[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1, such as Figures 1-3 The present invention provides the following technical solution to address the problem of insufficient cushioning effect of vehicle luggage racks, which affects cargo safety: a cushioning mechanism is disclosed, comprising a base frame 1, with a guide plate 2 welded to the side of the base frame 1; a support frame 106 connected to the top of the base frame 1; a fixing block 101 fixedly connected to both the support frame 106 and the side of the base frame 1; a compression block 103 rotatably connected between two rotating blocks 102; two compression blocks 103 symmetrically connected about the base frame 1; a cushioning mechanism for reducing the impact of the luggage rack is provided on the side of the base frame 1; the cushioning mechanism includes a guide rod 104 that slides through the compression block 103; a damping spring is installed on the side of the compression block 103 near the guide rod 104; a telescopic block 105 is connected between the support frame 106 and the base frame 1; and four sets of cushioning mechanisms are symmetrically arranged on the side of the base frame 1.

[0027] After the luggage rack is installed on the roof of the vehicle, due to the bumps of the vehicle, the cargo on top of the base frame 1 will exert downward pressure on the base frame 1. This downward pressure can drive the support frame 106 to move downward. When the support frame 106 moves downward, it can drive the fixed block 101 to move. When the fixed block 101 moves, the rotating block 102 can rotate through the fixed block 101. At the same time, the fixed block 101 on the side of the base frame 1 will also drive the rotating block 102 to rotate. When the two rotating blocks 102 rotate, they can push the squeezing block 103 to move. When the squeezing block 103 moves, it can slide through the guide rod 104. When the squeezing block 103 slides, it will move relative to another set of symmetrical squeezing blocks 103. When the two squeezing blocks 103 slide, they can squeeze the damping spring. At the same time, when the support frame 106 moves downward, the telescopic block 105 will retract. The retraction of the telescopic block 105 can guide the downward movement of the support frame 106, and the downward movement of the support frame 106 can achieve a buffering effect through the damping spring, reducing the impact force generated by the luggage on the luggage rack when it bumps, and improving the protection effect of the cargo.

[0028] Example 2, as follows Figure 2 , Figure 4 , Figure 5 and Figure 6 The present invention provides the following technical solution to address the problem of insufficient loading capacity of the luggage rack: An extension mechanism is disclosed: An extension mechanism to increase the load-bearing capacity of the luggage rack is also provided inside the support frame 106. The extension mechanism includes a hidden groove 201 opened at the top of the support frame 106. Three sets of hidden grooves 201 are provided. A rotating rod 202 is rotatably connected inside the hidden groove 201. A rotating block 203 is fixed to the side of the rotating rod 202. The rotating block 203 rotates through the hidden groove 201. A nut 204 is threaded onto the surface of the rotating block 203. A sliding block 205 is rotatably connected to the top of the rotating rod 202. The sliding block 205 slides through the sliding groove 206. The sliding groove 206 is opened at the bottom of the extension frame 207. A telescopic rod 208 is connected to the bottom of the extension frame 207 near the bottom of the rotating rod 202. The telescopic rod 208 is installed on the top of the base frame 1 and moves through the support frame 106.

[0029] When the luggage rack needs to load more goods, the extension frame 207 can be pushed upwards, when the extension frame 207 is pushed, the inner wall of the sliding groove 206 can extrude the sliding block 205, when the sliding block 205 is extruded, the rotating rod 202 can be rotated upwards, the rotating rod 202 can rotate through the hidden groove 201 and the sliding block 205, when the rotating rod 202 rotates, the sliding block 205 can slide in the sliding groove 206, when the rotating rod 202 rotates, the rotating block 203 can rotate in the hidden groove 201, and in the process of rising, the extension frame 207 can pull the telescopic rod 208 to extend and guide, when the rotating rod 202 rotates to the highest position, the nut 204 can be moved to the end of the rotating block 203 to rotate, when the nut 204 rotates, the nut 204 can threadedly slide with the rotating block 203, when the nut 204 threadedly slides to the side of the bearing frame 106, the rotating rod 202 can be extruded and positioned, when the rotating rod 202 is positioned, the extension frame 207 can be positioned, at this time, the extension frame 207 can increase the frame height of the base frame 1, when the frame height increases, more goods can be loaded, and the loading capacity of the luggage rack is improved.
