[0034] Referring to Figures 1 to 7 , a suitcase with a weighing function proposed in an embodiment of the present utility model includes a box body 100, a handle assembly 200, a locking assembly, a weighing assembly 400, a pressing plate 500, and a power generation assembly 600.
[0035] A roller 110 is installed under the box body 100 to facilitate the movement of the box body 100. The box body 100 can be opened to store items inside. One end of the pull rod assembly 200 is installed on the box body 100, and the other end can be extended relative to the box body 100. When the suitcase is not in use, the pull rod assembly 200 is in a retracted state to reduce the occupied space. When the suitcase is in use, the other end of the pull rod assembly 200 is extended relative to the box body 100 to facilitate the user to operate the pull rod assembly 200. The locking assembly is installed on the pull rod assembly 200. The locking assembly includes a driving unit 310 and an action unit 320. The driving unit 310 is used to drive the action unit 320 to lock or unlock the telescopic movement of the pull rod assembly 200 relative to the box body 100. The locking assembly is used to lock the pull rod assembly 200 when the suitcase is not in use to prevent the pull rod assembly 200 from extending. The weighing assembly 400 is arranged on the pull rod assembly 200, including a weighing sensor 410, a control board 420 and an information output component 430, and the weighing sensor 410 and the information output component 430 are both connected to the control board 420; the pressing plate 500 is arranged on the side of the pull rod assembly 200 facing the box body 100, and the pressing plate 500 is used to connect with the weighing sensor 410; the pressing plate 500 only contacts the weighing sensor 410, and by holding up the pressing plate 500 by hand, the weight of the entire suitcase is applied to the weighing sensor 410 through the pressing plate 500, and the control board 420 receives the signal of the weighing sensor 410, and calculates the weight of the suitcase through the built-in program, which is very convenient. The power generation component 600 is arranged on the pull rod component 200, and is connected to the drive unit 310 by transmission. The power generation component 600 is electrically connected to the control board 420; a suitcase with a pull rod generally has a locking component, and the locking component usually has a drive unit 310. In this embodiment, the power generation component 600 is driven by the drive unit 310 of the suitcase itself to generate electricity, and there is no need to set up an independent drive unit 310, which makes full use of the existing structure of the suitcase and realizes the multi-purpose function of the drive unit 310.
[0036] In summary, the embodiment of the utility model utilizes the locking assembly of the suitcase itself for locking the pull rod assembly 200 to drive the power generation assembly 600 to generate electricity, and the power generation assembly 600 generates electricity to supply the control board 420, and the control board 420 controls the weighing sensor 410 to weigh, and outputs the weighing result to the outside through the information output component 430.
[0037] The specific process is as follows. When it is necessary to know the weight of the luggage, the user only needs to apply a force with the hand on the pressing plate 500, and lift the luggage off the ground by lifting the pressing plate 500. At this time, the weight of the entire luggage is applied to the weighing sensor 410 through the pressing plate 500. The control board 420 receives the signal from the weighing sensor 410 and calculates the weight of the luggage through the built-in program, which is very convenient. The technical solution of the present utility model does not require a specially set structure for the driving power generation component 600, and uses the existing structure of the luggage itself for driving, so that the weighing function of the luggage can be realized at a relatively low cost.
[0038] Among them, in some embodiments of the present utility model, a storage battery is provided on the control board 420, and the power generation component 600 can supply power to the storage battery and supply power to the weighing component 400 when weighing is required.
[0039] In some embodiments of the present utility model, a storage battery may not be provided on the control board 420, and the power generation component 600 supplies power to the weighing component 400 in real time.
[0040] As Figures 2 to 4 described, in some embodiments of the present utility model, the handle assembly 200 includes two telescopic rod groups 210 and a grip 220. The telescopic rod groups 210 are arranged vertically. One end of the telescopic rod groups 210 is connected to the box body 100, and the other end is used to be connected to the grip 220. The grip 220 is arranged horizontally. Both ends of the grip 220 are respectively connected to the two telescopic rod groups 210. The telescopic rod groups 210 are driven to expand and contract relative to the box body 100 through the grip 220. The driving unit 310 includes a button 330, a transmission cross bar 340 and a transmission vertical bar 350. The button 330 is in transmission connection with the transmission cross bar 340, and the transmission cross bar 340 is in transmission connection with the transmission vertical bar 350 through an inclined plane structure. The transmission vertical bar 350 is in transmission connection with the action unit 320. Part of the button 330 is exposed above the grip 220, and the button 330 can move up and down for convenient operation. When the button 330 moves downward, the transmission cross bar 340 can be driven to slide left and right through the inclined plane structure. The left and right sliding of the transmission cross bar 340 can push the transmission vertical bar 350 to descend, and the descent of the transmission vertical bar 350 can drive the action unit 320 to act. The above-mentioned handle assembly 200 adopts inclined plane transmission, with a relatively simple structure, convenient processing and stable operation.
[0041] Specifically, the telescopic rod group 210 can be a single tube. A blind hole for accommodating the telescopic rod group 210 is provided on the box body 100, and a positioning hole for cooperating with the action unit 320 is provided on the side wall of the blind hole. The action unit 320 is arranged inside the telescopic rod group 210. The action unit 320 has an elastic positioning member 360 that can protrude from the side wall of the telescopic rod group 210. By inserting the elastic positioning member 360 into the positioning hole, the movement of the telescopic rod group 210 relative to the box body 100 can be limited. When the transmission vertical rod 350 moves downward, it can control the elastic positioning member 360 to retract into the telescopic rod group 210. At this time, the telescopic rod group 210 can move relative to the box body 100.
[0042] Of course, the telescopic rod group 210 can also be two tubes nested together, including an inner tube and an outer tube. The inner tube is inserted into the outer tube, and the inner tube is fixed on the box body 100. A positioning hole for cooperating with the action unit 320 is provided on the side wall of the inner tube. The action unit 320 is arranged inside the outer tube. The action unit 320 has an elastic positioning member 360 that can protrude from the side wall of the outer tube. By inserting the elastic positioning member 360 into the positioning hole, the movement of the inner tube relative to the box body 100 can be limited. When the transmission vertical rod 350 moves downward, it can control the elastic positioning member 360 to retract into the inner tube. At this time, the inner tube can move relative to the box body 100.
[0043] As Figures 2 to 4 described, in some embodiments of the present invention, the power generation assembly 600 has a gear set 610 and a power generation unit. A rack 370 is provided on the transmission cross bar 340. The gear set 610 meshes with the rack 370. The rack 370 can be integrally formed directly on the transmission cross bar 340, or the rack 370 is first processed and then assembled onto the transmission cross bar 340. By driving the gear set 610 with the rack 370, the gear set 610 amplifies the rotational speed and then drives the power generation unit to generate electricity. The power generation unit can adopt a structure for generating electricity by cutting magnetic induction lines. This structure is relatively mature and will not be elaborated here.
[0044] Specifically, as Figures 2 to 3As described above, in some embodiments of the present utility model, the interior of the holding member 220 has a first installation cavity 230, and the holding member 220 is provided with an installation hole 240 communicating with the first installation cavity 230. The key 330 is vertically inserted and installed in the installation hole 240. First inclined surfaces 250 are provided on both the left and right sides of the lower end of the key 330. The first inclined surfaces 250 can be 45-degree chamfers or chamfers at other angles. The transmission cross bar 340 is slidably installed in the first installation cavity 230. A second inclined surface 260 is provided on the side of the transmission cross bar 340 close to the key 330. The second inclined surface 260 cooperates with the first inclined surface 250 so that the downward movement of the key 330 can drive the transmission cross bar 340 to slide outward horizontally. A first return spring 290 is provided between the transmission cross bar 340 and the holding member 220. When the key 330 no longer applies power, the transmission cross bar 340 can be brought back to the starting position by the first return spring 290 to prepare for the next drive. During the return process, the transmission cross bar 340 can also drive the power generation assembly 600 to generate electricity with high power generation efficiency.
[0045] Specifically, as Figures 5 to 7 described above, in some embodiments of the present utility model, a second installation cavity is provided in the telescopic rod group 210. The transmission vertical rod 350 is slidably installed in the second installation cavity. A third inclined surface 270 is provided at the upper end of the transmission vertical rod 350. A fourth inclined surface 280 that cooperates with the third inclined surface 270 is provided on the side of the transmission cross bar 340 close to the transmission vertical rod 350. The cooperation between the two enables the outward horizontal movement of the transmission cross bar 340 to drive the transmission vertical rod 350 to descend. A second return spring is provided between the transmission vertical rod 350 and the telescopic rod group 210. When the transmission cross bar 340 no longer exerts pressure on the transmission vertical rod 350, the transmission vertical rod 350 will rise back to the starting position under the action of the second return spring to prepare for the next action.
[0046] It should be noted that in some embodiments of the present utility model, when the above-mentioned inclined surface structure has a guiding structure, that is, after the inclined surface structure is assembled, the key 330 and the transmission cross bar 340 are not separated, and the two are synchronously linked during the return process. The transmission cross bar 340 and the transmission vertical rod 350 are not separated, and the two are synchronously linked during the return process. At this time, the first return spring 290 and the second return spring may not be provided, and the return of the key 330 is used to drive the return of the transmission cross bar 340 and the transmission vertical rod 350.
[0047] It should be noted that the power generation assembly 600 is not limited to being driven by the transmission cross bar 340. For example, in some embodiments of the present invention, the power generation assembly 600 has a gear set 610, a rack 370 is provided on the transmission vertical rod 350, and the gear set 610 meshes with the rack 370. By using the up and down movement of the transmission vertical rod 350, the power generation assembly 600 can also be driven to generate electricity. Similarly, it is also by using the driving unit 310 of the locking assembly inherent in the trunk itself, without the need to additionally set up a driving structure, so that the present invention can realize the weighing function of the trunk at a relatively low cost.
[0048] Specifically, as Figure 1 and Figure 2 described, in some embodiments of the present invention, the information output member 430 is set as a display screen, and the weight is displayed in digital form through the display screen for the user to view in time, which is very convenient.
[0049] In addition, it can be understood that the information output member 430 can also be set as a speaker, and the weighing result is directly played through the speaker. Generally, the display screen is relatively small, and for users with poor eyesight, there is occasionally a problem that it is not easy to view. The speaker enables the user to not need to watch the display screen with eyes and can just listen to the result with ears.
[0050] As Figure 2 described, in some embodiments of the present invention, there are two weighing sensors 410. The weighing sensors 410 are arranged in the holding member 220. Avoidance holes are provided on the side wall of the holding member 220 facing the box body 100 corresponding to the weighing sensors 410. The pressing plate 500 is provided with two connecting columns 510. The two connecting columns 510 pass through the avoidance holes and are respectively connected to the two weighing sensors 410. The connecting columns 510 and the weighing sensors 410 are connected by screws. The two weighing sensors 410 cooperate with the pressing plate 500, and basically can cover the range when the human hand operates the holding member 220. Compared with a single weighing sensor 410, the technical solution of this embodiment can act on the weighing sensor 410 the force on the pressing plate 500 in a relatively vertical direction, improving the accuracy and stability of weighing.
[0051] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combinations of these technical features do not conflict, they should all be considered as the scope described in this specification.
[0052] Certainly, the present invention is not limited to the above-described embodiments. Those skilled in the art can also make equivalent deformations or substitutions without departing from the spirit of the present invention, and these equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
