Abstract
The utility model discloses a teacher's desk capable of being automatically lifted according to the stature. The teacher's desk comprises a base, wherein a supporting part is arranged on the base and is matched with a lifting column, and a desk top is arranged at the upper end of the lifting column. The teacher's desk is characterized in that a lifting device is arranged between the supporting part and the lifting column, a step motor gear is matched with the lifting column with a gear, and a step motor is connected with an image height identification sensor and an ultrasonic sensor. By adopting the technical scheme, according to the teacher's desk, the height of the teacher's desk can be automatically regulated; and for a speaker, the height of the teacher's desk can be automatically regulated according to the need of the stature, so that the fatigue caused by improper height when the speaker makes a speech can be reduced, and the speech effect can be improved.
Description
Technical field
Utility model relates to a kind of speech apparatus, specifically relates to a kind of lectern.
Background technology
Lectern is one of important lecture apparatus, and along with the development of society, lectern occurs in some important occasions more and more, as in important international conference, forum etc.But; Employed lectern height can not be regulated in important events at present, or promptly enables to regulate and also need manual adjustment, wastes time and energy; It is difficult to satisfy immediately different height lecturers' needs; Often, make VIP's effect when lecture not good enough, cause the decline of lecturer's public image because height and lectern do not match.
Summary of the invention
The utility model problem to be solved provides a kind of lectern that can regulate height immediately automatically.
For addressing the above problem, the technical scheme that the utility model adopted is: a kind of lectern comprises base; Base is provided with the support portion; Cooperate between support portion and the lifting column, the upper end of lifting column is provided with desktop, it is characterized in that: be provided with lowering or hoisting gear between support portion and the lifting column.
As a kind of improvement: the support portion lowering or hoisting gear comprises stepper motor, and stepper motor is connected with ultrasonic sensor with the picture altitude identification sensor.
As further improvement: the stepper motor gear matches with the lifting column of band gear.
The utility model makes the height of lectern can regulate the people of each speech voluntarily through adopting technique scheme; Lectern can be according to the needs of its height; Automatically regulate the height of lectern,, improve the speech effect so that reduce the fatigue strength of speaker when speech.
Below in conjunction with accompanying drawing the utility model is further described.
The technical problem that solves
1. the problem that lectern can not automatic lifting;
Lectern when automatic lifting to the decision problem of speaker's height.
Beneficial effect
The present invention contrasts prior art and has following innovative point:
1. can automatic lifting lectern height;
2. can judge speaker's height automatically;
The present invention contrasts prior art and has following remarkable advantage:
1. generally adopt artificial mode in the prior art, perhaps electro-hydraulic mode is regulated the height of lectern, wastes time and energy, and is not easy to the speaker and uses, and the present invention does not need manually-operated fully, judges speaker's height automatically, regulates the height of lectern automatically;
2. image recognition sensor that uses among the present invention and ultrasonic ranging sensor be with after stepper motor cooperates, and simple installation uses reliably, has solved the traditional problem that conventional hydraulic plays the falling unit leakage of oil.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment.
Among the figure: 1 image recognition height sensor; 2 ultrasonic ranging sensors; 3 desktops; The lifting column of 4 band gears; 5 stepper motors; 6 bases; 7 support portions.
The specific embodiment
Embodiment: shown in Fig. 1, a kind of lectern comprises base, and base is provided with the support portion, cooperates between support portion and the lifting column, and the upper end of lifting column is provided with desktop, it is characterized in that: be provided with lowering or hoisting gear between support portion and the lifting column.
Stepper motor is installed in the middle of the said support portion (7), and stepper motor (5) gear cooperates with a side of band gear lifting column (4).
Image recognition sensor and ultrasonic ranging sensor cooperate with stepper motor, judge speaker's height automatically, regulate the height of lectern automatically, and be easy to use.
Claims (4)
1. lectern; Comprise base (6), base (6) is provided with support portion (7), and the upper end of support portion (7) is provided with lifting column (4); It is characterized in that: said support portion (3) cooperate with lifting column (6), are provided with according to speaker's height apparatus for automatically lifting between support portion (7) and the lifting column (6).
2. a kind of lectern as claimed in claim 1 is characterized in that: said apparatus for automatically lifting comprises image recognition height sensor (1) and the actual height of ultrasonic ranging sensor (2) acting in conjunction measuring and calculating speaker.
3. like the described a kind of lectern of claim 1, it is characterized in that: said apparatus for automatically lifting provides power by stepper motor.
4. like the described a kind of lectern of claim 1, it is characterized in that: said support portion (7) adopt gear to match with lifting column (4).
