Description

Technical Field

[0001] This utility model relates to the field of motor housing technology, and in particular to a split extruded aluminum heat dissipation housing structure for an internal rotary motor. Background Technology

[0002] An internal rotor motor is a type of motor driven by the rotation of an internal rotor. Its stator is fixed on the outside, while the rotor is located inside and rotates with the main shaft. This structure features high speed and high efficiency and is commonly found in new energy vehicles, industrial equipment, and home appliances. An internal rotor motor consists of a stator and a rotor. The stator is usually fixed inside the motor housing, while the rotor is located inside the stator and rotates with the main shaft.

[0003] In existing large-diameter motor housings, the heat dissipation shell and mounting base are mostly integrally molded during production. During motor installation, the mounting base directly connects to the external frame. However, this integral structure requires complete replacement if the base or housing is damaged during installation, making disassembly and repair of the internal stator and rotor structures inconvenient. Furthermore, the integrally molded heat dissipation shell makes it difficult to replace individual sections or parts when corrosion or damage occurs; the entire heat dissipation shell must be replaced. Additionally, existing large-tonnage aluminum extrusion equipment is too expensive and has a high scrap rate for large-diameter motor housing production, while conventional machining processes are cumbersome, wasteful of materials, and time-consuming. Dividing the large-diameter motor housing into multiple smaller shells for separate processing allows for the use of small-tonnage aluminum extrusion equipment. This combination of small-tonnage aluminum extrusion equipment and conventional machining processes can reduce costs for this component. Therefore, we propose a separate extruded aluminum heat dissipation shell structure for internal rotating motors to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the prior art by proposing a split extruded aluminum heat dissipation shell structure for an internal rotating motor.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a split extruded aluminum heat dissipation shell structure for an internal rotary motor, comprising a heat dissipation shell, a base, a small shell, a slot, a strip, a threaded hole, a through hole, and a locking screw. The heat dissipation shell is composed of multiple small shells. Each small shell has a slot at one end and a strip at the other end. The strips are movably installed into adjacent slots. Each small shell has a threaded hole fixedly installed on one side. The base has multiple through holes fixedly installed on its edge. Locking screws are threaded into the threaded holes and through holes.

[0006] Furthermore, the small outer shell is arranged in a circular structure, and the card strip and the inside of the card slot are connected by a snap-fit.

[0007] Furthermore, the threaded holes and through holes are all in one-to-one correspondence.

[0008] Furthermore, the heat dissipation housing and the base are fitted with an interference fit.

[0009] Compared with the prior art, this utility model has the following advantages:

[0010] (1) By sequentially installing the clips on the small outer shell into the adjacent slots, the small outer shells can be sequentially arranged in a circular pattern to form a heat dissipation shell, thus making the heat dissipation shell a split structure, which is easy to disassemble and install. When the heat dissipation shell is damaged, it is easy to replace one or several small outer shells separately. At the same time, when processing the heat dissipation shell, the heat dissipation shell can be divided into multiple small outer shells for split processing and then combined. This allows for processing using small-tonnage extrusion aluminum equipment, which is more convenient and can reduce scrap rate and material production consumption.

[0011] (2) By tightening the locking screws into the through hole and the threaded hole in sequence, the base can be locked into the heat dissipation shell. At the same time, the small shell can be limited in the axial direction. The base and the heat dissipation shell are separate structures, so when the base or the heat dissipation shell is damaged, it is not necessary to replace the whole structure. At the same time, it is convenient to replace a damaged part, which improves maintenance efficiency. Attached Figure Description

[0017] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0018] like Figure 1-4 The diagram shows a split extruded aluminum heat dissipation housing structure for an internal rotary motor, comprising a heat dissipation housing 1, a base 2, a small housing 3, a slot 4, a retaining strip 5, a threaded hole 6, a through hole 7, and a locking screw 8. The heat dissipation housing 1 is composed of multiple small housings 3. Each small housing 3 has a slot 4 at one end and a retaining strip 5 at the other end. The retaining strips 5 are movably installed into the adjacent slots 4. Each small housing 3 has a threaded hole 6 fixedly installed on one side. Each base 2 has multiple through holes 7 fixedly installed on its edge. Locking screws 8 are threaded into the threaded holes 6 and through holes 7.

[0019] In this embodiment, the small outer shells 3 are arranged in a circular structure, and the clips 5 are connected to the slots 4 by snap-fit. By sequentially installing the clips 5 on the small outer shells 3 into adjacent slots 4, the small outer shells 3 can be sequentially arranged in a circular pattern to form the heat dissipation shell 1. This makes the heat dissipation shell 1 a modular structure, facilitating disassembly and installation. When the heat dissipation shell 1 is damaged, it is easy to replace one or more small outer shells 3 individually. Furthermore, during the processing of the heat dissipation shell 1, it can be divided into multiple small outer shells 3 for processing and then combined. This allows for processing using low-tonnage aluminum extrusion equipment, making it more convenient and reducing scrap rates and material consumption. (Note: The number of small outer shells can be adjusted according to the diameter of the heat dissipation shell; the larger the diameter, the more small outer shells are needed.)

[0020] In this embodiment, the threaded hole 6 and the through hole 7 are one-to-one; by tightening the locking screw 8 into the through hole 7 and the threaded hole 6 in sequence, the base 2 can be locked into the heat dissipation shell 1, and at the same time, the small shell 3 can be limited in the axial direction. The base 2 and the heat dissipation shell 1 are separate structures, so when the base 2 or the heat dissipation shell 1 is damaged, it is not necessary to replace the whole structure. At the same time, it is convenient to replace the damaged part, which improves the maintenance efficiency.

[0021] In this embodiment, by using an interference fit between the heat dissipation shell 1 and the base 2, the concentricity between the heat dissipation shell 1 and the base 2 can be guaranteed.

[0022] The working principle of the split extruded aluminum heat dissipation shell structure for an internal rotary motor mentioned in this utility model is as follows:

[0023] In use, by sequentially installing the clips 5 on the small outer shell 3 into the adjacent slots 4, the small outer shells 3 can be sequentially arranged in a circular pattern to form the heat dissipation shell 1. This makes the heat dissipation shell 1 a modular structure, which is easy to disassemble and install. When the heat dissipation shell 1 is damaged, it is easy to replace one or more small outer shells 3 individually. At the same time, when processing the heat dissipation shell 1, it can be divided into multiple small outer shells 3 for processing and then combined. This allows for processing using small-tonnage aluminum extrusion equipment, which is more convenient and can reduce scrap rate and material production consumption.

[0024] Meanwhile, by tightening the locking screws 8 into the through hole 7 and the threaded hole 6 in sequence, the base 2 can be locked into the heat dissipation shell 1. At the same time, the small shell 3 can be limited in the axial direction. Since the base 2 and the heat dissipation shell 1 are separate structures, when the base 2 or the heat dissipation shell 1 is damaged, it is not necessary to replace the whole structure. At the same time, it is convenient to replace the damaged part, which improves maintenance efficiency.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
