Description

Technical Field

[0001] This utility model relates to the field of inverter housing structure, and in particular to a cap-type inverter housing. Background Technology

[0002] In the field of industrial automation control, traditional drive systems typically consist of three main parts: the motor, the frequency converter, and the control cabinet, all installed separately. This separate installation method occupies a large amount of on-site space, requires complex cabling connections, and is not only costly but also increases system complexity, causing inconvenience for customers. It usually requires professional personnel to provide on-site commissioning and adaptation services.

[0003] Currently, a few products have attempted to integrate the motor and frequency converter into one unit, but these are merely simple cases where the frequency converter is mounted on or placed directly above the motor, failing to integrate the relevant functions of the control cabinet. While this simple combination reduces some cabling, it still relies on an external control cabinet and cannot achieve complete integration.

[0004] Even when some products attempt to combine the three functions, they fail to achieve reasonable sharing and utilization of space. This lack of overall planning results in a bulky product appearance, uncoordinated structure, and an inability to truly reduce costs and improve integration.

[0005] In addition, the internal space planning of existing products is unreasonable, with different functional modules mixed together, which not only fails to effectively solve the electromagnetic interference problem, but also increases the difficulty of maintenance. Utility Model Content

[0006] The purpose of this utility model is to provide a cap-type inverter housing to solve the technical problems of low integration, low space utilization, and unreasonable internal layout in the existing cap-type inverter.

[0007] To solve the above-mentioned technical problems, this utility model provides a cap-type inverter housing, which is fitted onto the motor of the cap-type inverter;

[0008] Multiple independent spatial regions are formed between the housing and the motor, including a first region, a second region, a third region, and a fourth region;

[0009] The first area is used to install the frequency conversion component of the hat-shaped frequency converter;

[0010] The second area is used to install the heat dissipation components of the cap-type frequency converter, forming a heat dissipation space, and is located above the motor;

[0011] The third area is used to install the control components of the cap-type frequency converter;

[0015] Furthermore, the front cover assembly includes a front cover body and a front cover panel;

[0016] The front cover body is a rectangular frame with a display window frame in the middle. The display window frame has a rectangular opening in the middle and multiple button holes at the bottom of the rectangular opening. The rectangular opening is used to install the display screen, and the multiple button holes are used to install operation buttons. The front cover panel is mounted on the display window frame.

[0017] Furthermore, the first region is located at the upper front part of the main housing and at the rear side of the front cover body; the second region is located at the middle part of the main housing; the third region is located at the upper rear part of the main housing; and the fourth region is located at the lower rear part of the main housing and below the third region.

[0018] Furthermore, a first partition is provided at the junction of the first region and the second region, and a second partition is provided at the junction of the second region and the third region.

[0021] Furthermore, the rear side of the main housing is provided with a plurality of cable fasteners, which are located on both sides of the fourth region.

[0022] Furthermore, the number of cable fasteners provided on each side of the fourth region is 2-4.

[0023] Furthermore, a heat dissipation grille is provided on the upper side of the main housing, and the heat dissipation grille is located above the second region.

[0024] Compared with the prior art, the present invention has at least the following beneficial effects:

[0025] The cap-shaped inverter housing proposed in this utility model divides the space between the housing and the motor into multiple independent areas, achieving a reasonable partitioned layout of the frequency conversion components, heat dissipation components, and control components. This not only ensures the rational allocation and isolation of each functional module but also solves the problem of electromagnetic interference.

[0033] Based on the teachings of this specification, those skilled in the art can form new technical solutions by combining different implementation methods without creating technical contradictions. Such variations should be considered to fall within the protection scope of this patent.

[0034] The following is a more detailed description of a cap-type frequency converter housing according to the present invention, with reference to the schematic diagrams, which illustrate preferred embodiments of the present invention. It should be understood that those skilled in the art can modify the present invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the present invention.

[0035] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0036] like Figures 1 to 5 As shown in the figure, this utility model embodiment proposes a cap-type inverter housing, which is fitted onto the motor of the cap-type inverter.

[0037] Multiple independent spatial regions are formed between the housing and the motor, including a first region 10, a second region 11, a third region 12, and a fourth region 13. The first region 10 is used to install the frequency conversion component of the cap-type frequency converter; the second region 11 is used to install the heat dissipation component of the cap-type frequency converter, forming a heat dissipation space, and is located above the motor; the third region 12 is used to install the control component of the cap-type frequency converter; and the fourth region 13 forms a spare installation space.

[0038] The cap-shaped inverter housing is divided into spatial zones, placing the frequency conversion component, heat dissipation component, and control component in separate independent spaces. This effectively isolates electromagnetic interference between the components while providing suitable installation space and heat dissipation environment for each component. The fourth zone 13 serves as a spare installation space, allowing for the flexible installation of additional functional modules according to actual needs.

[0039] In this embodiment, as Figure 2 As shown, the outer casing includes a main housing 1, a front cover assembly, a rear upper cover 4, and a rear lower cover 5.

[0040] The lower side of the main housing 1 is provided with a connecting structure, and the main housing 1 is sleeved on the motor through the connecting structure; the front cover assembly is installed on the front side of the upper part of the main housing 1, the rear upper cover 4 is installed on the upper part of the rear side of the main housing 1; the rear lower cover 5 is installed on the lower part of the rear side of the main housing 1 and is located below the rear upper cover 4.

[0041] The front cover assembly, the upper rear cover 4, and the lower rear cover 5 are detachably mounted on the main housing 1, which facilitates the installation of the frequency converter assembly, the heat dissipation assembly, and the control assembly, as well as maintenance and repair.

[0042] Furthermore, the front cover assembly includes a front cover body 2 and a front cover panel 3.

[0043] The front cover body 2 is a rectangular frame with a display window frame in the middle. The display window frame has a rectangular opening in the middle, and multiple button holes are located at the bottom of the rectangular opening. The rectangular opening is used to mount the display screen, providing users with intuitive system status information and parameter displays. The multiple button holes are used to mount operation buttons, which are logically arranged for easy operation and parameter settings. The front cover panel 3 is mounted on the display window frame to prevent dust and moisture from entering the interior.

[0044] In this embodiment, as Figure 5 As shown, the first region 10 is located at the upper front part of the main housing 1 and at the rear side of the front cover body 2; the second region 11 is located at the middle part of the main housing 1; the third region 12 is located at the upper rear part of the main housing 1; and the fourth region 13 is located at the lower rear part of the main housing 1, below the third region 12, and to the right of the motor.

[0045] The frequency converter is placed in the first area 10, close to the operating interface, to reduce signal transmission distance and facilitate connection with the interface. The second area 11, located at the center of the structure, houses the heat dissipation components, providing balanced heat dissipation for all areas and creating effective heat conduction and convection channels. The control components are located in the third area 12, away from heat sources to reduce thermal interference, and at a suitable distance from the wiring port 8 to facilitate the introduction and output of control signals, thereby effectively reducing electromagnetic interference. A spare installation space is provided in the fourth area 13, close to the wiring area, facilitating cable connections when adding functional modules without affecting the operation of the main functional components.

[0046] Furthermore, the width of the third region is greater than the width of the fourth region, so that a cable channel space is formed on the left and right sides of the fourth region directly below the third region. This allows multiple cables to enter the equipment from the cable channels on the left and right sides, effectively avoiding electromagnetic interference problems that may be caused by cross-arranged cables.

[0047] In this embodiment, a first partition 6 is provided at the junction of the first region 10 and the second region 11, and a second partition 7 is provided at the junction of the second region 11 and the third region 12. The first partition 6 and the second partition 7 are fixedly connected to the inner wall of the main housing 1.

[0048] The first partition 6 and the second partition 7 further enhance the physical isolation between functional areas, reduce heat conduction between different areas, and improve the electromagnetic shielding effect. The first partition 6 and the second partition 7 also improve the rigidity of the overall structure, giving the shell better vibration and impact resistance.

[0049] In this embodiment, both the first partition 6 and the second partition 7 are provided with multiple ventilation holes. The ventilation holes allow air to circulate moderately between the areas while maintaining physical isolation between the areas, forming a more efficient internal air circulation system, thereby improving the overall heat dissipation efficiency.

[0050] In this embodiment, a wiring port 8 is provided on the lower rear side of the main housing 1. The wiring port 8 is located below the third region 12 and on both sides of the fourth region 13, that is, in the part where the third region is wider than the fourth region. The layout of the wiring port 8 facilitates the connection of various cables, making wiring operations more convenient, while also reducing cable bending and stretching, and lowering the risk of cable damage.

[0051] Furthermore, the rear side of the main housing 1 is provided with multiple cable fasteners 9, which are located on both sides of the fourth region 13. The cable fasteners 9 are used to organize and manage cables, making the wiring area neat and orderly, and facilitating later maintenance, inspection, and cable replacement.

[0052] The fourth region 13 has 2-4 cable fasteners 9 on each side, which can meet the cable organization and management needs of most application scenarios. Preferably, there are 3 cable fasteners 9 on each side.

[0053] In this embodiment, a heat dissipation grille 14 is provided on the upper side of the main housing 1, and the heat dissipation grille 14 is located above the second region 11. The heat dissipation grille 14 provides a heat dissipation channel, through which hot air inside the main housing 1 is discharged, improving heat dissipation efficiency and thus effectively reducing the operating temperature of the internal components.

[0054] In summary, the cap-shaped inverter housing proposed in this utility model achieves a reasonable partitioned layout of the frequency conversion components, heat dissipation components, and control components by dividing the space between the housing and the motor into multiple independent areas. This not only ensures the rational allocation and isolation of each functional module but also solves the electromagnetic interference problem. Furthermore, the cap-shaped design allows the housing to fit tightly onto the motor, forming an integrated structure, reducing the space occupied by the equipment and simplifying the installation process.

[0055] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
