[0026] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the embodiments of the present invention are further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0027] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0028] The modular vehicle roof provided by the present invention comprises a roof body 1 and a deflector 7. Two side beams 2 are arranged at the lower ends of both sides of the roof body 1. Figure 2 and Figure 3 As shown, each side beam 2 is a concave corrugated steel plate, and the side beam 2 has at least a mounting surface in contact with the side wall of the vehicle body. The side beam 2 is connected to the side wall by a fastener so that the mounting surface is in close contact with the side wall. Specifically, for example, one of the connection positions between the side beam 2 and the side wall is Figure 2 and Figure 3 In the position indicated by a, the fastener can be a bolt and nut assembly. Figure 4 As shown, the air deflector 7 is detachably connected to the top cover body 1 through a connecting mechanism, and the air deflector 7 is configured to have a first state in which it completely covers the top of the side beam 2, and a second state in which it is separated from the side beam 2. When the air deflector 7 is in the first state, its outer side is flush with the outer side of the top cover body 1.

[0029] Compared with the prior art, the present invention eliminates the original rectangular installation hole of the top cover, so that the top cover body 1 is not easy to deform, and the installation structure of the top cover body 1 is not limited by the size of the installation hole. The present application redesigns the structure of the side beams 2 on both sides of the top cover, so that the outer surface of the side beams 2 is lower than the outer surface of the top cover body 1, and designs a lightweight, modular air deflector 7 on the outside of the side beams 2, so that the connection position between the top cover and the side wall and its fasteners are hidden in the inner space of the air deflector 7, hiding or eliminating the welding deformation on both sides of the top cover body 1, and the top cover body 1 and its air deflector 7 have a delicate appearance. After installation, the air deflector 7 can be opened and closed flexibly. When opened, the top cover body 1 can be easily installed or removed, and when closed, the external quality of the power vehicle can be optimized, which not only prevents dust and rain and snow from entering the inner space of the air deflector to affect the connection performance of the top cover, but also reduces air resistance when the power vehicle is running at high speed, and improves the aerodynamic performance of the power vehicle.

[0030] In some embodiments, a plurality of air deflectors 7 are correspondingly arranged above each side beam 2 along the vehicle length direction. Figure 4 As shown, three deflectors 7 are correspondingly arranged on one side beam 2, and the size of the deflectors 7 is convenient for a single person to take. The number of modular deflectors 7 can be increased or decreased to adapt to different lengths of the top cover body 1, thereby adapting to different lengths of power vehicles. The arrangement of the lightweight deflectors 7 allows one operator to independently install it, saving labor.

[0031] In some embodiments, at least two connection mechanisms are provided for each air deflector 7, and the at least two connection mechanisms are provided at intervals along the vehicle length direction to ensure the connection stability when the air deflector 7 is installed on the roof body 1. Each connection mechanism includes at least two connection holes 8 correspondingly provided on the air deflector 7 from top to bottom, and a plurality of connection seats provided on the side beam 2 and corresponding to the connection holes 8, each connection seat is provided with a connection bolt 5 for passing through the connection hole 8, and the end of the connection bolt 5 is detachably equipped with a locking nut. Specifically, as Figure 2 and Figure 4 As shown, each air deflector 7 has 6 connection holes 8, 3 in the upper row and 3 in the lower row. Accordingly, 18 mounting seats are provided on one side beam 2. The above structure is conducive to structural unification and also creates favorable conditions for the modularization of the air deflector 7. When the air deflector 7 is fixed by the connecting bolts 5 and the locking nuts, the connecting bolts 5 cooperate with one or two locking nuts to provide conventional anti-loosening for the air deflector 7, and can maintain a high self-locking reliability under dynamic load.

[0032] In some embodiments, Figure 5As shown, the side beam 2 includes a first side panel 201 and a second side panel 202 which are arranged at an angle, the first side panel 201 and the second side panel 202 are integrally formed, the first side panel 201 is on the upper side of the second side panel 202, and a connecting seat is installed at one end of the first side panel 201 and the second side panel 202 which are away from each other, wherein the connecting seat installed on the first side panel 201 is a mounting angle panel 4, the mounting angle panel 4 includes a first plane which is welded to the first side panel 201 and parallel to the top cover body 1, and a second plane which is welded to the first side panel 201 and arranged at an angle to the first plane, wherein one connecting bolt 5 is welded to the first plane and is perpendicular to the first plane, specifically, the nut of the connecting bolt 5 is welded to the first plane, and when the air deflector 7 is installed, the stud of the connecting bolt 5 passes through the connecting hole 8 in the upper row of the air deflector 7, and by making the connecting bolt 5 perpendicular to the first plane, the connecting bolt 5 can be made as perpendicular to the air deflector 7 as possible, thereby improving the connection reliability and stability of the air deflector 7. The connection seat installed on the second side plate 202 is a flat plate 6 connected to the end of the second side plate 202, the flat plate 6 is parallel to the top cover body 1, and one of the connection bolts 5 is welded on the flat plate 6 and is perpendicular to the flat plate 6. Specifically, Figure 5 As shown, the flat plate 6 is slightly lower than the top cover body 1, and its lower end extends to be flush with the bottom end of the top cover body 1. The nuts of the connecting bolts 5 thereon are welded on the second plane. When the air deflector 7 is installed, the studs of the connecting bolts 5 pass through the connecting holes 8 in the lower row of the air deflector 7. By making the connecting bolts 5 perpendicular to the second plane, the connecting bolts 5 can be made as perpendicular to the air deflector 7 as possible, thereby further improving the connection reliability and stability of the air deflector 7.

[0033] In some embodiments, Figure 2 As shown, end plates 9 are provided below both ends of the roof body 1 along the vehicle length direction, and the end plates 9 are used to seal both ends of the side beams 2 to prevent debris from entering the cavity between the air deflector 7 and the side beams 2 and to improve the structural strength of the roof.

[0034] In some embodiments, the modular vehicle roof also includes an opening and closing mechanism, which is disposed between the side beam 2 and the air deflector 7. The opening and closing mechanism is configured to cause the air deflector 7 to be suspended on the roof body 1 when the air deflector 7 is in the second state, rather than the air deflector 7 being completely separated from the roof body 1. The air deflector 7 can be disassembled and assembled as a whole with the roof body 1. The air deflector 7 and the roof body 1 with integrated connecting mechanism and opening and closing mechanism realize modular and standardized manufacturing of the product and improve the installation efficiency of the roof.

[0035] In some embodiments, Figures 6 to 9As shown, the opening and closing mechanism includes a guide plate 10, a mounting bracket 11, a curved plate 12, a first sliding assembly 13 and a second sliding assembly 14. The guide plate 10 is mounted on the inner side of the air deflector 7, preferably by welding, and a first slideway 16 is provided on the guide plate 10, which runs through the vehicle length direction and extends along the height direction of the air deflector 7. The mounting bracket 11 is mounted on the outer side of the side beam 2, and a first positioning hole 15 is provided on the mounting bracket 11. Fig.14 and Fig.17 As shown, the curved plate 12 includes a first straight plate and a second straight plate that are integrally formed and arranged at an angle. Specifically, the angle between the first straight plate and the second straight plate is an obtuse angle, and the corner of the curved plate 12 is close to the side beam 2. A second positioning hole 17 is provided at one end of the first straight plate away from the second straight plate, and a second slideway 18 that runs through the vehicle length direction is provided on the second straight plate along its length direction. The first sliding component 13 passes through the first slideway 16 and the first positioning hole 15, that is, the first sliding component 13 can rotate and slide along the first slideway 16 under the limitation of the first positioning hole 15. The second sliding component 14 passes through the second slideway 18 and the second positioning hole 17, that is, the second sliding component 14 can rotate and slide along the second slideway 18 under the limitation of the second positioning hole 17.

[0036] When removing the air deflector 7, first unscrew each locking bolt on the outside of the air deflector 7, manually move the air deflector 7 to separate it from the top cover body 1, and pull the air deflector 7 outward and downward. During this process, the first sliding component 13 rotates under the limit of the first positioning hole 15 and slides along the first slide 16, and the second sliding component 14 rotates under the limit of the second positioning hole 17 and slides along the second slide 18. Then, the air deflector 7 is released, and the air deflector 7 can be suspended at the side lower part of the top cover body 1 under the action of the opening and closing mechanism. The above structure fully applies the modular design concept. The air deflector 7 and the top cover body 1 are opened and closed by the opening and closing mechanism. This function creates favorable conditions for removing the top cover without removing the air deflector 7.

[0037] In some embodiments, Fig.13 As shown, the first sliding assembly 13 includes a rod cap 19, a sliding rod 20 and a threaded rod 21 which are coaxially arranged and have successively decreasing diameters. The sliding rod 20 is used to pass through the first positioning hole 15 and the first slideway 16, and is clearance-matched with the first positioning hole 15 and the first slideway 16. Specifically, a first step h1 is formed between the rod cap 19 and the sliding rod 20, and a second step h2 is formed between the sliding rod 20 and the threaded rod 21. The sliding rod 20 passes through the first slideway 16 after passing through the first positioning hole 15, and the guide plate 10 is limited between h1 and h2. A flat washer 30, a spring washer 31 and a nut 32 are sequentially arranged on the threaded rod 21 to prevent the sliding rod 20 from falling off. A slot 22 is arranged at the end of the rod cap 19, and the fixing and matching of the nut 32 is facilitated by the cooperation of a tool such as a screwdriver with the slot 22.

[0038] In some embodiments, Figures 10 to 13 As shown, the second sliding assembly 14 has the same structure as the first sliding assembly 13, and the installation direction is opposite, that is, the mounting support 11 and the guide plate 10 are respectively located on the left and right sides of the curved plate 12. The sliding rod 20 of the second sliding assembly 14 is used to pass through the second positioning hole 17 and the second slideway 18, and is clearance-matched with the second positioning hole 17 and the second slideway 18. The sliding rod 20 of the second sliding assembly 14 passes through the second slideway 18 and then passes through the second positioning hole 17, and the mounting support 11 is limited between h1 and h2 of the sliding rod 20.

[0039] In some embodiments, Figure 5 and Fig.16 As shown, the mounting bracket 11 includes an angle plate 23 respectively welded on the first side plate 201 and the second side plate 202, and a rib plate 24 connecting the two ends of the angle plate 23. The bottom surface of the angle plate 23 is in contact with the first side plate 201 and the second side plate 202, and the two have the same length. The second positioning hole 17 is arranged in the middle of the rib plate 24, and the second positioning hole 17 passes through in the vehicle length direction to facilitate the positioning of the second sliding component.

[0040] In some embodiments, Fig.15 As shown, each air deflector 7 is provided with two opening and closing mechanisms, and the two opening and closing mechanisms are symmetrically distributed at both ends of the air deflector 7 to enhance the connection stability of the air deflector 7 and improve the strength of the top cover.

[0041] In some embodiments, Figure 6 As shown, both upper and lower ends of the air deflector 7 are provided with seamless return bends 25 bent inwardly to improve the longitudinal rigidity of the air deflector 7. A plurality of reinforcing plates are arranged at intervals along the vehicle length direction between the two seamless return bends 25 to further enhance the strength of the air deflector 7.

[0042] In some embodiments, Figure 6 As shown, the reinforcing plates on the air deflector 7 at least include a first reinforcing plate 26 disposed in the middle of the air deflector 7 and a plurality of second reinforcing plates 27 distributed at both ends of the air deflector 7, and the guide plate 10 of each opening and closing mechanism is welded to the side of a second reinforcing plate 27 located at the end. Figure 6 As shown, there are four second reinforcing plates 27, two of which are close to the left end of the air deflector 7, and the other two are close to the right end of the air deflector 7. The guide plate 10 on the left is butt-welded to the left side of the second reinforcing plate 27 from the left by carbon steel laser welding, and the guide plate 10 on the right is butt-welded to the right side of the second reinforcing plate 27 from the right by carbon steel laser welding.

[0043] In some embodiments, Figure 6As shown, a plurality of mounting blocks 3 corresponding to the connecting bolts 5 are welded on the end face of each seamless return bend 25, and mounting holes for the connecting bolts 5 to pass through are provided on the mounting blocks 3, so as to facilitate the tight connection between the connecting bolts 5 and the air deflector 7 and avoid the air deflector 7 being damaged due to excessive local force.

[0044] In some embodiments, a hand-pull groove 28 is provided at the lower edge of the deflector 7, and the hand-pull groove 28 is connected to the internal space of the deflector 7 to form a drainage channel, and a hand-pull plate 29 is provided above the groove edge of the hand-pull groove 28. Figure 6 and Figure 7 As shown, a long strip g is cut off on the left and right sides of the lower edge of the air deflector 7, and the cut-off part forms a hand-drawing groove 28 just large enough for fingers to penetrate, and a hand-grip plate 29 is welded above the hand-grip groove 28 to improve the safety of the operator. This technical solution not only realizes the hand-grip function of disassembling and assembling the air deflector 7 without destroying the overall appearance of the air deflector 7, preventing the thin plate from causing harm to the operator, but also improves the edge strength of the air deflector 7, and reserves a drainage channel for the inner cavity of the air deflector 7, so as to facilitate the discharge of liquid entering the cavity between the air deflector 7 and the side beam 2.
