Description

Technical Field

[0001] This utility model relates to the field of motors, and more specifically, to a motor end cover. Background Technology

[0002] The motor end cover is an important component of the motor housing. Its main function is to enclose the internal structure of the motor, providing support, protection, and sealing.

[0003] To ensure the overall heat dissipation speed of the motor, existing motor end covers have some heat dissipation holes to improve the overall heat dissipation effect of the motor casing. Due to the opening of the heat dissipation holes, external dust can easily enter the motor through the heat dissipation holes. To reduce this phenomenon, filter sheets are added inside the heat dissipation holes to reduce the entry of dust. However, the filter sheets are generally fixed to the inner wall of the heat dissipation holes by welding. When cleaning the motor end cover, people also need to clean the filter sheets. Because the filter sheets are located in the heat dissipation holes and the area inside the heat dissipation holes is relatively small, it is not easy to wipe the filter sheets.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a motor end cover.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a motor end cover, including a housing, the housing having a plurality of heat dissipation holes, the outer wall of the housing having a rotating groove communicating with the heat dissipation holes, a rotating seat being rotatably connected in the rotating groove, a filter sheet located in the heat dissipation holes being provided on the rotating seat, the rotating seat being able to drive the filter sheet to rotate toward the outside of the housing, the inner wall of the rotating seat facing the heat dissipation holes having a rotating groove, the filter sheet being rotatably connected in the rotating groove.

[0007] The present invention is further configured such that: a limiting strip is fixedly connected to the filter sheet, and a limiting groove is formed on the inner wall of the rotating groove.

[0008] The present invention is further configured such that: the filter sheet includes a filter part and a recessed part, the filter part is provided with a plurality of filter holes, the upper and lower sides of the recessed part are not on the same plane as the upper and lower sides of the filter part, and the limiting strip is located on the outer edge of the filter part and the two ends of the limiting strip are close to the recessed part.

[0009] The present invention is further configured such that: the filter part is rigid, the recessed part is elastic, and a protrusion is fixedly connected to the inner peripheral wall of the heat dissipation hole; when the filter sheet is located inside the heat dissipation hole, the side of the recessed part facing the outside of the housing abuts against the protrusion.

[0010] The present invention is further configured such that the protrusion is hemispherical.

[0011] The present invention is further configured such that the shell is made of cast iron.

[0012] In summary, this utility model has the following beneficial effects:

[0013] When the housing needs cleaning, the housing is removed from the motor, and the filter is flipped out from the heat dissipation hole. This arrangement not only provides ample space around the filter but also prevents the outer edge of the filter from contacting the inner wall of the heat dissipation hole, thus eliminating the dead corner between the outer edge of the filter and the inner wall of the heat dissipation hole. The filter can be cleaned by wiping the inner wall of the heat dissipation hole and the outer edge of the filter. At the same time, the filter can be rotated during wiping, causing it to rotate relative to the rotating base. This allows the outer edge of the filter, which is close to the rotating base, to rotate to a position away from the rotating base, making it easier to wipe all areas and facilitating the cleaning of the filter.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] A type of motor end cover, such as Figure 1 and Figure 2As shown, the device includes a housing 1 with several heat dissipation holes 2. A rotating groove 3 communicating with the heat dissipation holes 2 is formed on the outer wall of the housing 1. A rotating seat 4 is rotatably connected within the rotating groove 3. A filter element 5 is mounted on the rotating seat 4, located within the heat dissipation holes 2. The rotating seat 4 can only rotate the filter element 5 towards the outside of the housing 1. A rotating groove 3 is formed on the inner wall of the rotating seat 4 facing the heat dissipation holes 2, and the filter element 5 is rotatably connected within the rotating groove 3. When the filter element 5 is located within the heat dissipation holes 2, the lower side of the rotating seat 4 abuts against the bottom wall of the rotating groove 3. This arrangement prevents the filter element 5 from rotating towards the inside of the housing 1 when it is within the heat dissipation holes 2, thus preventing contact between the filter element 5 and the internal structure of the motor. This design allows for cleaning of the housing 1. When the housing 1 is removed from the motor, the filter 5 is flipped out from the heat dissipation hole 2. This arrangement not only provides a larger space around the filter 5, but also makes it less likely for the outer edge of the filter 5 to contact the inner wall of the heat dissipation hole 2. This eliminates the dead corner between the outer edge of the filter 5 and the inner wall of the heat dissipation hole 2. The filter 5 can be cleaned by wiping the inner wall of the heat dissipation hole 2 and the outer edge of the filter 5. At the same time, the filter 5 can be rotated during the wiping process. The filter 5 will rotate relative to the rotating seat 4, allowing the outer edge of the filter 5, which is close to the rotating seat 4, to rotate to a position away from the rotating seat 4. This makes it easier to wipe all parts of the filter 5 and facilitates the cleaning of the filter 5.

[0020] like Figure 2 and Figure 3 As shown, a limiting strip 7 is fixedly connected to the filter element 5, and a limiting groove 6 is formed on the inner wall of the rotating groove 3. By setting the limiting strip 7, the limiting strip 7 can restrict the filter element 5 from separating from the rotating seat 4 in the horizontal direction, thereby preventing the filter element 5 from separating from the rotating seat 4 and ensuring the stability of the filter element 5 and the rotating seat 4. The filter element 5 includes a filter part 8 and a recessed part 9. The filter part 8 has several filter holes. The upper and lower sides of the recessed part 9 are not on the same plane as the upper and lower sides of the filter part 8. The limiting strip 7 is located on the outer edge of the filter part 8, and the two ends of the limiting strip 7 are set close to the recessed part 9. The setting of the recessed part 9 restricts the relative rotation of the filter element 5 and the rotating seat 4. Because the recessed part 9 and the filter part 8 are not on the same plane, when the rotating seat 4 abuts against the recessed part 9, the limiting strip 7 is still located in the limiting groove 6, so that the limiting strip 7 will not detach from the rotating seat 4 during rotation.

[0021] like Figure 2 and Figure 3As shown, the filter part 8 is rigid, the recessed part 9 is elastic, and a protrusion 10 is fixedly connected to the inner peripheral wall of the heat dissipation hole 2. When the filter element 5 is located inside the heat dissipation hole 2, the side of the recessed part 9 facing the outside of the housing 1 abuts against the protrusion 10, and the recessed part 9 can deform up and down to a certain extent. The filter part 8 is made of rigid material, and its deformation is relatively small. When the filter element 5 is located inside the heat dissipation hole 2, the upper side of the recessed part 9 is abutted by the protrusion 10, thereby limiting the rotation of the filter element 5 behind the protrusion 10, so that the filter element 5 will not rotate when the air passes through it. When people need to turn the filter element 5, they press the filter part 8 from the inside of the housing 1. At this time, the recessed part 9 is abutted by the protrusion 10, thereby deforming to a certain extent. Freed from the constraint of the protrusion 10, and due to the relatively small degree of deformation, the deformation of the recessed part 9 is elastic. The engagement of the protrusion 10 ensures the stability of the filter sheet 5 within the heat dissipation hole 2, and also facilitates the flipping of the filter sheet 5 outwards. Furthermore, when the housing 1 is mounted on the motor, the filter sheet 5 is not easily flipped because there is no force application point on it. Several friction grooves are provided in the middle of the limiting strip 7. The friction grooves increase the friction between the limiting strip 7 and the inner wall of the limiting groove 6. When the recessed part 9 rotates to a position that can engage with the protrusion 10, the inner wall of the limiting groove 6 provides a relatively large friction force to the limiting strip 7, which reduces the degree of rotation of the filter sheet 5 during the engagement of the recessed part 9 and the protrusion 10.

[0022] like Figure 3 As shown, the protrusion 10 is hemispherical. The hemispherical protrusion 10 makes the outer wall of the protrusion 10 an arc surface. The arc surface abuts against the recessed part 9, making the recessed part 9 more likely to deform, which makes it easier for people to flip the filter 5 outward. The shell 1 is made of cast iron. Cast iron has the characteristics of high strength and long service life, thus ensuring the overall strength and service life of the shell 1.
