Description

Technical Field

[0001] The utility model relates to the technical field of speed regulators, in particular to a housing for a speed regulator and a speed regulator used for a power supply. Background Art

[0002] Speed ​​regulators, as used in motors, convert industrial frequency power to AC power of varying frequencies to achieve variable speed operation. Widely used in industry and automation, they adjust and control motor speed to achieve energy savings, improve production efficiency, and optimize processes. However, the heat generated by speed regulators during prolonged, high-load operation is a significant issue, especially in high-temperature and harsh environments.

[0003] Currently, speed regulator heat dissipation primarily relies on vents and fans. Specifically, vents dissipate internal heat to the outside through air convection, while fans accelerate heat transfer by forced airflow. However, this traditional heat dissipation method has significant drawbacks. For example, under continuous high-load operation, particularly in high temperatures or harsh environments, the heat generated by the speed regulator is difficult to dissipate promptly and effectively. Furthermore, the limited natural convection capacity of the vents can easily lead to localized overheating within the speed regulator.

[0004] In harsh environments, dust, moisture, corrosive gases, and other factors can easily enter the speed controller through the heat dissipation holes, damaging the electronic components, affecting normal operation, and even shortening its service life. In particular, the arrangement and layout of the speed controller's internal components can affect heat dissipation. An improperly designed internal structure can easily concentrate heat in a localized area, making it difficult to dissipate evenly, which can accelerate component aging and damage.

[0005] As a result, traditional heat dissipation structures are insufficient for the high-intensity use of speed regulators, easily causing damage to the equipment or shortening its service life. With the expansion of speed regulator applications in the industrial field and the increasing complexity of working environments, relying solely on heat dissipation holes and fans can no longer meet actual needs.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the present invention.

[0029] Example

[0030] Combine Figures 1 to 5 , this embodiment provides a housing for a speed regulator, comprising a housing 1. The housing 1 is constructed by a first shell member 2 and a second shell member 3 that are buckled together front to back. The first shell member 2 is a drawer-like structure, which is provided with a front side panel 4 and a lower bottom panel 5. The second shell member 3 is a cover plate structure, which is provided with a rear side panel 6 and an upper top panel 7. A partition member 8 is also provided in the housing 1, and the rear side panel 6 is provided with a window 9 for facilitating the installation and positioning of the partition member 8, and the partition member 8 can be detachably placed flat between the upper top panel 7 and the lower bottom panel 5 to define an installation space above and a separation space below.

[0031] In the above, the first shell part 2 and the second shell part 3 are connected to each other front and back to form a modular structural combination, and the first shell part 2 is a drawer-like structure, which is convenient for users to maintain and repair the internal equipment from the front, and the second shell part 3 is a cover structure that can be easily disassembled, which not only improves the convenience of equipment maintenance, reduces the complexity of equipment disassembly and assembly, but also facilitates the independent replacement of heat dissipation components and electrical components.

[0032] A detachable partition 8 is provided in the box body 1, which divides the internal space into an upper installation space and a lower separation space. The upper space can be used to install the main components of the speed regulator, while the lower separation space can isolate some electrical components or allow wiring layout, etc., effectively avoiding the uneven heat dissipation problem caused by unreasonable layout of internal components of the equipment, and helping to improve the overall heat dissipation effect of the speed regulator.

[0033] The partition member 8 is installed and limited on the window 9 of the rear side plate 6, and can be installed stably and limited between the upper top plate 7 and the lower bottom plate, thereby increasing the stability of the partition and avoiding the displacement of the partition due to vibration or other external forces during long-term use. It not only helps to maintain the fixed layout of internal components, but also improves the impact resistance of the speed regulator and enhances the reliability of the equipment in complex environments.

[0034] Preferably, the partition member 8 is a rectangular plate, and a limiting ridge 10 is provided at its end to allow the partition member 8 to be snapped onto the window 9. By providing the limiting ridge 10 at the end of the partition member 8, the partition member 8 can be firmly snapped onto the window 9 of the rear side panel 6, preventing the partition member from moving or displacing due to vibration or external force during operation of the equipment, thereby ensuring the stability of the partition member 8 during long-term use.

[0035] like Figure 2 and Figure 3 As shown, in this embodiment, the first shell member 2 and the second shell member 3 are each equipped with a left side panel 11 and a right side panel 12, and the side panels on the same side are fitted with guide rails to cooperate to construct an entire side surface. On the one hand, by designing a guide rail for sliding fit between the left and right side panels 12, the user can easily slide and assemble or disassemble the first shell member 2 and the second shell member 3. On the other hand, the sliding fit structure between the left and right side panels 12 ensures that the two shell members are tightly combined, enhancing the stability and impact resistance of the entire shell. In addition, the guide rail sliding fit method allows the first shell member 2 and the second shell member 3 to form an integral side structure after assembly, without protruding fixings or seams.

[0036] In this embodiment, the two side panels of the first housing member 2 are correspondingly provided with insertion rails 13. The partition member 8 is mounted at the window 9 via a limiting ridge 10 and is driven by the second housing member 3 to slide synchronously into the insertion rails 13. By providing the insertion rails 13 on the side panels of the first housing member 2 and allowing the partition member 8 to slide synchronously with the second housing member 3 into the insertion rails 13, the assembly convenience, structural stability, and heat dissipation performance of the speed regulator housing are significantly improved, ensuring safe and stable operation of the equipment under various complex operating conditions while also meeting the needs of large-scale production.

[0037] It's worth noting that the height of the separating space is comparable to the thickness of partition member 8, allowing partition member 8 to remain roughly suspended within housing 1. This maintains a defined airflow path between the upper and lower spaces, facilitating air circulation within the device and preventing heat buildup that could result from partition member 8 abutting the walls of housing 1. Furthermore, air can flow freely between the upper and lower spaces, dissipating heat generated within the device, thereby enhancing the speed regulator's heat dissipation, effectively lowering the device's operating temperature and preventing malfunctions or damage due to overheating.

[0038] like Figure 4As shown, in this embodiment, the front side plate 4 of the first shell member 2 is provided with at least an assembly hole 14, a motor plug interface 15, and a heat dissipation hole 16. The assembly hole 14 and the motor plug interface 15 are located in the installation space respectively, and the heat dissipation hole 16 is located at the junction of the installation space and the separation space. The installation space is used to compactly arrange various components, and the separation space is connected to the installation space for wiring layout. Therefore, the assembly hole 14 and the motor plug interface 15 are located in the installation space, which facilitates the stable installation and wiring operation of the motor and internal components, and the heat dissipation hole 16 is located at the junction of the installation space and the separation space, ensuring the smooth flow of the heat dissipation airflow, and improving the overall integration of the speed regulator with a precise functional layout, making the internal space utilization of the equipment more efficient and reasonable.

[0039] Furthermore, the front side panel 4 of the first housing member 2 extends outwardly with a flange structure for installation in an external environment. The extended flange provides a more stable installation of the housing, preventing loosening or displacement caused by vibration or other external factors, and ensuring stability and safety during long-term operation.

[0040] The second housing member 3 is provided with a plurality of ribs 17 facing the first housing member 2, and the first housing member 2 is provided with corresponding grooves (not shown) that engage with the ribs 17. Thus, the male-female plug-in fit between the ribs 17 and the grooves further enhances the secure assembly and disassembly connection between the first and second housing members 2 and 3.

[0041] In addition, this embodiment provides a speed regulator for a power supply, including a housing for the speed regulator as described above. This speed regulator can be widely used in a variety of motor equipment and can be rapidly promoted, suitable for different types of motor speed control. The housing described above not only improves the heat dissipation, installation stability, and maintenance convenience of the speed regulator, but also enhances the reliability, safety, and adaptability of the motor speed regulation function. It is suitable for various complex industrial environments, can provide efficient and stable motor speed regulation services, and has broad application prospects in the field of motor control.

[0042] The above are only preferred implementations of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention fall within the protection scope of the present invention.
