example one
Referring to fig. 1 to 3, an embodiment of the present application discloses a recessed chassis, which includes a connecting portion 200 and two sidewalls 100. The concave underframe can be applied to container transportation equipment.
The side walls 100 are base members of the concave bottom frame, the side walls 100 can provide mounting bases for at least part of other components of the concave bottom frame, the two side walls 100 are arranged oppositely, the connecting portion 200 is arranged between the two side walls 100, and the connecting portion 200 is connected with the two side walls 100, so that the two side walls 100 are fixed to each other through the connecting portion 200 to be stable.
When the container is placed on the concave bottom frame, the container is positioned between the two side walls 100, so that the two side walls 100 can limit the container at two sides of the container to prevent the container from shaking in the direction from one side wall 100 to the other side wall 100. Therefore, in order to further limit the container by the side wall 100 to keep the container stable, the height of the side wall 100 can be set to match the height of the container
The sidewall 100 specifically includes an upper side beam 110, a lower side beam 120, and a pillar 130, wherein two ends of the pillar 130 are respectively connected to the upper side beam 110 and the lower side beam 120. Specifically, one end of the pillar 130 is connected to the lower side member 120, and the other end of the pillar 130 is supported by the upper side member 110, so that the upper side member 110 and the lower side member 120 are fixed. By arranging a certain distance between the upper side beam 110 and the lower side beam 120 and connecting the upper side beam 110 and the lower side beam 120 through the upright column 130, the side wall 100 can have a certain height, and meanwhile, the using amount of the side wall 100 can be saved, so that the preparation cost of the concave underframe of the application is lower.
One end of the upright column 130 and the upper side beam 110 can be connected in a hinged manner, so that a certain rotation allowance is formed between the upright column 130 and the upper side beam 110, a certain rotation freedom degree is formed between the upright column 130 and the upper side beam 110, and after the upright column 130 and the upper side beam 110 are subjected to external force, the external force applied to the upright column 130 and the upper side beam 110 can be partially released through relative rotation between the upright column 130 and the upper side beam, so that the upright column 130 and the upper side beam 110 are prevented from being damaged after being subjected to external force for a long time.
The other end of the pillar 130 and the lower side sill 120 may also be connected in a hinged manner, so that a certain rotation margin is provided between the pillar 130 and the lower side sill 120, so that a certain degree of freedom of rotation is provided between the pillar 130 and the lower side sill 120, and the purpose of protecting the pillar 130 and the upper side sill 110 can also be achieved.
Meanwhile, since the upper and lower side members 110 and 120 are hinged to the pillar 130, the upper and lower side members 110 and 120 and the pillar 130 have rotational degrees of freedom, and thus the upper and lower side members 110 and 120 also have a certain rotational degree of freedom. Thus, when the joint of the upper side rail 110 and the pillar 130 is subject to an external force, the upper side rail 110 can rotate relative to the pillar 130, and the lower side rail 120 can also rotate relative to the pillar 130, so that the external force applied to the joint of the upper side rail 110 and the pillar 130 can be better released. Similarly, when the connection between the lower side rail 120 and the pillar 130 is subject to an external force, the lower side rail 120 can rotate relative to the pillar 130, and the upper side rail 110 can also rotate relative to the pillar 130, so that the external force applied to the connection between the lower side rail 120 and the pillar 130 can be better released.
In the concave underframe provided by the embodiment of the application, the upper side beam 110, the lower side beam 120 and the upright column 130 in the side wall 100 are connected in a hinged manner, so that a certain rotational degree of freedom is formed between the lower side beam 120 and the upright column 130, and a certain rotational degree of freedom is also formed between the upper side beam 110 and the upright column 130, so that when the side wall 100 is subjected to an external force, at least part of the external force can be released by the rotational degree of freedom among the upper side beam 110, the lower side beam 120 and the upright column 130, and the damage of the joint of the upper side beam 110, the lower side beam 120 and the upright column 130 due to long-term stress can be prevented.

In some embodiments, the two ends of the cross beam 210 may be hinged to the lower side beam 120, so that a certain rotation margin may be provided between the cross beam 210 and the lower side beam 120, and thus, a certain degree of freedom of rotation may be provided between the cross beam 210 and the lower side beam 120, and after the cross beam 210 and the lower side beam 120 are subjected to an external force, the cross beam 210 and the lower side beam 120 may release a part of the external force applied to them through a relative rotation therebetween, thereby preventing the cross beam 210 and the lower side beam 120 from being damaged after being subjected to the external force for a long time.
Specifically, when the two side walls 100 are subjected to a compressive force or a traction force, an interaction force exists between the side walls 100 and the cross beams 210, and the cross beams 210 are hinged to the lower side beams 120, so that the interaction force between the side walls 100 and the cross beams 210 is released through the rotational freedom degree between the side walls 100 and the cross beams 210.

Specifically, the first hinge seat 300 and the second hinge seat 400 may have the same structure, and the difference between the first hinge seat 300 and the second hinge seat is that the first hinge seat 300 may be fixed to the upper side beam 110 by welding, so that the first hinge seat 300 and the upper side beam 110 may be connected stably and reliably, and meanwhile, it is not necessary to provide a fixing structure, such as a fixing hole and a fixing clip groove, on the upper side beam 110, which is specially used for fixing the first hinge seat 300, so that the structural integrity of the upper side beam 110 is better, and the structural stability of the upper side beam 110 is better.
The second hinge base 400 can also be fixed to the lower side member 120 by welding, so that the second hinge base 400 and the lower side member 120 can also have a stable and reliable connection effect.

In some embodiments, the present embodiment is further provided with a third hinge seat 500, and the cross beam 210 may be hinged with the lower side beam 120 through the third hinge seat 500. Specifically, the third hinge seats 500 are disposed on the lower side members 120 of the two side walls 100, and the third hinge seats 500 disposed on the two lower side members 120 are disposed opposite to each other, so that both ends of the cross member 210 can be respectively hinged to the third hinge seats 500 of the two lower side members 120, and the cross member 210 is hinged to the two lower side members 120. The third hinge base 500 may have the same structure as the first hinge base 300 and the second hinge base 400, so that the type of the parts of the female chassis according to the embodiment of the present invention may be reduced, and the production and maintenance may be facilitated.
