Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor technology, specifically to a motor with a porous heat dissipation structure. Background Technology
[0002] An electric motor typically includes a stator and a rotor. The stator includes a housing, a stator core fixed inside the housing, and stator windings wound around the stator core. The rotor includes a shaft, a rotor core sleeved on the shaft, and multiple permanent magnets.
[0003] However, in order to dissipate the heat generated inside the motor during use, heat dissipation holes are opened on the motor housing. After long-term use, a lot of dust will accumulate inside the heat dissipation holes, blocking them and reducing heat dissipation efficiency, thus affecting the dissipation of heat inside the motor. Utility Model Content
[0004] The purpose of this invention is to provide a motor with a porous heat dissipation structure to solve the problem mentioned in the background art where a large amount of dust accumulates inside the heat dissipation holes, clogging them.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a motor with a porous heat dissipation structure, comprising:
[0006] The motor body has a heat dissipation component at the rear and a locking component on the output shaft of the motor body.
[0007] A heat dissipation assembly includes a heat dissipation perforated plate, the outer wall of which abuts against a limiting rotating plate, a fixing rod passing through the middle of the limiting rotating plate, and a screw ring abutting against the upper side of the limiting rotating plate.
[0008] Preferably, the locking assembly includes a fixing block, a lead screw passing through the interior of the fixing block, a nut assembly connected to the upper outer wall of the lead screw, a rudder fixedly disposed on the outer wall of the nut assembly, a broken tooth fixedly installed below the lead screw, and a toothed ring meshing below the broken tooth.
[0009] Preferably, the limiting rotating plate is rotatably connected to the fixing rod, and the two ends of the fixing rod are fixedly connected to the motor body through the fixing plate.
[0010] Preferably, the screw ring is threadedly connected to the motor body, and the fixing block is fixedly connected to the motor body.
[0011] Preferably, the lead screw and the fixed block are in a sliding connection.
[0012] Preferably, the rudder can rotate around the lead screw on the surface of the fixed block, and one side of the missing tooth is in contact with the surface of the motor body.
[0013] Preferably, the inner wall of the gear ring is fixedly connected to the output shaft of the motor body.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] (1) The motor of this utility model has a heat dissipation component. The heat dissipation plate is set at the heat dissipation position. The multi-hole heat dissipation improves the heat dissipation efficiency. When a lot of dust accumulates on the inside of the heat dissipation plate, the screw ring can be turned away from the limit plate and no longer presses against the limit plate. When the heat dissipation plate is removed, the limit plate will rotate around the fixed rod. The removed heat dissipation plate can be replaced or cleaned. The operation is simple and quick, which improves the practicality.
[0016] (2) With the setting of the locking component, when the motor body stops operating, the rudder can be rotated. The rudder drives the nut pair to rotate, the nut pair drives the lead screw to move downward, and the lead screw drives the missing tooth to move downward, so that the missing tooth meshes with the tooth ring, thereby limiting the output shaft of the motor body on the inner wall of the tooth ring, preventing the output shaft from rotating after the motor body is accidentally started, thus improving safety.

Detailed implementation method:
[0023] 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.
[0024] Please see Figure 1-5 One embodiment of this utility model is a motor with a porous heat dissipation structure. The motor body 01 and nut pair 33 used in this application are products that can be directly purchased on the market. Their principles and connection methods are existing technologies known to those skilled in the art, so they will not be described in detail here.
[0025] Includes: a motor body 01, a heat dissipation component 02 located at the rear of the motor body 01, and a locking component 03 located on the output shaft of the motor body 01;
[0026] The heat dissipation assembly 02 includes a heat dissipation perforated plate 21. The outer wall of the heat dissipation perforated plate 21 abuts against a limiting rotating plate 22. After the screw ring 24 no longer abuts against the limiting rotating plate 22, the limiting rotating plate 22 can rotate around the fixing rod 23 without affecting the removal of the heat dissipation perforated plate 21. The fixing rod 23 passes through the middle of the limiting rotating plate 22. The upper side of the limiting rotating plate 22 abuts against a screw ring 24. When the screw ring 24 is turned, it abuts against the limiting rotating plate 22, so that the lower part of the limiting rotating plate 22 abuts against the heat dissipation perforated plate 21, thus limiting the heat dissipation perforated plate 21.
[0027] Furthermore, the locking assembly 03 includes a fixing block 31, through which a lead screw 32 passes. The movement of the lead screw 32 can drive the missing tooth 35 to move up and down, thereby engaging or disengaging the missing tooth 35 with the toothed ring 36. A nut pair 33 is connected to the upper outer wall of the lead screw 32. A rudder 34 is fixedly installed on the outer wall of the nut pair 33. After the rudder 34 rotates, it can drive the nut pair 33 to rotate, thereby driving the lead screw 32 to move up and down. The missing tooth 35 is fixedly installed below the lead screw 32. The missing tooth 35 is in contact with the surface of the motor body 01. The missing tooth 35 can only move up and down and cannot rotate, thus playing a guiding role. The toothed ring 36 is engaged below the missing tooth 35. When the toothed ring 36 engages with the missing tooth 35, the toothed ring 36 can limit the output shaft of the motor body 01.
[0028] Furthermore, the limiting rotating plate 22 is rotatably connected to the fixing rod 23. After the screw ring 24 no longer abuts against the limiting rotating plate 22, the limiting rotating plate 22 can rotate around the fixing rod 23 without affecting the removal of the heat dissipation plate 21. The two ends of the fixing rod 23 are fixedly connected to the motor body 01 through the fixing plate to ensure the firmness of the fixing rod 23.
[0029] Furthermore, the screw ring 24 is threadedly connected to the motor body 01. When the screw ring 24 is turned, it presses against the limiting rotating plate 22, which causes the lower part of the limiting rotating plate 22 to press against the heat dissipation plate 21, thus limiting the heat dissipation plate 21. The fixing block 31 is fixedly connected to the motor body 01 to ensure the firmness of the position of the toothed ring 36.
[0030] Furthermore, the lead screw 32 is slidably connected to the fixed block 31 to ensure that the fixed block 31 does not affect the movement of the lead screw 32. The movement of the lead screw 32 can drive the missing tooth 35 to move up and down, thereby engaging the missing tooth 35 with the tooth ring 36 or moving it away from the tooth ring 36.
[0031] Furthermore, the rudder 34 can rotate around the lead screw 32 on the surface of the fixed block 31. After the rudder 34 rotates, it can drive the nut pair 33 to rotate, thereby driving the lead screw 32 to move up and down. One side of the missing tooth 35 is in contact with the surface of the motor body 01. The missing tooth 35 can only move up and down and cannot rotate, thus playing a guiding role.
[0032] Furthermore, the inner wall of the gear ring 36 is fixedly connected to the output shaft of the motor body 01. When the gear ring 36 meshes with the missing tooth 35, the gear ring 36 can limit the output shaft of the motor body 01.
[0033] Working principle: In use, the heat dissipation plate 21 is first placed in the heat dissipation position. When a large amount of dust accumulates inside the heat dissipation plate 21, the screw ring 24 can be turned away from the limiting rotating plate 22, no longer pressing against it. The heat dissipation plate 21 can then be removed. When the motor body 01 stops operating, the rudder 34 can be rotated. The rudder 34 drives the nut assembly 33 to rotate, which in turn drives the lead screw 32 to move downwards. The lead screw 32 drives the missing tooth 35 to move downwards, causing the missing tooth 35 to mesh with the gear ring 36, thereby limiting the output shaft of the motor body 01 on the inner wall of the gear ring 36. The above is the complete working principle of this utility model.
[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
