Recessed heavy place, hanging structure are made of longitudinal hanging part and cross spacing part, and pass through longitudinal hanging part and cross spacing part and steel
Silk spring support 101, which coordinates, limits the upper and lower movement all around of holding members 103, so as to solve due to vehicle vibration and top
It winnows with a dustpan, finding out under ability when can generate human pressure's sensing station moving, offset and the human sensing detection thereby resulted in
The problem of drop.To sum up, due to the mounting means using mounting sunk type, with the prior art, the people's pressure sensor is not take up
The space on 101 top of steel wire spring support, it is oversized to avoid the plate carrying platform scale of construction, and caused space limitation is difficult to arrange people
The problem of pressure sensor.
In an of the invention specific embodiment, longitudinal hanging part and cross spacing part for stamped bending hook formation,
Groove-like structure or span shape bridging arrangement.The longitudinal hanging part of a pair of metallic plate both sides overlaps clip at 101 center of steel wire spring support
On the skeleton tension spring in longitudinal in-line of two of line both sides with bending feature, and the skeleton tension spring of longitudinal in-line at clip
In in parallel arrangement state.
Holding members 103 slide back and forth along the skeleton tension spring of two longitudinal in-lines with bending feature in order to prevent
Situation in the traversing section of skeleton tension spring, sets at least one cross spacing part to constrain the longitudinal sliding motion of holding members 103
Amount.
Longitudinal hanging part can connect and fix coupler body by left and right each longitudinal direction and form, can also be respectively by two and two
A above longitudinal direction connects and fixes coupler body composition.
In a specific embodiment of the invention, damping gasket layer is provided between longitudinal hanging part and steel wire spring support 101, it can
To prevent between human pressure's sensor and steel wire spring support 101, abnormal sound, abnormal sound are generated since gap is slided.
