Description

A trolley case with weighing function

technical field

The utility model relates to the technical field of bags, in particular to a trolley case with a weighing function.

Background technique

At present, in business trips, each airline has a prescribed baggage weight check-in standard. However, because the traditional ordinary trolley case does not have a weighing function, some travelers may often encounter situations where they need to pay overweight fees due to overweight luggage.

For this reason, a Chinese utility model patent for "an improved electronic weighing type luggage handle" discloses a luggage handle structure that can weigh items in the suitcase (authorized announcement number is CN202386025U, Announcement date is August 22, 2012). The luggage handle includes a handle body, a tension sensor installed in the handle body, a chip board, a display screen connected to the chip board, an operation button and a weighing indicator light, wherein the operation button includes a function for controlling the power supply. On-off power button and unit selection button for weight unit conversion. When working, turn on the power button and lift the handle of the bag upwards. After the tension sensor feels the weight of the items in the bag, the tension sensor converts the physical signal into an electrical signal, and the electrical signal is transmitted to the chip board for data processing. The processed structure The weight of the items in the luggage can be displayed through the display screen, and the conversion between weight units can also be performed according to the choice of consumers. Yet because its whole casing of most luggage still adopts soft material to make now, especially luggage hand part. When the user lifts the bag and weighs it, the surface of the bag will be arched and bent, which makes the load-bearing structure of the bag with the above structure not stable and accurate, especially when the weight of the items in the bag is relatively heavy, the weighing instability is more obvious .

Contents of the invention

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a trolley case with a weighing function which has a simple structure, low cost and stable weighing effect.

In order to achieve the above purpose, the technical solution provided by the utility model is: a trolley case with a weighing function, including a trolley case body, a handle connected to the trolley case body, a tension sensor and a control device installed at both ends of the handle The chip and the display screen and power switch arranged on the end face of the handle, the handle is connected with the trolley case body through a rigid connecting plate arranged at both ends of the bottom, wherein the fixed end of the tension sensor is fixed in the handle cavity, and its tension The sensing end is in contact with the rigid connecting plate, and is used for sensing the weight of the object in the trolley case when the handle is lifted.

Further, the handle is also equipped with an alarm device for indicating that the weight of the box is overloaded, wherein the alarm device is connected with the control chip.

Preferably, the alarm device is a buzzer sound alarm.

Further, the handle is also provided with a weight unit conversion button, wherein the weight unit conversion button is connected to the control chip, and after the control chip receives the signal from the weight unit conversion button, the control chip controls the output of the display screen.

Further, a charging interface for charging the battery is also provided in the handle.

Compared with the prior art, the handle on the trolley case in the utility model is connected to the trolley case body through the rigid connecting plates connected at both ends, and the fixed end of the tension sensor is fixed in the handle cavity, and the tension sensing end in contact with the rigid connection plate. When the trolley case of this structure is lifted and used, it can effectively alleviate the problem of inaccurate weighing structure caused by the bending deformation of the trolley case; in addition, the trolley case is also equipped with an overweight alarm device in the inner cavity of the handle. When the weight of the items in the box exceeds the weight of the items when the box is designed, the alarm device can pick up the overweight items in the box for the user to avoid damage to the trolley box.

Detailed ways

Below in conjunction with specific embodiment the utility model is further described:

Referring to accompanying drawings 1 to 3, a trolley case with a weighing function described in this embodiment. The trolley case includes a trolley case body 8, a handle 1 connected to the trolley case body 8, a tension sensor 7 and a control chip 6 disposed in both ends of the handle 1, and a display screen 2 and a power switch 3 disposed on the end surface of the handle 1 . The handle 1 is connected with the trolley case body 8 through a rigid connecting plate 5 arranged at both ends of the bottom thereof. The fixed end 701 of the tension sensor 7 is fixed in the handle cavity, and its tension sensing end 702 is in contact with the rigid connecting plate 5 for sensing the weight of objects in the trolley case body 8 when the handle 1 is lifted. When the handle 1 is lifted, the tension sensing end 702 of the tension sensor 7 is deformed by the gravity of the items in the trolley case body 8, and the tension sensor 7 converts the physical deformation generated by it into an electrical signal and transmits it to the control chip 6 in the handle cavity On the top, the control chip 6 controls the display screen 2 located on the end face of the handle 1 to display and output according to the received electrical signal.

During the actual use of the trolley case, in some occasions (for example, the road condition is poor or the user is worried that the trolley case will be dirty due to too much water on the road, etc.), the trolley case needs to be lifted by the user for walking. In these processes, most users do not know the tensile force that the box they use can bear. If the weight of the items in the trolley box is too heavy, the handle of the trolley box will be damaged after long-term use. Therefore, this program is also equipped with an alarm device (not shown in the figure) for prompting that the items in the box are overweight on the handle 1 . Preferably, the alarm device adopts a buzzer sound alarm, which can quickly and better carry the user's trolley case with overweight items.

In addition, for users who frequently go to and from international airports, the weight of suitcases that are restricted to passengers in each country's airports is different and the weighing units used are different. In order to make it easier for customers to know in advance whether the luggage in their trolley case is overweight before taking the plane, this solution is also provided with a weight unit conversion button 4 on the handle 1, wherein the weight unit conversion button 4 is connected to the control chip 6, and the control chip 6 After receiving the signal from the weight unit conversion button 4, the control chip 6 controls the display screen 2 to output the corresponding weight unit conversion result.

In addition, in this solution, a charging interface is added to facilitate the user to charge the power supply battery in the handle cavity, which can better facilitate the user to travel.

When the trolley case is in use, it is necessary to turn on the power switch 3 on the end face of the handle 1, and then set it by operating the weight unit conversion button 4 to display the weight unit required by the user; then the handle 1 can be lifted to weigh the items in the trolley case. The user can check the weighing result through the display screen 2 on the end face of the handle 1; after the weighing is completed, turn off the power switch 3.

The implementation examples described above are only preferred embodiments of the present utility model, and are not intended to limit the scope of implementation of the present utility model, so all changes made according to the shape and principle of the present utility model should be covered by the scope of the present utility model. within the scope of protection.
