Description

Soft Weighing System

technical field

The invention relates to a weighing system, and in particular to a soft weighing system with foldable properties for easy storage.

Background technique

When people take an airplane, the airline will provide passengers with free luggage delivery benefits. For example, each person can carry 20 kilograms of luggage on the plane they take. However, most families do not have a tool to weigh the luggage. Weigh your luggage first. Or passengers bought some items to put in the suitcase before boarding the plane. They also need to determine whether the weight of the suitcase is overweight. If it can be kept below the free weight, the consignment fee will be saved. Therefore, if there is a cheap and Easy-to-use weighing tools can be used, which is very convenient for passengers who often fly.

Traditional weighing tools are mostly made of metal products, which are large in size, heavy in weight, and cannot be folded. For users, they are not easy to carry or store.

As shown in FIG. 1 , FIG. 2A and FIG. 2B , US Patent No. 7,282,653 discloses a luggage weighing device. The weighing device 10 uses a metal plate 11 as a base material and has a first end 13 and a second end 14 . The first end 13 is provided with a first hole 16 and the second end 14 is provided with a second hole 17 . A bump 18 is arranged beside the metal plate 11 , and the side of the bump 18 close to the metal plate 11 is a scale surface 20 , and a scale 19 is arranged on the scale surface 20 . In use, the metal plate 11 is passed through the space below the handle H of the hand luggage S. The right finger passes through the hole 16 on the right side of the metal plate 11 to hold the first end 13 of the metal plate 11; the left finger passes through the hole 17 on the left side of the metal plate 11 to hold the second end 14 of the metal plate 11. Lift the suitcase S, because the metal plate 11 has only a small amount of bending and deformation ability, and the weight of the suitcase S can be seen by comparing the deformation amount with the scale 19.

However, the above-mentioned weighing device has many disadvantages, including: large volume, heavy weight, two-handed operation, and the reading technology of the mechanical scale reading on the metal plate 11, there will be significant interpretation errors, and the user cannot accurately obtain Luggage weight.

There are also products on the market that directly integrate the weighing device into the luggage. For example, in the suitcase proposed in Chinese patent application No. 200810081151.9, the pressure sensor is arranged between the handle and the box body of the suitcase. When the user lifts the suitcase through the handle, the pressure sensor will Can sense the weight of the suitcase itself. However, this design relatively increases the manufacturing cost and manufacturing process complexity of the suitcase, and the maintenance is not easy.

The battery box 33 is used for placing the battery, and the battery provides the electric power of the flexible weighing system 300 .

In more detail, the flexible substrate 30 is, for example, formed by attaching the lower flexible substrate 30B and the upper flexible substrate 30T, and its material is, for example, leather material or other suitable materials. Certainly, the flexible base material 30 can also be made by integral molding. On the premise of being rollable, the present invention does not limit the fabrication and composition of the flexible substrate 30 .

The two ends of the flexible base material 30 respectively have a first joint part and a second joint part, which are, for example, a first fastener 34 and a second fastener 342 respectively, so that after the flexible base material 30 is crimped, Combine to fix both ends of the flexible substrate 30 . In this embodiment, the first fastener 34 and the second fastener 342 are, for example, a combination of male and female press buttons to fix and combine the bent upper flexible substrate 30T and the lower flexible substrate 30B in position. In other embodiments, the first fastener 34 and the second fastener 342 may also be a combination of a male and a female Velcro or other combination with the same function.

In addition, the flexible weighing system 300 can also have a display element 35 for displaying weight information. The display element 35 has a wire 36 electrically connected to the control circuit on the circuit board 31 , and the wire 36 is disposed between the upper flexible substrate 30T and the lower flexible substrate 30B. The display interface of the display element 35 is exposed outside the flexible substrate 30, so that the user can see the weight information. In this embodiment, the display element 35 is, for example, a liquid crystal display.

FIG. 5 further illustrates the situation where the soft weighing system 300 is used to measure the weight of the suitcase S. As shown in FIG. The figure shows the state that the soft weighing system 300 is wrapped in the handle H of the suitcase S.

FIG. 6 is a block diagram of the circuit system of the flexible weighing system 300 . The control circuit 38 is located on the circuit board 31 , and the pressure sensor 32 is also disposed on the circuit board 31 and electrically connected to the control circuit 38 . The display element 35 is electrically connected to the circuit board 31 for displaying weight information. The flexible weighing system 300 of this embodiment may further include a weight warning selection element 37 and warning elements 352 , 353 . The weight warning selection element 37 is electrically connected to the control circuit 38 to select the weight warning potential, and the warning elements 352 and 353 are electrically connected to the control circuit 38 to issue a warning when the load on the pressure sensor 32 exceeds the weight warning potential .

FIG. 7 shows a flexible weighing system 300 with a weight warning selection element 37 and warning elements 352 , 353 . The figure shows that a weight warning selection element 37 is set on the surface of the upper flexible substrate 30T to provide the user with a choice of the weight warning potential, for example: 20KG or 40KG is the warning threshold (threshold). The warning component can be: a sound warning component 352, such as a horn, etc.; it can also be a light warning component 353, such as a light emitting diode (light emitted diode, LED) and the like. When the weight of the suitcase S exceeds the set value, the sound warning element 352 or the light warning element 353 can be used to send a warning message. In more detail, when the light signal is used as a warning: after turning on the power switch (not shown in the figure), the green light (G) is always on, and when the weight W of the suitcase S exceeds the set value, the green light (G) goes out and the red light (R) lights up. When the sound is used as a warning: after the power switch is turned on, the sound is a continuous slow "beep beep" sound, and when the weight W of the suitcase S exceeds the set value, the sound is a continuous rapid "beep beep" sound.

In addition, some airlines set a limit of 20 kilograms, and additional charges must be made for more than 20 kilograms. Or some airlines set a limit of 40 kilograms, and additional fees must be charged when it exceeds 40 kilograms. The user can set or select the weight warning potential through the weight warning selection element 37 . When the weight limit is 20 kg, the weight warning potential can be set at 20 kg, then when the weight of the suitcase exceeds 20 kg, the soft weighing system 300 will send out a warning light or a warning sound. Through the weight warning selection element 37, the user can also set the weight warning potential at 40 kg, then when the weight of the suitcase exceeds 40 kg, the soft weighing system 300 will emit a warning light or a warning sound.

To sum up, the flexible weighing system of the present invention can accurately and quickly test the weight of the suitcase, and has the characteristics of being foldable, easy to carry and store. The flexible weighing system of the present invention can provide a portable wallet type weighing tool that can be folded and stored.
