The bonnet includes bonnet planking and bonnet inner panel, and bonnet inner panel and bonnet planking laminating each other connect and form the bonnet to the intensity of reinforcing bonnet. The engine cover inner plate is provided with a hollowed structure or a lightening hole so as to provide enough installation space for various components in the front cabin of the automobile, such as an engine, a transmission and the like.

However, the two support rods perpendicularly connected with the rack plate on the bearing plate in the related art are usually fixedly arranged on the bearing plate, so that the engine cover inner plate rack of the type can only meet the installation requirement of the engine cover inner plate with one specification and size.

Therefore, the embodiment of the utility model provides an inner plate work or material rest in bonnet, fig. 1 is the utility model provides a structural schematic diagram of inner plate work or material rest in bonnet, fig. 2 is the embodiment of the utility model provides a frame schematic diagram of an inner plate in bonnet. As shown in fig. 1 and 2, the bonnet inner plate holder includes: the frame comprises a bottom frame 10, a first side frame 11 vertically connected with the bottom frame 10, a plurality of adjusting cross rods 3 parallel to the bottom frame 10 and at least one pair of hanging rods 5.

Wherein, first side frame 11 includes: two first support rods 2 are arranged at intervals on a first side 101, and the first side 101 is a side where the bottom frame 10 is connected with the first side frame 11. One end of the adjusting cross rod 3 is connected with one of the two first supporting rods 2, and the other end of the adjusting cross rod 3 is connected with the other of the two first supporting rods 2, that is, the two ends of the adjusting cross rod 3 are respectively connected with the two first supporting rods 2. A plurality of adjusting crossbars 3 are arranged at intervals along the axial direction of the first supporting rod 2.

With reference to fig. 1 and 3, at least one pair of hanging rods 5 is located on the first side frame 11, at least one pair of hanging rods 5 is perpendicular to the adjusting cross rod 3 and parallel to the bottom frame 10, at least one hanging rod 5 of the at least one pair of hanging rods 5 is a movable hanging rod 50, the movable hanging rod 50 is connected with one of the adjusting cross rod 3 through a connecting assembly, the connecting assembly includes an adjusting plate 51 and a U-shaped bolt 56 (see fig. 3), the adjusting plate 51 is fixedly connected with one end of the movable hanging rod 50, the adjusting plate 51 is provided with at least two through holes 52 axially distributed along the first supporting rod 2, and the U-shaped bolt spans any one adjusting cross rod 3 and is connected with the adjusting plate 51 through the through hole 52.
