It is the rotating shaft connecting the motor and the reducer, acting as a link for electromechanical energy conversion between the motor and the equipment.

[0003] Currently, the main component of an existing motor shaft is a connecting shaft. When the motor is in actual use, even if the motor speed can meet the requirements, the torque is only transmitted through the connecting shaft, resulting in a small torque transmitted by the motor. This makes it unsuitable for use when the torque requirement is high, which can easily lead to motor overload damage and poor practicality. In view of this, this application proposes a motor shaft mechanism. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a motor shaft mechanism, comprising:

[0028] The motor spindle 100 has a motor output shaft 200 at its end, and the motor spindle 100 is located at the output end of the motor body 300.

[0029] The switching assembly 400 is used to switch the output torque of the motor. The switching assembly 400 includes a connecting box 401 disposed between the motor main shaft 100 and the motor output shaft 200. The outer surface of the connecting box 401 has a plurality of mounting posts fixedly arranged in a circumferential array and fixedly connected to the surface of the motor body 300 housing. Rotating holes are opened on both sides of the connecting box 401, and the inner walls of two rotating holes are respectively rotatably connected to the surfaces of the motor main shaft 100 and the motor output shaft 200 through two bearings. The ends of the motor main shaft 100 and the motor output shaft 200 are respectively fixed... The switching assembly 400 includes a first gear 402 and a second gear 403. It also includes a first sliding frame 404 and a second sliding frame 405 that are slidably disposed on the inner wall of the connecting box 401. A first rotating shaft 406 is rotatably disposed on the inner wall of the first sliding frame 404. A first reduction gear 407 and a second reduction gear 408 are fixedly disposed on the surface of the first rotating shaft 406. A third gear 409 is fixedly disposed on the surface of the motor output shaft 200. The first reduction gear 407 corresponds to the first gear 402, and the second reduction gear 408 corresponds to the third gear 409.

[0030] See Figure 2 and Figure 3 The first gear 402 and the second gear 403 have the same specifications, and the first reduction gear 407 and the third gear 409 have the same specifications, which are twice the specifications of the first gear 402 and the second gear 403.

[0031] Specifically, the rotation of the first gear 402 can drive the first reduction gear 407 and the second reduction gear 408 to rotate at a reduced speed. At the same time, the rotation of the second reduction gear 408 can drive the third gear 409 to rotate at a reduced speed, thereby driving the motor output shaft 200 to rotate at a reduced speed, thus achieving the purpose of increasing the torque of the motor body 300.

[0032] See Figure 2 The outer surface of the connecting box 401 is rotatably provided with a threaded post 4010 extending into the interior of the connecting box 401, and the surface of the first sliding frame 404 is provided with a threaded hole that is threadedly connected to the outer surface of the threaded post 4010. A limiting block is fixed at one end of the threaded post 4010, and a rotating disk 4011 is fixed at the other end of the threaded post 4010.

[0033] Specifically, by setting the threaded post 4010, the rotation of the threaded post 4010 can drive the first sliding frame 404 to move automatically.

[0034] See Figure 2 The inner wall of the connecting box 401 is fixed with two first limiting rods 4012 corresponding to the threaded post 4010, and the surface of the first sliding frame 404 is provided with sliding holes that are slidably connected to the outer surfaces of the two first limiting rods 4012.

[0035] Specifically, by setting the first limiting rod 4012, the stability of the first sliding frame 404 during movement is effectively guaranteed.

[0036] See Figure 3 and Figure 4 Two symmetrical connecting rods 4013 are fixedly provided at the end of the second sliding frame 405, and the other end of the two connecting rods 4013 is fixedly connected to the end of the first sliding frame 404.

[0037] Specifically, by setting two connecting rods 4013, the movement of the first sliding frame 404 can drive the movement of the second sliding frame 405.

[0038] In this invention, by setting a switching component 400, the motor shaft mechanism can rotate the rotating disk 4011 to drive the threaded column 4010 to rotate when the motor body 300 is used in an environment requiring high torque. The rotation of the threaded column 4010 drives the first sliding frame 404 to move. The movement of the first sliding frame 404 drives the first reduction gear 407 and the second reduction gear 408 to approach the first gear 402 and the third gear 409 respectively, and they mesh with each other. At this time, when the motor body 300 drives the motor main shaft 100 to rotate, it can drive the first reduction gear 407, the first rotating shaft 406, and the second reduction gear 408 to rotate through the first gear 402, thereby driving the third gear 409 and the motor output shaft 200 to rotate. This achieves the purpose of multi-gear reduction and effectively increases torque, thus enabling the motor shaft mechanism to meet the requirements of use in environments with high torque, making it highly practical.

[0039] See Figure 2 The inner wall of the second sliding frame 405 is rotatably provided with a second rotating shaft 4014, and the surface of the second rotating shaft 4014 is fixed with two fourth gears 4015 respectively corresponding to the first gear 402 and the second gear 403.

[0040] Specifically, by setting a fourth gear 4015, two fourth gears 4015 can mesh with the first gear 402 and the second gear 403 respectively, so that the motor body 300 can be used in a normal environment.

[0041] See Figure 2 A limiting block is fixed on the surface of the second sliding frame 405, and a second limiting rod 4016 corresponding to the limiting block is fixed on the inner wall of the connecting box 401. A through hole is opened on the surface of the limiting block to slide and connect with the surface of the second limiting rod 4016.

[0042] Specifically, by setting the second limit rod 4016, the stability of the second sliding frame 405 during movement is effectively guaranteed.

[0043] Meanwhile, the technical solution proposed by this utility model, when the motor body 300 is in normal use, can reverse the rotation of the rotating disk 4011 to drive the first sliding frame 404 to move in the opposite direction, so that the first reduction gear 407 and the second reduction gear 408 are respectively away from the first gear 402 and the third gear 409. At the same time, the reverse movement of the first sliding frame 404 drives the second sliding frame 405 to move in the opposite direction, thereby driving the fourth gear 4015 on the second sliding frame 405 to mesh with the first gear 402 and the second gear 403 respectively. This achieves the purpose of driving the motor output shaft 200 to rotate normally when the motor body 300 rotates, and enables the motor shaft mechanism to quickly switch between normal torque mode and high torque mode, further improving the practicality of the motor shaft mechanism.

[0044] Working Principle: In actual use, when the motor body 300 is used in an environment requiring high torque, the rotating disk 4011 rotates, causing the threaded column 4010 to rotate. The rotation of the threaded column 4010 causes the first sliding frame 404 to move. The movement of the first sliding frame 404 causes the first reduction gear 407 and the second reduction gear 408 to approach the first gear 402 and the third gear 409 respectively, and mesh with them. At this time, while the motor body 300 is driving the motor main shaft 100 to rotate, it can drive the first reduction gear 407, the first rotating shaft 406, and the second reduction gear 408 to rotate through the first gear 402, thereby driving the third gear 409 and the motor output shaft 200 to rotate, thus achieving multi-gear reduction and effectively increasing torque. The purpose of this design is to enable the motor shaft mechanism to operate under conditions of high torque, making it highly practical. Furthermore, when the motor body 300 is in normal use, the reverse rotation of the rotating disk 4011 causes the first sliding frame 404 to move in the opposite direction, displacing the first reduction gear 407 and the second reduction gear 408 away from the first gear 402 and the third gear 409, respectively. Simultaneously, the reverse movement of the first sliding frame 404 causes the second sliding frame 405 to move in the opposite direction, thereby engaging the fourth gear 4015 on the second sliding frame 405 with the first gear 402 and the second gear 403. This achieves the goal of normally driving the motor output shaft 200 to rotate when the motor body 300 rotates, enabling the motor shaft mechanism to quickly switch between normal torque mode and high torque mode, further improving its practicality.

[0045] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
