The supporting plate 221 is mounted at the bottom of the containing cavity 211, the power generation gear 222 is rotationally connected with the supporting plate 221, the power generation gear 222 is engaged with the power generation rack 223, the top of the power generation rack 223 is connected with the bottom of the supporting plate 23, the power generation gear 222 is in transmission connection with an input shaft 2241 of the power generator, the power generator 224 is connected with the storage battery 225, the bottom of the elastic piece 227 is connected with the bottom of the containing cavity 211, the top of the elastic piece 227 is connected with the bottom of the supporting plate 23, and the supporting plate 23 is located above the power generation base 21. The weighing device 3 comprises a weighing sensor, a display supporting rod 31 and a display 32. The weighing sensor is mounted at the bottom of the power generation base 21, the display supporting rod 31 is mounted at the rear end of the power generation base 21, the display 32 is mounted on the display supporting rod 31 and is in communication connection with the weighing sensor, and the storage battery 225 is connected with the display 32.

[0048] The power generation gear 222 is connected with the supporting plate 221 through a rotating shaft, so that the power generation gear 222 is rotationally connected with the supporting plate 221. In actual use, a passenger places luggage on the supporting plate 23, the supporting plate 23 moves downward along a first direction X relative to the power generation base 21, the elastic piece 227 is compressed, meanwhile, the power generation rack 223 moves downward, the power generation gear 222 is driven to rotate through the engagement relationship with the power generation rack 223, the power generation gear 222 transmits power to the input shaft 2241 of the power generator through transmission, and power generation is realized. When the luggage is placed in place, the weighing sensor weighs and displays the weight data of the luggage through the display 32. When the passenger takes away the luggage after weighing, the supporting plate 23 is not affected by external force, the supporting plate 23 returns to the initial state under the action of the elastic piece 227, so as to be used by the next passenger. The elastic piece 227 has elasticity, can be elastically contracted when subjected to pressure, and can return to the initial shape when the pressure disappears. The elastic piece 227 can be made of metal elastic materials such as metal springs, or non-metal elastic materials such as rubber and silica gel.

[0049] Since the storage battery 225 has limited and unstable power storage capacity, in actual use, the display 32 is generally provided with power, and the power of the weighing sensor and other equipment can be connected through an external power source. Therefore, mechanical energy is converted into electrical energy, the dependence on external power is reduced, the energy utilization efficiency is improved, and the operation cost is reduced.

[0050] According to some embodiments of the present application, as shown in Figure 3 The power generation assembly 22 further comprises a first pulley 2261, a first belt 2262, a second pulley 2263, a second belt 2264 and a third pulley 2265. The first pulley 2261 is mounted on the support plate 221 and rotates coaxially with the power generation gear 222. The first pulley 2261 is in driving connection with the second pulley 2263 through the first belt 2262. The second pulley 2263 is mounted on the middle part of the support plate 221. The second pulley 2263 is in driving connection with the third pulley 2265 through the second belt 2264. The third pulley 2265 is mounted on the input shaft 2241 of the generator.

[0051] The first pulley 2261 rotates coaxially with the power generation gear 222 through a rotating shaft. The power generation gear 222 and the first pulley 2261 are located on the two sides of the support plate 221 respectively. The power generation gear 222 and the input shaft 2241 of the generator are in driving connection through the belt. In actual use, the passenger places the luggage on the support plate 23. The support plate 23 moves downward along the first direction X relative to the power generation base 21. The elastic member 227 is compressed. At the same time, the power generation rack 223 moves downward. The power generation rack 223 drives the power generation gear 222 to rotate through the meshing relationship. The power generation gear 222 drives the coaxial first pulley 2261 to rotate. The first pulley 2261 drives the second pulley 2263 to rotate synchronously through the first belt 2262. The second pulley 2263 drives the third pulley 2265 to rotate synchronously through the second belt 2264. Finally, the input shaft 2241 of the generator rotates to generate electricity. In some embodiments, power transmission can also be achieved through chain transmission or gear transmission.

[0052] In other embodiments, a limit stopper (the limit stopper can be a pawl) is arranged between the power generation gear 222 and the first pulley 2261. The first pulley 2261 can only rotate in the clockwise direction. When the power generation rack 223 is subsequently lifted, the first pulley 2261 is prevented from being reversed by the power generation rack. Thus, the function of protecting the generator 224 is achieved, which avoids the reverse rotation of the input shaft due to inertia or reverse torque caused by the sudden interruption of external power or the sudden change of load.

[0053] According to some embodiments of the present application, as shown in Figure 3 The diameter of the second pulley 2263 is greater than the diameter of the third pulley 2265.

[0054] By setting the diameter of the second pulley 2263 to be greater than the diameter of the third pulley 2265, the rotation speed of the third pulley 2265 is faster, the input shaft 2241 of the generator rotates faster, and the power generation efficiency is improved.

[0056] By setting the lifting device 4, the luggage can be lifted to the same height as the supporting plate 23, so that the passenger can avoid lifting the luggage and placing it, and the passenger can be facilitated to weigh. In actual use, the mounting rack 5 is in the lowest position, facilitating the passenger to place the luggage on the mounting rack 5, and when the luggage is placed, the lifting device 4 is started to lift the mounting rack 5 to the same level as the supporting plate 23, and the passenger can move the luggage to the supporting plate 23 to weigh.

Specifically, the connecting rod 42 is driven to rotate by the lifting motor 41, and the supporting block 45 and the mounting rack 5 are driven to lift by the rotating rod 43 and the transmission rod 44, so as to support the luggage.

[0061] According to some embodiments of the present application, optionally, as shown in Figure 1 and Figure 6As shown, the lifting device 4 further comprises two sets of guide assemblies 46, which are respectively installed at the front end and the rear end of the mounting frame 5.

[0062] In order to make the lifting of the lifting device 4 more stable, the guide assembly 46 is arranged. When the mounting frame 5 is lifted, the connecting plate 461 is lifted, so that the guide sliding sleeve 462 slides along the guide sliding rod 463, thereby playing a guiding and supporting role. Alternatively, a plurality of guide sliding sleeves 462 and a plurality of guide sliding rods 463 can be arranged, the connecting plate 461 is sleeved outside the plurality of guide sliding sleeves 462, and one guide sliding sleeve 462 corresponds to one guide sliding rod 463.

[0063] According to some embodiments of the present application, the optional Figures 7 to 10 As shown, the airport luggage weighing device 100 further comprises a pushing device 6, the pushing device 6 comprises two sets of moving assemblies 61 and a pushing assembly 62, the top of the mounting frame 5 is provided with an opening 51, and the top of the mounting frame 5 is further provided with two sliding grooves 52 extending to the opening 51 along the second direction Y; the two sets of moving assemblies 61 are respectively installed at the front end and the rear end in the mounting frame 5, the moving assembly 61 comprises a moving motor 611, a moving lead screw 612, a moving block 613 and a limiting rod 614, the output end of the moving motor 611 is connected with the moving lead screw 612, the moving lead screw 612 is installed on the mounting frame 5 along the second direction Y, the moving block 613 is sleeved outside the moving lead screw 612 and is in threaded connection with the moving lead screw 612, and the limiting rod 614 is installed on the mounting frame 5 after penetrating through the moving block 613 along the second direction Y; the pushing assembly 62 comprises two pushing motors 621 and an L-shaped pushing frame 622, the two pushing motors 621 are respectively installed on the opposite surfaces of the two moving blocks 613, and the two pushing motors 621 are connected with the L-shaped pushing frame 622; wherein the pushing motor 621 is used to drive the L-shaped pushing frame 622 to protrude out of the opening 51, and the moving motor 611 is used to drive the L-shaped pushing frame 622 to move along the second direction Y.

[0065] In the initial position, the opening 51 is arranged away from the support plate 23, and the L-shaped pushing frame 622 is located below the opening 51. When the luggage needs to be pushed, the pushing motor 621 drives the L-shaped pushing frame 622 to rotate to protrude into the opening 51, and the moving motor 611 drives the L-shaped pushing frame 622 to push the luggage to the left along the second direction Y along the two sliding grooves 52 to the support plate 23.
