Specific embodiments

[0034] The present utility model will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model, and cannot be used to limit the protection scope of the present utility model.

[0035] Embodiment 1

[0036] Such as Figures 1 to 17 As shown, a top fairing bracket for a commercial vehicle includes: a mounting hinge 2 for hinging the front part of the top fairing 1 to the top of the commercial vehicle body, and a number of first adjustable components and second adjustable components for keeping the height of the rear edge of the top fairing 1 relatively consistent with the height of the top of the rear compartment of the commercial vehicle; one end of the first adjustable component is connected to the side part of the top fairing 1, and the other end is connected to the top of the commercial vehicle body; one end of the second adjustable component is connected to the rear part of the top fairing 1, and the other end is connected to the top of the commercial vehicle body. The first adjustable component and the second adjustable component assemble the top fairing 1 to different heights, thereby ensuring that the height of the rear edge of the top fairing 1 is relatively consistent with the height of the top of the rear compartment of the commercial vehicle, thereby improving the fuel economy of the commercial vehicle.

[0037] Such as Figure 3 As shown, the front part of the top fairing 1 is provided with a front mounting base 11, the rear part is provided with a rear mounting base 12, and the rear part is also provided with a horizontal brace 13.

[0038] One end of the mounting hinge 2 is connected to the top of the commercial vehicle body, and the other end is connected to the front mounting base 11 provided on the front part of the top fairing 1.

[0039] The first adjustable component includes a side mounting bracket 3 for mounting on the top of the commercial vehicle body, and a side connection bracket 4 with one end mounted on the side mounting bracket 3; the other end of the side connection bracket 4 is hinged to the horizontal brace 13 provided on the top fairing 1 through a mounting hoop bracket 7.

[0040] The second adjustable component is structurally divided into upper and lower parts, namely an upper mounting seat 51 for connecting with a rear mounting base 12 arranged on the top fairing 1, and a lower mounting seat 52 hinged to the upper mounting seat 51 through a pin shaft 53; the lower mounting seat 52 is connected to the top of the commercial vehicle body; the upper mounting seat 51 and the lower mounting seat 52 can rotate around the axis of the pin shaft 53. During the process of assembling and connecting the rear mounting base 12 and the upper mounting seat 51 through bolts, the upper mounting seat 51 rotates and adjusts around the axis of the pin shaft 53, so as to ensure the fitting and matching of the mounting surfaces and mounting holes of the rear mounting base 12 and the upper mounting seat 51.

[0041] The top fairing 1 is mounted on the top of the commercial vehicle body through the commercial vehicle top fairing bracket described in the present utility model, as Figure 4 shown.

[0042] Such as Figure 5 shown, first, the side mounting bracket 3 is assembled to the top of the commercial vehicle body through bolts.

[0043] Such as Figure 6 、 Figure 7 shown, the second adjustable component is assembled to the top of the commercial vehicle body through bolts.

[0044] Such as Figure 8 shown, several groups of second mounting holes 521 with different heights are arranged on the lower mounting seat 52 of the second adjustable component ( Figure 8 in which N21 represents the first group of second mounting holes 521, N22 represents the second group of second mounting holes 521, and N23 represents the third group of second mounting holes 521), and the lower mounting seat 52 is connected to the top of the commercial vehicle body through the second mounting holes 521 with set heights, so as to support the rear part of the top fairing 1 to be kept at a set height; that is, when different second mounting holes 521 on the lower mounting seat 52 are assembled with the top of the commercial vehicle body through bolts, the second adjustable component can be assembled to different heights.

[0045] The second adjustable component further includes a rear connecting bracket 6, one end of the rear connecting bracket 6 is connected to the lower mounting seat 52, and the other end is connected to the top of the commercial vehicle body. Such as Figure 9 shown, the front and rear ends of the rear connecting bracket 6 are respectively connected to the lower mounting seat 52 and the top of the commercial vehicle body through bolts, which plays a role in supporting and strengthening the second adjustable component.

[0046] Several groups of third mounting holes 522 for connecting the rear connecting bracket 6 are arranged on the lower mounting seat 52. The number of groups of the third mounting holes 522 is the same as that of the second mounting holes 521, and the height difference between different groups of mounting holes is also the same, that is, the distance between adjacent two groups of second mounting holes and the distance between adjacent two groups of third mounting holes correspond one by one.

[0047] Such asFigures 10 to 13 As shown, first, one end of the mounting hinge 2 is assembled to the front mounting base 11 at the front of the top fairing 1 through bolts; then, the other end of the mounting hinge 2 and the entire top fairing 1 are assembled to the top of the commercial vehicle body through bolts. The top fairing 1 can rotate about the axis of the mounting hinge 2. Then, the rear mounting base 12 provided at the rear of the top fairing 1 is assembled and connected to the upper mounting seat 51.

[0048] During the process of assembling and connecting the rear mounting base 12 to the upper mounting seat 51 through bolts, the upper mounting seat 51 rotates and adjusts about the axis of the pin shaft 53, so as to ensure the fitting and matching of the mounting surfaces and mounting holes of the rear mounting base 12 and the upper mounting seat 51.

[0049] As Figure 14 shown, the side connection bracket 4 is assembled to the side mounting bracket 3 through bolts and nuts.

[0050] The side connection bracket 4 is provided with several groups of first mounting holes 41 with different heights. The side connection bracket 4 is connected to the side mounting bracket 3 through the first mounting holes 41 with a set height, and is used to support the side part of the top fairing 1 to be maintained at a set height. When assembling different first mounting holes 41 on the side connection bracket 4 through bolts, the side connection bracket 4 can be assembled to different heights. Moreover, the number of groups of the first mounting holes 41 is the same as that of the second mounting holes 521, and the height differences between different groups of mounting holes are also the same. As Figure 15 shown ( Figure 15 in the figure, N11 represents the first group of first mounting holes 41, N12 represents the second group of first mounting holes 41, and N13 represents the third group of first mounting holes 41). When assembling, it is necessary to determine the height of the top fairing 1 according to the height of the box top of the rear compartment of the commercial vehicle, and then determine which group of mounting holes with a set height in the first mounting holes 41 and the second mounting holes 521 need to be assembled.

[0051] The mounting hoop bracket 7 is clamped on the transverse brace 13 at the rear of the top fairing 1. Further, the side connection bracket 4 and the mounting hoop bracket 7 are assembled and connected through bolts and nuts. As Figure 16 shown.

[0052] When the mounting hoop bracket 7 is clamped on the transverse brace 13, the mounting hoop bracket 7 can rotate about the axis of the transverse brace 13. During the process of assembling and connecting the side connection bracket 4 and the mounting hoop bracket 7 through bolts and nuts, the mounting hoop bracket 7 rotates and adjusts about the axis of the transverse brace 13, so as to ensure the fitting and matching of the mounting surfaces and mounting holes of the side connection bracket 4 and the mounting hoop bracket 7.

[0053] In the present utility model, the side connection bracket 4 and the lower mounting seat 52 have multiple groups of mounting holes with different heights. When assembling the side connection bracket 4 and the lower mounting seat 52 through bolts at different mounting holes, the side connection bracket 4 and the lower mounting seat 52 can be assembled to different heights, thereby ensuring that the top fairing 1 is assembled to the same height as the top of the rear compartment of the commercial vehicle, maximizing the wind resistance reduction performance of the top fairing, and thus improving the fuel economy of the commercial vehicle. At the same time, the commercial vehicle top fairing bracket of the present utility model has the characteristics of simple structure, light weight, low production and manufacturing cost, and high reliability.
