Description

Technical Field

[0001] This utility model relates to the field of motor assembly technology, specifically to a cast aluminum end cap with a heat dissipation structure. Background Technology

[0002] Cast aluminum is a process in which molten aluminum is poured into a mold and cooled to form an aluminum part of the desired shape. The castings obtained by casting aluminum are called cast aluminum parts. Because cast aluminum parts are low in cost, have good processability, and can be remelted and recycled to save resources and energy, most motor end caps are made of cast aluminum. The utility model patent application with publication number CN212366993U discloses a novel cast aluminum end cap structure, which has a simple processing procedure, uses fewer parts, and improves production efficiency. However, the end cover in the above solution has poor heat dissipation. If the motor continues to work for a long time, the heat inside the motor will accumulate and cannot be dissipated in a timely and effective manner, which will affect the service life of the motor and even cause damage. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, and several embodiments of the utility model will be provided. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and complete.

[0019] For examples, please refer to Figure 1 - Figure 4 This utility model provides a technical solution: A cast aluminum end cap with a heat dissipation structure includes an end cap body 1, a mounting base 2 fixedly connected to the bottom of the outer wall of the end cap body 1, a shaft hole 3 opened at the center of the end cap body 1, heat dissipation holes 5 equidistantly opened at the top of the end cap body 1, a heat conduction plate 6 equidistantly passing through the top of the end cap body 1, a ventilation and dustproof net 7 provided on the inner side of the end cap body 1, positioning components 4 for positioning the ventilation and dustproof net 7 symmetrically arranged on both sides of the end cap body 1, and positioning holes 8 symmetrically opened on both side walls of the ventilation and dustproof net 7. The positioning component 4 includes fixed housings 401 disposed on both sides of the end cap body 1. The two fixed housings 401 are fixedly connected to the outer wall of the end cap body 1 on the side that is close to each other. The top of the two fixed housings 401 is symmetrically provided with sliding grooves 402. The top of the two fixed housings 401 is provided with moving rods 403 through the sliding grooves 402. The inner cavities of the two fixed housings 401 are each provided with a sliding block 404. The outer walls of the two sliding blocks 404 are slidably connected to the inner walls of the two fixed housings 401 respectively. The interiors of the two sliding blocks 404 are each provided with a guide rod 405. The two ends of the two guide rods 405 are fixedly connected to the inner walls of the two sides of the two fixed housings 401 respectively. The inner walls of the two sliding blocks 404 are slidably connected to the outer walls of the two guide rods 405 respectively. The tops of the two sliding blocks 404 are fixedly connected to the bottoms of the two moving rods 403 respectively. A spring 406 is sleeved on the outer wall of the two guide rods 405 away from the end cap body 1. A positioning rod 407 is fixedly connected to the bottom of the two sliding blocks 404 on the side closer to each other. The ends of the two positioning rods 407 away from the sliding blocks 404 penetrate the side wall of the end cap body 1 and are respectively inserted into the interior of the two positioning holes 8. The heat dissipation holes 5 are arranged in a ring array with the center of the shaft hole 3 as the center. The heat conduction plate 6 is also arranged in the same way. The heat dissipation holes 5 and the heat conduction plate 6 are arranged in an alternating pattern. The ventilation and dustproof mesh 7 has a central through hole at its center, which is corresponding to the shaft hole 3. The heat conduction plate 6 is made of aluminum.

[0020] Among them, the heat dissipation hole 5 increases the air circulation area and accelerates the heat dissipation. Another part of the heat is absorbed by the heat conduction plate 6. Since the heat conduction plate 6 is made of aluminum, it has good thermal conductivity and can quickly conduct heat from the inside of the motor to the outside of the end cover body 1 to ensure the normal operation of the motor. Furthermore, air enters the end cover body 1 through the ventilation and dustproof mesh 7. The ventilation and dustproof mesh 7 filters the air, effectively blocking dust and impurities from entering the motor; thus avoiding motor failure caused by dust accumulation. In this embodiment, the moving rod 403 is pulled to both sides, and the moving rod 403 drives the sliding block 404 to slide on the guide rod 405 to compress the spring 406. The positioning rod 407 is pulled out from the positioning hole 8. At this time, the ventilation dustproof net 7 can be taken out from the inside of the end cover body 1. After cleaning or replacement, the normal operation of the motor is ensured.

[0021] The working process of this utility model is as follows: During use, the mounting base 2 of the end cover body 1 is fixedly connected to the motor housing, so that the end cover body 1 is stably installed on the motor. The heat generated by the motor during operation is partially dissipated through the evenly distributed heat dissipation holes 5. The heat dissipation holes 5 increase the air circulation area and accelerate the heat dissipation. The other part of the heat is absorbed by the heat conduction plate 6. Since the heat conduction plate 6 is made of aluminum, it has good thermal conductivity and can quickly conduct heat from the inside of the motor to the outside of the end cover body 1. At the same time, air enters the inside of the end cover body 1 through the ventilation and dustproof net 7. The ventilation and dustproof net 7 filters the air and effectively blocks dust and impurities from entering the inside of the motor. When it is necessary to clean or replace the ventilation and dustproof net 7, simply pull the moving rod 403 to both sides. The moving rod 403 drives the sliding block 404 to slide on the guide rod 405 to compress the spring 406. The positioning rod 407 is pulled out from the positioning hole 8. At this time, the ventilation and dustproof net 7 can be removed from the inside of the end cover body 1. After cleaning or replacement, the normal operation of the motor is guaranteed.

[0022] All standard parts used in this application can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art and are also general components, which are common knowledge in this field.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
