[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] The core of the present invention is to provide a fairing. Through the split design of the main fairing and the side fairings, combined with the hinge provided at the front end of the main fairing for connecting to the top of the cockpit, and a number of sets of height adjustment holes with different heights are provided inside the side fairings for combination with the main fairing, so as to meet the adjustment of the height and angle of the main fairing and be applicable to vehicles of different heights.

[0039] Another core of the present invention is to provide a vehicle including the above fairing, which has the same technical features, can solve the same problems and achieve the same purpose.

[0040] Please refer to Figures 1 - 7 , a fairing arranged on the top of the cockpit for guiding the airflow on the top of the cockpit, including:

[0041] The main fairing 1 is provided with a hinge 101 at the front end for hinging to the top of the cockpit, and fixing holes 102 for bolt assembly are respectively arranged on the flat surfaces at both ends;

[0042] The side fairings 2, two sets of side fairings 2 are respectively arranged on both sides of the main fairing 1, and a connecting plate 5 is fixedly arranged inside the side fairing 2. A number of sets of height adjustment holes 501 with different heights are arranged on the surface of the connecting plate 5, and the fixing holes 102 can be bolted to any one of the sets of height adjustment holes 501;

[0043] A hinge 101 is provided at the front end of the main fairing 1, and the main fairing 1 is hinged to the top of the cockpit through the hinge 101, so that the angle between the main fairing 1 and the cockpit is adjustable, changing the angle of the upper surface of the main fairing 1, and thus changing the airflow direction. At the same time, a structural design of separating the main fairing 1 and the side fairings 2 is adopted, and the side fairings 2 are used to support the sides of the main fairing 1, so as to ensure that the main fairing 1 has better stability after the angle is adjusted;

[0044] In some embodiments, a connecting plate 5 is provided on the inner wall of the side fairing 2, and a plurality of groups of height adjustment holes 501 with different heights are provided on the connecting plate 5 for bolt connection with the fixing holes 102 in the main fairing 1. The connecting plate 5 is directly welded or bolt-fixed to the side fairing 2, so that the height adjustment holes 501 not blocked by bolts are located between the side fairing 2 and the main fairing 1, thereby avoiding noise generated by external air flow passing through the unblocked height adjustment holes 501;

[0045] In some embodiments, other locking components, such as a multi-position snap component, are added between the side fairing 2 and the main fairing 1, and the locking position of the side fairing 2 and the main fairing 1 is changed by changing the locking position of the snap;

[0046] At the same time, the structural design of arranging the side fairing 2 on the side of the main fairing 1 can be used to shield the side gap generated after the angle adjustment of the main fairing 1 by the side fairing 2, avoiding noise generated when the air flow passes through the side gap of the main fairing 1;

[0047] At the same time, in some embodiments, a handle 103 is provided on the inner wall of the top of the rear end of the main fairing 1 to facilitate the operation of the main fairing 1;

[0048] During use, the operator holds the handle 103 and moves it up and down to change the angle and the rear-end height of the main fairing 1, so that the rear-end height of the main fairing 1 is flush with the rear vehicle body, changing the air flow direction at the top of the cockpit, avoiding the generation of air vortices between the cockpit and the vehicle body, and thus reducing noise. After the main fairing 1 is adjusted, bolts are passed through the fixing holes 102 and the corresponding height adjustment holes 501, and then tightened;

[0049] When setting the position of the height adjustment holes 501, they should be arranged in a circular array centered on the rotation axis of the hinge 101 to ensure that the fixing holes 102 and the corresponding height adjustment holes 501 have good coaxiality.

[0050] In some embodiments, as Figure 1 shown, a telescopic support rod 3 is further included. The two ends of the telescopic support rod 3 are respectively hinged to the upper edge of the arc surface of the main fairing 1 and the top of the cockpit, and are used to restrain the rotation of the main fairing 1 and the cockpit;

[0051] By adding the telescopic support rod 3, when the main fairing 1 is adjusted, it has a certain damping feeling, ensuring that the main fairing 1 has a certain position maintaining ability before the bolts in the fixing holes 102 are inserted, thereby facilitating the assembly of the bolts in the fixing holes 102 and the height adjustment holes 501.

[0052] In some embodiments, as Figure 1 and Figure 7As shown, a storage rack 4 is arranged in the space below the main fairing 1. The storage rack 4 is slidably installed on the top of the cockpit, and the sliding direction of the storage rack 4 is perpendicular to the rotation axis of the hinge 101;

[0053] By adding the storage rack 4 below the main fairing 1, the utilization rate of the space below the main fairing 1 is improved. Moreover, the storage rack 4 is slidably installed, enabling the storage rack 4 to slide back and forth, facilitating the access to the items inside the storage rack 4 and enhancing its practicality.

[0054] In some embodiments, as Figure 5 shown, the storage rack 4 includes a frame and a guide rail for slidably installing the frame on the top of the cockpit. The guide rail includes a first C-shaped plate 401 fixedly installed on the top of the cockpit and a second C-shaped plate 402 fixedly installed on the frame. The first C-shaped plate 401 and the second C-shaped plate 402 are coaxial and slidably nested with each other, and a fixed ear plate 408 for restricting the maximum relative displacement amount of the two is fixedly arranged at the end of the first C-shaped plate 401 or the second C-shaped plate 402;

[0055] The guide rail adopts a structural design in which the first C-shaped plate 401 and the second C-shaped plate 402 are nested with each other to ensure the smoothness during sliding. Moreover, a fixed ear plate 408 is added at the end of one set of C-shaped plates. When the other set of C-shaped plates slides to abut against the fixed ear plate 408, the relative sliding between the two stops, thereby determining the maximum relative sliding amount of the two, that is, determining the maximum sliding amount of the frame.

[0056] In some embodiments, the fixed ear plate 408 is fixedly arranged at the end of the first C-shaped plate 401 away from the hinge 101. The fixed ear plate 408 is provided with a through hole, and the second C-shaped plate 402 is provided with several groups of limit holes along the length direction. The through hole can be inserted into any one of the limit holes together with a limit pin to restrict the relative sliding between the first C-shaped plate 401 and the second C-shaped plate 402;

[0057] As Figure 5 shown, by setting the fixed ear plate 408 at the end of the first C-shaped plate 401, arranging a through hole in the fixed ear plate 408, and arranging several groups of limit holes along the length direction in the second C-shaped plate 402, when one group of limit holes in the second C-shaped plate 402 is coaxial with the through hole and a limit pin or bolt is inserted inside, the relative positions of the first C-shaped plate 401 and the second C-shaped plate 402 are limited, and the two no longer slide, that is, the position of the frame is fixed, which is mainly used to fix the storage rack 4 during the vehicle driving process.

[0058] In some embodiments, as Figure 6 shown, a first roller 403 is arranged in the inner cavity at the end of the first C-shaped plate 401 away from the hinge 101. The first roller 403 is in rolling contact with the inner cavity wall of the second C-shaped plate 402;

[0059] A second roller is provided in the inner cavity of the second C-shaped plate 402 near one end of the hinge 101, and the second roller is in rolling contact with the inner cavity wall of the first C-shaped plate 401;

[0060] By adding rollers at the ends of the C-shaped plates, the radial movement between the first C-shaped plate 401 and the second C-shaped plate 402 is reduced, thereby ensuring the straightness and smoothness during their sliding.

[0061] In some embodiments, as Figure 6 shown, a plurality of groups of through holes are provided in the first C-shaped plate 401 along the length direction, and a limit pin or a limit bolt is provided in any one of the through holes to limit the maximum displacement of the second roller;

[0062] By providing through holes in the first C-shaped plate 401 and providing limit pins or limit bolts in the through holes, the second roller is prevented from passing through this position, thereby restricting the maximum relative movement amount between the second C-shaped plate 402 and the first C-shaped plate 401 for use with the main flow deflector 1 with different front and rear lengths.

[0063] In some embodiments, as Figure 4 and Figure 5 shown, a fixed seat 404 is provided at one end of the top of the frame rack 4. A roller 405 is rotatably provided in the fixed seat 404. A binding rope 406 is wound inside the roller 405, and the free end of the binding rope 406 can be connected to a fixed hook 409 fixedly installed at the other end of the top of the rack 4;

[0064] A ratchet mechanism is provided between the roller 405 and the fixed seat 404;

[0065] By adding the roller 405 and the binding rope 406 wound inside it, combined with the fixed hook 409 at the other end of the rack 4, the binding rope 406 can bind the internal goods from the top of the rack 4 to prevent the goods from falling out. And a ratchet mechanism is added between the roller 405 and the fixed seat 404, so that when the roller 405 tightens the binding rope 406, it will not rotate in the reverse direction, which is convenient for applying a pre-tightening force to the binding rope 406. And when releasing, only the pawl of the ratchet mechanism needs to be rotated, and the roller 405 regains the ability to rotate in the reverse direction to realize the release of the binding rope 406. At the same time, for the convenience of the rotation of the roller 405, a rotation handle 407 is provided at the end of the roller 405 to facilitate the operator to hold or facilitate the connection of tools to promote the rotation of the roller 405.

[0066] In addition to the flow deflectors disclosed in the above various embodiments, the present invention also provides a vehicle including the above flow deflector. For the structures of other parts of the vehicle, please refer to the prior art and will not be elaborated herein.

[0067] In the present specification, the various embodiments are described in a progressive manner. Each embodiment focuses on the differences from other embodiments, and the same or similar parts among the various embodiments can be referred to each other.
