Abstract
The utility model discloses a device for displaying a two-part allegorical saying, and belongs to a teaching tool for the Chinese. The device comprises a substrate, a microcontroller, a motor drive circuit, a baffle plate, and an LED display screen disposed at the front of the substrate. The right side of the LED display screen is provided with a motor. One end of the baffle plate is connected with the rotating shaft of the motor. The top of the substrate is provided with a button. The device provided by the utility model can display various types of two-part allegorical sayings for students, and can cover the second part of each two-part allegorical saying, so as to enlighten the thinking of the students and improves the learning interestingness of the students.
Description
Technical field
The utility model relates to a kind of two-part allegorical saying exhibiting device, belongs to Chinese teaching aid.
Background technology
Two-part allegorical saying is a kind of special linguistic form that Chinese people create in practical experience of life, and it is made up of front and back two parts: first half plays " introduction ", as riddle; Latter half plays " backsight ", as answer to a riddle.
In primary Chinese teaching, teacher need to understand some conventional two-part allegorical sayings with student.Traditional teaching method is two-part allegorical saying is directly write on the blackboard or make PPT to student viewing, and this method can not improve student's learning interest.
Utility model content
The utility model, for the problem in background technology, proposes a kind of two-part allegorical saying exhibiting device.
The utility model, for overcoming the above problems, adopts following technical scheme:
A kind of two-part allegorical saying exhibiting device, comprises substrate, microcontroller, motor-drive circuit, baffle plate and is located at the LED display of substrate front side; The right side of described LED display is provided with a motor; One end of described baffle plate is connected with the turning axle of motor; The top of described substrate is also provided with a button; Described button is connected with the signal input part of microcontroller; Described microcontroller is by motor-drive circuit control machine operation; Described LED display is connected with microcontroller by serial port communication line.
Preferably, described motor adopts stepper motor.
Technique effect:
1, the utility model can be shown various two-part allegorical sayings to student, and the latter half of two-part allegorical saying can be covered, and to inspire student's thinking, improves student's learning interest.
2, the utility model is rational in infrastructure, simple to operate, is convenient to promote in each school.

Fig. 3 is the constitutional diagram of Electric Machine Control baffle plate while leaving LED display front.
Label title in Fig. 1, Fig. 2, Fig. 3: 1, substrate; 2, LED display; 3, motor; 4, baffle plate; 5, button.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is done in further detail and is introduced:
Structure of the present utility model as shown in Figure 1, comprises substrate 1, microcontroller, motor-drive circuit, baffle plate 4 and is located at the LED display 2 in substrate 1 front; The right side of described LED display 2 is provided with a motor 3; One end of described baffle plate 4 is connected with the turning axle of motor 3; The top of described substrate 1 is also provided with a button 5; Described button 5 is connected with the signal input part of microcontroller; Described microcontroller is worked by motor-drive circuit control motor 3: described LED display 2 is connected with microcontroller by serial port communication line, and microcontroller is worked by the mode control LED display 2 of serial communication.
Described motor 3 adopts small-sized stepper motor; Described microcontroller adopts the P89V51RD2FA of NXP company; Described motor-drive circuit is mainly made up of the L298N doube bridge driver of ST company, for stepper motor is controlled; Described button 5 adopts self-replaced type button; Described baffle plate 4 adopts rectangular plastic plate, and its length is about the half of LED display 2 length, and motor 3 can be controlled baffle plate 4 half, the right side of LED display 2 screen is covered.
Be a teacher and press the button at 5 o'clock, microcontroller can be received the signal that button 5 transmits, and control LED display 2 and demonstrate a two-part allegorical saying, the first half of this two-part allegorical saying is displayed on half, the left side screen of LED display 2, the latter half of this two-part allegorical saying is displayed on half, the right side screen of LED display 2, simultaneously, the front of LED display 2 right half screen controlled baffle plate 4 and gone to by microcontroller by motor 3, so that the latter half of two-part allegorical saying is covered to (as shown in Figure 2), now, student can only see the first half of two-part allegorical saying, teacher can allow student think deeply according to the first half expansion imagination of two-part allegorical saying.Be a teacher and again press the button at 5 o'clock, the front of LED display 2 controlled baffle plate 4 and left by microcontroller by motor 3, the latter half of two-part allegorical saying is showed to student's (as shown in Figure 3).
