Description

Technical Field

[0001] This utility model relates to the field of motor end caps, and more specifically, to a high-strength, lightweight motor end cap. Background Technology

[0002] Motor end covers are an important component of a motor, located at both ends. They prevent dust, moisture, and debris from entering the motor, protecting internal components from mechanical impacts and damage. During installation, transportation, and use, the motor may be subjected to various external forces; the end covers provide cushioning and protection, reducing impact on internal components.

[0003] Existing motor end covers typically employ a one-piece structure. During the casting process, the complex shape and high requirements for integral molding make the process difficult, increasing the likelihood of casting defects and impacting product quality and production efficiency. Furthermore, the significant weight not only increases the overall weight of the motor, hindering installation, transportation, and use in applications with strict weight requirements, but may also increase energy consumption. Additionally, motors generate substantial heat during operation, and some motor end covers have poor heat dissipation, failing to effectively dissipate this heat and leading to excessively high internal motor temperatures, affecting motor performance and lifespan. Utility Model Content

[0004] The present invention aims to overcome the defects of the prior art and provide a high-strength, lightweight motor end cover.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a motor end cover, comprising an inner cover, an outer cover, and multiple elastic support units installed between the inner cover and the outer cover. The outer cover is provided with multiple insert plates arranged in a ring at equal intervals. The inner cover is provided with multiple clamping units arranged in a ring at equal intervals. Each clamping unit includes two clamping plates capable of clamping the insert plates. An elastic support unit is provided between two adjacent clamping units. Each elastic support unit includes a first arc-shaped spring, a second arc-shaped spring, and a connecting plate connecting the first and second arc-shaped springs. The first arc-shaped spring can abut against two adjacent clamping units, and the second arc-shaped spring can abut against two adjacent clamping units. Both the inner cover and the outer cover are made of aluminum alloy, and the insert plates, clamping plates, and elastic support units are all made of thermally conductive metal.

[0006] Furthermore, both ends of the first arc-shaped spring sheet are provided with first supporting protrusions, and the clamping plate is provided with a limiting plate for limiting the first supporting protrusions.

[0007] Thus, the first support protrusion increases the contact area at the end of the first arc-shaped spring piece, and can also be engaged at the limiting plate to prevent the elastic support unit from slipping off.

[0008] Furthermore, a second supporting protrusion is provided at both ends of the second arc-shaped spring piece.

[0009] This increases the contact area between the second arc-shaped spring and the clamping unit.

[0010] Furthermore, both the outer and inner covers have multiple annular ribs on their outer sides.

[0011] This improves heat dissipation and increases the strength of the motor end cover.

[0012] Furthermore, the insert plate, clamping plate, and elastic support unit are all made of aluminum alloy or copper.

[0013] This improves thermal conductivity.

[0014] Furthermore, the inner cover is provided with a plurality of first protruding plates, and the outer cover is provided with a plurality of second protruding plates. The first protruding plates have first mounting holes, and the second protruding plates have second mounting holes. The number of first mounting holes and second mounting holes are the same and they correspond one-to-one.

[0015] This facilitates the installation and fixation of the motor end cover of this application onto the motor housing.

[0016] Furthermore, the multiple first protruding plates are distributed in a ring at equal intervals.

[0017] Furthermore, multiple second protruding plates are distributed in a ring at equal intervals.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. The motor end cover of this application is divided into an inner cover and an outer cover. The split structure facilitates casting. It is made of aluminum alloy and has a hollow structure, which makes it lighter.

[0020] 2. The motor end cover of this application is provided with annular ribs and insert plates, thereby improving the overall mechanical strength, and the annular ribs improve the heat dissipation effect of the motor end cover.

[0021] 3. In this application, the motor end cover and the elastic support unit respectively abut against two adjacent clamping units, thereby helping the clamping plate to tightly clamp the insert plate and improving the heat conduction efficiency. Attached Figure Description

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.

[0033] This utility model provides, for example Figure 1-9The high-strength, lightweight motor end cover shown includes an inner cover 1, an outer cover 2, and multiple elastic support units installed between the inner cover 1 and the outer cover 2. The outer cover 2 has multiple insert plates 3 arranged in a ring with equal spacing. The inner cover 1 has multiple clamping units arranged in a ring with equal spacing on its inner side. Each clamping unit includes two clamping plates 4 capable of clamping the insert plates 3. An elastic support unit is disposed between two adjacent clamping units. Each elastic support unit includes a first arc-shaped spring piece 5.1, a second arc-shaped spring piece 5.2, and a connecting plate 5.3 connecting the first arc-shaped spring piece 5.1 and the second arc-shaped spring piece 5.2. The first arc-shaped spring piece 5.1 can abut against two adjacent clamping units, and the second arc-shaped spring piece 5.2 can abut against two adjacent clamping units. Both the inner cover 1 and the outer cover 2 are made of aluminum alloy, and the insert plates 3, clamping plates 4, and elastic support units are all made of thermally conductive metal.

[0034] Both ends of the first arc-shaped spring piece 5.1 are provided with first supporting protrusions 5.4, and the clamping plate 4 is provided with a limiting plate 4.1 for limiting the first supporting protrusions 5.4. Both ends of the second arc-shaped spring piece 5.2 are provided with second supporting protrusions 5.5. The outer cover 2 and the inner cover 1 both have multiple annular ribs 6 on their outer sides. The insert plate 3, the clamping plate 4, and the elastic support unit are all made of aluminum alloy or copper.

[0035] Working principle: The motor end cover of this application is divided into an inner cover and an outer cover. The split structure facilitates casting. It is made of aluminum alloy and has a hollow structure, thus making it lighter. The annular rib and insert plate improve the overall mechanical strength. The elastic support unit abuts against two adjacent clamping units, which helps the clamping plate to tightly clamp the insert plate. Furthermore, the annular rib, insert plate, and clamping plate improve the heat dissipation effect of the motor end cover.

[0036] During installation, first, the elastic support unit is installed on the inner cover, so that the first and second arc-shaped spring pieces abut against the two adjacent clamping units, and the limiting plate abuts against the corresponding first support protrusion, thereby limiting the elastic support unit. Next, the insert plate on the outer cover is inserted between the two clamping plates of the clamping unit. Under the action of the elastic support unit, the clamping unit tightly clamps the insert plate, thus achieving a tight connection between the inner cover and the outer cover. Finally, the inner cover and the outer cover are installed on the motor housing.

[0037] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes and modifications can be made to the present invention without departing from the scope defined by the claims.
