Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning fans, and specifically to a fan device in an air-conditioning system. Background Art

[0002] The functions of the blower in an automotive air-conditioning system mainly include delivering the cold air above the evaporator of the air conditioner or the warm air from the heater core to the passenger compartment. When the passengers select the cooling mode in the vehicle, the blower sends in the cool air, effectively reducing the temperature inside the vehicle and providing a pleasant riding environment; while in the heating mode, it is responsible for delivering the warm air. In addition, the blower is also responsible for regulating the temperature inside the vehicle and improving the air quality. By controlling the voltage or adjusting the resistance, multi-speed adjustment of the blower speed is achieved to meet different air speed requirements.

[0003] The operation of the blower is driven by a seat with a motor to drive the impeller to rotate. A variety of control and sensing components are also installed on the seat. When the impeller rotates, the outside air is sucked into the inside of the impeller and then diffuses towards the edge. The incoming airflow will also blow and cool the basic devices or components on the seat. Under long-term blowing, the dust in the air will gradually erode the basic devices and components. Therefore, it is necessary to limit this part of the impact airflow. When the seat needs to dissipate heat, the air flow will be introduced. If there is no need for heat dissipation, for example, in the cold winter, the mechanism on the seat does not need ventilation and heat dissipation, then it is necessary to control the airflow entering the impeller to only diffuse around and not impact the base; in addition, when the vehicle is parked under a tree, leaves often fall on the vehicle. When the blower works, the leaves enter the impeller through the air inlet, which may cause potential safety hazards. Based on the above problems, the present invention provides a fan device in an air-conditioning system. Summary of the Invention

[0038] The spring assembly 18 further includes a C-shaped elastic piece 29 fixed to the bracket 28, and a stop block 31 fixed to the bottom surface of one end of the circulation cylinder 32. One end of the vertical shaft 39 intercepts the stop block 31. A disc holder is provided on the bottom surface of the circulation cylinder 32, and the middle of the disc holder is clamped with the annular groove opened on the storage pressure shaft 33 through a through hole provided.

One end of the lead-out shaft 36 is provided with a bevel gear to reversely transmit power with the bevel gear arranged at the end of the inclined worm 19. The inclined worm 19 is movably sleeved in the through hole opened on the tail frame 40.

[0040] The limiting body 35 includes a small control frame 43 fixed to the tail frame 40, a neck shaft 41, a short shaft 42 and a screw post 45 supported on the small control frame 43, and a short prism 44 fixed to one end of the short shaft 42. The lead-out shaft 36, the neck shaft 41 and the short shaft 42 are respectively movably sleeved in different through holes opened on the small control frame 43.

[0041] One end of the neck shaft 41 is provided with a column gear to mesh and transmit power with a row of teeth arranged on the Z-shaped column 13. The other end of the neck shaft 41 is provided with a bevel gear to reversely transmit power with the bevel gear arranged at the end of the short shaft 42. The short prism 44 slides and inserts into the prism hole opened at one end of the screw post 45, and the screw post 45 passes through the threaded hole opened on the small control frame 43.

[0042] The overlapping body 38 includes an L-shaped control plate 49 sliding through the plate hole opened on the tail frame 40, a continuation shaft 48 sliding through the through hole opened at one end of the L-shaped control plate 49, a continuation gear 46 fixed to one end of the continuation shaft 48, and a spring 47 supported between the continuation gear 46 and the L-shaped control plate 49. The spring 47 is sleeved on the continuation shaft 48. The other end of the continuation shaft 48 is fixedly sleeved with an intercepting ring body. One end of the vertical shaft 39 is always meshed with the continuation gear 46 through a gear. The continuation gear 46 is axially moved to establish meshing with the lead-out gear 37, or the end of the rotated screw post 45 intercepts the continuation gear 46 to prevent the continuation gear 46 from meshing with the lead-out gear 37. The other end of the vertical shaft 39 is fixedly provided with a gear to mesh and transmit power with the stationary external gear ring 9.

[0043] During the operation of the fan, the motor drives the motor shaft 2, which in turn drives the protective cover 6 and the impeller 5 to rotate synchronously. The hemispherical frame 8 rotates synchronously. The stationary external gear ring 9 in the switching integrator 4 is fixed on the machine base 1, and the remaining devices rotate with the motor shaft 2. In this way, the vertical shaft 39 moves around the stationary external gear ring 9. The vertical shaft 39 rotates continuously to drive the follow-up gear 46. At this time, the follow-up gear 46 rotates in place. The L-shaped control plate 49 is externally connected to a magnetic attraction mechanism in the prior art. Specifically, a temperature detection element is installed in the protective cover 6 to detect the temperature inside the protective cover 6. If the temperature is too high, a signal will be sent to the fan control system, and the fan control system will supply power to the magnetic attraction mechanism, thereby magnetically attracting and controlling the movement of the L-shaped control plate 49. Figure 10 The L-shaped control plate 49 in it rises, and then drives the follow-up gear 46 to rise through the spring 47. The follow-up gear 46 and the leading-out gear 37 establish meshing. The continuously rotating follow-up gear 46 drives the leading-out gear 37, and then drives the inclined worm 19 through the leading-out shaft 36. Next, it drives the pressure accumulator shaft 33 through the pressure accumulator gear 34. The rotation of the pressure accumulator shaft 33 causes the blocking block 31 to contract and store energy. Once the stored energy is greater than the clamping position of the C-shaped elastic piece 29, the spring 30 will release the pressure, and then the circulating cylinder 32 rotates quickly for one circle. The circulating cylinder 32 drives the side control shaft 27, and then drives the wheel disc shaft 22 to rotate for one circle through the multi-turn flat worm 23. Figure 8 The wheel disc 21 in it rotates for one circle, and pushes and pulls the column rack 26 through the wheel swing column 24. The column rack 26 reciprocates once and translates back and forth, thereby driving the swing drum 16. The swing drum 16 rotates back and forth at a fixed angle once, causing all the support columns 14 to swing back and forth, thereby controlling the arc plate door 7 to swing back and forth once. The arc plate hole on the protective cover 6 will open and then be blocked again. During this process, the air flow hitting the impeller 5 will further hit into the protective cover 6, and blow and cool the component devices in the protective cover 6.

[0044] After the temperature inside the protective cover 6 returns to normal, the follow-up gear 46 at the transmission source separates from the leading-out gear 37 again, and the subsequent transmission is interrupted. The arc plate door 7 will not swing, and the arc plate door 7 blocks the arc plate hole on the protective cover 6. In this way, the air flow injected into the impeller 5 can only diffuse in all directions.

[0045] If a leaf flies into the impeller 5, under the blowing of the air flow, the leaf presses the hemispherical frame 8, the hemispherical frame 8 moves closer to the protective cover 6, the hemispherical frame 8 drives the Z-shaped column 13 to move, the Z-shaped column 13 drives the neck shaft 41 to rotate, and then drives the short prism 44 to rotate through the short shaft 42. The screw column 45 rotates on the stationary small control frame 43. Figure 10After the bottom end of the screw post 45 descends, it exceeds the plane where the bottom end of the lead-out gear 37 is located. In this way, after the continuation gear 46 rises, it contacts prior to the bottom end of the screw post 45. The continuation gear 46 and the lead-out gear 37 cannot establish meshing, which ultimately affects the swing of the arc plate door 7. The arc plate door 7 always blocks the arc plate hole on the protective cover 6, that is, the leaves fall into the impeller 5. Once the leaves dry, they may break into small pieces. After the arc plate hole on the protective cover 6 is blocked, the small pieces of leaves cannot invade the inside of the protective cover 6. Once the dry leaves enter the inside of the protective cover 6 and encounter the heating component device inside the protective cover 6, the leaves may be ignited. Therefore, the present invention intercepts in advance through the hemispherical frame 8. After detecting the leaves, the arc plate hole on the protective cover 6 is completely blocked. If the temperature inside the protective cover 6 rises again, the fan control system will send the continuous overheat information to the vehicle central control system, so that the driver can understand the problem.
