[0052] A lower surrounding wall 513 with a closed inner side and an open outer side is provided on the inner lower surface of the lower connecting plate 51, which surrounds the loading through hole.

[0053] 4. Weighing sensor 7

[0054] As shown in Figure 2 , Figure 6 , Figure 7 , Figure 8 , Figure 9 The weighing sensor 7 has a rectangular frame 71 made of steel material. A cantilever plate 72 extending into the rectangular frame 71 is provided on the outer frame of the rectangular frame 71. The cantilever plate 72 has a force receiving hole 74 at the inner end and a screw hole 75 at each corner of the rectangular frame 71. One half-bridge strain gauge sensor 73 of the weighing sensor 7 is attached to the lower surface of the cantilever plate 72 (the other half-bridge strain gauge sensor 73 of the weighing sensor 7 is installed on the bottom frame provided in another scale frame 2).

[0055] The fixed end of the strain gauge sensor 73 (preferably a resistance strain gauge) of the weighing sensor 7 is placed on the outer side of the cantilever plate 72, and the gravity loading end of the strain gauge sensor 73 is placed on the inner side of the cantilever plate 72. The inner end of the cantilever plate 72 is embedded in the lower surrounding wall 513, which restricts the displacement of the cantilever plate 72 in the horizontal plane, forward, backward and inward.

[0056] The rectangular frame 71 is fixed on the bottom frame of the scale frame 2 by screws passing through the screw holes 75 on the four corners of the rectangular frame 71, and the inner end of the cantilevered plate 72 is fixed on the bottom frame plate 5 by screws passing through the stress holes 74 and the loading through holes and being screwed into the loading screw holes 75 in sequence, so that the gravity loading end and the stress column 46 are fixed together.

[0057] The two half-bridge strain gauge sensor 73 is connected to the control circuit board 63 in a Wheatstone bridge mode through wires.

[0058] In the above structure, the contact between the gravity loading end and the stress column 46 can be made smaller, and the smaller contact can reduce the weighing error caused by the deviation of the force direction when the user lifts the luggage, so that the smaller contact can greatly improve the weighing accuracy.

[0059] II. Luggage handle 1

[0060] As shown in Figure 1 , Figure 2 , Figure 9 , it comprises a handle 12 held by the user when carrying the luggage, a stress hanging piece connected with the scale frame 2 arranged at both ends of the handle 12, and a weighing assembly, which is the weighing assembly described above.

[0061] The handle 12 can be made of plastic material, and the soft plastic material is preferred in the utility model, the stress hanging piece is the hanging ring piece 13, which is in an integral structure with the handle 12, the upper end of the hanging ring piece 13 is arranged on the inner side of the handle 12, and the hanging ring piece 13 is designed to be inclined from top to bottom and from inside to outside, and the outer end of the hanging ring piece 13 extends out of the handle 12, so that the length of the handle 12 can be shorter, and the stress hanging piece 13 is hidden and stored in the space between the top frame plate 4 and the bottom frame plate 5 in the scale frame 2 when the luggage is not lifted, and at this time, the distance between the handle 12 and the top surface of the luggage is also shorter, so that the handle 12 can be made smaller and in a nearly straight shape.

[0062] The hanging ring piece 13 is provided with a long strip through hole 14 extending from inside to outside, and the long strip through hole 14 is sleeved on the stress column 46 of the weighing assembly.

[0063] III. Stress explanation when lifting the luggage upward

[0064] 1. Since the stress column 46 is fixed with the gravity loading end, when the luggage is lifted upward, the hanging ring piece 13 pulls the stress column 46 upward to move the gravity loading end upward, at this time, the strain gauge sensor 73 deforms to output a weighing signal.

[0065] 2. Since the top frame plate 4 and the bottom frame plate 5 form a stable and reliable closed-loop structure, when the bag is lifted upward, the hanging ring 13 pulls the force-bearing column 46 upward and causes the gravity loading end to be subjected to an upward external force. When the force-bearing column 46 is pulled obliquely upward, it causes the outer end of the lower connecting plate 51 to press against the outer end of the suspended plate 72, that is, against the fixed end of the strain gauge sensor 73. In this way, the strain gauge sensor 73 deforms and outputs an electrical signal with a change in resistance.
