Abstract
Description
Technical Field
[0001] This utility model relates to the field of self-generating luggage scales, and in particular to a self-generating luggage scale. Background Technology
[0002] Existing self-generating luggage scales, as portable weighing devices, are widely used in travel, logistics, and other scenarios. They convert mechanical energy into electrical energy through a built-in power generation module to power the weighing module, thus avoiding reliance on external batteries. Currently, common self-generating luggage scales typically employ a push-button power generation structure, where the user presses an exposed pressing part to drive gears in the power generation module, completing the energy conversion and powering the device.
[0003] However, this push-to-power generation structure has obvious technical defects:
[0004] The press-button section is exposed and cannot be retracted: In existing designs, the press-button section usually extends directly to the outside of the housing for easy user operation. However, when not in use, the press-button section cannot be retracted into the housing and remains exposed for extended periods. This not only occupies extra space but also makes the structure susceptible to structural damage or accidental triggering due to external impacts or pressure.
[0005] Poor portability: Because the pressing part protrudes from the outer shell, when carrying or storing the luggage scale (such as putting it in a suitcase or backpack), the exposed pressing part may interfere with other items, increasing the difficulty of storage and even affecting the placement of other items. Utility Model Content

[0033] See Figures 1-6 A self-generating luggage scale includes a housing 10, on which a power generation module 50 is disposed. A pressing part 20 is connected to the housing 10, and the pressing part 20 is movable or rotatable relative to the housing 10. The pressing part 20 is kinetically connected to the power generation module 50. The pressing part 20 can move or rotate relative to the housing 10 between a first position and a second position. An elastic element 70 is connected to the housing 10 and the pressing part 20, and the elastic element 70 applies force to the pressing part 20, holding it in the second position. The housing 10 is provided with a locking assembly 60, which locks the pressing part 20, holding it in the first position, thus keeping it in a retracted state. When the locking assembly is not locked, the user can freely press the pressing part, causing it to reciprocate between the first and second positions, thereby driving the power generation module to generate electricity. When storage is needed, the user presses the pressing part to move it to the first position. At the same time, the locking component locks the pressing part. In the locked state, the pressing part cannot move, that is, it cannot move to the second position, thus maintaining the storage state.
[0034] See Figure 4 The pressing part 20 is provided with a rack 540, and the power generation module 50 meshes with the rack 540 for transmission.
[0035] Furthermore, the pressing part 20 moves linearly between the first position and the second position relative to the outer shell 10, and the rack 540 is a straight rack.
[0036] Furthermore, the pressing part 20 is hinged to the outer casing 10, and the rack 540 is an arc-shaped rack, which is set with the rotation axis of the pressing part 20 relative to the outer casing 10 as the center. When the pressing part 20 rotates relative to the outer casing 10, the arc-shaped rack moves to drive the power generation module 50 to operate.
[0037] See Figure 4 The power generation module 50 includes a generator 510 disposed on the housing 10. The generator 510 has a first transmission gear 520 mounted on its motor shaft. The first transmission gear 520 meshes with a second transmission gear 530, which is rotatably mounted on the housing 10. The second transmission gear 530 meshes with a rack 540 for transmission. As the rack 540 moves, the rack 530 drives the second transmission gear 530 to rotate, which in turn drives the first transmission gear 520 to operate the generator 510 to generate electricity.
[0038] The locking assembly 60 includes a bolt 610 threadedly connected to the housing 10. The bolt 610 abuts against the rack 540, the first transmission gear 520, or the second transmission gear 530 to constrain the pressing part 20 relative to the housing 10 and keep the pressing part 20 in a first position.
[0039] See Figure 4 The bolt 610 abuts against the first transmission gear 520 to constrain the pressing part 20 relative to the outer casing 10, thereby keeping the pressing part 20 in the first position. The bolt 610 abuts against the first transmission gear 520 to achieve a limiting action.
[0040] Furthermore, a knob 630 is provided at the outward-facing end of the bolt 610. The function of the knob 630 is to facilitate the rotation of the bolt 610.
[0041] Furthermore, the bolt 610 has teeth 620 at one end facing the first transmission gear 520 that mesh with the first transmission gear 520. The teeth 620 are designed to facilitate insertion into the tooth grooves of the first transmission gear 520 for contact and restraint, thereby constraining the rotation of the first transmission gear.
[0042] See Figure 4 The front side wall of the outer casing 10 is provided with an opening 120, and the pressing part 20 is movably disposed in the opening 120; when the pressing part 20 is in the first position, the pressing part 20 is housed in the opening 120.
[0043] See Figure 4 The pressing part 20 is movably disposed relative to the outer casing 10. The pressing part 20 is provided with a guide member 200, and the guide member 200 is provided with a guide groove 210. The outer casing 10 is provided with a guide post 100, and the guide post 100 is movably inserted into the guide groove 210. The cooperation between the guide groove 210 and the guide post 100 not only constrains the pressing part 20 to move stably in a straight line relative to the outer casing 10, but also constrains the travel distance of the pressing part 20, preventing the pressing part 20 from separating from the outer casing 10.
[0044] See Figure 3 The outer casing 10 is provided with a circuit board 80 and a weighing module 30, a battery 90 and a display module 40 connected to the circuit board 80; the circuit board 80 is electrically connected to the power generation module 50.
[0045] The power generation module 50 is driven by the pressing part 20 to generate electricity, realize energy conversion and store electrical energy in the battery 90.
[0046] Furthermore, the weighing module 30 includes a weighing sensor 310 and a connecting hook 320. When the connecting hook 320 hangs an object, it connects to the sensing end of the weighing sensor 310 to weigh the object. The weighing sensor 310 is connected to the circuit board 80, and the circuit board 80 displays the weight information through the display module 40.
[0047] Furthermore, display module 40 is a display screen.
[0048] See Figure 6 The outer shell 10 is formed by assembling two half-shells 100 together.
[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
