All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0043] Embodiment 1:

[0044] As Figures 1-4 shown, an embodiment of the present utility model provides a fairing, including a first deflector 1, a second deflector 2, a protective frame 3 and a connecting assembly;

[0045] The first deflector 1 is used to be mounted on the mounting bracket of the electric vehicle, and the first deflector 1 is connected to the mounting bracket of the electric vehicle by bolts;

[0046] The second deflector 2 is disposed on a side of the first deflector 1 away from the mounting bracket of the electric vehicle, and the first deflector 1 and the second deflector 2 are detachably connected by at least one connecting assembly;

[0047] The protective frame 3 is fixedly connected to a side of the second deflector 2 facing the first deflector 1, and the protective frame 3 is used to cover the bolts connecting the first deflector 1 and the mounting bracket.

[0048] By providing the second deflector 2 on one side of the first deflector 1 and mounting the protective frame 3 on the side of the second deflector 2 facing the first deflector 1, the bolts can be covered, so that the bolts are not exposed, and thus it is not easy to rust. The second deflector 2 is detachably connected by the connecting assembly, which is convenient for disassembling and assembling the bolts, more convenient during the maintenance of the electric vehicle, and more beautiful because the bolts are covered.

[0049] Preferably, the second deflector 2 and the protective frame 3 are integrally formed.

[0050] According to an embodiment of the present invention, multiple sets of connecting components are provided.

[0051] By providing multiple sets of connecting components, the retention effect of the first deflector plate 1 and the second deflector plate 2 can be better. Preferably, four sets of connecting components are provided.

[0052] According to an embodiment of the present invention, as Figure 2 shown, the connecting component includes a first elastic member 4 and an insertion plate 5. A first through hole 101 is formed in the first deflector plate 1. The first elastic member 4 is inserted into the first through hole 101 along a first direction. The first elastic member 4 has a receiving cavity 401. One end of the insertion plate 5 is connected to the surface of the second deflector plate 2 facing the first deflector plate 1, and the other end of the insertion plate 5 is installed in the receiving cavity 401;

[0053] When the first elastic member 4 is in a first state, the first elastic member 4 is caught by the first through hole 101, so that the first elastic member 4 cannot withdraw from the first through hole 101;

[0054] When the first elastic member 4 is in a second state, the first elastic member 4 can withdraw from the first through hole 101 along a second direction;

[0055] The first direction and the second direction are two directions opposite to each other. The first direction is the direction from the second deflector plate 2 to the first deflector plate 1.

[0056] When multiple sets of connecting components are provided, the first elastic members 4 and the insertion plates 5 correspond one by one.

[0057] When installing the first deflector plate 1 and the second deflector plate 2, by connecting the insertion plate 5 and the first elastic member 4, and then inserting the first elastic member 4 into the first through hole 101. During the insertion process of the first elastic member 4, it is in the second state. When the first elastic member 4 is inserted in place, the first elastic member 4 is in the first state and is caught by the first through hole 101, so that the first elastic member 4 cannot withdraw from the first through hole 101.

[0058] It should be noted that when the first elastic member 4 is in the second state, the first elastic member 4 undergoes elastic deformation, the receiving cavity 401 decreases, and the two ends of the first elastic member 4 approach each other, so that it can smoothly enter the first through hole 101.

[0059] According to an embodiment of the present invention, as Figure 4 shown, the first elastic member 4 includes a connecting plate 402 and two elastic plates;

[0060] The gap between the two elastic plates forms the receiving cavity 401;

[0061] Each elastic plate includes a first plate body 403, a second plate body 404, and a stop block 405 that are connected in sequence;

[0062] One end of the two first plates 403 away from the second plate 404 is connected to two sides of the connecting plate 402 respectively;

[0063] A first angle is formed between the first plate body 403 and the second plate body 404, and the first angle is an obtuse angle;

[0064] Along the direction from the first plate body 403 to the second plate body 404 , the distance between the two first plate bodies 403 gradually increases.

[0065] When the first elastic member 4 is in the first state, the second plate body 404 and the protective frame 3 cooperate to clamp the first guide plate 1, thereby achieving the retention of the first guide plate 1 and the second guide plate 2. The two second plate bodies 404 are provided with a clearance groove on one side away from each other, and the two opposite side walls of the first through hole 101 enter the clearance groove and fit with the bottom wall of the clearance groove, so that the retention effect is better.

[0066] When the first elastic member 4 is in the second state, the two elastic plates are close to each other so that the distance between the two elastic plates is smaller than the width of the first through hole 101, so that the two elastic plates can be inserted into the first through hole 101, and the accommodating cavity 401 is reduced.

[0067] Furthermore, the plug plate 5 is fixedly connected to the second guide plate 2 via a mounting block, and a reinforcing plate is fixedly connected around the mounting block to enhance the strength of the mounting block.

[0068] Preferably, the plug plate 5, the second guide plate 2, the mounting block and the reinforcing plate are integrally injection molded.

[0069] Optionally, the plug plate 5, the second guide plate 2 and the mounting block are all made of stainless steel and are connected by welding.

[0070] According to one embodiment of the utility model, Figure 4 As shown, the connection assembly includes two elastic blocks 6;

[0071] The two elastic plates are provided with a clearance hole connected to the accommodating cavity 401, and each clearance hole is provided with an elastic block 6, and each elastic block 6 is fixedly connected to the elastic plate at one side away from the connecting plate 402;

[0072] The two elastic blocks 6 have a protrusion 601 on one side opposite to the other.

[0073] The plug board 5 is provided with a second through hole 501;

[0074] The two protrusions 601 are inserted into the second through holes 501 to limit the first elastic member 4 from being separated from the plug board 5 .

[0075] It should be noted that when the plug board 5 is inserted into the accommodation cavity 401 and is inserted in place, the two protruding parts 601 are inserted into the second through hole 501.

[0076] According to an embodiment of the present invention, one side of the two elastic blocks 6 close to the connecting plate 402 has a limiting part 602;

[0077] A limiting groove 406 is formed on the surface of the connecting plate 402 close to the elastic block 6. The limiting groove 406 is used to limit the first elastic member 4 from moving along the third direction on the plug board 5;

[0078] The two limiting parts 602 cooperate to limit the elastic block 6 from moving along the third direction on the plug board 5.

[0079] According to an embodiment of the present invention, limiting plates 7 are symmetrically and fixedly connected to both sides of the plug board 5. The two limiting plates 7 cooperate to limit the first elastic member 4 from moving along the fourth direction on the plug board 5. The fourth direction is the same as the width direction of the plug board 5, and the length direction of the plug board 5 is the same as the first direction;

[0080] The first direction, the third direction, and the fourth direction are perpendicular to each other.

[0081] Furthermore, the plug board 5 and the first elastic member 4 can be detachably connected. During the process of inserting the plug board 5 into the accommodation cavity 401, the limiting plates 7 on both sides of the plug board 5 cooperate to limit the first elastic member 4 from moving along the fourth direction on the plug board 5. The plug board 5 pushes the two elastic blocks 6 away from each other. When the plug board 5 is inserted in place, at this time, one end of the plug board 5 enters the limiting groove 406. The limiting groove 406 can limit the first elastic member 4 from moving along the third direction on the plug board 5. The two protruding parts 601 enter the second through hole 501, so as to further limit the first elastic member 4 from detaching from the plug board 5. When the two protruding parts 601 enter the second through hole 501, the surfaces of the two limiting parts 602 close to each other contact the two opposite surfaces of the plug board 5. The two limiting parts 602 and the two protruding parts 601 cooperate to further limit the first elastic member 4 from detaching from the plug board 5 and being basically unable to move along the second direction.

[0082] The distance from the limiting groove 406 to the protruding part 601 is adapted to the distance from the end of the plug board 5 entering the limiting groove 406 to the second through hole 501.

[0083] Certainly, in this embodiment, the insertion plate 5 and the first elastic member 4 can also be detachably connected in other forms. For example, a round hole is opened on one side of the limiting groove 406 of the connecting plate 402, and the limiting groove 406 communicates with the round hole. A threaded groove is opened at one end of the insertion plate 5 away from the second flow guiding plate 2. After the locking bolt passes through the round hole, it is screwed with the threaded groove to fix the insertion plate 5 and the first elastic member 4. Its purpose does not deviate from the design concept of the present invention. Therefore, it should belong to the protection scope of the present invention.

[0084] According to an embodiment of the present invention, as Figure 3 shown, the first flow guiding plate 1 includes a main board and two side boards. The two side boards are respectively fixedly connected to one side of the main board, and a second included angle is formed between the side board and the main board, and the second included angle is an obtuse angle.

[0085] The second flow guiding plate 2 has the same structure as the first flow guiding plate 1, and the second flow guiding plate 2 is parallel to the first flow guiding plate 1. The size of the second flow guiding plate 2 is smaller than the size of the first flow guiding plate 1.

[0086] In this embodiment, a first annular groove is opened on the side of the protection frame 3 away from the second flow guiding plate 2, and a rubber strip is installed in the annular groove. A second annular groove is opened on the side of the first flow guiding plate 1 close to the second flow guiding plate 2. The first annular groove and the second annular groove correspond to each other, so that part of the rubber strip enters the first annular groove and the other part enters the second annular groove, enhancing the sealing performance and further protecting the bolts from rusting.

[0087] Specifically, when installing the flow guiding cover, first connect the first flow guiding plate 1 to the mounting frame of the electric vehicle through a plurality of bolts, insert the insertion plate 5 into the first elastic member 4, then install the first elastic member 4 on the second flow guiding plate 2, and then insert the first elastic member 4 into the first through hole 101 of the first flow guiding plate 1. At this time, the protection frame 3 and the second flow guiding plate 2 can cover the bolts, completing the protection of the bolts, reducing the occurrence of rust, and improving the aesthetic degree.

[0088] Embodiment Two:

[0089] As Figures 5-6 shown, an electric vehicle includes a flow guiding cover, and also includes a second elastic member and a mounting frame. The second elastic member cooperates with the mounting frame to limit the first flow guiding plate 1 on the mounting frame.

[0090] A second elastic member is fixedly connected to the mounting frame, and a third through hole 102 is opened on the first flow guiding plate 1.

[0091] When the second elastic member is inserted in place, the second elastic member cannot exit from the third through hole 102 along the second direction.

[0092] The second elastic member includes an insertion block. A fourth through hole is formed in the insertion block, and an elastic dial is installed in the fourth through hole. The elastic dial protrudes from the insertion block. When the second elastic member is inserted into the third through hole 102, the elastic dial is squeezed and completely enters the fourth through hole. When the elastic dial completely passes through the third through hole 102, the elastic dial resets. The elastic dial and the mounting plate act together to clamp the first flow guiding plate 1 between the elastic dial and the mounting plate, playing a role in positioning and pre-assembly. Then, the first flow guiding plate 1 is fixed by a plurality of bolts, which is more rapid and convenient, and there is no need for workers to hold the first flow guiding plate 1 by hand to install the bolts.

[0093] When the first flow guiding plate 1 needs to be disassembled, first remove the second flow guiding plate 2, then remove the plurality of bolts, and finally manually press the elastic dial into the fourth through hole to remove the first flow guiding plate 1.
