Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicles, and more specifically, to an automotive fan controller with a sound insulation component. Background Art

[0002] With the rapid development of the automotive industry, the role of the automotive fan controller is very important. It mainly controls the operation of the cooling fan, and the function of the cooling fan is to dissipate heat from the engine and the coolant, ensuring that the engine does not malfunction due to high temperature;

[0003] In the prior art, the motor controller for an automotive fan includes a base and a housing. A cavity for installing a PCB board and electronic components is formed between the housing and the base. Among them, the housing is made of plastic and the base is made of aluminum, resulting in relatively weak strength of the housing and affecting the voltage resistance performance of the fan controller.

[0004] After retrieval, the Chinese patent with the authorization announcement number CN218679614U discloses a brushless motor controller for a voltage-resistant automotive fan. The structure improves the structure of the housing. Grid-shaped reinforcing ribs and longitudinal reinforcing ribs are respectively arranged on the front panel and the side panel of the housing to enhance the structural strength. An installation plate is also arranged on the side panel, and the lowermost end of the longitudinal reinforcing rib and the installation plate both support on the base, thereby improving the overall strength and further enhancing the voltage resistance performance.

[0005] However, in actual use, this structure directly fixes the housing and the internal electronic components to the installation component part of the vehicle through the base. Then, when the fan controller works, the mechanical vibration generated will be transmitted to the surrounding components, thereby increasing the interference of noise. Summary of the Utility Model

[0006] In order to overcome the above-mentioned defects of the prior art, the utility model provides an automotive fan controller with a sound insulation component to solve the problems raised in the above background art.

[0007] To achieve the above object, the utility model provides the following technical solutions:

[0008] An automotive fan controller with a sound insulation component includes a top plate. A sealing ring is fixedly arranged at the bottom of the top plate. A housing is arranged at the bottom of the sealing ring. A sealing groove is formed on the surface of the housing. The sealing ring is inserted into the sealing groove. A shock absorption mechanism is arranged at the bottom of the housing;

[0009] The shock absorption mechanism includes a shock pad fixedly arranged at the bottom of the housing. Two fixing blocks are fixedly arranged at the bottom of the shock pad. First connecting bars are hinged on both sides of the two fixing blocks. One end of each first connecting bar is hinged with a movable cylinder. A connecting column is slidably connected inside the movable cylinder, and the cross-section of the connecting column is U-shaped. A spring is movably sleeved on the connecting column, and both ends of the spring are connected to the movable cylinder. Second connecting bars are hinged on both sides of the movable cylinder. One side of each second connecting bar is hinged with a movable block, and the cross-section of the movable block is T-shaped. A fixed seat is fixedly arranged at the bottom of the connecting column. An activity groove is formed on the surface of the fixed seat. The movable block is slidably connected with the activity groove. Side ears are fixedly arranged on both sides of the fixed seat, and threaded holes are formed on the surfaces of the side ears.

[0010] By adopting the above technical solutions: In order to achieve an effective shock absorption effect and combine with the dynamic balance technology to ensure the stable operation of the fan controller during the working process, effectively reduce noise, and improve the overall durability and quietness.

[0011] As a further description of the above technical solutions: A sound insulation mechanism is arranged inside the housing. The sound insulation mechanism includes a sound insulation cavity formed inside the housing. Sound insulation cotton is fixedly arranged on the inner wall of the housing, and the sound insulation cotton is made of high-density foam.

[0012] By adopting the above technical solutions: In order to reduce the direct propagation path of noise, enhance the sound insulation effect, and effectively absorb and isolate the noise generated during the operation of the fan controller.

[0013] As a further description of the above technical solutions: A fixed frame is fixedly arranged on one side of the housing. A threaded groove is formed on the surface of the fixed frame. A threaded column is threadedly connected inside the threaded groove. One side of the threaded column is rotatably connected with a fixing plate. A rubber layer is fixedly arranged on one side of the fixing plate. Fixing pieces are fixedly arranged on both sides of the top plate, and the fixing pieces are inserted into the fixed frame. A fan controller is fixedly arranged inside the housing.

[0014] By adopting the above technical solutions: In order to strengthen the sealing effect, reduce external noise interference and internal noise leakage, and at the same time consider the convenience of disassembly and assembly for easy maintenance.

[0015] The technical effects and advantages of the present utility model:

[0016] 1. By setting up a shock-absorbing mechanism, compared with the prior art, initial buffering is carried out through a shock-absorbing pad, and then it is conveyed to the fixed block. The fixed block transmits the vibration to the first connecting bar, and through the first connecting bar, it is transmitted to the movable cylinder, enabling the movable cylinder to slide on the connecting column. The movement of the movable cylinder drives the spring to move, and at the same time drives the second connecting bar and the movable block to move. The movable block moves in the movable groove opened on the surface of the fixed seat, thus achieving the shock-absorbing effect, effectively reducing the diffusion of mechanical vibration generated during the operation of the fan controller, reducing the resulting noise, and also effectively preventing external forces from affecting the fan controller, effectively improving the use safety of the device.

[0017] 2. By setting up a sound-insulating mechanism, compared with the prior art, when moving the top plate downward, the sealing ring is inserted into the sealing groove opened on the surface of the housing. At the same time, the fixing pieces on both sides of the top plate are also inserted into the interior of the fixed frame. Then, rotating the threaded column drives the fixing plate to approach one side of the fixing piece until it contacts the fixing piece for fixation, effectively strengthening the sealing effect, ensuring that the working environment of the fan controller is isolated from the outside, reducing external noise interference and internal noise leakage. Moreover, the sound-insulating cavity reduces the direct propagation path of noise, enhancing the sound-insulating effect. At the same time, the sound-insulating cotton can also effectively absorb and isolate the noise generated during the operation of the fan controller, further improving the sound-insulating effect.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] The embodiments of the present application disclose a vehicle blower controller with a sound insulation component as shown in Figures 1-6 Figure [not provided], which includes a top plate 1. A sealing ring 2 is fixedly arranged at the bottom of the top plate 1. A housing 3 is arranged at the bottom of the sealing ring 2. A sealing groove is formed on the surface of the housing 3. The sealing ring 2 is inserted into the sealing groove. A shock absorption mechanism is arranged at the bottom of the housing 3;

[0027] The shock absorption mechanism includes a shock pad 4 fixedly arranged at the bottom of the housing 3. Two fixing blocks 5 are fixedly arranged at the bottom of the shock pad 4. First connecting bars 6 are hinged on both sides of the two fixing blocks 5. One end of the first connecting bar 6 is hinged with a movable cylinder 7. A connecting column 8 is slidably connected inside the movable cylinder 7, and the cross section of the connecting column 8 is U-shaped. A spring 9 is movably sleeved on the connecting column 8, and both ends of the spring 9 are connected to the movable cylinder 7. Second connecting bars 10 are hinged on both sides of the movable cylinder 7. One side of the second connecting bar 10 is hinged with a movable block 11, and the cross section of the movable block 11 is T-shaped. A fixed seat 12 is fixedly arranged at the bottom of the connecting column 8. An activity groove is formed on the surface of the fixed seat 12. The movable block 11 is slidably connected with the activity groove. Side ears 13 are fixedly arranged on both sides of the fixed seat 12. Threaded holes are formed on the surface of the side ears 13. When mechanical vibration is generated during the operation of the blower controller 20 inside the housing 3, it is first preliminarily buffered by the shock pad 4, and then transmitted to the fixing block 5. The fixing block 5 transmits the vibration to the first connecting bar 6, and through the first connecting bar 6, it is transmitted to the movable cylinder 7, causing the movable cylinder 7 to slide on the connecting column 8. The movement of the movable cylinder 7 drives the spring 9 to compress, and also drives the second connecting bar 10 and the movable block 11 to move. The movable block 11 moves in the activity groove formed on the surface of the fixed seat 12, thereby achieving the shock absorption effect, effectively reducing the diffusion of mechanical vibration generated during the operation of the blower controller 20, and reducing the resulting noise.

[0028] Refer to Figures 2-4As shown, a sound insulation mechanism is arranged inside the housing 3. The sound insulation mechanism includes a sound insulation cavity 14 opened inside the housing 3. The inner wall of the housing 3 is fixedly provided with sound insulation cotton 15. The sound insulation cotton 15 is made of high-density foam. By providing the sound insulation cavity 14, the direct propagation path of noise is reduced, and the sound insulation effect is enhanced. At the same time, the sound insulation cotton 15 is made of high-density foam and has excellent sound absorption and sound insulation performance, which can effectively absorb and isolate the noise generated during the operation of the fan controller 20, further improving the sound insulation effect.

[0029] Referring to Figures 4-6 As shown, a fixing frame 16 is fixedly arranged on one side of the housing 3. Thread grooves are opened on the surface of the fixing frame 16. A threaded column 17 is threadedly connected inside the thread grooves. One side of the threaded column 17 is rotatably connected to a fixing plate 18. A rubber layer is fixedly arranged on one side of the fixing plate 18. Fixing pieces 19 are fixedly arranged on both sides of the top plate 1. The fixing pieces 19 are inserted into the fixing frame 16. A fan controller 20 is fixedly arranged inside the housing 3. Move the top plate 1 downward to insert the sealing ring 2 into the sealing groove opened on the surface of the housing 3. At the same time, the fixing pieces 19 on both sides of the top plate 1 are also inserted into the inside of the fixing frame 16. Then rotate the threaded column 17 to drive the threaded column 17 to rotate in the thread grooves opened on the surface of the fixing frame 16. Then the threaded column 17 drives the fixing plate 18 to approach one side of the fixing piece 19 inside the fixing frame 16 until it contacts the fixing piece 19 for fixation. At the same time, the rubber layer arranged on one side of the fixing plate 18 not only enhances the anti-slip effect but also effectively prevents the surface of the fixing piece 19 from being damaged by friction. Then, through the cooperation of external bolts and the side ears 13, the fixing seat 12 is fixed to the installation component part of the vehicle, and the installation is completed, effectively enhancing the sealing effect and ensuring that the working environment of the fan controller 20 is isolated from the outside, reducing external noise interference and internal noise leakage.

[0030] The working principle of the present utility model:

[0031] The present utility model is an automotive fan controller with a sound insulation component. When the device is in use, first install the top plate 1 on the top of the housing 3. Move the top plate 1 downward to insert the sealing ring 2 into the sealing groove opened on the surface of the housing 3. At the same time, the fixing pieces 19 on both sides of the top plate 1 are also inserted into the inside of the fixing frame 16. Then rotate the threaded column 17 to drive the threaded column 17 to rotate in the thread grooves opened on the surface of the fixing frame 16. Then the threaded column 17 drives the fixing plate 18 to approach one side of the fixing piece 19 inside the fixing frame 16 until it contacts the fixing piece 19 for fixation. At the same time, the rubber layer arranged on one side of the fixing plate 18 not only enhances the anti-slip effect but also effectively prevents the surface of the fixing piece 19 from being damaged by friction. Then, through the cooperation of external bolts and the side ears 13, the fixing seat 12 is fixed to the installation component part of the vehicle, and the installation is completed, effectively enhancing the sealing effect and ensuring that the working environment of the fan controller 20 is isolated from the outside, reducing external noise interference and internal noise leakage;

[0032] When the mechanical vibration generated during the operation of the fan controller 20 inside the housing 3 occurs, it is first preliminarily buffered by the shock pad 4 and then transmitted to the fixing block 5. The fixing block 5 transmits the vibration to the first connecting bar 6, and through the first connecting bar 6, it is transmitted to the movable cylinder 7, causing the movable cylinder 7 to slide on the connecting column 8. The movement of the movable cylinder 7 drives the spring 9 to compress and also drives the second connecting bar 10 and the movable block 11 to move. The movable block 11 moves within the movable groove formed on the surface of the fixed seat 12, thereby achieving the shock absorption effect, effectively reducing the spread of the mechanical vibration generated during the operation of the fan controller 20, and reducing the noise generated thereby;

[0033] By providing the sound insulation cavity 14, the direct propagation path of noise is reduced, enhancing the sound insulation effect. At the same time, the sound insulation cotton 15 is made of high-density foam and has excellent sound absorption and sound insulation properties, capable of effectively absorbing and isolating the noise generated during the operation of the fan controller 20, further improving the sound insulation effect.

[0034] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
