The invention relates to the technical field of vehicles, in particular to a support structure, a
trunk and a vehicle. The support structure comprises a first support, a second support and multiple connecting rod assemblies, each connecting rod
assembly comprises a first connecting rod and a second connecting rod which are rotationally connected, in each connecting rod
assembly, the end, away from the second connecting rod, of the first connecting rod is rotationally connected with the second support, and the end, away from the first connecting rod, of the second connecting rod is rotationally connected with the first support; the second support is movably connected with the first support, so that the connecting rod assemblies stretch out in the direction away from the first support or the second support to form a plurality of hook structures, or the connecting rod assemblies retract in the direction towards the first support or the second support. According to the support structure provided by the invention, through the movement of the first support or the second support, the connecting rod
assembly can extend out to form a plurality of hook structures, so that a plurality of articles can be hung, the space
utilization rate is increased, and the support structure can be retracted when not in use to save the storage space of the luggage case.
