TWM588990U - A weighable school backpack - Google Patents

Abstract

This creative department is a school bag with weighing function, including two parts: weighing device and control display device. The schoolbags of primary school students in China are generally overweight. Long-term carrying of overweight schoolbags will lead to poor growth and posture. The invention can measure the weight of the contents in the schoolbag and send it back to the school and parents. In addition, the teacher can transfer homework and contact items to the control and display device of the school bag through a mobile device or computer; the schoolchild can directly view homework and contact items through the display device on the school bag. In addition, the school children can also draw personalized patterns on the display device directly on the schoolbag; and watch the growth of the pets issued by the teacher.

Description

A schoolbag that can be weighed

This creative department is a schoolbag with weighing function. The weighing device is placed on the bottom of the school bag. When the books are placed in the book package, the weighing device can display the load-bearing data to the screen of the school bag, and can send the data to the computer or mobile device at both ends of the teacher and parents through wireless communication. In addition, the display device on the schoolbag can also receive homework data from the class and communicate with the teacher; this screen also allows the schoolchildren to draw patterns and display medal electronic pets.

The TWM407659U announced by the Taiwan Intellectual Property Bureau on July 21, 2011, whose name is the patent of "a weight warning school bag", includes: a body, which is a school bag, and has an accommodating space inside, and Two straps are provided on one back side of the body to assist the user to carry; a weight sensor corresponding to a bottom wall in the accommodating space of the body, which can sense the weight pressed on it , And output a driving signal when the weight exceeds a preset value; and a warning device, which is corresponding to the body, the warning device is electrically connected to the weight sensor, and can receive the driving signal Issue a warning.

This patent can weigh its weight, and when the weight exceeds the preset value, it can only issue a warning sound; it cannot transmit the actual weight value like this creation; and this creation has multiple functions and can give users different experiences.

This book was created as a schoolbag that can be weighed. Through the weighing device placed in the schoolbag, the weighed weight data is returned to the control display device, and then wirelessly transmitted to the mobile devices and computers of the school and parents. A display screen is inlaid on the schoolbag. This display screen allows students to draw and displays the homework and class assignments given by the teacher.

The first picture shows the appearance of the schoolbag created, which is composed of the schoolbag body 100 and the control and display device 110.

The second picture is the appearance of the weighing device created. The items in the schoolbag are placed directly on the scale bearing plate 200. The weight of these items is directly applied to the right weighing sensor 240 and the left weighing sensor 250. The two left and right weighing sensors are connected to the weighing device controller 260, and the weight data is then transmitted by the weighing device signal line 230 to the weighing signal connection 330 for controlling the display device 300. The two left and right weighing sensors are arranged in two protective plates of the weighing device protection upper plate 210 and the weighing device protection bottom plate 220.

The third figure is the authored control display device 300, which includes a display screen 310 for displaying information and graphics. A set of selection buttons 320 are used for function setting. Weighing signal The connection 330 is connected to the signal line 230 of the weighing device. The power required to control the display device 300 is connected to the equipment by the power connection 340.

The fourth picture is the main board 400 of the structure of the control display device created by the author. The main board is placed in the control display device 300; the main board has a touch color screen 410 for displaying graphics and touch operations. The button trigger jack 420 is connected to the selection button 320. The wireless communication module 430 transmits messages between the control processor 450 and the computer or mobile device. The control processor 450 is responsible for the control and coordination of all messages. The embedded controller 440 coordinates all the components on the main board 400 for controlling the display device structure and allows these components to communicate with each other.
