Description

Technical Field

[0001] This invention relates to the field of controller accessories technology, specifically a controller housing that combines sealing and heat dissipation functions. Background Technology

[0002] During the use of a controller, its internal electronic components generate a significant amount of heat. If this heat cannot be dissipated in time, it can lead to overheating of the components, thereby affecting the controller's performance and lifespan. Furthermore, in harsh working environments, such as humid or dusty conditions, the controller housing needs to have excellent sealing performance to prevent moisture, dust, and other impurities from entering and damaging the electronic components. However, traditional controller housings often struggle to simultaneously fulfill both of these crucial functions. Some housings, in pursuit of excellent sealing, employ a tightly fitted structure, but this hinders heat dissipation; while housings prioritizing heat dissipation have poor sealing performance and cannot effectively prevent the intrusion of external impurities.

[0003] Regarding the relevant technologies mentioned above, it is believed that:

[0004] Patent CN109757084A discloses a housing for a wind-cooled controller. This housing includes a lower housing and an upper housing. Multiple ventilation and heat dissipation fins are provided on the bottom wall of the lower housing and the inner wall of the upper housing. The ventilation and heat dissipation fins in the lower housing and the upper housing abut against each other to form an air duct. Ventilation openings and exhaust openings are respectively provided on two opposite side walls of the lower housing. Inclined reinforcing ribs are provided between adjacent ventilation and heat dissipation fins. The upper end face of the reinforcing rib located inside the lower housing faces the ventilation opening in a horizontal direction, while the upper end face of the reinforcing rib located inside the upper housing faces the exhaust opening in a horizontal direction. This invention has a simple structure, good heat dissipation efficiency, effectively prevents the housing from overheating, provides good protection for connecting wires, and is highly practical.

[0005] The above-mentioned device has certain shortcomings in use: it only uses a fan for heat dissipation, which is not fast or efficient enough to dissipate the heat generated by the controller. In addition, the sealing of the housing is poor, which affects the internal protection of the housing. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a controller housing that combines sealing and heat dissipation functions. It can quickly and effectively dissipate the heat generated inside the controller, ensuring that the controller operates within a suitable temperature range, thus improving the controller's performance and stability. Furthermore, it can effectively prevent external moisture, dust, and other impurities from entering the controller, protecting electronic components from the influence of the external environment and extending the controller's service life.

[0015] Furthermore, the bottom ends of both the through rod and the connecting rod are fixedly connected to meshing gears, and one side of each of the two meshing gears is rotatably connected to a cooling fan via a shaft.

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 are within the scope of protection of the present invention.

[0037] Please see Figure 1 - Figure 9 The present invention provides a technical solution: a controller housing with both sealing and heat dissipation functions, including an outer shell 1 and a housing mechanism located on one side of the outer wall of the outer shell 1. The housing mechanism includes an inner shell 8 fixed to the inner wall of the outer shell 1. A plurality of connecting ears 2 are fixedly connected to one side of the outer wall of the outer shell 1. A fixing ear 3 is fixedly connected to one side of the outer wall of the plurality of connecting ears 2 by connecting bolts. A shell cover 4 is fixedly connected to one end of the plurality of fixing ears 3. A control button 5 is fixedly connected to one side of the outer wall of the shell cover 4, and a display panel 6 is fixedly connected to the side of the outer wall of the shell cover 4 away from the control button 5.

[0038] A heat dissipation mechanism is provided on one side of the outer wall of the outer casing 1. The heat dissipation mechanism includes a heat dissipation box 14 fixed to the rear end face of the outer casing 1. A gearbox 15 is fixedly connected to the top of the heat dissipation box 14. A servo motor 16 is fixedly connected to one side of the outer wall of the gearbox 15. A motor rod 17 is fixedly connected to the output end of the servo motor 16. A drive gear 18 passes through the end of the motor rod 17 away from the servo motor 16. The heat dissipation box 14 is used for centralized heat dissipation. Its internal space is reasonably designed to effectively accommodate heat dissipation components such as the cooling fan 25. The servo motor 16 serves as a power source and can precisely control the speed of the cooling fan 25. A motor rod 17 is fixedly connected to the output end of motor 16. A drive gear 18 passes through the end of motor rod 17 furthest from servo motor 16. The outer wall of drive gear 18 drives meshing gear 19 and through rod 20 to rotate. A fixing bracket 21 passes through the bottom end of meshing gear 19 on the outer wall of through rod 20. The fixing bracket 21 is fixedly connected to one side of the top of outer casing 1, providing stable support. Meshing gear 19 meshes with one side of the outer wall of drive gear 18, and through rod 20 passes through the top of meshing gear 19. This arrangement allows through rod 20 to rotate and pass through... A fixing frame 21 passes through the bottom end of the meshing gear 19 on the outer wall of rod 20. The fixing frame 21 is fixedly connected to one side of the top of the outer shell 1. A connecting rod 22 is fixedly connected to the bottom end of the rod 20. A driving gear 23 passes through the outer wall of the connecting rod 22 below the fixing frame 21. A transmission gear 26 meshes with one side of the outer wall of the driving gear 23. A linkage rod 27 is fixedly connected to one side of the outer wall of the transmission gear 26. Both ends of the linkage rod 27 are fixedly connected to the transmission gear 26. A connecting rod 28 is connected to the outer surface of the transmission gear 26 on the other side through the driving gear 23. The top limit is rotatably connected to a fixed base 29. Through the above-mentioned transmission structure, the power of the servo motor 16 can be effectively transmitted to the cooling fan 25, driving the cooling fan 25 to rotate and dissipate heat. The bottom ends of the through rod 20 and the connecting rod 28 are both fixedly connected to the meshing gear 24. One side of each meshing gear 24 is rotatably connected to the cooling fan 25 through a shaft. Both cooling fans 25 are located on one side of the outer wall of the heat sink 14. When the servo motor 16 starts, it drives the drive gear 18 to rotate. Through a series of gear transmissions, the cooling fan 25 rotates at high speed, quickly dissipating the heat inside the heat sink 14.

[0039] The top of the outer casing 1 is provided with a top heat dissipation vent 32. A top heat dissipation bracket 30 is fixedly connected to the inner wall of the top heat dissipation vent 32. A heat dissipation plate 31 is fixedly connected to the top of the top heat dissipation bracket 30. The heat dissipation plate 31 is made of a material with high thermal conductivity, such as copper plate, which can quickly conduct heat inside the outer casing 1 to the outside. A heat conduction block 33 is provided on the inner wall of the top heat dissipation vent 32. A fixing block 34 is fixedly connected to the bottom of multiple heat conduction blocks 33. A through joint 35 is fixedly connected to the bottom of each fixing block 34. Coolant heat dissipation pipes 36 pass through the inner walls of multiple through joints 35. Fixing rods 37 are fixedly connected to the outer walls of multiple coolant heat dissipation pipes 36. Multiple coolant heat dissipation pipes 36 are all located on the outer wall of the inner casing 8. The inner casing 8 transfers the heat generated by the controller to the coolant heat dissipation pipes 36 through the heat conduction block 33. The coolant circulates in the coolant heat dissipation pipes 36, carrying away heat and further improving heat dissipation efficiency.

[0040] A sealing mechanism is provided on one side of the outer wall of the inner shell 8. The sealing mechanism includes a sealing layer 13 fixed to one side of the outer wall of the inner shell 8. A pressure plate 40 is fixedly connected to one side of the outer wall of the sealing layer 13. A protective layer 41 is sleeved on the outer wall of the pressure plate 40. The sealing layer 13 is made of rubber elastic sealing material, which has good sealing performance and can effectively prevent external impurities from entering the interior of the inner shell 8. The pressure plate 40 is used to enhance the sealing effect of the sealing layer 13 so that it can better fit the outer wall of the inner shell 8. The protective layer 41 is made of wear-resistant and corrosion-resistant polytetrafluoroethylene, which can protect the pressure plate 40 from damage by external factors.

[0041] Multiple spring rods 9 are fixedly connected to one side of the outer wall of the pressure plate 40. A push plate 7 is fixedly connected to one end of the multiple spring rods 9 away from the pressure plate 40. A push shell 12 is provided on one side of the outer wall of the push plate 7. The side of the push shell 12 away from the push plate 7 is fixedly connected to one side of the outer wall of the cover 4. The spring rods 9 are made of high-strength spring steel and have good elasticity. When the cover 4 is installed on the outer shell 1, the push shell 12 pushes the push plate 7, and the spring rods 9 apply pressure to the pressure plate 40, so that the sealing layer 13 fits tightly against the inner shell 8, thereby achieving a good sealing effect.

[0042] The inner shell 8 is fixedly connected to the rear end face of the inner shell heat conduction plate 38. The inner shell heat conduction plate 38 can enhance the heat conduction performance of the inner shell 8, so that the heat generated by the internal electronic components can be conducted to the heat dissipation components such as the coolant heat pipe 36 more quickly. The outer wall of the inner shell 8 is fixedly connected to a buffer frame 39 on one side of the sealing layer 13. The buffer frame 39 is made of elastic material, such as rubber, which can play a buffering role when subjected to external impact, protecting the inner shell 8 and the internal electronic components. Both sides of the outer wall of the outer shell 1 are fixedly connected to control connectors 10. The inner walls of multiple control connectors 10 are fixedly connected to internal connecting cores 11. The control connectors 10 are used to connect external devices to realize signal transmission and control command transmission between the controller and external devices.

[0043] During operation, the inner housing 8 is fixed to the inner wall of the outer housing 1, ensuring a secure installation and correct positioning of the sealing layer 13. The various components of the sealing mechanism are then installed, sequentially connecting the pressure plate 40, protective layer 41, spring rod 9, and push plate 7. The push shell 12 is then fixedly connected to the cover 4 to ensure a tight seal. The electronic components inside the controller generate heat, which is transferred through the inner housing 8 to the inner housing heat-conducting plate 38, and then through the heat conduction block 33 to the coolant cooling pipe 36. The coolant circulates within the coolant cooling pipe 36, carrying away some of the heat. Simultaneously, the servo motor 16 starts, driving the cooling fan 25 to dissipate heat from the heat sink 14, further reducing the controller's temperature. The sealing mechanism functions effectively when the controller is in harsh environments such as humid or dusty conditions. The push shell 12 applies pressure to the pressure plate 40 via the push plate 7 and spring rod 9, ensuring the sealing layer 13 fits tightly against the inner housing 8, effectively preventing external impurities from entering the controller. The user operates the controller via the control button 5, and the controller's operating status and related parameters are displayed on the display panel 6. Meanwhile, through the control connector 10 and the internal connection core 11, the controller can be connected to external devices to realize signal transmission and control command transmission.
