1. A test bed, comprising:
a support frame, used to bear a tested object;
a base, used to support the support frame;
at least one weighing assembly, fixed to the base and acquiring weight information of the tested object by sensing stress from the support frame;
wherein the weighing assembly comprises a sensor unit used to sense the stress from the support frame;
wherein the weighing assembly further comprises a force transmission apparatus used to transmit the stress from the support frame to the sensor unit, and the force transmission apparatus is mounted on an upper side of the sensor unit;
wherein the weighing assembly further comprises a fixing apparatus used to fix and support the sensor unit; the fixing apparatus is mounted on a lower side of the sensor unit; a deformation space is formed in a position on the lower side of the sensor unit opposite the force transmission apparatus; and the deformation space allows the sensor unit to deform along the direction of the stress; and
wherein the fixing apparatus includes a main body portion and an extension portion extending along the main body portion and wherein the main body portion is configured to include a recess to accommodate the sensor unit.
