To better understand the structure and positional relationship of the present invention, before beginning the description of the embodiments of the present invention, the structure of the infant incubator will be briefly described. Infant incubators typically include a relatively enclosed space for an infant to live in, referred to as an infant compartment, which is fixedly mounted on a movable general support frame. The bottom of the baby cabin is provided with a bed body tray 2, the lower part of the bed body tray 2 is provided with a bed body base 1, the lower part of the bed body base 1 is provided with a bed body frame 4 with a supporting function, and the bottom of the bed body frame 4 is provided with a bottom cover plate 3 with a covering function.

The following describes in detail embodiments of the present invention with reference to the accompanying drawings.

Referring to fig. 1 to 5, an infant incubator weighing system includes four load cell assemblies 5. Each load cell assembly 5 comprises a sensor unit 52 and a weighing tip 51, the weighing tip 51 being adapted to contact an object such as a pallet carrying a baby. The weighing tip 51 is detachably connected to the sensor unit 52 by means of studs 53, the studs 53 transmitting the pressure carried by the weighing tip 51 to the sensor unit 52. The four sensor units 52 are distributed at the bottom of the bed base 1 in a rectangular shape and are fixedly installed with the bed base 1. The bed body base 1 is provided with abdicating holes 11 which are in one-to-one correspondence with the sensor units 52, the lower ends of the studs 53 are connected with the sensor units 52, and the upper ends of the studs 53 penetrate through the abdicating holes 11 and are connected with the weighing tips 51. The utility model discloses a baby's incubator weighing system mounting structure is simple, and the dismouting is maintained conveniently, can be alone certain sensor module of dismouting or sensor unit inspect and maintain.

Preferably, the stud 53 includes a cylindrical middle section and a threaded connection section respectively connected to both ends of the middle section, and the middle section is provided with a longitudinal section for positioning. The lower end of the stud 53 is in threaded connection with the sensor unit 52, and the upper end of the stud 53 is in threaded connection with the weighing tip 51. The weighing tip 51 includes a disc-shaped connecting portion having a screw hole therein. The top of the connecting part is provided with a supporting part with a spherical structure. In this embodiment, the stud 53, the sensor unit 52 and the weighing tip 51 are detachably connected by threads, so that the stud is convenient to disassemble and assemble, labor-saving and convenient to maintain.

Referring to fig. 3 to 5, four corners of the bottom of the bed base 1 are respectively provided with a mounting seat for mounting the sensor unit 52. The sensor unit 52 includes a load cell 521 and a sensor mounting bracket 522, the load cell 521 is fixedly mounted on the sensor mounting bracket 522 by screws, and the sensor mounting bracket 522 is fixedly mounted on the mounting base by screws. In the installation process, the weighing sensor 521 and the sensor mounting bracket 522 can be assembled firstly, and then the sensor mounting bracket 522 and the mounting seat are installed, so that the installation difficulty is reduced, and the damage to the sensor 521 which may be symmetrically transmitted in the assembly process is reduced.

Preferably, the mounting seat comprises two L-shaped enclosing plates 12, and one end of each of the two L-shaped enclosing plates 12 is connected in parallel, so that the two L-shaped enclosing plates 12 enclose a frame which is viewed from top or from bottom as a U-shape. The abdicating hole 11 arranged on the bed base 1 is located at the inner side of the U-shaped frame, so that the load cell 521 is just surrounded by the surrounding plate 12 from three sides after the assembly of the sensor unit 52 with the bed base 1 is completed. It can be seen that the arrangement of the coaming 12 can better protect the weighing sensor 521, and the weighing sensor 521 is prevented from being damaged by external collision and the like after being installed.

Preferably, the mounting holes 13 are formed at the ends of the L-shaped enclosing plates 12 and/or at the connection of the two L-shaped enclosing plates 12. The mounting hole 13 extends longitudinally through the shroud 12. The outer wall of the mounting hole 13 is connected to or integrally formed with the shroud 12. The sensor mounting bracket 522 is provided with a screw hole matched with the position and size of the mounting hole 13, and when the sensor unit 52 is mounted, the screw hole of the sensor mounting bracket 522 is aligned with the mounting hole 13 and then a screw is screwed in. In this embodiment, the number of the mounting holes 13 is three, and the mounting holes are respectively distributed at the ends of the two enclosing plates 12 and the connecting position of the two enclosing plates 12. In other embodiments, there may be other numbers, and the distribution positions may be adjusted accordingly. For example, four mounting holes 13 are distributed at four corners of a rectangular frame surrounded by the enclosure 12. The mounting hole 13 is arranged on the coaming 12, so that the thread depth is increased, and the mounting is firmer; and also facilitates the mating of the mount with the sensor mounting bracket 522.

As shown in fig. 6 and 7, a bed frame 4 is arranged at the bottom of the bed base 1, and a bottom cover plate 3 is arranged at the bottom of the bed frame 4. Because four sensor units 52 are arranged at four corners of the bottom of the bed body base 1, weighing signals collected by the four sensor units 52 need to be transmitted to the circuit board 44 by cables, and the circuit board 44 is electrically connected with a control system of the infant incubator. The circuit board 44 is fixedly mounted on the bed frame 4.

In this embodiment, the bed frame 4 has a plurality of support beams 44 connected in a criss-cross manner, the support beams 44 are all hollow structures, and the hollow structures of the cross support beams 44 are communicated with each other. The hollow structure of the support beam 44 forms a wiring channel 43 inside, and a cable connected to the sensor unit 52 is routed through the wiring channel 43. Therefore, the bed body frame 4 can effectively prevent the cables from being damaged by coming and external scraping and the like.

In order to reduce the electromagnetic interference on the lines, the bed frame 4 is made of a metal material, such as stainless steel, copper plating, carbon steel, copper, aluminum, and the like. Of course, other materials with low resistance and high permeability are possible. And the conductive paint can be uniformly sprayed on the bed body frame 4 to form a shielding layer. In the prior art, no effective measure for shielding the cable from electromagnetic interference is taken, so that the electromagnetic interference brings errors to the weighing result. In many cases, the weight of the infant does not change much, and such weighing errors are likely to cause erroneous judgment of the treatment condition of the infant. The effective shielding of the electromagnetic interference of sensor unit 52 connecting cable can be realized to the structure of the bed body frame 4 of this embodiment, improves and weighs the degree of accuracy, diagnoses for the baby and provides more reliable data support.

Preferably, the side wall of the support beam 44 of the bed frame 4 is provided with a plurality of threading holes 41, and the threading holes 41 are communicated with the routing channels 43. Threading hole 41 is circular hole or waist type hole, and the distribution and the quantity of threading hole 41 are designed according to actual line and threading needs. The threading holes 41 are provided to facilitate the exit or entry of cables into the routing channels 43.

Preferably, the edge of the threading hole 41 is provided with a protective coil 42, and the protective coil 42 is a rubber ring for covering the fast opening at the edge of the threading hole 41. The protective coil 42 can protect the cable and prevent the cable from being cut by the quick opening at the edge of the threading hole 41.

Although the present disclosure has been described above, the scope of the present disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and such changes and modifications will fall within the scope of the present invention.
