Description

Technical Field

[0001] The utility model relates to the technical field of vehicle structures, in particular to an installation structure of a fairing back plate. Background Art

[0002] A fairing is an air guiding device installed on the top of the cab of a freight truck or a tractor truck. Its main function is to effectively reduce the air resistance of the truck when driving at high speed and reduce fuel consumption. When installing the fairing, the fairing back plate needs to be installed on the vehicle body first before the fairing can be installed.

[0003] However, most of the existing installation methods of fairing back plates are fixed. The fixed fairing back plate is installed on the cab roof, and the angle of the fairing cannot be changed after installation. When the height of the goods in the carriage is different, the effect that the fairing can achieve is also different. When the goods in the carriage are relatively high, the original angle of the fairing cannot effectively reduce the air resistance of the vehicle, thus wasting a large amount of kinetic energy. Therefore, we propose an installation structure of a fairing back plate. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art. Most of the existing installation methods of fairing back plates are fixed. The fixed fairing back plate is installed on the cab roof, and the angle of the fairing cannot be changed after installation. When the height of the goods in the carriage is different, the effect that the fairing can achieve is also different. When the goods in the carriage are relatively high, the original angle of the fairing cannot effectively reduce the air resistance of the vehicle, thus wasting a large amount of kinetic energy.

[0009] As a preferred solution of the present utility model, the slider is movably connected to the connecting rod, and the slider is slidably connected to the sliding groove.

[0010] The technical effect of adopting the above further solution is that: when the angle of the back plate needs to be adjusted, the electric cylinder drives the connecting rod to move upward, and the connecting rod is movably connected to the slider, which can make the electric cylinder jack up the back plate more conveniently, thereby changing the angle of the flow deflector.

[0011] As a preferred solution of the present utility model, the back plate is fixed to the two support frames by bolts, and threaded holes are respectively provided through the top ends of the back plate near the corners.

[0012] The technical effect of adopting the above further solution is that: the back plate is fixed to the support frame by bolts, which can make the installation of the back plate more stable, and the flow deflector can also be installed more conveniently through the threaded holes.

[0028] Example 1

[0029] As Figures 1-5 shown, the utility model provides a technical solution: a mounting structure for a fairing back plate, which includes a back plate 1. The back plate 1 can be replaced according to actual needs. Electric cylinders 2 are arranged near the left and right sides below the back plate 1. The electric cylinders 2 can rise or fall. First fixing members 3 are arranged at the tops of the two electric cylinders 2. First bearings 301 are arranged inside the first fixing members 3. A first rotating shaft 302 is arranged inside the first bearing 301. The first rotating shaft 302 can rotate within the first bearing 301. Connecting rods 4 are sleeved on the outer circumferential walls of the first rotating shafts 302. The connecting rods 4 can drive the first rotating shafts 302 to rotate. Support frames 5 are arranged at the bottom of the back plate 1 corresponding to the two connecting rods 4. The support frames 5 play a role in supporting the back plate 1. Sliding grooves 6 are opened at the bottoms of the two support frames 5. Sliders 7 are arranged inside the sliding grooves 6. The sliders 7 can slide inside the sliding grooves 6. Second bearings 8 are opened at the ends of the support frames 5 far from the sliding grooves 6. Second rotating shafts 801 are arranged inside the second bearings 8. The second rotating shafts 801 can rotate inside the second bearings 8. Second fixing members 9 are arranged at both ends of the second rotating shafts 801. Third bearings 901 are arranged corresponding to the second rotating shafts 801 on the four second fixing members 9. The second rotating shafts 801 can also rotate within the third bearings 901.

[0030] Example 2

[0031] As Figures 1-5 shown, the first rotating shaft 302 is rotationally connected to the first bearing 301, the second rotating shaft 801 is rotationally connected to the second bearing 8, and the second rotating shaft 801 is rotationally connected to the third bearing 901. The rotational connection between the rotating shaft and the bearing can make it more convenient to adjust the angle of the back plate 1. The slider 7 is movably connected to the connecting rod 4, and the slider 7 is slidably connected to the sliding groove 6. When the angle of the back plate 1 needs to be adjusted, the electric cylinder 2 drives the connecting rod 4 to move upward. The connecting rod 4 is movably connected to the slider 7, which can make it more convenient for the electric cylinder 2 to lift the back plate 1, thereby changing the angle of the fairing. The back plate 1 is fixed to the two support frames 5 by bolts. Threaded holes 101 are penetrated and opened near the corners at the top of the back plate 1. The back plate 1 is fixed to the support frame 5 by bolts, which can make the installation of the back plate 1 more stable. The fairing can also be more conveniently installed through the threaded holes 101. Buffer pads 201 are arranged on both sides of the connecting rod 4 at the tops of the two electric cylinders 2. The buffer pads 201 are made of rubber material. When the electric cylinder 2 drives the connecting rod 4 to move upward or downward, the buffer pads 201 can play a buffering role during the displacement of the connecting rod 4. The two electric cylinders 2 are both electrically connected to an external power supply.

[0032] The working process of the present utility model: When using an installation structure of a fairing back plate to change the angle of the fairing, first, the electric cylinder 2 is turned on. The electric cylinder 2 will drive the first fixing member 3 to rise or fall. At this time, the connecting rod 4 will rise or fall with the electric cylinder 2 through the first bearing 301 and the first rotating shaft 302. The connecting rod 4 will drive the slider 7 to slide inside the chute 6, so that the support frame 5 changes the angle through the second bearing 8, the second rotating shaft 801 and the third bearing 901, thereby changing the angle of the back plate 1. The back plate 1 will drive the angle of the fairing fixed to it by bolts. Compared with the existing installation structure of the fairing back plate, it can adapt to different cargo heights or carriage heights to obtain a smaller air resistance, save a large amount of kinetic energy, and improve the convenience and practicality of the installation structure of the fairing back plate when changing the angle of the fairing.

[0033] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
