Description

Technical Field

[0001] The utility model relates to the field of motor cover plates, in particular to a plastic motor cover plate integrally formed with a radiator. Background Art

[0002] The motor cover is a plate-like component covering the motor casing. It is usually used to protect the internal parts of the motor from the influence of the external environment and provide mechanical support and structural support. The motor cover plays an important role in protecting and supporting the motor during operation, ensuring that the motor can operate safely and stably, extending its service life, and reducing maintenance costs.

[0003] However, most of the plastic motor covers now have the following problems:

[0004] Existing motor covers, traditional motor covers adopt an all-aluminum structural design, and the blank still needs secondary processing after die-casting. The sealing effect of the connector installation position is poor, and the weight is heavy and the cost is high. At the same time, in order to improve the heat dissipation efficiency, most of the heat dissipation is handled through the aluminum structure. A large amount of aluminum increases the weight of the equipment and the production cost increases, which is inconvenient to reduce the production cost and improve the heat dissipation efficiency.

[0005] Therefore, we have made improvements to this problem and proposed a plastic motor cover with an integrally molded radiator. Utility Model Content

[0006] The purpose of the utility model is to solve the existing problems of heavy weight and high cost, and inconvenience in performing convenient heat dissipation treatment on the cover.

[0007] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0008] A plastic motor cover with an integrated radiator is provided to improve the above problems.

[0009] The specific application is as follows:

[0010] It includes a plastic cover and a heat dissipation aluminum block. A metal piece is installed on the plastic cover. The heat dissipation aluminum block is installed in the metal piece. A potting glue groove is opened on the plastic cover. Connector terminals are installed on the plastic cover. A grounding terminal is bolted to the plastic cover. Bolt holes are opened on the plastic cover.

[0011] As a preferred technical solution of the present application, the connector terminals are evenly distributed on the plastic cover.

[0012] As a preferred technical solution of the present application, the inner side surface of the metal part is in contact with the outer side surface of the heat dissipation aluminum block.

[0013] As a preferred technical solution of the present application, the inner diameter of the grounding terminal is equal to the inner diameter of the bolt hole.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In the scheme of this application:

[0016] 1. Through the plastic cover, the metal block that provides heat dissipation for the PCBA board is integrally formed with the main body of the plastic cover. The metal block is crucial for dissipating heat from key electronic components on the PCBA board, preventing them from burning out due to high temperature operation. The grounding terminals and connector terminals are all integrally formed on the plastic cover, simultaneously solving the problem of signal and charge conduction inside and outside the cover. The one-piece plastic cover eliminates the secondary processing of the original all-aluminum design and simplifies the process flow. The structural design of the metal part reserves a potting glue groove, which can be filled with potting glue when necessary, helping to improve the sealing effect. The edge of the plastic cover is chamfered to fit the motor housing, which helps to improve the sealing effect. The edge of the cover protrudes from the motor housing, which also helps to improve the sealing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Example 1:

[0027] like Figure 1-3 As shown, this embodiment proposes a plastic motor cover with an integrally formed radiator, comprising a plastic cover 1 and a heat dissipation aluminum block 2, a metal part 6 being mounted on the plastic cover 1, the heat dissipation aluminum block 2 being mounted inside the metal part 6, a potting glue groove 3 being provided on the plastic cover 1, a connector terminal 4 being mounted on the plastic cover 1, a grounding terminal 5 being bolted to the plastic cover 1, and a bolt hole 7 being provided on the plastic cover 1.

[0028] Example 2:

[0029] The solution in Example 1 is further introduced below in conjunction with a specific working method, as described below:

[0030] like Figure 3 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, the connector terminals 4 are evenly distributed on the plastic cover 1, which can ensure that the multiple connector terminals 4 can be connected and used smoothly.

[0031] like Figure 1As shown, as a preferred embodiment, on the basis of the above method, further, the inner side of the metal part 6 is fitted with the outer side of the heat dissipation aluminum block 2, which can ensure that the heat dissipation aluminum block 2 in the metal part 6 can play a sufficient heat dissipation role.

[0032] like Figure 2 As shown, as a preferred embodiment, on the basis of the above method, further, the inner diameter of the grounding terminal 5 is equal to the inner diameter of the bolt hole 7, which can ensure that when the bolt is used to pass through the bolt hole 7 and connect with the grounding terminal 5, it can avoid affecting the grounding terminal 5.

[0033] Specifically, when using the plastic motor cover with the radiator integrally formed: Figure 1-3 The main body of the cover is made of plastic, and the metal block that provides heat dissipation for the PCBA board is integrally formed with the main body of the plastic cover 1; the metal block is crucial for the heat dissipation of key electronic components on the PCBA board to prevent them from being burned out due to working at high temperatures. The grounding terminal 5 and the connector terminal 4 are all integrally formed on the plastic cover 1, while solving the signal and charge conduction problems inside and outside the plastic cover 1. The integrally formed plastic cover 1 can eliminate the secondary processing process of the original all-aluminum design, simplify the process flow, replace aluminum with plastic, reduce product weight, and at the same time install the heat dissipation aluminum block 2 in the plastic cover 1.

[0034] The metal part 6 has a structural design with a reserved potting glue groove 3, which can be filled with potting glue when necessary, which helps to improve the sealing effect. The edge of the plastic cover 1 is chamfered to fit the motor housing, which helps to improve the sealing effect. The edge of the cover extends beyond the motor housing, which helps to improve the sealing effect.
