Description
Technical Field
The utility model relates to a teaching technical field especially relates to a dolly teaching aid of motion.
Background
In current physical teaching, need demonstrate the student under many circumstances to in better combine together classroom theory knowledge and practice, inclined plane dolly experimental apparatus is just one, but present inclined plane dolly experimental apparatus is very crude in the reality generally to put up the inclined plane of random angle by the plank and demonstrate data and the expression of data can't reach accurate degree through traditional scale measuring distance, and the student inconveniently observes in teaching process.
In conclusion, the design provides a moving trolley teaching aid which overcomes the defects in the way of adjusting and measuring the distance by a steering engine, an ultrasonic sensor and a laser sensor respectively and in the way of displaying by a dot matrix screen.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a dolly teaching aid of motion.
In order to realize the purpose, the utility model discloses a realize through such technical scheme, a dolly teaching aid of motion, including linear guide, linear guide's right-hand member portion is equipped with ultrasonic sensor laser sensor, linear guide's left end is connected with the inclined plane through the steering wheel, slidable mounting has the dolly on the inclined plane, still be provided with the straight potentiometer that slides on the steering wheel, slidable mounting has the thing piece on the linear guide, linear guide's side still is equipped with first dot matrix screen and second dot matrix screen respectively.
Further, first dot matrix screen the second dot matrix screen the straight sliding potentiometer and ultrasonic sensor/laser sensor electric connection respectively is on automatically controlled board, automatically controlled board is fixed to be set up inside the linear guide, and wherein the straight sliding potentiometer input signal passes through main control board conversion signal feedback is in show the angle on the first dot matrix screen, ultrasonic sensor/laser sensor passes through main control board conversion signal feedback is in show the distance on the second dot matrix screen.
Furthermore, a battery box is embedded in the linear guide rail, and the first dot matrix screen, the second dot matrix screen, the straight sliding potentiometer, the ultrasonic sensor/laser sensor and the steering engine are powered through the battery box.
The beneficial effect of above-mentioned scheme is:
the utility model discloses an inclined plane is connected to the steering wheel and the angle that uses the straight smooth potentiometre to raise the inclined plane is adjusted, it makes can be accurate to decimal point back two to the measurement of distance still to carry out distance measurement through the ultrasonic sensor laser sensor who sets up at the linear guide tip in addition, and still observe through the distance that first dot matrix screen and second dot matrix screen audio-visual angle and the thing piece that rises to the inclined plane suffered to remove after the striking, moreover, this design still has convenient to use, the accurate measurement distance so that the advantage of the more audio-visual impression of student.

Fig. 1 is a schematic view of the main structure of the present invention.
In the figure: 1. a linear guide rail; 2. a bevel; 3. a trolley; 4. a steering engine; 5. blocking; 6. ultrasonic/laser sensors; 7. a first dot matrix screen; 8. a second dot matrix screen.
Detailed Description
The present invention will be further clearly and completely described with reference to the accompanying drawings, but the scope of the present invention is not limited thereto.
Example 1:
as shown in fig. 1, a dolly teaching aid of motion, including linear guide 1, linear guide 1's right-hand member portion is equipped with ultrasonic sensor/laser sensor 6, linear guide 1's left end is connected with inclined plane 2 through steering wheel 4, slidable mounting has dolly 3 on the inclined plane 2, steering wheel 4 is last still to be provided with and directly to slide the potentiometre and pass through directly slide potentiometre control steering wheel 4, slidable mounting has thing piece 5 on linear guide 1, linear guide 1's side still is equipped with first dot matrix screen 7 and second dot matrix screen 8 respectively.
In this embodiment, first dot matrix screen 7 second dot matrix screen 8 the straight potentiometer and ultrasonic sensor/laser sensor 6 electric connection respectively is on automatically controlled board, automatically controlled board is fixed to be set up linear guide 1 is inside, and wherein the straight potentiometer input signal that slides passes through main control board conversion signal feedback is in show the angle on the first dot matrix screen 7, ultrasonic sensor/laser sensor 6 passes through main control board conversion signal feedback is in show the distance on the second dot matrix screen 8.
In this embodiment, a battery box is further embedded inside the linear guide rail 1, and the battery box supplies power to the first dot matrix screen 7, the second dot matrix screen 8, the straight sliding potentiometer, the ultrasonic sensor/laser sensor 6 and the steering engine 4.
Specifically, the utility model discloses when using, dolly 3 is followed and is adjusted the inclined plane 2 of angle through straight smooth potentiometre control steering wheel and go up the appointed distance slip and fall, striking thing piece 5, make thing piece 5 sliding motion right on linear guide 1, thereby by the accurate displacement distance who acquires thing piece 5 of the position change of 6 perception thing pieces of ultrasonic sensor laser sensor 5 (generally accurate to decimal point back two), and at this in-process inclined plane 2's angle, and the distance that thing piece 5 changes demonstrates respectively on first dot matrix screen 7 and second dot matrix screen 8 and makes the student can this experiment of more audio-visual observation.
It is above-mentioned first dot matrix screen 7 the second dot matrix screen 8 the straight sliding potentiometer and the circuit that ultrasonic sensor/laser sensor 6 and automatically controlled board are connected should be regarded as prior art, and battery case is right in addition the utility model provides a supply circuit of each components and parts should also be regarded as prior art, the utility model discloses in do not give unnecessary details.
The embodiment of the present invention discloses a preferred embodiment, but not limited thereto, and those skilled in the art can easily understand the spirit of the present invention according to the above-mentioned embodiment, and make different applications and changes, but do not depart from the spirit of the present invention, all of which are within the protection scope of the present invention.
