[0038] Reference Figures 1 to 10 One embodiment of the utility model provides a luggage scale, including a handheld device 100, a hanging device 200, a power generation device and an energy storage module. The handheld device 100 has a grip portion 110, a first connecting portion 120 and a first locking portion 130, and the handheld portion 110 is located between the first connecting portion 120 and the first locking portion 130. The hanging device 200 has a hanging portion 210, a second connecting portion 220 and a second locking portion 230, and the hanging portion 210 is located between the second connecting portion 220 and the second locking portion 230. The hanging portion 210 is provided with a weighing device 240, and the second connecting portion 220 is movably connected to the first connecting portion 120. The hanging device 200 and the handheld device 100 can move relative to each other and make the first locking portion 130 and the second locking portion 230 locked or separated with each other. The power generation device is provided on the handheld device 100, and the power generation device can generate electricity under the drive of an external force. The energy storage module is disposed on the handheld component 100 or the hanging component 200 , and the energy storage module is electrically connected to the power generation device and the weighing device 240 .

[0039] In the above structure, the luggage scale is divided into a handheld component 100 and a hanging component 200, and the first connecting portion 120 of the handheld component 100 is movably connected to the second connecting portion 220 of the hanging component 200. When in use, the hanging component 200 can be first moved relative to the handheld component 100 so that the second locking portion 230 moves away from the first locking portion 130. At this time, the hanging component 200 and the handheld component 100 are in an unlocked state, and the object to be weighed can be conveniently moved from the second locking portion 230 of the hanging component 200 to the second locking portion 230 of the hanging component 200. Hang it to the hanging part 210, and then move the hanging part 200 relative to the handheld item 100 so that the second locking part 230 moves close to the first locking part 130, and the second locking part 230 and the first locking part 130 are connected and locked with each other. At this time, the handheld item 100 and the hanging part 200 form a closed annular whole. At this time, the object to be weighed can be lifted by the hand grip 110 of the handheld item 100 for weighing, and it is not easy to shake, thereby making the weighing operation simpler and more convenient. Secondly, because the second locking part 230 is locked with the first locking part 130, the handheld item 100 and the hanging part 200 form a closed annular whole, and at this time, it can also prevent the hanging part 200 from scratching or interfering with other items, making it more convenient to carry and store the luggage scale.

[0040] In addition, by setting up a power generation device, the user can directly apply force to the power generation device, so that the power generation device converts mechanical energy into electrical energy and stores the electrical energy in the energy storage module, thereby supplying power to the weighing device 240 during weighing. This structure enables the luggage scale to have a self-generating function, without the need to repeatedly replace or charge the battery, making it convenient for users to use it anytime and anywhere.

[0041] It is understandable that the above-mentioned power generation device is provided on the portable device 100, which is only for Figures 1 to 10 An exemplary description is given. In addition, the power generation device can also be arranged on the weighing part, and the present utility model does not make any specific limitation on this.

[0042] Reference Figure 5 and Figure 6 In some embodiments, the power generation device includes a power generation coil 300 and a magnetic block 310 . The power generation coil 300 is electrically connected to the energy storage module, and the magnetic block 310 and the power generation coil 300 can move relative to each other.

[0043] In the above structure, when the magnetic block 310 and the generator coil 300 move relative to each other, the generator coil 300 can cut the magnetic flux lines to generate electric energy, and can store the electric energy in the energy storage module, thereby supplying power to the weighing device 240 during weighing. By adopting the above structure, the user can make the magnetic block 310 and the generator coil 300 move relative to each other by manually cranking the luggage scale or by vibrating the luggage scale during movement, thereby making the luggage scale have a self-generating function, and there is no need to repeatedly replace or charge the battery during use, which is convenient for users to use anytime and anywhere.

[0044] It is understandable that, referring to Figure 5 and Figure 6 , the magnetic block 310 and the power generation coil 300 can move relative to each other, specifically, the power generation coil 300 can be fixedly installed on the handheld 100, and the magnetic block 310 can be movably installed on the handheld and can move relative to the power generation coil 300, so that the power generation coil 300 can cut the magnetic flux lines to generate electric energy. Alternatively, the magnetic block 310 can be fixedly installed on the handheld 100, and the power generation coil 300 can be movably installed on the handheld 100 and can move relative to the magnetic block 310, thereby enabling the power generation coil 300 to cut the magnetic flux lines to generate electric energy. In addition, one of the power generation coil 300 and the magnetic block 310 can be fixedly installed on the hanging part 200, and the other can be movably installed on the hanging part 200. Alternatively, both can be movably installed on the handheld 100 or the hanging part 200, and the utility model does not make specific restrictions on this, as long as the magnetic block 310 and the power generation coil 300 can move relative to each other.

[0045] Reference Figure 5 and Figure 6 In some embodiments, the power generation device further includes a coil bracket 320 , the power generation coil 300 is wound around the outer circumference of the coil bracket 320 , a sliding cavity 321 is provided in the coil bracket 320 , and the magnetic block 310 is movably installed in the sliding cavity 321 and can move along the sliding cavity 321 .

[0046] In the above structure, by setting the coil support 320, the power generation coil 300 is wound around the outer periphery of the coil support 320, and the magnetic block 310 is movably installed in the sliding cavity 321 of the coil support 320, so that the magnetic block 310 can move relative to the power generation coil 300 along the sliding cavity 321 under the action of external force, and then the power generation coil 300 can cut the magnetic flux lines to generate electrical energy. By adopting the above structure, the user can manually crank the luggage scale or the luggage scale generates vibration during movement to make the magnetic block 310 move relative to the power generation coil 300 along the sliding cavity 321, thereby making the luggage scale have a self-generating function, and there is no need to repeatedly replace or charge the battery during use, which is convenient for users to use anytime and anywhere.

[0047] Reference Figure 5 and Figure 6 In some embodiments, two stop portions are provided on the periphery of the coil bracket 320, and the generating coil 300 is wound around the periphery of the coil bracket 320 and is located between the two stop portions, thereby fixing and limiting the generating coil 300 to avoid displacement or misalignment of the generating coil 300 when the luggage scale is shaken or vibrated.

[0048] It is understandable that in some embodiments, a handle connected to the magnetic block 310 and extending outward to the outside of the luggage scale can also be provided, so that the user can pull the handle to drive the magnetic block 310 to move along the sliding cavity 321 relative to the generating coil 300, thereby enabling the generating coil 300 to cut the magnetic lines of force to generate electrical energy.

[0049] Reference Figures 7 to 10 In some embodiments, the power generation device includes a drive assembly and a generator assembly 400, the generator assembly 400 includes a generator 410 and a gear set 420, the generator 410 is electrically connected to the energy storage module, one end of the gear set 420 is transmission-connected to the generator 410, and the other end is transmission-connected to the drive assembly, and the drive assembly can drive the generator 410 to generate electricity through the gear set 420.

[0050] In the above structure, the driving component can drive the gear set 420 to operate, and further drive the generator 410 to operate to generate electrical energy and store the electrical energy in the energy storage module, thereby supplying power to the weighing device 240 during weighing.

[0051] It can be understood that the gear set 420 includes a driving gear and at least one driven gear, and the driving gear is connected to the driving component, so that the user can drive the driving gear of the gear set 420 to rotate through the driving component, and the driving gear can drive the driven gear to rotate and finally drive the generator 410 to operate and generate electricity, thereby enabling the luggage scale to have a self-generating function. There is no need to repeatedly replace the battery or charge the battery during use, which is convenient for users to use it anytime and anywhere.

[0052] Reference Figures 7 to 10 In some embodiments, the handheld device 100 is provided with a first installation cavity 140 , and the power generation device is installed in the first installation cavity 140 .

[0053] In the above structure, by setting the power generation device in the first installation cavity 140 of the portable device 100, not only the installation space on the portable device 100 can be fully utilized, but also the user can operate it conveniently, and the user can drive the generator 410 to generate electricity through the driving component.

[0054] Reference Figure 7 and Figure 8In some embodiments, the driving assembly includes a rack 430 movably installed in the first installation cavity 140, the rack 430 is transmission-connected to the gear set 420, and the rack 430 is provided with a pressing portion 431 extending to the outside of the handheld device 100, and the pressing portion 431 can drive the rack 430 to move relative to the gear set 420 and make the gear set 420 operate.

[0055] In the above structure, the pressing part 431 can drive the rack 430 to move relative to the gear set 420 and drive the gear set 420 to operate, and then drive the generator 410 to operate to generate electricity and store the electricity in the energy storage module, so that the weighing device 240 can be powered during weighing. Specifically, by adopting the above structure, the user can press the pressing part of the rack 430 to drive the rack 430 to move relative to the gear set 420, and the rack 430 can drive the active gear of the gear set 420 to rotate, and the active gear can drive the driven gear to rotate and finally drive the generator 410 to operate to generate electricity, so that the luggage scale has the function of self-generating electricity, and there is no need to repeatedly replace the battery or charge the battery during use, which is convenient for users to use anytime and anywhere.

[0056] Reference Figure 7 and Figure 8 In some embodiments, the driving assembly further includes an elastic member 440 , one end of the elastic member 440 abuts against the bottom wall of the first mounting cavity 140 , and the other end abuts against the rack 430 .

[0057] In the above structure, by providing an elastic member 440, when the rack 430 is pressed to drive the rack 430 to move relative to the gear set 420, the elastic member 440 can drive the rack 430 to move and reset, and in the process can also drive the gear set 420 to operate in the opposite direction again, and then can drive the generator 410 to operate and generate electricity again, thereby facilitating the user to perform power generation operations, without repeatedly pressing the rack 430 and pulling out the rack 430. It is only necessary to press the pressing portion 431 of the rack 430, and the elastic force of the elastic member 440 can drive the rack 430 to move and reset. The structure is simple, the operation is convenient, and it can save effort for the user.

[0058] It is understandable that, referring to Figure 7 and Figure 8 A positioning column is provided in the first installation cavity 140, and the elastic member 440 is sleeved on the outer periphery of the positioning column, thereby positioning the elastic member 440 to prevent the elastic member 440 from being skewed or displaced when elastically contracted.

[0059] It is understandable that, referring to Figure 7 and Figure 8The number of the elastic members 440 is two, so that the rack 430 can be supported more stably. Of course, the number of the elastic members 440 may be one, three, four or more than two, and the present invention does not make any specific limitation on this.

[0060] It is understandable that the elastic member 440 can specifically be a compression spring. Of course, in addition to this, the elastic member 440 can also be made of other elastic materials such as a rubber pad, a silicone pad, etc., which is not specifically limited in the present invention.

[0061] Reference Figure 7 and Figure 8 In some embodiments, the second connection portion 220 is rotatably connected to the first connection portion 120 via a rotating shaft 250 .

[0062] In the above structure, the setting of the rotating shaft 250 enables the handheld item 100 to be rotatably connected with the hanging item 200, and the hanging item 200 can rotate relative to the handheld item 100 and drive the second locking portion 230 to move closer to or away from the first locking portion 130, thereby realizing the locking or separation between the second locking portion 230 and the first locking portion 130.

[0063] It is understandable that, in addition to being rotatably connected to the first connecting portion 120, in some embodiments, the second connecting portion 220 and the first connecting portion 120 can also be slidably connected. In this case, the hanging member 200 can slide relative to the handheld member 100 and move the second locking portion 230 closer to or away from the first locking portion 130. The present invention does not specifically limit the specific movable connection method between the first connecting portion 120 and the second connecting portion 220.

[0064] Reference Fig. 9 and Fig.10 In some embodiments, the rotating shaft 250 is installed on the second connecting portion 220 and extends to be rotatably connected to the first connecting portion 120. The driving assembly includes a worm 450 rotatably installed in the first mounting cavity 140. The worm 450 is transmission-connected to the gear set 420. One end of the worm 450 is connected to the rotating shaft 250, and the worm 450 is coaxially arranged with the rotating shaft 250. The rotating shaft 250 can drive the worm 450 to rotate.

[0065] In the above structure, the rotating shaft 250 can drive the worm 450 to rotate and drive the gear set 420 to operate, and then drive the generator 410 to operate to generate electrical energy and store the electrical energy in the energy storage module, so that the weighing device 240 can be powered during weighing. Specifically, by adopting the above structure, the user can directly rotate the hanging member 200 to rotate the rotating shaft 250 relative to the handheld member 100, so that the rotating shaft 250 drives the worm 450 to rotate and drives the driving gear of the gear set 420 to rotate, and the driving gear can drive the driven gear to rotate and finally drive the generator 410 to operate to generate electricity, so that the luggage scale has a self-generating function, which is simple and convenient to operate, and there is no need to repeatedly replace or charge the battery during use, which is convenient for users to use anytime and anywhere.

[0066] It can be understood that one end of the worm 450 is connected to the shaft 250, and the shaft 250 can drive the worm 450 to rotate. Fig. 9 and Fig.10 , a plug-in portion 253 is provided at one end of the rotating shaft 250 close to the worm 450, and a slot matching the plug-in portion 253 is provided at one end of the worm 450 close to the rotating shaft 250. In order to drive the worm 450 to rotate together when the rotating shaft 250 rotates, the plug-in portion 253 can be interference-fitted with the inner wall of the slot; or the cross-sectional shape of the plug-in portion 253 can be set to a non-circular shape such as a square or an ellipse, and the shape of the slot can be set to match the cross-sectional shape of the plug-in portion 253; in addition, the number of the plug-in portions 253 can be set to multiple, and a slot corresponding to the plug-in portion 253 is provided at one end of the worm 450 close to the rotating shaft 250. It should be noted that, in addition to the above structure to enable the worm 450 to rotate synchronously with the rotating shaft 250, the worm 450 and the rotating shaft 250 can also be connected by a clamping structure or other connection structure, which is not specifically limited by the present utility model.

[0067] It can be understood that, in addition to including the rack 430 or the worm 450, the driving component connected to the gear set 420 in transmission may also include a knob in some embodiments. The knob is connected to the driving gear of the gear set 420 and can drive the driving gear to rotate, so that the driving gear can drive the driven gear to rotate and finally drive the generator 410 to operate and generate electricity. In this way, the luggage scale has the function of self-generating electricity, which is simple and convenient to operate. There is no need to repeatedly replace the battery or charge the battery during use, which is convenient for users to use it anytime and anywhere.

[0068] Reference Figure 3 and Figure 4In some embodiments, the first connection part 120 is provided with a rotation groove 121 and a limit groove 122. The limit groove 122 is located on one side of the rotation groove 121 and is connected to the rotation groove 121. The rotating shaft 250 is connected to the second connection part 220 and is movably inserted in the rotation groove 121. A limit part 252 that can be movably embedded in the limit groove 122 is provided on one side of the rotating shaft 250. When the second connection part 220 rotates relative to the first connection part 120, the limit part 252 can move along the limit groove 122. When the limit part 252 moves to abut against the inner wall of one end of the limit groove 122, the hanging part 200 and the handheld part 100 cannot continue to rotate relative to each other, thereby limiting the rotation angle between the hanging part 200 and the handheld part 100.

[0069] Reference Figures 5 to 10 In some embodiments, the suspension member 200 is provided with a second installation cavity 260 for installing the weighing device 240 , and the rotating shaft 250 is provided with a wire passage 251 , which connects the first installation cavity 140 and the second installation cavity 260 .

[0070] In the above structure, the provision of the wire passage 251 can facilitate the passing of the wire, thereby facilitating the electrical connection between the generator 410 and the energy storage module or between the energy storage module and the weighing device 240 .

[0071] It is understandable that, referring to Figures 5 to 10 In some embodiments, the weighing device 240 includes a load-bearing member 241 and a weighing sensor 242. The weighing sensor 242 is disposed inside the hanging portion 210. The load-bearing member 241 is disposed on the surface of the hanging portion 210 and is located above the weighing sensor 242. The load-bearing member 241 can abut against the weighing sensor 242. Therefore, when the object to be weighed is hung on the hanging portion 210, the object to be weighed is hung on the upper surface of the load-bearing member 241, so that under the action of gravity, the load-bearing member 241 abuts against the weighing sensor 242 and applies pressure to the weighing sensor 242, thereby achieving weighing, which is simple to operate and has sensitive measurement.
