotate and affect the assembly efficiency.
[0031] Working principle:
[0032] When disassembling the cooling fan 12, after loosening a plurality of first bolts, the fan cover 2 can be removed from the rear end of the motor body 1. During the removal, the fourth inclined surfaces 43 on each transmission block 42 respectively cancel the extrusion on the first inclined surface 341. At the same time, each U-shaped guide rod 34 drives the arc-shaped toothed plate 35 connected thereto to move towards the gear 37 under the rebounding action of the elastic piece 36, so as to realize the clamping and fixing of the gear 37, and further facilitate the fixing of the rear end shaft 11 of the motor body 1. Thus, it can effectively ensure that when the cooling fan 12 is disassembled subsequently, the rear end shaft 11 of the motor is not prone to self-rotation, which affects the disassembly and assembly of the cooling fan 12. At the same time, it can also effectively avoid accidental injuries or damages between the cooling fan 12 or the motor shaft during disassembly;
[0033] Secondly, after the cooling fan 12 is disassembled and the dust is cleaned, it is re-sleeved on the rear end shaft 11 of the motor body 1, and then the fan cover 2 is re-sleeved on the rear end of the motor body 1. During this process, the transmission blocks 42 connected to each square-shaped plate 41 are aligned and inserted into the gap between the first inclined surface 341 and the third inclined surface 343. However, due to the setting of the second inclined surface 342 and the fourth inclined surface 43 and the two fifth inclined surfaces 44 provided on the transmission block 42, the transmission block 42 can be accurately inserted into the gap, and each U-shaped guide rod 34 drives the arc-shaped toothed plate 35 to move away from the gear 37, so as to cancel the clamping and fixing of the rear end shaft 11 of the motor body 1. On the other hand, under the elastic force of the elastic piece 36, each transmission block 42 is pressed by the U-shaped guide rod 34 in the gap, so as to realize the preliminary pre-positioning of the fan cover 2, so that when the plurality of first bolts on the fan cover 2 are tightened and fixed subsequently, the problem that the fan cover 2 rotates and causes the bolt holes to be misaligned, affecting the assembly efficiency, can be avoided.

Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept.
