[0043] See also Figure 1 , Figure 2 ,and Figure 3 An embodiment of the adjustable rear shelf of the present invention is arranged on a Figure 1On a frame 11 of the straddle-type vehicle 1 shown, the adjustable rear rack includes a fixed seat 2, two rail members 3 arranged on the fixed seat 2 at intervals from each other in the left-right direction, two limit posts 4 respectively passing through the rail members 3, a plurality of wheel members 5 arranged in the rail members 3 and in rolling contact with the rail members 3, and a movable seat 6 pivotally connected to the wheel members 5. The fixed seat 2 includes a bottom plate 21, and a seat plate 22 locked on the bottom plate 21 and located between the bottom plate 21 and the movable seat 6 in the up-down direction.

[0044] Each track member 3 is located between the bottom plate 21 and the seat plate 22 in the up-down direction, and the track member 3 can be fixed on the bottom plate 21 and / or the seat plate 22. The cross-section of the track member 3 is generally C-shaped, and includes two end walls 31 spaced apart from each other in the up-down direction and in contact with the corresponding wheel member 5, and a side wall 32 connected to the end walls 31 in the up-down direction and located on the inner side of the corresponding wheel member 5 in the left-right direction. The track member 3 adopts an integrated design, which is less likely to cause the gap to expand due to excessive load, and effectively improves stability. The end wall 31 and the side wall 32 cooperate to define a track space 33 extending in the front-to-back direction and used to accommodate the wheel members 5. The limiting column 4 passes through the end wall 31 and is inserted into the track space 33 to stop and limit the movement of the corresponding wheel member 5.

[0045] The cross-sectional area of ​​the movable seat 6 is generally in the shape of an inverted U, and has a support plate portion 61 parallel to the top surface of the seat plate 22, and two side stop portions 62 extending downward from the left and right ends of the support plate portions 61 and pivotally mounted on the wheel members 5. The support plate portion 61 blocks the upper part of the seat plate 22 in the vertical direction, and the side stop portions 62 block the outer sides of the track members 3 in the left and right directions. The above design enables the movable seat 6 to cover the fixed seat 2, the track members 3, and the wheel members 5, achieving the effect of waterproof and dustproof. In addition, since there are no other components on the outer sides of the side stop portions 62, the width of the support plate portion 61 can be designed completely according to the needs of use without being interfered by other mechanisms.

[0046] See also Figure 2 , Figure 3 ,and Figure 4 The user can pull the movable seat 6 backwards as needed, and the wheels 5 can roll in the track members 3 to make the movable seat 6 move as shown in FIG. Figure 4As shown, the fixed seat 2 extends backwards relative to the fixed seat 2, thereby increasing the overall load-bearing area. This adjustable design can freely adjust the required load-bearing area according to the items to be carried, greatly improving versatility and convenience. The use of the wheel members 5 for sliding also makes the process of pulling the movable seat 6 smoother. At the same time, the limit posts 4 can be used to limit the sliding distance to prevent the movable seat 6 from falling off due to excessive backward pulling. Regardless of the position of the movable seat 6, the track members 3 are always blocked by the seat plate 22 and the movable seat 6 and are not exposed to the outside, thereby achieving the effect of waterproofing and dustproofing and reducing the failure rate.

[0047] See also Figure 1 , Figure 5 ,and Figure 6 When the present embodiment is actually installed on the frame 11 of the straddle-type vehicle 1, the frame 11 has an extension surface 111 which is at the same height as the top surface of the support plate portion 61. The support plate portion 61 and the extension surface 111 of the same height allow objects to be stably placed on both at the same time. In addition, each wheel member 5 can also be as Figure 6 As shown, it includes a pivot 51 inserted into the corresponding side stop 62 along the left-right direction, and a bearing 52 set on the pivot 51 and in rolling contact with the end walls 31. The bearing 52 has a bushing 521 surrounding the pivot 51, and an outer edge 522 protruding radially outward from the outer edge of the bushing 521 and located between the end walls 31 and the side stop 62.

[0048] In summary, the present invention can adjust the bearing area according to the demand, and the design of the movable seat 6 covering the track members 3 and the fixed seat 2 can produce a waterproof and dustproof shielding effect, so the purpose of the present invention can be achieved.
