Embodiment 1

[0026] The present invention provides such Figure 1-5 Shown in order to achieve the above object, the present invention provides the following technical solutions:

[0027] A letter spelling machine, comprising a main body shell 1, a loudspeaker 2 is fixedly installed on one side of the front end of the main body shell 1, and a start switch 3 is arranged on a side far from the loudspeaker 2 at the front end of the main body shell 1, the main body shell The front end of 1 is located below the loudspeaker 2, and a keyboard 4 is fixedly installed. The outer surface of the front end of the main body shell 1 is located in front of the keyboard 4 and is hinged with a gray plate 5. The inner side of the main body shell 1 is movably installed with a storage box 6. , the inside of the main body shell 1 is equipped with a display screen 7, the front end of the display screen 7 is fixedly installed with a camera 8 on the upper end, and two sets of slide rails 9 are arranged on both side...

Embodiment 2

[0037] A protection method for a letter-spelling machine, including the letter-spelling machine, and also includes the following methods:

[0038] Push the display screen 7 out along the slide rail 9, during the process of pushing, the spring 10 will be stretched continuously, and the baffle 12 will be pushed away by the connection button 11 and then quickly closed;

[0039] When the display screen 7 is fully pushed out, the baffle plate 12 will block the connection button 11, preventing the spring 10 from pulling the connection button 11 back;

[0040] One end of the baffle plate 12 is connected by a torsion spring, and the torsion force of the torsion spring is slightly greater than the tension of the spring 10 when the display screen 7 is pushed out;

[0041] When the device falls, the main body casing 1 is vibrated, and under the action of external force, the spring 10 will drive the connecting button 11 to open the baffle 12, retract the connecting button 11, and drive th...

Abstract

The present invention discloses a letter spelling machine and a protection method. The letter spelling machine comprises a main body casing. A speaker is fixedly installed to one side of the front endof the main body casing, and one side of the front end of the main body casing away from the speaker is provided with a start switch. According to the invention, slide rails, springs, connecting buttons, baffle plates and a protective plate are used, when people uses the letter spelling machine, the letter spelling machine can be pushed out along the sliding rails, when the letter spelling machine is completed pushed out, the baffle plates block the connecting buttons, the springs are prevented from pulling the connection buttons back, one end of each of the baffle plates is connected by a torsion spring, and the torsion force of the torsion spring is slightly larger than the pulling force of the spring when a display screen is pushed out. When equipment falls, the main body casing is vibrated, under the action of external force, the springs drive the connecting buttons to open the baffle plates, the connecting buttons are retracted, the display screen connected to one side of each ofthe connecting buttons, the display screen is retracted into the main body casing, the secondary damage to the display screen is avoided, and therefore, the safety of the equipment is improved.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to an alphabet spelling machine and a protection method. Background technique [0002] With the continuous progress of the times, people pay more and more attention to children's education. People usually buy some electronic products to instill some basic knowledge to children while children are playing for them. The existing letter spelling machine lacks certain When children are using the device, it is easy to drop the device from a high place, causing certain damage to the device, and damage to the device can easily cause children to be injured, so the significance of protecting the device is not only the device itself , also for the protection of children in use. [0003] Therefore, it is necessary to invent a kind of letter spelling machine and protection method to solve the above problems. Contents of the invention [0004] The purpose of the present invention is to pro...
