Description

Technical Field

[0001] This utility model relates to the field of power controller technology, specifically a power controller that is easy to maintain. Background Technology

[0002] With the development of computer network technology, the demand for servers, communication program-controlled switches and various electronic devices is increasing. As a result, the requirements for the environment in which the equipment is located (such as computer rooms, cabinets, etc.) are also increasing. All facilities involved in the operation of critical equipment must have high reliability and availability, especially for power distribution and management devices that connect electrical equipment. There is a need for a power controller that is easy to maintain.

[0003] Existing power controllers are not stable or reliable enough, or lack sufficient protection functions, which may lead to the destruction of expensive equipment or even the collapse of the entire system. In addition, existing power controllers have other shortcomings. Power controllers have high requirements for cable stability during use. Existing power controllers usually do not have cable loosening prevention functions, which makes it difficult to reliably plug the cable into the internal terminal. This can easily lead to poor contact of the controller housing due to cable loosening during use. The internal temperature of the power controller will continue to rise during use. Existing power controllers do not have good overheat protection performance, which can easily lead to damage to the controller housing due to overheating. Power controllers require regular inspection and maintenance. Existing power controllers are usually inconvenient to inspect and maintain. This makes it difficult for users to remove the cover from the surface of the controller housing to inspect and maintain the internal components, thus shortening the lifespan of the power controller.

[0009] Preferably, a heat dissipation frame is installed on the surface of the controller housing, a heat-conducting plate for heat conduction is installed inside the heat dissipation frame, a dust-proof net for blocking dust in the air is provided on the surface of the heat dissipation frame, fixing blocks are installed on both sides of the dust-proof net, and anti-detachment clips are installed on the surface of the fixing blocks, and the anti-detachment clips are engaged with the inner wall of the heat dissipation frame.

[0010] Preferably, the interior of each heat dissipation frame is fitted with heat dissipation fins for rapid heat dissipation of the controller housing by screws. Both the heat dissipation frame and the inner wall of the controller housing are provided with equally spaced heat dissipation through holes, which are connected to the interior of the controller housing and the heat dissipation frame, respectively.

[0011] Preferably, the easy-maintenance component is disposed on the inner wall of the controller housing and the surface of the cover.

[0012] Preferably, each of the arc-shaped clips is equipped with a tension spring, one end of which is fixed to the inner wall of the clip body. Each of the two sides of the cover is equipped with a mounting block, and the mounting block is threaded with a mounting stud.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This easy-to-maintain power controller not only allows the power controller to be stably plugged into the wiring port during use, avoiding poor contact of the controller housing due to loose wires during use, but also allows the power controller to quickly dissipate heat inside the controller housing, preventing damage to the controller housing due to overheating. Furthermore, it makes it convenient for users to remove the cover from the surface of the controller housing for inspection and maintenance of the internal components, thus extending the service life of the power controller.

[0014] 1. By incorporating a high-stability mechanism, the sealing gasket moves under the combined action of the sealing spring and sealing airbag within the high-stability assembly. This allows the sealing gasket to slide within the guide groove, which guides the gasket. The sealing spring and sealing airbag then move the gasket until it contacts the surface of the wire. Under the combined action of the sealing frame and the sealing gasket, the wire is clamped and fixed to the surface of the connector, preventing the wire from detaching from the connector during power controller use. This achieves the power controller's anti-loosening function, ensuring that the wire is stably plugged into the connector during power controller use, preventing poor contact of the controller housing due to wire detachment.

[0015] 2. By incorporating an overheat protection mechanism, the internal temperature of the controller housing will continuously rise after prolonged operation. The user controls the heat dissipation fins inside the heat sink frame to operate. Under the combined action of the heat dissipation fins and the heat conduction plate, the heat inside the controller housing is drawn into the heat sink frame through the heat dissipation holes. The dust filter filters dust and impurities in the air. Subsequently, the user pulls the dust filter, causing it to move away from the anti-detachment clip from the inside of the heat sink frame, thereby removing the dust filter from the surface of the heat sink frame for cleaning. This achieves the overheat protection function of the power controller, enabling the power controller to quickly dissipate the heat inside the controller housing during use, preventing damage to the controller housing due to overheating.

[0016] 3. By incorporating a convenient maintenance mechanism, the user can loosen the mounting studs on the mounting block surface and then pull the cover upwards. As the cover moves away from the inside of the controller housing, the cover moves the rubber pad away from the inside of the controller housing, causing the locking mechanism to move away from the inside of the controller housing. At this point, under the elastic force of the extension spring, the arc-shaped locking mechanism moves away from the inner wall of the controller housing, thereby removing the cover from the surface of the controller housing for inspection and maintenance of the internal components. This facilitates convenient maintenance of the power controller, allowing users to easily remove the cover from the surface of the controller housing for inspection and maintenance of the internal components, thus extending the service life of the power controller.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0025] The structure of the power controller provided by this utility model, which is convenient for maintenance, is as follows: Figure 1 and Figure 2As shown, the controller includes a controller housing 1. A cover 101 is provided on the surface of the controller housing 1, with one end of the cover 101 extending into the interior of the controller housing 1. A connector 102 is mounted on the surface of the controller housing 1. Each connector 102 has equally spaced wiring ports 104 on its surface. A wire 103 is provided on the surface of each wiring port 104, with one end of the wire 103 extending into the interior of the wiring port 104 and connecting to the controller housing 1. A display screen 112 is mounted on the surface of the cover 101. Heat dissipation holes 105 are provided on the surface of the cover 101, communicating with the interior of the controller housing 1. The controller housing 1 houses a processor 111 and a power storage device 106. The power storage device 106 is connected to the processor 111. The controller housing 1 houses a switching module 107 and a main chip 110. The main chip 110 is connected to the switching module 107. The controller housing 1 houses a voltage detection module 108 and a main power module 109. The main power module 109 is connected to the voltage detection module 108 and the main power module 109 is connected to the main chip 110.

[0026] Furthermore, such as Figure 2 and Figure 4 As shown, both the inner wall of the connector 104 and the surface of the cable 103 are provided with a high-stability mechanism 2. The high-stability mechanism 2 contains a sealing airbag 21, a sealing gasket 22, and a high-stability assembly 23. The high-stability assembly 23 is disposed on the inner wall of the connector 104 and the surface of the cable 103. The high-stability assembly 23 consists of a fixing ring 231, a sealing spring 232, a sealing frame 233, and a guide groove 234. The fixing ring 231 is installed on the surface of the cable 103, and the sealing frame 233 is installed on the inner wall of the fixing ring 231. The sealing frame 233 is provided with a high-stability mechanism 2. The sealing gasket 22 extends to the outside of the sealing frame 233. The inner wall of the sealing frame 233 is provided with guide grooves 234. The guide grooves 234 slide and engage with the surface of the sealing gasket 22. The surface of the sealing gasket 22 contacts the surface of the line body 103. The sealing frame 233 is equipped with equally spaced sealing airbags 21. The surface of the sealing airbags 21 is fixed to the surface of the sealing gasket 22. The sealing frame 233 is equipped with equally spaced sealing springs 232. One end of the sealing springs 232 is fixed to the surface of the sealing gasket 22.

[0027] During implementation, the sealing spring 232 and the sealing airbag 21 inside the high stability group 23 drive the sealing gasket 22 to move, causing the sealing gasket 22 to slide inside the guide groove 234. Under the action of the guide groove 234, the sealing gasket 22 is guided, so that the sealing spring 232 and the sealing airbag 21 drive the sealing gasket 22 to move until it contacts the surface of the wire 103. Under the joint action of the sealing frame 233 and the sealing gasket 22, the wire 103 is clamped and fixed to the surface of the connection port 104, which prevents the wire 103 from coming loose from the surface of the connection port 104 during the use of the power controller, thus realizing the function of the power controller to prevent the wire 103 from coming loose.

[0028] Furthermore, such as Figure 2 and Figure 5 As shown, the surface of the controller housing 1 is provided with an overheat protection mechanism 3. The overheat protection mechanism 3 includes a heat dissipation frame 31, a heat conduction plate 32, an anti-detachment clip 33, a fixing block 34, a dust filter 35, and heat dissipation fins 36. The surface of the controller housing 1 is equipped with a heat dissipation frame 31. The heat conduction plate 32 for heat conduction is installed inside the heat dissipation frame 31. The surface of the heat dissipation frame 31 is provided with a dust filter 35 for blocking dust in the air. Fixing blocks 34 are installed on both sides of the dust filter 35. Anti-detachment clips 33 are installed on the surface of the fixing blocks 34. The anti-detachment clips 33 are engaged with the inner wall of the heat dissipation frame 31. The interior of the heat dissipation frame 31 is equipped with heat dissipation fins 36 for rapid heat dissipation of the interior of the controller housing 1 by screws. The inner walls of the heat dissipation frame 31 and the controller housing 1 are provided with equally spaced heat dissipation holes, and the heat dissipation holes are respectively connected to the interior of the controller housing 1 and the heat dissipation frame 31.

[0029] In practice, after the controller housing 1 has been working for a long time, the internal temperature will continue to rise. The user controls the heat dissipation fins 36 inside the heat dissipation frame 31 to work. Under the combined action of the heat dissipation fins 36 and the heat conduction plate 32, the heat inside the controller housing 1 is drawn into the interior of the heat dissipation frame 31 through the heat dissipation holes. The dust and impurities in the air are filtered by the dust filter 35. Then, the user pulls the dust filter 35, which causes the dust filter 35 to move away from the interior of the heat dissipation frame 31 along with the anti-detachment clip 33, thereby removing the dust filter 35 from the surface of the heat dissipation frame 31 and cleaning the surface of the dust filter 35 to achieve the function of preventing overheating of the power controller.

[0030] Furthermore, such as Figure 3 and Figure 6As shown, both the inner wall of the controller housing 1 and the surface of the cover 101 are provided with a convenient maintenance mechanism 4. The convenient maintenance mechanism 4 includes a mounting block 41, a mounting stud 42, and a convenient maintenance component 43. The convenient maintenance component 43 is provided on the inner wall of the controller housing 1 and the surface of the cover 101. The convenient maintenance component 43 is composed of a rubber pad 431, a locking body 432, a tension spring 433, and an arc-shaped locking member 434. The inner wall of the cover 101 is equipped with a locking body 432, which engages with the inner wall of the controller housing 1. The inner wall of the cover 101 is also equipped with a rubber pad for sealing between the controller housing 1 and the cover 101. The surface of the rubber pad 431 contacts the inner wall of the controller housing 1. The surface of the clip body 432 is provided with arc-shaped clips 434. The arc-shaped clips 434 slide and engage with the inner wall of the clip body 432. The arc-shaped clips 434 engage with the inner wall of the controller housing 1. The surface of the arc-shaped clips 434 is provided with extension springs 433. One end of the extension springs 433 is fixed to the inner wall of the clip body 432. The surfaces of both sides of the cover 101 are provided with mounting blocks 41. The surface of the mounting blocks 41 is threaded with mounting studs 42. One end of the mounting studs 42 passes through the mounting blocks 41 and is threadedly fastened to the surface of the controller housing 1.

[0031] In practice, when any component inside the controller housing 1 is damaged, the inside of the controller housing 1 needs to be repaired. The user loosens the mounting studs 42 on the surface of the mounting block 41, and then pulls the cover 101 upwards. When the cover 101 moves away from the inside of the controller housing 1, the cover 101 moves the rubber pad 431 away from the inside of the controller housing 1, and the locking body 432 moves away from the inside of the controller housing 1. At this time, under the elastic force of the extension spring 433, the arc-shaped locking piece 434 moves away from the inner wall of the controller housing 1, thereby removing the cover 101 from the surface of the controller housing 1 for inspection and maintenance of the components inside the controller housing 1, so as to realize the function of convenient maintenance of the power controller.

[0032] Working principle: In use, first place the controller housing 1 in the designated position. The user inserts the cable 103 into the wiring port 104. Under the combined action of the sealing spring 232 and the sealing airbag 21 inside the high stability assembly 23, the sealing gasket 22 moves, causing the sealing gasket 22 to slide inside the guide groove 234. The guide groove 234 guides the sealing gasket 22, causing the sealing spring 232 and the sealing airbag 21 to move the sealing gasket 22 until it contacts the surface of the cable 103. Under the combined action of the sealing frame 233 and the sealing gasket 22, the cable 103 is clamped and fixed to the surface of the wiring port 104, preventing the cable 103 from coming loose from the surface of the wiring port 104 during the use of the power controller. This achieves the function of preventing the cable 103 from coming loose, thus ensuring that the cable 103 can be stably inserted into the wiring port 104 during the use of the power controller, preventing poor contact of the controller housing 1 due to the cable 103 coming loose during the use of the power controller.

[0033] Subsequently, when the controller housing 1 is in standby or other states, and the energy storage device 106 detects that there is enough energy in the external energy device, the main chip 110 can prioritize the external energy device to provide energy to the main chip 110. After the processor 111 processes the signal, the switching module 107 switches to the external energy device to provide energy to the main chip 110 according to the control signal of the main chip 110, thereby saving the energy of the energy storage device 106. When the voltage detection module 108 detects that the external energy device does not have energy or does not have enough energy, it can switch to the voltage detection module 108 to provide energy to the main chip 110.

[0034] Subsequently, after the controller housing 1 has been working for a long time, the internal temperature will continue to rise. The user controls the heat dissipation fins 36 inside the heat sink frame 31 to work. Under the combined action of the heat dissipation fins 36 and the heat conduction plate 32, the heat inside the controller housing 1 is drawn into the heat sink frame 31 through the heat dissipation holes. The dust filter 35 filters dust and impurities in the air. Then, the user pulls the dust filter 35, causing the dust filter 35 to move away from the inside of the heat sink frame 31, thereby removing the dust filter 35 from the surface of the heat sink frame 31 and cleaning the surface of the dust filter 35. This achieves the function of preventing overheating of the power controller, so that the power controller can quickly dissipate the heat inside the controller housing 1 during use, avoiding the phenomenon that the controller housing 1 will be damaged due to overheating of the internal parts of the controller housing 1 during use.

[0035] Subsequently, when any component inside the controller housing 1 is damaged, the internal parts of the controller housing 1 need to be repaired. The user loosens the mounting studs 42 on the surface of the mounting block 41, and then pulls the cover 101 upwards. When the cover 101 moves away from the inside of the controller housing 1, the cover 101 moves the rubber pad 431 away from the inside of the controller housing 1, and the locking body 432 moves away from the inside of the controller housing 1. At this time, under the elastic force of the extension spring 433, the arc-shaped locking piece 434 moves away from the inner wall of the controller housing 1, thereby removing the cover 101 from the surface of the controller housing 1. The internal components of the controller housing 1 can then be inspected and maintained, thus realizing the function of convenient maintenance of the power controller. This makes it convenient for the user to remove the cover 101 from the surface of the controller housing 1 during use, and to inspect and maintain the internal components of the controller housing 1, thereby extending the service life of the power controller and finally completing the use of the power controller.
