Modular passive carrying mechanical auxiliary mechanism

The modularized passive carrying mechanical auxiliary mechanism comprises a trunk module, a left leg part and a right leg part, the left leg part and the right leg part are mirror images of each other and are fixed to the two sides of the trunk module, and the trunk module, the left leg part and the right leg part each comprise a plurality of rigid elements and elastic elements which are connected with each other. The rigid elements of the trunk module are connected through the elastic elements to form a bearing structure of the trunk module and used for reducing supporting loads borne by the upper body of a user, the trunk module obtains the freedom degree during movement through the elastic elements, and the rigid elements of the left leg part and the right leg part reduce and transmit the supporting loads under the action of the elastic elements; the trunk module comprises a binding wearing module and a back spine module, the binding wearing module is connected with the back spine module, the back spine mo
