Description
[technical field]
The utility model relates to a kind of digital dolly, is specifically related to the digital dolly of a kind of Measuring Time and displacement relation, belongs to tutor auxiliary platform apparatus technical field.
[background technology]
In the teaching process of physics class, to time of object and displacement relation demonstrate usually adopt dotted timer, paper tape matching track dolly realizes, but the function singleness of this experimental apparatus, application condition is large, operation requirements is high, easily causes the failure of an experiment.
Therefore, for solving the problems of the technologies described above, the necessary digital dolly providing a kind of novel Measuring Time and displacement relation, to overcome described defect of the prior art.
[utility model content]
For solving the problem, the purpose of this utility model is to provide a kind of structure simple, easy to use, diverse in function and the digital dolly of the high Measuring Time of accuracy and displacement relation.
For achieving the above object, the technical scheme that the utility model is taked is: the digital dolly of a kind of Measuring Time and displacement relation, and it comprises housing, wheel, axletree, track, code-disc, photoelectricity door, data processing module, wireless transmitter module and battery; Wherein, described axletree is articulated on housing; Described wheel is installed on axletree, and it can along rail moving; Described code-disc is installed on wherein on an axletree, it is evenly placed with a circle light hole; Described photoelectricity door is contained in housing, and it clamps described code-disc; Described data processing module and photoelectricity door, wireless transmitter module are electrically connected; Described battery connects and is that photoelectricity door, data processing module and wireless transmitter module are powered.
The digital dolly of Measuring Time of the present utility model and displacement relation is set to further: described track is aluminum alloy rail, and its end face both sides are provided with rail groove; Described wheel is embedded in this rail groove.
The digital dolly of Measuring Time of the present utility model and displacement relation is also set to: the radius of described wheel is 25mm.
Compared with prior art, the utility model has following beneficial effect: it is simple that the digital dolly of Measuring Time of the present utility model and displacement relation has structure, easy to use, the plurality of advantages such as diverse in function and accuracy are high, it can the parameter such as Measuring Time, displacement, speed in real time, and is sent by wireless transmitter module.
[accompanying drawing explanation]
Fig. 1 is the structural representation of the digital dolly of Measuring Time of the present utility model and displacement relation.
Fig. 2 is the stereographic map of Fig. 1 middle orbit.
Fig. 3 is the enlarged drawing at A place in Fig. 1.
[embodiment]
Refer to shown in Figure of description 1 to accompanying drawing 3, the utility model is the digital dolly of a kind of Measuring Time and displacement relation, and it is made up of a few parts such as housing 1, wheel 2, axletree 3, track 4, code-disc 5, photoelectricity door 6, data processing module 7, wireless transmitter module 8 and batteries 9.
Wherein, described axletree 3 is articulated on housing 1.Described wheel 2 is installed on axletree 3, and it can move along track 4.The radius of described wheel 2 is 25mm.
Described track 4 is aluminum alloy rail, and its end face both sides are provided with rail groove 41; Described wheel 2 is embedded in this rail groove 41, thus ensures that dolly is at track 4 moving linearly, and not easily drops from track 4.
Described code-disc 5 is installed on wherein on an axletree 3, and rotates with axletree 3.Described code-disc 5 is evenly placed with a circle light hole 51, the angle namely between adjacent two light holes 51 is identical.
Described photoelectricity door 6 is contained in housing 1, and it clamps described code-disc 5.
Described data processing module 7 and photoelectricity door 6, wireless transmitter module 8 are electrically connected, its signal that can produce according to photoelectricity door 6, calculate displacement and the time of moving of car, and related data are sent by wireless transmitter module 8.
Described battery 9 connect and be photoelectricity door 6, data processing module 7 and wireless transmitter module 8 power.
The principle of work of the digital dolly of Measuring Time of the present utility model and displacement relation is as follows: when dolly moves on track 4, wheel 2 drives axletree 3 to rotate, axletree 3 code-disc 5 that links rotates, light hole 51 on code-disc 5 makes photoelectricity door 6 produce break-make change, and according to the time of photoelectricity door 6 by two adjacent light holes 51, the angular velocity of code-disc 5 can be calculated, the namely angular velocity of wheel 2, because the radius of wheel 2 is certain, the displacement of dolly, speed and the relation of time so just can be calculated.
Above embodiment is only the preferred embodiment of this creation, and not in order to limit this creation, any amendment made within all spirit in this creation and principle, equivalent replacement, improvement etc., within the protection domain that all should be included in this creation.
