Specifically, detachable connection is adopted between the supporting structure 201 and the deformation unit 302, so that the replaceability of the supporting structure 201 and the sensor is improved. Further, a first through hole is formed in the supporting structure 201, the first through hole passes through the boss 202, a first threaded hole is formed in the stress point 303, and a fastener passes through the first through hole and is in threaded connection with the first threaded hole.
In some examples, the sensor is connected to the bed only by the fixing unit 301, the deformation unit 302 is not connected to the bed, i.e. the top of the deformation unit 302 is suspended, initially providing space for movement of the deformation unit 302.
The sensor is connected with the supporting structure 201 only through the deformation unit 302, the fixing unit 301 is not connected with the supporting structure 201, namely, the bottom of the fixing unit 301 is suspended, when the sensor is deformed, the distance between the supporting structure 201 and the sensor is reduced, and the space between the fixing unit 301 and the supporting structure 201 is convenient for relative movement between the supporting structure 201 and the sensor, namely, space is further provided for movement of the deformation unit 302.

The foot 100 in the second embodiment is configured to be disposed at a foot position, where the foot position is at a greater height from the floor surface and the mounting structure 401 is at a greater height. Specifically, the mounting structure 401 is approximately formed into a column shape, and the end face, connected with the bed body, of the mounting structure 401 can be embedded into the bottom of the position of the bed tail, so that a large enough contact area is ensured, and the connection stability is comprehensively improved by matching with the locking effect of the fastener.
In some examples, the mounting structure 401 employs a detachable connection with the fixed unit 301 to promote replaceability. Wherein, the mounting structure 401 is provided with a plurality of second threaded holes, the fixing unit 301 is provided with a plurality of second through holes, and each fastener respectively passes through each second through hole and forms threaded connection with each second threaded hole.
