Description

Technical Field

[0001] This utility model belongs to the field of cooling fan technology, and relates to a cooling fan with automatic position adjustment. Background Technology

[0002] In the automotive industry, the main function of cooling fans is to help cool the engine and reduce engine overheating. They blow air towards the radiator, which then dissipates the heat generated by the engine into the air.

[0003] Cooling fans are typically installed to the front engine of a vehicle using bolts or other fasteners. When the cooling fan is fixed in a standard position, the center position of the air intake grille varies depending on the vehicle's height, length, and width. In this case, it is not easy for the cooling fan to be aligned with the center of the vehicle's air intake grille, which can restrict its airflow and reduce airflow utilization. Insufficient airflow makes it difficult for the radiator to effectively dissipate heat into the air, thus reducing its cooling effect on the radiator. Utility Model Content

[0004] The technical problem this utility model aims to solve is that: cooling fans are generally installed to the front engine of a vehicle using bolts or other fasteners. When the cooling fan is fixed in a standard position, the center position of the air intake grille varies depending on the vehicle's height and width when it is installed on different vehicles. In this case, it is not easy for the cooling fan to be aligned with the center of the vehicle's air intake grille, which can restrict its airflow and reduce the airflow utilization rate. This results in insufficient airflow, making it difficult for the radiator to effectively dissipate heat into the air, thus reducing its cooling effect on the radiator.

[0005] The present invention describes an automatically adjustable cooling fan, comprising a fan body, with connecting blocks symmetrically fixed to both sides of the outer wall of the fan body, and a connecting block also fixed to the middle of one end of the fan body. Support frames are fixed to both sides of the outer wall of the fan body away from the connecting blocks, and a camera is installed inside the support frame.

[0006] The lifting assembly, which is connected to multiple sets of connecting blocks, is used to drive the fan body to perform lifting and lowering movements as well as movement in the vertical and horizontal coordinate directions;

[0007] The cleaning component, which is connected to the support frame, can automatically wipe the dust adhering to the camera surface when the fan body moves up and down in conjunction with the lifting component.

[0008] The lifting assembly includes a slide rod and a first lead screw. The slide rod passes through the connecting blocks located on both sides of the outer wall of the fan body. The first lead screw is connected to the connecting block at the middle of one end of the fan body by a lead screw and nut pair. The ends of the slide rod and the first lead screw are fixed to the base. A second servo motor is installed on the base, and the output end of the second servo motor is connected to the first lead screw.

[0009] The lifting assembly further includes a first guide rod and a third lead screw. The first guide rod slides through both ends of the base. The third lead screw is connected to a lead screw and nut pair in the middle of the base. A first support frame is fixed to both ends of the first guide rod. A third servo motor is installed at one end of the first support frame. The output end of the third servo motor is connected to the third lead screw. A second lead screw is connected to the lead screw and nut pair in the middle of the first support frame. A second guide rod slides through both ends of the first support frame. A second support frame is fixed to both ends of the second guide rod. A first servo motor is installed at one end of the second support frame. The output end of the first servo motor is connected to the second lead screw.

[0010] The cleaning assembly includes a rack, a rotating rod, a first bracket, and a second bracket. The rack is fixed to the base. The rotating rod is rotatably mounted on the side of the support frame away from the camera. Both the first and second brackets are fixed to the outer wall of the fan body. The end of the rotating rod inside the support frame is equipped with a cleaning bracket. The end of the rotating rod on the outer wall of the support frame is drivenly connected to a second pulley set. One end of the first bracket is rotatably connected to a first bevel gear. The second bracket is rotatably connected to a second bevel gear that meshes with the first bevel gear. One end of the first bevel gear is drivenly connected to the second pulley set. One end of the second bevel gear is equipped with a second transmission gear that meshes with the rack.

[0011] The cleaning assembly also includes a locking block and a locking slot. The locking block is mounted around one end of the rotating rod located inside the support frame. The locking slot is opened around the inner wall of the end of the cleaning bracket connected to the rotating rod. The cleaning bracket and the rotating rod are slidably connected. A limit block is fixed to the end of the rotating rod near the camera.

[0012] Both the card slot and the card block surface are provided with rubber pads.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the lifting component can drive the fan body to move up and down and move in the longitudinal and transverse directions to adapt to vehicles of different heights, lengths and widths, improve the applicability of the fan body to different vehicle bodies, and, in conjunction with the image transmitted by the camera, view the position of the fan body outside the vehicle body in real time, so that subsequent personnel can make precise adjustments to the position of the fan body according to the specific conditions of the vehicle to ensure that the fan body is aligned with the center of the vehicle's air intake grille.

[0014] The cleaning component, in conjunction with the lifting component, automatically wipes away dust adhering to the camera surface as the fan body moves up and down. This reduces the impact of dust on the camera's image quality, preventing operators from accurately obtaining the fan body's position and status information. Attached Figure Description

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] Example 1

[0027] like Figures 1-5 As shown, the device includes a fan body 1, which is the main part of the cooling fan and is responsible for generating cooling air. Connecting blocks 3 are symmetrically fixed to both sides of the outer wall of the fan body 1, and a connecting block 3 is also fixed to the middle of the end of the fan body 1. The connecting blocks 3 are used to connect to the lifting assembly. Support frames 4 are fixed to both sides of the outer wall of the fan body 1 away from the connecting blocks 3. Cameras 5 are installed inside the support frames 4. The cameras 5 are used to transmit images so that personnel can view the relative position of the fan body 1 outside the vehicle body in real time.

[0028] The lifting assembly is connected to multiple sets of connecting blocks 3. The lifting assembly can drive the fan body 1 to move up and down and move in the longitudinal and transverse directions to adapt to the height of different vehicles, improve the applicability of the fan body 1 to different vehicle bodies, and, together with the image transmitted by the camera 5, monitor the position of the fan body 1 outside the vehicle body in real time, so that the personnel can make precise adjustments to the position of the fan body 1 according to the specific conditions of the vehicle to ensure that the fan body 1 is aligned with the center of the vehicle's air intake grille.

[0029] The cleaning component, which is connected to the support frame 4, can automatically wipe the dust on the surface of the camera 5 when the fan body 1 is raised and lowered in conjunction with the lifting component. This reduces the impact of dust on the imaging quality of the camera 5, thus preventing the operator from accurately obtaining the position and status information of the fan body 1.

[0030] Example 2

[0031] like Figures 1-3 As shown, the lifting assembly includes a slide rod 6 and a first lead screw 7. The slide rod 6 passes through the connecting blocks 3 located on both sides of the outer wall of the fan body 1. The first lead screw 7 is connected to the connecting block 3 at the middle of one end of the fan body 1 by a lead screw and nut pair. The ends of both the slide rod 6 and the first lead screw 7 are fixedly connected to the base 8. A second servo motor 9 is installed on the base 8. The output end of the second servo motor 9 is connected to the first lead screw 7.

[0032] like Figures 1-3 As shown, the lifting assembly also includes a first guide rod 12 and a third lead screw 17. The first guide rod 12 slides through both ends of the base 8. The third lead screw 17 is connected to the lead screw nut pair in the middle of the base 8. A first support frame 11 is fixedly connected to both ends of the first guide rod 12. A third servo motor 13 is installed at one end of the first support frame 11. The output end of the third servo motor 13 is connected to the third lead screw 17. A second lead screw 14 is connected to the lead screw nut pair in the middle of the first support frame 11. A second guide rod 16 slides through both ends of the first support frame 11. A second support frame 15 is fixedly connected to both ends of the second guide rod 16. A first servo motor 2 is installed at one end of the second support frame 15. The output end of the first servo motor 2 is connected to the second lead screw 14.

[0033] During operation, the second receiving frame 15 is installed on the vehicle body. After installation, the image transmitted by the camera 5 drives the output of the second servo motor 9 to rotate in both directions, thereby rotating the first lead screw 7. The slide rod 6 guides the fan body 1, allowing it to move vertically up and down. Simultaneously, the output of the first servo motor 2 is driven to rotate in both directions, rotating the second lead screw 14. At this time, guided by the second guide rod 16, the first receiving frame 11 can move linearly in the lateral coordinate direction, thereby adjusting the lateral position between the fan body 1 and the vehicle body. Furthermore, by driving the output of the third servo motor 13 to rotate in both directions, the third lead screw 17 is rotated. At this time, under the guidance of the first guide rod 12, the base 8 can move linearly in the longitudinal coordinate direction, thereby adjusting the longitudinal position between the fan body 1 and the vehicle body, so as to achieve multi-directional adjustment of the fan body 1. With the cooperation of the image transmitted by the camera 5, it is convenient for personnel to operate the fan body 1 to be aligned with the center of the vehicle's air intake grille. At the same time, the second servo motor 9 is connected to the vehicle's signal, and the parameters for this adjustment can be input into the vehicle's internal system for subsequent monitoring and adjustment.

[0034] Example 3

[0035] like Figures 1-5 As shown, the cleaning assembly includes a rack 10, a rotating rod 18, a first bracket 21, and a second bracket 27. The rack 10 is fixed to the base 8. The rotating rod 18 is rotatably mounted on the side of the support frame 4 away from the camera 5. The first bracket 21 and the second bracket 27 are both fixed to the outer wall of the fan body 1. One end of the rotating rod 18 located inside the support frame 4 is provided with a cleaning bracket 19. The other end of the rotating rod 18 located on the outer wall of the support frame 4 is connected to a second pulley group 20. One end of the first bracket 21 is rotatably connected to a first bevel gear 22. The second bracket 27 is rotatably connected to a second bevel gear 23 that meshes with the first bevel gear 22. One end of the first bevel gear 22 is connected to the second pulley group 20. One end of the second bevel gear 23 is provided with a second transmission gear 24 that meshes with the rack 10.

[0036] like Figure 4 As shown, the cleaning assembly also includes a locking block 25 and a slot 26. The locking block 25 is mounted around one end of the rotating rod 18 located inside the support frame 4. The slot 26 is opened around the inner wall of the end of the cleaning bracket 19 connected to the rotating rod 18. The cleaning bracket 19 and the rotating rod 18 are slidably connected. A limit block 28 is fixed to the end of the rotating rod 18 near the camera 5. When adjusting the fan body 1 to align with the center of the vehicle's air intake grille, the cleaning bracket 19 is pulled to disengage the locking block 25 from the slot 26, causing the cleaning bracket 19 to rotate with the rotating rod 18, thus cleaning the camera 5. After the adjustment is completed, the cleaning bracket 19 is pushed to reconnect the slot 26 and the locking block 25.

[0037] like Figure 4 As shown, both the card slot 26 and the card block 25 are provided with rubber pads. The friction generated between the rubber pads is used to improve the stability of the connection between the card slot 26 and the card block 25.

[0038] During operation, when the fan body 1 reciprocates on the slide rod 6 and the first lead screw 7, the second transmission gear 24 meshes with the rack 10 and rotates. The second bevel gear 23 meshes with the first bevel gear 22 and drives it to rotate. The second pulley group 20 drives the rotating rod 18 to rotate, thereby driving the cleaning bracket 19 to move in a circular motion around the surface of the camera 5 to wipe the surface of the camera 5 and reduce the impact of dust on the imaging quality of the camera 5.

[0039] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, and obviously, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
