The movable housing is rotationally connected to the main housing about the axis of the transmission shaft, and the movable housing and the transmission shaft rotate synchronously. The scale is convenient and reliable in operation, safe and reliable in use, and provides a high user experience. However, the self-generating operation requires both hands to operate, which is relatively difficult. Summary of the Invention

[0004] The purpose of this application is to provide a luggage scale with a self-generating structure in order to solve the problem that the luggage scale is difficult to operate with self-generating power.

[0005] The present application provides a luggage scale with a self-generating structure that adopts the following technical solutions:

[0006] A luggage scale with a self-generating structure comprises:

[0007] A mounting housing having a slide port and a weighing port;

[0008] The power generation structure includes a sliding push piece, a connecting portion, a gear, and a generator. The sliding push piece is provided at a sliding opening and can slide relative to the mounting housing so that an operator can push the sliding push piece through the sliding opening. The connecting portion is connected to the sliding push piece on the inner side of the mounting housing. The connecting portion has a serrated edge that engages with the gear so that the sliding push piece drives the gear to rotate, and the gear contacts the generator to drive the generator to generate electricity.

[0009] The weighing structure includes a weighing hook, which protrudes from the weighing port to connect with the object to be weighed.

[0010] By adopting the above technical solution, the mounting housing is used to house the generator's power generation structure, weighing structure, and other components. A sliding plate opening and a weighing opening are provided in the mounting housing, allowing the user to move the sliding plate through the sliding plate opening. The connecting portion transmits the sliding plate's horizontal movement to the gear in the form of rotation via the serrated edge, thereby driving the generator to generate electricity. The weighing opening provides a weighing hook that protrudes from the inside of the mounting housing and is used to weigh items. By using the sliding plate to perform power generation, the user can operate the luggage scale with one hand, making it more convenient to operate.

[0011] Optionally, the power generation structure further includes a reset spring, a connecting piece is provided on the inner side of the mounting shell, and the reset spring connects the connecting piece and the connecting portion.

[0012] By adopting the above technical solution, the return spring is used to return the sliding push piece to its original position through elastic force after the sliding push piece is moved by external force. Since the operation of moving the sliding push piece is more suitable for hand force than pushing it in two directions, the return spring allows the operator to move the sliding push piece only in one direction, which is beneficial to improving the operability of the luggage scale.

[0013] Optionally, the weighing structure further includes a sensor, which is disposed in the mounting housing and connected to the weighing hook.

[0014] By adopting the above technical solution, the sensor is used to sense the weight of the item hooked by the weighing hook. Through the sensor, the luggage scale can accurately measure the weight of the weighed item, thereby improving the accuracy of the luggage scale.

[0015] Optionally, the luggage scale further comprises a battery, which is connected to the generator and the sensor respectively.

[0016] By adopting the above technical solution, the battery is connected to the generator and the sensor respectively, which is used to store the electricity generated by the generator and provide power to the sensor when the sensor needs power, so that the power generated by the generator will not be wasted.

[0017] Optionally, the luggage scale further includes a control structure, which includes a display screen and control buttons, and the display screen and control buttons are arranged on the surface of the mounting shell.

[0018] By adopting the above technical solution, the display screen is used to obtain the weighing information and working status of the luggage scale. The control button can adjust the working mode of the luggage scale, allowing the operator to adjust the desired working mode according to needs.

[0019] Optionally, the number of gears is three, and the three gears are connected in sequence.

[0020] By adopting the above technical solution, the three gears can expand the pushing range of the sliding push piece, allowing the sliding push piece to rotate the generator over a large range within a smaller sliding range. In addition, the three gears can also transmit rotation, transferring power from the sliding push piece at the edge of the mounting housing to the generator in the middle of the mounting housing.

[0021] Optionally, the mounting shell includes a top cover and a bottom cover, the top cover has a first connecting tube, the bottom cover has a second connecting tube, and the first connecting tube and the second connecting tube are connected to fix the bottom cover and the top cover.

[0022] By adopting the above technical solution, the top cover and the bottom cover enable the installation shell to be opened, making it easier to install, repair and adjust the components inside the installation shell. Through the first connecting pipe and the second connecting pipe, the top cover and the bottom cover can be connected by bolts and other parts, making the connection and separation of the two more convenient and quick.

[0023] Optionally, both the top cover and the bottom cover have gear rods for mounting gears.

[0024] By adopting the above technical solution, the gear rod is used to install the gear. By arranging the gear rods on both the top cover and the bottom cover, the gear can be fixed from both sides, thereby making the power generation structure run stably.

[0025] Optionally, the sliding push piece is provided with a pushing portion, and a surface of the pushing portion has friction patterns.

[0026] By adopting the above technical solution, the pushing part can protrude from the sliding plate mouth, so that the operator can push the sliding push plate more conveniently, and the surface of the pushing part has friction patterns, which prevents the pushing part from slipping and can be pushed more conveniently.

[0027] Optionally, the sliding push piece is further provided with a sliding rod, the inner side wall of the mounting shell is provided with a sliding groove, and the sliding rod slides in the sliding groove.

[0028] By adopting the above technical solution, the sliding rod can support the sliding push piece in the installation shell while reducing the contact area between the sliding push piece and the installation shell, thereby reducing the sliding resistance; and the sliding groove can limit the sliding range of the sliding push piece and maintain the sliding stability of the sliding push piece.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. The mounting housing is used to mount the generator's power generation structure, weighing structure, and other components. Sliding vane openings and weighing openings are provided on the mounting housing, allowing the user to move the sliding vane through the sliding vane openings. The connecting portion transmits the sliding vane's horizontal movement to the gear in the form of rotation via the serrated edge, thereby enabling the gear to drive the generator to generate electricity.

[0031] 2. Since it is more suitable for the hand to exert force in one direction to move the sliding push piece than to push it in two directions, the reset spring allows the operator to only exert force in one direction to move the sliding push piece, which is conducive to improving the operability of the luggage scale;

[0032] 3. The pushing part can protrude from the sliding piece opening, so that the operator can push the sliding piece more conveniently, and the surface of the pushing part has friction patterns, which prevents the pushing part from slipping and can be pushed more conveniently; the sliding rod can support the sliding piece in the mounting shell while reducing the contact area between the sliding piece and the mounting shell, thereby reducing the sliding resistance; and the sliding groove can limit the sliding range of the sliding piece and maintain the sliding stability of the sliding piece.

[0039] The present application is further described in detail below with reference to the accompanying drawings.

[0040] A luggage scale with a self-generating structure, referring to Figure 1 and Figure 2The luggage case comprises a mounting housing 1, a power generation structure, a weighing structure 3, a battery 4, and a control structure 5. The mounting housing 1 serves as a mounting carrier for the luggage case, and the power generation structure, weighing structure 3, battery 4, and control structure 5 are all mounted on the inside or outside of the mounting housing 1. The mounting housing 1 comprises a top cover 14 and a bottom cover 15. The top cover 14 is provided with a first connecting tube 16, while the bottom cover 15 is provided with a second connecting tube 17. The two can be connected to each other, thereby fixing the bottom cover 15 and the top cover 14, ensuring the overall stability and durability of the device while enabling quick installation and disassembly. A sliding port 11 is provided between the top cover 14 and the bottom cover 15, while a weighing port 12 is provided on the bottom cover 15.

[0041] Reference Figure 3 and Figure 4 The power generation structure includes a sliding push piece 21, a connecting portion 22, a gear 23, a generator 24, and a return spring 25. The sliding push piece 21 is positioned at the slide opening 11 and is provided with a push portion 211 and a sliding rod 213. The push portion 211 protrudes from the slide opening 11, and the surface of the push portion 211 is provided with friction patterns 212. The friction patterns 212 increase the friction between the finger and the push portion 211, while the push portion 211 protrudes from the surface of the mounting housing, making it easier for the operator to push the sliding push piece 21. The sliding rod 213 is provided on both sides of the sliding push piece 21. The inner side wall of the mounting housing is provided with a sliding groove 19. The sliding rod 213 can slide within the sliding groove 19, thereby driving the sliding push piece 21 to slide relative to the mounting housing 1. Connecting portion 22 connects to sliding push piece 21 inside mounting housing 1. Connecting portion 22 has a serrated edge 221 that engages gear 23, allowing sliding push piece 21 to rotate gear 23. Gear 23 then contacts generator 24, driving generator 24 to generate electricity. The three gears 23 amplify the force of sliding push piece 21, driving generator 24 more efficiently, and enabling transmission of rotation over longer distances to ensure stable operation of the luggage scale.

[0042] Reference Figure 2 and Figure 5 Both the top cover 14 and the bottom cover 15 are equipped with a gear rod 18, which is used to mount the support gear 23, ensuring that the gear 23 can rotate while maintaining the stable position of the gear 23. A connecting member 13 is also provided on the inside of the mounting shell. The connecting member 13 is fixed relative to the mounting shell and is connected to a return spring 25. When the sliding push piece 21 is pushed, the return spring 25 is stretched. When the sliding push piece 21 is released, the return spring 25 can pull the sliding push piece 21 back to its initial position, allowing the operator to move the sliding push piece 21 back and forth by simply applying force in one direction. This is suitable for the force mode of the hand and improves the operability of the luggage scale.

[0043] Reference Figure 1 、 Figure 2 and Figure 4 The weighing structure 3 includes a weighing hook 31 and a sensor 32. The weighing hook 31 protrudes from the weighing port 12 and is used to connect the item to be weighed. The sensor 32 is arranged in the mounting shell 1 and is connected to the weighing hook 31. The sensor 32 is used to convert the weight signal on the weighing hook 31 into an electrical signal for subsequent processing and display. The battery 4 is connected to the generator 24 and the sensor 32 respectively. The electric energy generated by the generator 24 can be stored in the battery 4 to avoid waste of electricity. When there is surplus electricity, the luggage scale can be used without self-generation. The control structure 5 includes a display screen 51 and a control button 52, both of which are arranged on the surface of the mounting shell 1. The display screen 51 is used to display the weighing results, while the control button 52 allows the user to set the device, such as unit switching, clearing and other operations.

[0044] The operating principle of this embodiment is as follows: the user pushes the push portion 211 protruding from the push opening to push the sliding push piece 21. The sliding push piece 21 drives the connecting portion 22 to move. The serrated edge 221 on the edge of the connecting portion 22 drives the gear 23 to rotate. The rotation of the gear 23 further drives the generator 24 to generate electricity, thereby providing power for the luggage scale. When using the luggage scale, after pushing the sliding push piece 21, the user can hang the item to be weighed on the weighing hook 31 and view the specific weight of the item on the display.

[0045] The examples of this specific embodiment are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
