Description

Technical Field

[0001] This utility model relates to the field of aircraft auxiliary equipment technology, specifically an auxiliary safety driving device for an aircraft tractor. Background Technology

[0002] Aircraft towing vehicles are specialized ground support vehicles used in the aviation industry for maneuvering and towing aircraft. They are mainly used for towing aircraft on the ground at airports, and can also be used to move large parts or the entire aircraft during the aircraft manufacturing process. They are characterized by their low body, heavy weight, and strong traction force. According to the different towing methods, they can be divided into towing vehicles with poles and towing vehicles without poles.

[0003] In the prior art, there is an aircraft towing vehicle with patent publication number CN215436983U. The driver and aircraft guide of the above patent can see the direction of the aircraft being pushed out by the towing vehicle through indicator lights and left and right guide lights, making the entire aircraft push-out guidance process more intuitive. However, in actual use, there are still the following shortcomings: the towing vehicle usually observes the road conditions through the rearview mirror while driving. The rearview mirrors of the existing towing vehicles are not easy to adjust according to different types of aircraft. Larger aircraft can easily obstruct the view in the rearview mirror, thereby affecting the safety of the towing vehicle during driving. Moreover, the rearview mirror is very easy to get dusty, and a blurry rearview mirror can easily cause safety problems when the towing vehicle is driving.

[0004] Therefore, there is a need for an auxiliary safety driving device for aircraft towing vehicles to solve the problems in the existing technology where the rearview mirrors of towing vehicles are not easily adjustable to adapt to different types of aircraft, and blurry rearview mirrors can easily affect the safe driving of towing vehicles. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary safety driving device for aircraft towing vehicles, in order to solve the problems in the prior art where the rearview mirrors of towing vehicles are not easily adjustable to adapt to different types of aircraft, and where blurry rearview mirrors can easily affect the safe driving of towing vehicles.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary safety driving device for an aircraft towing vehicle, comprising a vehicle body, a cockpit being provided on one side of the top surface of the vehicle body, two symmetrically distributed fixing blocks being fixedly connected to the top of the outer wall of one side of the cockpit, an adjustment mechanism being provided on the outer wall of one end of the fixing blocks, two outer shells being installed on the cockpit through two sets of adjustment mechanisms, a lens being embedded in the outer wall of one side of the outer shell, and a cleaning component being provided on the top surface of the outer shell;

[0007] The adjustment mechanism includes a mounting shell, one end of which is fixedly connected to the outer wall of a fixed block. A drive screw is rotatably connected between the inner walls of both ends of the mounting shell. A driven bevel gear is fastened to one end of the outer surface of the drive screw. A guide rod is fixedly connected between the inner walls of both ends of the mounting shell. A movable plate is slidably sleeved on the outer surface of the guide rod. A sliding rod is fixedly connected to the outer wall of one end of the movable plate.

[0008] It should be noted in the solution that the cleaning component includes two parallel bearing seats and a slide groove. Both bearing seats are fixedly connected to the top surface of the housing. A reciprocating screw is rotatably connected between the two bearing seats. A drive motor is fixedly connected to one end of the outer wall of one of the bearing seats. A moving part is threadedly connected to the outer surface of the reciprocating screw. A scraper is fixedly connected to one side of the bottom surface of the moving part. The slide groove is opened at the bottom of one side of the outer wall of the housing. A slider is slidably connected inside the slide groove.

[0009] It is worth noting that a forward and reverse motor is fixedly connected to one end of the top surface of the mounting housing. The output end of the forward and reverse motor rotates through the inner wall of the top surface of the mounting housing and is coaxially fixedly connected to a driving bevel gear that meshes with the driven bevel gear.

[0010] Furthermore, it should be noted that one end of the slide rod slides through the outer wall of the mounting shell away from the fixed block and is fixedly connected to a connecting block. The bottom surface of the connecting block is rotatably connected to a rotating shaft, and the bottom end of the rotating shaft is fixedly connected to the top surface of the outer shell.

[0011] In a preferred embodiment, the movable plate is threadedly engaged with the drive screw, and the output end of the drive motor is coaxially and fixedly connected to the outer wall of one end of the reciprocating screw.

[0012] In a preferred embodiment, one side of the outer wall of the scraper is in contact with the outer wall of the lens away from the outer shell, and the outer wall of the slider away from the groove is fixedly connected to one side of the outer wall of the scraper.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Through the action of the adjustment mechanism, the forward and reverse motor drives the active bevel gear to rotate, which in turn drives the driven bevel gear to rotate, thereby causing the drive screw to rotate and drive the moving plate to move. In turn, the moving plate pushes the slide rod to move the connecting block, thereby realizing the adjustment of the outer shell and the lens. The operation is simple, ensuring the use effect of the rearview mirror, improving the safety of the tractor in driving, and effectively avoiding the problem that the rearview mirror of the tractor is not easy to adapt to different types of aircraft.

[0015] 2. Through the action of the cleaning component, the drive motor drives the reciprocating screw to rotate, which causes the moving part to drive the scraper to clean the lens, so that the lens is in a clear state. This saves time and effort and prevents unclear lenses from affecting the safe driving of the tractor. It effectively avoids the problem that blurry rearview mirrors can easily affect the safe driving of the tractor. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Figures 1-4 As shown, this utility model provides a technical solution, including a vehicle body 1, a driver's cabin 2 is provided on one side of the top surface of the vehicle body 1, two symmetrically distributed fixing blocks 3 are fixedly connected to the top of the outer wall of one side of the driver's cabin 2, an adjustment mechanism 4 is provided on the outer wall of one end of the fixing block 3, and two outer shells 5 are installed in the driver's cabin 2 through the two sets of adjustment mechanisms 4. A lens 6 is embedded in the outer wall of one side of the outer shell 5, and a cleaning component 7 is provided on the top surface of the outer shell 5.

[0023] The adjustment mechanism 4 includes a mounting shell 41. One end of the outer wall of the mounting shell 41 is fixedly connected to one end of the outer wall of the fixing block 3. A drive screw 42 is rotatably connected between the inner walls of both ends of the mounting shell 41. A driven bevel gear 43 is fastened to one end of the outer surface of the drive screw 42. A guide rod 44 is fixedly connected between the inner walls of both ends of the mounting shell 41. A movable plate 45 is slidably sleeved on the outer surface of the guide rod 44. A slide rod 46 is fixedly connected to one end of the outer wall of the movable plate 45.

[0024] Further as Figure 4 As shown, it is worth noting that the cleaning component 7 includes two parallel bearing seats 71 and a slide groove 76. Both bearing seats 71 are fixedly connected to the top surface of the housing 5. A reciprocating screw 72 is rotatably connected between the two bearing seats 71. A drive motor 73 is fixedly connected to the outer wall of one end of one of the bearing seats 71. A moving part 74 is threadedly connected to the outer surface of the reciprocating screw 72. A scraper 75 is fixedly connected to one side of the bottom surface of the moving part 74. The slide groove 76 is opened at the bottom of one side of the outer wall of the housing 5. A slider 77 is slidably connected inside the slide groove 76.

[0025] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that a forward and reverse motor 8 is fixedly connected to one end of the top surface of the mounting housing 41. The output end of the forward and reverse motor 8 rotates through the inner wall of the top surface of the mounting housing 41 and is coaxially fixedly connected to a driving bevel gear 9 that meshes with the driven bevel gear 43.

[0026] Further as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the outer wall of one end of the slide rod 46 slides through the outer wall of the mounting shell 41 away from the fixed block 3 and is fixedly connected to the connecting block 10. The bottom surface of the connecting block 10 is rotatably connected to the rotating shaft 11, and the bottom end of the rotating shaft 11 is fixedly connected to the top surface of the outer shell 5.

[0027] Further as Figure 3 and Figure 4 As shown, it is worth noting that the movable plate 45 is threadedly engaged with the drive screw 42. Under the action of the thread, the rotation of the drive screw 42 causes the movable plate 45 to push the slide bar 46 to slide inside the mounting shell 41, thereby adjusting the outer shell 5. The output end of the drive motor 73 is coaxially and fixedly connected to the outer wall of one end of the reciprocating screw 72, so that the drive motor 73 can drive the reciprocating screw 72 to rotate, thereby causing the reciprocating screw 72 to drive the movable part 74 to drive the scraper 75 to scrape and clean the lens 6.

[0028] Further as Figure 4As shown, it is worth noting that one side of the outer wall of the scraper 75 is in contact with the side of the lens 6 away from the outer shell 5, which facilitates the removal of dust from the outer surface of the lens 6. The side of the slider 77 away from the slide groove 76 is fixedly connected to the side of the outer wall of the scraper 75. The sliding cooperation between the slide groove 76 and the slider 77 improves the stability of the scraper 75 when it moves.

[0029] In summary: When this device is in use, if it is necessary to adjust the rearview mirrors of the towing vehicle according to the specifications of the towing aircraft, the forward and reverse motor 8 is turned on to drive the active bevel gear 9 to rotate clockwise. Under meshing action, the active bevel gear 9 drives the driven bevel gear 43 to rotate, which in turn drives the drive screw 42 to rotate. Under the action of the thread, the rotating drive screw 42 drives the moving plate 45 to move along the direction of the guide rod 44. At this time, the moving plate 45 pushes the slide rod 46 to gradually slide out from the inside of the mounting shell 41. The slide rod 46 then pushes the connecting block 10 to move, thereby realizing the adjustment of the position of the outer shell 5 and the lens 6 installed on the outer shell 5. The position of the outer shell 5 is adjusted under the action of the forward and reverse motor 8. The two sets of adjustment mechanisms 4 are operated in sequence to adjust the two rearview mirrors. The operation is simple, allowing the rearview mirrors of the towing vehicle to be adapted to different types of aircraft, ensuring the use effect of the rearview mirrors, improving the safety of the towing vehicle during driving, and effectively avoiding the problem that the rearview mirrors of the towing vehicle are not easy to adapt to different types of aircraft.

[0030] When it is necessary to clean the dust on the rearview mirror of the tractor, the drive motor 73 is turned on to drive the reciprocating screw 72 to rotate. Under the action of the screw, and through the sliding cooperation of the slide groove 76 and the slider 77, the reciprocating screw 72 drives the moving part 74 to move back and forth. When the moving part 74 moves, it drives the scraper 75 to move synchronously. The scraper 75, which is in contact with the lens 6, removes the dust on the lens 6, so that the lens 6 is in a clear state. This saves time and effort and prevents the unclear lens 6 from affecting the safe driving of the tractor. It effectively avoids the problem that a blurry rearview mirror can easily affect the safe driving of the tractor.

[0031] The drive motor 73 and the forward and reverse motor 8 can be purchased from the market. The drive motor 73 and the forward and reverse motor 8 are equipped with power supplies. They are mature technologies in the field and have been fully disclosed. Therefore, they will not be described again in the specification.
