[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0029] Reference Figures 1-6 A kind of outer rotor motor protective support, comprising:

[0030] Positioning ring body 100 is connected to motor outer rotor;

[0031] Multiple protective supports 101 are arranged outside positioning ring body 100;

[0032] Connecting boss 102 is arranged on positioning ring body 100;

[0033] Assembly component is arranged between connecting boss 102 and protective support 101, for moving the position of protective support 101 when rotating connecting boss 102, multiple protective supports 101 are synchronously moved;

[0034] Among them, protective support 101 includes spoiler opening 103 arranged on it;

[0035] By setting the positioning ring body 100, when applied, the positioning ring body 100 can be fixed on the outer rotor of the outer rotor motor by using fasteners such as bolts, and in the initial state, the plurality of protective supports 101 on the positioning ring body 100 are on the outer side wall of the motor outer rotor and are uniformly distributed, and when assembling, the rotating connection boss 102 is rotated to move the protective supports 101 through the assembly parts, and the plurality of protective supports 101 move synchronously until the protective supports 101 contact the outer rotor of the motor. The synchronous movement design of the plurality of protective supports 101 enables the protective structure to be flexibly adjusted according to the actual use environment, and after the protective supports 101 move to the predetermined position, the spoiler opening 103 can guide the airflow to flow through the surface of the outer rotor during the operation of the motor, forming an effective heat dissipation channel, thereby improving the heat dissipation efficiency of the motor. In the process of high-speed rotation, stable airflow distribution is generated to prevent local overheating phenomenon. The protective supports 101 cover the surface of the motor outer rotor, effectively block the direct contact of external objects, prevent external collision damage to the motor outer rotor, and provide additional physical protection. In summary, the protective supports 101 not only protect the motor from the external environment, but also optimize the heat dissipation effect while ensuring the stable operation of the motor, achieve the balance of heat dissipation and protection, and solve the problem that the protective device in the prior art cannot meet the needs of motor heat dissipation and protection.

[0036] Further, the protective supports 101 are provided with flow-through channels 104 on the side close to the motor outer rotor, which are communicated with the spoiler openings 103.

[0037] By setting the flow-through channels 104, the side of the protective supports 101 close to the motor outer rotor can further optimize the airflow path. After the flow-through channels 104 are communicated with the spoiler openings 103, during high-speed rotation of the motor, the airflow can not only be guided into the spoiler openings 103, but also be more effectively dispersed and discharged through the flow-through channels 104, thereby forming a continuous airflow circulation on the surface of the motor outer rotor. This design can significantly improve the heat dissipation efficiency of the motor and reduce the problem of excessive temperature caused by local airflow stagnation. In addition, the setting of the flow-through channels 104 can also reduce the influence of external air pressure fluctuations on the operation of the motor to a certain extent. With the orderly arrangement of the airflow through the flow-through channels 104 and the spoiler openings 103, the airflow distribution is more uniform, which helps to reduce air resistance and turbulence generated during rotation and ensures that the motor remains stable during high-speed operation.

[0038] Further, the spoiler openings 103 are connected with a plurality of inclined heat dissipation blades 105.

[0039] By setting the heat dissipation blades 105, the airflow is further guided and accelerated when passing through the spoiler openings 103. The multiple obliquely arranged heat dissipation blades 105 not only enhance the flowability of the air, but also disperse the airflow more evenly on the surface of the motor outer rotor, forming a stable airflow circulation, thereby significantly improving the heat dissipation effect of the motor. The oblique design of the heat dissipation blades 105 can accelerate the airflow through the blades by utilizing the centrifugal force generated by rotation when the motor rotates, while reducing the resistance of the airflow. This design can effectively reduce the temperature of the motor surface and avoid the occurrence of local overheating, especially in high-load or high-temperature environments, the heat dissipation blades 105 can continuously help the motor maintain a suitable working temperature and prolong the service life of the motor.

[0040] Further, the assembly part includes a connecting frame 200 connected to the protective support 101, the connecting frame 200 is slidably connected with the positioning ring body 100, and a lead screw 201 threadedly connected with the connecting frame 200 is rotatably connected to the positioning ring body 100.

[0041] By setting the connecting frame 200, the movement and adjustment of the protective support 101 become more flexible and accurate. The connecting frame 200 is slidably connected with the positioning ring body 100 and is controlled by the threaded lead screw 201, which can realize the stable movement of the protective support 101 on the positioning ring body 100. When the lead screw 201 rotates, the connecting frame 200 slides, thereby driving the synchronous displacement of the protective support 101. This design not only ensures that the protective support 101 remains stable during adjustment, but also effectively prevents structural loosening or deviation caused by improper movement. Through the threaded connection of the lead screw 201 and the connecting frame 200, the operator can conveniently control the position of the protective support 101 without the need for complex tools or tedious operations. When the protective support 101 needs to fit the surface of the motor outer rotor to enhance protection, only the lead screw 201 needs to be rotated to accurately move the protective support 101 into position.

[0042] Further, the connecting boss 102 is connected with a first gear 202, the lead screw 201 is connected with a second gear 203 engaged with the first gear 202, and the connecting boss 102 is rotatably connected to the positioning ring body 100.

[0043] The first gear 202 is connected to the connecting boss 102 and meshes with the second gear 203 on the lead screw 201. When the connecting boss 102 is rotated, the first gear 202 drives the second gear 203 to rotate synchronously, thereby driving the rotation of the lead screw 201. This gear meshing transmission mode can achieve precise control of the protective bracket 101, further improving the sensitivity of the adjustment. When the operator rotates the connecting boss 102, the gear system can effectively transmit force to the lead screw 201, making the movement of the protective bracket 101 more stable and uniform. Compared with the manual adjustment of the lead screw 201, the gear transmission reduces friction and resistance, improves the adjustment efficiency, especially in the case of multiple protective brackets 101 or frequent adjustment, which can significantly reduce the difficulty and workload of adjustment. In addition, the gear transmission system can also ensure the synchronization during the adjustment process, and multiple protective brackets 101 can move synchronously under the drive of the gear transmission, avoiding the problem of uneven protection or unbalanced heat dissipation caused by the asynchronous position of individual protective brackets 101. Through this precise gear transmission structure, the entire protection system not only has the convenience of operation, but also ensures the reliability and stability for a long time.

[0044] Further, the second gear 203 is provided with a ratchet mechanism 204 between the lead screw 201, and the other end of the lead screw 201 is connected with a hexagonal cap 205.

[0045] By setting the ratchet mechanism 204, the ratchet mechanism 204 is limited to rotate only in one direction, thereby avoiding unnecessary reverse movement of the protective bracket 101 during operation. This design plays a role in stabilizing the position of the protective bracket 101 when the motor outer rotor rotates at high speed, preventing the lead screw 201 from rotating in the opposite direction due to external vibration or centrifugal force, thereby affecting the normal position and protection effect of the protective bracket 101. The one-way limit of the ratchet mechanism 204 can ensure that the lead screw 201 remains stable after the protective bracket 101 is adjusted to the predetermined position, and will not back off due to high-speed rotation of the motor or external impact. This not only improves the fixing reliability of the protective bracket 101, but also reduces the maintenance workload caused by frequent adjustment of the bracket position. The other end of the lead screw 201 is connected with a hexagonal cap 205, through which the operator can manually adjust when needed. When the motor stops or needs to be repaired, a simple tool can be used to fine-tune or reset the position of the protective bracket 101 through the hexagonal cap 205. The above design improves the stability and operability of the protective bracket 101, while taking into account the reliability and safety during long-term use.
