Description

Carrier with weighing function

The present invention relates to a carrier having a weight measurement function, and more specifically, to a carrier for transporting luggage when traveling, which has a function of measuring the weight of the luggage stored inside the carrier, so that the luggage stored in the carrier can be measured. This relates to a carrier equipped with a weight measurement function that can easily check whether the weight of baggage exceeds the weight limit for each airline.

According to the International Air Transport Association, it is recommended that air baggage weigh less than 32 kg (70 lb), and some airlines stipulate that free checked baggage weighs 23 kg (50 lb).

The reason for limiting the weight of such baggage is, firstly, for the health and safety of workers transporting the baggage, and secondly, the heavier the weight loaded on the aircraft, the more fuel required.

When boarding an aircraft for a trip or business trip, luggage is stored and transported in a carrier such as (Patent Document 01). When measuring the weight of the carrier before boarding the aircraft at the airport, if the weight exceeds the airline's limit, the luggage is removed from the carrier and organized. There may be situations where you have to do it again. Therefore, the present invention is intended to apply the function of measuring the weight of the luggage stored in the carrier using a load cell to the carrier, so that the user can visually check the weight of the carrier and the luggage stored in the carrier .

The load cell above is a sensor that can measure physical quantities such as force or load. When force is applied to the load cell, an electrical signal is generated equal to the force. If the electrical signal is reinterpreted using an indicator, microcontroller, or computer device, the weight can be displayed in units such as kg or g.

A strain gauge is provided on the surface of the load cell, and the resistance value of the strain gauge changes as its shape changes. In other words, as the shape changes, it affects the electrical signal sent out by the load cell, and the weight can be measured through this numerical change.

Such load cells are used in devices for measuring weight, such as electronic scales, scales, and industrial scales, such as (Patent Document 02).

The present invention was created to more actively solve the above-mentioned problems, and the main problem is to provide a carrier with a weight measurement function that allows the weight of the carrier and the luggage stored in the carrier to be immediately measured and easily confirmed. .

In order to achieve the above-mentioned problem, the configuration of the carrier with a weight measurement function proposed in the present invention is as follows.
