A motor controller housing structure

Abstract

This application provides a motor controller enclosure structure, including an enclosure body with heat dissipation vents on both sides and a heat dissipation structure on one side of the enclosure body. The heat dissipation structure includes two first L-shaped limiting plates fixedly installed on one of the enclosure bodies. A plurality of connecting frames are interleaved between the two first L-shaped limiting plates, stacked sequentially from top to bottom. Each connecting frame has a cooling fan connected to its side away from the enclosure body. This application utilizes the first L-shaped limiting plates and connecting frames. Since the cooling fan is mounted on the connecting frames and its installation is limited by the insertion of the connecting frames into the first L-shaped limiting plates, the traditional method of using multiple bolts for fixing is eliminated. This eliminates the need for cumbersome bolt disassembly and reassembly operations when cleaning or repairing the cooling fan.

Description

Technical Field

[0001] This utility model relates to the field of motor controller enclosure technology, and more specifically, to a motor controller enclosure structure. Background Technology

[0002] During the operation of the motor controller, the internal electronic components generate a lot of heat. If the heat cannot be dissipated in a timely and effective manner, it will seriously affect the performance and service life of the motor controller, and may even lead to component damage. Therefore, heat dissipation design is a crucial part of the motor controller enclosure structure design.

[0003] Currently, the common heat dissipation method in existing technologies is to install a cooling fan on the motor controller housing. The cooling fan accelerates airflow and dissipates heat from inside the housing. However, most existing cooling fan installation methods use multiple bolts (usually four bolts) for fixing. While this method ensures the stability of the cooling fan installation, it has significant drawbacks in practical applications: when cleaning or repairing the cooling fan, multiple bolts need to be removed and installed sequentially, which is cumbersome and time-consuming. Therefore, we propose an improvement to this, suggesting a new motor controller housing structure. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In the scheme of this application:

[0016] This application uses a first L-shaped limiting plate and a connecting frame. Since the cooling fan is installed on the connecting frame and the connecting frame is plugged into the first L-shaped limiting plate, the installation of the cooling fan is limited.

When the cooling fan needs to be cleaned or repaired, there is no need to perform cumbersome bolt disassembly and assembly operations. The cooling fan can be disassembled and installed simply by plugging and unplugging, saving maintenance time. Attached Figure Description

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] For an example, please refer to... Figures 1-5 A motor controller enclosure structure includes an enclosure body 1, with heat dissipation vents 101 on both sides of the enclosure body 1. A heat dissipation structure is provided on one side of the enclosure body 1, comprising two first L-shaped limiting plates 2 fixedly installed on one of the enclosure bodies 1. A plurality of connecting frames 201 are interleaved between the two first L-shaped limiting plates 2, stacked sequentially from top to bottom. Each connecting frame 201 has a cooling fan 202 connected to its side away from the enclosure body 1. Since the cooling fan 202 is installed on the connecting frame 201 and its installation is limited by the insertion of the connecting frame 201 into the first L-shaped limiting plate 2, this insertion method eliminates the need for the traditional method of using multiple bolts for fixing. When cleaning or repairing the cooling fan 202, there is no need for cumbersome bolt disassembly and assembly operations; the cooling fan 202 can be disassembled and installed simply by plugging and unplugging, saving maintenance time.

[0028] Furthermore, support plates 4 are fixedly installed on both sides of the main body 1 of the enclosure. One of the support plates 4 contacts the bottom of the cooling fan 202 and the connecting frame 201 located at the bottom. The support plate 4 can support the cooling fan 202.

[0029] Furthermore, dust filter structures are provided on both sides of the main body 1, and the heat dissipation structure is located inside one of the dust filter structures. The dust filter structures can reduce the amount of dust entering the main body 1 during use.

[0030] Furthermore, the dust filtration structure includes a connector installed on the side of the main body 1 of the housing. The connector is detachably connected to a protective cover 301, and a dust filter 303 is provided on the protective cover 301. The protective cover 301 can support the dust filter 303, and the dust filter 303 can reduce the amount of dust entering the main body 1 of the housing. In addition, the protective cover 301, which corresponds to the position of the cooling fan 202, can also protect the cooling fan 202.

[0031] Furthermore, the connector includes two second L-shaped limiting plates 3 fixedly installed on the side of the main body 1 of the housing. Two insert plates 302 are interposed between the two second L-shaped limiting plates 3, and the two insert plates 302 are fixedly installed on both sides of the protective cover 301. The protective cover 301 can be installed by inserting the insert plates 302 into the second L-shaped limiting plates 3.

[0032] Furthermore, the bottom of the protective cover 301 is open, and the support plate 4 blocks the opening at the bottom of the protective cover 301, and the support plate 4 can also support the protective cover 301.

[0033] Furthermore, the cooling fan 202 is located inside the protective cover 301 of one of the dust filter structures, so that the cooling fan 202 can be protected by the corresponding protective cover 301.

[0034] Furthermore, a limiting component is provided on the top of the main body 1 of the housing. The limiting component is used to limit the protective cover 301 to improve the stability of the protective cover 301.

[0035] Furthermore, the limiting component includes a damping shaft 5 installed on the top of the housing body 1. The top end of the damping shaft 5 is connected to a baffle 501, and the bottom of the baffle 501 contacts the top of the protective cover 301. The baffle 501 can limit the protective cover 301. The damping shaft 5 has a preset damping force, so that the baffle 501 can remain stationary after rotation.

[0036] Furthermore, a door 102 is installed on the front of the main body 1 of the enclosure via a hinge, and a lock is provided between the door 102 and the main body 1 of the enclosure. The lock and the cooling fan 202 are existing components, and their specific structures and operating principles are existing technologies, which will not be described in detail in this application.

[0037] The usage process of the motor controller housing structure provided by this utility model is as follows:

[0038] When it is necessary to clean the dust filter 303 and the cooling fan 202, rotate the baffle 501 to separate the baffle 501 from the insert plate 302, and pull the protective cover 301 upward to separate the insert plate 302 from the second L-shaped limiting plate 3. Then the dust filter 303, the protective cover 301, and the insert plate 302 can be removed. Then push the cooling fan 202 upward to separate the connecting frame 201 from the first L-shaped limiting plate 2. Then the cooling fan 202 can be removed and the cooling fan 202 and the dust filter 303 can be cleaned. After cleaning, insert the connecting frame 201 and the first L-shaped limiting plate 2 together, and then insert the insert plate 302 and the second L-shaped limiting plate 3 together. Then rotate the baffle 501 to contact the top of the protective cover 301.
